Environmental and Historic Preservation (EHP) refers to FEMA’s review process for ensuring the protection and enhancement of environmental, historic, and cultural resources, as required by Federal environmental and historic preservation laws and Executive Orders.  The EHP review process ensures HMA program and grant compliance with 44 C.F.R. Parts 9, Floodplain Management and the Protection of Wetlands and Part 10, Environmental Considerations, and with all applicable EHP laws, such as the National Environmental Policy Act (NEPA), the National Historic Preservation Act (NHPA), the Endangered Species Act (ESA), and their implementing regulations; and with E.O. 11988 (Floodplain Management), E.O. 11990 (Protection of Wetlands) and E.O. 12898 (Environmental Justice).
EHP considerations may require identifying alternate project types and/or locations and, as necessary, modifying the project.  Two key considerations are whether the proposed project is located in an area that has endangered or threatened species or critical habitat and whether the proposed project might impact historic or cultural resources.  If the project could result in adverse impacts to those resources, it might be necessary to change the scope of the project to avoid those impacts or to incorporate mitigation measures to minimize the impacts to those resources.
