Will cross Sand Creek and connect Highway 4 to Heidorn Ranch and Deer Valley Roads in Antioch

On Tuesday, August 8, 2023, a gathering of dignitaries and City of Brentwood staff marked the Sand Creek Road Extension Groundbreaking Ceremony. The long-anticipated extension is a significant milestone in enhancing Eastern Contra Costa County’s transportation infrastructure. While the City had hoped to extend an invitation to the public for the event, due to the project’s location, active construction, and concern for the safety of all participants, it was imperative to limit the total number of attendees.

With an estimated cost of $8.7M, this extension will expand Sand Creek Road at State Route 4 westward, connecting Sand Creek Road to Heidorn Ranch Road. This initiative projects to alleviate traffic congestion on adjacent streets, including Lone Tree Way, Balfour Road and Deer Valley Road. Furthermore, this extension will provide Brentwood residents and emergency personnel, an accelerated and safer route to Kaiser Permanente in Antioch.

It will “provide Brentwood residents with a direct connection to Kaiser hospital and the Innovation Center that includes the recently approved Costco to be located off of Lone Tree Plaza Drive,” Mayor Joel Bryant added.

The project will also include the bridge over the actual Sand Creek. It “was delayed a little bit. The contract was awarded back in April,” Interim Brentwood City Engineer Allen Baquilar shared.

“As we move forward with this project, we must acknowledge the efforts from past City Council and staff, who have diligently paved the way. This road extension will serve as a conduit to a healthier future, providing safety and accessibility for residents traveling to our neighboring city,” emphasized City Manager Tim Ogden.

“With enthusiasm, we observe the commencement of this project. We recognize the community’s understanding and patience exhibited while we addressed challenges and setbacks that emerged during the project’s progression,” Assistant City Manager Darin Gale shared in a press release. “The project’s contractors, Goodfellow Sequoia Joint Venture, have demonstrated their capability to manage the project despite unexpected delays. As the work continues, we are confident in their ability to bring this project to completion, slated for late May 2024.”

“We’re excited to see this project underway and look forward to see it opened, soon,” Ogden added.

Funding source for the road project are from City of Brentwood Development Impact Fees and the Eastern Contra Costa Regional Fee and Financing Authority all provided by new housing and commercial development in the city and East County.

In an email on Thursday, August 10, Contra Costa County District 3 Supervisor Diane Burgis shared the following about the road extension:

“As East County continues to grow, our transportation and infrastructure needs are growing as well. One of the biggest local road improvements is the new Sand Creek Road extension in Brentwood.

The City of Brentwood’s staff and elected officials have been hard at work for years planning the extension, which will lead west from Highway 4 toward Dear Valley Road and connect with other extensions that are already completed.

I had the unique opportunity to speed up the project in February as Chair of the East Contra Costa Regional Fee and Financing Authority (ECCRFFA), when I, along with the four mayors of Brentwood, Antioch, Oakley and Pittsburg, voted unanimously to prioritize funding this shovel-ready extension. I’m proud of our elected officials for working together as a region and putting taxpayer dollars toward a project that will have immediate impacts for public safety and economic development.”

Official Project Description: The project scope includes extension of Sand Creek Road from westerly of the existing terminus at State Route 4 to Heidorn Ranch Road approximately 2,300 linear feet. The improvements include constructing the central 56 feet of roadway (2 – 20-foot roadway and a 16-foot median), streetlights, wet and dry utilities, full-width bridge (4-lane arterial) across Sand Creek, and related work linking State Route 4 to Heidorn Ranch Road.

Take the 1-minute survey to share your input on the future of the Hwy 4 corridor.

The Contra Costa Transportation Authority (CCTA) is developing the State Route 4 (SR-4) Corridor Vision Study in order to develop a long-term, comprehensive transportation plan for SR-4 that addresses congestion, safety, and other mobility concerns in Contra Costa County. SR-4 is the primary east-west highway in the northern portion of Contra Costa County, beginning in Hercules in the west and continuing into San Joaquin County in the east. This work is being done in partnership with the California Department of Transportation (Caltrans).

