Closure/Postclosure of Disposal Facilities

Case Study: Shoreline Landfill Recreational Facilities

Shoreline Landfill operated as a municipal solid waste disposal facility and was certified closed in 1998. The landfill consists of three parcels: the 544-acre site which contains approximately 350 acres of waste; the vista site containing 84 acres of waste and the Crittendon site, containing 27 acres of waste adjacent to San Francisco Bay. The landfill was closed and multiple postclosure land uses were developed on it. The aerial view shows the current land-use facilities.

Shoreline at Mountain View, a 750-acre regional recreation and wildlife area opened in 1986 and features a 50-acre small boat sailing lake and boathouse; an 18-hole golf course; clubhouse and banquet facilities; historic Rengstorff House; eight miles of pathways; meadowlands; wildlife and habitat areas; and a self-guided interpretive sign system.

Burrowing Owl Habitat: One of the many assets and features of the Shoreline Landfill supports a significant burrowing owl habitat. Located near the southern entrance to the landfill, the habitat was established to protect and preserve this endangered species. The habitat supports a small population of burrowing owls. The animals are protected by “owl condominiums” consisting of plastic tubing submerged in mounds in the landfill soil but not into the cover itself. The tubes provide a permanent habitat for this specialized species that usually occupies abandoned ground squirrel burrows.


Rengstorff House at Shoreline Landfill

Rengstorff House: A German immigrant, Henry Rengstorff, one of Mountain View’s earliest settlers in 1867, constructed this classic Victorian Italianate home. The house was saved from demolition and moved to Shoreline at Mountain View in 1980. After the restoration was completed, the house was opened to the public in March of 1991.


Shoreline Golf Links is an 18-hole, championship-level golf course. Designed by Robert Trent Jones II and Associates, the course was constructed on reclaimed land in 1982-1983. The clubhouse, Michael’s at Shoreline, is a 10,667-square-foot restaurant/banquet facility constructed in 1992-93. A new pro shop and golf cart storage area were constructed in 2005.

Birds by Lake at Shoreline Landfill Boathouse on Shoreline Lake at Shoreline Landfill

Shoreline Lake is a man-made, 50-acre saltwater lake filled by water pumped in from San Francisco Bay. Construction was completed in 1982. The boathouse was completed in 1991 and includes a restaurant and water sports facility.


Recreational Trails: Shoreline Landfill is connected to the South Bay regional recreational trails system, tying into several trails that allow users to travel north and east along the west bay shore wetlands and easterly past the landfill and onto the San Thomas Creek trail.

Tents at Shoreline Ampitheater Shoreline Ampitheatre tent structures

Shoreline Amphitheatre opened in 1986 and is situated on approximately 60 acres at Shoreline at Mountain View. It can accommodate as many as 25,000 people with 6,500 fixed seats and is one of the world’s largest tent structures. An unexpected methane gas event nicknamed "The Great Balls of Fire," temporarily caused problems with closure of the amphitheater soon after it opened, but this event was quickly resolved.


Landfill Gas Flare at Shoreline Landfill

On site Gas-to-Energy Conversion: Shoreline Landfill’s methane gas is collected by a complex active gas collection system made of high density polyethylene pipes. The collection system consists of horizontal gas collectors, vertical extraction wells, a header piping network and perimeter trenches. The landfill gas is transmitted to several methane gas-to-energy conversion facilities. To further assist the researcher on microturbine uses in landfill gas conversion, this link will take you to the California Energy Commission website for more information.

Power generation facility at Shoreline Landfill.

The major portion of landfill gas is transported to a power generation facility to the west of the landfill. Here, three internal combustion engines at the Alza Corporation facility generate approximately 3 megawatts of electricity. The three conventional Jenbacher AG J320 GS low-compression piston engines convert the gas to electricity which powers three large office complexes nearby. Each engine has a 2970 Cu-in displacement at 1341 brake horsepower at 11.223 million British thermal units per hour at 1 megawatt nominal output for each engine. The three engines combined consume approximately 1100-1200 standard cubic feet per minute (SCFM) of landfill gas. The excess electricity is routed to the local utility’s power grid.

Microturbines that generate electricity at Shoreline Landfill.

The gas also is used to power two MT 70 Ingersoll-Rand microturbines on the landfill grounds, each of which generate up to 70 kilowatts of power. The two microturbines consume about 70 SCFM of landfill gas. This electricity is used to drive pumps for a nearby sewage and irrigation water pumping station and flare station. The flare is available when maintenance on the gas conversion systems is needed. It burns off the methane gas not burned in the turbines while maintenance is being done.
