At its January 20, 2015 meeting, the city council will weigh-in on the preliminary layout proposed by developer Alameda Point Partners (APP) for a 68-acre residential and commercial parcel between Main Street and the Seaplane Lagoon.
APP was selected by the former city council on November 18, 2014, to work up a plan for 800 condos and apartments and 200,000 square feet of retail and commercial space. The developer will also be responsible for changing the gateway street alignment from an oval to a straight line leading to a new public plaza at the Seaplane Lagoon.Continue reading “Alameda Point gateway plan begins taking shape”
The Seaplane Lagoon’s north side will be looking like its old self in a few months. The Navy has begun dismantling the waterproof concrete-walled containment system that was used for three years for dewatering and testing of soil dredged from the Seaplane Lagoon, marking a major cleanup milestone. Prior to that dredging work, much of the lagoon’s north frontage served as a staging area for replacement of storm drain lines contaminated with radium-226.
Construction of a new and improved soil cover over a waste disposal site concluded this spring, marking another milestone. The 110-acre site on the southwest corner of Alameda Point took 10 years of haggling about potential environmental impacts before a cleanup plan was adopted in 2010. Work began in early 2013. The dome-shaped soil cover required 500,000 cubic yards of barged-in soil to complete.
At the far northwestern corner of the Point, work is about to begin on another long studied and analyzed waste disposal site. In a few months, the Navy will be installing an interlocking steel retaining wall along 200 yards of the Bay shoreline to contain contaminated burned waste material that was bulldozed into the Bay more than a half century ago. Water dye tests showed no toxics are leaching into the Bay, but members of the Restoration Advisory Board (RAB) questioned whether the barrier would withstand a catastrophic earthquake. Partially covered by runway pavement, the entire 30-acre site will receive a three-foot soil cover. The work is expected to be completed in 2015. The area will be available for passive recreational use such as hiking trails when the city receives the land.
One of the longest-running and most problematic cleanup sites is at the old Naval Air Rework Facility (NARF), also known as Building 5, covering nearly one million square feet. Radium paint used for aircraft dial painting, and chemicals associated with engine repair work led to contamination that is still being remediated. The entire floor area will be scanned again for radiation in 2015, following up on at least three prior scanning surveys of walls, ceilings, pipes, and ducts. The year 2015 will also see the Navy returning to the site for a final round of groundwater cleanup treatments targeting contamination remaining after an intensive cleanup effort a decade ago.
Next door to the Bladium Sports Club on West Tower Avenue, another previously treated groundwater cleanup site will be treated again. Workers have already begun boring holes in the pavement for a network of hoses that will be used for introducing contaminant-eating bacteria into groundwater along with a bacteria food source.
On Saturday, July 12, the Navy’s annual cleanup site tour visited four of the cleanup areas. The most impressive stop was the 110-acre landfill site mentioned above. For the first time in over 15 years, members of the public were allowed to walk around and enjoy the magnificent views from the embankment that is closer to San Francisco than to city hall. The fencing is all gone, and with it the radiological warning signs. The Navy replaced an aging metal culvert that connects the site’s North Pond to San Francisco Bay with a concrete culvert.
Tour participants were able to see the area’s expanded wetland with a new tiny island. Caspian Terns started nesting on the island a few months ago, another type of milestone. “The last time Caspian Terns were seen in that area nesting was in 1999 when only one nest was detected,” said Alameda wildlife biologist and Alameda Point bird surveyor Leora Feeney. The 79-acre soil cover on the landfill will be seeded with flowering native grasses later this year. The vegetation mix was chosen by the RAB.
According to the Navy’s environmental cleanup coordinator, Derek Robinson, $513 million has been appropriated to date for Alameda Point cleanup, although some of it remains to be spent on upcoming work. His office, the Base Realignment and Closure Program, estimates another $80 million will be needed by the time remaining projects and follow-up monitoring are completed.
Later this year, the Navy is expected to transfer to the city the 33-acre North Housing site and seven-acre former Island High School site that sit next to Alameda Landing and Estuary Park, marking another milestone on the long and winding cleanup road to civilian use.
Update notes: Subsequent criticism of the Navy as to the necessity of a security fence by members of the public and regulatory agencies led to the removal of the security fence from the final work plan design. The Navy also agreed to shorten the soil gas vents to two feet, since only trace amounts of methane gas are now emitted from the landfill waste, most of which is industrial and did not produce methane in the first place. Additionally, the Navy agreed to examine the aging metal culvert that connects the North Pond of the West Wetland to San Francisco Bay. The culvert provides the water lifeline for the North Pond habitat and was at risk of collapse and being stopped up with debris. The Navy replaced the metal culvert with a concrete culvert (see photo above) and debris screen.
