Ob <br />40 <br />40 <br />Task 7 Final Review Meeting with County Staff and Corps of Engineers. The contractor will submit <br />the Draft Final Environmental Assessment to the County and Corps for review. The contractor will meet <br />with the County and Corps to discuss the document and incorporate any final comments. <br />Task 8 Prepare Final Environmental Assessment. The contractor will prepare the Final Environmental <br />Assessment and FONSI for use by the Corps to issue the Section 404 permit. One original, five hard <br />copies, and an electronic copy in Adobe Acrobat will be provided to the Corps for posting on their web <br />site. One original, 10 copies and an electronic copy will be provided to the county. <br />Task 9 Complete Marine Resource Mapping for Remainder of County. The contractor will complete <br />marine resource mapping for the remainder of the county utilizing the same ERDAS software and <br />imaging analysis technique used for existing maps. This analysis will include mapping of nearshore <br />hardbottom along the remainder of the county's shoreline (14 miles). Since no plans presently exist for <br />beach restoration along the additional 14 miles of shoreline the amount of ground-truthing of aerial <br />signatures required can be minimized. Hardground cover types previously classified will be used for these <br />additional areas. Due to limited time to complete the draft EA it is anticipated that draft maps will be <br />prepared for analysis prior to any field verification. Field verification will be scheduled from May -August <br />2001. To verify aerial signatures (cover types) no more than three transects per mile (total 42 transects) <br />will be surveyed during the summer using an Integrated Video Mapping System. Draft and final resource <br />maps will be provided to the county in hard copy and electronic format. A summary of acreages of marine <br />cover types found throughout the county will be prepared to assist in preparation of the cumulative impact <br />section of the EA. <br />Task 10 Prepare Cumulative Impact Assessment Report. The contractor will prepare a cumulative <br />impact assessment report which addresses the impact of beach restoration activities in the past, present <br />and foreseeable future on nearshore hardground habitat and associated biological communities; sea turtle <br />nesting area, activities and foraging habitat; and fisheries resources. This assessment will follow <br />methodology recommended by the Corps of Engineers and EPA and will include a trend analysis of <br />resource conditions and area from 1972 to 2010 (see attached outline). The trend analysis will include <br />delineating the nearshore limits of hardground from 1972 survey transects and graphically comparing <br />them to the 1999 survey limits. Assuming erosion has lead to increased acreage of hardground habitat <br />throughout most of the county, this analysis should indicate the location and actual area of changes in <br />hardground habitat to present time. Impacts from past activities would be determined from reviewing <br />Inlet Tax District records and permits for the beach fill template south of Sebastian Inlet. Any other <br />permitted activities would be assessed to determine whether they had any impact on marine resources. <br />The county will provide a breakdown of proposed direct impacts for all segments which may be <br />nourished by 2010, as well as a summary of other structural or non-structural shoreline protection projects <br />either constructed since 1972 or anticipated prior to 2010. <br />Projecting indirect impacts of the proposed project and other segments, if funded and constructed, would <br />require modeling of sediment spreading for segment I and 2 and using the results of this effort as an <br />assumption of likely indirect impacts for the other three segments. Temporal impacts due to <br />renourishment events would also be analyzed. The County's engineering consultant will develop the <br />sediment spreading model and provide the results of the analysis to the contractor for this assessment. <br />Analysis of trends in sea turtle nesting area will be completed by spatially analyzing the area of dry beach <br />available for nesting in 1972 and 1999. It is assumed the 1972 survey data compiled by the state will be <br />usable in determining the area of dry beach in 1972. Nesting data will be compiled from the county and <br />state agencies, summarized and correlated to observed changes in beach nesting area, false crawls and <br />other available information. <br />
