RESOLUTION EXPRESSING APPRECIATION FOR THE GIFT OF THE ROTARY CLUB OF BROOKLYN CENTER TO PURCHASE AUTOMATED EXTERNAL DEFIBRILLATORS FOR THE CITY OF BROOKLYN CENTER Frank Slawson with the Rotary Club of Brooklyn Center addressed the Council on behalf of the Rotary Club to accept the resolution expressing appreciation for the gift of $8,000 to be used for purchasing three automated external defibrillators for the City of Brooklyn Center. Mayor Kragness read the resolution. RESOLUTION NO. 2003-79 Councilmember Peppe introduced the following resolution and moved its adoption: RESOLUTION EXPRESSING APPRECIATION FOR THE GIFT OF THE ROTARY CLUB OF BROOKLYN CENTER TO PURCHASE AUTOMATED EXTERNAL DEFIBRILLATORS FOR THE CITY OF BROOKLYN CENTER 05/12/03 -9- Application Filed on 4-17-03 City Council Action Should Be Taken By 6-16-03 (60 Days) Planning Commission Information Sheet Application No. 2003-004 Applicant: ATS & R (On Behalf of Osseo School District No. 279) Location: 3501 65th Avenue North (Garden City School) Request: Special Use Permit/Site and Building Plan Approval The architectural firm ATS & R, on behalf of Osseo School District No. 279, is seeking special use permit and site and building plan approval to construct a 10,740 sq. ft. building addition to the north and south sides of Garden City Elementary School and to create and reconfigure play areas at the school and the adjoining Garden City Park. The properties under consideration are the Garden City Elementary School (3501 65th Avenue North) and the adjacent Garden City Park (3607 65th Avenue North), which are both zoned R-1 (One Family Residence). The properties are bounded on the north by 65th Avenue with C-1 (Service/Office) and R-1 zoned property on the opposite side of the street; on the east by R-5 (Multiple Family Residence) zoned property containing the Garden City Court Apartments; on the south by C-2 (Commerce) zoned property containing the Rainbow and Walgreen's developments; and on the west by Brooklyn Boulevard with C-1 zoned property on the opposite side of the street. Public and private elementary schools and parks are both special uses in the R-1 zoning district. The proposal is to make two additions to the school, one at the northeasterly portion of the building for a new entry area and an expansion to the administrative offices in that area and the other at the southwesterly portion of the building for new classrooms, a mechanical room, connecting corridors and exits. The total of the building expansion is 10,740 sq. ft. Also planned is a reconfiguration of the school's north parking lot and bus drop off area as well as revised faculty and staff parking lot. Park and playground improvements comprehend a new school and park tot lot and play area including a soccer field and softball diamonds. The park shelter building will be relocated and there will be a revised hockey/ice skating area. A new 20 stall park parking lot will be added to Garden City Park. The park/school play areas and parking facilities will be jointly used by the City and the School District. An existing chain link fence and adjacent bituminous pathway generally separating the existing park facilities and school playground will be removed and relocated adjacent to 65th Avenue North to incorporate the play facilities into a more common area. A new bituminous path and entrance will be established on 65th Avenue North, east of Brooklyn Boulevard across from where Ewing Avenue intersects with 65th Avenue. The City's Park and Recreation Advisory Commission reviewed the proposed park modifications and upgrades at their April 15, 2003 meeting and recommended approval of the new plan. Anew cooperative agreement regarding the joint play facilities will be drafted and executed by the City and the School District. It should be noted that the School District is funding the park modifications and improvements as well as the additions to the school. 5-1-03 Page 1 Access to the school will be from two curb cuts on 65th Avenue North, which are slightly modified from the existing accesses. Instead of separating the bus loop/drop off area from the visitor parking and parent drop off area by chain barriers delineating a walkway between the sidewalk and the school entrance, a new separation, landscaped area and green strips will be established. New concrete walkways connecting the separated bus and parking areas to the school will be established as will a new entrance area at the northeast corner of the building. A new staff/faculty parking lot along the east and south sides of the building will be constructed allowing some additional landscaping to be accomplished adjacent to the east wall of the school. A new park parking lot accommodating 20 parking spaces is proposed for north of the bus loop and east of the relocated shelter building. It will have a separate access from 65th Avenue and will tie into the bus loop area but will have a double gate to prohibit mixing traffic from the two facilities when needed. The revised easterly access to the visitor parking, parent drop off area is approximately, 36 feet in width. When curb cuts exceed 30 ft. in width, we typically require a concrete delineator to separate the traffic coming into the site from that going out. Such a concrete delineator is recommended for this drive way. The plan indicates total parking of 103 spaces, 20 in the new park parking facility; 12 in the visitor lot; and 71 spaces in the staff lot to the east and south