11.80.010 Purpose.

The purpose of the flood management overlay (FM) zone is to promote the public health, safety, and general welfare and to minimize public and private losses due to flood conditions in specific areas designated by the Federal Emergency Management Agency and the Federal Insurance Administration. The requirements of this chapter must be met in addition to those of the underlying zone district and regulations established in Chapter 12.08 RCC, Flood Damage Prevention. This district is intended to meet the requirements of the federal government in order to maintain the city’s eligibility for resident participation in the flood insurance program. (Ord. 2041 § 1 (Exh. A), 2010; Ord. 1024 § 11.02.161, 2001).

11.80.020 Location of overlay zone and establishment of boundaries.

The areas of special flood hazard are shown as an overlay district on the city’s official zoning map and are identified more specifically on the flood insurance rate maps and flood boundary-floodway maps. The flood hazard area includes land within the 100-year floodplain and the floodway. The floodway area includes the channel or other watercourse and adjacent land areas that must be reserved in order to discharge the base flood without cumulatively increasing the water surface elevation more than one foot. For areas of special flood hazard studied in detail, the floodway boundary is delineated upon the flood insurance study maps.

The areas of special flood hazard identified by the Federal Insurance Administration in a scientific and engineering report entitled “The Flood Insurance Study for the City of Ritzville” dated August 4, 1988, and any revisions thereto, with an accompanying flood insurance rate map (FIRM), and any revisions thereto, are hereby adopted by reference and declared to be a part of this title. The flood insurance study and the FIRM are on file at City Hall. (Ord. 2041 § 1 (Exh. A), 2010; Ord. 1024 § 11.02.162, 2001).

11.80.030 General standards.

All property located within the flood management overlay zone is subject to all of the use restrictions and development standards of the underlying zone as minimum standards unless otherwise specifically provided by this chapter or by an approved planned unit development. (Ord. 2041 § 1 (Exh. A), 2010; Ord. 1024 § 11.02.163, 2001).

11.80.040 Other applicable regulations.

In addition to the requirements contained in this chapter, the requirements contained in Division III, Supplementary Standards, shall also apply to development in the flood management overlay zone. (Ord. 2041 § 1 (Exh. A), 2010; Ord. 1024 § 11.02.164, 2001).

11.80.050 Application.

No structure or land shall hereafter be constructed, located, extended, converted, or altered without full compliance with the terms of this title and other applicable regulations. (Ord. 2041 § 1 (Exh. A), 2010; Ord. 1024 § 11.02.165, 2001).
