RECESS The Brooklyn Center City Council recessed at 7:10 p.m. and reconvened at 7:17 p.m. PRESENTATION TO CONSTITUTION BICENTENNIAL COMMITTEE CHAIRPERSON Mayor Nyquist stated he believes Brooklyn Center is one of the finest cities because of the extraordinary amount of volunteer citizen participation. He noted Bill Lakotas was chairman of the Brooklyn Center Bicentennial Committee, and the Council felt it was proper to recognize Mr. Lakotas' fine work on this committee. He continued by reading Resolution No. 88 -12 titled Resolution Expressing Recognition of and Appreciation for the Dedicated Public Service of the Brooklyn Center U.S. Constitution Bicentennial Committee and its Chairman, Bill Lakotas. RECESS The Brooklyn Center City Council recessed at 7:24 p.m. and reconvened at 7:40 p.m. 2 -8 -88 -3- PLANNING COMMISSION ITEM PLANNING COMMISSION APPLICATION NO. 87027 SUBMITTED BY DR. JOHN LESCAULT REQUESTING A VARIANCE FROM THE SIGN ORDINANCE TO ALLOW A 32 SO FT FREESTANDING HOME OCCUPATION SIGN AT HIS RESIDENCE AT 6142 BROOKLYN BOULEVARD The City Manager stated the Planning Commission recommended denial of this application at its December 17, 1987, meeting. He noted the City Council considered this item at its January 11, 1988, meeting and tabled the item for further staff review and comment. The Director of Planning and Inspection stated Dr. Lescault has provided staff with a copy of Chapter 2500, State Board of Chiropractor Examiners Board Rules. He noted in section 2500.0200 it states "all advertisements, of any nature whatsoever, including office designation and business displays must bear the name of the licensee or licensees." He stated the rule does require the doctor's name on the sign, however, the rule does not specify the size of the sign or that the word chiropractor or chiropractic must appear. Councilmember Lhotka inquired if it would be better to change the sign ordinance or grant a variance. The Director of Planning and Inspection replied, if the Council feels the size limitation is a hardship for the applicant, a variance could be granted. Mayor Nyquist inquired if the state is trying to preempt the City's sign ordinance. The Director of Planning and Inspection stated he did not believe the state is trying to preempt the City sign ordinance because state law does not mandate the size of the sign only that the name of the licensee or licensees must appear on it. Councilmember Theis inquired what the size of the requested sign is in the variance. The Director of Planning and Inspection stated the applicant has requested a 32 sq. ft. or less size sign. He noted this was the size of a 4' by 8' sheet of plywood. Councilmember Theis stated he felt that was rather a large size to place in a residential area. Councilmember Lhotka stated he would be willing to increase the sign size to 3 1/2 sq. ft. to accommodate the state mandate. The Director of Planning and Inspection stated it appears the need to add another name to the sign is what is causing the problem at this point. Councilmember Lhotka stated he believes a 2.5 sq. ft. sign is appropriate for home occupation, however, if state law mandates the licensee's name on the sign he believes an additional one sq. ft. would be appropriate. The City Manager noted if the City Council is leaning towards an ordinance change staff could bring in examples of different size signs for the Council to review. Mayor Nyquist recognized Dr. John Lescault, the applicant, who stated the true name of his business is not on the current sign because of the lack of space. He stated he agrees with the Council that a 32 sq. ft. sign is much too large for a residential area, but that is the size recommended by a sign company. There was a motion by Councilmember Lhotka and seconded by Councilmember Theis to table Planning Commission Application No. 87027 submitted by Dr. John Lescault and directing staff to prepare a proposed ordinance amendment to allow for specific circumstances when a larger sign is necessary. The motion passed unanimously. 2 -8 -88 -4- i ORDINANCES The City Manager presented An Ordinance Amending Chapter 21 Regarding Public Transportation. He noted this ordinance is offered this evening for a first reading and would provide for the establishment of taxicab rates by City resolution. There was a motion by Councilmember Lhotka and seconded by Councilmember Scott to approve for first reading An Ordinance Amending Chapter 21 Regarding Public Transportation and setting a public hearing date for March 14, 1988, at 7:45 p.m. The motion passed unanimously. The City Manager presented An Ordinance Repealing Ordinance No. 87 -15 and then Vacating Part of a Drainage and Utility Easement along the Southerly Lot Line of Lot 3, Block 3, Donnays Brook Lyn Gardens 4th Addition. He noted this item is offered this evening for a first reading. There was a motion by Councilmember Scott and seconded by Councilmember Hawes to approve for first reading An Ordinance Repealing Ordinance No. 87 -15 and then Vacating Part of a Drainage and Utility Easement along the Southerly Lot Line of Lot 3, Block 3, Donnay's Brook Lyn Gardens 4th Addition and setting a public hearing date for March 14, 1988, at 7:45 p.m. The motion passed unanimously. DISCUSSION ITEMS CITY ENGINEER'S REPORT REGARDING PROPOSED STREET IMPROVEMENT ON LOGAN AVENUE NORTH AND NORTH LILAC DRIVE FROM 57TH AVENUE NORTH TO 59TH AVENUE NORTH: FRANCE AVENUE NORTH FROM SOUTH CITY LIMITS TO 50TH AVENUE NORTH: LAKEBREEZE AVENUE NORTH FROM FRANCE AVENUE NORTH TO AZELIA AVENUE NORTH: AND 50TH AVENUE NORTH FROM FRANCE AVENUE NORTH TO T H 100 The City Manager stated the Director of Public Works and the City Engineer have a presentation regarding these proposed street improvements and will be available to answer the Council's questions. The Director of Public Works proceeded to review slides of each proposed project location and briefly explained the necessary improvements at each location. The City Engineer then reviewed each project and noted some areas are in much worse condition than others. He pointed out there would be some revisions to the existing system on France Avenue North which would involve realigning the catch basins. He noted however, the drainage problems found along Logan Avenue are much more severe than the conditions found at the other project locations. The City Engineer then went on to review the methods of financing the projects which include special assessments, regular municipal state aid funds, local municipal state aid funds, and the public utilities fund. He went on to review the assessment rates for each project and explained the rationale behind these rates. Councilmember Hawes stated he had some concerns regarding the proposed bike trail which would run east from France Avenue and 50th Avenue, along 50th Avenue to Drew Avenue. He noted there is a large amount of bus traffic along Drew and inquired if it would not be better to have the bike path along Ewing Avenue. The City Engineer noted the traffic count did not indicate a large amount of traffic along Drew Avenue but it could be reviewed and Ewing would be a good alternative. Councilmember Scott stated there is a drainage problem along 57th Avenue eastward from Logan to Humboldt Avenues. She inquired if the City 2 -8 -88 -5- foresees installing storm drainage along this area. The Director of Public Works stated that project would have to be coordinated with the County because it is a County road. RESOLUTION NO. 88 -28 Member Gene Lhotka introduced the following resolution and moved its adoption: RESOLUTION ESTABLISHING ASSESSMENT RATES FOR STREET IMPROVEMENT PROJECTS IN RESIDENTIAL AREAS IN 1988 The motion for the adoption of the foregoing resolution was duly seconded by member Rich Theis, and the motion passed unanimously. RESOLUTION NO. 88 -29 Member Celia Scott introduced the following resolution and moved its adoption: RESOLUTION RECEIVING ENGINEER'S REPORT AND CALLING FOR A HEARING ON LOGAN AVENUE IMPROVEMENT PROJECT NO. 1988 -04, FRANCE AVENUE IMPROVEMENT PROJECT NO. 1988 -05, LAKEBREEZE AVENUE IMPROVEMENT PROJECT NO. 1988 -06, AND 50TH AVENUE IMPROVEMENT PROJECT NO. 1988 -07 The motion for the adoption of the foregoing resolution was duly seconded by member Bill Hawes, and the motion passed unanimously. RECOMMENDATION FROM PARK AND RECREATION COMMISSION REGARDING ADVISORY COMMISSION BYLAWS The City Manager briefly reviewed the past history with regard to this item and noted the City Council had rejected this resolution amendment in November 1987. The Mayor stated he attended the last Park and Recreation Commission meeting and noted the chairman wishes to be able to paraphrase the Commission's specific position on any item. Councilmember Theis noted any time a person reports on the happenings of a meeting things will be paraphrased. He added he would suggest approving the Commission's recommendation for the proposed amendment. Councilmember Hawes stated he believes the chairman fears he will not have the ability to answer any direct question regarding the Commission or its actions without approval of the Park and Recreation Commission. He added the chairman has stated he will go along with the Council's decision. There was a motion by Councilmember Hawes and seconded by Councilmember Scott to reject the amendment to Article VII of the Bylaws. Councilmember Theis stated he felt the Council should the hear the chairman's position regarding this issue in person. There was a motion by Councilmember Theis to table this item until the chairman of the Park and Recreation Commission can be present at a Council meeting. The motion died for lack of a second. Upon vote being taken on the foregoing resolution, the motion passed with Councilmember Theis opposed. 2 -8 -88 -6- MAYOR AND COUNCIL'S SALARIES The City Manager briefly reviewed the elected official's salary survey which was completed by the Association of Metropolitan Municipalities. He noted it has been eight years since the Brooklyn Center City Council had an increase in their salaries. Councilmember Scott stated she believes an increase should be considered. She pointed out the City is quite far behind at this point in Council salaries and the longer the Council waits the further behind the salaries get. Councilmember Theis stated he would like staff to figure the average salary range for a population range of 25,000 to 35,000. Councilmember Lhotka left the table at 9:08 p.m. Councilmember Scott stated she would like staff to investigate starting some type of system that would automatically evaluate and raise the salary ranges for elected officials every two to three years. There was a general consensus among Councilmembers that a salary adjustment should be made to the Mayor and Councilmembers' salaries. Councilmember Lhotka returned to the table 9:10 p.m. RFP FOR ANALYSIS OF ISSUES RELATING TO RESIDENTIAL TREATMENT FACILITY MORATORIUM The City Manager briefly reviewed a draft RFP which relates to the City's current ordinance and the standards contained therein regarding residential treatment facilities. He noted a separate study should also be considered to cover the area of property value impacts from these type of facilities. He noted at this time staff has not completed a detailed cost analysis of either of the studies, but preliminary estimates range in the area of $10,000 to $15,000 for the property value impact analysis and in the area of $20,000 to $25,000 for the zoning ordinance and land use standards analysis. Councilmember Theis stated he believes the property value issue is very important. Councilmember Lhotka noted even if the studies cost as much as the high estimates the two studies put together would be less than the past law suit. There was a general consensus among Councilmembers that staff should prepare RFP's for the zoning rdinance and land use standards analysis a nd also a g Y value impact property pact analysis. MINNESOTA TRANSPORTATION FINANCE STUDY COMMISSION REPORT The City Manager stated he had attended a meeting of the Transportation Finance Study Commission recently. He noted this Commission assesses future highway and transit needs in the State, examines alternate revenue sources, and reports findings and recommendations to the legislature. He noted their report would be given to the legislature by February 15, 1988. He stated they will be recommending 30% of the motor vehicle excise tax (MVET) be transferred from the State General Revenue Fund to Transportation Related Funding. He added they will also be recommending a three cents per gallon increase in the gasoline tax and this would also be slated for transportation improvement. Mayor Nyquist inquired why only 30% of the MVET would be transferred to Transportation Related Funding. The City Manager stated initially it was intended 100% would be transferred for Transportation Related Funding. However, with the State's financial problems in the past, 100% of this revenue had been going to the 2 -8 -88 -7- general fund to fund other programs. He stated the Commissioner's believe 100% should go to highways but they cannot make such a drastic change over night and they feel 30% is a good starting point. There was a motion by Councilmember Lhotka and seconded by Councilmember Theis directing the City Manager to write a letter of support for the transfer of 30% of the motor vehicle excise tax from the State General Revenue Fund to Transportation Related Funding and also a three cents per gallon increase in the gasoline tax as an interim solution. The motion passed unanimously. ADJOURNMENT There was a motion by Councilmember Hawes and seconded by Councilmember Lhotka to adjourn the meeting. The motion passed unanimously.

That study and report have now been completed and the report recommends replacement of the pump and motor at Well No 6, as well as other reconditioning work. In addition, the study discovered a serious problem with the condition of the pump at Well No 8 (located at 7230 Camden Avenue No) and recommends that the pump at this well also be replaced. A detailed report from the City Engineer is attached. City staff has requested and received proposals to provide the necessary equipment and do the necessary work at both of those wells. Council action required Two resolutions accepting proposals to make the needed improvements are submitted for consideration by the City Council: ` CITY 6301 SHINGLE CREEK PARKWAY OF B ROOKLYN BROOKLYN CENTER, MINNESOTA 55430 C ENTER TELEPHONE 561 -5440 EMERGENCY - POLICE - FIRE E 911 TO: Sy Knapp FROM: H.

We have investigated and resolved the questions we had related to the proposals. The questions and recommendations are detailed below. RECONDITIONING WELL NO. 6 WATER IMPROVEMENT PROJECT NO. 1987 -24 Electric Service Modifications - We had two very different bids and needed confirmation from the low bidder that all of the needed modifications had been included. The low proposal of Bacon's Electric Co. includes the needed modifications. The company is familiar with the well house because it has made repairs to the electric systems there. It is my recommendation to accept the proposal of Bacon's Electric Co. Electric Motor - The proposal of Keys Well Drilling Co. was for a motor that did not have the efficiency specified. Over time the specified motor will more than save the difference in the proposal amounts. It is my recommendation to reject the proposal of Keys Well Drilling Co. because it fails to meet the specified efficiency required. Further, it is my recommendation to accept the proposal of Layne Minnesota Company. RECONDITIONING WELL NO. 8 WATER IMPROVEMENT PROJECT NO. 1988 -09 Deep Well Pump - The deep well pump proposed by the low bidder, Keys Well Drilling Co. is generally used in irrigation applications. We reviewed material specifications, pump curves and other submittal documents and determined that the deep well pump proposed by Keys Well Drilling Co. was not responsive to the CP 4 Water System Improvements February 22, 1988 Page 2 specifications. It is my recommendation that the proposal of Keys Well Drilling Co. be rejected because it was not responsive to specification requirements. Further, it is my recommendation to accept the proposal of Layne Minnesota Company. Respe tf 1 bmitted Approved for submittal k H.R.

CITY 6301 SHINGLE CREEK PARKWAY OF B ROOKLYN BROOKLYN CENTER, MINNESOTA 55430 TELEPHONE 561 -5440 EMERGENCY - POLICE - FIRE 13 C ENTER 911 TO: Sy Knapp, Director of Public Works FROM: H. R. Spurrier, City Engineer DATE: February 17, 1988 RE: Water System Improvement Projects No 1987 -24 and 1988 -09 (Rehabilitation of Well No 6 and Well No 8) Introduction The established operation and maintenance program for the City's 8 water supply wells provides a procedure whereby each well pump is periodically removed from the well casing for inspection, evaluation, and repairs or rehabilitation if necessary. On each well this procedure is completed on a five to seven year cycle, depending on our experience with each particular well. During this inspection the deep well pump, the motor, the well column, and other mechanical elements of the well are dismantled and inspected for wear; preventive maintenance is accomplished; and worn out parts are repaired or replaced as necessary. During each inspection we also examine the well cavity to determine whether the well should be reconditioned by bailing out sand deposits which may have accumulated in the well's cavity. Well No 6 (Located at 1207- 69th Avenue North) In October 1987, we removed the deep well pump from Well No 6 for routine inspection in accordance with the above described procedure. That inspection revealed considerable damage to the pump, indicating the possible need for replacement of the pump. In addition, a review of operating system records (from our new SCADA which was installed and placed in operation during the summer of 1987) identified this well as one which was not producing its design capacity. Accordingly, we tentatively concluded that the pump should be replaced rather than repaired. �01�V ,n Mo I We then reviewed the May, 1984 report prepared by Black and Veatch, consulting engineers, in which that firm recommended: (1) that if and when it became necessary to replace the pump at any well, the City should review the size of the pump and increase or decrease it as indicated so as to assure that the use of each well is optimized; and (2) that when the pump for Well No 6 is removed for inspection, the "pump column" for this well should be extended - again to optimize the use of the capacity available from this well. On November 9, 1987, the City Council, at our request, approved a contract for a detailed study and evaluation of Black and Veatch's recommendations, with particular emphasis on Well No 6, using Short - Elliott- Hendrickson (SEH), as our consulting engineers for this study. Since that time, SEH and City staff have conducted detailed studies of Well No 6 and, at a meeting held on February 11, 1988 we concluded the following: 1. The um at this well is worn u laced. n o t and needs to be re P P p Note: This pump was replaced in 1982, but has worn out in less than 6 years because (1) the water from this well is fairly aggressive; i.e., it has a low pH; and (2) until the SCADA system was installed, this was the only well equipped with automated controls. Accordingly, it was used as the "work horse" of our well system. The new um which Y pump we propose to purchase will have a protective coating on those surfaces which are most vulnerable to corrosion and wear. 2. The motor at this well is also extensively worn. Note: This is the original motor which was istalled when the well was developed in 1965. 3. The most cost effective rehabilitation of this well is to replace both the um and th p p e motor with a larger pump and a larger motor (i.e., a new 150 hp motor in lieu of the old 125 hp motor). This also necessitates increasing the capacity of the electrical service and changing the g g electrical service from 240 volts to 480 volts. By replacing the motor with a.150 H.P. motor, the "normal" production capacity of the well is increased by 10 %, while its capacity during peak demand periods (i.e., all wells operating) is increased by 17 %. If considered on a "cost- per - gallon -per- minute" basis, the cost effectiveness of this expenditure is much greater than the cost effectiveness of developing a new well. 4. The pump column at Well No 6 should be extended 30 feet deeper. By extending the pump column, the ability of the well to continue to deliver water during maximum drawdown (i.e., peak demand) periods is considerably improved. 5. Other mechanical elements of this well need to be repaired or replaced. This includes replacing portions of the drive shaft and segments of the old pump column along with other appurtenances. 6. There is no need to bail out any sand deposits at Well No. 6 at this time. Accordingly, we have prepared technical specifications for the furnishing, delivery, and installation of all required work and equipment, and we have requested proposals for these improvements. For the purpose of getting the best prices and expediting work on this project, separate proposals were requested for the following work items: 1. Furnishing and installation of the deep well turbine pump, extension of the pump column, replacement of defective sections of pump column and of the drive shaft, and other appurtenant mechanical repairs and replacements; 2. Increasing the capacity of the electrical service to the well; 3. Furnishing and delivery of the new electric motor (which will be installed by the well contractor). A summary of the proposals received for each of these work items is shown on the attached resolution. We recommend that contracts for this work be awarded to the low bidder for each item. Well No 8 (located at 7230 Camden Avenue North) During SEH's study, testing and evaluation of the City's well system it became apparent that an additional problem had developed at Well No 8. Well No 8 was fully reconditioned in 1985 in accordance with the City's established operation and maintenance program. However, that same well experienced a collapse of a portion of the well cavity in Spring of 1987. You will recall that we proceeded on an emergency repair basis during late spring and early summer of 1987. Because the contractor on that project experienced severe problems (continuing collapse the cavity and loss of equipment) this project took longer than originally expected. During that time the City experienced the highest water demand.in the City's history. Accordingly, we placed top priority on getting Well No 8 back in service as soon as possible. Because the pump had been fully inspected in 1985, because we had had no operational problems with the pump in this well, because we didn't expect the well to be non - operational for an extended period and because we wanted to get this well back in service as soon as possible, we did not dismantle and inspect the pump in 1987. Now, however, SEH'S testing and evaluations have shown that the pump at Well No. 8 apparently is severely worn - most probably as a result of pumping a large amount of sand at the time when the well cavity collapsed last year. Testing has shown that, while the pump can produce approximately 95% of its "design capacity" when it is operating alone it will actually fail to pump any water when all other wells are operating (i.e., during our peak demand periods). Accordingly, since it is our opinion that the pump at Well No 8 must be replaced we have obtained proposals for this work (see resolution), and recommend award of a contract to the low bidder. It is noted that the majority of the costs for work on Well No. 8 are for the furnishing and installation of the pump. The cost of removing and installing the pump (i.e., the cost which might have been saved had we replaced it while the other work was being done last summer) is approximately $1,000. Summary and Recommendations The work outlined above is a necessary part of the City's established operation and maintenance program for the purpose of maintaining the City's water supply. It is our belief that the additional studies conducted during the past three months have identified the most cost effective program for improvement of Well No 6 and have (unexpectedly) called our attention to the existence of a serious problem at Well No 8. It is also noted that the existence of the City's new SCADA system made it much easier to detect and analyze the problem which was occurring at Well No 8. The bidders who submitted proposals for furnishing the specified equipment have stated that the delivery time for this equipment will be approximately 4 to 6 weeks. Accordingly, it is requested that the City Council award the contracts for this work immediately so that the equipment can be ordered, delivered, and installed and so that both wells can be- placed back into operation before the start of the heavy water use period this summer.

