Zoning File #1305 Page 2 of 3 The applicant's grading plan shows that a 10' level grade will be maintained along all sides of the stock pile. Staff would note that additional erosion control measures must be maintained while the 10,000 cubic yards is stored in the stock pile. Erosion control should be maintained at a minimum along the east, south and north of the stock piles. Applicant may select either staked hay bales or silt fence. In Glenn Cook's report, Exhibit G, he also advises that silt fencing should be placed near the southeast corner of the property to protect the downstream waterway. This should be installed prior to the commencement of the land alteration. Planning Commission members may remember that the applicant was advised to file the reauired MCWD permit application, Exhibit E, Mr. Larson noted the usual districts concerns in developments of this type. Briefly to review, he states the quality and quantity of run-off shall not be changed, erosion control to prevent transFort of sediments off -site during and after construction and prompt restoration of distu.bed areas with seed and mulch or sod. In Mr. Pallansch's letter, Exhibit F, he notes no real concern on Mr. Larsons part regarding the effects of the proposed addition on the site and suggests no major requirements will be made of the applicant as a result of the improvement. He also notes that they will follow all rules of the Minnehaha Creek Watershed District. We will ask Mr. Pallansch for any preliminary directives given to him by Mr. Larson at our meeting. Cook's report suggests the need for a siltation pond at the southeast corner of the property. The engineer has not suggested a specific size for the pond in his report, but has noted to staff that it should be approximately 1/2 to 3/4 of an acre and noted in addition, that it would be very advisable for both Cities to construct a retention or sediments pond between the shared lot lines. Staff would suggest that the City and the applicant work closely with the Minnehaha Creek Watershed District to determine the appropriate size of such a retension pond. Staff Recommendation To approve the Conditional Use Permit application of Washington Scientific, Inc. for the property located at 2605 West Wayzata Boulevard that would permit the temporar • stock piling of 10,000 cubic yards to be used in the final grading of the western elevations of the property per grading plans by the Vogt Corporation dated 5/19/88, revisions 6/29/88 based on the following findings: 1.

That the proposed temporary stock piling of fill and the final grading plans proposed wou'9 not be detrimental to the public health, safety, or welfare or materially injurious to properties or improvements in the vicinity. 3.
