Szpyrka, P.E., Public Works Director THROUGH: Eric Charest, Natural Resources Manager SUBJECT: Work Order No. 16 - Morgan & Eklund, Inc. 2021 Beach Profile Monitoring Surveys (SUMMER) DATE: December 15, 2020 DESCRIPTION AND CONDITIONS On October 4, 2016, the Board of County Commissioners (BCC) approved a contract with Morgan and Eklund, Inc. (M&E) for Professional Land Surveying and Mapping Services for a two-year term. The Board amended the Contract on October 18, 2016. The contract was renewed for a two-year term on October 4, 2018, and then again on October 4, 2020 for an additional two-year term. M&E is the selected County Consultant for professional onshore/offshore hydrographic surveying services. The County's Beach Preservation Plan recommends semi-annual beach profile surveys in order to monitor the seasonal, summer and winter, fluctuations of the beach. Proposed Work Order No. 16 provides summer -time countywide hydrographic surveying (beach profile) services forthe Sectors 3, 5, and 7 Beach Nourishment Projects and additional surveying to begin a 2021 countywide monitoring effort. All onshore and offshore beach profile surveys are conducted along the Florida Department of Environmental Protection (FDEP) Range Monuments at approximately 1,000 foot intervals (alongshore) and extend from the vegetated dune seaward to a location approximately 40 feet offshore (cross -shore). Due to the anticipated Sector 7 Beach and Dune Restoration project construction anticipated to begin in November 2021, additional intermediate profiles lines are also being performed during this Summer 2021 survey. For project tracking purposes, Work Order No. 16 is divided into four (4) separate tasks. Task 1: Summer 2021 Sector 3, Phase 1 Phvsical Monitoring Survev (R-15 to R-45. 31 Onshore/Offshore Profile Lines) Hydrographic surveys of the project area must continue semi-annually to determine the long- term performance of the beach and if infrastructure may be vulnerable to storm damage during years in between recommended beach projects identified in the Beach Preservation Plan. Hydrographic survey data collected from this task is required for post construction monitoring for Phase 1 of the Sector 3 project. Task 1 includes surveying (approx. 5.9 miles) required to provide post construction physical monitoring data for Phase 1 of the Sector 3 Beach and Dune Nourishment Project area. The survey area is larger than the estimated 3.6 miles of beach being nourished due to monitoring requirements. Task 1 totals a lump sum amount of $18,142.50. 93