As noted in the attached article from the State Shade Tree Advisory Committee Report several other infectious diseases, including "Oak Wilt ", the "Gypsy Moth ", and "Ash Yellows" are beginning to attack the "Urban Forest ". Accordingly, it is recommended that the ordinance be amended to cover all infectious tree diseases. Based on our knowledge of these diseases we would expect that the amount of enforcement required, and the number of additional trees affected by those diseases will be quite limited during the next several years. However, by amending the ordinance to generically cover all infectious diseases, the City can place itself into position to prevent problems, rather than reacting to them after they become severe.

Trees? Yes. Like the other elements of the urban infrastructure, the forest of trees - -the urban forest - -that literally covers our towns and cities is deemed to be an essential part of that collection of elements which Minnesotans require to create liveable communities. Our urban trees, like the rest of our urban infrastructure components, have some serious problems these days, and they require our attention. More precisely, all these elements of our community infrastructures require the attention of our State leaders, because our State is nothing more and nothing less than the sum of its urban and rural areas. If one element is allowed to decay, our entire State will be hurt. These days primary attention is properly focused on our present great rural crisis. But ether future crises can and should be prevented by timely action now! Because our state is relatively young, we have only recently had to face the fact that elements of our cities and towns grow old, deteriorate, and must be preserved, renewed and extended. Heretofore, other areas of the country have had to deal with declining and aging built -up areas and urban infrastructure components to a much greater extent than "young Minnesota." But now we have to think not only of renewal and planning for the downtown areas of a few major cities. We must face the fact that almost all the areas of Minnesota have to think of maintaining or otherwise renewing and updating their community infrastructures in the same way that the owner of an older house must focus on updating or replacing not only his or her roof, but also the electrical system, plumbing, siding, heating system and landscape of the house. The owner neglects such work at considerable peril. Our urban forests are no exception to this need for urban maintenance, renewal and updating. If we neglect them, the cost will only rise later. Winston S. Churchill once commented that the English speaking peoples are much better at dealing with crises than at preventing them. Sadly, Minnesotans appear to fall squarely within the scope of Churchill's indictment. In the mid 1970s the Legislature, the Governors, the State Agencies and the University responded with great vigor to help cities and towns deal with the great loss of American elms due to Dutch elm disease. Large sums of state money, technical assistance and public information were provided to help communities slow the losses and plant over 750,000 new shade trees. As a result of that action, many urban areas have preserved many thousands of healthy mature elms and now are maintaining even more healthy young trees of other species. The northern and northwestern parts of the State were sadly shortchanged when the State program was halted during the budget crisis of the early 1980s, but in the rest of the State the communities had been helped to overcome the crisis. Those communities got the situation under control, and started to repair much of the damage to the urban forest component of their infrastructure. In short, Minnesotans, true to Churchill's prediction, did a rather good job dealing with a crisis. But other crises loom in our urban infrastructure. If not effectively dealt with and prevented now, they will become huge and expensive problems later. A relatively small sum spent now can solve many problems that later will require much more costly solutions. We can provide the proverbial single stitch now in the fabric of the urban forest component of our urban infrastructure which will prevent the requirement for ten costly stitches later: "A stitch made in time saves nine." The State Shade Tree Advisor Committee, in its Seventh Biennial Report to Y p the Governor, the Legislature, the State Departments and the University of Minnesota, is here proposing an integrated multi- agency but very modest effort at stitching up the present rips before they become the huge gashes we know are coming. What we propose may not be as exciting to read about as some of the other "hot issues" of our day, but if you ignore it - - the Legislators and other government officials totally ignored Dutch elm disease when they could have stopped it with a single stitch in the early 1960s before it got out of control - -the costly mending process required later will be your unwelcome legacy to our State and its citizens. To you, our leaders, who will make the choice to act now or to let things deteriorate into major and very expensive problems in a few years, we dedicate this Report, and it is to you that this Report is ...

