JORDAN LAKE WATERSHED <br />be allowed where no practicable alternative exists. <br />d) Use and Storage of Hazardous Materials <br />An inventory of all hazardous materials used and stored in the watershed must be maintained. <br />A containment plan in the event of spill of failure, and appropriate safeguards against <br />contamination are required. <br />M. ISSUES <br />A. Orange County was the only jurisdiction to request a classification of WS II. <br />Chatham County (including Pittsboro) requested WS M. Durham (City and <br />County) and Chapel Hill requested WS rv. The Town of Carrboro does have a <br />small area of jurisdiction along Smith Level Road. <br />B. Existing density standards are more restrictive than those proposed in the State Rules. <br />Local jurisdictions do have the authority to adopt or maintain standards which exceed the <br />minimum required by the State Rules. <br />C. The watershed is not now classified as a protected watershed. The Land Use Plan and <br />the Zoning Ordinance would have to be amended to define the watershed boundary. A <br />new or revised zoning district and/or zoning overlay would have to be created to specify <br />the new standards. The density standards would not require revision, as they are already <br />more restrictive than required for a WS IV watershed. Although this watershed is not <br />classified as a protected watershed, stormwater controls and stream buffers are required <br />through the County Subdivision Regulations. <br />D. There is currently no impervious surface limit. This could create some problems in <br />development of existing lots which are smaller than 2 acres, particularly those which <br />would require long driveways to access building sites. <br />E. The minimum width of stream buffers would increase from 50, to 100% This could have <br />and impact on existing lots that have limited buildable area, particularly those created <br />Prior to adoption of zoning regulation (1967) which do not meet current minimum lot <br />size requirements. <br />F. Operation and maintenance of detention ponds or other engineered stormwater controls <br />used to exercise the high -density option will require oversight by the County. This will <br />require development and implementation of a monitoring program by the Erosion Control <br />Division and/or County Engineer. <br />G. The University of North Carolina at Chapel Hill has expressed concern over the effect <br />of the watershed standards on future campus construction. Much of the UNC south <br />campus falls within the protected arc. <br />51 <br />
