TO: The Honorable Members of the Board of County Commissionersn L FROM: Robert M. Keating, AICP 4N Community Development Director William G. Collins County Attorney James Davis, P.E. Public Works Director' DATE: April 14, 1989 SUBJECT: FLOOD INSURANCE AMENDMENTS TO THE STORMWATER MANAGEMENT ORDINANCE It is recommended that the data herein presented be given formal consideration by the Board of County Commissioners at their regular meeting of May 2, 1989. DESCRIPTION & CONDITIONS Recently, the Federal Emergency Management Agency (FEMA) complet- ed a reevaluation of flood hazards for Indian River County. The - Flood Insurance Rate Map (FIRM) resulting from this study was presented to the county last summer, and since that time the FIRM has been reviewed and has undergone a mandatory ninety day appeal period. Since no appeals were filed to the FIRM, it will become effective on May 4, 1989. FEMA requirements mandate that the county, in conjunction with adoption of the new maps, update its flood regulations to incor- porate new FEMA requirements. Because the county's flood regula- tions are part of the stormwater management ordinance, it is necessary to amend that section of the code. The proposed amendments are attached to this agenda item. ALTERNATIVES & ANALYSIS To maintain its eligibility for the National Flood Insurance Program, the county must adopt the applicable FEMA regulations. Essentially, the county's only other alternative is to adopt regulations which exceed FEMA's requirements. Failure to adopt such regulations will result in"the county's termination from the flood insurance program. As presently structured, the stormwater management ordinance meets most of FEMA's requirements. The proposed amendments attached to this item incorporate the new FEMA requirements into the stormwater management ordinance. Adoption of these amend- ments will ensure continued eligibility of the county in the National Flood Insurance Program (NFIP). One minor problem has arisen in scheduling the public hearing for the proposed amendment. Because of Confederate Memorial Day, a recognized legal holiday in Florida, the legal notice was adver- tised one day less than required for a regular public hearing. To resolve this problem and still take action within the neces- sary - timeframe, it will be necessary for the Board of County Commissioners to adopt the proposed amendments as an emergency ordinance. To do so, the board must waive the notice require- ments by a four-fifths vote, declare that an emergency exists, MAY 1989 27 �coK �� F,�uL 754
