THE CITY OF SAN JOSE ANNOUNCED AN EXTENDED CLOSURE OF THE LOWER GUADALUPE TRAIL, which concerns the Gold Street to Tasman Drive area. Closure of the trail is required as PG&E replaces a section of pipeline beneath the levee at the Lower Guadalupe River Trail. The project is expected to commence as of 25 August 2014; whereas, levee and trail access is to be restored by 30 October.
There will be no trail access on the east side from Tasman to Gold, until the project is completed. The project will require a prolonged closure of the Lower Guadalupe River Trail. At this time, the closure is anticipated to be for four (4) months.
The City of San Jose also reports:
WHERE: The project will require closure of the paved Guadalupe River Trail between Tasman Drive and Gold Street. Access to the trail from the Highway 237 Bikeway will also be closed during this period.
WHY: The California Public Utilities Commission (CPUC) has mandated a Pipeline Safety Enhancement Program (PSEP) that requires PG&E to retrofit its gas transmission pipeline L-109, from Milpitas to Daly City. The effort will remove impediments to the passage of pipeline inspection tools. To address an existing constraint, PG&E must replace an approximately 30’ long section of 22” diameter gas transmission pipeline that runs underneath the Guadalupe River’s eastern levee.
WHEN: The project scheduled to commence in August 2014 and scheduled for completion by October 30, 2014. The project requires removal of a portion of trail, so there will be absolutely no public access during the entire construction period.
SCOPE: PG&E and its contractors will excavate approximately a 10’ wide by 30’ long section of the levee to remove the existing 22” pipeline and replace it with 24” pipeline. Once this section of pipeline has been replaced, the entire Guadalupe River crossing section, including the new 24” OD pipe will be hydrostatically tested to meet the requirements of 49CFR192 to ensure against any leaks, confirm the manufacturing integrity of the pipe installed and validate the Maximum Allowable Operating Pressure (MAOP) of this section of L-109.
Upon completion of the pipeline project, the levee and paved trail will be restored to their existing condition.
DETOUR: PG&E and the SCVWD recommend that trail users utilize adjacent roadways and sidewalks, or may use the gravel maintenance road along the west bank of the river. No pipeline work is to occur along this levee.
PG&E is working closely with the Santa Clara County Water District and the City of San Jose to minimize the construction impacts to the levee, trail, and the public. The levee section shall be restored per the standards and specifications of the regulating body. Signage about the PG&E project and detour routes are being developed and will be in place prior to any construction activities.
