Samuel Kissinger Village Manager VILLAGE OF KEY BISCAYNE 85 West McIntyre Street Key Biscayne, Florida 33149 November 25, 1996 135010 RE: ENGINEERING SERVICES RELATIVE TO THE VILLAGE OF KEY BISCAYNE LONG-TERM BEACH RENOURISHMENT PROJECT, DADE 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. 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 ll - COASTAL ENGINEERING EVALUATION The 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 Key Biscayne. Reports prepared by the US Army Corps of Engineers (COE) and other studies describing the history and performance of beach nourishment project within the project vicinity will be reviewed. Available hydrographic survey data will also be compiled within Coastal Systems' computer database to facilitate volumetric comparisons along the project shoreline and vicinity. The compiled hydrographic survey database will later be transferred to the Village for their own use. b) Shoreline/Volumetric Changes and Regional Sediment Budget: Coastal Systems will calculate the historical shoreline and volumetric changes within the region using available hydrographic surveys. In addition, these available hydrographic surveys will be 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 the region will be evaluated. The historical rate of erosion or accretion along the project beach will be assessed. Coastal, Environmental, Civil, Engineering and Management AFT 135010 Mr. C. Samuel Kissinger November 25, 1996 Page 2 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 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 matertals to be considered include offshore borrow sites and upland sources. 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 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 COASTAL SYSTEMS INTERNATIONAL, INC. • Coastal, Environmental, Civil Engineering and Management 135010 Mr. C. Samuel Kissinger November 25, 1996 Page 3 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 beach management plan report will he prepared summarizing the findings and making recommendations for the optimum design of beach renourishment along the Village of Key Biscayne. 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. In addition, this 5 -year plan will also include evaluation of viable beach maintenance alternatives, the Village proposed dune landscaping and beach walk plan, as well as public education. Specifically, an optimum beach maintenance plan will be recommended and presented to the Village for approval and adoption. The Village proposed dune landscaping and beach walkway plan will be evaluated and incorporated into this beach management plan. Public education relative to the adopted beach maintenance plan will be addressed. 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. COASTAL SYSTEMS INTERNATIONAL, INC. • Coastal, Environmental, Civil Engineering and Management J. 135010 Mr. C. Samuel Kissinger November 25, 1996 Page 4 Expenses, report preparation and costs relative to travel and accommodations will be invoiced separately pursuant to the above -mentioned Rate Schedule. Invoices will be submitted by the 15th of each month for the previous month's work. Invoices are to be paid within 30 days of receipt of the invoice by the Village. Invoices not paid after 30 days and not in dispute will incur interest at a rate of 1.5 percent per month. We look forward to working with you towards developing a successful beach management plan for the Village of Key Biscayne.
