On February 22, the Central Coast Branch was excited to have Dr. Hugo Loaiciga from UCSB present The Carpinteria Valley Groundwater Basin Hydrogeologic Analysis. The presentation provided an overview of SGMA requirements and the hydrogeology of the Carpinteria Valley Basin, which straddles the Santa Barbara/Ventura County line. Dr. Loaiciga described the findings from historical investigations of local structural geology, recharge sources, and other aspects of the groundwater-flow system. Dr. Loaiciga also described a mass-curve analysis approach he developed for estimating the “safe yield” of a basin, and its application to the Carpinteria Valley Basin. He noted that although the Carpinteria Valley Basin is a very-low- priority basin under SGMA, there is a risk of seawater intrusion and the basin could benefit from a groundwater sustainability plan. The presentation engendered considerable and lively discussion on a number of topics, which made for an entertaining evening. Our Branch members very much enjoyed Dr. Loaiciga’s presentation. The meeting was very well attended.


The Branch is dedicated to increasing awareness of issues related to groundwater in the Central Coast Region, as well as to providing a forum for groundwater and hydrogeology professionals to gather and discuss developments in their field. We are actively seeking suggestions for future meeting locations or other ways to improve access to our meetings across the varied landscape of the Central Coast. If you have any announcements or questions please contact Tony Morgan ( or 805-525-4431) or Jeff Kubran ( or 805-963-0651).


The Central Coast Branch initiated a scholastic sponsorship program, with local sponsors supporting our annual scholarship fund for students who are engaged in groundwater studies. If your organization is interested in participating as a Scholastic Sponsor for a future event, please contact a Branch Officer. Sponsors will be recognized at our meetings and on the GRA website.


Meetings of the Central Coast Branch of the GRA will be held approximately every second month. If you would like to make a presentation at an upcoming meeting of the Central Coast Branch, please contact Tony Morgan.


Do you have interesting project data from your research on the geology and hydrogeology of the Central Coast area? The GRA would love to hear about the results of your research projects. If you would like to present your research at a future meeting, please contact Tony Morgan or Jeff Kubran and we will get you the appropriate details.
