Summary
Any construction, grading, or manufactured home placement within Escondido's mapped special flood hazard areas needs a development permit from the engineering services department before work starts. Escondido Municipal Code Section 6-473.2 requires detailed site plans, utility layout, floodway location, and base flood elevation data with the application, and building without one is a misdemeanor under Section 6-472.2.
A development permit shall be obtained before any construction or other development, including manufactured homes, within any area of special flood hazard established in section 6-472.1. Application for a development permit shall be made on forms furnished by the City of Escondido.
