Groundwater Resources Advisory Committee

Meeting synopsis: April 25, 2013

The Napa County Groundwater Resources Advisory Committee (GRAC) held its 11th meeting on April 25, 2013. Mr. Peter McCrea, Chair, reported on the update and presentation he gave to the Board of Supervisors during their April 2, 2013 meeting, including the Board’s strong support for keeping confidential the groundwater monitoring information associated with the County’s Voluntary Groundwater Monitoring Plan. Ms. Vicki Kretsinger Grabert, Luhdorff and Scalmanini Consulting Engineers (LSCE), provided handouts and responded to questions the GRAC had posed at the last meeting about the Updated Hydrogeologic Conceptualization and Characterization of Conditions Report. Mr. Patrick Lowe, Napa County, reviewed outreach materials/maps with the GRAC and a draft presentation that members will use to brief groups on the Voluntary Groundwater Monitoring Program. The GRAC discussed and agreed on additional outreach materials needed to help sign up volunteers and requested updates to simplify and shorten the presentation. Ms. Christine Secheli, Napa County, reviewed proposed revisions to the County’s Groundwater Ordinance. The GRAC commented on the revisions and made suggestions for clarification or provided further direction. The GRAC’s next meeting will be held on June 27, 2013.
