First Street/Bernal Ave Intersection

The Bernal Avenue/Sunol Boulevard/First Street intersection in Pleasanton serves as a gateway to downtown from highway 680 and it is subject to increasingly higher traffic volumes during the commute hours causing localized congestion. The goal of the project is to improve operations for vehicles, bicycles and pedestrians. Improvements will include left turn pocket upgrades and integration of complete streets concepts to accommodate safe paths of travel for bicyclists and pedestrians toward downtown.


Stevens Creek Sidewalk Renovation

Utilizing the advantages of an on-call agreement, HMH completed the Stevens Creek Sidewalk Renovation project under an accelerated schedule for the City of Cupertino.  The City had made commitments to the community to deliver the project by early spring 2017 and engaged HMH in late fall 2016 to prepare plans for removal of pavers and installation of sidewalk improvements along the high-volume Stevens Creek downtown area, also known as the Heart of the City. Recognizing the City’s need, HMH focused on quick production of design drawings which provided adequate information for accurate bidding. The low bid received was within 5% of the Engineer’s Estimate and the project was built with time to spare ahead of the City’s committed schedule.
Replacement of existing sidewalk pavers with standard cast-in-place concrete sidewalk. This project was a result of a lawsuit against the City and was therefore very critical.


US 101 Blossom Hill Road

Working for the City of San Jose, HMH is leading the Project Approval / Environmental Document Phase of the US 101 / Blossom Hill Road Interchange Improvements.  The project will widen the existing Blossom Hill Road Overcrossing from four lanes to six and will install a completely grade separated, Class I bicycle and pedestrian trail. By realigning and lowering the existing NB on-ramp, the project will provide a smooth and continuous path for bicycles and pedestrians to cross over 5,000 peak hour vehicles reducing user stress and connecting the existing Xanders Pedestrian Overcrossing to the Coyote Creek Trail.
Stay informed of project updates.


US 101 Interchanges at Capitol Expressway and at Yerba Buena Road

HMH worked with VTA to complete the second phase of the U.S. 101 Operational Improvements between I-280/680 and Yerba Buena Road.  This project was needed for congestion relief by extending southbound mainline improvements, converting the Capitol Expressway interchange into a partial cloverleaf, and adding ramp improvements at Yerba Buena Road.
HMH provided enhanced intersection designs to improve safety for pedestrians and bicyclists.  Staff worked with Caltrans, VTA and Santa Clara County Roads &  Airports Department representatives to incorporate the following public improvements into the project:  pedestrian refuges, curb return bulb-outs, widened bike lanes and enhanced sidewalks.  The ramp terminus intersections have also been carefully designed to limit turning radii and reduce the fastest path of vehicles crossing pedestrian crosswalks, while still accommodating truck turns for STAA (Surface Transportation Assistance Act) vehicles.
VTA reconstructed wider sidewalks on the existing overcrossings and took advantage of the opportunity to replace the bridge railing with unique aesthetic treatments consistent with the Tully Road interchange.  Replacement planting was done within the interchange, along with street trees on widened sidewalks to improve the pedestrian experience.
HMH services included supplemental surveys using convention and 3-D laser scanning equipment, preparation of mandatory and advisory design exception fact sheets and geometric approval drawings.  HMH complied with VTA Quality Assurance procedures and met the schedule, budget and SBE participation requirements.


280 Wolfe Interchange

In its current state, the I-280/Wolfe Interchange is severely congested and is projected to operate at a poor level of service as local developments continue to outpace the capacity of the existing infrastructure.  As the primary point of access for the Apple Park Campus and Vallco Shopping Center, the interchange serves as a gateway to Cupertino. HMH quickly recognized the need for seamless implementation of complete streets elements and thorough consideration of the bicycle and pedestrian user experiences critical to the long-term success of the project.
HMH recently completed an Alternative Analysis and Caltrans Project Initiation Document (PID) to program project support staff and funding. HMH is currently leading the environmental phase (PA/ED) of the project which includes refinement of preferred project alternatives, evaluation of environmental impacts, including the Junipero Serra Channel bisecting the project, and detailed traffic operations modeling. HMH worked closely with VTA and Caltrans to accelerate project deliverables and combine submittals to simplify project review cycles.
The project is currently moving quickly on an accelerated project schedule to position for available Measure B funding, supplementing the City and local developer’s contributions.


Montague Expressway Widening

This project widened Montague Expressway to provide for eight through lanes (three through plus one HOV lane in each direction), with bike use shoulders and improved pedestrian sidewalks from Falcon Drive to Pecten Court (approximately 0.8 miles) including replacement of the double-box culvert crossing of Berryessa Creek with a bridge structure. The project design required close coordination with the SCVWD, the BART SVBX C700 project, and the BART SVBX D720 design for the south leg of Milpitas Boulevard.
In addition to the widening and raising of Montague Expressway and Milpitas Boulevard, the project involved modification to drainage systems, relocation of utilities to include twenty-six PG&E electrical poles, compliance with current C.3 regulations, and traffic signal improvements at both Milpitas Boulevard and Pecten Court.
Our services also include field topographic surveying, boundary mapping, and production of all plats and legals needed for right-of-way and easement acquisitions.


Sunnyvale Downtown Streetscape

The goal of this improvement project was to enhance roadway segments and to implement streetscape design themes in order to unify the downtown commercial and residential areas. The scope of the project included the installation of wider sidewalks, street trees with grates, irrigation systems, street lighting, street furniture, and bicycle parking facilities. Roadway pavement, traffic loop detectors, and roadway striping were also installed. The design included the necessary conform area between the existing grade and the new back of sidewalk.
Phase I improvements are located along Sunnyvale Avenue between Iowa Avenue and Evelyn Avenue. Phase II improvements are located along Iowa Avenue between Sunnyvale Avenue and Mathilda Avenue.
Prior to construction, HMH provided mapping and legal documents to the City that allowed for the acquisition of right-of-way necessary to install the proposed improvements.


U.S. 101 Tully Road Interchange

HMH led this critical Proposition 1-B bond-funded project for major improvements to U.S. 101 between State Route I-280/I-680 and Yerba Buena Road.  Working closely with Caltrans, VTA and the City of San Jose, HMH developed a multi-phase implementation approach by preparing a Project Study Report/Project Report (PSR/PR) with environmental clearance to add a southbound lane, modify interchanges at U.S. 101/Tully Road and Capitol Expressway to partial cloverleaf configurations, with auxiliary lanes and ramp modifications.
HMH completed Plans, Specifications and Estimates (PS&E) for Phase 1 including reconstruction of the U.S. 101/Tully Road freeway interchange; the addition of a southbound travel lane and a new auxiliary lane from Tully Road to Capitol Expressway.  Because of the funding priority, great emphasis was placed upon schedule delivery and budget accountability.  HMH responded with high-quality PS&E ready for advertisement on schedule by Caltrans.  Bids were received in July 2010 for $23.5 million, almost 34% under the estimate.
HMH services also included control surveys and aerial topographic mapping according to Caltrans A, B and C submittal procedures, preparation of mandatory and advisory design exception fact sheets, geometric approval drawings, utility coordination, and technical studies for the State CEQA Initial Study/ Negative Declaration and Federal NEPA Categorical Exclusion Environmental Clearances.  HMH met the accelerated schedule and budget requirements with adjustments for scope changes related to VTA’s multi-modal approach.
