Midnight to 6:00 am for Mokelumne Trail overcrossing

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.  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.

Overnight Freeway Closure of State Route 4 between Lone Tree Way and Sand Creek Road
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 between Friday, May 5, 2023 and Saturday, May 6, 2023 on the following schedule (weather permitting):
Eastbound and Westbound Highway 4 will be closed from midnight on Friday, May 5 until 6:00am on Saturday, May 6, 2023. 

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.

To open March 29 from Balancing Rock to Riggs Canyon on Mount Diablo

By Laura Kindsvater, Communications Manager, Save Mount Diablo 

On March 29, Save Mount Diablo will officially open the Knobcone Point to Riggs Canyon trail connection. This section of trail winds through the upper 560 acres of Mount Diablo’s Curry Canyon Ranch, through one of Mount Diablo’s wildest areas. It travels from Balancing Rock and Knobcone Point, to Cave Point, to Windy Point and Riggs Canyon.

Although the trail was once available to the public ranging all over the mountain before proliferation of cattle fencing, it’s been nearly a hundred years since it was legal.

The 1.25-mile-long trail will considerably expand the amount of open space available to explore on Mount Diablo’s southern hills. It will effectively fully connect Rock City and Mount Diablo to Riggs Canyon, Morgan Territory, and Los Vaqueros via publicly accessible trails.

Curry Canyon is the final missing major canyon entrance to Mount Diablo. Curry Canyon Ranch has over nine miles of fire roads, most of which will continue to be closed for now, while Save Mount Diablo works with California State Parks to transfer much of the property to the park.

Currently Mount Diablo State Park visitors must climb in and out of four canyons from Rock City to Riggs Canyon—going forward, they can follow a ridgeline with spectacular views.

Right now, state park staff must leave the state park to reach Riggs Canyon. Opening the ridgeline fire road on Save Mount Diablo’s property will solve this access and management issue.

In preparation for the grand opening, Save Mount Diablo’s staff and volunteers have been installing infrastructure, including access gates and informational signage.

They have also been removing dead material to minimize fire risk in the area. The removal of dead and scorched plants in this area will encourage new growth of native and endemic wildflowers and chaparral plants this spring.

This project has been a decade in the making, in the works since Save Mount Diablo acquired the 1,080-acre Curry Canyon Ranch property in 2013.

“Thanks to our terrific supporters, staff, partners, and volunteers, like our Trail Dogs, Save Mount Diablo has created and opened a number of public trails the last two years. Last year, we created and opened over four miles of trails at our new Mangini Ranch Educational Preserve. This year, we will finish and open an important 1.25 +/- mile trail on Save Mount Diablo’s Curry Canyon Ranch that will allow the public to hike from Knobcone Point at Mount Diablo State Park, through the upper portions of our spectacular Curry Canyon Ranch, to Riggs Canyon at the state park. All these trails we have built are portals that allow the public to enter nature and be transformed for the better,” said Ted Clement, Save Mount Diablo Executive Director.

As part of its goal of getting more people into nature, Save Mount Diablo has been opening more land to the public and creating new trails over the years. In 2022, Save Mount Diablo opened several miles of trails at its Mangini Ranch Educational Preserve in Concord for people to enjoy.

Now the highly anticipated Knobcone Point trail connection will further open up opportunities to enjoy Mount Diablo’s majestic views and wilderness—recreationalists will experience a rarely seen part of the mountain.

“This trail is the major recreational puzzle piece in the Mount Diablo area, allowing park users to connect the mountain to Morgan Territory and beyond to Los Vaqueros, furthering their adventure into this extraordinary place,” said Sean Burke, Save Mount Diablo Land Programs Director.

Traveling along this newly opened trail, visitors will be immersed in the knobcone pine forests after which the area is named and stunning sandstone rock formations. They may see golden eagles and songbirds fly overhead.

This trail will open up a rarely traveled area; it will give hikers an opportunity to explore and experience the solitude of one of the extraordinary parts of Mount Diablo.

A trail opening ceremony will take place on the property at the Knobcone Point gate near Balancing Rock at 11:00 AM on March 29, weather permitting. We invite the public to hike in and join us. If you’d like to come, meet at Curry Point in Mount Diablo State Park on South Gate Road at 9:30 AM. There is a park entrance fee of $10, and parking at Curry Point is limited. The hike from Curry Point to the ceremony is a little over two miles.

After the ceremony, staff will lead a hike to the Riggs Canyon gate. The hike from the Knobcone Point gate to the Riggs Canyon gate is 1.25 miles.

In the event of heavy rain, the trail will still be opened to the public on March 29, but we will cancel the trail opening ceremony.

It is with great pride and excitement that Save Mount Diablo will open this trail connection and share the beauty of Knobcone Point, Cave Point, and Riggs Canyon with all who visit.

The East Bay Regional Park District is looking to hire over 50 new lifeguards for the 2023 swim season at its 12 East Bay swim facilities, which include lakes, lagoons, and swimming pools. All new lifeguard positions are seasonal, full-time positions from May through September. Anyone ages 16 and over before April 22, 2023, are encouraged to apply. Starting pay is $20.78 per hour. Applications will be accepted through March 27, 2023.

There are six lifeguard testing dates scheduled in March. Participants will be asked to swim 550 yards in under 10 minutes, carry a rescue board 50 feet, retrieve three dive rings under four to seven feet of water, tread water for two minutes using only their legs, and retrieve a 10-pound brick from underwater. There will also be a short informal interview after successful completion of the swim test on the same day.

Testing Schedule:

•    Saturday, March 11, at Buchanan Pool, Pittsburg

•    Sunday, March 12, at Granada High School Pool, Livermore

•    Saturday, March 18, at San Leandro High School Pool, San Leandro

•    Sunday, March 19, at Granada High School Pool, Livermore

•    Saturday, March 25, at Buchanan Pool, Pittsburg

•    Sunday, March 26, at Castro Valley High School Pool, Castro Valley

Participants who pass the tests will be invited to the Park District’s Lifeguard Academy beginning Saturday April 22, 2023, where they will receive paid training and certification in open water lifeguarding. The Lifeguard Academy takes place over five consecutive weekends in April and May, with the swim season beginning in late May for most facilities.

“Working as a lifeguard is one of the few ways a young adult can give back to their community and learn about public service,” said East Bay Regional Park District Aquatics Manager Pete DeQuincy. “Promoting water safety and educating park visitors on how to safely recreate in, on, and around water is paramount in what a lifeguard does.”

Lifeguards can work at any of the Park District’s swim facilities in various cities in Alameda and Contra Costa counties, such as Antioch, Concord, Livermore, Hayward, Castro Valley, Oakland, Alameda, and Berkeley.
