Initially NCI's services included review of the wave climate within the outer harbor and existing mooring facility, definition of safe zone(s) within the mooring area during a 50-year and 100-year storm event, and determination of potential anchorage hazard zone(s) on an annual risk exposure basis. NCI then designed, and prepared the plans and specifications for a new mooring basin including the mooring spacing, anchor weights, and chain and line sizes.

Alviso Marina County Park, Alviso, CA.

The Alviso Marina County Park Improvement Project included two phases. Phase I involved the concept planning, evaluation of alternatives, cost estimating, feasibility analysis, and master plan development for the Alviso Marina. The facility had shoaled in, had become overgrown with marsh vegetation, and was no longer usable as a recreational marina. Alternatives included re-establishing the marina through various structural alternatives, or abandoning the marina and creating a wildlife viewing area. The latter approach was the preferred alternative. Phase 2, currently in progress, involves the design, preparation of contract documents, and construction observation. Noble Consultants was responsible for the design of an ADA-compliant boardwalk that crosses the marina through the wetlands, and design of the observation overlook. This included the evaluation of construction materials, design layout, and construction methodology to minimize impacts on the vegetation and sensitive wildlife.

National City Marina, National City, CA.

This project to construct a new 250-slip municipal marina facility involved the excavation and removal of 638,000 cubic yards of sand and underlying weak saturated soils to create a new mooring basin within existing tidelands. NCI prepared the final design of the mooring basin, which included supervision of necessary geotechnical studies to determine the soil's engineering properties; computation of cut-and-fill material quantities; identification of alternative spoil disposal plans; and description of construction methods to excavate the rectangular basin. The Basis of Design analysis also included the hydraulics related to the adjacent Sweetwater Channel, tidal influence from San Diego Bay, and potential sedimentation within the marina's entrance area. To improve the basin flushing capability during ebb tides, a set of culverts were designed within the existing rock revetment separating Sweetwater Channel from the marina basin. In addition, the marina's entrance was designed by removing and reconfiguring a section of the existing Sweetwater Channel slope revetment. NCI prepared a marina layout plan for the 250 boat marina, and prepared plans for the parking, entrance road, security fencing and other landside improvements. NCI also provided engineering construction support and evaluation to the Port of San Diego during the construction excavation and completion of the marina basin's entrance.

Proposed Marina Plan for Redevelopment of Burton Chace Park, Marina del Rey, CA

During late 2008 and 2009/2010 NCI prepared a master conceptual plan to replace all existing floating dock marinas for Parcels 45, 47, EE, 48 and 77, and to add an additional boarding float at the existing public boat launch facility for Parcel 49R at the Burton Chace Park Peninsula in Marina del Rey. This master plan was performed due to both the deteriorating condition of the existing marinas and to better utilize the water side space for the berthing of boats. For Parcel EE on the main channel side this proposed plan also included the addition of a fixed pier structure on the northern end and a fixed pier structure on the southern end that is fronted by a 120 foot long floating dock for use as a pump-out facility on one end and as a water taxi station at the other end. On the Basin H side the plan includes a 300 foot long side-tie dock plus 9 double 32 foot berths for transient boat use

Parcel 77 includes a 485 foot long by 40 foot wide dock with two 10 foot wide gangways and an ADA access gangway with two hinged ramp sections for small boat use for the proposed marina facility.  This dock can accommodate PWC’s, small sail boats, rowing boats/shells and kayaks; and can be used to store these small boats directly on the dock as required in addition to storage of boat related items.  It can also be used for boat instructional classes.  For the Parcel 49R existing small boat launch facility, a fourth dock has been added with gangway access from the bulkhead for boats to temporarily dock while keeping the existing three boat launch boarding docks free for the active launching and retrieval of boats.  Detailed cost estimates were also prepared to construct this proposed redevelopment plan.

Report for a Marina del Rey Slip Sizing Study, Marina del Rey, CA

Marina del Rey was formally dedicated in 1965.  The harbor complex encompasses over 800 acres of upland development and over water facilities that serve a variety of landside and water related uses including providing berthing for over 5,000 boats.  Over the past 40 years the harbor has evolved into an indispensable social, environmental and economic asset for Los Angeles County, and has become one of the successful urban marinas throughout the world.  The purpose of this study was to evaluate boat berth slip distribution criteria for the marinas undergoing reconfiguration and replacement in order to balance the recreational boating needs and demands for all of Marina del Rey, and in order to adequately support the Marina del Rey boating activities for the next 40 years. 

The boat berth slip distributions for 21 individual marinas within Marina del Rey that were originally constructed between 1964 and 1972 were reviewed in this analysis.  The historic changes in boat berth distributions for the Marina del Rey individual marinas were analyzed, and the already reconfigured marinas and   proposed marina reconfigurations within Marina del Rey were discussed.  The boat berth distributions for the Marina del Rey were then compared to other California marinas, and the Marina del Rey slip demand was analyzed based on the available historical data. An assessment of the change in vessel beam widths versus vessel length since the 1960s was evaluated, and recommendations for the continued reconfiguration of the Marina del Rey marinas was developed based on this comprehensive slip sizing study.
