California High-Speed Rail Central Valley Stations

in , ,

The first stations built for the California High-Speed Rail (HSR) project will be in the Central Valley at Merced, Fresno and Bakersfield. These stations are designed not just as transit points but as multi-modal hubs that connect HSR with other forms of transportation. The design work for these stations is in progress, with a potential construction start in 2028. The Central Valley stations JV, led by Foster + Partners and ARUP. The project is focused on sustainability, aiming for net-zero construction emissions and operation on 100% renewable energy.
As a small business partner in the Central Valley Stations Joint Venture, HMH is the civil engineer of record and land surveyor of record for the design of the Merced, Fresno, and Bakersfield Stations. HMH performed aerial surveys, supplemental topo surveys, and parcel mapping as the project surveyor.

SR-87/Capitol Expressway Interchange Improvement

in

The SR 87/Capitol Expressway Interchange Improvement project will improve vehicular access between northbound SR 87 and Capitol Expressway, provide high-quality, convenient, and comfortable accommodations for active transportation (bikes and pedestrians) and provide seamless connections between all modes of transportation.
The project will eliminate the existing hook ramps in the northbound direction connecting to Narvaez Avenue and instead replace them with a direct connection to Capitol Expressway. It will reconfigure the Capitol Expressway cross section to provide all the necessary travel lanes, bike facilities (Class IV bikeways), and pedestrian accommodations.
Narvaez Avenue will be right-sized to accommodate all transportation modes as well. The Capitol Expressway intersections will be squared up and upgraded to enhance service to bicycles and pedestrian users while maintaining a high level of service for vehicular traffic and LRT station access from Capitol Expressway will
be reconfigured.
HMH led the Alternative Analysis and preparation of the PSR-PDS to satisfy Caltrans requirements for the PID Phase. HMH is currently leading efforts in the PA&ED Phase in preparation of an EIR and PR.

Foster City Levee Improvements

in

The Foster City levee system, surrounding the majority of the outer bay-front perimeter of the City, is crucial in providing protection from flood hazards and storms. In 2014, the Federal Emergency Management Agency (FEMA) determined that our levee system does not meet minimum requirements for flood protection.
To protect people and property and avoid designating Foster City as a flood zone (which would require expensive flood insurance for most home owners), voters passed Measure P in 2018 to fund the necessary levee improvements.
The Levee Improvements Project will increase the height and width of the levee to improve protection against storm/tide surges, meet sea level rise projections through the year 2050, maintain FEMA accreditation, and make the levee more resistant to earthquakes. The project also includes redevelopment and widening of the Levee/Bay Trail, which will provide the community with an enhanced, more inviting recreation destination.

Montague Expressway Pedestrian Over Crossing

in ,

As part of VTA’s work on the BART expansion to San Jose, the Montague Expressway POC connects the new transit-oriented developments north of Montague Expressway to the new Milpitas BART Station south of the expressway.
Travelers have access to it on one side from in front of the new The Edge apartment building to the second floor of the existing parking garage at the Milpitas Transit Center on the other end. It includes a staircase leading from the ground floor on both sides of Montague Expressway up to the bridge that will cross above Montague. There will also be elevator access at the north end of the bridge, as well as from the western edge of the parking garage at the Milpitas Transit Center.
The team included Biggs Cardosa, DMZ Builders, FMG Architects, Salas O’Brien, Alliance Engineering Consultants, Parikh Consultants, and Artik Art & Architecture.

San Mateo Wastewater Treatment Plant

in

The project includes construction of new wastewater treatment facilities required for the City of San Mateo to meet current and future regulations. The new facilities will be built on City-owned land adjacent to the existing wastewater treatment plant facilities. The project also includes a new administration building for plant staff, a new warehouse, an improved pedestrian path and more. Construction for the new facilities are planned to continue until 2024.
HMH collaborated with Sundt Construction, Inc., Malcolm Drilling Company, Inc., Myers and Sons Construction, Inc., Foundation Constructors, Inc., and Kiewit Infrastructure West Co. on this wastewater project. Our Survey team provided various staking services including: shoring staking, pile staking, yard pipe staking, storm drain staking, sanitary sewer staking, water staking, gridline staking, and interior building staking. In addition, we also provided shoring monitoring, perimeter settlement monitoring, and pile as-builts.

Downtown Pleasanton Parking Lot

in

HMH was engaged by the City of Pleasanton to redesign and expand the City’s downtown parking lot on the former railroad property between Bernal Avenue and Abbie Street. The redesign looked at adding 81 new stalls to the municipal lot, plus other renovations including a retaining wall and site lighting while working with existing constraints that included hazardous materials in existing soil, underground utilities, existing grading, and disruption of downtown operations. The proposed design also maximizes parking, while providing a bicycle and pedestrian concrete walkway.
From a stormwater design perspective, the downtown parking lot stormwater design solution is seen as a signature stormwater project that the City can direct developers to as an example of how to design an efficient and aesthetically pleasing stormwater treatment facility. To achieve this, the project will combine the use of a tradition biotreatment cell and buried Silva cells and use a varied planting pallet to maintain a healthy looking facility year round.
The end result will be an ideal location to supplement downtown parking, create an enjoyable user atmosphere, promote multi-modal and low emission vehicles, offer bike racks and electric vehicle charging, and single element for earth retaining and stormwater treatment.

10th and 11th Street Transit Boarding Islands

in

The 10th and 11th street transit boarding islands project consists of the design for 17 transit boarding islands for VTA buses on 10th Street, 11th Street, San Salvador Street, and San Fernando Street in San Jose, CA.
At the intersections, the project will install concrete islands near the corners that will serve several purposes. First, the concrete islands would slow down turning vehicles, which will create safer crossings for both pedestrians and bicycle users. Second, the concrete islands would help guide vehicle access to the frontage lane and driveways. Third, the concrete islands would provide a location to wait for and board the bus.
The end result is to create safer crossings for pedestrians and bicycle users, increase traffic calming measures, and provide overall ADA improvements.

Silicon Valley Express Lanes (SVEL) Phase 3 & 4

in

In 2008, the VTA Board of Directors approved the Silicon Valley Express Lanes (SVEL) Program which included 4 phases of the implementation of express lanes along SR 237/I-880 and US 101/SR 85. With a forecasted 38% growth in population and a 62% increase in jobs between 2010 and 2040, the program’s long term goal was to manage and relieve congestion along the corridors and tie into San Mateo County’s express lanes. The projects would also provide a more efficient use of existing roadways, a new and reliable travel option, and a new revenue stream for transportation and corridor improvements.
The HMH public works team completed SVEL phase 3 which was a conversion of the existing HOV lanes to Express lanes along US 101 from SR 237 to the San Mateo County line in addition to the SR 85 connectors to US 101 in Mountain View. Phase 4 is expected to be kicked off in late 2019 and will convert the existing HOV lanes along SR 85 from the SR 87 to the US 101 connector in south San Jose. US 101 is an important trade corridor between the Central Valley, Central Coast, and the San Francisco Bay Area while SR 85 is a popular connection for commuters from San Jose, Los Gatos, Cupertino, Saratoga, Campbell, Sunnyvale, Los Altos, and Mountain View. HMH was responsible for the utility coordination and design, the drainage design, and led the development of motorist information plans for the phase 3 final construction document package; similar scope is expected on phase 4.
