INDIAN RIVER COUNTY MITIGATION REEF PROJECT TECHNICAL AND ENVIRONMENTAL SPECIFICATIONS by the COUNTY to construct the reef, as required , in a safe and environmentally sound manner. 18 . 17 Fiber Optic Cables . A cable avoidance buffer zone located north of the construction Mitigation Area has been established with the intent of prohibiting CONTRACTOR access in the area of all known AT&T fiber optic cables in the vicinity. The area is identified as Cable Avoidance Buffer Area on Sheets 1 , 2 and 4 of the Construction Plans . UNDER NO CIRCUMSTANCES shall the CONTRACTOR or Subcontractors work or anchor within the Cable Avoidance Buffer Area . Any damage done to fiber optic cables or any devices buried or unburied within this avoidance area by CONTRACTOR or Subcontractor equipment, materials or personnel shall be the sole responsibility of the CONTRACTOR . The COUNTY and the ENGINEER shall not be held liable in any way for damages to cables or devices within this area . All fines or fees incurred within or related to the Cable Avoidance Buffer Area shall be the sole responsibility of the CONTRACTOR . 17 . 17 Nearshore Exposed Hardbottom . In an effort to minimize the impacts to nearshore hardbottom , an area of known exposed hardbottom has been identified on Sheets 1 , 2 and 4 of the construction plans . The CONTRACTOR and all Subcontractors shall not work or anchor within these areas . Any applicable fines or fees resulting from CONTRACTOR activity within these areas shall be the sole responsibility of the contractor. Due to the ephemeral nature of the hardbottom in the area the CONTRACTOR must take care not to damage any recently exposed and/or Ephemeral Hardbottom not identified on the plans — this exposed and/or Ephemeral Hardbottom may be located anywhere within or adjacent to the Project Area . The CONTRACTOR shall be held responsible for damage done to the existing exposed and/or Ephemeral Hardbottom by the CONTRACTOR or Sub-contractors . 17 . 18 County Acceptance . Following reef construction , inspection and acceptance of the constructed Mitigation Area by the COUNTY, the CONTRACTOR shall remove any and all mooring lines and construction buoys . 18 . MATERIAL PLACEMENT The Contractor shall place individual material units consisting of limestone or coquina boulders of irregular shape as shown in the Plans . The total acreage of artificial reef is approximately 5 . 24 acres , which will simulate existing conditions of the reef areas that are being replaced by construction of the Mitigation Area . Reef material shall be placed such that 120-foot (length ) by 50-foot (width ) rectangles are constructed and such that the rectangles are oriented in the shore perpendicular position , as indicated in the Construction Plans . The spaces between each of the rectangles shall be 10 feet in width and 120 feet in length , also oriented in the shore perpendicular position . A total of 36 High Relief High Complexity rectangular units and 2 Low Relief Low Complexity rectangular units shall be constructed . Each individual material limestone or coquina boulder ( stone ) shall be placed with its long axis perpendicular to the shoreline for stability . Each individual material unit shall TS- 14
