ApPROACH AND METHODOLOGY <br />Coastal Systems' professional license is enclosed on the following page. <br /> <br />) <br /> <br />Coastal Systems is accustomed <br />to providing technical depth <br />and manpower to address <br />these issues on a timely basis <br />to keep the permitting process <br />moving forward as <br />environmental permitting is <br />most always on the critical <br />path of the project schedule. <br /> <br />The Coastal Systems team will utilize project management and <br />delivery methods for the City of Sunny Isles Beach that has <br />been successful with other local municipalities over the years. <br /> <br />These strategies have included the following: <br /> <br />. Define appropriate scope of services and project <br />implementation plan with schedule. <br />. Conduct Project Kick-off meeting to ensure the City's <br />requirements are identified in the early stages of the project. <br />. Begin the environmental permit application process as quickly <br />as possible to begin the time clock on permitting. <br />. Conduct topographic, boundary and underground utility survey <br />to prepare detailed base map for engineering design. <br />. The South Florida Water Management District (SFWMD) is <br />the state agency with jurisdiction over most stormwater <br />management projects. PERA may have delegated authority. <br />. Maintain open communication with regular updates to the <br />City on the permit processing. <br />. Involve the City in all agency negotiations throughout the <br />permit process to ensure that City staff hears the agency <br />concerns first-hand. <br />. Prepare comprehensive responses to agency Requests for <br />Additional Information (RAI). <br />. Begin Design Development and Construction Documents as <br />the permitting are being confirmed through the process. <br />. Drainage System Design - Once the site conditions are <br />understood, then the proposed improvements need be overlaid <br />onto the existing conditions so the grading and drainage can be <br />designed. Modern civil engineering tools such as Civil3D can <br />be utilized to provide cut/fill, roadway alignment and cross <br />sections for earthworks calculations. The drainage design <br />needs to be completed in accordance with engineering industry <br />practice and environmental regulatory requirements. Standard <br />runoff curves and rainfall intensity curves are utilized to <br />estimate runoff under the existing conditions scenario along <br />with the proposed site plan. The South Florida area is typically <br />flat and at lower elevations, therefore the design of the <br />conveyance system has to be completed carefully with <br />appropriate piping and structures to ensure proper drainage <br />flow. Normally a combination of drainage systems are utilized <br />that may include drainage wells, outfalls, retention ponds, <br />exfiltration trenches, or swales. The design can fmther <br />optimized to reduce construction costs. <br /> <br />Corporate Offic", 464 South Dixie Highway. Coral Gables, Florida 33146. Tel: 305-661.3655.
