A Development Permit is required when a developer wishes to build in or alter the character of property identified in the 100-year regulatory floodplain.
If any proposed grading or improvements involve property in the floodway, a hydraulic flood study prepared by an engineer licensed in the State of Texas is required. The applicant's engineer will need to submit the study and supporting hydraulic data to the City's Engineering Department. This information will be reviewed by the Federal Emergency Management Agency (FEMA) as well as the City. The appropriate FEMA application forms and fees will also be required at the time of submission.
NOTE: A detailed study may also be required for development in areas that do not yet have a mapped floodway but have been identified as floodplain.
If the proposed grading or improvements only involve property in the floodplain fringe, a development plan and permit application (with the appropriate certifications) will need to be submitted to the Engineering Department for City review and approval only.
After construction, Elevation certificates will be required as applicable to the project.