EXECUTIVE SUMMARY The urban forests covering every city and town in Minnesota did not just happen. They are as much a part of our community infrastructures as are roads, libraries and bridges. And, like those other elements, our community trees require careful planning, tending and renewal if they are to provide continuing benefits. The State Shade Tree Advisory Committee has been reviewing the status of and advising our State on our urban forests for 12 years. We here present a low- budget (under $1,000,000 per year) integrated multi - agency program to cope with present problems and prevent expensive future disasters. It will save far more than it costs. We recommend that the Department of Agriculture's Shade Tree Program (presently costing $225,000 per year) be expanded to cover more than just Gypsy moth (dangerous though that plague is to our rural and urban forests) by adding $58,000 per year to provided for badly needed public information efforts. The Department of Natural Resources has utilized its District Foresters extensively to provide urban forestry assistance in those parts of the state where it has a major presence. We recommend that the DNR Forestry Division's budget be increased by $190,000 per year to fund four positions (to be located in the DNR's four out -state regional offices) to work with the MDA Shade Tree Program in assisting communities and individuals in those areas. Oak wilt is the most dangerous tree disease threatening our suburban trees and forests and one of the greatest threats to our valuable rural forests. Minnesota's oaks are under substantial risk, but unlike Dutch elm disease (which can only be slowed, albeit profitably so), oak wilt can be stopped. We recommend establishment of a joint MDA -DNR program to manage oak wilt in suburban and rural Minnesota at a cost of $250,450 per year ($159,150 to MDA and $91,300 to DNR). The economic threat of oak wilt justifies this expenditure many times over. University of Minnesota resources can provide much needed research and extension. Because of U of M budgeting processes, the only practical way to get this research in 1988 -1989 is to appropriate $195,000 per year to MDA to contract with the U of M for necessary shade tree (including oak wilt) research and extension. The Minnesota Department of Education helps solve our environmental programs by observing the ancient maxim that "As the twig is bent, so grows the tree." We recommend that our State benefit by the vast leverage it can obtain through educating its young people on the value and the needs of our urban forests. Thus we recommend that $48,000 be added annually to the MDE budget for preparing and disseminating necessary curriculum materials to Minnesota schools. In addition to the above program, we recommend separately that the presently unfunded community grants program existing in the statutes be renewed and funded at $2,500,000 per year to assist communities (especially those in the northern and western parts of the State) to deal with problems of their urban forests. 4 State Shade Tree Advisory Committee Report, September 1986. . I. A VERY SHORT HISTORY OF THE URBAN FOREST AS A PART OF MINNESOTA'S URBAN INFRASTRUCTURE: ITS PAST, ITS PRESENT, AND ITS PROBLEMS In the beginning in Minnesota there were no urban forestry problems because there were no urban forests. Part of the state was virgin forest, the rest was virgin prairie. In one part the problem was to cut down the huge old trees and market the lumber. In the other part the problem was to break the prairie and begin the farming operations that have produced the great harvests which are part of our very large rural crisis today. But as citizens began to build our communities, they began to plant trees. Almost all of the large old elms, oaks, ash, lindens, pines and spruces we see in Minnesota were planted by energetic pioneers in the towns they were building. They had the advantages of rich, non - compacted soil, few or no cars, little paving, a civic attitude that promoted individuals to care for the trees around their homes, and, perhaps most important, a widespread distribution of the knowledge of how to care for plants and trees that is inherent in those who work with the land in an essentially rural setting. The work of the pioneers and of the builders of the earlier part of this century served us well. Our cities and towns grew beautiful and became pleasant places as their large scale tree plantings matured into the grand old specimens we now revere. But nothin` lasts forever without care and renewal, and the urban forests are no more an exception to that rule than are the houses, barns, firehouses, water and sewer lines, brick roads, libraries, and schools which our forebearers built. Furthermore, just as many of our urban forests matured, they were set upon by two huge disasters, with other disasters lurking in the wings, waiting for an opportunity to explode upon us. Dutch elm disease and oak wilt are well -known problems, and we will present just a summary of those twin plagues here. Readers are referred to Appendix A to this Report which contains a more detailed history of the progress of these diseases and what the State did (and did not) do about them. Another part of the history of the problems of our urban forests is less well known. That part concerns the other problems which form the new threats to our urban forests. A few of the major ones are also described below: A. Oak Wilt 1. Importance of Oak Wilt Oak wilt is the most serious disease of shade trees in Minnesota. It is true that the American elm was a dominant tree species along boulevards (and still is in many older cities such as St. Louis Park, Robbinsdale, Duluth, and others), in parks and in many yards. But oaks outnumber elms in metropolitan areas almost two -to -one and will increasingly be the dominant tree species as communities grow into the surrounding countryside. 5 State Shade Tree Advisory committee Report, September 1986. Each year more oaks are killed by oak wilt than elms are killed by Dutch elm disease, including such years as 1977 when St. Paul alone lost over 50,000 elms. The disease has spread very slowly northward in Minnesota to a line from St. Cloud to Taylors Falls, and west to a line from St. Cloud to Mankato, and south to Iowa. Because this disease can be spread long distances by human activity, it is an imminent threat to all our vast northern and western forests, in all of which oak is a significant component. In a survey conducted statewide last year, 241 communities in 49 counties reported losses to oak wilt. The toll in our hardwood forests is yet to be determined. There are approximately 234,000,000 oaks in Minnesota, based upon the DNR /U.S. Forest Service Phase I Inventory conducted in 1978. Oaks grow in a wide variety of sites. They can tolerate very poor soils where few other tree species survive; they last far longer than elms (often surviving for upwards of 200 years); and they have few problems other than oak wilt and construction damage. They are attractive, sturdy and highly valued both as a shade tree and as a timber species. The officials of our State must consider these facts: • A single large red oak can add $10,000 to the property value of a residential lot! • Oak is currently the primary wood used in the manufacture of furniture, cabinets, millwork and flooring! • 45,000,000 board feet (approximately) of red oak is sawn annually to supply our secondary wood industry, which employs 16,000 Minnesotans! • Cabinet manufacturing is a $160,000,000 per year industry in Minnesota, and Minnesota has the largest cabinet producing industry in the Midwest. Red oak accounts for 90% of the lumber used by Minnesota's cabinet manufacturers! • There is a substantial foreign demand for Minnesota's oak lumber, logs and products. However, many foreign countries have placed severe restrictions on the importing of oak from Minnesota due to the presence of oak wilt in our State! Clearly, the oaks are a resource which deserve our concern. The good news, discussed in detail below, is that oak wilt can be stopped and even eliminated. 2. Cause of Oak Wilt that induces us plugging Like Dutch elm disease, oak wilt is caused by a fungus p gg g of the water - conducting system of the tree. It affects red oaks most readily but is a menace to all types of oaks. After an infected red oak dies the fungus colonizes the wood under the bark and produces a "mat" of spores. (Surprisingly, other types of 6 State Shade Tree Advisory Committee Report, September 1986. oaks do not produce this mat, even though they can be infected with oak wilt.) As this mat on an infected red oak thickens, it exerts sufficient pressure to split open the bark, releasing a fermenting odor. The common picnic beetles (known to scientists as the sap- feeding Nitidulid beetles) are attracted to this odor. They feed on these mats in great numbers and then carry spores to existing fresh wounds on healthy oaks, where infection results. Herein lies the important difference between oak wilt and Dutch elm disease. Elm bark beetles create wounds by feeding in elm twig crotches to introduce spores. In contrast, a fresh wound must already exist in an oak in order for the picnic beetle to deposit oak wilt spores. For this reason Dutch elm disease spreads overland much faster than oak wilt. Also for this reason oak wilt is controllable and may even be eliminated. Almost all oak wounds, into which oak wilt can be spread, are due to human activity, especially new home construction. By mid -May, the ground has thawed enough to allow bulldozers to clear brush and stumps and to grade new home sites. Bulldozers take to the woods in large numbers, gashing trunks and breaking limbs off trees that builders often have promised to save. If oak wilt is present anywhere nearby (up to a few miles away), the stage is set for rapid spread into the wounded trees. Picnic beetle activity and oak wilt mat production are greatest in May and June, when otherwise healthy oaks are highly susceptible to infection. The growth of our communities into the wooded countrysides has resulted in a dramatic increase in this artificial spread of oak wilt. The situation is further aggravated when the uninformed homeowner prunes his or her oaks in the spring. After one oak is infected in a grove of oaks, another means of spread of the disease sets in. As an infected oak wilts and dies, the fungus is drawn into adjacent healthy oaks through their interconnecting root systems (root grafts). Since oaks (more so than elms) tend to grow in pure or nearly pure stands, especially on poor sandy soils, they are quite susceptible to progressive destruction if one member of a stand is infected. More than 95% of all new oak wilt infections result from root graft transmission. But this transmission is relatively slow. Scientists estimate that oak wilt moves through grafted root systems at the rate of 15 -20 feet per year. 3. Management of Oak Wilt There is no "cure" for oak wilt in the sense of a cure for human diseases, such as vaccines for chicken pox or antibiotics for bacterial infections. Therefore, management of oak wilt consists of preventing the disease from spreading to healthy trees. The chief component of a management program is education, to teach people not to prune or otherwise wound healthy oak trees during May and June. The second component is to cut the interconnected root systems so the spread of the disease in an infected area is halted. A modified vibratory plow, of the type normally used to bury telephone or power cables, has proven most effective in stopping root graft spread of oak wilt. The third part of a management program 7 State Shade Tree Advisory Committee Report, September 1986. consists of preventing sporulation of the fungus by treating those few trees on which spores will form in May and June. Because oak wilt is slower moving than Dutch elm disease, a modest program in each community with sizeable oak populations, combined with a similarly modest but widespread spotting and information disseminating program in rural areas, can reduce the disease to a minor problem. If left unchecked, and if aided by ignorant construction and pruning activities, oak wilt will destroy large portions of our exceedingly valuable oak forests - -both urban and rural. B. Dutch Elm Disease Dutch elm disease has been talked about so much that it has become a bore to some people. But as long as there are American elms (there are no "Dutch" elms in Minnesota- -Ulmus hollandica cannot survive our cold, dry winters) there will be Dutch elm disease. The disease is named for the nationality of the scientists from The Netherlands who identified it, even though its origin is probably somewhere in China or western Asia. It is caused by a fungus infection which results in a clogging of an infected tree's vascular system. The tree dies because water cannot travel up the trunk through the branches to the leaves. The agent for the spread of the disease (the "vector" in scientific terms) is a tiny beetle, a little larger than a pin head. There are two types of beetles: native elm bark beetles and European bark beetles. The beetles only lay their eggs under the bark of dead or dying elms. In their nests, the Dutch elm disease fungus "blooms" or, as scientists say, it sporulates. The young beetles carry the spores of the fungus on their bodies. The only place that the European beetles feed is in the crotches of the tiny branches high in elm trees. During feeding, the spores drop from their bodies into the small wounds in the trees caused when the beetles eat the tender cambium cells in the twigs of the elm trees, and infection results. The cycle (or, more properly, the "spiral ") is a vicious one. The more infected, dying or dead trees there are, the more beetles there are. The more beetles there are, the more dead or dying trees there are. Left unchecked, this spiral results in the virtual elimination of all American elms. This is especially sad since American elms are perhaps the best possible urban shade tree from the standpoint of their beauty, size, ease of transplanting, rapidity of growth and adaptability to hostile urban soil, water and air conditions. The key thing to understand about Dutch elm disease is that controlling it (and thus limiting losses and attendant costs) consists in doing just what will have to be done in any case, namely removing diseased trees and disposing of them properly. Through local control programs (aided mightily by the large State aid program which was killed in 1981 -1982 during the State's budget crisis), many communities in Minnesota have controlled the spread of Dutch elm disease and are limiting annual losses to a small percentage of their elm populations, thereby cutting annual costs for removal to a tolerable level. These same communities are using the time they buy with their control programs to plant new shade trees of other species so that their streets and parks are never going to have to go through a treeless, "start-over phase." 8 State Shade Tree Advisory Committee Report, September 1986. r f C. Gypsy Moth Someone once said "If you like Dutch elm disease, you'll love the Gypsy moth." If there is a "take -all" plague threatening our urban forests, it is the Gypsy moth. Gypsy moths have invaded most states of the eastern U.S. after escaping from a person who had imported them in an effort to make silk. Gypsy moth caterpillars are the omnivores of the urban forest. They will eat just about anything that is green, but their preference is for shade trees, especially oaks, aspen and birch. When they have stripped those trees of their leaves, they will eat other trees including evergreens, bushes, and even sometimes the plastic of the traps set to catch them. The G YPY YPY Gypsy moth is called "Gypsy" " because of its habit of catching a ride on anything that moves. A prime method of transmission is the household goods moving industry. A prime offending class of movers is, unfortunately, that of the corporate executive, whose moves are frequent and are paid for by the company for whom he or she works. Thus, the moving executive often has everything moved, including picnic tables, firewood, and other items which less favored individuals would leave behind when they move. Gypsy moth egg cases laid under picnic table tops and on other yard items often are imported into Minnesota that way. Given favorable conditions, the Gypsy moth population can explode and start to strip whole areas of their green vegetation. Trees without leaves cannot produce sugars tl:ev need to survive. If a tree is stripped once, it usually has enough stored energy to put out new leaves. But if it is stripped in successive seasons, death often results. Once the Gypsy moth population has exploded, there is no chance to eliminate it, even with powerful and often dangerous insecticides. It can only be managed at very considerable cost. Up to the present time, Gypsy moth colonies in Minnesota have been detected and infestations have been eliminated using biological controls and limited insecticide spraying. This program is being carried out by the Minnesota Department of Agriculture with very limited funds provided from the present Shade Tree Program appropriation made by the 1985 Legislature, in cooperation with the Department of Natural Resources and the U.S. Department of Agriculture. Traps have been set out in many areas in Minnesota by the Minnesota Departments of Natural Resources and Agriculture to monitor the presence of Gypsy moths. When they are detected, the joint program conducts a more intensive search effort and, if necessary, implements an eradication plan in a limited area. This program must be continued if Minnesota is to avoid a disaster. D. Ash Yellows After the loss of the American elms due to Dutch elm disease, green ash were planted in great numbers in many communities (especially in newly developed areas), in spite of public warnings from The State Shade Tree Advisory Committee and by many experts that Minnesotans should not be so unwise as to dash from the 9 State Shade Tree Advisory committee Report, September 1986. disaster of Dutch elm disease into the danger which could result from unplanned planting of too many trees of another single species. We strongly advised that communities draw up careful plans for replanting after the loss of elms and for planting new subdivisions. We advised against reliance on any one species. Anyone who tours the average new suburban development can see that this advice was totally disregarded. We also advocated that several million dollars be spent on researching and developing new shade tree species, so that we would not be so dependent on a few species. That advice, too, was disregarded. We predicted disaster if our advice was not heeded. Now, in 1986, it appears that our prediction may be coming true. A disease called "ash yellows" is killing large numbers of rural and urban green ash trees and is causing significant problems for nurseries growing shade trees for sale. Based upon work done by Dr. David French and others at the Department of Plant Pathology at the University of Minnesota in cooperation with scientists from across the country, it now appears that ash yellows is caused by what is called a "mycoplasma -like organism " - -an organism smaller than most bacteria, but larger than viruses. Many scientists believe that ash yellows is spread by the ubiquitous "leaf hopper" a small insect that leaps from one plant to another, sucking the juices and spreading the disease. Leaf hoppers are well known to gardeners as the agent for the spread of "aster yellows," a disease that kills asters and marigolds. The insects can be carried long distances on wind currents when temperature and humidity conditions are right. At ffie present time nothing is known about any cure for ash yellows disease. Most plant diseases are not "cured" anyway. What is done is that resistant strains of the plants are discovered or created by breeders. Nothing is known about resistant strains of ash, either. The ash is an important hardwood forest species and is being severely wi threatened in eastern Iowa and other laces b ash s e yellows. ash s very P Y Y Y important to the wholesale and retail nurser trade with sales f amounting to P Y � g g many millions of dollars annually. E. Other Tree Diseases There are a number of other tree diseases of varying seriousness. The widely planted honey locusts are often killed or badly disfigured by Necrria cankers - -large wounded and dying areas on the trunks and limbs which cause the portion of the tree above the cankers to die. Sugar maples, in addition to suffering when they are planted in poor, sandy, dry soils or in hot locations, suffer from a number of other diseases. The list could go on and on, because most currently available trees are not as hardy and as trouble free as the widely planted American elm (with, of course, the one large exception of Dutch elm disease). We should note that this is cause for concern and cause for action, but not for despair, since shade trees are no different than human beings, farm animals, or common agricultural crops. They are subject 10 State Shade Tree Advisory Committee Report, September 1986. to a host of problems. These problems are not overly difficult to solve or to circumvent. But they will require some effort. Unfortunately, for too long Minnesotans have taken their trees and the health of their urban forest for granted in a way which they have not done with their own health, or with the health of their agricultural animals and crops. Almost no money has been put into shade tree research and even less money has been put into planning. Such penny pinching is simply foolish, and is proving to be very, very costly to our State. F. The Human Problems of Shade Trees The diseases described above are certainly bad. But far worse in total is what human beings -- Minnesota citizens - -are doing to their shade trees through ignorance or design. These problems result in much loss and great expense, and most of them could be minimized or avoided. Among them are the following: 1. Construction Damage A great deal of building is going on in the hardwood forests which surround many of our urban areas. Many commercial home builders seem almost willfully stubborn in refusing to acknowledge what most other people know: a tree's roots are as important to its health as are its branches and leaves. By smothering a tree's roots with fill, the tree is almost certain to die within one to three years. Scientists have long known that the average tree's roots are very sensitive and extend far beyond the range of its branches. Roots absolutely must have oxygen in order for the tree to be healthy. It is not enough to protect a tree's trunk from damage during construction operations. Its entire root system must be kept from being smothered, cut, or compacted. Builders are almost certainly committing fraud or are guilty of gross negligence if they sell new homes on wooded lots at a premium when many of the trees on those wooded lots are almost certain to die soon because of the builders' actions. As noted above in the section on oak wilt, construction damage is the principal cause of the overland spread of oak wilt. 'Such construction damage is resulting in the needless death of many millions of dollars worth of shade trees every year in areas where new construction is taking place. 2. City Conditions Trees to be planted in 1987 in cities and towns will face far greater problems than the trees planted by our great, great grandparents in 1887. Soils have been compacted for a century or more; they have been leached of nutrients; cities and towns have large expanses of paving that often becomes hot enough to fry eggs in summer, and then provide large open sweeps for bitterly cold winter winds. Broad -leaf weed killers are applied to lawns with almost reckless abandon and certainly without notice that the maples and birches growing in the lawns also have broad leaves. Lawn mower casings are smashed into the tender bark of young trees in an effort to get close to the trees, and if that fails to eliminate all the grass then 11 State Shade Tree Advisory Committee Report, September 1986. weed whips are held up against the tree, eating away not only grass but also sensitive cambium layers of the trees. The trees soon die as a result. Young hoodlums tear down trees in acts of stunning bravado and cunning skill and, surprisingly, very few young trees are able to run away from these conquering heroes! Engineers decree that sidewalks and streets must run in exactly straight lines, and like the mythical Greek giant Procrustes himself, they cut off the offending members of trees which do not fit into the Procrustean beds of their engineering designs. Compaction of the soil around trees due to construction activities or just from repeated use by people severely inhibits the ability of trees to grow and often kills them. The list of sins against the trees of our urban forests is as long as it is sad. It is a tribute to the strength and adaptability of urban trees that there is any green at all in many parts of our cities and towns. Against the twin tree diseases of human greed and human ignorance, only public education serves as a vaccine. 3. Poor Planning If our urban roads and sewer systems were as poorly planned as are many portions of our urban forests in Minnesota, the engineers who had committed such atrocities would certainly be asked to seek other employment. Much of the costs that Minnesotans will be incurring in replacing and modifying their urban forests in the future could have been greatly limited by better planning. Even though trees are the most visible element of the urban infrastructure, and one of the most valuable parts thereof, there seems to be a widely held view that planning for urban trees is a frill and is not necessary in days of tight budgets. If a legislator or a city council member insisted that no plans were needed for a new sewer system, or that the location and design of a new fire station did not deserve careful engineering and study and the expenditure of at least a modest amount of funds on planning, that public official would probably be laughed out of office. But all too often our leaders seem to be totally unwilling to spend any money planning the urban forest, which may be expected to last far longer than most other public utilities (and the urban forest is a public utility, make no mistake about it). A modest sum spent on studying soil conditions, building locations and heights, street and other utility locations, and on carefully selecting appropriate species for different locations would save a community much money over the decades in which the trees being planted may reasonably be expected to live. 4. Poor Maintenance Most people would never assume a lawn in front of their house or civic building needed no water or mowing, and would never assume that a roof on their home or school never needed repair, and would never think that a street did not need to be patched and seal- coated at regular intervals. But many of these people, all of them good Minnesota citizens, seem to have the idea that since only God can make a tree, He will take care of it once it is planted. Apparently this is asking too much of the Almighty in light of the many other concerns which demand His attention in the 1980s, because poor maintenance seems to be one of the mayor 12 State Shade Tree Advisory Committee Report, September 1986. 5 causes of the failure of many of the new trees planted in our urban forests as communities seek to rebuild that element of their urban infrastructure. Our big elms did not rise so majestically into the air around our homes because their trunks lengthened! Their lower limbs were pruned off and the trees were watered, fertilized and protected by our forebearers. If Minnesotans expect to have urban forests in the future which are a source of pride and enjoyment to their State, they must be prepared to pay a little attention and devote a little skill to the maintenance of the trees they plant. Frankly speaking, maintenance is an especially large problem in small communities, which often do not have the resources (or refuse to levy taxes) sufficient to pay for pruning work on street and park trees. With liability considerations becoming increasingly important to city budgets, proper maintenance and pruning of street trees is not only necessary for the creation and maintenance of an attractive community; it is necessary as well to avoid losses. II. PLANNING FOR THE FUTURE: PREVENTING PROBLEMS, NOT JUST DEALING WITH THEM The Minnesota State Shade Tree Advisory Committee requests that the leaders of our State acknowledge that our urban forests are here to stay and that the urban forest part of our urban infrastructure is not going to go away any more than are our paved roads and other civic amenities, because Minnesotans want cities and towns with handsome shade trees. If that request is granted, then we advise and recommend that the State adopt a modest, sensible and effective program for assisting communities in preserving, planning, renewing and protecting our urban forests. The first responsibility in this area obviously lies with communities. They are the ones who must decide to devote some small portion of their public revenues to trees as well as to sewers and libraries and other urban elements. But the State of Minnesota has a very important role to play. In our view, the State must do what the individual communities cannot do at all, or cannot do nearly so well, for themselves. The remainder of this 1986 Report is directed to our recommendations on what the State can and, in our view, should do. Central to our recommendations is that the State must take the long view and recognize that the problems of our urban forests are not ones which can be focused on for a few years and then dropped entirely when budgets get tight, as they do periodically. The actual expenditures recommended by us are small- -even tiny. And they are made with a clear understanding that our rural and urban areas face many great problems calling for vast expenditures of State and local revenues. 13 State Shade Tree Advisory committee Report, September 1986. But our recommendations are made on the assumption that the State and its leaders recognize that we must think and plan and work on the problems of our urban forests now and for many years to come if we hope to avoid costly ecological disasters like Dutch elm disease and if we hope to solve pressing and expensive threats like oak wilt, ash yellows, poor planning, limited tree species availability, frauds against buyers of new homes on wooded sites, and the like. III. THE PROPOSED PROGRAM FOR THE 1988 -1989 FISCAL YEARS The Minnesota State Shade Tree Advisory Committee is here proposing a lean, integrated, multi - agency cooperative program for the State's effort in managing the multi- billion dollar element of our urban infrastructure which we call "the urban forest." There are four State agencies involved in the proposed cooperative urban forestry program. Each of these agencies has a unique and mutually supportive role. The Minnesota Department of Agriculture and the Department of Natural Resources function to provide survey, disease management (and, in some cases, eradication) efforts, and informational and market services. The Colleges of Agriculture and Forestry of the University of Minnesota have specialists on their staffs capable of providing the research which is badly needed, and capable of developing information and publications required if that research is to be properly utilized. The Department of Education performs the vital role of educating our young people on the value of our urban environments and the all- important role which knowledgeable citizens must play in preserving and improving that environment, of which our urban forests are the largest and most visible part. We have studied each of these elements for a long time, and have thought and debated a great deal about how they all fit together. We strongly recommend that you do not implement the program piecemeal, because we have purposefully designed a program that builds upon the strengths of various elements of our State government, and which requires all of these elements to work together and to contribute achieve t benefits we know are attainable. To understand i we hope to ach a he be f P f n co nsider the elements in a somewhat w in it will be necessary s what a are proposing P P g �7' to co separate fashion and then to view them as part of an integrated, teamwork effort. In summary, we propose a State government interdepartmental program with four major components: (1) The Minnesota Department of Agriculture ( "MDA ") would continue to conduct the programs presently being conducted in the Shade Tree Program authorized by the 1985 Legislature and which would be expanded on a modest basis to allow it to participate in the interdepartmental oak wilt control program discussed below. In addition, the MDA would receive a limited amount of funds to allow it to carry out a small but effective public relations program, since so much of 14 State Shade Tree Advisory Committee Report, September 1986. MINUTES OF THE PROCEEDINGS OF THE PLANNING COMMISSION OF THE CITY OF BROOKLYN CENTER IN THE COUNTY OF HENNEPIN AND THE STATE OF MINNESOTA REGULAR SESSION FEBRUARY 11, 1988 CITY HALL CALL TO ORDER The Planning Commission met in regular session and was called to order by Chairman George Lucht at 7:35 p.m. ROLL CALL Chairman George Lucht, Commisssioners Molly Nalecki, Mike Nelson, Bertil Johnson, and Wallace Bernards. Also present were Director of Planning and Inspection Ronald Warren, City Engineer Bo Spurrier and Recording Secretary Nary Lou Larsen. Chairman Lucht stated that Commissioners Lowell Ainas and Ann Wallerstedt were unable to attend this evening's meeting and were excused. ADMINISTER OATH OF OFFICE The Secretary administered the oath of office of Planning Commissioner to new Commission member Bertil Johnson. APPROVAL OF MINUTES - JANUARY 14, 1987 Motion by Commissioner Nelson seconded by Commissioner Malecki to approve the minutes of the January 4 1 88 Y , 9 Planning Commission meeting as submitted. Voting in favor: Chairman Lucht, Commissioners Nlalecki, Nelson, Bernards. Voting against: none. Not voting: Commissioner Johnson. The motion passed. APPLICATION NO. 88001 (Metropolitan Transit Commission) Following the Chairman's explanation, the Secretary introduced the first item of business, a request for site plan and special use permit approval for a park and ride lot at the Brooklyn Center Church of the Nazarene, 501 73rd Avenue North. The Secretary reviewed the staff Y report (see Planning Commission Information Sheet for Application No. 88001 attached). The Secretary explained a public hearing is scheduled and notices have been sent to neighboring property owners. Commissioner Bernards asked if the original special use permit had any special conditions attached to it. The Secretary responded the special use permit was amended when the fellowship hall was added to the church in 1981 and future parking was discussed at that time. He stated that the church and fellowship hall are used at off -peak traffic hours and the church is used on evenings and weekends. He added that as far as he knows the church is in compliance with any conditions imposed with the last special use action. Commissioners Bernards inquired how the parking lot fits into the church's future plans. The Secretary stated the park and ride facility does not rule out future expansion for the church. Commissioner Johnson asked if and where a bus shelter would be located. A representive of MTC responded that a bus shelter would be built and located at the bus pickup point. 2 -11 -88 -1- Chairman Lucht called on the applicant to speak. Donald Shaffer of Barrientos and Associates, the architect for the applicant, explained the location of the lighting and stated that the light poles would be 30' high, rather than the 20' shown on the original plan. He stated he had just received a new plan that afternoon and was unable to inform the City before this evening's meeting. The reason for increasing the height of the poles is to get better distribution of light on the site. The Secretary asked if the design of the lights had been changed. Mr. Shaffer responded that the design is the same and there would be light shields on the residential side of the property. Commissioner Bernards asked if the lights are activated b a timer and at what time the first and last bus arrives. He also Y rr ves. asked if the lights are activated seven days a week. Mr. Shaffer responded that the lights would be activated by a timer and that he believed the lights would only be on five days a week. He added that he would have to check on this and what the time was that buses ran. Commissioner Nelson asked if the light poles are 30' high. Mr. Shaffer responded that there are nine poles 30' high; the reason for the higher poles is that they couldn't get enough illumination from the shorter poles. The Secretary asked the applicant to explain the bus schedule. Mr. Shaffer responded that he does not have enough information on the bus schedule, especially the Saturday schedule. Commissioner Bernards asked who is responsible for maintenance of the park and ride facility. Mr. Shaffer explained that there is a lease agreement being drawn up and at present, MTC is taking care of it. Commissioner Malecki asked if the facility is now being used as a park and ride facility. Mr. Shaffer responded that it is. The Secretary explained that it has been the City's position to encourage the use of existing facilities along bus routes for this park and ride use. He referred to the parking lot facility at Harron Methodist Church on 55th and Dupont Avenues North which is informally used as one. He stated he is not aware of any problems created with existing facilities of this kind. He noted the reason this application is before the Commission as a special use permit is because of the expansion of the existing lot for the park and ride facility. Y PUBLIC HEARING Chairman Lucht opened the meeting for a public hearing and asked if anyone present wished to speak regarding the application. Chester Nevin, 7242 Camden Avenue North, stated he was opposed to the facility and asked why this lot has to be expanded when other vacant property is available which does not affect residential property owners and could be used for such a facility. Mrs. Nevin stated she is also opposed to the ark and ride facility because she PP P Y believes it will have a negative affect on their property. Carol Carter, 7250 Camden Avenue North, asked why the property owners on the north side of 73rd Avenue North in Brooklyn Park were not notified of this evening's meeting. The Secretary explained that because those lots are in Brooklyn Park, the City notifies only the City of Brooklyn Park, who in turn may notify their Brooklyn Park residents. He added that even though those residents did not receive a notice, does not mean that they cannot comment on the project. 2 -11 -88 -2- Mrs. Carter stated she has added a $30,000 addition to her home and feels that the freeway expansion and now the proposed park and ride facility will devalue her property when the time arrives for her and her husband to sell their home. She stated she has contacted a real estate firm and was informed her property value would be downgraded a minimum of 5% of the market value. She explained she feels the facility will attract theft, breakins, littering and become an eyesore for the neighboring property owners to look at out their windows. She stated that she feels that the church has been parking cars in its parking lot illegally and also, it attracts kids to park there in summer. She asked why a facility could not be built at the neighboring vacant property near Beacon Bowl on 66th and West River Road which is not near any residential properties. She feels she and the rest of the neighbors have been very tolerant in the past and have never complained about any activities at the church. Chairman Lucht commented that nothing would change because of the proposed park and ride facility other than the addition of some parking stalls. Mrs. Carter stated she feels the view of the church parking lot, and now the park and ride facility, diminished the value of her property. Chairman Lucht asked if the church would be gaining income from the facility. Pastor Errol Webb of the Church of the Nazarene stated they are not receiving income from it now, but will have some type of lease agreement in the future. Jerry Cowan, owner of Evergreen Apartments which abuts the church parking lot to the south, stated he felt shrubbery is not acceptable screening as debris can blow into the apartment property more easily than through a fence. He stated he is also concerned with the height of the light poles which may allow light to shine into his tenants' apartments at night. Mr. Cowan also inquired if it would be possible to extend a sidewalk to his apartment complex to make access to the bus stop easier. Mrs. Carter asked why the City is agreeing to the expansion of the parking lot. The Secretary responded that the expansion is not a City- initiated project. He explained that MTC representatives approached the City and expressed the need for providing a park and ride facility location in this general area. He stated the City encourages the use of, or expansion of, existing facilities rather than build a new freestanding park and ride facility. The Secretary stated the property is still a church facility and the church will be responsible for maintaining its property. He noted that it just appears to be a more judicious use of property to expand an existing facility that is already convenient, than to build a new facility in the same general area. Mrs. Carter stated that she and the other property owners are the people who have to live with the results and the results include convenience and money for the church. The Secretary asked the MTC representatives to further explain the facility. An MTC representative explained that they had looked at other facilities in the area, but had decided the church lot to be more acceptable. Chairman Lucht asked what payment the church is getting for the park and ride facility. Mr. Shaffer responded that there will be a long term lease agreement drawn up involving maintenance and upkeep with some rental fee paid to the church. Chairman Lucht asked how long the lease agreement would be. Mr. Shaffer answered it would probably be a 20 year lease. 2 -11 -88 -3- Mr. Cowan asked if the land is tax exempt. The Secretary responded that the church is tax exempt and that MTC is a tax exempt entity. He added that he assumed the MTC use of the church lot for a park and ride facility would also be tax exempt. Mrs. Carter stated she still feels it is a moneymaker for the church. The Secretary stated the church will gain a better parking lot with improved drainage. Mrs. Nevin asked if there is one objection to the proposal would it be denied. The Secretary stated that it would not necessarily. He explained that this application is a special use permit and the standards for special use permits have to be addressed before it will be approved. He noted that these standards include that the use not be detrimental to public health, safety and welfare, not substantially diminish property values, not impede normal and orderly development, not cause traffic congestion and conform with pertinent development regulations. Mrs. Carter asked what the neighbors have to do to get the City to take another look at this project before approving it. The Secretary stated that the City has to balance the rights of all concerned. He explained that MTC park and ride lots are considered to be for the good of the public in that they help to reduce rush hour traffic congestion; serve to help reduce the consumption of gasoline, assist in lower (or maintaining) air quality standards; lessen the need for public expenditure of funds to build or upgrade new highway and freeway facilities. This must be balanced with the negative effects of the project on the neighboring property as outlined in the Standards for Special Use Permits. Chairman Lucht asked how much money anyone has lost. Mrs. Carter responded she believes she will lose approximately $20,000 when she sells her home. Chairman Lucht asked for clarification of location of the public property being referred to as a better location for the facility. Mrs. Carter responded that it is near the Beacon Bowl property on 66th and West River Road. Mrs. Nevin stated that when she looks out her window at peak traffic hours there is a life threatening situation created at the bus stop on T. H. 252. Six people have been killed previously in this area. Pastor Webb stated that the church's relocated entrance and driveway was moved further east than originally proposed to satisfy the neighbors. He explained that the church has tried to be a good neighbor and that he has picked up debris blown into the church's lot from the apartment buildings to the south. He stated the fence was taken down by the owner of the apartment complex. He noted that the church will continue to be a good neighbor and that he did not envision this parking lot expansion to be a detriment to surrounding property owners. Commissioner Bernards asked how long the church had been there. Pastor Webb responded that the church had been there 19 years. Chairman Lucht asked the neighbors what type of screening they would prefer. Mrs. Carter stated she would have to look at the fence and also, she now looks straight out to the freeway where all the garbage accumulates. CLOSE PUB HE U LIC ARING Motion by Commissioner Nelson seconded by Commission Malecki to close the public hearing. Voting in favor: Chairman Lucht, Commissioners Malecki, Nelson, Bernards and Johnson. Voting against: none. The motion passed. 2 -11 -88 -4- Further discussion ensued regarding the park and ride facility. Chairman Lucht polled the Commissioners for their opinion. Commissioner Nhlecki stated problems do exist and possibly the Commission should get further information before making a recommendation on the facility. Commissioner Nelson referred to the special use standards and stated he would would like to see the screening requirement addressed. He stated he does not believe that property values would be effected. Commissioner Bernards stated he would recommend MTC to work with the property owners on the screening requirement and to have proper maintenance and policing of the area. Commissioner Johnson stated he is concerned with the height of the light polies and recommended that other areas for location of the facility be looked at. Commissioner Malecki stated if there is no control over parking of 35 cars at present what will the impact be when there are 105 cars. She stated she would rather table the application and have further study done before making any recommendation. ACTION TABLING APPLICATION NO. 88001 (MTC) Motion by Commissioner Malecki seconded by Commissioner Johnson to table the application and direct staff to bring back further information on the following: - traffic impacts in this area if larger park and ride is established; -the MTC procedure for siting park and ride facilities; - effect on property values in the immediate area if the park and ride facility is located at the church; -any safety concerns associated with these facilities; - consideration of 20' high light poles rather than 30' high poles; the possibility of reducing the number of stalls to be located along the west portion of the property. Voting in favor: Commissioners ralecki and Johnson. Voting against: Chairman Lucht, Commissioners Bernards and Nelson. The motion failed. ACTION RECOMMENDING APPROVAL OF APPLICATION NO. 88001 (MTC) Nbtion by Commissioner Nelson seconded by Commissioner Bernards to recommend approval of Application No. 88001 subject to the following conditions: 1. Grading, drainage, and utility plans are subject to review and approval by the City Engineer prior to construction. 2. A site performance agreement and supporting financial guarantee (in an amount to be determined by the City Manager) shall be submitted prior to final approval of the plans. 3. B612 or B618 curb and gutter shall be provided around all parking and driving areas. 4. The applicant shall submit an as -built survey of the property, improvements and utility service lines, prior to release of the performance guarantee. 5. The property owner shall enter into the Easement and Agreement for Maintenance and Inspection of Utility and Storm Drainage Systems. 2 -11 -88 -5- 6. The proposed landscape screening or a 6' high opaque fence constitutes an acceptable screening device to be determined by the City Council. 7. The applicant is strongly urged to consider putting a light in the vicinity of the sidewalk linking the parking lot and the bus stop. Voting in favor: Chairman Lucht, Commissioners Nelson, and Bernards. Voting against: Commissioners Malecki and Johnson. The motion passed. DISCUSSION ITEM The Secretary reviewed proposed ordinance changes to Chapter 12, which is the City's Housing Maintenance and Occupancy Ordinance. He explained this ordinance is enforced by the Planning and Inspection Department. The Year 2000 Committee recommended consideration of extending the maintenance provisions of this ordinance to commercial and industrial property as well as residential. He asked the Commissioners to review the information included in their agenda packet for discussion at the Planning Commission study meeting on February 25, 1988. The Secretary explained that there will be other ordinance amendments to be discussed in the future such as parking of commercial vehicles and storage of boats, trailers and campers on residential property. ADJOURNMENT Motion by Commissioner Nelson seconded by Commissioner Bernards to adjourn the meeting of the Planning Commission. Voting in favor: Chairman Lucht, Commissioners Malecki, Nelson, Bernards and Johnson. Voting against: none. The motion passed unanimously. The Planning Commission adjourned at 9:32 p.m. Chairman 2 -11 -88 _6_ Planning Commission Information Sheet Application No. 88001 Applicant: Metropolitan Transit Commission Location: 501 73rd Avenue North Request: Site Plan /Special Use Permit Location /Use The applicant seeks site plan and special use permit approval to build a park and ride lot at the Church of the Nazarene at 501 73rd Avenue North. The property in question is the site of the Church of the Nazarene, is zoned Rl and is bounded on the north by 73rd Avenue North, on the east by Highway 252, on the south by the Evergreen Apartments, and on the west by a City well house and three single - family homes. Park and ride lots are not listed as a permitted or special use in any zone in the City. However, the lot is really accessory to the Church of the Nazarene which is an approved special use in the Rl district. Expansion of the parking lot is an amendment to the church's special use permit. Access /Parking Access to the site is gained via a driveway approximately 300' west of Highway 252. The access drive is not more than 24' wide and extends back some 150' to the parking area. The new parking lot will have 105 spaces, triple the present capacity of 35 spaces. ( The seating capacity of the church is approximately 100 persons and is not being enlarged at this time) . The parking lot is being expanded to the south and west of its present location. The parking expansion to the west will still be set back 105' from 73rd Avenue North. Buffer strips of 24' in width along the south property line and 15' along the west property line will be provided. A minimum 15' buffer strip is required when an office or apartment building is adjacent to R1 property. Staff feel that a 15' buffer is appropriate in the case of a church parking lot abutting other residential property. Landscaping A landscape plan has been submitted which indicates landscape screening within the westerly and southerly buffer strips. The screening would consist of American Cranberry shrubs planted 8' on center, interspersed with 4' high Black Hills Spruce. Under Section 35 -711 of the Zoning Ordinance, all open off - street parking areas having more than six parking spaces must be effectively screened from any abutting residential lots by a solid wall or opaque fence six feet high, or by such other device as may be approved by the City Council. Landscaping has been accepted in some cases, including the original church parking lot. The Commission should, in any action recommending approval, comment on the acceptability of the proposed landscape screening. In addition to the proposed screening, the landscape plan calls for nine (9) Cockspur Thorn shade trees along the west side of the entrance drive, to be planted 25' on center. The total number of landscape points represented by the plan is 210. Churches are not listed on the landscape schedule, but an office would be required to have 223 units on this site. Existing landscaping with the proposed plantings would meet that requirement. Grading, Drainage, and Utilities The grading plan calls for two new catch basins, one at the north end of the westerly parking area to be connected to City storm sewer in 73rd Avenue North, and one at the southeast corner of the lot to be connected to storm sewer in Highway 252. The City Engineer recommends that the top casting of the westerly catch basin be lowered • somewhat and using a 15" storm sewer pipe with a flatter slope. This would allow more effective drainage of the westerly portion of the parking lot. 2 -11 -88 -1- Application No. 88001 continued Lighting The site plan calls for nine light poles 20' high with 250 watt high pressure sodium luminaires. Under Section 35 -712 of the Zoning Ordinance, the illumination from parking lot lighting is not to exceed three foot candles at property lines abutting residentially zoned property. The applicant's engineer, Barrientos and Associates, has submitted partial information on the lighting which assumes no back lighting from the luminaires. The light fixtures do focus the light downward and side shields will be provided on those light poles adjacent to residential property. The proposed lighting should, therefore, comply with ordinance standards. Other Items The proposed site plan calls for a 6' wide sidewalk to be installed from the existing drive -up circle east of the church to the MTC pick -up location on Highway 252. The City currently plows the sidewalk on 73rd Avenue North and will plow this walk as well. There is also a driveway planned from the southwest corner of the lot to the City's well house property. This is to allow a rear access for City vehicles to the well house. It can be used as a parking space most days. The City will post it no parking on days when access is needed. Recommendation Altogether, the plans appear to be in order and approval is recommended, subject to at least the following conditions: 1. Grading, drainage, and utility plans are subject to review and approval by the City Engineer prior to construction. 2. A site performance agreement and supporting financial guarantee (in an amount to be determined by the City Manager) shall be submitted prior to final approval of the plans. 3. B612 or B618 curb and gutter shall be provided around all parking and driving areas. 4. The applicant shall submit an as -built survey of the property, improvements and utility service lines, prior to release of the performance guarantee. 5. The property owner shall enter into the Easement and Agreement for Maintenance and Inspection of Utility and Storm Drainage Systems. 6. The proposed landscape screening constitutes an acceptable screening device in lieu of a 6' high opaque fence. 7. The applicant is strongly urged to consider putting a light in the vicinity of the sidewalk linking the parking lot and the bus stop. 2 -11 -88 -2- CITY OF BROOKLYN CENTER council mtg date 2/ 22/88 + agenda item no.

