Shore Protection Project (SPP), North Boca Raton Segment, Beach Renourishment 2019, Palm Beach County, Florida

DESCRIPTION OF WORK: Project work consists of the reconstruction of a portion of the federally authorized project to restore the project area to pre-storm conditions. The project will consist of the placement of beach quality material along 1.45 miles coastline as shown on the drawings. The design cross section of the project includes an upper flat berm, lower sloped berm, and foreshore berm. The upper flat berm ties into the existing back berm at elevation +7.5 feet NAVD and extends the berm crest at elevation of +7.5 feet North American Vertical Datum 1988 (NAVD) at the Construction Baseline (CBL) or specified distance from the CBL. The lower sloped berm ties into the berm crest at elevation 7.5 feet NAVD and slopes downward on a 1-foot vertical on 100-feet horizontal (1V:100H) to elevation +6.5 feet NAVD88. The foreshore berm meets sloped berm crest at elevation +6.5 feet NAVD and slopes down to existing grade on a 1V:15H slope. Half-a-foot tolerance above the required is provided for a fill tolerance. The Borrow source for the project is approximately ½ mile offshore and 3 miles north of the placement area. Access to and from the borrow area is limited thru designated ingress and egress areas shown on the plans due to extensive offshore hardbottoms. The borrow area has two dredging cuts: Western cut (Section 1) and Eastern Cut (Section 2) where dredging will commence at the eastern cut to 95% of the target depth volume shown on the drawings before proceeding to Western cut. Work also includes endangered species monitoring, screening for rock, vibration controls and monitoring, turtle trawler mobilization/demobilization, and relocation trawling. The dredge shall be load-line Coast Guard Certified.
