City of West Sacramento, Grand Gateway and Washington District Infrastructure Project Dedication

The City of West Sacramento saw the completion and dedication of the Grand Gateway and Washington District Infrastructure Project in West Sacramento on March 19th. This ambitious and necessary infrastructure project is part of the City’s initiative to inspire growth, improve building and increase permits, attract investors, support walkable, green, and affordable housing, and further the connectivity of travelers on either side of the river. The upgrades have been in progress since 2015 as part of a state-funded program backed by Congresswoman Doris Matsui.
A unique feature of this project is its incorporation of art and poetry into the design to beautify public
spaces while improving public works. The crowd gathered to celebrate the dedication and had a chance to ride JUMP bikes along the project site to the final destination on E street. There they were able to hear and see a poem written and presented by former Sacramento poet laureate and Sacramento City College English Professor Jeff Knorr. The dedication ceremony included presentations by various representatives of the project development team from the City of West Sacramento, including Mayor Christopher Cabaldon, who called the project “A grand entrance to our City and our future.”
Ghirardelli Associate Thanh Dickerson was a vital part of the project’s construction management and delivery.
Project highlights include:

  • Upgrades to 2,000 feet of water, 6,000 feet of sewer, 3,200 feet of storm drain lines along with significant transportation improvements.
  • The cleanup of the Grand Gateway site at 815 West Capitol Ave. and extension of 7th Street to Tower Bridge Gateway, added a new signalized intersection.
  • A multi-modal transit station, 2.5 miles of enhanced bicycle lanes, 50 streetlights and 43,000 square feet of widened sidewalk.

Exide Residential Cleanup Project Management Services

Ghirardelli was awarded a two-year contract with a one-year option to extend with the Department of Toxic Substances Control (DTSC) to support the Exide Division (Project Team) during implementation of the Removal Action Plan.
DTSC is implementing a Cleanup Plan focused on sensitive use properties within a Preliminary Investigation Area (PIA), which is the area within the 1.7-mile radius of the former facility. The Cleanup Plan includes, among other related removal action activities, excavation of lead contaminated soil from approximately 2,500 sensitive use properties in the PIA. DTSC selects properties for cleanup by using previously collected soil sample results to determine whether a sampled property meets the prioritization criteria set forth in the Cleanup Plan. DTSC has retained National Engineering and Consulting Group (NEC) to conduct work at 415 properties, and Parsons Environment and Infrastructure Group (Parsons) will conduct work at 1,610 properties.
Ghirardelli will consult with the Exide Project Team to develop management systems and strategies for tracking cleanup work progress (including contaminated soil excavation and disposal, property restoration, and compliance with applicable plans, policies, and other requirements); and will assist the Exide Project Team with day to day oversight and review of NEC and Parsons’ deliverables to help ensure success in DTSC’s implementation of its Cleanup Plan and Mitigation Monitoring and Reporting Program.

San Francisco Water Emergency Transportation Authority (WETA) Richmond Ferry Terminal Grand Opening

The excitement on the Richmond waterfront on January 10th was palpable, as hundreds gathered to celebrate the launch of the brand new ferry service to downtown San Francisco.
The first ferry left at 6:10 a.m. from the new $20 million terminal located next to The Craneway Pavilion at 1414 Harbour Way South. The ferry continued on to the San Francisco Ferry Building, a roughly 35-minute trip that was depicted in a flurry of photographs and video posted to social media. Richmond Mayor Tom Butt, credited as one of the ferry terminal’s champions, filmed what he called a smooth ride on a beautiful morning.
“This is the first time in 61 years that we have sustainable ferry service back in Richmond,” Contra Costa County Supervisor John Gioia said. “It’s really a great day.”
To start, San Francisco Bay Ferry Service is making four runs from Richmond to San Francisco during morning commute hours, and four runs from San Francisco to Richmond in the evening commute hours. High demand could expand service in the future, officials said.
The ferries are launching from a terminal that features a new ADAcompliant gangway and ramping system, passenger shelter, 362 spaces of free parking and a new ADAcompliant kayak launch ramp.
Elected officials lauded the ferry as one of many solutions needed to address excessive traffic along the Interstate Highway 80 corridor.
Assembly member Buffy Wicks said it recently took her 90 minutes during rush hour to drive from South Berkeley to Hercules.
“When people are out on the water, they are not on Interstate 80,” Wicks said. “We need an all-the-above approach when it comes to our transportation needs.”
The ferry terminal project was funded through various sources, including state Proposition 1B, U.S. Department of Transportation funds, and $12 million in Regional Measure 2 bridge toll revenue. Operating costs for the next 10 years will come from both fare revenue as well as Contra Costa County Measure J funds.
So far, reviews of the new ferry service have been positive. Cesar Zepeda, president of the Hilltop District Neighborhood Council, called his ride clean, safe, and relaxing. Others echoed Mayor Butt’s sentiment, saying their ferry trip provided a front row seat to a stunning sunrise.