Y�kdr�Y�rdr�r�c�e�' r�' e�Y�r�Y�r�'c *u�YsYsYsYsY�r�rx�Y SUMMARY EXPLANATION: (supplemental sheets attached Yes) Explanation: For many years, residents in the West Central area of the City have reported problems with the quality of the water which is delivered to their homes from the City's water supply system. The attached report documents the actions taken during the past five years to develop a " low cost" solution (i.e. one based on operation and maintenance procedures, rather than on replacement of the unlined cast iron pipes which are the basic cause of the problem). The City's current program consists of: (1) using chemicals for corrosion control; (2) operating three in -line pumps to induce circulation of water in that part of the system; (3) flushing watermains in those areas where this has been shown to be effective; and (4) offering individual assistance to property owners who experience specific problems. It is the opinion of City staff that this program is the most effective one which can be developed using the operation and maintenance approach. If the quality of the water now being delivered is considered unacceptable, the report recommends initiation of water main replacement program, provides cost estimates for such a program, and suggests development of a process and a policy under which such improvements can be initiated. Action required by Council: Review and discussion of the report, followed by direction to the staff regarding development of a public information program, and formalization of the City's policies and procedures regarding this matter. If a replacement program is to be initiated during 1988, the report outlines a schedule for implementation of such program. t TO: Gerald G. Splinter, City Manager FROM: Sy Knapp, Director of Public Works DATE: February 16, 1988 RE: Water Quality Improvements In West Central Neighborhood - Status Update History For many years, residents in the West Central area of the City have reported problems with the quality of the water which is delivered to their homes from the City's water supply system. During the past 5 years extensive investigations have been conducted, numerous "remedies" have been attempted, and extensive monitoring has been done to examine the effectiveness of those measures. Documentation regarding the City's efforts during the past 5 years is contained in the appendices attached hereto: Appendix A - copies of all staff reports covering this subject between October, 1983 and the present Appendix B - copies of reports covering the subject, as prepared by Serco Laboratories, during 1986 and 1987 Appendix C - maps showing the pattern of water quality complaints received from this neighborhood. A review of materials contained within individual reports in those appendices will occasionally contain apparently conflicting statements. (Example: An early report may recommend in -line chlorination, while a later report recommends that in -line chlorination be discontinued - after detailed testing showed short - term benefits but detrimental long -term effects.) However, I believe that when taken in total, this material demonstrates that a very serious effort has been made to deal responsibly with a very difficult and perplexing problem, and to identify cost - effective solutions. w A Current Evaluation As described in my 10/14/83 memo, the basic problem is the result of 3 factors: 1. Poor Circulation The location of this neighborhood within the City's distribution system is such that there are no trunk lines which flow through the area, creating a condition called a "hydraulic dead end" wherein there is little movement of the water in the mains. 2. Small Diameter Mains All mains in the area are of small diameter - and there are some dead -end mains. 3. Unlined Cast Iron Pipe Most, if not all of the water main pipes in this neighborhood are unlined cast -iron pipes, installed in the mid -to -late 50's. Unfortunately, no documentation has been found to demonstrate which mains are lined and which are unlined. However, all samples examined during the past 5 years have been found to be unlined pipe. As noted above, and in the attached appendices, numerous attempts have been made to find a "low cost" alternative (i.e. one which does not involve the high costs of replacing the water mains). Following is a summary of those attempts, our current evaluation of each action, and its current status.

This includes problems. in resolving a specific flushing out service lines problem. with the use of quick - acting valves, and providing technical advice for homeowners regarding in -house problems. In summary, our current "answer" to controlling the problem consists of (1) adding zinc orthophosphates to the water supply; (2) operating the 3 in -line pumps within the neighborhood on a continuous basis; (3) flushing water mains in those areas where this has been shown to be effective; and (4) offering individual assistance to property owners who experience specific problems. The net effect of our current program is a substantial improvement of "normal" quality of the water which is delivered to homes in this area, as measured by (1) lower levels of iron; and (2) maintenance of chlorine residuals. These effects are the result of our ability to maintain a zinc concentration at 1.0 m L thereby hereby providin g a thin coatin g on the corroded walls of the water main. pipes and minimizing further corrosion. However, while the "normal" water quality has been improved by those measures, the following comments are noted: 1. The costs for use of zinc orthophosphate is estimated to be approximately $60,000 per year. 2. The cost of operating and maintaining the in -line pumps, flushing mains flushing house servic estimated � c s etc is imate d to be g , approximately $10,000 per year. 3. During the past 3 years the cost of staff time and consulting services (by Serco Laboratories) has been approximately $50,000 (total). 4. While "normal" water quality has improved, some property owners continue to report that their water quality is unacceptable on a continuous basis, while others report occasional problems. c v 5. As stated by Serco Laboratories in their "Observations and Comments" dated November, 1987, "... the corrosion control procedure using chemical coating of the unlined water mains is very fragile...." And ...... Once the protective zinc orthophosphate coating is removed (because of some disturbance of the system) it takes time to replace the coating so that it become effective again. All of this report to this point describes our efforts, our failures, and our successes in attempting to developea "low- cost" solution to the problem. It is my opinion that our current program (with minor adjustments) is the most effective one which can be developed using the operation and maintenance approach. If the quality of the water now being delivered to homes in this area is considered unacceptable, I recommend that a program to start replacing the unlined water mains in this area be considered. Water Main Replacement Program All of the work completed during the past 5 years has served to reinforce the conclusion that the principal problem derives from the fact that the water main pipes serving the neighborhood are unlined cast iron pipes. Over the period of the past 30 years, substantial corrosion has occurred, building up a substantial deposit of ferrous oxide (rust) within the system. Unless the deposit can be stabilized, (utilizing operation and maintenance procedures now being used) or permanently contained (see next paragraph), it will continue to cause problems. Several methods are offered within the industry for "permanent containment" of the corrosion problem. These include (1) cleaning and cement lining the existing water mains in place; and (2) various methods for installing other types of liners into the existing mains. Our review of available information regarding these methods indicates that (1) none are as reliable as the replacement alternative; (2) most of the other methods are more suitable for larger diameter pipes; and (3) the cost of these alternatives range between 50% and 100% of the cost of the replacement alternatives. Therefore, I recommend against consideration of any of the methods. Accordingly we have developed cost estimates for initiation of a water main replacement program. As previously noted, no records exist which can define the limits of the area served by unlined cast iron water mains. However, on Exhibit No. 1 we have outlined the larger neighborhood area from which more water quality problems are reported than for any other similar -sized neighborhood within the City. It is probable that most, if not all, of the water mains in this neighborhood are unlined cast iron mains. ( Notes: Because other areas of the city were also developed during the same period, it is probable that there are a number of z other unlined cast iron mains in place in those areas also. However, the problems there have not been as concentrated because (1) the condition is not as homogenous as it is in the West Central Neighborhood; and (2) their location within the distribution system assures nearly continuous flow thru that portion of the system). For the purpose of "getting a look at the larger picture" we have developed an estimate (see Exhibit No. 2) of the costs for replacing all water mains within the area defined on Exhibit No. 1. That total cost estimate (see Exhibit No. 2) is $2,658,320. Although we are not recommending this total program at this time, and it is probable that not all of this program will ever be completed, it should be regarded as a possible scenario. Based on our experience, and based on customer complaints, the specific portion of the larger neighborhood which experiences the worst problems is the area from Quail Avenue North to Unity Avenue North, between 63rd Avenue and 65th Avenue North (see Exhibit No. 3). It is my recommendation that, if a water main replacement program is initiated, the first phase of that program should include all mains within this area. As shown in Exhibit No. 4 the estimated total cost for replacing all mains within this area is $666,270. Recommendations For Initiation of And Funding For Water Main Replacement Program If the City Council is receptive to the concept of initiating a water main replacement program, I recommend that the Council approve a process by which to proceed. The first element of that process should be the adoption of a cost - sharing policy, while the second element should be a determination of whether specific improvements will be initiated by City Council action or by petition of the property owners. In considering the matter of establishing a cost - sharing policy, the following observations are noted: 1. The existing water mains within this area have an average age of approximately 30 years. 2. Most cities consider the "life expectancy" of water mains to be 40 to 50 years. However, it is noted that many water mains remain in service well beyond those life expectancies. 3. If special assessments are to be levied to cover a portion of the costs for replacing water mains, the City Council may do so only after concluding that the value of the properties served will be increased at least equal to the amount of the special assessment. 4. If the project is constructed under Chapter 429 of the Minnesota Statutes, the City may not issue "full faith and credit improvement bonds" covering the City's portion of the costs unless at least 20% of the total cost of the improvement is defrayed by special assessments. 5. If a project is initiated by a petition of 35 percent of the affected property owners, the City Council, following a public hearing on the proposed improvement, may order the project by adoption of a resolution with a simple majority vote of the City Council. 6. If a project is initiated by a petition of less than 35 percent of the affected property owners, or if it is initiated by action of the City Council, the Council may order the project only by adoption of a resolution with a 4/5 the vote of the City Council following a public hearing on the proposed improvement. After consideration of this matter, I recommend that the City Council (1) adopt a policy which provides for the special assessment of at least 35% of the cost for any water main replacement within this area; and (2) adopt a policy that all water main replacement projects must be initiated by petition of the property owners but without a pre- determination as to the percentage of owners who must sign such petition before formal proceedings are commenced by the City Council. This recommendation is based on the fact that a number of complainants have reported loss of property value and /or difficulty in selling their homes because of the water quality problem. Although those statements may not provide . conclusive evidence that replacement of the mains would increase property values, I believe they provide considerable evidence for reaching that conclusion. In addition, if property owners are willing to sign a petition requesting the improvement, with full knowledge of the City's policy regarding cost - sharing, I believe the City's ability to sustain special assessments would be well established. As noted above, I recommend that the City Council not pre- determine the percentage of signers required before commencing formal proceedings. Rather, I recommend that interested parties be directed to obtain as many signatures as possible on their petition(s), then present their case to the City Council. Then, if the City Council decides to conduct an improvement hearing, it may also decide to conduct a concurrent "Special Assessment" hearing, with the intent of finalizing the special assessment proceedings before proceeding with construction of the project. By this process the Council can insure the City against a reversal of special assessment levies. To establish an equitable assessment rate which would be applicable to the replacement of any portion(s) of the water main system, we recommend consideration of the following formula: Total Cost for Replacing all water mains in the area shown in Exhibit No. l ($2,658,320) x 0.35 = $1661 /home Total number of homes served within that area (560) If the City Council considers this to be appropriate, I recommend that an "estimated assessment rate" for any water main replacement during 1988 be established at $1661 per single family lot. Exhibit 5 we have shown the annual payments resulting from a special assessment levy of $1661, assuming a 20 year payment period, and assuming a 10% interest rate. Public Information Program This item is scheduled for presentation to the City Council as a "Discussion Item" at their February 22, 1988 meeting. Following initial discussion of the matter, I recommend that staff receive direction from the City Council regarding the matter of informing property owners in the affected area of the status of our program and obtaining public input. The following options are suggested for consideration: sending copies of the report to all property owners (this basic cover report without the appendices - the appendices can be "available for public review" to anyone interested) - City staff conduct informational meeting after sending notice of the meeting to all property owners - City Council schedule this as a "Discussion Item" at a subsequent meeting, with instructions to staff to send notices of that meeting to all property owners. - Any combination of the above. Schedule Following is a preliminary schedule of events and proceedings which could allow installation of some improvements during 1988.

