Chapter 160 – Flood Plain Regulations

6. “Expansion of existing factory-built home park or subdivision” means the preparation of additional sites by the construction of facilities for servicing the lots on which the factory-built homes are to be affixed (including, at a minimum, the installation of utilities, the construction of streets, and either final site grading or the pouring of concrete pads). 7. “Factory-built home” means any structure designed for residential use which is wholly or in substantial part made, fabricated, formed, or assembled in manufacturing facilities for installation or assembly and installation on a building site. For the purpose of this chapter, “factory-built home” includes mobile homes, manufactured homes, and modular homes and also includes “recreational vehicles” which are placed on a site for greater than 180 consecutive days and not fully licensed for and ready for highway use. 8. “Factory-built home park” means a parcel or contiguous parcels of land divided into two or more factory-built home lots for sale or lease. 9. “Flood” means a general and temporary condition of partial or complete inundation of normally dry land areas resulting from the overflow of streams or rivers or from the unusual and rapid runoff of surface waters from any source. 10. “Flood elevation” means the elevation floodwaters would reach at a particular site during the occurrence of a specific flood. For instance, the 100-year flood elevation is the elevation of floodwaters related to the occurrence of the 100-year flood. 11. “Flood Insurance Rate Map (FIRM)” means the official map prepared as part of (but published separately from) the Flood Insurance Study which delineates both the flood hazard areas and the risk premium zones applicable to the community. 12. “Flood plain” means any land area susceptible to being inundated by water as a result of a flood. 13. “Flood plain management” means an overall program of corrective and preventive measures for reducing flood damages and promoting the wise use of flood plains, including but not limited to emergency preparedness plans, flood control works, flood proofing, and flood plain management regulations. 14. “Flood proofing” means any combination of structural and nonstructural additions, changes, or adjustments to structures, including utility and sanitary facilities which will reduce or eliminate flood damage to such structures. 15. “Floodway” means the channel of a river or stream and those portions of the flood plains adjoining the channel, which are reasonably required to carry and discharge floodwaters or flood flows so that confinement of flood flows to the floodway area will not cumulatively increase the water surface elevation of the base flood by more than one foot. 16. “Floodway fringe” means those portions of the flood plain, other than the floodway, which can be filled, leveed, or otherwise obstructed without causing substantially higher flood levels or flow velocities. 17. “Historic structure” means any structure that is: A. Listed individually in the National Register of Historic Places, maintained by the Department of Interior, or preliminarily determined by the Secretary of the Interior as meeting the requirements for individual listing in the National Register; B. Certified or preliminarily determined by the Secretary of the Interior as contributing to the historical significance of a registered historic district or a district preliminarily determined by the Secretary to qualify as a registered historic district;
