Chapter 5. Flood Hazards.
§ 6–501. Review of building permit applications; design and construction requirements.
(a) The Mayor shall review all building permit applications for new construction or substantial improvements to determine whether proposed building sites will be reasonably safe from flooding. If a proposed building site is in a location that has flood hazard, the proposed new construction or substantial improvement (including prefabricated homes) must:
(1) Be designed (or modified) and anchored to prevent flotation, collapse, or lateral movement of the structure;
(2) Use construction materials and utility equipment that are resistant to flood damage; and
(3) Use construction methods and practices that will minimize flood damage.
(b)(1) The Mayor, pursuant to subchapter I of Chapter 5 of Title 2, may issue rules designating flood hazard areas in the District and requiring flood insurance as a condition of occupancy for the life of a new or substantially improved building in a flood hazard area.
(2) For the purposes of this subsection, the term:
(A) "Flood hazard area" means an area designated as:
(i) A special flood hazard area or other area of flood hazard on the then-current flood insurance rate map for the District of Columbia issued by the Federal Emergency Management Agency; or
(ii) An area of flood hazard, as determined by the Mayor by rule.
(B) "Substantially improved building" means any building which has undergone any repair, alteration, addition, or improvement, the cost of which equals or exceeds 50% of the market value of the building before the improvement or repair was started.
§ 6–502. Review of subdivision and other new development proposals.
The Mayor shall review subdivision proposals and other proposed new developments to assure that:
(1) All such proposals are consistent with the need to minimize flood damage;
(2) All public utilities and facilities, such as sewer, gas, electrical, and water systems are located, elevated, and constructed to minimize or eliminate flood damage; and
(3) Adequate drainage is provided so as to reduce exposure to flood hazards.
§ 6–503. Design of water and sanitary sewage systems; location of on-site waste disposal systems.
The Mayor shall require new or replacement water systems and sanitary sewage systems to be designed to minimize or eliminate infiltration of flood waters into the systems and discharges from the systems into flood waters, and require on-site waste disposal systems to be located so as to avoid impairment of them or contamination from them during flooding.
§ 6–504. Review of excavation, grading, filling, or construction permit applications; mudslide hazards.
The Mayor shall review each permit application for any excavation, grading, fill, or construction to determine whether the proposed site and improvements will be reasonably safe from mudslides. If a proposed site and improvements are in a location that may have mudslide hazards, a further review shall be made by persons qualified in geology and soils engineering; and the proposed new construction, substantial improvement, or grading must:
(1) Be adequately protected against mudslide damage; and
(2) Not aggravate the existing hazard.
§ 6–505. Annual report.
The Mayor shall submit an annual report before April 1st of each year to the Council to advise the public of progress made under the National Flood Control Program.