If the action can be completed at the 3/28/88 Council meeting, the remaining schedule should be advanced approximately 2 weeks. • Conclusion and Final Comments It is our opinion that the City's current operation and maintenance program is the most effective program which can be developed for the purpose of controlling water quality in the West Central Neighborhood. If the water quality is still unacceptable, a program to replace the unlined cast iron pipe with cement -lined ductile iron pipe should be initiated. This report has outlined a feasible basis for initiating such a program. The following comments omments or caveats need to be stated to assure realistic expectations: 1. Replacement of unlined water mains with lined water mains on a block - by -block or small -area basis will not be as effective as a replacement program covering a larger area. This is due to the fact that the products of corrosion from one area do "migrate" into adjacent areas. While we would not expect this to be a major problem, the possibility of this occurrence must be recognized. S I ;t 2. Even if all unlined pipes were replaced with lined pipes, some residents would still experience some water quality problems, due to the existing accumulation of the products of corrosion in the service lines to the houses and in the internal plumbing systems of the houses. However, those problems should be significantly smaller than the ones now being experienced. 3. The City must expect to continue providing chemical treatment of its water supply for the purpose of providing corrosion control. The use of zinc orthophosphates (or zinc polyphosphates) should not be discontinued until and unless all of the unlined pipes are replaced with lined pipes. On this basis, the City must expect to continue spending approximately $60,000 /year (based on current prices) for use of those chemicals. 4. If all unlined pipes are ever replaced with lined pipes, the City should consider switching to the use of polyphosphates (without zinc). This would reduce the cost of chemicals from $60,000 /year to $25,000 /year. 5. If a water main replacement program is initiated, the Council and /or property owners may also wish to consider installation of concrete curb and gutter in the streets in this area in conjunction with the water main improvements. On the basis of the City's current policies, this option would be available to property owners at a cost of $1325.00 per lot. If a small amount of curb and gutter were to be included, this could be included in a 1988 program. However, if a large amount of street improvements were to be added to a watermain replacement program, the total program would have to be extended into 1989. Undoubtedly, the City Council, the property owners, and residents will wish to ask many questions and provide input into this matter. That is as it should be. This report is provided as a basis for those discussions.

Splinter, City Manager FROM: Sy Knapp, Director of Public Works DATE: October 14, 1983 RE: Water Quality Problems This report is intended to describe the extent and severity of the water quality problems, to define the causes of the problems, to summarize corrective actions which have been taken to -date, and to discuss other available options. Water Quality Summary Following is a summary of the chemical characteristics of the ground water supply as obtained from the City's 8 Jordan aquifer wells Brooklyn Center Normal Characteristic Wells Standard Total Iron, mg /L .05 to .10 0.30 (1) Manganese, mg /L 0.2 to 0.4 0.05 (1) Total Hardness, mg /L 320 to 370 None (2) pH 7.3 to 8.0 6.5 to 8.5 Corrosivity High - -- The following comments are quoted from the 1983 Black and Veatch study of our Water System. (1) Re: "IRON AND MANGANESE. The maximum concentrations for iron and manganese under the USEPA Secondary Standards are 0.3 mg /l and 0.05 mg /1, respectively. Greater concentrations are objectionable because of the insoluble red and black compounds which are formed within the water upon chlorination, aeration, or other means of oxidation. These compounds cause staining of plumbing fixtures, spotting of laundered clothes, and accumulation of deposits in distribution systems. Because of the chlorine demand and presence of turbidity caused by the reaction, disinfection and maintenance of a chlorine residual within the distribution system is subject to interference. "Ile 564a&lia nau eze� ,• October 14, 1983 - G.G. Splinter Page 2 Additionally, the presence of iron and manganese may result in the growth of slime forming "iron bacteria ", which can cause a chlorine demand, and result in taste and odor problems in the distribution system. All seven existing wells have manganese concentrations well above the recommended limits. Although the iron concentrations for all existing City wells are below the recommended limits, the general water quality associated with the Jordan aquifer indicates high iron concentrations may be a problem in the future." (2) Re: "HARDNESS. Water hardness is measured as the concentration of divalent metallic ions, principally calcium and magnesium. The requirements for soap and detergents are directly related to water hardness. f 0 particular importance is the tendency or development Y P of scale due to hardness when water is heated. This scale shortens the useful life of water heaters, pipes, and fixtures. There are no applicable regulatory standards for hardness at this time. Acceptable levels of hardness are generally based on economics and consumer preference. A hardness of 200 to 250 mg /l may be acceptable for some areas where home water softeners are used to suit individual preference. For hardness levels above 300 to 350 mg /1, treatment of the water supplied to the distribution system is generally recommended. The total hardness for the existing well field exceeds 300 mg /l which indicates treatment for softening should be considered." From the above, it would appear that our major problems should be caused by the high level of manganese and by the hardness of the water. In fact, our experience does indicate a number of "black- water" complaints throughout the City (indicating the high manganese level). However, nearly all of these problems occur only in hot water and can almost always be corrected by regular flushing of the water heaters. No other serious problems appear to be attributable to manganese. Regarding the high level of hardness, this is a "fact-of-life" which most Brooklyn Center residents have seemed to accept and cope with by the use of water softeners. We estimate that at least 95/ of all homes in Brooklyn Center are using water softeners. In addition to the manganese - related complaints and the hardness problem, we also receive a number of taste and odor complaints. These are usuall Y related to one or more of the th o er complaints i.e. red or black water, hardness, t etc. . October 14, 1983 - G.G. Splinter Page 3 Most red - water, black - water, hardness and taste - and -odor problems could be eliminated by construction and operation of a water treatment plant. However, a 1980 study by Black and Veatch indicated that the costs to construct a water treatment plant would be approximately $13 million (1980 cost). Because the total costs (for capitalization of this invest- ment and for operation and maintenance of the plant) would require increasing water rates to approximately 5 times the present rate, the City Council has previously ruled out the construction of a treatment plant. Severe Problem Area During the past 3 years an effort has been made to maintain better records of citizen complaints regarding water quality. During this time it has become obvious that there is one area in the City where the water quality problems are substantially more severe than in the rest of the City. This is the area West of Noble Avenue, between 61st Avenue and I -94. Within this area, we receive more black -water and taste - and -odor complaints than from any other comparable sized area within the City. In addition, many red -water complaints (which are relatively rare throughout the rest of the City - as should be expected from the low iron levels at the wells) are received from residents within this area. A detailed review of the water distribution system serving this area shows the following factors which appear to contribute to the concentration of problems within this area: 1. The location of the area within the distribution system is such that no trunk lines flow through the area. As a result, the entire network in this area has no continuous flow. 2. Most mains within the area are 4 ", 6" or 8" in diameter - and there area some dead -end mains within the area. 3. Several samples of water main pipe taken from the system within the area indicate that these mains are "unlined" cast -iron pipe. Our current standards call for any new water mains to be lined with a cement - mortar lining, to prevent corrosion from occurring within the mains. Construction documents and records for pipe used in this area do not indicate whether the pipe used here was lined or unlined. However, the samples tested, and other informa- tion lead us to believe that none of the pipe in this area was lined. Chemical testing of water samples taken from within this area in the summer of 1983 shows the following: Characteristic Area Samples Total Iron 0.20 to 4.50 Manganese 0.15 to 0.36 Total Hardness 320 to 350 pH 7.1 to 7.2 October 14, 1983 - G.G. Splinter Page 4 These tests indicate that while the other characteristics of water in this portion of the distribution system essentially retain the same levels that are found at the wells, the iron concentration has risen dramatically. The only apparent conclusion that can be reached is that corrosion is occurring within the unlined mains in this area and are concentrating here due to the lack of circulation within the system. Corrective Actions Taken In 1982 During 1982 the Public Utility Department attempted to correct the problem by: 1. flushing mains and hydrants within the problem area 2. superchlorinating particularly troublesome sections of main, then flushing these mains; and 3. introducing a sequestering agent (sodium polyphosphate) into the water supply at our wells. Sequestering agents do not remove metallic ions from solution, rather, they are supposed to tie them up to help prevent accumulation and precipitation of deposits. Unfortunately, the positive results of these efforts were minimal and short- lived. Corrective Actions Taken In 1983 During 1983 the following actions have been taken: 1. changed to the use of a "film forming" chemical inhibitor (zinc orthophosphate) in lieu of the sequestering agent. The concept behind this chemical is that when it is continuously added to the water supply, it will form a very thin protective coating of zinc on all surfaces within the distribution system. This film tends to inhibit the metallic corrosion - thereby reducing the red -water problem. 2. all mains within the problem area have been flushed at least twice, some 3 times. 3. the amount of chlorine fed into the water supply has been increased to assure that a "chlorine residual" is maintained throughout the system to prevent the growth of iron bacteria within the system. 4. extensive testing has been accomplished (see discussion above) 5. additional testing is being done in order to monitor the results of the chemical inhibitor. This includes the installation of 3 manholes within the problem area to allow access for monitoring "test coupons" inserted into the mains, to test the effectiveness of chemical inhibitors. October 14, 1983 - G.G. Splinter a Page 5 Although we are unsure how effective these measures will prove, we are cautiously optimistic that they will produce a measureable improvement of water quality within the problem area. We realize that some problems will continue to occur. However, at this point we hope to keep them at a tolerable level without major capital investment. Other Options Other possible solutions for this problem area have been considered. These include the following: 1. Other Chemical Treatment Comment: We are continuing to review other chemical inhibitors. However, we feel they must be tested one -at -a -time, over a consid- erable period, in order to allow a meaningful evaluation. Despite the assistance provided by the City of Minneapolis, Black and Veatch and Serco Laboratories, to -date we have not been able to identify any other chemical which has any more promise than the zinc orthophosphate. 2. Installation of "In- Line" Pumps Within the System in the Problem Area Comment: This appears to offer some hope. However, a detailed hydraulic analysis is needed to determine whether an in -line pump would be effective for more than one or two blocks. 3. Cement - Lining of Inplace Water Mains Comment: This is a possible, but expensive solution. Estimated costs are $35.00 per foot. With more than 30,000 feet of pipe within the problem area, the costs could reach more than $1.0 million. Even with this kind of investment, the problem might still not be eliminated because: a) cement lining of small- diameter pipe is difficult and has some history of failure. b) we are uncertain as to the exact limits and origin of the problem. It is possible that corrosion could occur in areas outside of the project area in which the pipe is lined, then have the red -water problem "migrate" into the newly lined mains. 4. Replacement of Old Mains Comment: This is even more expensive than cement lining the inplace mains. With an estimated cost of $50.00 per foot, the total cost could exceed $1.5 million. Obviously, by installing new cement - lined pipe the problem of in -line corrosion would be eliminated. However, the possibility of migration from adjacent areas would still exist. October 14, 1983 - G.G. Splinter Page 6 Summary and Recommendations While the problems noted are frustrating for City officials - and much more so for the citizens within the problem area - it must be noted that the problem is an esthetic one - not a health problem. If either of the two high -cost options (cement - lining or replacement) are selected, it is obvious that the City would have to levy special assessments to recover a major share of the costs. Such assessments would undoubtedly be objectionable to a high percentage of residents in the area (some of whom report no problems). Accordingly, I recommend that the City continue to use and monitor the low -cost options which we have initiated. As noted above, we are cautiously optimistic that an acceptable level of service can be attained without extensive capital improvements. Respectfully submitted, SK: jn TO: Sy Knapp, , Director of Public Works A _ FROM: Jim Grube, City Engineer..,= DATE: April 2, 1984 RE: Water Quality Review in Westerly Neighborhood South of I -94 At your direction, I am providing a summary of the research completed to date on the subject of water quality problems in the City's westerly neighborhood, south of I -94. Prior History Department records indicate the staff acknowledged the existence of water quality problems within the neighborhood in 1973. At that time staff considered the problems to be the result of an hydraulic dead end. Staff experimented within the neighbor- hood by valving various mains to induce water flow through the system. This was considered to be a short term program that could be abandoned upon completion of water main installation along 66th Avenue from Brooklyn Boulevard to Noble Avenue and along 67th Avenue from Noble Avenue to Quail Avenue. Department records do not indicate whether the valving experiment continued after the referenced water main extensions (I assume it did not). Current Position The City has installed two manholes over water main within the neighborhood at 6407 Regent Avenue and 6425 Unity Avenue. Steel coupons will be placed in the main for corrosivity testing during the week of April 2, 1984. Based upon water quality testing undertaken between October 1983, and March 1984, (see attached) staff visited residences at 5113 Paul Drive and 6413 Regent Avenue, taking water samples directly from eater service leads into the home at the meter (March 29 , 1984). It was found that the water entering the homes had negligible residual chlorine and had an odor attributable to the presence of iron bacteria. Accordingly, Public Utility personnel flushed two hydrants in the area (one at Eleanor Lane and Regent Avenue and one at Paul Circle) to circulate water through Paul Drive and Regent Avenue. At this time the system has been valved off to induce water flow through Paul Drive and Regent Avenue (see attached). This flow direction has been assured by the opening of the hydrant at Eleanor Lane and Regent Avenue and the bypass of the water directly into the City's storm sewer. A second inspection of the listed Paul Drive and Regent Avenue addresses is scheduled for the week of April 2, 1984, in anticipation of finding residual chlorine in the area. Proposed Continued Research If it is found that the main valving described above (see attached) successfully induces the flow of "fresh" water through the Paul Drive - Regent Avenue neighborhood, it is recommended the City install a positive displacement chemical feed pump in the manhole at 6407 Regent Avenue. The pump would inject liquid zinc orthophosphate into the system (film forming agent) in an effort to reduce the activity of the iron bacteria. Presently, the residual zinc concentration is 0.2 ppm ±, while E.P.A. regulations allow 5 ppm. Therefore, point source application at this point could be undertaken with little fear of "over- concentration ". The chemical feed pump could be regulated by use of a time meter to insure that it would not needlessly operate 24 hours per day. April 2, 1984 - Water Quality Page 2 If the ro osed chemical feed t this 1 1 p p system �s successful on is sma 1 scale (as measure d over a one month period), the pump could be moved to the manhole at 6425 Unity Avenue and a localized "pilot study" could be carried out along Unity Avenue, Eleanor Lane and Scott Avenue. Again, after a one month period, water samples could be taken to determine the chemical's effect on the water quality within the neighborhood. If the pilot studies prove successful, the City could investigate the feasibility of placing an in -line pump within the Unity Avenue -Howe Lane intersection in conjunc- tion with the throttling of strategic valves within the neighborhood to produce artificial pressure differentials throughout the system (resulting in water flow to equalize the pressure differential). Absent any comment from you, the staff will continue with the inducement of water flow in the Regent Avenue neighborhood that was begun the week of March 26th.

Splinter, City Manager FROM: Sy Knapp, Director of Public Works DATE: September 7, 1984 RE: Water Quality Problems in West /Southwest Neighborhood. During the past year, we have continued to spend considerable time and effort in monitoring water quality problems as they occur within the system, responding to citizen complaints and inquiries, and attempting to develop feasible solutions. Our observations and evaluations may be summarized as follows: 1 - Because of the high concentration of manganese which occurs naturally in our water supply, we receive a number of "black water" and taste and odor complaints from throughout the City. Nearly all of these problems occur only in the hot water and can almost always be corrected by regular flushing and correct temperature controls of the water heaters. Elimination of these problems could only be accomplished by the construction of a very costly treatment plant. 2 - Because of the high level of hardness which also occurs naturally in our water supply, it is necessary for most customers to have water softeners. Improper operation or failure of water softeners also result in complaints regarding - P water quality articular) g g q Y particularly taste and odor complaints. Again, these problems occur randomly throughout the City and could be eliminated only by the construction of a very costly treatment plant. A 1980 report by our consultants (Black and Veatch) estimated the costs for such a plant at $13 million (1980 costs). 3 - During the past several years, we have concentrated on one area of the City in which the most severe water quality problems exist. This is the area between Orchard and Unity Avenues, between 63rd and 65th Avenues. Gerald G. Splinter, City Manager -2- September 7, 1984 F Within this area, we receive more black water and taste and odor complaints than from any other comparable sized area of the City. Many red water complaints (which are relatively rare throughout the rest of the City, as should be expected from the low iron levels at the wells) are received from residents within this area. 4 - Chemical testing in the problem area shows that, under normal operating conditions, the water within the system shows the following symptoms: (a) a lower than normal chlorine residual (b) a lower than normal residual of zinc orthophosphate (a chemical which is needed to inhibit metallic corrosion in the system); and (c) iron levels which are higher than those found in the water at the wells. All of these symptoms indicate that corrosion is occurring within the water mains in this area. 5 - Hydraulic analyses of the water system also indicate that this portion of the system operates as a "hydraulic dead - end ", i.e. water tends to stand or move very slowly. 6 - During 1984, we have conducted experiments at two locations within this problem area. During these experiments, we have: (a) created artificial flow conditions by closing certain valves and running water through fire hydrants directly to a storm sewer; and /or (b) added a chemical inhibotor to the water within the problem area. In all cases, residents reported improved water quality while the experiments were in progress and our chemical testing showed improved levels of chlorine and zinc, while showing reduced iron levels. Also, in all cases, residents reported a deterioration of water quality within two weeks after termination of the experiments. Our chemical testing confirmed the deterioration. Recommendation: Based on our observations and experiments, we recommend the installation of permanent in -line pumps and chemical feed equipment at three locations within the problem area, (one in the 6300 block of Orchard Avenue, one in the 6400 block of Regent Avenue, and one in the 6400 block of Unity Avenue). The estimated total cost for the three installations is $11,000 and the estimated operational costs are $1,000 per year. We recommend that these costs be charged to the Public Utility Fund. While we know this will not eliminate all problems, we are confident that it would reduce the problems within thi small pr oblem area by 75 to 90 per cent. y Gerald G. Splinter, City Manager -3- September 7, 1984 Immediately adjacent areas suffer some of these same problems, but to a somewhat lesser extent. If this proposed solution does help to resolve the problems in the area in question, similar action should be considered in these other areas - on an individual basis, as the severity of the problem is demonstrated. If approval is granted by the City Council, these installations can be completed and placed in operation within the next two months.

