Samuel Kissinger Village Manager VILLAGE OF KEY BISCAYNE 85 West McIntyre Street Key Biscayne, Florida 33149 135010 RE: ENGINEERING SERVICES RELATIVE To THE VILLAGE OF KEY BISCAYNE LONG-TERM BEACH RENOURISHMENT PROJECT, DARE COUNTY, FLORIDA Dear Mr. Kissinger: This is to submit the proposal for coastal engineering services relative to the Village of Key Biscayne Long -Term Beach Renourishment project. This engineering service is to develop a 50 - year beach management plan that would outline the Village's needs for future beach renourishments and identify the procedures required to secure necessary permits, fundings and commitment of offshore sand sources from the regulatory agencies. The following are the proposed terms of agreement for engineering services to be provided by Coastal Systems International, Inc (Coastal Systems) for the Village of Key Biscayne (Village)• PART I - COASTAL ENGINEERING EVALUATION Pic following coastal engineering evaluations will be conducted to determine the Village beach performance subsequent to the 1987 beach nourishment project, understand the littoral processes within the project region, and develop a conceptual beach design plan. The specific components of this engineering evaluation are described in the following: a) Data Collection: Coastal Systems will collect and review available data relating to shoreline changes along the island of Key Biscayne (Key Biscayne). Reports prepared by the US Army Corps of Engineers (COE) and other studies describing the history and performance of beach nourishment projects within the project area will be reviewed. All available hydrographic survey data will also be compiled within Coastal Systems' computer database, in the format of range and elevation for each beach profile, to facilitate volumetric change comparisons along the project shoreline and vicinity. The compiled hydrographic survey database will later be transferred to the Village for their own use. h) Shoreline/Volurnetric Changes and Regional Sediment Budget: Coastal Systems will calculate the historical shoreline and volumetric changes within Key Biscayne using available hydrographic surveys. In addition, these available hydrographic surveys will be Coastal, Environmental, Civil, Engineering and Management aJd r7- Cd- ✓ I V -T - JV'` 1. -NJ 135010 Mr. C. Samuel Kissinger January 28, 1997 Page 2 compared to the original project design as outlined in the COE's General Design Memorandum and as built during the 1987 beach nourishment project The performance of the beach nourishment project constructed within Key Biscayne will be evaluated. The historical rate of erosion or accretion along the Key Biscayne beach will be assessed. This evaluation of historical shoreline and volumetric changes may be utilized to identify "hot spots" along the project shoreline, where exceptional erosion rates are noted. In addition, these evaluations will assist in understanding littoral processes within the project area and in developing the conceptual beach design plan. A sediment budget will be developed for the region, describing sand movement within specific segments established from Crandon Park south to Bill Baggs State Park. The net longshore sediment transport rate within the active littoral system, extending offshore to the depth of closure, within each of the established segments will be confirmed. c) Conceptual Beach Design: Coastal Systems will review the design plan developed in 1987 by the U.S. Army Corps of Engineers. Coastal Systems will develop a conceptual beach design for renourishing the entire beach along the Village based on the historic erosion rate within the area. This beach design plan will identify the extent of beach fill along the Village shoreline and design beach cross section with specified berm elevation and beach slope. The development of the conceptual plan will also take into consideration of the extent of the nearshore seagrasses, which will be delineated by DERM. Coastal Systems will calculate the quantity of sands required for the beach renourishment project and identify the frequency of the beach renourishment project within a 50 year time frame. The costs associated with implementation of the plan using various sand sources will be calculated. PART II - SAND SOURCE ASSESSMENT Coastal Systems will coordinate with DERM and COE to evaluate the available sources of sand fill suitable for the beach renourishment. Coastal Systems will review available geotechnical data towards assessing the quality and compatibility of these various beach fill materials. The expected performance and estimated cost of the various sand fill materials will be compared. The sand fill materials to be considered include offshore borrow sites, upland sources and Turks and Caicos sand. The methods of construction and associated costs of using various sand fill materials will be analyzed. PART III - FUNDING PROCESSES Coastal Systems will explore the funding availability from the U.S. Army Corps of Engineers, the State of Florida and Dade County for implementation of this long-term beach renourishment COASTAL SYSTEMS INTERNATIONAL, INC. • Coastal, Environmental, Civil Engineering and Management JdT I -LO-7/ VY . JV f" I u'.c 135010 Mr. C. Samuel Kissinger January 28, 1997 Page 3 project. Based on the above identified plan, Coastal Systems will coordinate with DERM (Dade County) to explore the feasibility of Federal participation for the project under the provisions of Section 103. Coastal Systems will also evaluate the present state funding status and coordinate with DERM to include this project in the Dade County funding application to the State. The processes and time required for obtaining the Federal, State and/or County fundings will be presented. The deadlines for funding applications for various regulatory agencies will be identified and incorporated into the 5 -year beach management plan schedule. The amount of funding available from various agencies will also be presented. PART IV - BEACH MANAGEMENT PLAN A preliminary beach management plan report will be prepared summarizing the findings and making recommendations for the optimum design of beach renourishment along the Village of Key Biscayne. This beach management plan will be submitted to the Federal, State and County to express the Village's needs for beach renourishment project and request the Federal acceptable offshore sand sources and funding support. Specifically, this report will include detailed descriptions of coastal processes, sand source and funding evaluations and beach management plan. Potential sand sources will be identified and available funding sources at Federal, State and local levels will be explored. A 50 -year beach management plan will be developed, outlining quantity of sands needed for the Village over a 50 -year time span as well as identifying the most cost effective sand source to meet the needs. An immediate 5 -year detailed plan will also be included in the report. This plan will specify the details of the plan elements and sequential occurrence of each plan element towards implementing the first beach renourishment project within 5 years. Upon completion, Coastal Systems will make a presentation to the Village Council regarding engineering findings and the 50 -year Beach Management Plan. PART V - CLIENT DIRECTED MEETINGS The phases of services provides for all local meetings with the Village, DERM and other professionals. Specifically, Coastal Systems will attend meetings with the Village, DERM, and/or other professionals, as required by the Village, to discuss permitting and funding strategy and/or progress and review the beach management plan. Coastal Systems may also meet with the Village and/or regulatory agency staff on site to observe project status. GENERAL Fees: Coastal Systems will invoice the Village for Parts I through IV services on a percentage complete basis for the fees identified herein. Fees for Part V services will be invoiced on an hourly basis pursuant to the Rate Schedule identified in our current agreement with Dade County. Expenses, report preparation and costs relative to travel and accommodations will be invoiced separately pursuant to the above -mentioned Rate Schedule.
