AAPTIM August 1, 2019 Page 3 of 5 Pipeline Corridors: Once the sidescan sonar survey is complete and the data has been interpreted to identify hardbottom resources, the habitat within each proposed corridor will be verified in situ by divers. During each investigation, divers shall determine the presence or absence of hardbottom resources and, if present, note the general condition of the benthic community, identify dominant benthic organisms and substratum types, and estimate the vertical relief of the hardbottom. Video and/or photographs shall be taken to document the findings. Locations verified as areas with hardbottom resources shall be mapped in situ to document the current distribution of hardbottom resources within the pipeline corridors. Borrow Area: Once the sidescan sonar survey is complete and the data has been interpreted to identify hardbottom resources, the habitat will be verified in situ by divers. During each investigation, divers shall determine the presence or absence of hardbottom resources and, if present, note the general condition of the benthic community, identify dominant benthic organisms and substratum types, and estimate the vertical relief of the hardbottom. Video and/or photographs shall be taken to document the findings. Locations verified as areas with hardbottom resources shall be mapped in situ to document the current distribution of hardbottom resources within the pipeline corridors. Task 2 Deliverable FDEP requested a habitat characterization report to facilitate the Department's analysis of potential impacts to hardbottom resources. The report shall summarize the findings of the hardbottom reconnaissance survey described herein, which shall identify the location and distribution of hardbottom resources and describe the benthic resources observed on the hardbottom. The report shall describe the methods used during the reconnaissance surveys and data analysis, and will provide results of the survey in graphical, tabular and text formats. Raw data, video files and shapefiles from the reconnaissance survey will also be included in the report deliverable. Benthic biological data from previous monitoring efforts on the nearshore hardbottom adjacent to the project area will also be presented in the habitat characterization report. Task 2 Schedule The in situ diver verification of hardbottom resources will take place after the sidescan sonar survey has been completed and the data has been processed. Raw data from field operations will be submitted to the County and FDEP within 45 days and the monitoring report will be submitted within 90 days of completion of the survey. Task 2 Cost The lump sum cost for this task is $54,412.65. Summary The total lump sum cost to perform the proposed work described herein for Sector 3 — 2018006 — Work Order #6 is $96,629.15. Please refer to Exhibit 1, attached to the end of this proposal, for a summary of the costs and labor hours of each Task. APTIM will proceed with the tasks upon receipt of a signed work order from Indian River County (unless stated otherwise in the schedule). Thank you for the opportunity to serve Indian River County. We look forward to continuing to provide expert professional services to the County. Please do not hesitate to call if you have any questions.
