Presentation:
Guadalupe Dam is a 129-foot-high, 650-foot-long compacted earth embankment constructed in the mid 1930’s, owned and operated by Santa Clara Valley Water District. The Guadalupe Dam facilities are located in Santa Clara County about 9.5 miles south of the City of San Jose. Construction of the facilities occurred in the mid 1930’s with completion in 1936.
A seismic stability evaluation of the Guadalupe Dam completed in 2012 indicated inadequate seismic stability of the dam from postulated design earthquake events. As a result, Guadalupe Reservoir is currently subject to operational restrictions imposed by the California Division of Safety of Dams (DSOD). Retrofit of the 80-year-old Guadalupe Dam and associated facilities is necessary to address seismic safety concerns and other identified dam issues; to meet current regulatory requirements; to satisfy District operational requirements; and to remove the reservoir operating restriction and restore normal water supply capacity.
GEI is currently designing the seismic retrofit of the dam and will discuss key aspects of the project including engineering planning studies completed to identify the dam safety issues, alternatives considered for retrofit, critical dam safety design features and the current status of the overall retrofit design.

Speaker Bio:
Mr. Ajay Sehgal is currently Branch Chief in District 04 Encroachment Permits since 2016. 
​
Mr. Sehgal started at Caltrans 31 years ago in 1988 when he worked on the Schulyer Heim vertical draw bridge in LA.  It was recently replaced. In 1995, he worked on the seismic retrofit of the Presidio Viaduct in SF, southern approach to the Golden Gate Bridge.  By the way this bridge has been replaced under the Doyle drive project. Then, in 1996 he continued to work in SF on the Eastern Approach to the Bay Bridge. Again, this bridge was replaced with new Bay Bridge. In 2008, he worked on the new Self-Anchored Suspension Bay Bridge. He went to China, and later to South Korea, on special assignments regarding the inspection of the shear keys and bearings of the Self-Anchored Suspension portion of the Bay Bridge.

Mr. Sehgal is responsible for East Bay region consisting of Alameda and Contra Costa Counties. 
• Chairman of the Caltrans Falsework committee 2009-2015. 
• He was Co-chair of the 2013 & 2019 International OBG Conference, CA. 
• VP (Education) ASCE Capitol Branch 2011 thru 2014.
• Sept 2015 was the Key note speaker at the 4th OBG Conference in Tianjin, China.  
• Co-chair 5th OBC in Santa Clara, California

Keeping Up - California’s Fastest Growing City
Recently the U.S. Census Bureau named Dublin as the fastest growing city in California by percent of population change between July 1, 2017, and July 1, 2018.  Also, since 2010, Dublin’s population has increased by over 37%.  Dublin’s growth in the past decade, as well as changes in the Bay Area region, have required the Public Works Department to adapt to these changes, while striving to maintain a high level of service to the community.  This presentation will provide an overview of the methods, programs, and tools the Dublin Public Works Department is using to keep up.


Presenter: Andy Russell, P.E., City of Dublin, Public Works Director
Andy Russell is a civil engineer with over twenty-two years of experience.  After doing structural design for a few years in Tucson, Arizona, Andy started his municipal engineering career as a junior civil engineer with the City of Fremont.  He recently became the City of Dublin’s Public Works Director, after being Dublin’s City Engineer for almost six years.  He currently oversees a Public Works Department with an annual operating budget of $16 million, a 5-year Capital Improvement Program of $162 million, a staff of 18, and several contractors and staff augmentation consultants. Andy is a graduate of the University of Nevada, Reno, and spends his spare time with his wife and three kids.

MARTIN BODEMAR, S.E.
Martin Bodemar has over 24 years of experience in Project Management and Structural Engineering.  Martin works on a wide variety of structural projects with a special emphasis on unique bridge designs including concrete box girders, steel trusses, arch bridges, and stage-constructed bridges.  During his 19 years at Biggs Cardosa Associates, Martin has led the design of many multi-disciplinary bridge projects in the California. His recent work includes leading the quality control for the structural design of the approach bridges and bifurcating ramp structures for the replacement of the Gerald Desmond Bridge near the Port of Long Beach.  In his spare time, Martin enjoys various outdoor activities including biking, running, hiking, snowboarding, and others.
 
Presentation:
GERALD DESMOND BRIDGE APPROACHES, PORT OF LONG BEACH, CA
The low level approaches consist of long-span post-tensioned box girder bridges with most spans exceeding 200 feet. These structures are similar to Caltrans’ standard box girders.  The low level approaches include bifurcations for the various ramps that occur at the ends of the bridge project. The bridge frames with column heights of approximately 70 feet or less are considered “low level approaches”.
The high level approaches consist of primarily single-cell box girder superstructure supported by hollow rectangular columns. The superstructure was modeled and analyzed considering stage-construction and time-dependent effects due to the span-by-span construction method used. The span-by-span construction was used to accommodate a movable scaffolding system as a replacement for traditional falsework. With very tall columns (ranging from 70’ to approximately 150’ in height), traditional falsework construction methods were not economical for the high level approaches.
 

Presentation
Methods and considerations for Green Stormwater Infrastructure requirements:
 
Green Stormwater Infrastructure (GSI) is the implementation of constructed landscaping elements designed to divert stormwater runoff to softscape areas, encouraging groundwater infiltration. Despite trash management efforts, typical runoff from impervious surfaces carry with it pollutants of concern, such as polychlorinated biphenyls (PCBs) and mercury, through standard “gray” storm drain infrastructure into our waterways. Instead, GSI in both public and private projects allows for runoff filtration and groundwater replenishment. 
As a result of mandates under the NPDES Municipal Regional Stormwater Permit (MRP), local municipalities are required to commit to increasing their GSI development and implementation. This presentation is aimed to help industry professionals better understand GSI design and construction, as well as provide tools to navigate the requirements set by the Regional Water Quality Control Board.
 
Presenter
The Alameda County Clean Water Program (ACCWP) is a partnership of municipalities and agencies committed to reducing the contamination of our creeks, wetlands, and the Bay. The Program, under Alameda County Public Works, facilitates local compliance with the Federal Clean Water Act, coordinating water quality monitoring, grants for community-based projects, and providing technical guidance and resources for both professionals and the public.
Christine Chou, with the Engineering Division of the City of Newark Public Works, and other representatives will present GSI strategies on behalf of the ACCWP.  it.
