PROPOSED ORDINANCE AMENDMENT <br />ORDINANCE: SUBDIVISION REGULATIONS <br />REFERENCE: SECTION IV -B -1 LOT STANDARDS <br />ORIGIN OF AMENDMENT: <br />X Staff <br />X_ BOCC <br />175 <br />Planning Board <br />Public Other: <br />STAFF PRIORITY RECOMMENDATION: X,High Middle Low <br />Comment : <br />PUBLIC HEARING DATE: August 30, 1990 <br />PURPOSE OF AMENDMENT: <br />To revise lot standards to reflect the minimum lot sizes needed to <br />accommodate various types of wastewater disposal and water supply. <br />IMPACTS /ISSUES: <br />This amendment was originally proposed to formalize a policy requiring <br />twice the minimum lot size for a lot which provides a septic easement <br />for another lot. It was presented for public hearing on November 27, <br />1989. The Board of Commissioners directed staff to receive comments <br />from the Orange County Board of Health regarding area requirements for <br />wells and septic tanks so that the policy might be re- evaluated. The <br />current policy of requiring twice the minimum lot area for a lot <br />providing a septic easement for a different lot was established during <br />approval of the Preliminary Plan for Morelands Subdivision. However, <br />that policy was never translated into a development standard in the <br />Subdivision Regulations. <br />Another aspect of the amendment addresses situations where a lot will <br />be served by public water or public sewer, but not both..That situation <br />is not now addressed in the subdivision regulations. <br />The Orange County Division of Environmental Health indicated that a <br />septic tank drain field and repair are can be located on an area of <br />about one - fourth (1/4) acre (10890 square feet) under conditions of <br />ideal soils and topography. An area of about 3/8 acre (16335 square <br />feet) is more typical. It is required that the well be located at <br />least 100 feet from the septic tank or drain field, and at least 50 <br />feet from any structure. Setbacks of at least ten (10) feet are <br />required for both well and septic tank /drain field. <br />The attached diagrams provide examples of minimum lot sizes that would <br />be necessary to meet requirements of Environmental Health, and setback <br />and frontage requirements for rectangular lots in the unzoned <br />townships. The absolute minimum size needed for a lot would depend on <br />the specific location of the well, septic tank, residence, and <br />driveway, and could be larger or smaller than any figure chosen as a <br />