Spurrier, City Engineer DATE: June 24, 1986 RE: Water Quality Improvement Project No. 1986 -18 In an effort to improve water quality, three circulating pumps were temporarily installed in 1984 at three locations in the West part of Brooklyn Center between 65th and 63rd Avenues. These installations were at Unity Avenue, Regent Avenue and Orchard Avenue. The purpose of the installation was to maintain a chlorine residual so as to improve water quality in this area by circulating the flow in the water mains. Circulation alone did not maintain a sufficient chlorine residual and so supplemental chlorine addition was incorporated in one of the installations. During the past two years the circulating pumps and supplemental chlorine additions have improved water quality in our distribution system by successfully maintaining a residual of chlorine in the water supply. Because of the success of this experiment we plan to install a permanent in -line booster pumps to circulate the flow dependably. A different pump system must be _ used because the existing temporary installations are subject to damage from high water table and damage from accumulated heat. By utilizing a different pump system there is no buildup of heat and no threat of damage from high water table. We have received quotations for the pumps and we have received quotations for the construction of vaults in which the pumps will be installed. The two bids for the booster pumps are as follows: 1. Tri -State Pump and Control — $2,486.00 per pump Total — $ 7,458.00 2. Keys Well Drilling Company — $4,317.56 per pump Total — $12,952.68 By a considerable margin Tri -State Pump and Control submitted the lowest quotation and it is recommended that we accept their proposal. We have received quotations for the installation of the pumps and vaults for the three locations. Those quotations are as follows: „ '7lcc So•�cttici.rg 91L �� „ / 1 July 24, 1116 Page 2 Bidder Bid Amount Hank Weidema Excavating $ 8,540.00 0 & P Contracting, Inc. 21,500.00 Kirkwold Construction 26,500.00 Hank Weidema Excavating has supplied the low quotation for the installation of pumps and vaults. It is obvious that there is a very great difference between the low bidder and the other two. It is our opinion that the bid submitted by Hank Weidema is a responsible bid and that he has full understanding of the project requirements. The high prices submitted by the other two bidders reflects the fact that there is much work available. In fact, a fourth contractor who was asked to bid declined to do so because he is unable to handle any additional work. Accordingly, it recommended that the City accept the proposal of Hank Weidema Excavating. It is my recommendation that City Council adopt the attached resolution authorizing the acceptance of the proposals as described above to make the recommended water quality improvements. It is noted that, despite the work accomplished to date, and the additional work recommended herein, citizens within this neighborhood have continued, and will continue, to experience some problems with water quality. however, it is our opinion that s4gnificant improvements have occurred and that the current proposed work will insure that this level of improvement will be sustained. In the meanwhile, the Public Utility Division is continuing to work with the residents, with plumbers, and with engineering testing laboratories to develop additional, cost effective solutions to the problem.

Berg, 6333 Regent Avenue North. (It is my understanding that Ms. Berg sent copies of her response to all Councilmembers.) As noted in previous reports to the Council, the area in which this specific problem occurs is the area west of Noble Avenue between 61st Avenue and I94. Within that neighborhood, the most severe problems are reported in the area west of Perry Avenue between 63rd and 65th Avenues North. Extensive analysis and investigation has shown that the water quality problems experienced by the residents are caused primarily by two factors: i.e. (1) this area is a hydraulic dead end within the City's water distribution system and (2) the water main pipes in this area are unlined cast iron pipes. Either one of these factors would normally not cause the type of problem which is being experienced. However, the two factors operating together have created the problem. In a 1983 report to you we noted that the estimated cost for replacing all of the water mains within the larger problem area would cost an estimated 1.5 million dollars. In addition, we noted that replacement of all water mains within the area would not necessarily resolve the problem since two additional factors could result in new roblems i.e. 1 the possibility of mi ration from ( ) • P y g m ad'acent areas would still 11 exist and (2) much of the material which is causing the problem has already built up within the individual plumbing systems of the residences in the area. Accordingly, we recommended in 1983 that the City continue to use and monitor low cost options in an effort to find a cost effective solution. During the past three years we have implemented, tested and monitored the following "low cost" options: •• Ilse .So.rsetlCiacq. mau (� •• i August 22, 1986 Page 2 1. chemical treatment of the water supply 2. flushing and superchlorination of water mains within the problem area 3. installation of in -line pumps and an in -line chlorination station within the problem area. After monitoring each of these options it is our opinion that: 1. Chemical treatment of the water supply has a very limited effect within the problem area. 2. Flushing and /or superchlorination of water mains within the problem area does provide substantial improvement of water quality for a very short time. However, within one or two weeks following this action the water quality again deteriorates. 3. Operation of the in -line pumps and in -line chlorination station appears to have stabilized the water quality within the City's water main system. This is demonstrated by our ability to successfully maintain a residual of chlorine. Because of the success of this option we will install permanent in -line pumps and chlorination system this fall. However, this is at best a partial solution. Additional answers must be found to achieve an acceptable level of service to the homeowners in this area. To find those answers, the Public Utility Department is currently conducting a survey of twenty homes within the problem area. This survey, and the extensive water quality testing program which we are conducting in conjunction with the survey, is designed to obtain answers to the following questions: 1. Has the installation of the in -line pumps and chlorination station actually stabilized the water quality and chemical balance of the water within the water main system? 2. To what extent has the improvement of the water quality within the water main system resulted in improved quality within the homes in that area? and 3. Why do some homeowners within the problem area experience severe problems while other homeowners within that same area (sometimes the immediate neighbors) report no problems? Following completion of this survey and testing program we expect to offer answers to these questions and offer additional recommendations which hopefully will provide that acceptable level of service which we seek. We expect to submit this report to the City Council by early November, 1986. August 22, 1986 Page 3 In her note, Ms. Berg expressed concern regarding the long range effects of the chemicals used during the past several years. I wish to assure her and the City Council that all the chemicals used by the City are approved for use in municipal water supplies and that the concentrations used have been within the limits recommended for safe use by the Minnesota Department of Health. At the same time, we recognize her concern, and we will continue to minimize the use of chemicals. In summary, it is my opinion that we have not yet achieved an acceptable level of service to this area. However, we expect to submit recommendations for achieving that objective in the near future.

Splinter, City Manager FROM: Sy Knapp, Director of Public Works DATE: April 16, 1987 RE: Water Quality Improvements - Status Report Attached hereto are the following items: - a "Summary Report" dated February 13, 1987, of the study conducted by SERCO between June, 1986 and February, 1987 (copies of the lengthy technical report are also available at our office) - a March 4, 1987 letter from SERCO - an April 6, 1987 letter from SERCO As indicated in these reports, a great deal of study and analysis has been conducted during the past year. Also, two principal actions have been taken, i.e.. - increased chemical treatment of the water has been initiated to reduce the corrosiveness of the water. Note: As shown in the attached reports, we have experimented with several variations of chemical treatment. It now appears that the most positive results are obtained by the use of Zinc Orthophosphate. - installation of three new in -line pumps within the watermains in the area which has experienced the most severe problems. - Note: These pumps do a good job of circulating the water. However, we have received complaints from adjacent residents that the noise from the pumps is resonating in their plumbing systems, disturbing their sleep. We are working with the pump supplier to resolve this problem. Until it is resolved, we are shutting the pumps off overnight. While this reduces the noise problem, it is counter - productive to our efforts to circulate the water. T 1 roseui4wFZiucm =�'' April 16, 1987 Page 2 It is my opinion that these measures have had positive results. Testing of water at individual homes within the problem area has shown that iron levels in the water supply are substantially reduced and that chlorine residuals are being maintained at a proper level. However, I must also note that the estimated costs for these measures is $50,000 per year. Because it is very difficult to evaluate the long term effects of these measures based on short term experience, it is my recommendation that we continue on our present course of action (i.e. continuous operation of the in -line pumps, once the noise problem is resolved) for 4 to 6 months, then evaluate the results and decide whether or not to continue on this course. If a decision is made that replacement of some of the watermains is required, plans should be made to do that work early in 1988. One additional recommendation is made, i.e. to install a loop watermain on Paul Circle, so as to eliminate the dead end conditions which exist on that street. So long as this dead end exists, the in -line pumps have no effect on that line, and the effects of water treatment are substantially reduced. The estimated cost for installing this loop main on Paul Circle is $20,000. If the City Council wishes to do so, this main can be installed in 1987. I recommend that this matter be discussed with the City Council at their April 20, 1987 meeting. Following that discussion, City staff will communicate this information to the neighborhood residents.

As you know, we have made several attempts to find solutions to this problem. While it is our opinion that substantial progress has been made in reducing the scope and severity of the problem, we also recognize that continued problems exist. To make continued progress in resolving this problem with an economically feasible solution, we need to obtain additional information. To obtain that information we are asking a selected sample of property owners in your neighborhood to answer the enclosed questionaire. Some of the property owners selected to receive this questionaire have previously reported water quality problems, while others who are receiving this questionaire have indicated to us that they have little or no problem with the water quality. By asking each of you to respond to the questionaire we hope to be able to identify some of the factors which contribute to the water quality problem and develop some answers to the problem. We ask that you answer the enclosed questionaire, then retain it until you hear from us. One of our employees will contact you by telephone to set up an appointment when he can come to your house for the purpose of picking up the completed questionaire and assisting you in answering any questions which you have. At the time when the employee visits your house to pick up the questionaire he will also review your water system in some detail, and he will wish to obtain one or more samples of water at specific locations in your house. These samples will be tested and analyzed for the purpose of finding solutions to the problem. Our employee will contact you by telephone in approximately a week to ten days. We ask that you answer the questionaire now so that it is complete and available at the time when our employee calls you. �*c F A 19R Y1AMERMJ OI7 q �.

Phone: (612) 636 -7173 � _ October 14, 1986 Mr, Dick Ploumen Public Works Superintendent CITY OF BROOKLYN CENTER 6301 Shingle Creek Parkway Brooklyn Center, MN 55430 Dear Dick: I have enclosed draft copies of three tables presenting the laboratory data for the samples that your staff and I collected during July and August with reference to the Drinking Water System Study that SERCO Laboratories is per- forming for the City of Brooklyn Center. I have not completed the report but wish to share the information that I have available to -date for your review. It is clear that corrosion does exist in the water system and apparently mostly in the area where the major complaints are received. The level of Iron in the water supply is low, except for the water from Well No. 2 which I understand is used very infrequently. It can, therefore, be assumed that the presence of Iron at the users' homes are caused by corrosion and not by the supply itself. The level of Manganese, however, is relatively high and substantially above the recommended limit of .05 mg /L. The Sulfate concentration in the well water samples that I collected are relatively high and if Chlorine is not present, it can be anticipated that Hydrogen Sulfide odors could occur, and in fact have been reported by some of the users in the Questionnaires. The level of Iron in the distribution system samples are relatively low, except for the sample collected at Evergreen Park, and the sample collected from the hydrant located at Regent and Eleanor. This supports the corrosion problem that exists in the area of most of the complaints and it is probable that the higher Iron level at Evergreen Park is due to the water that has been standing in the service line to the Park Building which has apparently caused corrosion in that service line. It should also be noted that where Chlorine is present in the dis- tribution system and at the residences, it is usually present at approximately 1.5 mg /L Total Chlorine, and is mostly Free Chlorine, as noted by the sample collected at 5309 Bryant Avenue. It is probable that this high level of Chlorine Residual is contributing to the rate of corrosion in the distribution system. When Quality and Service Count Yj Mr. Dick Ploumen Page 2 Concentrations above approximately .5 mg /L are reported to cause an increased rate of corrosion. If it is possible to maintain the level at approximately .5 mg /L in the system, and insure that Chlorine Residual is present throughout the system, it would be the most desirable arrangement. This is apparently easier said than done, based upon the data collected during this survey, and the data collected previously. It may be desirable, if you're not using Chloral means, to consider that approach of Chlorination. It is noted that the concentra- tion of Zinc is approximately between .15 and .2 mg /L in the system samples. I assume that this concentration is maintained by the addition of Zinc Ortho Phos- phate. It may be desirable to adjust the dosage of this corrosion inhibitor additive upward, in order to help reduce corrosion in the affected area in the distribution system. A variation in dosage may be in order throughout the year with an increased dosage perhaps during the summer months when the water temperature may be somewhat higher in the system. It would appear that it is also desirable to increase the pH of the water in the distribution system to insure that the Saturation Index is positive, rather than negative, as has currently been calcu- lated and is shown on the tables. The Langlier Saturation Index has generally been calculated at a -.5 to -.6 in the water collected. This number should be slightly on the plus side. I have offered up this information only for preliminary general review by you, Dick, and do fully expect to complete a comprehensive report with supporting information and more specific conclusions and recommendations. Please accept the contents of this letter in that context. I expect to be away from the office until Monday, October 20, and will be in touch with you, and I do plan to complete the report of this study by the end of October.

Per your request I will review in detail and tabulate the information from the residential questionnaires along with comments and review of tabulated information so that it can be incorporated in the comprehensive report to you by January 23. You also have requested that I do an executive summary report of our study with a draft of this report to you by January 30, This executive summary should include only the pertinent information and be written in such a way to be easily read. It is my understanding that you will have comments back to me with regard to these two draft documents by February 9. I will then expect to have a final detailed report including the above noted tabulation and the executive summary report in final form to you by February 13 so that you will be in a position to present this material to the City Council on February 23. It is my understanding that Dave has begun to add the zinc ortho phosphate corrosion inhibitor at five times the concentration it was previously added beginning on Wednesday, January 7. It can be anticipated that this higher level of zinc addition will continue for a period of one to two months and that it will be regularly monitored to determine its effect upon the corrosion within the system. I would expect to have a progress report regarding this work to you by February 13 as well. In the interim I will evaluate and determine the detailed procedures for the adding of the pH adjustment chemicals which is part of the second phase of our continuing study.

GSA /cgk f B -4 SUMMARY REPORT STUDY OF THE WATER QUALITY IN THE WATER SYSTEM CITY OF BROOKLYN CENTER BROOKLYN CENTER, MINNESOTA JUNE, 1986 - FEBRUARY, 1987 Prepared by: tG Gerald S. Allen, P.E., Project Manager SERCO Laboratories 1931 West County Road C2 St. Paul, MN 55113 Dated: February 13, 1987 , TABLE OF CONTENTS Page SUMMARY STATEMENT . . . . . . , , , , . . 1 BACKGROUND DISCUSSION , , , , , , , , , , , , , , , 3 CONCLUSIONS AND RECOMMENDATIONS . . . . . 6 SUMMARY STATEMENT In summary, it can be concluded that the degraded water quality reported and observed in the study area is caused by the presence of iron and sediment resulting from the general corrosion of distribution system (both in the street and in the residence) as well as the presence of physical and hydraulic dead ends in the system. The quality of the water can be improved by minimizing the distribution system dead ends (both physical and hydraulic) and treatment of the water to reduce the tendency of the water to corrode the pipe surfaces. This corrosion can be controlled by increasing the dose rate of the corrosion inhibitor (Zinc Othro- Phosphate) and /or increasing the pH level of the water as well as minimizing the presence of Free Chlorine Residual in the water. -1- t BACKGROUND A detailed study of the quality of the water supplied to residences in an area on the western edge of the City of Brooklyn Center, roughly bounded by 63rd Avenue on the south, 65th Avenue on the north, Orchard Avenue on the east, and the City boundary or Unity Avenue on the West, was performed by SERCO Laboratories in 1983 and 1984. As a result of that study, the City initiated a program to improve the quality of the water provided to the residences in that area including regular flushing of the water mains during the summer months, continuous bleeding of the water to insure a fresh supply in the water mains, installation of inline pumps to move the water through the mains, addition of Chlorine into the water system, and addition of Zinc Ortho Phosphate, a corrosion inhibiting chemical to the water supply. These actions have improved the quality of the water provided to the residences in this area, however, complaints still have been registered by the users and a somewhat degraded water quality has been observed at some residences. Therefore, as a followup of the 1983 and 1984 study, the City of Brooklyn Center retained SERCO Laboratories to perform a study of the water quality in the water system in June, 1986, with particular emphasis on the quality of the water provided to the residences in the above noted problem area. -2- DISCUSSION Data and information was collected during the study by preparing a Water Quality Survey Questionnaire that was sent to the residences in the area where water quality complaints have occurred. A total of 20 completed questionnaires were returned and evaluated. Water samples were collected for analysis_at these 20 residences as well as from the eight supply wells and at six locations throughout the distribution system. Several service lines in the study area were excavated and inspected by the City to confirm that the services are tapped into the upper quadrant of the water main pipe so that any solid material that may have settled in the .eater main will not be drawn into the service pipe. All of the inspected services were tapped into the upper quadrant of the main. Unsatisfactory water quality, when present in a residence, was usually noted throughout the house, typically included red and rust -like solids and stains, with black objects and specs noted in some occasions. Odor and smell in the water was also noted in those residences where unsatisfactory water quality was experienced. The unacceptable water occurred on some occasions throughout the day, but was normally more prevalent in the early morning hours and in general on a seasonal basis more common in the summer than in the winter. People from four of the residences indicated that the quality of water had improved in the last year, however, people from a total of eight residences indicated that there had been no improvement in the quality of water during the past year. zero to 0.2 mg /L Total Chlorine Residual was measured in the residences on Unity Avenue and Paul Circle and in one residence on Eleanor Lane. A Total Chlorine Residual of approximately 1.5 mg /L is desirable in the water supplied to the user. Data and information collected through this questionnaire, along with the samples collected at the residences do not clearly identify why certain homes have a water quality problem while the neighboring homes do not seem to have the problem. This difference may be due to differences in the operation of the treatment units in the houses (water heater, water softener) that were not clearly identified in this questionnaire. -3- It can be concluded from the information collected at the 20 residences that the deteriorated water quality in several of the residences are due to the presence of high concentrations of iron (red and rust stains), of manganese (black solids and specs) and the lack of Chlorine in the water provided to the users. The people in 12 of the residences who returned questionnaires indicated that the quality of their water supply was unsatisfactory, while people from eight residences indicated that the quality of their water supply was satisfactory. The average water use per day per residence was approximately the same for both groups (220 gallons per day per residence). There is an average of 3.5 people living in the residences where the water quality was unsatisfactory compared to an average of 2.8 people in the residences where the water quality was indicated to be satisfactory. Based upon the information collected during this study, the water pumped from the wells and supplied to the residences of Brooklyn Center is safe for human consumption and is a good quality water for domestic use. The water is relatively hard and should be softened before being used for cleansing purposes. The concentration of iron in the water pumped from the wells is below the recommended maximum concentration of .3 mg /L except for well No. 2 which is seldom used. The low level of iron in the well water should not cause any water quality or staining problems as it leaves the wells. The manganese concentration is somewhat above the concentration recommended (.05 mg /L) as the water is pumped into the distribution system from the wells. These higher levels of manganese will tend to percipitate out of the water as black particles and may contribute to the presence of black -like solids. An evaluation of the chemistry of the water indicates that it has a tendency to be corrosive towards the metals in the distribution system and therefore releases iron into the water. When the water is softened it is more corrosive. Most of the City of Brooklyn Center distribution system consists of cement line cast iron water mains, and is, therefore, -4- protected from corrosion. However, unlined cast iron nine was observed at the three locations that inline pumps have been installed in the water system in the area where the water quality of the water supply has been indicated to be unsatisfactory (Unity Avenue, Regent Avenue, and Orchard Avenue). The City's water distribution system is designed to provide only Total Combined Residual Chlorine in the water system (Chlorine combined with Ammonia) and that no Free Residual Chlorine be present in the water. Free Chlorine has been measured in the Brooklyn Center distribution system at levels as high as 1.4 mg /L. This high level of Free Chlorine Residual can contribute to the tendency of the water to be corrosive towards the metals in the distribution system. Sulfate is present in the water supplied and if a Chlorine Residual is not present at the point of use, it may contribute to the production of hydrogen sulfide and cause a rotten egg smell. A trace of hydrogen sulfide odor was noted at five of the supply wells. The presence of hydrogen sulfide also tends to enhance the corrosivity of the water supply. -S- CONCLUSIONS AND RECOPM4ENDATIONS 1. It is recommended that well No. 2 not be used except on an emergency basis when all other well supplies are fully in use because of the high iron content of the water and the presence of DO. 2. It is recommended that well No. 6 be used as a standby supply because of the presence of DO, except that this well be used before well No. 2. 3. Both the Total and Free Chlorine Residual should be monitored throughout the distribution system and if needed, the Chlorine and Ammonia dosage adjusted to provide for a maximum combined available Chlorine Residual level of 1.5 mg /L throughout the system and that no Free Chlorine be present in the system. 4. The Zinc concentration in the distribution system is between 0.15 and 0.2 mg /L, as a result of the addition of the corrosion inhibitor (Zinc Ortho- Phosphate),which is below the suggested Zinc concentration of 0.5 -1.0 mg /L needed to help control corrosion. Therefore, it is recommended that the dosage of Zinc -Ortho Phosphate be increased to provide a Zinc concentration of 1 mg /L (5 times current feed rate) in the water supply, for a period of one to two months so that the benefit of this increased dosage can be determined. S. The City of Brooklyn Center water supply can be made less corrosive by increasing the pH of the water in the distribution system from approximately 7 to 7.5 -7.7. This higher pH will tend to cause a protective film of Calcium Carbonate to develope on the surfaces of the distribution system. Therefore, it is recommended that pH adjustment chemicals be added to the water supply for a period of one to two months to determine the effectiveness and economics of this procedure at Brooklyn Center. 6. The new recirculation pumps installed at Regent Avenue, Orchard Avenue, and Unity Avenue should be operated on a continuous basis. -6- The installation of the inline pumps has helped to minimize the hydraulic dead zones in the water mains where the water quality problems have occurred and has improved the level of Chlorine in the water. This improvement in the mains has also caused the Chlorine Residual to increase in many of the residences where a low Chlorine Residual was previously noted. The addition of Chlorine into the water in the main on Regent Avenue did help to increase the Chlorine Residual in the water at that location, but also caused localized corrosion of the water main. Therefore, Chlorine should only be added to the water at the wells, where Ammonium Sulfate is also added to the water. 7. The quality of the water at the residences on Paul Circle is degraded because these residences are serviced by a dead -end water main. It is recommended that water be bled on a continuous basis from the end of the Paul Circle 4 -inch distribution main or that the main be regularly flushed until this dead end can be eliminated by installation of additional water main. 8. All residential services should be thoroughly flushed after the quality of the water in the distribution system is properly brought under control and the iron concentration reduced to a satisfactory level (below .3 mg /L Total Iron). 9. The use of galvanized pipe, and the galvanized pipe in combination with copper at several of the residences, likely contributes to the corrosion problem at those residences. Galvanized pipe should not be used with copper pipe because the galvanized pipe is likely to corrode due to electrical action. The City should recommend that all galvanized pipe be replaced with a satisfactory copper or plastic pipe in the residential systems after the quality of the water in the distribution system is managed to an acceptable level. The City should further recommend that all of the residences regularly flush all of their hot water heaters to remove any sediment, and that the softeners and other treatment units 18 be thoroughly rinsed and cleaned in order to remove any sediment in them that may exist, but only after their services have been thoroughly flushed and plumbing changes made per the City's recommendations. -7- WATER QUALITY Q U E S T I O N A I R E CITY OF BROOKLYN CENTER 1986 Name Address Phone 1.

