1301.05 1301.05 f. The provisions of Section 1301.05, subdivision 5 (below) of this Chapter also shall apply. Subd. 5. Standards for All Flood Fringe Uses: a. All new principal structures in the flood fringe district must have vehicular access at or above an elevation not more than two (2) feet below the regulatory flood protection elevation. If the City approves a variance from this requirement, the City must specify limitations on the period of use or occupancy of the structure for times of flooding. In order to approve a variance from this requirement, the City must determine that adequate flood warning time and local flood emergency response procedures exist. b. Commercial Uses: Accessory commercial land uses, such as yards, railroad tracks, and parking lots (if allowed by the underlying City zoning designation) may be at elevations lower than the regulatory flood protection elevation. However, the City shall not approve a permit for such facilities for use by employees or by the general public in the absence of a flood warning system. Such a flood warning system shall provide adequate time for evacuation if the area would be inundated to a depth and velocity such that when multiplying the depth (in feet) times velocity (in feet per second) the product number exceeds four (4) upon occurrence of the regional flood. C. Manufacturing and Industrial Uses: Owners and operators of manufacturing and industrial uses shall take measures to minimize the interference of normal plant operations from flooding, especially those sites along streams or creeks that have protracted flood durations. Certain accessory land uses such as yards and parking lots may be at lower elevations subject to requirements set out in Section 1301.05, subdivision 5 b above. In considering development or permit applications for manufacturing or industrial uses, the City shall give due consideration to the needs of an industry whose business requires that it be located in flood plain areas. d. Contractors shall properly compact fill and properly protect the slopes by using riprap, vegetative cover or other acceptable methods. The Federal Emergency Management Agency (FEMA) has established criteria for removing the special flood hazard area designation for structures properly elevated on fill above the 100-year flood elevation. FEMA's requirements incorporate specific fill compaction and side slope protection standards for multi -structure or multi -lot developments. The owner or contractor should investigate these standards before starting the site preparation if requesting a change of special flood hazard area designation. e. Flood plain developments shall not adversely affect the hydraulic capacity of the channel and adjoining flood plain of any tributary watercourse or drainage system where the City has not specified a floodway or other encroachment limit on the Official Zoning Map.
