No development in the SFHA shall create a damaging or potentially damaging increase in flood heights or velocity or threat to public health and safety.
(A) Standards. Within the floodway identified on the flood boundary and floodway map or the flood insurance rate map, the following standards shall apply.
(1) No development shall be allowed which, acting alone or in combination with existing or future development works, will cause any increase in the elevation of the regulatory flood.
(2) For all project involving channel modifications or fill (including levees), the town shall submit the data and request to the Federal Emergency Management Agency to revise the regulatory flood data.
(B) A Zones. Within all SFHAs identified as A Zones (no 100-year flood elevation and/or floodway/floodway fringe delineation has been provided), the following standard shall apply. The total cumulative effect of the proposed development, when combined with all other existing and anticipated development, will not increase the regulatory flood elevation more than one-tenth of one foot and will not increase flood damages or potential flood damages.
(C) Public health standards in all SFHAs.
(1) No development in the SFHA shall include locating or storing chemicals, explosives, buoyant materials, flammable liquids, pollutants, or other hazardous or toxic materials below the flood protection grade, unless such materials are stored in a flood-proofed storage tank or building constructed according to the requirement of § 154.138.
(2) New and replacement sanitary sewer lines and on-site waste disposal systems may be permitted providing all manholes or other above ground openings are located above the FPG, or those which are located below the FPG are water-tight.
