HAYWARD -- Repair of a popular hills hiking trail is a few weeks behind schedule, thanks to a couple of unexpected obstacles uncovered during the work.
A section of Memorial Trail was heavily damaged during storms in 2006. The trail starts near the bandstand at Memorial Park, next to the Hayward Plunge on Mission Boulevard, and follows Ward Creek into the Hayward hills,
"We lost a good portion of a section of the trail; it narrowed from 10 to 12 feet wide down to four feet, making it impassable for our maintenance vehicles and emergency vehicles," said Karl Zabel, project manager for Hayward Area Park and Recreation District.
Workers building a retaining wall to shore up the trail this summer came across a buried 6-foot-tall concrete bulkhead, he said. The 115-foot-long retaining wall had to be redesigned to work around the bulkhead, which Zabel thinks was an old water line.
In the middle of the trail, workers unearthed a sewer line serving 20 homes. "It was probably put there in the 1950s," the project manager said. A new sewer line was built parallel to the old one, which was then torn out.
The project, which is being done by Northwest Demolition of San Francisco, is now expected to be finished by Aug. 25. In addition to the retaining wall, 20-foot-deep stabilization piers are being built along the trail's edge. "You won't see the piers, but they hold the trail," Zabel said. The trail remains closed until work is
The repair qualified for disaster relief funds from the Federal Emergency Management Agency and the California Emergency Management Agency. Zabel said he won't know the project's cost until work is complete, but he expects it to be higher than the original $123,841 estimate because of the additional re-engineering.
Work will start later this month on another popular trail, this one at Lake Chabot Regional Park in Castro Valley. About a third of a mile of the heavily used West Shore Trail south from Lake Chabot Dam to the marina will be repaved.
Also at Lake Chabot, workers started rebuilding a damaged trail to a wheelchair-accessible fishing pier earlier this summer. In addition, a trail from the parking lot to the picnic area is being regraded to comply with Americans With Disabilities Act standards. Those projects should be completed by mid- to late October, said Joe Britton, park supervisor.
Grade Tech construction company of Castro Valley is athe contractor for all the work at Lake Chabot. Rebuilding the trails will cost an estimated $415,000, and the repaving $68,700.
Trail restrictions and closures will be posted on signs in the park and at www.ebparks.org/closure. The Lake Chabot kiosk, 510-247-2529, also will have updated information.
