5. Applicants floodproofing nonresidential buildings shall be notified that flood insurance premiums will be based on rates that are one foot below the floodproofed level (e.g. a building constructed to the base flood level will be rated as one foot below that level). (c) Manufactured Homes. All manufactured homes to be placed or substantially improved within Zones A1-30, AH, and AE shall be elevated on a permanent foundation such that the lowest floor of the manufactured home is at or above the base flood elevation and be securely anchored to an adequately anchored foundation system in accordance with the provisions of subsection (1)(a)2 of this section. (d) Floodways. Within areas of special flood hazard established in section 9.6706 are areas designated as floodways. Since a floodway is an extremely hazardous area due to the velocity of flood waters which carry debris, potential projectiles, and erosion potential, the following provisions apply: Prohibition on encroachments, including fill, new construction, substantial improvements, and other development unless certification by a registered professional engineer or architect is provided demonstrating that encroachments shall not result in any increase in flood levels during the occurrence of the base flood discharge; and 2. If the conditions of subparagraph 1. above are met, all new construction and substantial improvements shall comply with all other applicable flood hazard reduction provisions of this section. (e) Shallow Flooding Areas - With Depth Designations. Shallow flooding zones appear on Flood Insurance Rate Maps (FIRM), with depth designations, wherever such flooding occurs on sloping water surfaces such as alluvial fan flow, wave wash after the wave has broken, etc. In these areas, the following provisions apply: New construction and substantial improvements of residential structures within these zones shall have the lowest floor (including basement) elevated above the highest adjacent grade of the building site, to at least one foot above the depth number specified on the FIRM. Where appropriate, such structures shall be elevated above the crown of the nearest road, to at least one foot above the depth number specified in the FIRM. Where hazardous velocities are noted on the FIRM, consideration shall be given to mitigating the effects of these velocities through proper construction techniques and methods. 2016 PIDS Manual, Appendix B-4 B-4-9
