This Site, known as Parcel 3, is an undeveloped 8.9-acre property at the northwest corner of the Sierra Point development, overlying the former Sierra Point Landfill. The areas surrounding the Site consist primarily of commercial and recreational properties. The surrounding developed-landfill properties are currently occupied by open space, parking lots, office space, marina docks, an in-progress developments, and hotels.
The former Sierra Point Landfill encompasses an area of approximately 131 acres that lay within the city limits of Brisbane and South San Francisco. The landfill is bound to the north, south, and east by waters of the San Francisco Bay, and to the west by Highway 101. The Site overlays a portion of the former landfill in the northwestern area known as Parcel 3. Landfill development began with construction of an earthen dike between the years of 1965 and 1967 during which the dike was built around the north, east and south borders of the landfill. Dikes were constructed by successive dumping of large quantities of fill directly on top of the natural Bay surface and geologic unit locally called Younger Bay Mud. The interior of the landfill was then dewatered prior to placement of waste. Consistent with landfill regulations and practices of the time, no liner was installed. Waste materials were placed directly onto the Younger Bay Mud.
The landfill operated between 1965 and the mid-1970s and was used for the disposal of Class III solid municipal waste. Beginning sometime in 1967 or 1968 th
e landfill began accepting waste materials. Waste was reported to consist of household waste, rubble and clean soils. No liquids or hazardous material were reportedly accepted. Refuse was placed in two lifts, and cover material was brought in daily to cover the refuse. Waste volume estimates range from 1.9 to 2.6 million cubic yards across a total landfilled area of approximately 80 acres, of which more than 70 are covered by landfill cap.
By 1972, refuse was no longer dumped at the landfill. Sand and clay fill containing construction debris was placed over the refuse. Filling of the landfill is recorded to have been completed by the mid-1970s. The status of the existing landfill cap at the Site is provided in Section 2.1.1.
In 1981, a soil-bentonite slurry cut-off wall was installed at the Site along the northern portion of the western landfill boundary to prevent lateral migration of leachate.
