Substantial improvement means any reconstruction, rehabilitation, addition to or other improvement of a structure, the cost of which equals or exceeds 50 percent of the market value of the structure before the start of construction of the improvement. This term includes structures which have incurred substantial damage, regardless of the actual repair work performed. The term does not, however, include either: A. Any project for improvement of a structure to correct existing violations of state or local health, sanitary, or safety code specifications which have been identified by the local code enforcement official and which are the minimum necessary to accessibility and assure safe living conditions; or b. Any alteration of a historic structure, provided that the alteration will not preclude the structure's continued designation as a historic structure. Threshold Planning Quantity (TPQ) is a quantity designated for each chemical on the list of extremely hazardous substances that triggers notification by facilities to the State that such facilities are subject to emergency planning requirements. Variance is a grant of relief to a person from the requirement of the ordinance when specific enforcement would result in unnecessary hardship. A variance, therefore, permits construction or development in a manner otherwise prohibited by this ordinance. (For full requirements, see Section 60.6 of the NFIP regulations.) Violation means the failure of a structure or other development to be fully compliant with the community's floodplain management regulations, including without limitation the provisions of this chapter and applicable provisions of 44 CFR (National Flood Insurance Program Regulations) and state regulations. A structure or other development without the elevations certificate, other certifications, or other evidence of compliance required in 44 CFR Section 60.3(6)(5), (c)(4), (c)(10), (d)(3), (e)(2), (e)(4), or (e)(5) is presumed to be in violation until such time as that documentation is provided. Water surface elevation means the height, in relation to the North American Vertical Datum (NAVD) of 1988 (or other datum, where specified), of floods of various magnitudes and frequencies in the floodplains of coastal or riverine areas. Watercourse means a channel, natural depression, slough, artificial channel, gulch, arroyo, stream, creek, pond, reservoir, or lake in which storm runoff and floodwater flows either regularly or infrequently. This includes major drainageways for carrying urban storm runoff. Sec. 17.56.020. - Statutory authorization.
