Commercial areas are designated C-1 (General Commercial), C-2 (Highway Commercial), and C-3 (Riverfront Enterprise Zone) — the latter a special economic development district along the Nanticoke River waterfront. Light industrial uses are permitted in the M-1 district.
Note on setbacks: Specific setback dimensions for each district are defined in Chapter 15. Contact the Seaford Code Department at (302) 629-9173 for setback requirements applicable to your property and proposed project.
