Q5 Pam p• <br /> from the site as it is now. Shanklin asked if it was concentrated <br /> at one point and asked about the 125.44 reference. Post responded <br /> the latter figures is what it will be at the worse possible mount <br /> if all lots are developed at maximum impervious surface levels. <br /> Shanklin asked if this reflected the greatest runoff at peak develo; <br /> ment. Post responded affirmatively. Kizer noted this was the <br /> potential runoff if nothing was impounded. Post indicated the <br /> detention proposals addressed the site as a whole though runoff <br /> controls affected certain lots and certain sections of the <br /> development. <br /> Greenberg inquired about the schedule for stormwater improvements. <br /> Smith responded they are to be in place before permits are issued. <br /> Greenberg inquired about stream buffer calculations. Faircloth <br /> responded that they varied with width and were calculated on the <br /> basis of the formula in the ordinance. He continued that the <br /> Carrboro ordinance called for 100' for streams feeding directly <br /> into the lake and 50' for lesser streams. He added slope was a <br /> real factor only with regards to Phils and Neville Creeks. <br /> Gordon inquired if there was any necessity to improve the ordinance <br /> due to lack of specificity. Faircloth answered affirmatively. <br /> MOTION; Pearson moved approval with staff recommendations. Shanklin seconded <br /> the motion. <br /> VOTE: 5 in favor; Greenberg opposed • <br /> Motion carried. <br /> TM 5c: Mel Oak Estates Preliminary Plat. <br /> Presentation by Coutu. <br /> The property in question is located in Chapel Hill Township on <br /> SR 1942, Jones Ferry Road. It is referenced as Lot 2 of Tax <br /> Nan 118 and is bordered by ? icultu -Residential land. The <br /> tract is designated as Ag_^icultura1-Residential in the Land Use <br /> Plan and zoned Agricultural-Residential. <br /> There are seventeen (17) lots proposed out of a 19.53 acre tract. <br /> The Traximr mn lot size proposed is 96,000 sq. ft. or 2.2 acres while <br /> the minimum lot size is 40, 000 sq. ft. or .92 acres. <br /> The property is in University Lake Natershed so the impervious <br /> surface ratio. applies. See Table 1 for impervious surface ratio per <br /> lot. <br /> To meet the stor^rwater runoff requirements, the engineer proposes <br /> a detention pond on Lot 4 with the following calculations: <br /> Computed Discharge Undeveloped = 55 ft.3/second <br /> Computed Discharge Developed = 67 ft.3/second <br /> Additional Discharge = 12 ft.3/second <br />