of the building. The plan notes that there are approximately 65 full and part time staff at the school. It is not anticipated that the building addition will cause any increase in staff numbers on site. There is no established parking formula in the zoning ordinance for schools and we have typically looked at providing parking based on the number of full time and part time employees as being a basis for determining adequate on site parking for schools. The number of parking spaces comprehended in this plan appears to provide enough parking for staff and visitors on a regular day-to-day basis. Special events at the school may occasionally require some on street parking, which is expected and understood. Six handicap parking spaces are shown on the plan for the staff, visitor and park parking lots. The plan calls for B-612 curb and gutter around all driving and parking areas. When Garden City School was last expanded in 1993, concerns were raised that curb and gutter should be installed consistent with city requirements. The Osseo School District indicated at that time that they had plans to upgrade parking facilities at all of their older schools within the next ten years. Curb and gutter improvements were deferred by the City for Garden City School at that time. The plans now submitted meet the commitment made by the School District at that time. 5-1-03 Page 2 The applicant has provided preliminary grading, drainage and utility plans which are being reviewed by the Director of Public Works/City Engineer and written comments are anticipated and will be attached with this report. Storm sewer will be provided to the newly upgraded parking facilities and a retention pond south of the building will be enlarged somewhat to accommodate additional drainage. A 60-inch storm sewer line runs east and west through the site from Brooklyn Boulevard east to in front of the north side of the school. The proposed new entry/administrative office area to be constructed would be built over this storm sewer line. The School District plans to relocate the storm sewer and a corresponding change in the easement document will need to be made to reflect the relocated utility. Other utilities, such as sewer and water, exist and no changes to these facilities are anticipated other than to accommodate the relocated shelter building. It is my understanding that this plan will not require Shingle Creek Watershed Management Commission review. The applicant has submitted a landscape plan showing existing and proposed new landscaping to be provided for the school and park. It should be noted that the landscape point system does not address schools or park facilities specifically in the evaluation criteria. The combined site is 11.58 acres in area. If we were to use the office criteria contained in the landscape point system, a total of 960 landscape points would be required. Considering existing landscaping and that being proposed, the total point value of the landscape plan would be 990 points. As mentioned previously, the plan comprehends establishing new landscape areas at various points around the site. A separation between the bus drop off area and the visitor parking area will accommodate a number of trees, shrubs and sod. Immediately to the east of the visitor parking area there will be a landscape area established with a new concrete walk and landscaping containing five new Red Maple trees. The green strip and area separating the parking lots include Redmond Linden and Red Maple shade trees as well as Allegheny Serviceberry and Japanese Tree Lilac decorative trees in the same area. In the green strip adjacent to the park parking lot is a new Redmond Linden to go along with an existing shade tree. Shrubs such as Andorra Juniper, Taunton Yew, Gro-Low Fragrant Sumac and American Cranberry Bush are located in green strip areas as well as in planting beds around the front and sides of the school building. Six Siouxland Poplar will be added to the south side of the parking lot at the rear of the building and Red Maple and Redmond Linden along with Allegheny Serviceberry trees are proposed for the expanded landscaped area along the east side of the building between the building wall and the new curb line for the faculty parking lot. Redmond Linden will also be used for island plantings in the visitor parking lot. Overall the landscape plan appears to be more than adequate for the site. 5-1-03 Page 3 The exterior treatment of the building additions will be a face brick to match the existing building exterior. A pre -finished metal panel fascia over the new entrance area will be established to match the existing fascia. The trash enclosure will be located at the south end of the existing building adjacent to the new addition. It will be a masonry structure to match the existing building with a solid, opaque gate. As indicated previously, the elementary school and park facilities are special uses in the R-1 zoning district and are subject to the Standards for Special Use Permits contained in Section 35- 220 of the City Ordinances. These Standards for Special Use Permits require that the proposed special use will promote and enhance the general public welfare and not be detrimental to or endanger the health and safety of the public; not be injurious to the use and enjoyment of other property in the immediate neighborhood, nor substantially diminish or impair property values; not impede the normal and orderly development of surrounding