Attachment A - Scope of Services June 2007 Work Order 7 Indian River County Beach Sectors 1 & 2 (Ambersand) Mitigation Reef Monitoring (Year 2 ) INTRODUCTION The permit for Indian River County Sector 1 and 2 Beach Restoration (Permit No. 0166929-001 - JC) required construction of a nearshore artificial reef as mitigation for impacts to the expected burial of 3 .8 acres of nearshore hardbottom . Approximately 3.6 acres of impact was expected to high-relief reef habitat dominated by sabellariid worm , and 0 .2 acres of low-relief, algae- dominated reef were predicted to be impacted by the beach restoration project. Two types of mitigation reef were constructed as mitigation for the two habitat types: high relief, high complexity ( HRHC ) reef and low relief, low complexity (LRLC) reef. The high relief, high complexity reef was designed to have a vertical relief of 3 to 6 feet, and boulders were partially stacked to achieve this vertical relief. The low relief, low complexity reef was designed to mimic a vertical relief of 1 to 2 feet using a single layer of boulders. To meet the permit-required mitigation , 5. 24 acres of artificial reef were constructed . Of the 5 .24 acres, 4 . 96 acres is HRHC reef (36 120 ft. x 50 ft. units) and 0. 28 acres of LRLC reef (two 120 ft. x 50 ft. units) were constructed . In addition to the 5. 24 acres of permit-required mitigation reef, 1 . 65 acres of LRLC reef were constructed . A total of 6 .89 acres of reef will be monitored to evaluate its performance as replacement habitat for impacted benthic communities and fish populations . This Work Order will provide services to fulfill the permit-required monitoring condition of the issued permit (including permit modifications to date) and the FDEP-approved Addendum to the Mitigation Plan dated July 11 , 2006. Task 1 Year 2 Monitoring : Benthic and Fish Habitat Assessments Under this task, a sub-consultant, Coastal Eco-Group, Inc. (CEG), will perform a benthic assessment and fish counts. The benthic assessment will include six 20-meter digital video transects and in-situ quadrat analysis (3 quads per transect). The point count method will be utilized for fish counts , and will include 10 counts on HRHC sections, 10 counts on LRLW sections, and 10 counts in adjacent control areas . The County will provide boat and support services for 3 days of field work and sea turtle observations per survey protocol . Task 2 Mitigation Reef Extent CEG and ATM will perform a survey for the verification of artificial reef acreage and vertical relief. The survey will be conducted using GPS positioning and in-water measurements of vertical relief of the reefs perimeter. The comer points of the reef will be mapped and shore-parallel digital video transects will be conducted . ATM will provide FDEP data regarding the condition of the reef, the extent of the reef planform area , and vertical relief and pertinent issues regarding the project permit.
