Department also recommends turn lanes as part of their review. Therefore, the applicant has added these to the plan set. Off-Street Loading Areas: City code sets forth standards for loading dock areas, and the proposed plan is satisfactory to city staff and the City Engineer. Parking: The proposed plans indicate a total of 86 stalls of parking for both the Bill's Superette and the G -Will Liquors site. City code requires one stall per 200 square feet of building area (with a 10 percent credit for unusable floor area), resulting in a total of 99 required stalls. The applicant is proposing "proof -of parking" areas for the deficient 12 stalls. In an effort to reduce impervious surfaces and mitigate storm water runoff, city code allows for "parking deferment" when evidence is provided by the applicant to suggest that the required number of parking stalls are not needed. The applicant has constructed several stores and has provided evidence from these stores that the parking demand is lower than city code requires. Staff and the Planning and Zoning Board are comfortable with the level of parking proposed and allowing a deferment of the remaining 21 stalls. The site plan does not indicate a perimeter curb along the sidewalk/walkway areas adjacent to the building. The applicant has requested this to reduce liability and increase ease for people using the area. Bollards are proposed to provide pedestrian and vehicle separation. Surface Water Management /Pollution Prevention: City code restricts impervious surfaces to no more than 75 percent of the site, which the proposed plan meets. Stormwater is proposed to be routed to an infiltration basin located in the southwest corner of the site. Stormwater management comments were provided to the applicant in the engineering review memo, dated November 5, 2012. The majority of these comments were addressed by the applicant in revised plans received by the City on November 19, 2012. However, two concerns in the engineering review memo were not addressed in the revised documents: • Runoff is directed across the south driveway, which could lead to icy conditions when thawing and freezing occurs. • The proposed swale on the east property line may not have adequate capacity during large rainfall events. This could cause channelized runoff to enter the property east of the site during large rainfall events. Based on discussions with the applicant's engineer (MFRA), these two concerns will be addressed by installing a culvert under the south driveway and by increasing the depth of the proposed swale on the east property line. With these two modifications to the plans, we feel that the project is able to meet or exceed the city's stormwater management requirements. The Rice Creek Watershed District will require a permit for the storm water management on this site, and have submitted several comments regarding this review. An operation, inspection, and maintenance agreement should be completed that indicates the land owner is responsible for the stormwater facilities. Grading /Drainage: For all motor fuel stations, oil /grit separators are required as a mechanism for limiting polluted run -off from entering the storm water system. The applicant has submitted satisfactory plans for the separation of oil /grit, per the city code. The applicant is required to provide proof of NPDES permit prior to commencing with grading.