With this new vision established, CCTA will be able to make forward-thinking investments along SR-4 and the surrounding local roads, railways, waterways, transit systems, and bike and pedestrian connections.

What is a Comprehensive Multimodal Corridor Plan (CMCP)?

This study is a crucial step in CCTA’s efforts to fund transportation infrastructure investments by meeting Senate Bill (SB) 1 Congested Corridor Program requirements for a Comprehensive Multimodal Corridor Plan (CMCP). A CMCP is developed with state, regional, and local partners and is consistent with the Regional Transportation Plan.

A CMCP aims to:

  • Provide holistic guidance for transportation investments.
  • Reduce congestion in highly traveled corridors.
  • Provide more transportation choices for residents, commuters, and visitors while balancing the character of the local community.
  • Create opportunities for neighborhood enhancement projects.

Payment plan for low-income customers, penalty waivers for all bridges, Express Lanes

The Metropolitan Transportation Commission (MTC)’s Bay Area Toll Authority (BATA) today launched a public information campaign to raise travelers’ awareness of two new programs available through the Bay Area FasTrak® customer service center to help people with overdue tolls, penalties and fees get out of debt.

Bay Area FasTrak® now offers a payment plan program for individuals with outstanding toll debt whose household income is no more than 200 percent of the federal poverty level (about $60,000 for a family of four). The Bay Area Toll Payment Plan is open to all who have received toll violations on Bay Area bridges or express lanes. For those who qualify, violation penalties will be waived and any remaining balance of at least $100 can be paid off over time in the payment plan.

This program is intended to provide a way for people with overdue tolls, fees and penalties to get out of debt, and it is not limited to Bay Area residents.

Eligible participants may apply at the program website at bayareatollpaymentplan.org or by mailing or faxing a paper application. Both the website and the paper application are available in English, Spanish, Chinese and Vietnamese.

To ensure those who are income eligible are aware of and have assistance applying for Bay Area Toll Payment Plan, BATA is conducting extensive outreach to social services and housing agencies, as well as to dozens of community-based organizations and other human services programs.

BATA and partner toll agencies last month also began offering full or partial one-time violation penalty waivers that are available to all customers, regardless of income. BATA, the Golden Gate Bridge Highway & Transportation District and MTC’s Bay Area Infrastructure Financing Authority unit will waive all penalties associated with toll violations on their facilities on a one-time basis. The Alameda County Transportation Commission, the San Mateo County Express Lanes Joint Power Authority and the Santa Clara Valley Transportation Authority (VTA) each will waive one penalty per customer for toll violations on their Express Lane facilities.

The one-time penalty waivers will be available to customers through September 2024. To obtain a waiver or to find out if you have overdue toll violations, customers must call the Bay Area FasTrak® Customer Service center at 877-BAY-TOLL (877-229-8655) and pay all outstanding tolls and any DMV fees owed. Eligible customers who choose to enter into a payment plan must make their first payment to receive the penalty waiver.

MTC is the regional transportation planning, financing and coordinating agency for the nine-county San Francisco Bay Area. BATA manages the Bay Area’s FasTrak electronic toll payment system and administers all toll revenue from the Bay Area’s seven state-owned toll bridges.

BRENTWOOD, CA – In partnership with the City of Brentwood, the Contra Costa Transportation Authority (CCTA) is constructing the Mokelumne Trail Bicycle and Pedestrian Overcrossing to provide safe access to cyclists and pedestrians for commuting and recreational travel, reconnecting two sides of the trail that were separated by the expansion of State Route 4.

This overnight closure will facilitate the removing of the temporary structure that was used to support the bridge and will impact State Route 4 in the eastbound direction. CCTA and the California Department of Transportation (Caltrans) have scheduled the closure during the early morning hours in order to minimize impacts to the motoring public.

