Potter, Bay, Bolivar Paving Project
City of Berkeley | Berkeley, CA
Situation: The City of Berkeley maintains Potter and Bay Streets along with Bolivar Drive which parallel and serve as the primary entrance to Interstate 80 (I-80). Over the years, these roads had fallen in disrepair. The pavement was in poor condition with cracking, severe potholes, and poor drainage leading to substantial amounts of water remaining on the roadway after storm events. The City was looking for a solution to repair the pavement, improve drainage, and enhance the area.
Special Challenges: The project area is heavily travelled during commute hours. During the design phase Pakpour Consulting Group (PCG) worked with the City traffic division to integrate staging and traffic control plans in the design documents to keep one lane open to access I-80 during construction. PCG’s project manager worked with multiple stakeholders, including Caltrans, during the design phase, to minimize disruption and traffic delays during construction. An extremely shallow 8-foot by 7-foot culvert crossed the project area and needed to be positively identified during design and protected during construction while maintaining current roadway grades.
Services Overview: Since 2013, PCG has served as on-call engineers for the City of Berkeley. For the Potter Bay Bolivar Paving Project, PCG provided full design and construction support services for the reconstruction of the roadway, including pavement repair, embankment repair, correcting drainage patterns, and coordination with multiple stakeholders including Caltrans.
About City of Berkeley: Located on the eastern shore of San Francisco Bay with a population of more than 120,000, Berkeley is a center for academic achievement, scientific exploration, free speech, and the arts.
Bubb Road Separated Bikeway Improvements
City of Cupertino | Cupertino, CA
Situation: The City of Cupertino’s Bicycle Transportation Plan included upgrades of the Class IIB buffered bike lanes along Bubb Road to a Class IV separated bikeway. Bubb Road is also the location of several offices for Apple, Inc., which offers free shuttles for employees. The shuttles run continuously and loop through congested parking lots to drop off employees. Additionally, employees often jaywalk to get between offices due to the lack of a mid-block crosswalk. The City wanted to find a solution that incorporated improvements for bicyclist, shuttle, and pedestrian safety.
Special Challenges: In order to reduce conflicting movements between bicyclists, shuttles, and pedestrians, the City desired to construct a shuttle platform along the existing roadway. However, the existing right-of-way width could not accommodate a two-way shuttle platform, two vehicle travel lanes, and two separated bikeways. Fronting properties were fully developed and additional right-of-way acquisition was deemed infeasible. Pakpour Consulting Group (PCG) worked with the City to design innovative offset shuttle platform in the street median.
Services Overview: Since 2018, PCG has served as on-call engineers for the City of Cupertino. For the Bubb Road Separated Bikeway Improvements, PCG provided design and construction support for the construction of the Class IV separated bikeways, an offset shuttle loading/unloading platform, 400 feet of new sidewalk, touchless pedestrian push buttons, a new crosswalk along the north side of the Bubb Road/Results Way intersection, and two mid-block pedestrian crossings with pedestrian activated warning lights, and new curb, gutter and sidewalk along Bubb Road. PCG worked closely with the City to respond to feedback from stakeholders such as Apple and the City’s Bicycle Pedestrian Commission (BPAC). PCG also provided bid assistance and construction support.
About City of Cupertino: Incorporated in 1955, Cupertino is a city within Santa Clara County with a population of more than 60,000. Cupertino is known as the home of Apple, Inc.’s corporate headquarters.
San Francisco Bay Trail Gap Closure
City of Richmond | Richmond, CA
Situation: The City of Richmond identified a section of the San Francisco Bay Trail corridor requiring significant upgrades and route realignment. The existing trail from Ferry Point to Kaiser Shipyard No. 3 detoured inland, away from the shoreline, for nearly two miles. The trail also required users to navigate a 120-foot climb over Seacliff Drive and also wind through an isolated portion of an industrial area along Canal Boulevard. Additionally, a portion of the existing trail was built over a capped environmental hazard area requiring a design and construction solution to avoid the soil cap already in place.
Special Challenges: The project required extensive coordination on the part of Pakpour Consulting Group’s (PCG’s) Project Manager with the Association of Bay Area Governments Bay Trail Project, East Bay Regional Park District, National Park Service, Point Richmond Neighborhood Council, Richmond Bicycle and Pedestrian Advisory Committee, and Trails for Richmond Action Committee. PCG held separate monthly meetings with all agencies involved to receive input and coordinate all aspects of design.
Services Overview: The City retained PCG to prepare the plans, specifications, and cost estimates for the construction of the trail gap closure. PCG worked closely with its structural engineering subconsultant to design a cantilever bridge structure accommodating the 10-foot elevation difference at the trails’ tie-in point over the environmental hazard area. The design solution avoided disturbance to the soil cap yet allowed for service truck loads. The innovative bridge structure “rests” on the soil cap without placing additional loads. From trail user perspectives, the bridge looks and feels like any other pedestrian bridge.
About the San Francisco Bay Trail: The San Francisco Bay Trail is a planned recreational corridor that, when complete, will encircle San Francisco and San Pablo Bays with a continuous 500-mile network of bicycling and hiking trails. It will connect the shorelines of all nine Bay Area counties, link 47 cities, and cross the major regional toll bridges. Each agency is responsible for maintaining the trail within its boundaries.
Street Resurfacing Projects
City of Dublin | Dublin, CA
Situation: The City of Dublin prides itself in having some of the best maintained streets in the Bay Area. The City’s PCI index score is among the highest in the Bay Area according to rankings published by the Metropolitan Transportation Commission (MTC). The City’s street resurfacing projects include annual street overlay and slurry seal programs.
Special Challenges: The City was looking for a consultant to continue the high customer service standards set by in-house staff while designing resurfacing projects. Pakpour Consulting Group (PCG) was a natural fit having completed numerous street resurfacing projects for various agencies throughout the Bay Area with 100% positive feedback and less than 2% non-owner initiated change orders.
Services Overview: Since 2010, PCG has served as on-call engineers for the City of Dublin. During this time, PCG has provided design and construction management services for their street resurfacing projects. PCG administered all aspects of the design and construction management process, including coordination with Caltrans and preparation of the plans, specifications, and cost estimate in conformance with Caltrans standards. PCG also prepared the Caltrans Local Assistance federal forms and invoices.
