On August 7, the U.S. Army Corps of Engineers awarded a services contract to Adanta, Inc. of Napa to expand and enhance an existing wetland on the Veterans Affairs (VA) property at Alameda Point. The wetland project is being implemented to offset impacts to wetland areas elsewhere on the VA property where a health clinic, offices and a columbarium cemetery will be built.
“The four-year services contract, valued at up to $2,373,044, includes development, seed collection, propagation, restoration, and enhancement to ensure the wetland is completely established as a self-sustaining tidal marsh at the VA Alameda Point site,” states the Corps of Engineers August 14 news release. “In total, 8 acres of new tidal marsh will be installed and established, as will 3.3 acres of tidal transitional habitat; and 14.8 acres of existing tidal wetland will be enhanced.” Seed collection and preparation is scheduled to start this summer. The work is expected to be completed in 2025.
One-third of the wetland impacts of the VA project will not be offset at Alameda Point. The Corps of Engineers will purchase credits in the San Francisco Bay Wetland Mitigation Bank for 3.6 acres of impacts. The mitigation bank manages a wetland restoration project in Redwood City funded by Bay Area projects that impact wetlands. The credit purchase detail is not mentioned in the news release.

Returning part of the Seaplane Lagoon shoreline to nature is one of the biggest changes that have emerged in the planning process at Alameda Point. The design proposal for the western side of the Seaplane Lagoon echoes the major theme of the Greenspace Project of Golden Gate University’s Center on Urban Environmental Law – the interconnected ecosystem.

The draft Town Center and Waterfront Precise Plan for the Seaplane Lagoon and eastern entrance area, presented to the Planning Board on August 21, offers a number of new concepts, including moving the proposed marina from the west side of the lagoon to the east side. The waterfront plan is being refined concurrently with zoning changes, an environmental impact report, and a master infrastructure plan, which are all aimed at providing the level of detail necessary for the city to start marketing property to investors in 2014.
In reporting to the Planning Board on design plans of the city’s consultant, Skidmore, Owings and Merrill (SOM), city staff stated: “Due to the vast scale of the study area and the Seaplane Lagoon as its centerpiece, the Town Center will be able to support a wide variety of unique waterfront experiences—some of which build and expand upon existing assets and activities, some of which introduce entirely new opportunities. SOM proposes the following four waterfront zones and experiences:
1. Natural environment—along the western edge of the Seaplane Lagoon with trails, docks, camping, outdoor sculpture and wetlands.
2. Promenade and recreational opportunities—along the northern edge, with early phased soccer fields, food concessions, bike and pedestrian paths, open lawn, and kayak access.
3. Urban edge—along the eastern side and portions of northern edge with marinas, docks, eating patios, overlooks, and ferry service.
4. Industrial—further south on the eastern side with maritime uses located near the MARAD ships and the USS Hornet.”

Climate adaptation grant funding needed – As currently envisioned, however, the de-paving, removal of buildings, and alteration of the western Seaplane Lagoon shoreline area is put off into the distant Phase 3 future — a decade or more from now — when presumably a surplus of infrastructure funds will allow for implementation. One option available for timelier implementation would be to begin now seeking grant funding from agencies that focus on shoreline climate change adaptation. There will be no commercial development on the western side of the lagoon, and therefore the project would become a public asset.
Lying directly to the west on the Nature Reserve is the Runway Wetland, whose habitat value would be greatly enhanced by a connection to the Seaplane Lagoon. Additionally, the draft Master Infrastructure Plan predicts a $10 million savings if the area were allowed to become tidal wetland as sea level rises.
