Durham requires grading permits for land-disturbing activities under the UDO. Development projects must maintain existing drainage patterns and prevent adverse stormwater impacts on neighboring properties. Drainage criteria are specified in Section 8.1 of the Reference Guide for Development. All grading must comply with stormwater and erosion control standards.
Durham regulates grading and drainage through building and engineering codes. Grading permits required for excavation or fill over specified thresholds, typically 50 to 100 cubic yards. Site grading must direct drainage away from structures and not adversely affect neighboring properties. Drainage swales, French drains, and catch basins may be required. Retaining walls over 4 feet need engineering and separate permits. Compaction testing required for structural fill. Final grade must match approved plans. Property owners responsible for maintaining drainage facilities on their land.
Unpermitted grading: stop-work order and fines $250 to $2,500. Redirecting drainage to neighbors: corrective action required. Slope failure from improper grading: liability and remediation costs.
