Application No. 84036
Applicant: City of Brooklyn Park
Location: Crystal Airport Property
Request: Flood Plain Special Use Permit
The City of Brooklyn Park requests special use permit approval to alter the contour
of the floodway on the Crystal Airport property south of 63rd Avenue North. The
project would involve dredging of the ditch in this area and placement of spoil
alternately on either bank of the ditch. The purpose of the project is to facilitate
drainage in the area in Brooklyn Park between 63rd Avenue North and the I-94 freeway.
Depositing fill or the spoils from dredgingis a special use in the floodway zone. An
engineering analysis of the project is contained in a memo from Director of Public
Works, Sy Knapp (attached) .
Floodway special uses are subject to procedures set forth in Section 35-2184 and to
standards or requirements set forth in Section 35-2140 (see both sections attached) .
Many of these provisions relate to structures or development associated with struc-
tures rather than with alteration of the flood plain contours themselves. The
provisions that correspond most with the "standards for a special use permit," found
in Section 35-220, are the "Factors Upon Which the Decision . . . shall be Based" in
subsection 4 of 35-2184. Subsections a, b, e, i , and k seem to be relevant to the
proposed project.
The primary concern of staff is that the proposed ditch dredging will allow drainage
to flow faster thus leading to higher flood levels downstream in Brooklyn Center
and Robbinsdale. The conclusion of the hydrologic analysis by Barr Engineering is
that these effects will be minimal .
Accordingly, staff recommend that the special use permit application submitted by
the City of Brooklyn Park be approved subject to the conditions outlined in the memo
of Director of Public Works Sy Knapp, dated January 22, 1985.
