The preliminary investigation results, presented in the existing conditions section, revealed sensitive environmental elements that will need to be protected. In order to gain a better understanding of the environmental conditions of the area, the Marlin Team proposes to perform a more detailed environmental investigation immediately after the contract execution. This survey will contain more detail of the existing conditions within the project area. These investigations will include a benthic resources survey, including seagrasses (between April 1 and August 31), soil, and water quality surveys. A detailed report of the findings will be generated, and be accompanied by maps identifying environmentally sensitive areas. Based on the findings of the detailed site investigations, impact avoidance will be the team's primary environmental goal beginning with the design phase of the bridge and the boardwalk. Scientists will work hand in hand with the engineers during the design phase to avoid impacts where possible. Where avoidance can not be exercised scientists will work with the construction staging team members and the permitting agencies, in order to minimize any impacts during the construction phase. Subsequent mitigation for those unavoidable impacts will be initiated and appropriately executed as determined by the appropriate agencies. It is anticipated that impacts to mangroves can be mitigated on uplands within the Town Center Park boundaries. Preliminary consultations with the permitting agencies will be initiated by the Team after the detailed environmental reports have been generated. It is anticipated that these meetings will occur within four weeks of the contract execution. Close coordination with these agencies are expected to facilitate and expedite the permitting process. The South Florida Water Management District (SFWMD) and the Dade County Department of Environmental Resources Management (DERM) are the two primary agencies that will be contacted during the pre-application consultation period. Consulting agencies will include the Florida Fish and Wildlife Conservation Commission (FFWCC), the United States Army Corps of Engineers (USACE), the National Marine Fisheries Service (NMFS), and the Florida Department of Environmental Protection (FDEP). Potential impacts that need to be evaluated during the pre-application consultations and the permitting process overall are those to mangroves, seagrasses, threatened and endangered species, water quality, state sovereign submerged lands, and navigation. Given the nature of the project and the conditions surrounding the project area, it is anticipated that a Standard General Permit will be required from the SFWMD, a Department of the Army permit will be required from the USACE, and a Class I permit from DERM will also be required for this project. Subsequent meetings with and presentations to the permitting agencies are anticipated as a course of this project in order to expedite the permitting process. Permitting is anticipated to take one year. ~~~~,
