7 Per City Code Section 1007.044(6), day care facilities require one (1) space for each 300sf of floor area. Floor area is 10% of the gross area. Gross Area -10% Floor Area/300 Total Spaces Required Total Spaces Provided 16,941sf 1694 15,247sf /300 = 51 54 Sheet C1, Site Plan indicates 51 paved parking stalls and 3 ADA parking stalls for a total of 54 parking stalls. Three (3) spaces are being constructed on Outlot A as part of a future shared parking lot. These will be covered by a recorded Shared Driveway and Parking Access Agreement. Grading Plan and Stormwater Management Per the City Engineer Memo dated May 3, 2023: Stormwater from the existing 4.22 acre vacant lot area drains to storm sewer along Apollo Drive (CSAH 12), which eventually drains to a city maintained pond in the northwest quadrant of the Apollo Drive (CSAH 12) and Lilac Street intersection. The project is proposed to add approximately 1.02 acres of impervious surface for the childcare facility, parking lot, and entrance drive, according to the Stormwater Management Plan. The applicant is proposing two infiltration basins to meet the runoff rates and water quality standards. A geotechnical evaluation report prepared by Chosen Valley Testing, Inc. was submitted with the application. The report included soil borings which indicated that the soils in the area consist of poorly graded sand with silt. Groundwater was not observed in the borings. The applicant used a HydroCAD model based on the Atlas 14, 24-hour storms to design the storm sewer and infiltration basins. The proposed improvements are designed to reduce site runoff rates for the 2-, 10-, and 100-year rainfall events. Runoff rates for the 10-day snow melt event were not provided at this time and are not required as basin outlets are below the 100-year HWL. Pre- and Post- Development Discharge Rates (cfs) Condition 2-Year 10-Year 100-Year 10-Day Snowmelt Existing 0.67 2.82 9.56 Not provided Proposed 0.20 1.07 7.18 Not provided
