being transmitted outside the construction area, as illustrated below. 15. Equipment Storage. Staging areas for construction equipment for sand placement shall be located off the beach to the maximum extent practicable from May 1 to October 31. a. Nighttime storage of the beach restoration project construction equipment not in use shall be off the beach to minimize disturbance to sea turtle nesting and hatching activities. b. 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. i. Temporary storage of pipes shall be off the beach to the maximum extent possible. ii. Temporary storage of pipes on the beach shall be in such a manner so as to impact the least amount of nesting habitat and shall not compromise the integrity of the dune systems. Joint Coastal Permit Western Destin Beach Restoration Permit No. 0286575-001-JC Page 12 of 26 iii. Pipes placed parallel to the dune shall be five to ten feet away from the toe of the dune. 16. Fill Restrictions. During nesting season, the contractor shall not extend the beach fill more than 500 feet along the shoreline between dusk and the following day until the daily nesting survey has been completed and the beach cleared for fill advancement. a. If the 500 feet is not feasible for the project, an agreed upon distance shall be decided on during the preconstruction meeting. b. Once the beach has been cleared and the necessary nest relocations have been completed, the contractor is allowed to proceed with the placement of fill during daylight hours until dusk at which time the 500-foot length limitation shall apply. 17. Beach Maintenance. All derelict concrete, metal, and coastal armoring material and other debris shall be removed from the beach prior to any dredged material placement to the maximum extent practicable. If debris removal activities will take place from May 1 through September 1, the work shall be conducted during daylight hours only and shall not commence until completion of the sea turtle survey each day. All excavations and temporary alterations of the beach topography shall be filled or leveled to the natural beach profile prior to 9 p.m. each day. 18. Hopper Dredging Requirements. In the event a hopper dredge is utilized, the following requirements shall be met in addition to the Terms and Conditions of the NMFS Regional Biological Opinion for Hopper Dredging in the Gulf of Mexico: a. Handling of sea turtles captured during hopper dredging projects shall be conducted only by persons with prior experience and training in these activities and who is duly authorized to conduct such activities through a valid permit issued by the FWC, pursuant to Florida Administrative Code 68E-1. b. Dredging Pumps. Standard operating procedure shall be that dredging pumps shall be disengaged by the operator when the dragheads are not firmly on the bottom, to prevent impingement or entrainment of sea turtles within the water column. This precaution is especially important during the cleanup phase of dredging operations. c. Sea Turtle Deflecting Draghead. A state-of-the-art rigid deflector draghead must be used on all hopper dredges in all Gulf of Mexico channels at all times of the year. Joint Coastal Permit Western Destin Beach Restoration Permit No. 0286575-001-JC Page 13 of 26 d. The Sea Turtle Stranding and Salvage Network (STSSN) Coordinator, Dr. Allen Foley, shall be notified at (904) 573-3930 of the start-up and completion of hopper dredging operations. e. Relocation trawling shall be undertaken at all projects where any of the following conditions are met; however, other ongoing projects not meeting these conditions are not required to conduct relocation trawling: i. Two or more turtles are taken in a 24-hour period in the project ii. Four or more turtles are taken in the project. f. The Permittee shall fax (850-921-6988) or e-mail (Meghan.Koperski@MyFWC.com) weekly reports to the Imperiled Species Management Section on Friday each week that relocation trawling is conducted in Florida water. These faxes shall include: the species and number of turtles captured in Florida waters, general health, and release information. A summary of all turtles captured in Florida waters, including all measurements, the latitude and longitude (in decimal degrees) of captures and tow start-stop points, and times for the start-stop points of the tows, including those tows on which no turtles are captured shall be submitted to the ISM by January 15 of the following year. 19. Compaction Sampling. Immediately after completion of the beach restoration project and prior to April 15 for 3 subsequent years, sand compaction sampling shall be monitored in the area of sand placement in accordance with the following protocols: a. Compaction sampling stations shall be located at 500-foot 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). b. 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 lie 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. c. 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 April 15. Joint Coastal Permit Western Destin Beach Restoration Permit No. 0286575-001-JC Page 14 of 26 d. If values exceeding 500 psi are distributed throughout the project area but in no case do those values exist at two adjacent stations at the same depth, then consultation with the FWC shall be required to determine if tilling is required. If a few values exceeding 500 psi are present randomly within the project area, tilling shall not be required. 20. Tilling Requirements. Immediately after completion of the initial beach fill placement event, and prior to April 15 for 3 subsequent years, if placed sand still remains on the beach, the beach shall be tilled as described below or the Permittee may follow the procedure outlined below to request a waiver of the tilling requirement. During tilling, at a minimum, the protocol provided below shall be followed: a. The area shall be tilled to a depth of 36 inches. All tilling activity must be completed prior to April 15. Each pass of the tilling equipment shall be overlapped to allow more thorough and even tilling. Tilling should occur landward of the wrack line and avoid all vegetated areas 3 square feet or greater with a 3 foot buffer around the vegetated areas. b. An annual summary of compaction surveys and the actions taken shall be submitted to the FWC. c. If the project is completed just before the nesting season, tilling shall not occur in areas where nests have been left in place or relocated unless authorized by the USFWS in an Incidental Take Statement. d. This condition shall be evaluated annually and may be modified if necessary to address sand compaction problems identified during the previous year. e. To request a waiver of the tilling requirement, the Permittee may measure sand compaction in the area of restoration in accordance with a protocol agreed to by the FWC, the Department, the USFWS, and the Permittee to determine if tilling is necessary. 21. Escarpment Surveys. Visual surveys for escarpments along the beach fill area shall be made immediately after completion of the beach restoration project and between March 1 and April 15 for the following three years if placed sand still remains on the beach. All scarps shall be leveled or the beach profile shall be reconfigured to minimize scarp formation. In addition, weekly surveys of the project area shall be conducted during the two nesting seasons following completion of fill placement as follows: a. The number of escarpments and their location relative to DNR-DEP reference monuments shall be recorded during each weekly survey and reported relative to the length of the beach surveyed (e.g., 50% scarps). Notations on the height of Joint Coastal Permit Western Destin Beach Restoration Permit No. 0286575-001-JC Page 15 of 26 these escarpments shall be included (0 to 2 feet, 2 to 4 feet, and 4 feet or higher) as well as the maximum height of all escarpments. b. Escarpments that interfere with sea turtle nesting or that exceed 18 inches in height for a distance of 100 feet shall be leveled to the natural beach contour by April 15. Any escarpment removal shall be reported relative to R-monument. c. If weekly surveys during the marine turtle nesting season document subsequent reformation of escarpments that exceed 18 inches in height for a distance of 100 feet, the FWC shall be contacted immediately to determine the appropriate action to be taken. Upon written notification, the Permittee shall level escarpments in accordance with mechanical methods prescribed by the FWC. 22. Lighting Surveys. A survey of all artificial lighting visible from the project beach shall be conducted after the beach restoration project. The surveys shall document all lighting visible from the post-project restored beach. The post-project survey shall be conducted by May 15 following the project work and again by June 15, July 15, August 15, and September 15 of that nesting season. For each light source visible, it must be documented that the property owner(s) have been notified of the problem light with recommendations for correcting the light. Recommendations must be in accordance with the Florida Model Lighting Ordinance for Marine Turtle Protection, F.A.C. 62B-55. A summary report of each survey including documentation of property owner notification shall be submitted to the USFWS Panama City Florida field office by the 1st of the following month; and a final summary report provided by December 15 of that