The Seaplane Lagoon was also the launch site on Sunday for outrigger canoes heading out to the tip of Alameda Point for a race to the San Leandro Marina. The Alameda-Point-to-San-Leandro race was sponsored by Wave Chaser.
Here are some photos showing what a great venue the Seaplane Lagoon is for outdoor events like boating.
Note that the temporary dock facility used by the boaters was installed by Artemis Racing when they began training out of Alameda Point for 2013 Americas Cup.
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”
The city’s west side of the Seaplane Lagoon at Alameda Point is mostly pavement – acres of it – with a few old buildings abutting a wetland on the federal property. The city claims its long-range plan for this area features a conversion to a wetland habitat, but their only commitment is to continue leasing the buildings to generate revenue while allowing a sea of unnecessary pavement to remain as an environmental blight.
Opportunities for implementing ecosystem enhancement, both short and long term, have yet to be explored for this area. We need to start moving in a direction now that benefits the environment by reducing climate impacts, improves the atmosphere around nearby businesses, adds to public enjoyment, and increases wildlife habitat.
Proposal for ecosystem enhancement
Short-term plan – Remove all pavement not required for commercial tenants. Recycle the pavement at the VA’s Alameda Point project site where they will be raising elevation and need base rock and fill. Once the pavement is removed and the soil exposed, native vegetation could be planted. Native vegetation will absorb CO2, produce oxygen, eliminate the heat island effect of the former pavement, add wildlife habitat, improve the aesthetic appearance of the property, and make it attractive as a hiking, jogging, and cycling destination.
Step 1 – Set aside money from lease revenue generated on the west side of the Seaplane Lagoon for pavement removal and introduction of native plant vegetation.
Step 2 – Explore recycling pavement at Alameda Point.
Step 3 – Explore grant sources for conversion of paved areas to native vegetation, i.e., state air quality board, EPA, State Lands Commission, etc.
Long-term plan –Establish an Alameda Point Wetland Mitigation Bank, which would incorporate the west Seaplane Lagoon acreage along with 50 acres on the northwest side of Alameda Point (Northwest Territories). Investment money would provide the capital for wetland creation, with money being recouped when mitigation credits are sold to developers elsewhere in the Bay watershed to offset their project’s impacts. As a general rule, a tidal wetland is worth at least as much as it would cost to create it. That’s why businesses exist that specialize in mitigation banks. In theory at least, the wetland project could be self-funding.
Step 1 – Commission a study on wetland mitigation bank formation using lease revenue from Buildings 25 and 29.
The drawing and images for the so-called “De-Pave Park” on the western side of the Seaplane Lagoon would be something to cheer about if the park had any chance of ever being created. The text of the city’s recently released Town Center and Waterfront Plan, however, allows existing industrial buildings along the western edge of De-Pave Park to remain “if needed.”
Such a caveat sets the framework for never moving forward with the plans. If the buildings are being leased, the buildings will be “needed.” If the buildings are needed, then the pavement around them will also be needed. The city is continuing to market these buildings to tenants and, thus, there’s not likely to come a day when we try to secure grant money to develop the park.
This is a change from the first presentation of De-Pave Park in 2013 when the Town Center and Waterfront Plan was rolled out. The existing structures were not shown in that drawing. The community was led to believe that all structures would be removed to provide a natural wetland-oriented transition to the existing Runway Wetland on federal property. Not so anymore. The structures can stay.
The infrastructure plan now has a levee protecting the 55-foot tall “Building 25” from sea level rise. There would be no reason to protect this eyesore if it was slated for permanent removal. Furthermore, the building is part of the mixed-use commercial and residential waterfront zone where even a hotel is permitted.
The plan’s conceptual drawing and photo collage showing campers, hikers, and grasslands does not include a view to the west, and with good reason. It would show the industrial legacy that will interrupt the potentially expansive views toward the west. It’s deceptive advertising.
Parks, as we’ve learned during the new zoning designations for Alameda Point, are zoned Open Space. This “park” is not zoned Open Space. It’s another indication that the so-called “De-Pave Park” is phony.
Changing the western shoreline of the Seaplane Lagoon to a wetland-grassland landscape connected to the Runway Wetland would implement climate change adaptation goals and carbon sequestration goals. Without a commitment by the city to implement De-Pave Park in the Town Center and Waterfront Plan – including removal of all buildings on the western side of the Seaplane Lagoon – a great opportunity to help rebalance the San Francisco Bay ecosystem will fall through the loopholes.
City Hall is requesting comments on the draft plans for the Town Center and Waterfront Plan by May 15, in preparation for a June 9 Planning Board meeting. The plan will be the guiding document on how, where, and what gets built around the Seaplane Lagoon. The city council is expected to approve the plan in July. Comments can be submitted to city planner Andrew Thomas at email@example.com for forwarding to the Planning Board.
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.