GAI Awarded Construction Management Services for Slope Stabilization Project

Ghirardelli Associates was selected by OCTA to provide construction management services for the Los Angeles – San Diego – San Luis Obispo Rail Corridor (LOSSAN) Right of Way (ROW) Slope Stabilization Project.
The scope of work requires working within an active rail corridor and brings a unique set of challenges that require a combination of both methodical planning and the ability to adapt to the types of unforeseen conflicts typical of underground construction.
The LOSSAN rail corridor serves Metrolink, Amtrak, as well as Union Pacific and BNSF freight trains and is identified as the second most heavily traveled intercity passenger rail corridor in the nation. With combined annual ridership in excess of 7 million passengers, and the transport of countless tons of cargo, the maintenance and operation of this corridor is a key element in the functionality of the region’s overall transit system. The LOSSAN Slope Stabilization project is intended to repair previous erosion damage and to prevent future issues via a combination of enhanced drainage facilities and slope armoring.
Key Project Elements include:

  • Selective Slope Grading and Geosynthetic Armor Installation
  • Install Shotcrete along Slopes Close to Tracks
  • Railway Coordination
  • Utility Protection and Carrier Coordination
  • Underdrain Construction

GAI Awarded Washington District Sustainable Community Infrastructure Project

Due to its age and the demands of urban development, additional strain has been revealed in the Washington District’s infrastructure, including inadequate water, sewer, storm drain, and transportation backbones. Substantial utility and street improvements are needed in order to accommodate existing and alternative modes of travel in the neighborhood.
Ghirardelli Associates was selected by the City of West Sacramento to provide construction management services for the District project to correct infrastructure deficiencies. Sidewalks will be made more accessible, bike lanes added, and several roadways will be re-evaluated for more efficient multi-modal traffic flow. Large street canopy trees will be preserved, and new street trees will be planted. The project will also be designed to handle a future streetcar extension that will circulate along the Third Street corridor, jogging west to 5th Street and then east on C Street and over the new bridge to connect to Railyards Boulevard in Sacramento. Water, sewer, and storm lines will be upsized and replaced, and overhead utilities will be placed underground where feasible.
Construction is currently underway and is expected to be completed by January 2019. The funding sources will be a $4.2 million climate investment fund grant awarded by the California Strategic Growth Council for Infrastructure, the state Active Transportation Program (ATP), and local match by the city of West Sacramento’s community investment fund and sewer impact fees. The estimated design and construction cost is $5.7 million.

GAI Awarded Bay Area Rapid Transit (BART) On-Call Construction Management Contract

On June 14, 2018 at 12:50pm, the Bay Area Rapid Transit (BART) Board unanimously voted on awarding eight companies each $25 million On-Call Construction Management Contracts. The Ghirardelli Associate’s team will be one of the eight teams awarded to deliver projects for the $3.5 billion General Obligation Bond—Measure RR—over the next five years. This work will help rebuild and upgrade the backbone of the Bay Area transportation system. BART originally carried 100,000 people per week, but now serves roughly 440,000 riders per weekday, and ridership is expected to increase 75% by 2040. The 44-year-old system is showing its age. Reinvestment is necessary to keep BART safe and reliable, to reduce crowding, and to keep cars off the road. Ghirardelli Associates will be there to help BART rebuild their aging system.
Funds must be spent on specific infrastructure programs:

  • Replace 90 miles of rail that has been severely worn down over 44 years of use
  • Repair tunnel walls damaged by water
  • Modernize BART’s 1960s-era electrical infrastructure
  • Enhance BART’s ability to withstand an earthquake
  • Prevent breakdowns and delays by replacing antiquated train control systems