property; be designed so as to minimize traffic congestion on the public streets; and conform with the applicable regulations of the district in which it is located. We would comment that we believe the expansion of the Garden City Elementary School and the modification and reconfiguration of the Garden City Park area will not be detrimental to or endanger the public health, safety, morals or comfort. Furthermore, we do not believe that the use will be injurious to other property in the immediate vicinity nor will it diminish or impair property values within the neighborhood. In fact, the improvements proposed can be considered a benefit to surrounding properties. The expansion and the upgrading of park facilities can be considered a positive factor with respect to the surrounding area. We also believe that adequate measures have been or will be taken to provide proper ingress and egress and that the parking on the site is adequate for the uses provided. We do not see traffic congestion on public streets to be created with this redevelopment. The site and building plans submitted appear to conform with the applicable regulations of the district in which these properties are located. Finally, we believe the proposal meets all of the standards for special use permits contained in the City's Zoning Ordinance and recommend approval of the application. A public hearing has been scheduled with respect to this special use permit and notices have been sent to surrounding property owners. We believe the plans are in order and approval is recommended subject to the following conditions: 5-1-03 Page 4 The building plans are subject to review and approval by the Building Official with respect to applicable codes prior to the issuance of permits. 2. Grading, drainage, utility and erosion control plans are subject to review and approval by the City Engineer prior to the issuance of permits. 3. Any outside trash disposal facilities and rooftop or on ground mechanical equipment shall be appropriately screened from view. 4. The building additions are to be equipped with an automatic fire extinguishing system to meet NFPA standards and shall be connected to a central monitoring device in accordance with Chapter 5 of the City Ordinances. 5. B-612 curb and gutter shall be provided around all parking and driving areas. 6. An as -built survey of the property, improvements and utility service lines shall be submitted to the City Engineering Department. 7. All work performed and materials used for construction of utilities shall conform to the City of Brooklyn Center's current standard specifications and details. 8. Plan approval is exclusive of all signery, which is subject to Chapter 34 of the City Ordinances. 9. The special use permit is granted for the addition to the Garden City Elementary School and the modification and reconfiguration to Garden City Park as proposed in these development plans. Any expansion or alteration of the facilities not comprehended by this approval shall require an amendment to this special use permit. 10. The plans shall be modified to provide a concrete delineator for the 36 ft. wide driveway located at the northeast corner of the site. 11. Appropriate erosion and sediment control devices shall be provided on site during construction as approved by the City Engineering Department. 12. A new storm sewer easement shall be provided to protect the relocated 60 in. storm sewer. The appropriate portions of the existing storm sewer easement shall be vacated to reflect the realigned storm sewer location. 5-1-03 Page 5 MEMORANDUM DATE: April 29, 2003 TO: Ron Warren, Planning and Zoning Specialist FROM: Todd Blomstrom, Director of Public Works 'f PF SUBJECT: Garden City Elementary School Revised plans for the proposed improvements to Garden City Elementary School were reviewed for engineering and utility issues. The following plan sheets were submitted to the Public Works Department for review. 1. Site Survey, Sheet L1.0, dated February 26, 2003. 2. Preliminary Site Plan, Sheet L3.0, dated April 15, 2003 3. Grading and Utility Plan, Sheet L4.0, dated April 15, 2003 4. Landscape Plan, Sheet L5.0, dated April 15, 2003 5. First Floor Ref. Plan, Sheet Al. 1, dated April 3, 2003 6. Exterior Elevations, Sheet A4.1, dated April 3, 2003 The following comments are provided for your consideration. Water Supply Public water service is provided to the site from an 8-inch water main that extends from a 16- inch water main in Brooklyn Boulevard to a 16-inch water main in Xerxes Avenue. The water main crosses the site near the north property line and is within an existing easement as indicated on the site survey plan sheet. The plans indicate that water service to the building will continue to be provided through the existing water main along the west side of the building. The connection point of the existing service to the existing city water main is not indicated on the plans. Sheet L1.0 must be revised to show the service connection point to the existing water main. 2. The Owner should contact the City Fire Chief to discuss if additional hydrants are needed within the site due to the building expansion. Sanitary Sewer Public sanitary sewer service is provided to the site from a 15-inch sewer main that extends along the northern property line of the site. This sewer flows east along 65th Avenue, then south to Lift Station No. 1. GADepts\Public Works\Engineering\Development & Planning\Garden City Elem\Site Plan Review.doc l . The plans indicate that sanitary sewer service to the building will continue to be provided through the existing 8-inch service lateral extending from the north side of the building to the manhole in 651b Avenue North. Sheet L4.0 shows a second line labeled "ST" from the northwest corner of the building connecting to the existing sewer service. Storm sewer cross connections are not allowed into the sanitary sewer system. If this is an existing storm drainage pipe, it shall be disconnected with this project. 