The Navy will implement the environmental remediation plan for Site 32 on the western end of the former airfield. The plan calls for covering the entire 60-acre site with three free of clean soil without raising the elevation of the existing wetlands. Thus, the existing wetlands will be excavated to a depth of three feet, and then three feet of replacement clean soil will be brought in to re-contour the wetlands.
The city and its consultant recently released a report outlining what will be included in the new climate action plan for Alameda. What it reveals, unfortunately, is their resistance to thinking big.
The process for updating Alameda’s climate action plan began as a promising effort for a comprehensive look at what it means to adapt our entire environment to climate change. It is winding up with a narrow focus on protecting local real estate, which they refer to as “vulnerable assets.”
The city has rejected a broader scope of action that would include “opportunity assets,” as in opportunities to improve the natural environment, not just the built environment. Areas at Alameda Point not slated for development must be viewed as an opportunity asset that can be re-purposed for the good of the environment.

The Navy is nearing completion of plans for a cleanup area called Site 32, 60 acres that lie on the old airfield west of where the monthly Antiques Faire is held. The site requires remediation because investigators discovered radium-226 in the soil and on various objects. The Navy mixed radium-226, a naturally occurring mineral, with paint to allow dials and markers to glow in the dark. Repeated exposure to high levels of radium can cause cancer.
The Navy collected radium-impacted waste, such as used paint brushes from refurbishing dials and gauges, scraping solids, and rags, from its dial painting shop on a regular basis and discarded it at the Site 1 underground dump adjacent to Site 32. The Navy presumes that the radium-impacted items were spread beyond the dump site when the runway was expanded in the 1950s and a bulldozer was used to grade the area above the dump.

The planned U.S. Department of Veterans Affairs (VA) Alameda Point healthcare facility and columbarium will eliminate about 12 acres of existing wetland on the former Navy aircraft runway area. The federal Clean Water Act requires that the VA compensate, or mitigate, for the adverse effects of their project. But the proceedings have been cloaked in secrecy.
In February 2017, five months after submitting a Freedom of Information Act (FOIA) request for information related to wetlands, the VA provided a copy of a consultant’s study on the feasibility of expanding and enhancing a different wetland on VA property. But the document arrived with over half of the study either blacked out or stamped “Page withheld in its entirety.”
The Navy’s cleanup program has not only removed toxic substances from below ground, it has dramatically improved some of the above ground environment by creating new native grassland and wetlands. January rains filled the Navy’s new seasonal wetland on the northwest shoreline corner of Alameda Point and fostered growth of newly planted native grass seed on the surrounding soil.
The 2.25-acre wetland lies within an approximately 37-acre shoreline cleanup area known as Site 1 at the confluence of the Oakland Estuary and San Francisco Bay. It is where the Navy buried its waste between 1943 and 1956. Most of the waste pits were covered by pavement in the mid-1950s when a new runway was added.Continue reading “Navy adds a wetland and grassland”
(Hint: It’s behind Building 25 and was temporarily enlarged on Thursday.)
Rain on Thursday, December 11, led to flooding on three sides of Building 25 at 1951 Monarch Street, as well as on the south side of the Control Tower. Building 25 is adjacent to the wetland on federal VA property called Runway Wetland.
Building 25 was slated for removal in the original Waterfront Town Center conceptual drawing to make way for a wetland park called De-pave Park. By early 2014, city staff decided instead to lease the building, convincing the city council to follow. The plan now calls for protecting the building with a levee, which could be decades away. Continue reading “Find the wetland near Building 25 at Alameda Point”
It’s more likely a new wetland will be created on the western shoreline of the Seaplane Lagoon at Alameda Point, thanks to lobbying efforts led by the Sierra Club.
On July 1, 2014, the Alameda City Council added language to the Alameda Point Town Center and Waterfront Specific Plan that raises the commitment to remove pavement from the western side of the Seaplane Lagoon for wetland—an area called De-Pave Park. Lobbying efforts convinced the council to include the following options to help facilitate the wetland park creation: 1) creating a wetland mitigation bank; 2) adding the area to a possible national wildlife refuge on the federal property; and 3) working with local community members who may identify funding sources for creating the passive park area.Continue reading “Wetland park plan at Seaplane Lagoon gets a boost”
