Site Development Permit
A Site Development Permit is required for projects that involve grading and/or filling activities. A Site Development Permit is also required for any development in the floodplains and wetlands and for projects that may result in soil erosion and/or drainage concerns. A Site Development Permit may be issued in conjunction with a Building Permit or may be issued independently depending on the type of activity.
A Site Development Permit is issued to assure that:
- Development is in compliance with the Unified Development Ordinance and Federal and State regulations (e.g., wetlands, floodplains and erosion control).
- Harmful environmental effects and negative impacts are minimized or mitigated.
