Groundwater Monitoring Program Update

The New Irvington Tunnel project team is currently monitoring some local groundwater decline. So far, four properties south of the Sheridan Valley project area have been affected. It appears that these declines are related to tunnel construction and dewatering activities. We have initiated mitigation measures at each property and we are maintaining their water supply.

Our commitment to protecting the groundwater in Sheridan Valley has not changed. If tunnel construction causes a decline in groundwater levels that affect an individual’s property, we will initiate the contingency measures defined in each site-specific Groundwater Management Plan. The project team continues to keep a close eye on groundwater levels and will take appropriate actions to maintain water supply.

If you notice any change in your water system, please contact the SFPUC’s 24-hour Answer Line (866.973.1476). Contacting the answer line will ensure the appropriate team members respond to you in a timely manner.
