Professional Experience
Environmental Impact Studies – Mr. Bowman
prepared numerous EIR traffic studies for commercial properties,
highways, and ports. Most recently he evaluated the impacts of redevelopment
plans for Central City / East Oakland, West Oakland, the Oakland
Army Base, the Promenade at Natomas in Sacramento. He evaluated
the effects of the Cummings Skyway Extension, Route 238-Mission
Boulevard (six miles of urban arterial), and Route 180 Alignment
(19 miles of rural arterial). Mr. Bowman’s port studies include
the Fleet and Industrial Supply Center (FISCO)/Port Vision 2000
EIS/R, 50-Foot Channel Deepening EIS/R, Berths 55-58 EIS/R, and
Port of Oakland JIT EIR. Other studies include the Pleasant Hill
Downtown Redevelopment Negative Declaration, the Concord Playfields
EIR, and numerous transportation impact studies for the City of
Sacramento.
Downtown Traffic Planning – Mr. Bowman prepared
the transportation element of the City of Concord General Plan update,
prepared a traffic operations study for conversion of C Street in
Hayward from one-way to two-way traffic operations, and evaluated
traffic circulation and parking supply improvement alternatives
in downtown Pinole. He advised the City of Pleasant Hill on the
redevelopment of its downtown, developed transportation plans for
Moraga Road and the Plaza Park area of downtown Lafayette, and developed
a traffic operations plan for Mission Bell Drive in San Pablo to
improve access to a variety of businesses and a new Community Center.
Mr. Bowman managed traffic operations in downtown Boulder, Colorado.
Traffic Signal Systems – Mr. Bowman developed
and fine tuned signal plans for two signal systems in Oakland, featuring
a variety of timing plans to provide time-of-day coordination and
to eventually function in a traffic responsive coordination system;
and signal coordination plans for the Pleasant Hill/Taylor Boulevard
signal system, featuring installation of WWV clocks. Mr. Bowman
was responsible for operation and maintenance of the City of Boulder
traffic signal system. He developed and fine-tuned signal coordination
plans for special events at the University of Colorado. Mr. Bowman
worked with the police department to develop traffic control strategies
for ingress and egress from football games and concerts. The timing
plans eliminated the need for police officers to provide hand signal
traffic control at signalized intersections and dispersed traffic
more rapidly than before implementation.
Traffic Simulation – Mr. Bowman has prepared
computer models to visually show how traffic would operate for various
traffic control plans. He has recently simulated traffic flow in
downtown Hayward, for San Pablo Dam Road at the I-80 interchange,
San Tomas Expressway in San Jose, and Camino Tassajara in eastern
Danville. He simulated traffic signal coordination in downtown Palo
Alto, on Oak Grove Road in Walnut Creek, and simulated the effects
of traffic management plans for Kirker Pass Road in Concord in preparation
for metering traffic flow at the City’s east edge.
Intelligent Transportation Systems – Mr.
Bowman was responsible for ramp metering and traffic operations
system design for the Contra Costa Transportation Authority, and
value engineering for the San Joaquin Hills Transportation Corridor
Intelligent Transportation System. He developed a primer on interagency
agreements and developed a Memorandum of Understanding in response
to the expressed needs of the affected agencies and assisted in
the development of traffic signal system requirements for Generation
1.5 traffic responsive operations on San Pablo Avenue.
Traffic Operations Studies –Mr. Bowman prepared
traffic operations studies and traffic control plans for the I-880/98th
Avenue interchange reconstruction and the Route 4/Bailey Road interchange.
He prepared a combined PSR/IPR/PR for interchange improvements at
Route 680/Rudgear Road in compliance with Caltrans project development
requirements. He conducted traffic studies for Segment 4 of Richmond
Parkway, and developed traffic control plans for phased implementation.
He prepared feasibility studies and secured state and federal approval
for four interchange improvements along six miles of I-225 in Denver,
Colorado.
Traffic Calming – Mr. Bowman evaluated more
than one hundred alternatives for managing traffic in the residential
neighborhoods along Homestead Avenue and Walnut Boulevard in Walnut
Creek. He conducted license plate surveys, public opinion surveys,
and met with neighborhood representatives to develop strategies
for reducing traffic impacts. Mr. Bowman also studied twenty alternatives
for reducing through traffic along 9th Street in a residential area
of Boulder, Colorado. He recommended the addition of a left-turn
signal phase and other modifications to improve access along an
alternative arterial route. Additionally, he conducted before and
after license plate surveys that demonstrated the effectiveness
of the study recommendations.
Bicycle and Pedestrian Studies – Mr. Bowman
has managed or been Principal-in-Charge of numerous studies that
addressed bicycle transportation, including two MacArthur Bikeway
Feasibility studies, the San Leandro Street Bikeway Study, the Old
Town San Pablo Circulation Study, the Concord Youth Playfields Master
Plan EIR, and the Port of Oakland Vision 2000 Local Planning Area
Transportation and Circulation Study. He prepared a Project Report
that lead to the completion of an Iron Horse Trail connection in
limited right-of-way through the I-680/ Rudgear Road interchange
in Walnut Creek. He studied pedestrian and bicycle facilities needs
for Moraga Road in Lafayette and prepared a study to determine the
location of greatest need for a bicycle/pedestrian grade separation
along a section of state highway in Boulder, Colorado. Mr. Bowman
worked with a design team to develop a grade separation at the University
of Colorado that required special design treatments to provide safe
intermingling between bicyclists and pedestrians. He developed a
Citywide priority plan for bicycle/pedestrian grade separations
for the City of Boulder. He managed the City of Boulder’s
bicycle facilities, designed traffic signal vehicle detectors for
bicycles, and fine-tuned detectors for bicycle detection.
School Studies – Mr. Bowman evaluated traffic
operations and parking for several elementary schools for the West
Contra Costa Unified School District. At the proposed Iron Horse
Middle School in Danville, he developed a circulation plan to serve
bus and parent drop-off areas and two parking lots in a constrained
space. He evaluated access, circulation, and parking at the Diablo
Vista Middle School and developed alternatives for improving access.
He evaluated the merits of providing a proposed modern roundabout
at an intersection proposed near the Meadow View Elementary School
in Santa Rosa and concluded it would be safer and more cost-effective
to install a standard traffic signal. In Colorado, he developed
access and circulation plans for a proposed elementary school for
the Poudre School District, an elementary school site in a mountainous
area for the Jefferson County Colorado School District, and improvement
plans for the Standley Lake High School in Westminster.
Parking – Mr. Bowman conducted parking surveys
and utilization studies, shared parking studies, and developed parking
facility concept plans. He developed parking management strategies
for a mixed use development in the San Francisco Fillmore District
based on survey data collected from Oakland jazz club patrons. He
developed recommendations for shared parking in downtown Pleasant
Hill and for the Evergreen Center in San Jose. He developed design
concepts for unifying three existing parking lots in Lafayette,
for improving parking and reducing cut-through traffic at Bel Aire
Plaza in Napa, for providing on-street angle parking for the 7th
Street Urban Design project in West Oakland, and for an expansion
of the Table Mesa Park-and-ride in Boulder.
