This project consists of the development of 121 acres on the Dana Point Headlands in Dana Point to include 125 residential lots, a 65-room inn, up to 40,000 square feet of visitor/recreational commercial use, and 62 acres of public open space including 30 acres of conservation area. NCI prepared the coastal engineering assessment for the proposed Headlands Development and Conservation Plan. A baseline description of the local and regional coastal processes was prepared and compared to potential project impacts related to surf zone wave characteristics, cross-shore and alongshore sediment transport, and bluff erosion rates. Impacts associated with reconstruction of the existing revetment structure, reduction of sediment yield, construction of new storm drain outlets, pedestrian walkway and access ramp were also addressed. Mitigation measures to minimize the identified potential impacts were analyzed.

During a second phase of work NCI performed structural engineering design services for the design and preparation of construction drawings for the lot, improved retaining walls, rock revetment removal/replacement, and pedestrian walkways. In addition, NCI is performing quarterly beach transit surveys in order to monitor the ongoing health of the fronting beach.
