RASCO C�1r4f ` j RICHARD JA ' WEI , i i A ATTORNEY COASTAL COASTAL SYSTEMS INTERNATIONAL, INC. 464 South Dixie Highway • Coral Gables, Florida 33 146 Tel: 305/661-3655 • Fax: 305/661-1914 SYSTEMS 135040.01 INTERNATIONAL June 9, 1999 Mr. James DeCocq Assistant Village Manager VILLAGE OF KEY BISCAYNE 85 West McIntyre Street Key Biscayne, Florida 33149 RE: ENGINEERING, ENVIRONMENTAL AND PERMITTING SERVICES FOR THE BEACH RENOURISHMENT PROJECT AT KEY BISCAYNE, FLORIDA Dear Mr. DeCocq: This is to submit an addendum proposal for services relative to the proposed Key Biscayne Beach Nourishment project. Specifically, the following presents a detailed scope of work for additional services to be provided by Coastal Systems International, Inc. (Coastal Systems) for the Village of Key Biscayne (Village): PART VI - ADDITIONAL FIELD INVESTIGATIONS During the 1st Pre -Application Consultation held with the Florida Department of Environmental Protection (DEP), staff noted concerns of potential impacts to seagrasses with the proposed beach renourishment project. Specifically, DEP staff questioned how the total acres of seagrasses impacted during the 1987 COE beach nourishment project compares to the potential impacts of the proposed 1999 beach renourishment project. In summary, DEP staff requested that a thorough resource (seagrass) survey and environmental impact assessment be provided that evaluates the 1987 pre -construction conditions, post - construction equilibrium toe of fill, review potential recovery rates based on historical aerial photography, and evaluate the potential additional impacts, if any, that may occur in the proposed 1999 beach renourishment project. Subsequently, a 2nd Pre -Application Consultation meeting was held with the COE, DERM and DEP wherein they agreed that the above evaluations were required as well as providing video mapping of the eastern hardbottom ledge and alternative pipeline corridor locations. Coastal Systems has preliminarily located a total amount of 1 million cubic yards of material identified within the 1987 COE borrow site and the proposed expanded borrow areas. Therefore the following services were required to confirm the avoidance and/or minimization of seagrass impacts, confirm the location of the expanded borrow areas, and determine quality content of sediment: (i) Additional Resource Mapping and Evaluations: Coastal Systems performed transects along the 1987 PL lines within the proposed beach fill limits to identify species and densities of the nearshore resources. In addition, Coastal Systems mapped Coastal, Environmental, Civil Engineering and Management 135040.01 Mr. James DeCocq June 9, 1999 Page 2 the resources using DGPS within a 500 foot radius of the 1987 COE borrow site and expanded borrow areas to delineate a buffer zone from the selected dredging areas. Coastal Systems provided video mapping of the eastern hardbottom edge and the proposed alternative pipeline corridors. Coastal Systems will summarize these findings within the Environmental Assessment report. (ii) Expanded Bathymetric Survey: Additional bathymetric data was collected within the expanded borrow areas. This survey was required to compare actual depths with existing data and avoid potential complications and/or change orders from the dredging contractor during construction. (iii) Hydrographic Survey: Coastal Systems conducted a hydrographic survey at the established 1987 PL lines 10A, 12, 14, 18, 20, and 23. The survey extended from a baseline placed landward of the active beach system to 1,000 feet offshore, or to a depth of 10 feet. (iv) Jet Probes: Coastal Systems performed eighteen (18) additional jet probes within the expanded borrow area to determine the qualitative content and approximate sediment thickness. This analysis will assist in determining the expanded borrow area and the quantity of available beach quality material. (v) Sub -Bottom Profiling: Coastal Systems collected detailed sub -bottom survey data of the expanded borrow areas. The survey will be performed consistent with the previous scope of work. PART VII - FUNDING Coastal Systems will coordinate with the Village and the Florida Department of Environmental Protection - Bureau of Beaches and Coastal Systems (DEP) to obtain state -reimbursement funds for beach renourishment. Coastal Systems will continue to maintain regular communication with the DEP staff and provide guidance to the Village throughout the state's funding process. PART VIII - PERMITTING a. Permit Applications/Permit Sketches: Coastal Systems will prepare permit sketches and a Joint Coastal Permit application suitable for submittal to the DEP and COE toward securing environmental permits for the proposed beach renourishment project. Permit sketches will reflect sand fill placement both along the uplands as a dune and below mean high water for beach expansion. In addition, the permit sketches will reflect details of the proposed borrow area. Coastal Systems will utilize the conceptual design, as developed previously in preparing permit sketches. The Dade County sand search investigations will be utilized for identifying the optimum borrow area for this project. Coastal Systems will prepare all sketches on CAD based on survey files. Permit sketches will be prepared on 8 %2" x 14" sized paper suitable for submittal to the DEP. COASTAL SYSTEMS INTERNATIONAL, INC. • Coastal, Environmental, Civil Engineering and Management 13 5040.01 Mr. James DeCocq June 9, 1999 Page 3 Coastal Systems will also prepare and submit a DERM Class 1 permit application toward securing the required local approval for dredge and fill activities. Coastal Systems will provide the Village with a draft copy of the permit sketches and permit applications along with a spreadsheet of construction fill quantities. Coastal Systems will meet with the Village to review the permit sketches and receive comments. Upon completion of the Village's review, Coastal Systems will prepare and submit eight (8) original copies of signed and sealed permit sketches along with an executed Joint Coastal Permit and DERM Class 1 applications to the DEP, COE, and DERM to initiate the review process. b. Processing: Coastal Systems will maintain contact with the DEP, COE, and DERM to answer staff questions, clarify the proposed design elements, and expedite permit approval. Upon response from the regulatory agencies, Coastal Systems will confer with the Village as to questions, revisions or additional items that may be required by the DEP, COE and DERM. Coastal Systems will respond to the completeness summaries and utilize existing data or data acquired and developed under this contract. Coastal systems will represent the Village before the regulatory agencies toward securing a final Joint Coastal Permit and Class 1 approvals. In addition, Coastal Systems will secure the following additional approvals that will be required. Please note the following: (i) Coast Guard Approval: The regulatory agencies may request that lighted buoys be placed to mark the boundaries of the borrow site for confirmation of dredge positioning. In addition, no swim buoys may be required by the permitting agencies to delineate the pipeline corridor. Coastal Systems will submit permit applications and process the necessary Coast Guard approval. (ii) State Lands Title Determination/Easement: Coastal Systems will coordinate with DEP State Lands to obtain title determinations and easements for work proposed on State owned lands. Specifically, the title determination and easement is required for work proposed to fill sovereign submerged lands, and the dredging of the borrow site. PART IX - PRELIMINARY AND FINAL DESIGN a. Preliminary Design: Coastal Systems will prepare a preliminary design of the beach renourishment project based on the conceptual design drawing previously prepared by Coastal Systems and approved by the Village and regulatory agencies. Coastal Systems will meet with the Village to review the preliminary design and to identify any minor changes that the Village may require. Coastal Systems will then prepare final design drawings incorporating minor revisions (to preliminary drawings) identified by the Village. b. Final Design: The final design drawings will include details and technical specifications suitable for construction of the beach renourishment project. The design will also include COASTAL SYSTEMS INTERNATIONAL, INC. • Coastal, Environmental, Civil Engineering and Management 135040.01 Mr. James DeCocq June 9, 1999 Page 4 details of the selected offshore borrow site and detailed dredging specifications.
