U INDIAN RIVER COUNTY, FLORIDA BOARD MEMORANDUM TO: Joseph A. Baird, County Administrator THROUGH: Christopher R. Mora, P.E. Public Works Director FROM: James D.Gray,Jr. �� Coastal Engineer O SUBJECT: Work Order No.3 Coastal Planning and Engineering, Inc. Indian River County Beach Preservation Plan—2014 Update DATE: September 30,2013 DESCRIPTION AND CONDITIONS On March 19, 2013 the Board approved a contract with Coastal Planning and Engineering, Inc. (CPE) for professional coastal engineering services in Indian River County for a two-year term, 2013-2015. CPE is the selected County consultant for professional engineering services related to updating the County Beach Preservation Plan(BPP) in the year 2014. Indian River County developed and adopted its first comprehensive BPP in 1988, which included a management strategy for addressing coastal erosion along the County's 22.4 miles of shoreline. The BPP has been subsequently updated in 1998 and 2008. Following the recently completed Sector 3 Beach and Dune Restoration Project, a public workshop was held to discuss and identify additional strategies to abate the erosional effects on the County shoreline other than the traditional methods of pumping or trucking sand to the beach. During the public workshop several recommended strategies were discussed including the use of coastal structures (breakwaters, groins, etc.). It was later determined that an update to the BPP was warranted and should include coastal modeling studies for the use of coastal structures. The proposed Work Order No. 3 provides professional engineering services required to update the County Beach Preservation Pian. The proposed 2014 BPP update includes: use of a three dimensional numerical model to determine countywide sediment transport rates and the effectiveness of coastal structures, storm damage vulnerability analysis on public and private infrastructure, presents recommended strategies to manage the shoreline, project costs for those strategies, and provides recommendations for appropriate federal, state, and local funding. Once completed, the updated BPP will provide staff and the public with a sound engineering approach to future management of the County's beaches. Staff discussed, received feedback, and revised the proposed Work Order No. 3 based on recommendations from the County's Beach and Shore Preservation Advisory Committee.
