The Downtown Design (DD) District is established to encourage bicycling, pedestrian, and transit-oriented development through regulations appropriate to the downtown area. It focuses on the form of the private and public realm instead of on use and intensity. Regulated through sub-districts, the standards encourage a vital downtown economy that enhances Durham’s position as a commercial, cultural and entertainment hub of the region while increasing livability. The DD District is intended to work in tandem with the Downtown Tier of the Durham Comprehensive Plan, Downtown Durham Master Plan and updates. Therefore the Downtown Tier boundary and the Downtown District boundary are the same.
