Wen Lin, and Sandy Yee from COWI North America, Inc presented the
Bulls Head Channel Marine Oil Terminal Improvements for the March
Dinner Program. In addition, Kristina Swallow, the National ASCE
President, gave a short talk about where ASCE is headed. Also in
attendance were Kwame Agyare, Region 9 Director and Elizabeth Bialek,
the San Francisco Section President. Thank you to all who attended.

The upcoming April Dinner Program will be be on Thursday, April 26th
at Scott’s Restaurant in Jack London Square, Oakland. Don Greb, PE of
Griffin Soil Group and present current soil stabilization practices.
The presentation will discuss the latest in soil stabilization design,
construction, applications, projects, and added value to engineering

Don Greb is the Principal Engineer at Griffin Soil Group, located in
Sunol, CA. Griffin Soil specializes in in the design and construction
of chemically stabilized soils throughout California.

San Jose Branch:

The San Jose Branch partnered with SFGI to host its annual dinner meeting in Fremont at Spin-A-Yarn Steakhouse. The dinner featured a very interesting presentation delivered by Nicolas K. Oettle, Ph.D., P.E. about the Geotechnical Extreme Events Reconnaissance (GEER) team’s findings from the 2016 earthquake in Kumamoto, Japan. Additionally, the San Jose Branch has finalized the essay prompt for the 2018 annual student essay contest to be about the California High Speed Rail Project. Last year, 12 students were awarded scholarship prizes, which totaled over $12,000 from company donations. This year, the awards banquet will be hosted by Stanford University in May.

North Coast Branch:


Fresno Branch:


Redwood Empire Branch:

Last month the Redwood Empire Branch hosted our annual Engineer’s Week Banquet jointly with the North Coast Chapter of the American Council of Engineering Companies. At the banquet, we presented scholarships to students in the Santa Rosa Junior College engineering and surveying programs. We’d like to thank all who attended and contributed to the event’s success.

This month’s program: Beyond the Basics! Pervious Concrete Design & Case Studies

By applying static stormwater system design techniques to pervious concrete, designers are stifling their ability to maximize performance and minimize cost, leading to systems that are overly complicated, overdesigned, costly, and underperforming. Building upon the principle of Large Area Thin Infiltration Systems (LATIS), this presentation will walk you through a series of real-world case studies and discuss how to design a pervious concrete system from the subgrade up. Throughout this discussion, we’ll study design details, base and subgrade prep, and the finer aspects of infiltration. We’ll also take a deeper look at specification writing, maintenance and long-term performance.

Speaker: David Liguori

David Liguori is the founder and president of Bay Area Pervious Concrete, and an industry leader in developing pervious concrete stormwater management systems. As one of the few NRMCA Certified Craftsman in Northern California, David has spent the last 12 years working with Pervious Concrete, playing a key role in the advancement of the material technology. David is a contributing member of ACI 522 Pervious Concrete Committee, on the National Pervious Concrete Pavement Association Board of Directors, and the NPCPA education committee chair. He was part of the industry advisory group on the Caltrans Permeable pavement guidelines. He is currently working with the California Nevada Cement Association, as well as the City of San Francisco, on updates to their pervious concrete specifications.
