Updates on San Mateo County's
San Mateo Plain Groundwater Assessment 
February 2018
Knowledge of
Spring 2017
Groundwater Levels:
Fall 2016
We wanted to pass along some information to keep you informed of our activities.   We have been working diligently on Phase 2 of our project, filling some of the data gaps identified in Phase 1, and Phase 3 by performing scenario evaluations.  We wanted to thank each and every one of our partners and our consultants, EKI Environment & Water (formerly Erler & Kalinowski, Inc.), Todd Groundwater, and Hydrofocus, in these efforts for continuing to provide or help collect and evaluate additional data to support our efforts on behalf of the subbasin.

Second Round of Deep Well Monitoring
As you know, last spring we reached out to deep well owners for access to measure water levels.  Due to the cooperation 
of several public and private well owners, we were able to collect data to create the 2017 contour map (above on the left) which expanded the breadth of knowledge for the subbasin.  We were able to go out this fall and collect another round of measurements to begin to assess seasonal variations in the basin.  Look for this fall 2017 groundwater contour map during our next Workshop tentatively scheduled for April 2018.

GIS Maps
The San Mateo County's Office of Sustainability has worked diligently to publish various maps with the information made available through Phase 1 of our project.  These have included maps of well types (displayed below), well type by date range, water levels, and water quality.

CASGEM Monitoring Entity
San Mateo County Environmental Health hosted a meeting on January 12, 2018 with other public agencies to discuss the potential of developing a partnership to become a CASGEM monitoring entity.  CASGEM stands for California State Groundwater Elevation Monitoring and is a voluntary program to measure groundwater levels in aquifers of the state.  As discussed in the meeting by other entities already in compliance with this program, the benefit to compliance with this program is compliance with several current, and potentially future, requirements for state grants involving all manner of water projects.  Look for more information on this task in future Workshops and updates.

Finally, stakeholder engagement has been a priority throughout this process and has continued since our last Workshop in November 2017.  Recently we have presented to the City/County Association of Governments (CCAG) of San Mateo Countywide Water Coordination Committee and are scheduled to speak to the Belmont City Council on February 27, 2018 and the upcoming Challenges and Opportunities for Water Management in San Mateo County described below.

Please join San Mateo County Board of Supervisors President Dave Pine and C/CAG Chair Alicia Aguirre for an engaging discussion on water management issues in San Mateo County and an opportunity to connect with others in the community working on these issues.
