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) 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 similar works, will cause any increase in the elevation of the regulatory flood.
(2) For all projects involving channel modifications or fill (including levees), the town shall submit a request to the Federal Emergency Management Agency to revise the regulatory flood data.
(B) 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) (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 storage tank or flood-proofed building constructed according to the requirements of §§ 153.07 and 153.08 of this chapter.
(2) New and replacement sanitary sewer lines and on-site waste disposal systems may be permitted providing all manholes or other above ground openings located below the FPG are water-tight.
