Stormwater Management
Chapel Hill operates a Phase II NPDES MS4 stormwater program codified in Town Code Chapter 23 (Water, Sewers and Drains) and the Land Use Management Ordinance (LUMO) Appendix A, Article 5 (Sections 5.4 and 5.19). The Town established a Stormwater Management Utility in 2004; the current Equivalent Rate Unit (ERU) charge is $34.97 per year per 1,000 square feet of impervious surface, billed on the annual Orange County property tax bill. Chapel Hill lies entirely within the B. Everett Jordan Reservoir watershed (Upper New Hope arm of the Cape Fear River basin) and is therefore subject to the Jordan Lake Rules (15A NCAC 02B .0262 to .0273).

Heavy RestrictionsErosion Control
Erosion and sedimentation control in Chapel Hill is enforced under the NC Sedimentation Pollution Control Act of 1973 (NCGS Chapter 113A, Article 4) and the Town's Soil Erosion and Sedimentation Control Ordinance in Chapter 5 (Article V) of the Code of Ordinances. All projects that disturb more than 20,000 square feet within Chapel Hill or its Extraterritorial Jurisdiction (ETJ) require an approved Erosion and Sedimentation Control Plan and Permit issued by NC DEQ or Orange County Planning and Inspections. Single-family residences and projects below the 20,000 sq ft threshold must still install minimum erosion control measures (construction entrance, silt fencing on downhill slopes). Enforcement is handled jointly with Orange County Erosion Control.

Heavy RestrictionsFlood Zones
Chapel Hill regulates floodplain development through the Resource Conservation District (RCD) overlay codified in LUMO Appendix A Section 3.6.3 - established by the Town in 1985 specifically to protect stream corridors and prevent property damage from flooding - and through participation in the National Flood Insurance Program (NFIP). The Town uses FEMA Flood Insurance Rate Maps produced through the North Carolina Floodplain Mapping Program (NCFMP). North Carolina applies a 2-foot freeboard above the Base Flood Elevation as the regulatory flood protection elevation for non-coastal communities. Regulated watercourses include Bolin Creek, Booker Creek, Morgan Creek, and Little Creek - all tributaries to the Upper New Hope arm of Jordan Lake.

Heavy RestrictionsGrading & Drainage
Grading and drainage in Chapel Hill are regulated through LUMO Appendix A Section 5.4 (Stormwater Management) and Section 5.19 (Stormwater Quality and Peak Flow Rate Requirements), the Town's NPDES Phase II MS4 permit, and the Jordan Watershed Riparian Buffer Protection rules at LUMO Section 5.18 that implement 15A NCAC 02B .0267. The Jordan Lake riparian buffer is 50 feet wide measured from the top of bank of all intermittent and perennial streams, divided into Zone 1 (inner 30 ft, most restrictive) and Zone 2 (outer 20 ft). Chapel Hill is one of the most rigorous adopters of the Jordan buffer rules in the state and continues to enforce them despite the suspension of the related new-development rule .0265.
