Federal Emergency Management Agency Administrator has not provided suffi. cient data to furnish a b...is for these regulations in a particular community, ' the conununity shall obtain, review and reasonably utilize data available from other Federal, State or other sources pending receipt of data from the Administrator. However, when special flood hazard area designations and water surface elevations have been furnished b~' the Administrator, they sh.JI apply. The symbols defining such special flood hazard designations are set forth In i 64.3 of this subchap- ter. In all cases the minimum requircM ments governing the adequacy of the flood plain management regulations for flood.prone are... adopted' by a particular community depend. on the amount of technical data formally provided to the conununity by the Ad- ministrator. Minimum standards !or communities arc as follows: (a) When the Administrator h... not defined the special flood hazard are... within a community, h... not provided water surface elevation data, and has not provided sufficient data to identify the floodway or coastal high hazard area. but the community has indicated the presence of such hazards by sub- mitting an application to participate In the Program, the community shall: (1) Require permits for all proposed construction or other development in the community, Including the place. ment of manufactured homes, so that it may determine whether such con- struction or other development is pro- posed within flood-prone areas; (2) Review proposed development to assure that all necessary permits have been received from those governmen- tal agencies from which approval is re- quired by Federal or State law, includ- ing section 404 of the Federal Water Pollution Control Act, Amendments of 1972,33 U.S.C. 1334; (3) Review all permit appllcations to determine whether proposed building sites will be re...onably safe from flooding. If a proposed building site is in a flood-prone area, all new construc- tion and substantial improvements shall (i) be designed (or modified) and adequately anchored to prevent flota~ tion, collapse, or lateral movement of' the structure resulting from hydrody- namic and hydrostatic loads, including Y60.3 the effects of buoyancy, (ii) be con- structed with materials resistant to flood damage, (Iii) be constructed by methods and practices that minimize flood damages, and (iv) be constructed with electrical. heating, ventilation, plumbing, and air conditioning equip. mer,t and other service faclllties that are designed andlor located so as to preveni water from entering or accu- mulating within the components during conditions of flooding. (4) Review subdivision proposals and other proposed new development. in- cluding manufactured home parks or subdivisions,. to determine whether such proposals will be reasonably safe from .flooding. If a subdivision propos- al or other proposed new development is in a flood-prone area, any such pro- posals shall be reviewed to assure that (i) all such proposals are consistent with the need . to minimize flood damage within the flood~prone area, m) all public utilities and facilities, such as sewer, gas, electrical, and water systems are located and con- structed to minimize or eliminate flood damage. and (ill) adequate drain. age is provided to reduce exposure to flood hazards; (5) Require within flood-prone are... new and replacement water supply systems to be designed to minimize or eliminate infiltration of flood waters into the systems; and (6) Require within nood~prone areas (i) new and replacement sanitary sewage systems to be designed to mini- mize or eliminate infiltration of flood waters into the systems and discharges from the systems into flood waters and (Ii) onsite waste disposal systems to be located to avoid impairment to them or contamination from them during flooding. (b) When the Administrator has des- ignated areas. of special flood hazards (A zones) by the publication of a com- munity's FHBM or FIRM, but h... nei- ther produced water surface elevation data nor identified a floodway or coastal high hazard area, the commu~ nity shall: (1) Require permits for all proposed construction and other developments including the placement of manufac- tured homes, within Zone A on the community's FHBM or FIRM; 261