In accordance with our meeting of January 6th at your offices, we began to add the Zinc Ortho Phosphate at five times the previous dosage beginning January 7th. This dosage was again increased by about 30% on January 11th to insure that the Zinc concentration in the distribution system is maintained at approximately 1 mg /L. We have used the concentration of Iron in the water at the hydrant located at Regent Avenue and Eleanor Lane as a measure of the success of the increase dosage. It is assumed that if the Iron concentration at this location drops, the corrosion action in the system is reduced. The enclosed figure shows the measured concentration of Zinc and Iron at this location during our study in January, February and March. The concentration of Zinc in the system was 0.15 to 0.2 last; summer and the Iron at the mg/ L. hydrant was 0.55 m L. You will note that as we e continued the study that the concentration of Zinc began to level off at approximately oximatel 1 m Land the concentration Y g/ of Iron dropped to 0.15 to 0.2 mg /L. In my opinion, this is an indication that the Zinc inhibitor material is coating the piping and that the corrosion action has been reduced. The desired maximum concentration for Iron in a water system is 0.3 mg /L and we have maintained a concentration in the water below that level at the hydrant for over two weeks. Therefore, it can be assumed that at this higher Zinc Ortho Phosphate dosage that the corrosion apparently can be controlled. It is my opinion that if this material is continued to be used after our testing this spring, that a dosage resulting in a Zinc concentration of approximately 0.5 mg /L in the water system will control the corrosion. However, this will need to be confirmed if Zinc Ortho Phosphate is continued to be used.

You will recall, based upon the information I sent you in March, that we appear to be able to successfully control the level of Iron in the distribution system by using Zinc Ortho Phosphate at a level that will provide for a residual Zinc concentration of approximately 1 mg /L in the water in your system. It was decided that on the first of March we would begin to use Soda Ash (Sodium Carbonate) to adjust the pH upward to 7.5 -7.7. This work proceeded throughout March, however, we found that substantially greater amounts of Soda Ash are required than we originally anticipated and that the addition of this material on a test basis will require a significant increase in the chemical feed capabilities at the wells used during the tests. We then did a short test run late in March using Caustic Soda and established on a short -term basis a level of Caustic Soda that could be added using the existing chemical feed equipment. We determined on a preliminary basis that between two and three gallons per hour of 50% strength Caustic Soda needs to be added at the well when it is continuously pumping in order to raise the pH to our desired target level. However, in order to proceed with the use of Caustic Soda, it would be necessary to purchase the Caustic Soda in addition to the Soda Ash that has already been purchased for this test. SERCO had a small quantity of Caustic Soda that was used for the short -term preliminary testing. Based upon the preliminary information, it was concluded that the cost of pH adjustment may be nearly the same as the cost of using the Zinc Ortho Phosphate depending upon the ultimate feed concentration that we expect to be acceptable for the Zinc Ortho Phosphate. When Ouaiity and Service Count April 6, 1987 Page Two Therefore, Dave and I decided that we would proceed, beginning the first of April, to reestablish the level of Zinc Ortho Phosphate in the system at 1 mg /L and then begin to gradually reduce the concentration of Zinc to its optimum dosage which I would expect may be approximately .5 mg /L. Once we have established the optimum dosage of Zinc Ortho Phosphate we can then do an economic evaluation and decide if we should proceed with the testing using chemicals to adjust the pH of water in place of the use of the Zinc Ortho Phosphate. I would anticipate that we should be able to establish the optimum dosage of Zinc Ortho Phosphate in approximately one month to six weeks. I trust that this approach is acceptable to you and that the information contained in this letter is helpful to you in determing the status of our work in the water system. If, however, you have any questions or comments regarding the contents of this letter or any other aspect of this study, feel free to contact me at your convenience. Sincerely, SERCO Laboratories A , G d S. A en, P.E. cc: Dave Peterson GSA /cgk B -7 OBSERVATIONS AND COMMENTS by Serco Laboratories November, 1987 1. The water system corrosion can be controlled when the Zinc concentration in the water system is at 1 mg /L through the addition of Zinc Ortho- Phosphate (40 -50 lbs. /MG) based upon data collected in February, March and April of 1987. It would appear that the optimum Zinc concentration to be maintained in the water system is 0.5 -0.7 mg /L (20 -30 lbs. /MG)to control water system corrosion. 2. Based upon the results of this study and the work of the City staff including water main flushing, chemical monitoring and field observations; the corrosion control procedure using chemical coating of the unlined water mains is very fragile and subject to small changes in the water quality and chemical dosage. 3. When Well #2 is used, it appears to supply water to the study area because of its location relative to the location of the other supply wells. Corrosion control chemicals are not added to the water at Well #2 which is likely to result in a reduced level of this chemical in the study area when Well #2 was used (3 days in May, 16 days in June and 4 of the first 6 days in July). The Chlorine level in the water also appeared to be less at this time. I These lower chemical feed dosages appear to have a significant negative impact upon corrosion control of the mains in the study area. 4. Once the protective Zinc Ortho- Phosphate coating is removed, it takes time to replace the coating so that it can be effective again, based upon the data collected during this study and appears to explain the degraded water quality in the system at the study area in August and September. 5. The pumps located in the system on Regent Avenue and Unity Avenue appear to help maintain the quality of the water in the system when the pumps are operated continuously. It appears that the pump in the water system located on Orchard Avenue is not needed and should not be operated. 6. The City's supplier/ of the Zinc Ortho- Phosphate has suggested that a different compound, a Zinc Poly- Phosphate, may perform better to control the Brooklyn Center water quality in the distribution system because of the presence of Manganese in the supply water. Both compounds cost approximately the same to purchase. The Ortho- Phosphate (currently used chemical) will control system corrosion better and the Poly- Phosphate will control the chemicals contained in the water supply better. If the City decides to study the use of the Poly- Phosphate, this evaluation should be performed during low water demand and should be completed by the end of January, 1988, so that a balanced chemical dosage can be established before the high water demand time. • 7. Corrosion control in the water system b y y increasing the pH level of the water was studied and it appears that this procedure may be successfully used, but at a higher chemical dosage than originally estimated. The use of pH adjustment chemicals will require additional capital cost for chemical feed equipment and chemical storage. RECOMMENDATIONS B_8 by Serco Laboratories November, 1987 1. It is recommended that the City begin a program of replacing the unlined water main in the study area with a lined water main to reduce the potentially corrosive surface in the system. When the economics of this recommendation is studied, the following costs need to be considered: cost of corrosion control chemicals, cost of water lost to bleed water at hydrants and that used to perform the extra flushing, cost of ongoing consulting services, and the cost of City staff time in working on this matter. Replacement of the unlined water mains will provide a relatively permanent solution to this matter. However, the above -noted other costs will not be significantly reduced until all of the unlined pipe in the area is replaced. The City m wish t continue p y y o co ue to add Poly- Phosphate to the water to control the precipitation of the Manganese even after the unlined main is replaced. 2. It is recommended that the use of Zinc Poly- Phosphate be evaluated during November and December to determine if it may be as effective as Z 0 inc rtho Ph osphate as a corrosion control chemical. 3. It is recommended that pH adjustment chemicals not be used eventhough the annual chemical feed cost appears to be less than the Zinc chemicals because of the significant additional first cost. It is recommended that this capital be invested in lined replacement water main if it is to be spent. r 4. The use of Well #2 must be minimized. When Well #2 is pumped, all of the normally used chemicals added to the water, must be added at Well #2. The necessary chemical feed equipment should be installed at this well before it is used again.

REPETI COMPLAINT 19 87 CITY OF BROOKLYN CENTER council Meeting Date . � / 2/22/88 Agenda Item Number x REQUEST FOR COUNCIL CONSIDERATION ITEM DESCRIPTION: DISCUSSION OF LOCAL AID PROPOSALS -- STATUS UPDATE DEPT. HEAD'S APPROVAL: Signature - title MANAGER'S REVIEW /RECOMMENDATION: No comments to supplement this report Comments below /attached x SUMMARY EXPLANATION: (supplemental sheets attached x___) The purpose of this discussion item is to update the City Council on the status of local government aid proposals being presented to the State Legislature during this legislative session. Attached please find the following information: Copy of the State of the Cities booklet for 1988; copy of a February 10, 1988 Bulletin from the Association of Metropolitan Municipalities giving this group's position on the property tax reform proposals and local government aid; and a copy of an article describing the various proposals that will be considered by the State Legislature from the Citizens League Newsletter. It is too early to tell which of these proposals, or more likely which combination of these proposals, will meet with favorable approval from the Legislature. It is your staff's opinion that the principles embodied in the Metropolitan Association of Municipalities Bulletin of February 10, 1988, represent the general outline of a policy we could recommend for City Council for consideration. The local government aid issue and property tax reform become intertwined because these various property tax reform proposals affect the ability of all cities in Minnesota in some fashion to raise revenue through property taxes. While we have been unable to analyze in minute detail all of these proposals, the vast majority of them appear to not treat the City of Brooklyn Center kindly. Under most of these proposals the City of Brooklyn Center would not see increases in state aid and the reform proposals appear to shift the tax burden toward metro suburban communities such as Brooklyn Center. By the time you discuss these various proposals Monday evening, you will have the opportunity to meet with and hear discussion regarding these legislative proposals at a Saturday morning, February 20, breakfast meeting with legislators in Constitution Hall. From a municipal standpoint, municipal lobbying efforts on this subject seem to be in disarray. Factions have coalesced to attempt to structure tax reform and LGA formulas to direct funds toward differing groups of cities. Central core cities have coalesced with certain outstate cities; certain suburban communities have coalesced, and I believe the net result is that we are presenting a mixed, confused picture to our state legislators. In the long run if this process continues, the overall impact on municipalities will be very negative. With many voices speaking many languages to the State Legislature regarding municipal needs and if we continue to compete with each other in various coalitions, the net result will be that our message and our real needs will be presented in a confused picture that will not be seen nor be appreciated by the Legislature. RECOMMENDATION It would be my recommendation that the Council direct the staff to keep in touch with all the various coalitions, the Metropolitan Association of Municipalities and the State League of Cities, and report back periodically to the City Council on the progress of the various legislative activities. We also recommend that the City of Brooklyn Center establish a policy by motion which directs the staff and the members of the City Council to seek the elimination of the factional ization of municipal lobbying efforts between various coalitions and move to a more unified direction among municipalities as a long term policy. In the interim the City should lobby to protect itself and similar suburban communities from being adversely affected by changes in state taxing and aid formulas.

This year's report provides evidence that Minn - esota's cities are continuing to face economic stress as they struggle to maintain adequate service levels while coping with extremely large cuts in federal aid and the prospect of diminishing assistance from the state. The Federal Government is no longer a reliable financial partner in providing city services. Its massive fiscal difficulties and a change in philosophy about inter- governmental relations have caused a withdrawal of support for cities. As of 1987, the Federal Government terminated its general revenue sharing program which had provided Minnesota cities with over $40 million annually. Minnesota's state government has struggled to fill the revenue gap caused by federal funding withdrawal, but it too has had budget problems and has shifted its budget priorities. Financial difficulties are partly responsible for limiting Minnesota's ability to share state revenue with its cities. But changing budget priorities have also led the state to dedicate a declining share of its budget to city aid. Against this backdrop of dwindling resources, cities have had to deal with man - dates and similar federal /state restrictions that are increasing the costs of providing services and operating government at the local level. Mandates such as comparable worth, fair labor standards, and wastewater treatment requirements have adversely affected cities just as the 1986 federal tax act imposed new restrictions on cities' revenue - raising abilities. The main findings of this report, summarized by Chart 1 on page 2, are: * Federal aid to Minnesota cities has declined 48 percent in real dollar terms over the 1978 -86 period. * Minnesota's state government has been unable to substitute through the local government aid and other property tax relief programs for the federal assistance which cities lost over the past decade. State aid in 1986 stood at a level only slightly higher --3 percent higher in real dollars -- than it was in 1978. * City spending cannot be blamed for large increases in property and other local taxes. As of 1986 (the latest available State Auditor's data), • per capita city spending in real dollars was one percent below per capita city spending in 1978. * As further evidence of the budget restraints on cities, the total number of city employees dropped a dramatic 24 percent between 1980 and 1985, more than three times the rate of decline in employment of any other state or local governmental unit in Minnesota. -3- * Between 1978 and 1986, city property and other local revenue rose 22 percent in inflation- adjusted dollars. Less federal and state assistance, not rising city spending, has required Minnesota cities to rely more heavily on property and other local taxes. * Cities' heavy dependence on local taxes gives them every incentive to be responsible in their spending patterns. While Minnesota cities must raise 63 percent of their revenue locally, counties raise only 46 percent of their revenues locally and school districts raise 44 percent locally. * As cities have been forced to use their tax bases more heavily, those bases have either been declining or growing at a dramatically reduced rate. Between Payable 1986 and Payable 1987, taxable values dropped in one out of every four Minnesota cities. Over the 1983 -1987 period, cities gained taxable wealth an average 3.7 percent per year, less than one -third the 12.8 percent annual rate of growth for the 1979 -1983 period.

A severe recession in 1981 -82, an es- calating federal deficit, and a number of budget crises at the state level have all converged on Minnesota's state and local governments and have decreased the financial resources available for the delivery of services. Financial data clearly indicate that economic assistance provided to Minnesota cities by federal and state governments has dropped significantly over the past decade. As evident in Chart 2, the most precipitous decline occurred between 1978 and 1982 when both federal and state governments were withdrawing financial sup- port. Since 1982, the rate of decline has slowed somewhat. However, with the 1987 elimination of $40 million in federal general revenue sharing and the limits placed on the state's local government aid funding, total aid to Minnesota's cities is projected to resume its steep decline. In real (inflation- adjusted) dollars, combined federal and state aid to Minnesota cities dropped 16 percent between 1978 and 1986 according to State Auditor in- formation. With the elimination of general revenue sharing in 1987, the total decline between 1978 and 1987 is projected to be 23 percent. This projected decline is shown by the broken line in Chart 2. (See Table 2 in Appendix for relevant statistics.)

Between 1978 and 1986, i t 86, aid o Minnesota cities dropped 48 percent. In 1978, federal aid represented over 15 percent of total revenues for Minnesota cities, but by 1986 that share had been cut almost in half, dropping to 8 percent. Whereas federal aid in 1978 contributed $3 for every $4 raised in property taxes by Minnesota cities, by 1986 federal aid provided only $1.15 for every $4 raised in city property taxes. State Aid Trends. As federal assistance to cities has plummeted, the state has tried to fill the resulting revenue gap through the local government aid program and other ro rt tax e a relief programs. Yet t p p y p he state's fiscal problems, revenue volatility . g p Y and changing budget pr have prevented this. Local government aid (LGA) represents the largest portion of state aid to cities, providing over half of such funding. The LGA program is funded through an annual appropriation and therefore fluctuates from year to year depending upon the state's fiscal situation and other competing budget priorities. For example, large cuts in. LGA occurred in 1982 -83 as a result of the state's budget crisis. For 1988, LGA has been frozen at its 1987 level. After adjusing for inflation, funding for LGA in 1988 stood at a level 7 percent below what it was in 1979. (See Chart 3 below and Table 3 in Appendix.)

However, LGA funding and total state aid to cities have declined as a percent of state revenue. Thus, the state has become less and less willing to share its revenues with cities. The state's four largest revenue sources -- the individual income tax, sales tax, corporate and bank income tax and motor vehicle excise tax represent 70 percent of all state revenue. As illustrated in Chart 4 below, in 1980, LGA funds represented 8 percent of the state's four largest revenue sources. By 1988, it has decreased to just above 6 percent. A two percentage point decline may not seem significant, however, 2 percent of these four revenue sources in 1988 is equal to over $90 million. Similarly, in 1980, total state aid to cities represented nearly 15 percent of the state's revenue from the four largest taxes. By 1986, that portion had declined to 12 percent. By 1988, that share can be projected to decline to 11 percent. (See Table 4 in Ap- pendix for assumptions underlying projections.)

For many cities, in- creased reliance on their own local taxes has made them hard pressed to continue to provide some program services.

