This bill, titled the Coastal Broadband Deployment Act , aims to expedite the deployment and modification of communications facilities by exempting certain projects from extensive federal review processes. It specifically targets projects carried out entirely within a floodplain , as defined by federal regulations, that require authorization from the Federal Communications Commission (FCC). Under this legislation, such covered projects would no longer be subject to the requirements of the National Environmental Policy Act (NEPA), meaning they would not be considered a major federal action requiring environmental impact statements. Additionally, these projects would be exempt from the National Historic Preservation Act (NHPA), removing the need for historical preservation reviews. This measure is intended to streamline the development of broadband infrastructure in these specific geographic areas.
