i <br /> Adjustme t to use its variance power to deal with the hardships caused by the higher standards.Another <br /> solution ' to utilize a"sliding scale" based on lot size or depth. For example, the City of Durham, in its <br /> Business ark zoning district,requires a 35-foot building setback for lots equal to or less than 10 acres in <br /> size. For ots greater than 10 acres,a 60-foot setback is required.For parking areas, the setbacks are 15 <br /> feet and 5 feet, respectively. <br /> When sing the lots which front on Old N.C. 86, the"break point" in terms of acreage versus ability <br /> to build a pears to be 2.0 acres.Thus,a standard combining the Willhoit and Durham standards might be <br /> a front back of 25 feet for lots 2.0 acres or less in size and 100 feet for lots greater than 2.0 acres in <br /> size. How er, lot depth appears to be more critical than lot size. The "break point" appears to be those <br /> lots w ' have depths (after a 20-foot right-of-way dedication) of approximately 170 feet. For example, <br /> in the D ' Manual case study, the lot depth after right-of-way dedication is 180 feet. The 25-foot front <br /> yard set enables the property to be developed, a setback which is 13.9% of the lot depth. The front <br /> yard boil setback standard thus recommended by staff is 15 percent of the lot depth(after the 20-foot <br /> right-of- y dedication), but not less than 25 feet and not more than 100 feet. For the case study, the <br /> standard Quid mean a front setback of 27 feet. For parking and storage areas, the setback standard <br /> would be five percent of the lot depth, but not less than 10 feet nor more than 100 feet. At the <br /> intersect: n with new collector streets,the standard would also apply for the first 200 feet of the collector <br /> road from a intersection rather than the step-down proposed by Commissioner Willhoit.These standards <br /> would le lots limited by size and depth to be developed without having to seek relief from the Board <br /> of Act ent. <br /> Front Rear/Side Lot Building <br /> Zo g Lot Area Setback Setback Width Height <br /> D at (SgFt) (Feet) (Feet) (Feet) (Feet) <br /> LC NA 15 15 75 25 <br /> N 2,000 50 NA 20 35 <br /> 40,000 35 NA 20 45 <br /> 0& 5,000 25 10 50 35 <br /> I-1 80,000 50 50 200 45 <br /> 1-2 20,000 50 NA 100 45 <br /> I-3 20,000 50 NA 100 45 <br /> Pro; lsll 25 10 <br /> ,Jed <br />
