Final S itc P lan Re view - Gateway Re tail Building To wn Center 3 rd Addition October 7, 2004 Page 2 of 8 Floor Area Ratio: Lot 1 of Town Center 3rd Addition is proposed to accommodate the grocery store, fuel pump islands, and 4 other commercial structures, two of which will 'be developed in the first phase with the grocery store. The area of Lot 1 is' 388,677 square feet. The minimum floor area ratio is .5 or 194,338 square feet in this case. The total area of the footprint of the grocery, store is being increased from the preliminary site plan to 62,000 sq. ft.', it is presumed that the fuel pump island remains at 430 sq. ft.; the 1,777 sq. foot car wash is being eliminated; comer retail store building is reduced from the preliminary site plan to 13,000 sq. ft.; and two other commercial buildings have been increased to 20,000 square feet. The total amount of building ibotprint proposed at preliminary site plan was 93,207; the proposed building footprint total ~br Lot 1 on the final plans is 95,430 square feet. This is approximately a 2,200 square increase in building square footage from the preliminary site plan. However, the proposed building coverage is still deficient of .5 ratio and has been addressed with the variance to floor area ratio approved by the Board of Adjustment on August 5, 2004. Storm Water Plan. We offer the following comments: The outlet structure for the pond shows a 2 ft orifice.. This orifice is not reflected in the current storm water model. · The details include an emergency overflow using tuffturf. This is not called out on the plans. Review of the grading plan shows that the lowest point on the rim of the' pond is at least 1 foot above the floor elevation of the building closest to the pond. Please submit information on the maximum probable pond elevation. Assumptions should include partial or complete blockage of the outlet and should be clearly called out in the summary. · The t00 yr water elevation on the grading plans does not match the SWMM model. · Inlet protection must be installed on all storm'sewer structures as shown on the plans. · Storm water ponding is done in regional ponds for RTC. Each site must implement Best Management Practices ~br storm water quality. Please provide details on the BMP's for this site. Particular attention must be made to the storm lines draining the filling station element. Grading Plan: We offer the following comments on the grading plan. The italicized comments were issued in the July 2004 review and have not been addressed in the current plans. · The minimum allowable slope on bituminous surfaces must be 1.0%. The minimum slope on concrele surfaces is 0.5% · 5'pot elevations should specify top or bottom of curb. · ,.~[aximum cross slope in drive aisles should be 2.0°40. · Signed engineeri;qg drawings will be need to be submitted to the building inspection department for review prior to approval of this concept. · Grade transitions should be smoothed Out, the current plans show grade changes of 2%+ on d!fferent sictes of contour lines. · The grades across islands must be reviewed. We observed grade, differences of more than l toot across narrow areas of islands. · The 100 yr water elevation on the grading plans does not match the SWMM model.
