Preliminary engineering and design studies were performed by NCI to improve the existing Federal structure. A 100-foot rubble-mound spur was designed using hydraulic model test parameters to remedy localized beach erosion. The design included void sealing of the groin’s core to reduce upcoast sand leakage, and rebuilding of a portion of the groin’s mid-section to repair structural deficiencies. NCI prepared the detailed design plans and construction documents, supported the permit application process, and furnished on-site construction consultation.
