How rules apply to floodplains, wetlands and historic resources
Projects in or near FEMA-designated flood zones, jurisdictional wetlands, or properties listed as historic resources may trigger additional studies (floodplain development evaluation, wetland delineation, cultural resources assessment) and mitigation measures. Local ordinances often require avoidance first, then minimization and mitigation when impacts cannot be avoided. The municipal code provides the controlling local standards and procedural requirements; consult the code and Planning Division for project-specific interpretation.[1]
- Required studies: wetland delineation, hydrology/flood study, and historic resource survey where applicable.
- Mitigation: may include preservation, on-site restoration, off-site mitigation or in-lieu fees.
- Prohibitions: unauthorized fill, grading or removal of wetlands or historic fabric is typically prohibited and may be subject to enforcement.
