Amendment 0004_ADDITIONAL BORROW AREA COORDINATES 202660819.docx

This is an amendment document providing additional borrow area coordinates and specifications for the Sea Bright to Manasquan, New Jersey FY 26 Renourishment project. The amendment designates four new borrow areas (Areas 7 through 10) from which fill material will be extracted for the beach renourishment effort. Borrow Area 7 has a maximum allowable cut depth of 56 feet, Borrow Area 8 allows for 67 feet of excavation, Borrow Area 9 permits 54 feet of cutting, and Borrow Area 10 allows 65 feet of extraction depth. All coordinates are referenced to the US State Plane Coordinate System NAD 1983, New Jersey Mercator Zone 2900 using US Survey Feet, with elevations based on the North American Vertical Datum of 1988 (NAVD88).

The amendment also identifies five core sample locations with their precise coordinates for geotechnical analysis purposes. These cores (numbered 1983-10, 1988-80, 1988-74, 1988-71, and 1988-78) are positioned within or near the borrow areas to provide subsurface information for the contractors executing the beach fill placement work. This technical data supports the Department of the Army Corps of Engineers' coastal storm risk management project, which requires placement of approximately 595,000 cubic yards of beach fill in the base bid with optional quantities totaling up to 791,000 cubic yards across the communities of Sea Bright, Monmouth Beach, and Long Branch in Monmouth County, New Jersey.
