Jewell Engineering Consultants, PC worked with the Town to develop a long term master plan for the Stormwater Management Division. The multi-year planning process took into consideration the need to:
- involve local and regional stakeholders in development of the plan
- meet the Town’s stormwater
- related regulatory requirements
- provide fair, effective and efficient stormwater management services to residents and property owners in Chapel Hill
- provide baseline data and summaries of current stormwater related conditions, infrastructures and services, and
- recommend and prioritize action plans to mitigate flooding and improve water quality and stream integrity in the years ahead.

Watershed Assessments and Recommendations
There have been several studies of individual watersheds (drainage basins), water quality and ecological conditions in the Chapel Hill area, covered in detail under Water Quality. In addition, Jewell Engineering conducted two pilot sub-watershed evaluations and completed a pilot sub-watershed master plan report for sections of the Booker and Little Creek watersheds. Within the pilot study areas, Jewell Engineering:
- identified stream segments that may benefit from stream stabilization/restoration
- identified and prioritized potential sites for Best Management Practice (BMP) and retrofit opportunities
- performed hydrologic, hydraulic, and water quality/pollutant modeling
- evaluated the performance of major public drainage structures and develop recommendations for potential flood hazard reduction and drainage capital improvement projects
- identified potential nonstructural BMP opportunities
- developed an outline of recommendations for the scope and estimated costs of townwide subwatershed modeling and master planning to be performed in later phases, depending upon funding availability and actual Town needs.
Watershed and Sub-basin Maps
As part of the planning process, and to organize, analyze, and prioritize stormwater problems, we have created a map of drainage basins in the Chapel Hill area, all of which drain to Jordan Lake. These have been subdivided into sub-basins with very small drainage areas so problems can be isolated from larger basin issues and characteristics. Included in our geographic database are field-verified perennial, intermittent, and ephemeral streams. View major and minor basins/watersheds for the Town.
Town greenways are developed and managed by the Parks and Recreation Department. The original 1998 Greenways Master Plan has been updated to establish and maintain a system of linear open spaces that will help protect the environment of Chapel Hill; establish trails to promote recreation and regional greenway connectivity with neighboring jurisdictions; and to integrate relevant planning efforts to encourage a more active, bicycle and pedestrian friendly community. 2013 Greenways Master Plan
