Ravenswood Ponds Construction
New Trail & Wildlife Habitat
ABOUT THE PROJECT
The Don Edwards San Francisco Bay National Wildlife Refuge in July 2018 launched levee maintenance and habitat enhancement at the Refuge’s Ravenswood Ponds, on lands directly south of the City of Menlo Park’s Bedwell Bayfront Park. To shore up and repair pond levees, trucks imported large quantities of soil. Soil imports continued in 2020 to prepare for construction of a new public trail and slopes for wildlife, part of the South Bay Salt Pond Restoration Project’s Phase 2 projects. Trucks need to drive through the Park entrance and alongside part of a San Francisco Bay Trail/Park perimeter trail that loops around the edge of the Park to reach Refuge lands. They need to use the Park’s front parking area. To protect public safety, the impacted Park areas and trail segments are closed when trucks are present. A flagger, barriers or fences block access to those areas. When work is occurring, affected trail segments are generally open for public use on weekends, and on weekdays after 5 p.m. When work is not occurring, trails are open.
Please follow all trail closure signage and fencing. The closures are for your safety while heavy trucks are operating.
- 294 acres of new tidal marsh
- 37 acres of ponds improved for ducks and shorebirds
- A new trail and viewing platform between Bayfront Expressway and the southern edge of Bedwell Bayfront Park
- Improved All-American Canal levee to protect the pond bordering the Facebook campus

News & Updates
Note: This information based on construction activity is current as of April 2, 2020. As new information becomes available, we will provide additional updates.
Workers have completed a parallel track for trucks that has removed truck traffic from most parts of the San Francisco Bay Trail in the City of Menlo Park's Bedwell Bayfront Park.
Soil hauling began in July 2018 to shore up shorebird pond levees. In Fall 2018, trucks began bringing in soil for South Bay Salt Pond Restoration Project Phase 2 projects, including a new slope to help wildlife escape high tides, and a new public trail. That work continues in 2020.
Construction lasts roughly May through October (until the rains begin).
Specific continuing construction impacts to the Park include:
Park Entrance: Trucks travel through the Park entrance. However, the entrance remains open to public vehicles through the construction activities. The pedestrian/bicycle trail entrance has been shifted to the south. Work areas will be separated from public users by fences, signs and/or barriers, and flaggers are present near the park entrance when trucks are active.
Parking: The Park’s front parking area is closed off, but other Park parking will continue to be available further up Marsh Road.
Trails: Aside from the 1/4-mile San Francisco Bay Trail segment along the Park's southwest corner, the rest of the Park's extensive trail network will not be impacted. Trails sections impacted by trucks will be open for use after 5 p.m. and on weekends and holidays.
Truck traffic: There is increased truck traffic exiting Highway 1 at Marsh Road, and at the vehicle entrance/exit area of Bedwell Bayfront Park.
What to Expect During Construction
The Refuge and the Restoration Project are working to minimize traffic and trail access impacts. We appreciate your understanding and cooperation as we prepare for habitat and trail construction.
When do trucks operate?
Work is limited to Monday through Friday during the day. No weekend work is allowed. Trails will be open during the work hours when trucks are not present.
How long will the overall project last?
From 2018 to 2021. Construction of the restoration project elements within the ponds continues through 2020, and is expected to continue into 2021.
Traffic Impacts: What are expected traffic impacts?
Trucks exit Highway 101 directly along Marsh Road. There is increased traffic at the vehicle entrance/exit area of Bedwell Bayfront Park when trucks are present.
Park Impacts: Which roads, parking areas, trails and trail access points may be impacted?
Trucks exit Highway 101 at Marsh Road and use Marsh Road to enter Bedwell Bayfront Park. They then drive along the area now devoted to the Park’s front parking area, and turn right onto a new dirt roadway parallel on the outside of the Bay Trail/Park perimeter trail, traversing along the west side of the Park to Refuge lands. In order to protect pedestrians and bicyclists, a new pedestrian/bicycle entrance, to the south of the existing entrance, was established [indicated in blue on the map]. The park access trail closest to Marsh Road is closed to pedestrians and cyclists, as is the Marsh Road crossing area.
Updated maps will be provided showing the current portions of trails that are closed or impacted by construction. The primary work season is expected to extend from May to October.
Will there be signs and people on hand to help?
The soil hauling company Pacific States has certified traffic controllers who are on site with flags when trucks are active. Flaggers are stationed at the pedestrian crossing area at the entrance to the park (as indicated on the map). Signs indicating trail closures are located at the entrance to the park and at intersections of the Bay Trail/Park perimeter trail and park trails.
How can members of the public access the City’s free compost pile at the entrance to Bedwell Bayfront Park?
Trucks may hinder the public’s ability to drive up and collect compost from the pile during weekday work hours. The compost pile would always be available on weekends and during the week before 8 AM and after 5 PM.
Background & History
ENVIRONMENTAL & COMMUNITY BENEFITS
The levee maintenance and habitat enhancement work provides a variety of environmental and community benefits including:
- Enhanced and restored habitat for endangered and native wildlife
- New recreational trail and viewing area
Initial Construction Work
Work in spring 2018 was levee maintenance focused on shoring up levees. The mission of Don Edwards San Francisco Bay National Wildlife Refuge is to manage its acreage to conserve fish, wildlife, and plants. The Refuge contains many levees that are battered by winds and tides. The Refuge keeps these levees in good condition by adding new soil, so they can continue to protect the integrity of the ponds that are important foraging and breeding habitat for many waterbirds.
South Bay Salt Pond Restoration Project Phase 2 Ravenswood Construction
Work began in fall 2018 and continues on South Bay Salt Pond Restoration Project’s Phase 2 plans for Ravenswood.
What the Phase 2 construction at Ravenswood will accomplish:
Create 294 acres of tidal marsh south of Bedwell Bayfront Park. The new habitat will feature 8 acres of new upland areas along the Park and the All-American Canal levee so wildlife can escape storms, high tides and sea level rise. The work at Pond R4 will be accomplished by breaching the levee between the pond and San Francisco Bay to let in Bay tides. Work includes improving the All-American Canal levee to protect 270 acres to the west, Pond R3. This pond borders the north and east sides of the Facebook campus. It will be kept as dry salt flat for threatened western snowy plovers to nest.
Transform 37 acres of ponds between the Bayfront Expressway and Bedwell Bayfront Park into shallow water habitat for ducks and shorebirds.
TRAIL AND VIEWING PLATFORM:
A new trail will run from the Bay Trail on Bayfront Expressway south of Chilco Street through ponds to reconnect with the Bay Trail at the southern edge of Bedwell Bayfront Park, creating a loop around Ponds R5/S5. A new viewing platform midway along the trail will offer views of three different types of bird habitat, the duck ponds, newly developing wetlands and dry nesting habitat for the threatened western snowy plover.
Alviso Levee Maintenance: Trail Blockages
UPDATED TRAIL CLOSURE ALERT: The Alviso Slough Trail, usually a loop, will temporarily become two dead-end trails ending at Pond A9 as construction work at that spot requires a full block of the trail. The trail is accessed from Alviso Marina County Park and the Refuge's Environmental Education Center. Partial trail closures continue as workers shore up levees and replace a water control structure to ensure the longevity of trails and pond habitat. The partial closures occur on weekdays between 7 a.m. and 5 p.m. through the end of 2020. Trucks will enter through the Alviso Marina County Park entrance and will travel along the Pond A12 levee to ponds A11, A10 and A9. Even green areas in the map below, along ponds A13 and A15, will be impacted by the construction.
