Permittee : Indian River County Beach Restoration Permit No : 0166929A01 -JC Page 10 of 17 Stationary lighting on the beach and all lighting on the dredge shall be minimized through reduction, shielding, lowering, and appropriate placement of lights to minimize illumination of the nesting beach and water. Shields must be affixed to the light housing and be large enough to block light from all lamps from being transmitted outside the construction area (Figure 1 ) . e . From March 1 through May 1 , staging areas for construction equipment shall be located off the beach. Nighttime storage of construction equipment not in use shall be off the beach to minimize disturbance to sea turtle nesting and hatching activities . All construction pipes that are placed on the beach shall be located as far landward as possible without compromising the integrity of the existing or reconstructed dune system. f. Immediately after completion of the fill placement event and prior to February 15 for 3 subsequent years if placed sand still remains on the beach, the beach shall be tilled as described below. During the 3 years following each fill placement event, the permittee may measure sand compaction in the area of restoration in accordance with a protocol agreed to by the FWC, the Department, the U. S . Fish & Wildlife Service, and the applicant to determine if tilling is necessary. At a minimum, the protocol provided under a and b below shall be followed. If required, the area shall be tilled to a depth of 36 inches. All tilling activity must be completed prior to March 1 . An annual summary of compaction surveys and the actions taken shall be submitted to the FWC . If the project is completed during the nesting season, tilling shall not occur in areas where nests have been left in place or relocated unless authorized by the U. S . Fish and Wildlife Service in an Incidental Take Statement. This condition shall be evaluated annually and may be modified if necessary to address sand compaction problems identified during the previous year. 1 . Compaction sampling stations shall be located at 500400t intervals along the project area. One station shall be at the seaward edge of the dune/bulkhead line (when material is placed in this area) and one station shall be midway between the dune line and the high water line (normal wrack line) . 2 . At each station, the cone penetrometer shall be pushed to a depth of 6, 12, and 18 inches three times (three replicates) . Material may be removed from the hole if necessary to ensure accurate readings of successive levels of sediment. The penetrometer may need to be reset between pushes, especially if sediment layering exists . Layers of highly compact material may lay over less compact layers . Replicates shall be located as close to each other as possible, without interacting with the previous hole and/or disturbed sediments . The three replicate compaction values for each depth shall be averaged to produce final values for each depth at each station. Reports shall include all 18 values for each transect line, and the final 6 averaged compaction values. 3 . If the average value for any depth exceeds 500 psi for any two or more adjacent stations , then that area shall be tilled prior to March 1 . If values exceeding
