August 18, 2020 Professional Consulting Services City of Sunny Isles Beach RFQ No. 20-07-01 Page 10 numerical modeling, sea level rise projections, storm surge analysis, resilient design, damage assessment and economic vulnerability analysis to uplands uniquely qualifies our team to deliver this project. Coastal Systems’ extensive background in coastal and civil engineering plays a vital part in the planning and implementation of this scope. Coastal Systems’ understanding of the present and future King Tide elevations, stormwater modeling capabilities, and expertise in site/civil design provides our team the means to design and develop budgets for effective and innovative drainage systems; these systems can be adapted to the changes in site conditions associated with sea level rise and climate change. Federal Emergency Management Agency (FEMA) ServicesFederal Emergency Management Agency (FEMA) ServicesFederal Emergency Management Agency (FEMA) ServicesFederal Emergency Management Agency (FEMA) Services Coastal Systems has a strong local reputation with Federal Emergency Management Agency (FEMA) technical analysis and regulatory interpretations. Our specialized team utilizes historic, meteorologic, hydrologic, and hydraulic data to interpret floodplain management regulations and evaluate Special Flood Hazard Areas (SFHAs). FEMA engineers and cartographers delineate SFHAs on Flood Insurance Rate Maps (FIRMs). SFHAs are those areas subject to inundation by a flood that has a one percent or greater chance of being equaled or exceeded during any given year. Coastal Systems reviews the design goals of a project to provide information to the project developer or architect relative to acceptable project design alternatives. In addition, Coastal Systems provides services to obtain variances from local floodplain ordinances, letters of no obligation from FEMA, and processes revisions to the SFHAs, as necessary, to meet project objectives. The firm regularly processes Letters of Map Revisions (LOMR) that can significantly reduce flood insurance premiums. Coastal Systems' permitting and engineering team works closely with attorneys, developers, architects, local officials, FEMA representative consultants, and FEMA officials to determine the most efficient and cost-effective design alternative for projects located within SFHAs. In addition, the firm has extensive experience preparing site-specific analyses for Coastal A zones to aid planners and architects with site plans and design requirements for buildings. Coastal Systems employs a variety of numerical modeling applications to assist in the analysis and design of project improvements and alternatives. Two modeling applications employed specifically for FEMA interpretations are the Wave Height Analysis for Flood Insurance Studies (WHAFIS) model and the Wave Run-up Model, which determine the height of run-up landward of the still water line. Coastal Systems has successfully implemented both applications on numerous projects requiring FEMA compliance interpretation or variance. More complex state-of-the-art models are also utilized for site specific analyses.