In order to ensure crew and public safety during the planned construction work, a temporary nighttime freeway closure in the eastbound direction of State Route 4 will occur between Saturday, July 8 and Sunday, July 9, 2023 on the following schedule (weather permitting):

Eastbound Highway 4 will be closed between Lone Tree Way and Sand Creek Road from 9:00 p.m. on Saturday, July 8 until 7:00 a.m. on Sunday, July 9, 2023.

DetoursDetours will be in place to reroute drivers around the closure and are planned as follows:

Eastbound traffic will be directed to exit at Lone Tree Way, go eastbound to Shady Willow Lane, then southbound on Shady Willow Lane to Sand Creek Road, before proceeding westbound on Sand Creek Road to the eastbound State Route 4 on-ramp.

Future Freeway Closures

Additional overnight closures will be needed over the course of the next several weeks (weather dependent) to facilitate ­­­­construction work­­­­­­­­ of the future Mokelumne Trail Bicycle and Pedestrian Overcrossing. Additional information regarding dates and detours will be provided once the schedule is confirmed.

New Poll: Overwhelming support for more police on BART, greater focus on cleanliness, stronger enforcement of rules 

By Leave a Comment

Source: Bay Area Council

San Francisco—BART riders and others who have stopped using the system or reduced their use dramatically say they would return in significant numbers if crime, safety and cleanliness issues are addressed, according to new polling released today by the Bay Area Council. Concerns about crime far outweigh remote work as the reason they are not riding. The findings offer an encouraging path forward for a system that is teetering on the brink of a fiscal cliff as BART ridership hovers at historic lows following the pandemic.

A Bay Area Council analysis of the poll findings suggests that by taking a much stronger and swifter approach to crime, safety and cleanliness, BART could see up to 300,000 more trips over the course of the workweek, pushing ridership above 50% of pre-pandemic levels.

Key Findings 

  • 79% say they feel more comfortable riding BART when there is a uniformed police officer or security present
  • 73% say BART should prioritize adding more uniformed police on trains and in stations
  • 62% say BART should improve fare gates to prevent fare evaders; 66% want fare gates to fully enclose station entrances
  • 79% say BART should eject people from the system that violate the passenger code of conduct, which prohibits drugs, smoking, drinking and other illegal or unacceptable behavior
  • 65% say BART should focus on core operations and leave social service issues to other public agencies
  • 90% put high priority on more frequent cleaning
  • 74% feel things in the Bay Area have gotten pretty seriously off on the wrong track

Riders and residents overall are crystal clear about what the main barriers are for them to returning to BART. Among all respondents, including those that never or rarely ride BART, 78% said they would ride BART more often if it was significantly cleaner and safer. This number is particularly striking when compared to the far fewer 46% of respondents who stated they would ride BART more often if they had to commute to work or school more frequently.

There is similar enthusiasm for returning to BART among the 37% of respondents who were regular BART riders before the pandemic but have since dramatically curtailed their use of the system or dropped off completely. These riders may represent BART’s best opportunity to bring more riders back to the system more regularly, with 59% saying they would ride BART a lot more often with safety and cleanliness improvements. But they also generally harbor much stronger levels of dissatisfaction with the system than others who are not BART riders.

“There can be no higher priority for BART and the future survival of the system than to direct every ounce of energy and resources into making the system safer and cleaner,” said Jim Wunderman, President and CEO of the Bay Area Council, which was instrumental in the creation of BART in the 1950s and has long been a champion for the system. “We specifically call on BART to immediately and significantly increase police and security personnel on trains, vigorously enforce the rider code of conduct, and install new fare gates within a year. BART must treat this like a crisis, because it is a crisis. BART is the mass transit backbone of our region and there’s too much at stake for BART and our region not to be more aggressive in addressing the reasons legions of riders are staying away. BART deserves credit for recent moves to increase police presence and ramp up cleaning, but riders and others are saying they must do more and they must do it now.”

