Sec. 20-63 Location of Flood Plain All land dellneatedon the map consisting of two pages entitled "Flood Insurance Rate Map, Town of Agawam, Massachusetts, Hampden County, Effective February 1 1978", as zone A-11, zone A-13, zone A-16, zone A, zone A-2, and zone B be included in the flood plain zone. This map is part of the Flood Insurance Study made for the Town of Agawam by the U. S. Dept. of Housing and Urban Development, Federal Insurance Administration. This Flood Insurance Study, dated February 1, 1978, with its accompanying Flood Insurance Rate Maps and Flood Boundary and Floodway Maps and any revision thereto are hereby adopted by reference and declared to be a part of this ordinance. In general terms the Flood Plain Zone is that land adjacent to the Westfield River, Connecticut River and its tributaries and Still Brook which lie at or below the elevation of the base flood (100 year flood) as determined in the Flood Insurance Study. The Flood Plain Zone shall be considered to be superimposed over other zones shown on the zoning map, as a recognition of the special hazards which exist in such areas. In Zone A areas where base flood elevation data is not provided by the Flood Insurance Study other available data from Federal, State, or other sources shall be utilized as a basis of determining the base flood level for purposes of enforcing the provision of this ordinance. Sec. 20-64 Permitted uses Inthose -portions o the Town so designated in paragraph 20-63 the following uses of land shall be permitted provided all necessary State and/or Federal Permits are of and the requirements of Sec. 20-66.7(f) are met: (1 Conservation of water, plants and wild life. (2 Legally permitted outdoor recreation not requiring development or landscape alteration in conflict with the purpose of this zone. (3) Grazing, forestry and other farms or agriculture consistent with the purposes of the zone. (4) Dwellings lawfully existing prior to the adoption of these provisions, however no building permits for substantial improvements or extensions shall be granted unless a Special Permit is granted by the Board of Appeals. (5) Proper operation and maintenance of dams and other water control devices. (6) Construction and maintenance of highways, streets, sidewalks, sewers, water mains, storm drains, utilities and related facilities by governmental agencies providing that the water and sewer systems and utilities be designed and constructed to minimize flood damage and to minimize or eliminate infiltration of flood water into the systems and discharges from the systems into flood waters. d (7) The following uses by special permit as provided by Sec. 20_66 if determined to be consistent with the purposes of this zone, said determination to be made by the Board of Appeals following application for a special permit by the landowner or owners: (a) Developed recreation facilities except buildings. (b) Utility lines and facilities. (c) Dams and other water control facilities if in an authorized plan by public agency or if built to create ponds for recreational or agricultural use. (d) Minor buildings incidental to permitted flood control, recreation, agricultural, etc. uses, and not exceeding 200 square feet in ground coverage, if constructed so as to not obstruct natural hydrological features and provided the requirements of section 20_6-VXe) relative to the elevation of the base flood are met. (e) in the floodway fringe, the numbered A zones, Zone A, and Zone B, that portion of the Flood Plain Zone outside the floodway the development of structures for residential use only if the lowest floor (including basement) is elevated to or above the level of the base flood (100 year flood) and the development of structures for non—residential use only if the lowest floor (including basement) is elevated to or above the level of the base flood (100 year flood) or together with the attending utility and sanitary facilities is flood proofed to or above the level of the base flood (100 year flood) provided a special permit is issued by the Board of Appeals. The term "Floodproofed" shall mean watertight with walls substantially impermeable to the passage of water and with structural components having the capability of resisting hydrostatic and hydro— dynamic loads and effects of buoyancy. Sec. 20-65 Prohibited uses.

(3) The digging or drilling of a well intended as a source of domestic water. (4) The installation of septic tank or leaching fields or on—site waste disposal systems. (5) The placement or location of a mobile home or the creation of mobile home parks or subdivisions.
