Original and Final Surveys:

The Contractor must make original and final surveys under the supervision of the Contracting Officer's representative and must make computations to determine the quantities of materials placed on the beach for acceptance.

Surveys for Progress Payments:

THE ENVIRONMENTAL WINDOW OF April 1 TO September 30)

b. Seabeach Amaranth

During each construction cycle, the Contractor will provide a qualified biologist(s) or botanist(s) to survey the work sites for the Federally threatened plant species, seabeach amaranth on a weekly basis to determine the presence of any plants. The Contractor shall take all reasonable precautions to ensure that his work is not conducted in a manner harmful to the seabeach amaranth. The Contractor's personnel shall be aware of the presence of such species and be sufficiently familiar with them so as to minimize contact with them during normal construction hours.

The fencing shall remain in place through the end of construction. The fence will consist of snow fencing at a height of three feet around a 10-foot diameter.

The biologist or botanists will determine the adequacy of fencing so erected and determine the need for additional protection. The zone within the fencing shall be OFF LIMITS to all personnel at all times. In the event, that the plants cannot be avoided due to their spatial distribution and/or abundance, the Contracting Officer will contact the USFWS and New York Department of Environmental Conservation (NYSDEC) to obtain the necessary permits to allow for plant transplantation to nearby suitable habitat (within the action area if possible) and seed collection (which would later be rebroadcasted)

In the event that Red Knot are observed within this period, prior to the start of work, or while work is being performed, the contractor shall maintain a 300-meter buffer surrounding the location of the Red Knot and notify the U.S. Fish & Wildlife Service (USFWS), Long Island Field Office (Region 5) at (631) 286- 0485 for further consultation and instructions. The surveys shall be conducted in the following manner:

(1) Inclement Weather: The Contractor shall not conduct surveys in weather with strong winds (>24 mph), heavy fog (<200 m visibility), or steady rain.

(2) Survey Protocol and Data Collection: The Contractor shall begin each survey of each area by indicating the start time. The Contractor shall count and identify Red Knot (and other species) in the survey area. This includes birds that enter or leave the survey area during the survey. For shorebirds to be considered "using" the survey area, the birds need to be on the ground within the defined survey area for at least part of the time it takes to do the survey. Shorebirds that fly over the survey area but do not land in it should NOT be counted. The USACE shall record numbers as the survey is continued. The Contractor shall complete surveys within the optimal 3-hour survey window around peak high tide. Once the area has been thoroughly searched and all birds seen have been recorded, the count is considered complete.

In SECTION 35 20 23, DREDGING, the following paragraph has been revised:

1.3 MATERIAL TO BE REMOVED

The material to be removed is more than 95% sand.

Under the Basic Work, maintenance dredging of approximately 750,000 cubic yards of sand which would be placed along 9,300 linear feet of Gilgo Beach shoreline, between baseline survey stations 93+00 and 00+00.

The Basic Work will require dredging to a plane of -14 feet mean lower low water plus 2 feet allowable overdepth.

All Optional Work will require dredging to a plane of -14 feet mean lower low water plus 2 feet allowable overdepth if exercised.

Grad Sample Requirements:

The contractor must obtain grab samples of the placed fill from: the beach backshore; edge of berm; mean high water (MHW); and mean low water (MLW). One set of samples must be taken every 200 feet along the placed fill area. A grain size analysis of each sand sample will be made using sieve sizes comparable to the Wentworth size classifications (shown in Section 00 90 04 WENTWORTH SCALE) and the results plotted on an appropriate curve format. The laboratory analysis results, and plotted grain size distribution curves must be furnished with the Daily

Construction Quality Reports.

The contractor must obtain a minimum of three (3) grab samples from the channel, three (3) from the eastern deposition basin, and three (3) from the ebb shoal area. Samples must be spaced throughout these areas, and locations must be provided along with grain size analysis. A grain size analysis of each sand sample will be made using sieve sizes comparable to the Wentworth size classifications (shown in Section 00 90 04 WENTWORTH SCALE) and the results plotted on an appropriate curve format. The laboratory analysis results, and plotted grain size distribution curves must be furnished with the Daily Construction Quality Reports.

NOTE: The Contractor is required to conduct a daily toolbox safety meet and include what was discuss on the daily report submitted to the U.S. Army Corps of Engineers.
