Davis, P.E., Public Works Director' � ` AND , Christopher J. Kafer, Jr., P.E., County Enginee FROM: David B. Cox, P.E., Civil Engineer CL6-- SUBJECT: Request for Floodplain Cut and Fill Balance Waiver for Residence at 11230 Indian River Drive, I.D. No. 08-31-39-00000-0020-00003.0 REFERENCE: Project No. 99110162 DATE: January 6, 2000 DESCRTPTTON AND CONDITIONS Ameron Homes, Inc. has submitted a building permit application for a single family residence on the subject property, and has requested a waiver of the cut and fill balance requirement of Section 930.07(2)(d) of the Stormwater Management and Flood Protection Ordinance. The site is located in special flood hazard area Zone AE with base flood elevation of 9.0 feet N.G. V.D. The ten year flood elevation is 4.4 feet N.G.V.D. The proposed displacement of the floodplain below 4.4 feet for which the waiver is requested is 889 cubic yards as indicated in the attached letter from the applicant's engineer dated December 15, 1999. The project meets the cut and fill balance waiver criteria provided in Section 930.07(2)(d)I of being situated in an estuarine environment within the 100 year floodplain along the Indian River and in staff's opinion it appears that all other Stormwater Management and Flood Protection Ordinance requirements can be met without adverse impact on other lands in the estuarine environment. The applicant has also submitted an alternative grading plan that satisfied the cut and fill balance requirement without needing the waiver. The applicant is requesting the waiver so he will not be required to construct an on site retention area if the waiver is granted. JANUARY 18, 2000 -17- BOOK FAU
