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”
In early June a pair of returning ospreys looked ready for the day in their newly made nest atop a parking lot light pole at Alameda Point, but they had no chicks to attend to. The pair’s first nest this season — on a nearby ship — had been removed during construction. Their second attempt faced interference from another osprey. By June, hopes for fledglings this year had faded. An ad hoc group of osprey watchers is hoping a dedicated osprey platform can be erected at Alameda Point in a spot where competing interests and annoyances of daily commotion don’t intrude into the reproductive efforts of the ospreys.

In early March the osprey pair began building their first nest this year where they had nested last year — on a kingpost high atop the maritime ship Admiral Callaghan. The ship’s owner, the Maritime Administration (MARAD), had removed last year’s nest. This year MARAD moved quickly to stop the nest building to avoid potential delay to relocate a nest if ordered into service. “The Maritime Administration worked closely with the California Department of Fish and Wildlife on dismantling the nest and installing deterrence devices on March 19 prior to any eggs being laid,” said Alameda resident Harvey Wilson, who has been monitoring the ospreys at Alameda Point.

But that removal didn’t end the ospreys’ interest in the ship, at least not for the male osprey. He soon started bringing sticks to a lower-level hoisting post on the ship. The female, on the other hand, took a liking to a light pole in the parking lot next to the wharf. After weeks of back and forth episodes of mating and nest building at both sites, the female won, and nest building started ramping up on the light pole. At one point, it appeared that the female was hunkering down in the nest, a sign that eggs had been laid and incubation had started. But soon another female osprey appeared, trying to lure the male from his duties and disturbing the composure of the female.

The third osprey now seems to have moved on, and the original pair has continued to visit the nest, but the lateness of the season offers little hope that eggs will be laid again, if they ever were, this year.

The appearance of ospreys at Alameda Point, first documented in 2010, is part of larger Bay Area phenomenon of ospreys beginning to nest on the shores of San Francisco Bay. Osprey first began nesting in the San Francisco Bay Area in the year 2000, having moved their nesting range further south. There are currently 24 active nests on San Francisco Bay. One theory for the ospreys’ Bayside nesting interest is a reduction of silt in the Bay, making it easier for osprey to catch fish, their primary food source. The high silt levels are a legacy of the gold mining era during which streambeds emptying into the Sacramento River were blasted with water canons to expose gold particles.Ospreys normally return to the same nest every year, but the Alameda Point pair has now used three different sites. In 2012 they successfully raised their lone chick on an old light stand on the western jetty of the Seaplane Lagoon, their regular nest for three years. For unknown reasons, they chose the heights of a maritime ship in 2013, and in 2014 a parking lot light pole.

An ad hoc group of osprey watchers that includes members of the Golden Gate Audubon Society have been discussing with the city the possibility of erecting a permanent osprey nesting platform on the western side of the Seaplane Lagoon. “City staff has been and is willing to continue to work with interested members of the local community to potentially establish an osprey platform at Alameda Point,” said Jennifer Ott, Chief Operating Officer for Alameda Point. “The identification of an appropriate location for this platform will depend on a number of factors, including approval by the United States Fish and Wildlife Service.”In March of this year, the city of Richmond’s Public Works Department assisted with the installation of an osprey platform at Pt. Molate, which helped divert nesting efforts from a utility pole with live wires. PG&E, with extensive raptor nesting diversion experience throughout California, has offered to install a pole and nesting tub at Alameda Point for free.

“It is difficult to know what the ospreys feel or how they respond or what their capacity is for all the activity that goes on around them, but this season certainly challenged them,” said Alameda wildlife biologist Leora Feeney. “Providing safe platforms for them out of busy corridors would serve everyone better.”

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.

A Black-crowned Night Heron adult and its juvenile offspring were spotted along the south shoreline of Alameda Point during May and June of this year. The juvenile was seen foraging for food on the shoreline, as well as using the old dock for a resting area. Use of the old dock by a wide variety of birds, as well as a family of harbor seals, illustrates the habitat value of the waterfront and the wisdom of providing a new wildlife water platform when the Water Emergency Transit Authority removes the old dock for their new maintenance facility this year.

A Navy contractor will be cleaning up groundwater in part of the Town Center area next to the Seaplane Lagoon by injecting a solution of cheese whey, emulsified vegetable oil and water into nearly 200 wells that go down between 30 and 40 feet. The whey and vegetable oil will cause natural bacteria to flourish that will feed on the toxic trichloroethene (TCE) solvent causing it to break down.
According to the Navy, this type of food-stimulated bacterial bioremediation is common. The cheese whey is similar to the powdered whey products found in grocery stores. It will be delivered to the site already diluted in water. A hose will be connected to a fire hydrant and hooked to a metering device that will mix the whey and oil solution with municipal water as it is pumped into the wellheads.
The work is expected to begin in 2015, with periodic visits and testing until 2020. The first year of operation the contractor will make two visits of 35 days each. During each of these work periods they will inject 246,000 gallons of whey, oil, and water solution into the ground, allowing gravity to disperse the liquid.
The goal of the cleanup is to minimize the potential for hazardous vapors entering buildings, and chemicals migrating into the Seaplane Lagoon. TCE is an industrial solvent used to degrease metal parts. It was heavily used at aircraft and ship engine repair facilities on the site. A leak from a rail car is believed to be one of the major sources of the plume.
The 33-acre cleanup area is immediately to the south of the Navy jet on West Atlantic Avenue at the east entry to Alameda Point near Main Street. It is within the 150 acres of the Town Center that the city is seeking to develop in the near future. In April, the city council sent out requests seeking qualified developers interested in residential and commercial projects. The cheese and veggie oil cleanup area will not be transferred to the city until at least 2020 when cleanup has been certified to have met its goals.
Cleanup of fuel in groundwater ended about four years ago at an old fuel distribution point on the north side of the jet monument.
