Isiminger & Stubbs Engineering, Inc. 649 U.S. Highway, Suite 9 North Palm Beach, FL 3348 Dear Mr. Stubbs: Pursuant to Chapter 6.8 F.S. and Chapter.4 of Ordinance 8 of the Code of Laws and Ordinances of Martin County, Martin County approves and issues this emergency permit for mechanical sand placement of beach compatible sand above Mean High Water to you as agent for: Sailfish Point Property Owners and Country Club (POCC) SE Sailfish Point Boulevard Stuart FL, 34996 Sailfish Point POCC has authorization from all upland property owners to act as their agent in this project. Authorization from the Sailfish Point POCC is included in Attachment A. The project can be generally described as the placement of beach compatible sand along the eroded shoreline from approximately 34 feet south of DEP reference monument R-37 to R-39. Additional details can be found in the attached project aerial exhibit (Attachment B). The project construction will be initiated as soon as possible after this permit s effective date and all work will be completed by February 8,. The maximum amount of fill authorized by this permit is, cy. This permit is being issued based on documentation of extreme and accelerated erosion within the project limits. The project will be constructed in a manner to minimize adverse impacts to the coastal system native vegetation, associated species and adjacent properties. As the placement of beach compatible sand is not considered rigid coastal armoring, the sand may be left in place with no further permitting required. TELEPHONE 77-88-4 WEB ADDRESS http://www.martin.fl.us All sand placed will come from the County approved Stewart Mining as stated in contract AR -48. Sailfish Point POCC will ensure that Inspectors will be present onsite while the project is underway, and will of 9 EngL79
visually inspect a representative sample of truckloads each day (minimum % of trucks daily) prior to placement to ensure consistency of the material. A survey documenting current beach conditions and locating MHW will be conducted by Sailfish Point POCC prior to placement. The location of MHW will be staked at ft. intervals along the entire project length. Rapidly changing conditions and potential major shifts in MHW will be taken into consideration as the project progresses. No rigid shoreline protection is authorized by this permit. Please submit project updates to the County on a weekly basis. These reports and any additional questions may be submitted via email at kfitzpat@martin.fl.us. Sincerely, Kathy FitzPatrick, P.E. Coastal Engineer of 9 EngL79

Mark A. Powell December, 4 Isiminger & Stubbs Engineering, Inc. 649 U.S. Highway, Suite 9 North Palm Beach, FL 3348 Re: Native Beach and Upland Source Soil Sample Results Sailfish Point Navigation Channel Dredge/Dune Fill Project Sailfish Point, Martin County, FL Dear Mr. Powell:. (EAI) was contracted by Isiminger & Stubbs Engineering, Inc. to process six (6) sediment samples that were collected on November, 4 and delivered to EAI s laboratory on November, 4. The Scope of Work included grain size analysis to determine mean grain size (mm), sorting value, silt content (%), and shell content (%). The samples were also analyzed for wet Munsell color and carbonate content (%). This report presents the results of those analyses. Results Mean grain size values ranged from.3 mm from Sample R-38 to.46 from Sample Stewart Mine. Sample R-36 had the lowest sorting value (.6) and Sample Stewart Mine had the highest (.). Silt content ranged from.% (Sample R-36) to.4% (Sample Stewart Mine). Only one sample, R-4, had any shell content (.%). Color values were either YR/ or YR6/. All samples were compliant with sediment compliance specifications set forth in the Sediment Quality Assurance and Quality Control Plan for the Sailfish Point Navigation Channel Maintenance Dredging/Dune Fill Project (FDEP JCP #7446-8-JC): silt content was less than %, shell content was less than %, and Munsell color value was or lighter. The results for R-36, R-37, R-38, R-39, and R-4 Construction Berm Samples and the Stewart Mine - Beach Stockpile Upland Source Sample were certified by our professional geologist on December, 4 (see attachment) and are fully compliant with professional standards..
