Y. "New mobile home park" means a parcel (or conti- gous parcels) of land divided into two or more mobile home lots for rent or sale for which the construction of facilities for servicing the lot (includj.ng, at a minimum, the installation of utilities, either final site grading or the pouring of concrete pads, and the construction of streets) is completed on or after the effective date of this ordinance. Z. "Obstructionll means sandbars formed by the natrual flow of a watercourse, temporary structures, planks, snags, and debris in and along an existing channel which cause a flood hazard. AA. 1I0rdinary high water mark" means the highest point on the bank of a normal stage channel at which the water level has been for a sufficient period of time to leave a definite mark. BB. "Reach" is a hydraulic engineering term to describe longitudinal segments of a stream or river. A reach will generally include the segment of the floodplain where flood heights are primarily controlled by man- made or natural floodplain obstructions or restrictions. In an urban area, the segment of a stream or river between two consecutive bridge crossings would most likely be a reach. CC. "Regulatory floodway" means the channel of a river or other watercourse and the adjacent land areas that must be reserved in order to discharge the base flood without cumulatively increasing the water surface elevation more than a designated height. DD. "Start of construction" means the first placement of permanent construction of a structure (other than a mobile home) on a site, such as the pouring of slabs or footings or any work beyond the stage of excavation. Permanent construction does not include land prepara- tion, such as clearing, grading, and filling, nor does it include excavation for a basement, footings, piers or foundatjlons or the erection of temporary forms; nor does it include the installation on the property of accessory buildings, such as garages or sheds not occupied as dwelling units or not as part of the main structure. For a structure (other than a mobile home) without a base- ment or poured footings, the" start of construction" includes the first permanent framing or assembly of the structure or any part thereof on its piling or founda- tion. For mobile homes not within a mobile home park, "start of construction" means the affixing of the mobile home to its permanent site. For mobile homes within mobile home parks, "start of construction" is the date on which the construction of facilities for servicing the site on which the mobile home is to be affixed (including at a minimum, the construction of streets, either final site grading or the pouring of concrete pads, and installa- tion of utilities) is completed. EE. "Storage capacity of a floodplain" means the volume of space above an area of floodplain land that can be occupied by floodwater of a given stage at a given time, regarless of whether the water is moving. Storage capacity tends to reduce downstream flood peaks. -4-
