In August 2009, the North Carolina General Assembly passed the Jordan Lake Nutrient Management Strategy, commonly known as the Jordan Lake Rules. The rules mandate reducing pollution from wastewater discharges, stormwater runoff, agriculture and fertilizer application in both new and existing development within the Jordan Lake watershed. New buffer (streamside vegetation) requirements will affect how property owners maintain and develop their land.
All waterways in Chapel Hill and its planning jurisdiction flow into the Upper New Hope Arm of Jordan Lake. This area of the lake experiences frequent algal blooms due to overloads of nitrogen and phosphorous. The algal blooms can cause taste and odor problems in drinking water, kill or stress aquatic life, and can release toxins into the water. Riparian buffers are important in providing vegetation to filter stormwater runoff and to stabilize streambanks. They reduce erosion and sedimentation and the corresponding pollutants that flow into streams and the lake.
NEW DEVELOPMENT REQUIREMENTS A text amendment was approved on October 24, 2012 adding Section 5.19 - Jordan Watershed Stormwater Management for New Development to the LUMO. The effective date is December 1, 2012.
