Construction Update: Lane Closure on Colma Boulevard Begins March 18

The SFPUC’s Regional Groundwater Storage & Recovery Project is making great progress in the Peninsula! This week the project team began installing an eight-inch diameter pipeline along Colma Boulevard in the Town of Colma. Once the Project is complete, this pipeline will connect our regional water customers with a water supply that can be used during a drought or other emergency.

During pipeline construction, one lane on Colma Boulevard will be closed (just west of El Camino Real) from 8 a.m. to 4 p.m. Monday through Friday. One lane of traffic will be maintained in each direction at all times.

• Pipeline construction will begin as early as Friday, March 18 and will last approximately two weeks. 
• Two construction message boards are posted on Colma Boulevard to notify traffic about upcoming lane closures.
• The Project is sensitive to traffic during services along Colma Boulevard and will adjust operations, if needed

Above is an example of what pipeline installation work looks like on Colma Boulevard.
