fe rhnICA) APprOSCIt Page 9 view (1' = 200 feet) and section view (.at 1000 foot spacing) drawings will be prepared for two alternate configurations at each of the five Project areas (Sector 1, 2, 3, 5 and 7). The cross-section drawings will indicate design templates, advance fill templates, adjusted post -nourishment equilibrium profile, equilibrium We of fill, locations of hardbottom and the borrow area location relative to the Project. Task 3.3 Develop Project Cost Estimates Probable costs of engineering design, permitting, construction, and past -Project performance monitoring will be tabulated and presented in the report. Mitigation of nearshore hardbottom resource impacts will be estimated and probable costs for this item will be presented, Potential issues that could result in delays in permit acquisition will be identified. A suggested timeline for completion of significant design, permitting, bidding and construction milestones will be included in the report. Construction costs will be estimated to including mobi lizationldemobil ization, unit costs of sand excavation, delivery distances, and placement quantities, and mitigation and phys callbiological monitoring, An evaluation of alternate construction sequencing of Projects will be performed to evaluate the potential to reduce overall Project costs. All such costs shall be based on the information attendant with the expected sand source locations, hardbottom mapping studies and resultant artificial reef acreage's required for Project mitigation and the FDEP's standard Project monitoring requirements. Cost estimates will be developed in June 1999 for purposes of County planning purposes and formulation of the County's financing plan to implement the BPP (cost estimate #1). It is anticipated that three revisions of the project cost estimate will be required. Study findings and Project design recommendations will be presented to staff, the public through workshops, the Beach Advisory Committee and the County Commission, Task 3.4 Beach restoration Destgn Memorandum Report The Beach Restoration Design Memorandum Report will provide the information needed to file and initiate the processing of the Project permits including developing design beachfill templates, environmental resource mapping and sand characterization in sufficient detail to support applications to the 'State and Federal agencies. This report will detail the following: * sand source investigation/geotechnical data and overlay mapping of features, analyses of composite sand characteristics for alternate borrow area configurations for each candidate sand source with borrow areas mapped, ♦ natural resource mapping, hardbottom area characterization and quadrats along the nearshore area (to a depth of -18 feet) contiguous to each sand placement area and nearshore zone fronting the adjacent beaches that extend 1,000 feet north and 3,000 feet south of Project beach nourishment areas, typical beach nourishment section view templates, unit fill quantities (cylft), design beachfill quantities for each Project area and identified sand source including overfill quantity estimates (if required) and development of cost estimates based on the recommended sand sources, t side scan maps and bathymetric maps for the identified candidate borrow areas, graphics and exhibits for the permit pre -application meeting with the county, state and federal agencies to submit the report for their review. Plan and cross section views of beachfill template overlays on existing beach profile data (with the results of the environmental resource mapping depicted as an AutoCADf+GIS layer -controlled feature) will show the proximity of fill to existing natural resources. If the character (relief, biodiversity and location relative to shore) of nearshore hardbottom resources indicates a perceived immediate (direct burial by beachfill) or secondary (longshore and cross -store redistribution of sand subsequent to fill placement) impact to the resource, the total sand coverage acreage (both vertical Qr� "V. d -W vP Vw"A Vi KC *,1 tit Na Mae Usti X""
