ORANGE COUNTY PLANNING DEPARTMENT 4 306F REVERE ROAD HILLSBOROUGH, NORTH CAROLINA 27278 :-1,e' MEMORANDUM To: Board of County Commissioners John Link, County Manager From: Marvin Collins, Planning Director N Mary Willis, Planner III/Current Planning Date: November 10, 1993 Subject: Proposed Watershed Protection Standards Copies: Geoffrey Gledhill, County Attorney David Stanch, Planner II/Comprehensive Planning At your November 1, 1993 meeting, a number of questions were asked concerning the proposed watershed protection standards. This memorandum lists those questions, provides answers, and, where necessary, Staff recommendations concerning each. 1. Will the adoption of impervious surface ratios (sliding scale or set ratios) require additional Staff time for calculation and monitoring purposes? The answer to this question is no. As part of its work on the University Lake watershed, Staff developed a spreadsheet template (see Attachment #1) to provide a quick and efficient means of performing such calculations. Information needed for this purpose is readily available from site plans submitted by applicants for building permits. In terms of monitoring impervious surfaces on an individual site or for an entire watershed, ORPERMIT, the County's computerized building permit system, is being revised to require the amount of impervious surface to be shown on the permit form (see Attachment#2). With this information in the system, computer generated reports can be produced which indicate the amount of new impervious surface for a site, area or watershed for any period of time. Plans are to complete revisions to ORPERMIT before the end of November, and, in any case, before the January 1, 1994 effective date. 2. What are the implications of adopting set impervious surface ratios; e.g., 6% for two- acre lots and 12% for one-acre lots, on a property owner's ability to build a typical single-family house?
