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.

Mass Transit – Mr. Bowman developed stage construction and traffic handling plans for the BART Dublin/Pleasanton Extension and the ATSF Southern California Commuter Rail Project. He assessed impacts on street traffic operations for the San Francisco Caltrain Extension. His studies include demonstrating the feasibility of expanding the Table Mesa Park and Ride Structure in Boulder, Colorado, a Transit Center Study for regional transit access into the central business district, and the East Colfax Travel Time Study for proposed limited bus service. In addition, Mr. Bowman developed a statewide transit safety records system for Virginia.
