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.

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.

Project Description

The newly completed State Route 1 Pfeiffer Canyon Bridge—a vital link between Big Sur and other communities in Monterey County (Caltrans District 5) – was damaged beyond repair from a landslide due to heavy rains which began in early January 2017. Through innovative design and collaboration, the new $24 million single-span bridge was built and opened to the public in 8 months when a project of this magnitude would normally take 8 years. Due to the severe impact to the community of losing this bridge, Caltrans was able to accelerate the project by ordering the steel in advance, accelerating the design, and using an innovative way to “launch” the assembled steel girder bridge into place.

This national, multi-award-winning bridge was recognized as an Accelerated Bridge Construction project—new to California and the Big Sur Community. Constructing the actual structure across the canyon presented unique challenges: working across the deep canyon, dealing with an active landslide, and needing to complete construction quickly. Dozens of bridge workers worked long hours, 6-7 days a week, to complete the project. The structure features fifteen 62-ton steel girders (fabricated in Vallejo) that span the rugged 310-foot canyon. Eliminating structural vulnerability to future slide activity, the design avoids use of support columns. The new bridge includes 12-foot lanes and 5-foot outside shoulders, making it accessible for all travelers.

Upon graduation he worked for medium sized A&E firms, including the Watry Group and Faye Bernstein and Assoc. where he collaborated on the design of several post-tensioned parking structures, the San Francisco International Airport ART system, the seismic retrofit of several historic buildings in San Francisco, and several Caltrans bridge phase 1 seismic retrofits. In 1998 he had the opportunity to work for Caltrans as a consulting assistant Structure Representative, inspecting and administering bridge construction contracts along the Cabrillo Highway in Monterey County. He enjoyed the field work so much he left the private sector and pursued his career with Caltrans as a Structure Representative in northern District 5. Over the past 20 years, he has worked on a multitude of maintenance, new construction, and retrofit projects.