2. A 30-foot wide easement extends across the northern property line. The existing 15-inch sanitary sewer is located on the northern edge of the easement. The school is proposing the construction of a new bus entrance and parking lot over the top of the existing sewer. It is recommended that a utility easement extending 15 feet north of the existing sanitary sewer be prepared and recorded by the School District if any improvements are proposed over the top of the existing sanitary sewer pipe. 3. The City may require the installation of a water tight casting over the top of the existing manhole at the west driveway based on the review of the final plans. Storm Water Management Storm water runoff from this area of the city is conveyed by storm sewer to Shingle Creek. A 60-inch diameter trunk storm sewer extends through the site from Brooklyn Boulevard to the east. A 42-inch diameter storm sewer also extends through the site from the south property line to the connection with the above 60-inch diameter trunk sewer. Both of these storm sewer lines are located within existing 30-ft wide utility easements as indicated on the site survey plan sheet. 1. Sheet L1.0 does not show the location of the 60-inch diameter storm sewer pipe to the east of the intersection with the 42-inch diameter storm sewer pipe. Plan Sheet L1.0 shall be revised to accurately reflect the location of this section of storm sewer pipe. Plan Sheet L1.0 should be re -certified by a licensed land surveyor after the corrections are completed. 2. A portion of the 60-inch diameter storm pipe is proposed to be relocated to allow expansion of the building to the north. Pre -cast concrete manhole structures shall be placed at all changes in alignment of the pipe and at connection points. A revised engineering plan sheet shall be submitted to the City for review. The plan sheet shall include details of the relocation, including materials, profile, and alignment. 3. The existing easement for the portion of the 60-inch storm sewer to be relocated will need to be vacated prior to construction. A new easement for the relocated section of pipe must be prepared and recorded prior to construction. 4. The proposed southwest expansion of the building appears to encroach into the existing easement for the 42-inch diameter storm sewer crossing the site. Plan sheet L4.0 should be revised to show the existing and proposed easements. If the proposed building expansion encroaches significantly into the easement, the city may require relocation of a WDepts\Public Works\Engineering\Development & Planning\Garden City Elem\Site Plan Review.doc portion of the 42-inch pipe. Any portion of the easement that is used for building expansion will need to be vacated prior to construction. 5. Sheet L4.0 — Grading Note "N": At this time, the City has not agreed to be responsible for the cost of moving or adjusting existing city owned utilities that are necessary for the construction of the school building expansion. The School District may be responsible for up to 100 percent of the costs for relocating city owned utilities that are within existing easements. 6. The information submitted for review did not include data on the net increase in impervious surface for the site and the net increase in storm water runoff from the proposed improvements. This information should be submitted to the City for review. Grading and Erosion Control An erosion control plan must be prepared and submitted to the city for review and approval prior to initiating grading activities within the site. Street and Driveway Construction The Project includes the reconstruction and realignment of the west entrance to the school property. This driveway entrance is located along a 90-degree curve in the street. The reconfiguration creates what may appear to some as an uncontrolled 3-way intersection where west bound traffic on 651h Avenue may continue straight through the intersection and conflict with traffic traveling southbound on Drew Avenue North. The City will consider placement of a warning sign for the 90-degree right bend on 65th Avenue for west bound traffic. The City may require that a stop sign be placed at the exit point of the bus area driveway. 2. If the proposed driveways are to exceed 30 feet in width at the property line, a center median shall be added to separate ingress and egress traffic. The east side of the east driveway should be modified to taper into the curb line at a point west of the property corner. Trees, shrubbery, and other plant materials shall not be planted or maintained in such a manner as to obscure or impede the visual sightlines required to ensure the safe and efficient circulation of vehicles and pedestrians at the driveway openings and sidewalks. 4. It is recommended that the City and the School District enter into a maintenance agreement regarding the long-term maintenance of the parking lot pavement, snow removal, and grass mowing responsibilities.
