Ordinance Language Commentary the reach must be assumed in computing floodway boundaries. 6.24 The Zoning Administrator will review the submitted information and assess the technical evaluation and the recommended Floodway and/or Flood Fringe District boundary. The assessment must include the cumulative effects of previous floodway encroachments. The Zoning Administrator may seek technical assistance from a designated engineer or other expert person or agency, including the Department of Natural Resources. Based on this assessment, the Zoning Administrator may approve or deny the application. 6.25 Once the Floodway and Flood Fringe District boundaries have been determined, the Zoning Administrator must process the permit application consistent with the applicable provisions of Section 4.0 and 5.0 of this ordinance. SECTION 7.0 LAND DEVELOPMENT STANDARDS T1n General: Recognizing that flood prone areas may exist outside of the designated floodplain -districts, the requirements of this section apply to all land within (Community). 7.2 Subdivisions: No land may be subdivided which is unsuitable for reasons of flooding or inadequate drainage, water supply or sewage treatment facilities. Manufactured home parks and recreational vehicle parks or campgrounds are considered subdivisions under this ordinance. 7.21 All lots within the floodplain districts must be able to contain a building site outside of the Floodway District at or above the regulatory flood protection elevation. 7.22 All subdivisions must have road access both to the subdivision and to the individual building sites no lower than two feet below the regulatory flood protection elevation, unless a flood warning emergency plan for the safe evacuation of all vehicles and people during the regional (1% chance) flood has been approved by the (Governing Body). The plan must be prepared by a registered engineer or other qualified individual, and must demonstrate that adequate time and personnel exist to carry out the evacuation. 7.23 For all subdivisions in the floodplain, the Floodway and Flood Fringe District boundaries, the regulatory flood protection elevation and the required elevation of all access roads must be clearly labeled on all required subdivision drawings and platting documents. 7.24 In the General Floodplain District, applicants must provide the information required in Section 6.2 of this ordinance to determine the regional flood elevation, the Floodway and Flood Fringe District boundaries and the regulatory flood protection elevation for the subdivision site. 7.25 If a subdivision proposal or other proposed new development is in a flood prone area, any such proposal must be reviewed to assure that: (a) All such proposals are consistent with the need to minimize flood damage within the flood prone area, (b) All public utilities and facilities, such as sewer, gas, electrical, and July 2015 13 Federal rules require that communities assess the cumulative effects of floodway encroachments on both sides of a stream. Contact Floodplain Program staff for assistance in making this assessment. Section 7.1 is optional — this and related provisions in 7.25 and 7.3 are designed to enable communities to manage flood risks in unmapped but flood -prone areas (i.e., wetlands, ditches, isolated basins). If these standards are not needed, Section 7 can be retitled "Subdivisions." The subdivision requirements in Section 7.21 — 7.24 are mandatory. These provisions can be integrated into a city or county subdivision ordinance, where one exists. Note that manufactured home and recreational vehicle parks are treated as subdivisions. 7.25 is optional, to be used in conjunction with 7.1.
