JAS 27 1987 BOOK 67 u U E 135 IV. Additional Requirements for Manufactured Housing Located in Floodprone Areas The former FEMA regulations stated that mobile homes must be anchored, blocked and tied down when located in floodprone areas. The new regulations provide that all such housing to be placed in floodprone areas be elevated on permanent foundations at or above the base flood ele- vation. V. Criteria for Construction of Structures Within Coastal High Hazard Zones (V -Zones) The revised FEMA regulations mandate that all new construction and substantial improvements located in V zones be elevated so that the bottom of the lowest hori- zontal structural member of the lowest floor is elevated to or above the base flood elevation. Previously, measur- ing from the top of the member was.sufficient to meet FEMA regulations. In addition, wind and wave loading require- ments are included within the new regulations. VI Removal of the Additional One Foot Requirement The revised ordinance omits the additional County one foot elevation requirement. Although FEMA states that its base flood elevation levels are minimum safety measures and encourages local governments to maintain more strin- gent floodproofing standards, the additional one foot requirement has generally not been well received by the public. The most frequent complaints regarding this requirement are: 1) the additional cost of fill material; 2) placement of homes at the additional height makes them aesthetically unpleasing; 3) the additional height creates drainage problems for adjacent properties.. Based upon these complaints and the fact that the additional one foot requirement is not mandatory under FEMA, staff recom- mends that this provision be deleted. RECOMMENDATIONS Staff recommends that the Board of County Commissioners adopt the proposed ordinance. Robert Keating, Director of Planning & Development, noted that there are two items that are included in the proposed amendment to the stormwater management and flood protection ordinance that go beyond the scope of the flood insurance regulations: 1) Changing how the county addresses unnumbered A zones. Basically, A zones are areas within the 100 -yeas flood elevation and unnumbered A zone areas are where an engineering study has not determined what the minimum flood elevation should be. In 75 M
