City to seek funding for wetland park at Alameda Point

The proposed ecological wetland park at Alameda Point, known as DePave Park, is another step closer to becoming a reality.  On Sept. 15, 2020, four members of the city council gave thumbs up to moving forward with seeking a $2 million grant to pay for a master planning process.

“I am super-stoked about this project; it’s better than I ever imagined,” said Councilmember Jim Oddie, who has led recent efforts at City Hall to get action on this park.  “I was really touched when I saw the drawing.  I broke down in tears it was so beautiful.”

As currently envisioned, park construction will entail removing old pavement and softening the edge of the western side of the Seaplane Lagoon which will allow water into the park and become adaptable to sea level rise.  A tidal channel through the park will connect the Seaplane Lagoon with the existing wetland on the federal property, thereby creating a combined wetland ecosystem with multiplied benefits.

Wetland contract awarded for Alameda Point

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.

Views of wetland cleanup area to be dug up, upgraded in 2019

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.

Most of the water in the accompanying photos, taken in March 2019, is from rainwater.  However, this wetland is also low enough in elevation that it receives water via tidal pressure from the Bay. Continue reading “Views of wetland cleanup area to be dug up, upgraded in 2019”

City misses chance to embrace wetlands at Alameda Point

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.

Navy to create new wetlands

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.

VA wetland study censored

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. 

“(b)5” is Exemption 5 in the Freedom of Information Act.

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.”

Navy adds a wetland and grassland

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.