SOURCE: MN STATE AUDITOR. -8- As displayed in Chart 5, this trend toward increased dependence on cities' own- source revenues began in 1980, but has intensified in recent years as federal and state aid has decreased. As of 1986, cities relied on their local taxes for over 63 percent of their total revenue, up from 56 percent in 1978. Intergovernmental revenue (predominantly federal and state aid) represented of 44 percent of city revenue in 1978, dropping to under 37 percent in 1986. Local property taxes and special assessments account for the largest portion of cities' locally- derived revenue. In 1978, these local property taxes represented only 32 percent of cities' revenues. By 1986, they represented nearly 38 percent of cities' total revenues. Less reliance on federal /state aid and more reliance on local property taxes can have negative effects on the state's tax structure. Less Equalization. Federal and state assistance have played an important role in Minnesota local government finance. Minnesota cities are quite uneven in their capacities to raise local revenues. Federal and state aid has acted to equalize these disparate tax capacities, making basic and essential services more affordable for many communitites. If aid continues to decline, the gap between the haves and have - nots among our communities will widen, making basic services less and less affor- dable for some communities. Increased Regressivity of State's Tax System. In recent years, the shift toward increased reliance on the property tax coupled with reductions in the state's income tax have made our state -local revenue system less progressive - -that is, less related to an individual's ability to pay taxes -- than it was previously. The decade of the 1970s was marked by bold policy initiatives that increased Minnesota's reliance on the in- come tax and sales tax so that local property taxes could be reduced. With the declines in federal and state aids in the 1980s, this set of policies, the "Minnesota Miracle," is gradually being reversed. -9- REDUCED PROPERTY TAX BASE GROWTH FOR MINNESOTA CITIES During the 1980s, as Minnesota cities have become forced to rely more heavily on their local property tax base, that base has either been declining for many com- munities or growing at a dramatically reduced rate. Between Payable 1986 and Payable 1987, 208 cities - -or about one out of every four of Minnesota's 855 cities experienced declines in their assessed property values. Cities experiencing the largest declines were predominantly small cities with taxable wealth of less than $3 million. For those cities which have been gaining taxable wealth, growth rates have dropped precipitously in recent years. As described in Chart 6 below, between 1979 and 1983, total taxable values for cities grew at an average annual rate of 12.8 per- cent. But in the more recent 1983 -1987 period, cities' taxable values grew at an average 3.7 percent annual rate, less than one -third the previous pace. Dampened growth in tax bases coupled with declining federal and state aid have placed financial pressure on many cities. Neither their taxable wealth nor state or federal aid have kept pace with the rising costs of the services they deliver.

The record on city spending ` clearly does not support these contentions. As of 1986 (the latest available State Auditor's data ), per capita city spending in P P Y p 9 real dollars was no higher than it was ten years ago, in 1978. (See Chart 7 below.) According to State Auditor's data, per capita city spending in 1978 stood at $359.34. After discounting for inflation, per capita city spending in 1986 stood at $355.58, one percent below the 1978 level. (See Table 7 in Appendix for data.)

OF COMMERCE FOR STATE & LOCAL IMPLICIT PRICE DEFLATOR. - 11 - I Chart 7 also illustrates that er capita city spending declined p p y p g dec ed sharply in the early 1980s, a result of cuts in state aid prompted by the state's budget problems. During that time, cities curtailed spending by reducing the number of employees and by delaying needed capital improvements and other projects. Since 1983, city spending has begun to rise again as cities have found it necessary to move forward with previously- delayed projects. CITIES COSTS FOR INFRASTRUCTURE AND PUBLIC WORKS RISING In January 1988, State Auditor Arne Carlson released the annual report on city revenues, expenditures and debt for 1986. The report indicated that cities spent 10.8 percent more in 1986 than they did in the previous year. In releasing the report, State Auditor Carlson praised cities for their efficient delivery of services and made clear that city governments were not the culprits for such a large spending increase. The Star Tribune news article (1/30/88) reported Mr. Carlson's opinions: "The blame for higher spending lies not with the cities .... The fault is with the federal government for spending cuts in areas such as water and sewer improvements .... And it lies with the state government for not sharing the bur- den, and indeed unloading its burdens onto the cities." The Auditor's report for fiscal year 1986 indicated that cities in Minnesota spent $396.1 million for streets and highways in 1986, up 8.1% over 1985. Almost sixty percent of these expenditures were for new equipment and construction. Costs of major infrastructure projects increased dramatically for cities in 1986. Capital expenditures for enterprise operations such as municipal sewer and water systems, electrical power plants, ambulance services, and recreation operations to- taled over $100 million dollars, a 47.2% increase over 1985. Both of these increases result more from the elimination or decrease in federal assistance through general revenue sharing and wastewater treatment facility con- struction grants than from increasing the size or number of public works projects. (See section on "Reduction in Federal Grants and Aid to Cities" for more detailed discussion.) The state government has also been inconsistent in its efforts to share in the burdens handed down to cities by the federal government. While the federal retrenchment is likely to continue, the state has given some indication that it may commit funds to assist local communities in providing necessary transportation, sewage treatment, water and other public services. In the area of wastewater treatment, 1986 state and federal grants provided 50 and 55 percent, respectively, of the funds needed for municipal projects. The state in 1987 provided substantial financial assistance through the issuance of state bonds in an attempt to ensure a state and federal share of 80% of facility construction costs. It is uncertain at this time whether the commitment to this financing level will hold when reviewed by the 1989 legislature and administration. While the state has increased its funding commitment for improved sewage treat- ment facil ',ties, its commitment to transportation financing is uncertain. In 1987, the -12- state failed to transfer proceeds of the motor vehicle excise tax from the general fund to the highway user fund or to provide an alternative funding source for state, county, and local roads and transit. This failure is expected to result in less road maintenance and construction and increased local costs. It is hoped that the administration and legislature will act during the 1988 legislative session to provide additional transporta- tion funding. The recent experience with wastewater treatment and transportation funding is compelling evidence of the need for the state to evaluate its long term role in provid- ing financial assistance in the public works and infrastructure areas and to make a commitment that eliminates the rapid and extreme swings in assistance programs. Pay As You Go State Government Costly To Cities Like other levels of government, including cities, the state has over the past several years increased many of its application, license, and user fees in an attempt to increase its revenue sources and lower its reliance on tax revenues. Many of these fees have risen significantly and increased the fiscal pressure on cities. One example is air and water quality permit fees. Cities paid $750,000 for water quality permits in 1987, usually for the operation of central sewage treatment facilities. In 1988, that amount is estimated to soar to $1,068,622. While the increased revenues from these fees will relieve pressure on the state general fund, the shift to cities and other permittees which is required to generate the target fee revenues will result in an average 74% fee increase per city. -13- CITIES HAVE HEAVIEST RELIANCE ON LOCAL TAXES Over the past decade, cities have had every incentive to be frugal in their spending patterns. Federal and state assistance to them has declined and they have been forced to rely more heavily on their local tax bases. The argument that city officials are not accountable for their spending is absurd in light of the evidence that city spending in real dollars has not increased, but local taxes have. As indicated in Chart 8, cities' heavy reliance on local taxes is in sharp contrast to how other local units of government in Minnesota finance their expenditures. Ac- cording to State Auditor's information, while cities raise 63 percent of their revenues locally, counties raise only 46 percent of their revenues locally and school districts raise only 44 percent locally.

Personnel costs comprise approximately 60 percent of most cities' budgets. The number of city employees (both full and part -time) in Minnesota declined by nearly one - quarter (24 percent) over the 1980- 1985 period. In contrast, the number of employees for all cities in the U.S. increased nearly 3 percent over the same period. The rate of decrease in city employment was more than three times the decline of any state or local governmental unit in Minne- sota.

The League's 1986 -87 City Budget Survey revealed that a large number of Minnesota's larger cities have ex- perienced sizable increases in their payroll costs as a result of implementation of the state's comparable worth law. On average cities responding to the Survey estimated their payroll costs would rise by 4.5 percent which is equivalent to approximately $30 to $35 million in increased costs statewide per year for Minnesota cities. Payroll costs generally comprise g y p se over 60 percent of the average city's budget. -16- City Services Provided More Efficiently. Minnesota's cities tend to provide ser- vices more efficiently than the average for all American cities. Based on the latest available statistics (1985), per capita, full -time employment in Minnesota for city ser- vices such as police and fire protection, sewage and sanitation services, water supply and housing and urban renewal are well below the national average. As indicated in Table I, per capita employment for all service functions of Minne- sota's state and local government units (including schools, counties, cities and townships) is about 7 percent below the national average. However, for police protec- tion, Minnesota public employment is 29 percent below the national average; for fire protection, our state is 54 percent below the national average; for housing and urban renewal, we are 56 percent below average; for sewage and sanitation, 29 percent below average. ........................................................................................................... ...............................

In 1986 -87, Minnesota cities and counties received $46.7 million Community Development Block Grants (CDBG). For Federal Fiscal Year 1988 (October 1, 1987 - September 30, 1988), cities and counties can count on receiving an average of 4 percent less than last year. Deficit reduction negotiations between Congress and the Administration actually resulted in greater losses to cities than those proposed earlier by either House or Senate. Cutbacks to entitlement cities those over 50 000 population r i ( o n a SMSA) could reach 5.2 P er- cent this r yea since more cities in Minnesota are now eligible under that program. The eight entitlement cities in Minnesota will receive a total of $22.9 million in CDBG funds this year. Non - entitlement cities will benefit from $17.6 million in Small Cities CDBG competitive grant funds for '88; four urban counties in the state will receive $5.7 million. In addition, the reduction in tax incentives for low and moderate - income housing construction (as a result of municipal bond restrictions imposed by the 1986 Federal Tax Reform Act) was compounded by further cutbacks in federal housing assistance. Nationally, these funds declined by more than 3 percent compared to the previous year. Clean Water /Wastewater Treatment. For cities waiting for federal matching grants to comply with federal clean water standards there was more discouraging news accompanying the deficit reduction agreement. Grants for wastewater treat- ment construction were also cut by 4 percent, leaving cities with $28.6 million in federal grant funds, compared with almost $30 million in 1986 -87. Transportation. Public transportation funding as well as federal revenues to as- sist highway construction and airport development have been disproportionately reduced for 1988. Nationally, transit funding suffered even more severe cutbacks than other areas of transportation funding. Cities in both urban and rural areas ex- perienced declines in federal transit assistance of an estimated $2.4 million since 1986 -87. Anti -drug Programs. In early November, 1986, President Reagan signed into law legislation authorizing $1.7 billion to eliminate drug trafficking, improve drug educa- tion programs, provide rehabilitation and treatment programs and reduce drug - related crime. Minnesota was scheduled to receive $7.4 million in Federal Fiscal Year 1987. Minnesota's share of the special local government and community group anti- drug campaign funding was set at $2.8 million. Faced with the deficit and competing demands for revenues, Congress has slashed funding by nearly 7 percent for fiscal 1988. Federal Mandates. In the meantime, many of the mnadates approved by the 1986 Congress have become effective during 1987. One, in particular, has affected cities, requiring officials to design more comprehensive emergency response plans for control of hazardous substances. Cities are discovering that they must comply with confusing and burdensome (even unworkable) requirements for extensive reporting and notification procedures. Severe civil and even criminal penalties apply -18- I for violations of either notification or reporting requirements for the newly mandated federal program. New gasoline (and perhaps diesel) fuel excise tax obligations for cities also emerged at the close of the 1987 Congress. No longer will cities be eligible for a tax exemption; instead cities must pay federal excise taxes at the time of purchase and then apply for a rebate from the federal government on a quarterly basis, thereby permitting the federal government the use and interest earnings (arbitrage) on the taxes paid by local (and state) government. For smaller cities which purchase less gasoline, the federal government appears intent on granting only an annual rebate of the amount owed. Tax - Exempt Financing. In the area of tax - exempt financing, cities continued to experience severe declines in the level of private activity bonding. Nationally, the reduction in municipal bond issues fell below $93.9 billion in 1987. The 1987 per capita state volume limit of $75 has now fallen to $50 per capita for 1988. Although Congress refrained from imposing new restrictions on cities' authority to use tax - exempt financing, it is clear that many federal lawmakers remain convinced that such measures are necessary to provide needed increased revenues to reduce the na- tional deficit. Cities' plans to finance purchase of privately -owned electric or gas utilities with municipal bonds also face new restrictions as a result of legislation approved at the close of the 1987 Congress. Acquisition of such facilities will only be allowed if the plant is 10 or more years old and does not increase the geographic service area of the city -owned facility by 10 percent or more. -19- • APPENDIX • • APPENDIX TABLES TABLE 1.

Based on many hours of study and debate, the Committee and Board determined to establish a set of priniciples rather than support or oppose any one entire legislative proposal, especially since each proposal has been changing almost daily and will most certainly be modified in the legislative process. Enclosed for your information and comment if you wish, is the Policy of Property Tax Reform Principles adopted by the AMM Board on a 14 to 2 vote at its February 4, 1988 meeting. Two major concerns arose during the discussion of the reform proposals. One was over an apparent shifting of current and future credit /aid from metro to outstate and the other was shifting more tax burden onto metro homesteads. The principles speak directly and indirectly to these major points. Some AMM Board members and cities do have a concern about point #12 which suggests adding $100 million. However, generally speaking if property tax reform is implemented with the intent to decrease the property tax burden on C/I and certain other property without increasing the burden on homes, then it is conceded by the majority that some additional money is needed. PLEASE CONVEY YOUR SUPPORT OF THESE VERY IMPORTANT PRINCIPLES TO YOUR LEGISLATORS! 183 university avenue east, st. paul, minnesota 55101 (612) 227 -5600 THE BOARD OF DIRECTORS OF THE ASSOCIATION OF METROPOLITAN MUNICIPALITIES SUPPORTS THE FOLLOWING PRINCIPLES AS APPLIED TO PROPERTY TAX REFORM PROPOSALS: CLASSIFICATION: 1. A property tax classification system of 10 classifications or less. 2. Reform measures should not artifically reduce property value in certain communities, increase property value disparity between high and low value communities, or reduce the ability to pay for locally determined needed facilities. 3. Changes to the classification system should include changes that keep Fiscal Disparities and Tax Increment Financing neutral. CREDIT /AID: 4. Maintain Homestead Credit and Local Government Aid as two separate programs. 5. A homestead credit system that provides relief to homeowners is preferred over an artificial system. 6. The link between local expenditures and both credit and aid programs should be severed for future increases to eliminate the perception of rewarding discretionary 7. State aid or Local Government Aid which is tied to increases or decreases in the state's general revenue (city, county, school, taxpayer). BURDEN: 8. Commercial /Industrial property tax relief is supported but not at the expense of metro area homesteads. 9. A system that provides equalization to the city, eount;y, school district and the individual taxpayer to some degree. 10. A multiyear computer run to analyze the long term impacts of a property tax proposal, and a review of the proposal regarding its impact on the distribution of tax revenue to the metropolitan and non - metropolitan areas of the state to insure that the imbalance or shift to non metro is not exacerbated. OTHER REFORM: 11. Review of the property tax burden upon high - valued homesteaded residential property. 12. At least $100 million additional annual revenue for property tax reform is supported. 13. A full disclosure property tax statement (discloses local taxing district levies, state paid relief and homestead relief). 14.

CITY OF BROOKLYN CENTER council Meeting Date 2/22188 Agenda Item Number �� C REQUEST FOR COUNCIL CONSIDERATION ITEM DESCRIPTION: DISCUSSION OF ANNUAL YEAR 2000 PLANNING PROCESS DEPT. HEAD'S APPROVAL: Signature - title MANAGER'S REVIEW /RECOMMENDATION: No comments to supplement this report Comments below /attached X SUMMARY EXPLANATION: (supplemental sheets attached X __) Attached please find a copy of a memorandum dated December 17, 1987, relating to the Brooklyn Center goal setting process. As a result of the city council's consideration of that memorandum, I've contacted Lyle Sumek, and we reviewed some of the discussion and council's thoughts regarding the • goal setting process. From that discussion with Lyle Sumek, I would like to offer the, following concept of a goal setting and planning process for your consideration. The process would be spread over two evening meetings commencing at 6:00 in the evening through 9:30 with an early dinner at the social hall The first session would be a session designed to discuss and develop a listing of issues and goals, and the second session would be a goal setting prioritizing meeting. We would recommend that these two sessions be held two to three weeks apart, and the first one would be in the first week of April and the second one during the week of April 25. Prior to the initial session, we would suggest that a questionnaire be sent out to commission members, committee members, staff members, and the city council with some suggested issues and goals and space for individuals to make their own suggestions. This pre- session questionnaire would then be returned, and Lyle Sumek and I would collate the lists and have it prepared for use at the initial issue and goal establishing session. After the initial session when the final listing of goals and issues is established and before the second prioritizing meeting is held, a second questionnaire would be sent out to all participants of the initial session and there would be a polling system asking them to establish their own priorities and return that to Lyle and myself. At the prioritizing session the week of April 25, the council, with the results of the issue questionnaire and the prioritizing or polling questionnaire, would then establish priorities. RECOMMENDATION It is requested the city council pass a motion approving the suggested goal setting prioritizing process (or a modified version thereof) and direct the staff to implement the process. A^& 4-41�4D M & C NO. 87 -23 December 17, 1987 FROM THE OFFICE OF THE CITY MANAGER SUBJECT: Brooklyn Center Goal Setting Process To the Honorable Mayor and City Council: In May of 1987 the City of Brooklyn Center conducted its first annual planning or goal setting session as recommended in the YEAR 2000 REPORT. The objectives of that session were: 1. to build the capacity of the "City Team" (City Council, advisory commissions, City staff and citizens) to provide leadership for Brooklyn Center's future. 2. to establish a common frame of reference for understanding a City - -how it is governed, how it is managed, and how services are provided. 3. to translate the vision of Brooklyn Center's future into a workable program by: S a. targeting specific policy issues that need to be addressed over the next two to three years. b. defining specific projects which are "doable chunks" during the next two to three years. 4. to establish a program for the ongoing targeting (goal setting) process in Brooklyn Center After the May, 1987 session the City staff received a number of comments from participants. Everyone was enthusiastic about the Process, but most participants thought its all day session on a Saturday was "too long" and the Saturday (weekend) timing cut down on the number of participants. I reviewed these comments With Lyle Sumek, our facilitator, and we concluded the session could be split into two weekday evening ening sessions: the first involving identifying goals and issues and the second for establishing priorities. During the May, 1987 session the City Council, City staff and citizen advisory commission members were involved in both identifying goals and issues and setting priorities. Mr. Sumek and I believe that all three groups should be involved in the "identifying goals and issues ", but the Council may want to consider establishing the priorities by themselves with discussion input from citizens and staff members. M & C No. 87 -23 -2- December 17, 1987 I also recommended that we develop a goal or project ( "doable chunk ") progress board or chart which is periodically updated and published to remind us of our goals and monitor our progress. At first this chart may be in "draft form" and develop changes over time to fit Brooklyn Center's needs. It will also give us notice when we complete our projects and allow us an opportunity to celebrate. Attached are listings of the three levels of priorities established at the May, 1987 session with staff comments on current status. Please review these "status listings" and let me know if any changes are warranted. At your meeting on December 28, 1987, I would like direction from the City Council regarding the following: 1. suggested modifications to the goal setting process -- should Council set priorities 2. should the annual process be continued 3. is the early spring timing and two weekday evening sessions proposed change acceptable 4. development of the project progress chart or board 5. any additional comments or directions from the Council Should you have any questions or comments prior to the meeting, please do not hesitate to contact me.
