or drilling operations or storage of equipment or materials. DFIRM database is a database, usually spreadsheets, containing data and analyses that accompany DFIRMs. The FEMA Mapping Specifications Guidelines outline requirements for the development and maintenance of DFIRM databases. Digital Flood Insurance Rate Map (DFIRM) is a FEMA digital floodplain map. These digital maps serve as "regulatory floodplain maps"for insurance and floodplain management purposes. Director means the director of planning of the city or the director's designee. Elevated building means a non-basement building built, in the case of a building in Zones Al- A30, AE, A, A99, AO, AH, B, C, X, and D, to have the top of the elevated floor above the ground level by means of pilings, columns (posts and piers), or shear walls parallel to the flow of the water and adequately anchored so as not to impair the structural integrity of the building during a flood up to the magnitude of the base flood. In the case of zones A I-A30, AE, A, A99, AO, AH, B, C, X, and D, "elevated building" also includes a building elevated by means of fill or solid foundation perimeter walls with openings sufficient to facilitate the unimpeded movement of flood waters. Encroachment lines are limits of obstruction to flood flows. These lines are generally parallel to the stream. The lines are established by assuming that the area landward (outside) of the encroachment lines may be ultimately developed in such a way that it will not be available to convey flood flows. The stream channel and adjoining floodplains between these lines will be maintained as open space and will be adequate to convey the 100-year flood without adversely increasing flood heights, such increase under any condition not exceeding one-half foot. Equal degree of encroachment is established by considering the effect of encroachments on the hydraulic efficiency of the floodplain along a significant reach of the stream, on both sides. Existing manufactured home park or subdivision means a manufactured home park for which the construction of facilities for servicing the lots on which the manufactured 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) are completed before the effective date of the ordinance from which this chapter is derived. Expansion to existing manufactured home park or subdivision means the preparation of additional sites by the construction of facilities for servicing the lots on which the manufactured homes are to be affixed (including the installation of utilities, the construction of streets, and either final site grading or the pouring of concrete pads). Flood or flooding means a general and temporary condition of partial or complete inundation of normally dry land areas from: a. The overflow of water from channels or reservoir spillways; b. The unusual and rapid accumulation or run-off of surface waters from any source; Ordinance No.1625,Series 2012 Page 4 of 31 4
