3102.4Each agency identified in this Chapter shall be responsible for the implementation of the substantive requirements of this Chapter. For example, the provisions of this Chapter regarding structural requirements are regulated and enforced by DCRA under the District’s Building Code, while land disturbing activities such as excavation, filling, grading, and determination of base flood elevations and impacts on flood elevations, continue to be regulated and enforced by DDOE. Applicants for construction and development in the flood hazard areas are required to obtain a building permit from DCRA, the application for which will be reviewed by the relevant agencies identified in this Chapter for compliance with this Chapter. Subdivision applications will be filed with DCRA, and then sent to DDOE for review of the SFHA boundaries. If a subdivision is greater than fifty (50) lots or five (5) acres, whichever is the lesser, then the applicant will be required to provide base flood elevation data with the subdivision application to be reviewed by DDOE.
