Indian River County Work Order Number 2018007-1 Sector 7 Beach and Dune Restoration Project Exhibit 1 - Scope of Work Task 3 — Prequalification of Upland Sand Sources FDEP is expected to require identification of details regarding the potential upland sand sources for FDEP assessment prior to FDEP issuance of a permit for Project construction. In general, CONSULTANT will assist the COUNTY with a solicitation to prequalify acceptable and potential upland sand sources to be identified in the permit applications. CONSULTANT will develop minimum "Geotechnical Standards" for beach fill based upon the Geotechnical Standards & Requirements included in the COUNTY's initial Sector 3 Project — updated to reflect: • existing governing statutes (161 F.S.) and rules (6213-33 & 6213-41 F.A.C.), • the results of the pre -application meeting held with FDEP under Task 1, • the expected equilibrated profile of sand fill and associated impacts upon hardbottom, • compatibility with native beach material characteristics based upon: mean grain size, percent fines, sorting, percent carbonate, and Munsell color (wet/dry). CONSULTANT will develop "Geotechnical Requirements" for documentation of potential upland sand sources — to be provided by potential upland sand suppliers; such requirements are expected to include: • documentation of compliance with the updated Geotechnical Standards, • representative samples of the sand fill proposed to be provided, and • as available: o a topographic survey of the upland sand source site; c a sufficient number of core borings to define the sub -surface stratigraphy; o sediment characteristics for each in-situ sediment layer including: (a) grain size distribution, (b) percent carbonate, (c) percent silt, and (d) Munsell color (wet/dry); o sediment characteristics of proposed processed sand material with a description of the processing methods; o an assay of the above - signed and sealed by a Professional Geologist or Engineer; the quantity of sand available and capacity of the mine to produce suitable sand, and additional information as may be requested by FDEP at the pre -application meeting. The COUNTY will prepare a Draft Solicitation for prospective suppliers to provide sand for nourishment of COUNTY beaches; the Draft Solicitation shall include COUNTY requirements associated with operation of a sand -mine and/or sand -hauling within County limits, including the Geotechnical Standards and Geotechnical Requirements described above. The COUNTY will provide the Draft Solicitation to CONSULTANT and meet with CONSULTANT to review and finalize the Solicitation; the COUNTY will incorporate revisions as warranted. The COUNTY shall publish the Solicitation, address questions of prospective suppliers, and receive responses from potential suppliers. The COUNTY shall provide copies of all responses to CONSULTANT, who will assess the proposed sand sources, and recommend sand source suppliers to be pre -qualified for use in construction of the Project. The COUNTY will notify the prospective sand source suppliers of the Solicitation results. CONSULTANT will prepare a written summary of the above as an Appendix for the Task 5 - Preliminary Design Document. Page 2 of 5 February 9, 2018
