Residential & Commercial Waterfront Developments

Coronado Cays Waterfront Development, San Diego, CA.

NCI provided planning and engineering design services for the marine aspects of this $100-million waterfront development, which included over five miles of reinforced concrete sheet pile bulkheading, riprap slope protection, floating breakwater protection, dredging, and marking of navigational channels. Work included the preparation of plans, specifications and construction cost estimates, along with onsite construction inspection.

Ventura Keys, Ventura, CA.

NCI provided all waterside engineering for the development of Ventura Keys, a residential waterfront community, which is located adjacent to and north of Ventura Harbor, and shares the Ventura Harbor entrance channel to the ocean. The residential waterfront channels and slope protection were excavated and constructed in the dry prior to final excavation of the earth plug separating the development from the ocean waters. Engineering planning and design services included excavation/dredging of the channels/side slopes; stone riprap slope protection; and floating docks, piling and gangways for the entire development. Construction support services were also provided during construction of this waterfront community.

Lake Elsinore Master Plan/Economic Feasibility Study, Lake Elsinore, CA.

Lake Elsinore has a water surface area of over 3,000 acres, and supports a diversity of water sports such as power boating, sailing, rowing, fishing, waterskiing, and swimming. Other recreational activities enjoyed at the lake include sunbathing, picnicking, walking, jogging, bicycling, and organized special events. NCI's objective for this Master Plan Study was to recommend new facilities and develop management strategies, lake water use capacities, and a lake water access plan that would maximize recreation and water sport activities on and around the lake. This included a projection of maximum boat counts, class mixes and space allocations; development of lake rules and regulations; and designation of special events, lake and shoreline use areas. In addition, a specific lake development plan was proposed with conceptual plans for marinas, boat launch facilities, beaches, resort complexes and a special events arena. Potential revenue generation, capital costs, operating and maintenance costs were developed for these facilities. Recommendations pertaining to implementation priorities, public and private participation, and concessionaire operations were also presented.

Mission Bay Park, Master Plan Update, San Diego, CA.

NCI prepared the water use element of the newly revised master plan for this popular 7-square-mile urban waterfront park. Existing facilities and amenities were inventoried to assess current recreation characteristics. Future needs and priorities were then projected into the next century for the unique and diverse mix of inland waterway and sea-going leisure pursuits that occur within the Park. Planning issues that were addressed in the study included water use space allocation, lease dedication, access to the water, safety, boat storage, water quality, and waterway and shoreline maintenance. Recommendations were made to balance the competing demands of high-speed boating, personal watercraft, paddle sports, sailing, windsurfing, and other forms of passive and active water oriented recreation. Technical support was provided in a series of meetings and workshops to solicit public comment and input to the Master Plan update.

Hansen Dam 15-Acre Recreational Lake, Los Angeles, CA.

The Corps of Engineers was directed to plan, design and construct a recreational lake and associated recreational facilities at Hansen Dam. To initiate the planning and design process, NCI prepared the Feature Design Memorandum that presented all engineering design criteria for final design and construction of a 2-acre swimming area for swimming, sunbathing and child's wading activities; a 13-acre recreational water area for non-powered boating, sailing and fishing uses; and associated recreational facilities for parking, turf/picnic areas, restrooms, lifeguard buildings and stands, launching ramp, footpath and service road. This included engineering criteria for all civil design, hydraulic design, landscape design, and design of associated recreational facilities. Design elements consisted of the lake's physical layout; lake liner and shoreline treatments; drainage features; and water quality control for the swimming area, filtration pond and recreational area. Water quality control consisted of chlorination, circulation/filtration, aeration and ozonation systems. A comprehensive construction cost estimate and operations/maintenance cost estimates were developed for this project using the Corps' M-CACES program.

Newport Coast Planned Community, Newport Coast, CA.

NCI's service consisted of a third party independent review of the hydrologic, sediment yield, and coastal processes issues, technical documents, results, and conclusions that were prepared by numerous consultants working for the Irvine Company (TIC) pertaining to their planned development of Newport Coast Phase IV-3 and IV-4 that were under Coastal Commission Appeal. Phase IV-3 and IV-4 consist of 1,062 acres extending from the inland side of Pacific Coast Highway fronted by Crystal Cove State Park to the ridge of the San Joaquin Hills Corridor, and falls within the Muddy Canyon/Los Trancos watersheds. The project consists of 635 residential homes, 32 acres of recreational development, 298 acres of dedicated open space lands, and the construction of commercial development and backbone infrastructure.

Our scope of services included the following tasks: 1) independent examination of the appropriateness of the modeling to the project site; 2) independent examination of hydrologic assumptions, input, modeling results and conclusions; 3) independent examination of assumptions, input and results of sediment yields, grain size and littoral area; 4) site visit with Commission staff and TIC personnel to facilitate review of hydrologic and hydraulic material; 5) independent assessment of the major causes of bank channel formation and the management program; 6) independent assessment of compliance with agreed-upon standards; recommendations for ways to improve or modify the project, either to reach compliance or reach compliance in the least environmentally damaging manner; and 7) attendance at Commission staff meetings and Commission hearings.

Dana Point Headlands Development and Conservation Plan, Dana Point, CA.

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.

Treasure Island Redevelopment Project, Laguna Beach, CA.

This project consisted of the redevelopment of an existing 30 acre mobile home park in south Laguna Beach, containing 268 mobile homes/trailers, to a destination resort community with a maximum of 268 residential units, a hotel with a maximum of 300 rooms, public recreation/coastal access, public landscape, infrastructure improvements and conservation of coastal resources. NCI prepared the coastal engineering assessment for the proposed Treasure Island Destination Resort Community near Goff Island in the City of Laguna Beach. 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 removal of deteriorated coastal structures, construction of new development on the bluff, and public beach access facilities were also addressed. Mitigation measures to minimize the identified potential impacts were analyzed.