See the BART poll findings>> 

Read the full BART poll questionnaire>> 

The concerns about safety and cleanliness are reflected in overall sour views of the system, with 49% giving BART an unfavorable rating compared to 30% for SF MUNI, 23% for AC Transit and 15% for Caltrain. The poll by EMC Research surveyed 1,000 residents in Alameda, Contra Costa, San Francisco and northern San Mateo counties encompassing BART’s service area. The poll has a margin of error of +/-3.1 percentage points.

Having a more visible police presence across the system is critical to bringing riders back. A vast majority of all those surveyed say they want more police officers on trains and in stations, they want more frequent cleaning of train cars and stations, and they want BART to strictly enforce an existing code of rider conduct which outlaws gate-hopping fare cheats, drinking and smoking, drug use and other illegal and dangerous behaviors.

These attitudes shouldn’t come as a big surprise. According to the poll, 53% of residents know of someone who has been a victim of crime on BART, 46% say they have witnessed crime on BART, and 18% say they personally have been a victim on crime on BART. Meanwhile, 44% of BART riders said they have never or rarely seen a police officer.

Overnight Hwy 4 (bypass) closure for Mokelumne Trail overcrossing postponed until May 12 & 13

Between Lone Tree Way and Sand Creek Road

The overnight closure of State Route 4 between Lone Tree Way and Sand Creek Road in Brentwood originally planned for Friday, May 5 through Saturday, May 6, 2023 has been postponed one week to Friday, May 12 through Saturday, May 13, 2023.

In partnership with the City of Brentwood, the Contra Costa Transportation Authority (CCTA) is constructing the Mokelumne Trail Bicycle and Pedestrian Overcrossing to provide safe access to cyclists and pedestrians for commuting and recreational travel, reconnecting two sides of the trail that were separated by the expansion of State Route 4.

When completed, the overcrossing will provide access to the future East County Intermodal Transit Center and BART Station in Brentwood, as well. It is part of the larger Mokelumne Coast to Crest Trail which also includes the Delta de Anza Regional Trail that runs through Antioch and Oakley,  that will, when completed, connect six counties across California from the East Bay to the Sierra Nevada Mountains.

The overnight closure will facilitate final adjustments to the falsework as part of the construction work installing the pedestrian and bicyclist crossing over State Route 4. This closure will impact State Route 4 in both the Eastbound and Westbound directions. CCTA and the California Department of Transportation (Caltrans) have scheduled the closure during the early morning hours in order to minimize impacts to the motoring public.

In order to ensure crew and public safety during the planned construction work, a temporary nighttime freeway closure in both directions of State Route 4 will occur in both Eastbound and Westbound lanes of Highway 4 from midnight on Friday, May 12 until 6:00am on Saturday, May 13, 2023 (weather permitting).

Detours
Detours will be in place to reroute drivers around the closure and are planned as follows: Eastbound traffic will be directed to exit at Lone Tree Way, go eastbound to Shady Willow Lane, then southbound on Shady Willow Lane to Sand Creek Road, before proceeding westbound on Sand Creek Road to the eastbound State Route 4 on-ramp.

Westbound drivers having to detour will exit on Sand Creek Road and go eastbound on Sand Creek Road to Shady Willow Lane, then northbound on Shady Willow Lane to Lone Tree Way, and proceed westbound on Lone Tree Way to the westbound State Route 4 on-ramp.

Future Freeway Closures

Additional overnight closures will be needed over the course of the next eight weeks (weather dependent) to facilitate concrete pours for the stem and soffit and deck of the future Mokelumne Trail Bicycle and Pedestrian Overcrossing. Additional information regarding dates and detours will be provided once the schedule is confirmed. This project is anticipated to be complete in late summer or early fall of 2023.
