On Friday, October 23, Civic Park hosts Trunk or Treat. That night, a drone show over the Lesher Center marks the start of the Diwali celebration. About a week later the playground in the same park closes for a rebuild. Three weeks after that, the ice rink opens a few steps away. Downtown has a lot of construction fencing this season, and a lot of holiday events are going ahead right next to it.

Most of the fencing in Walnut Creek this fall is repair or replacement work, and nearly all of it has a published end date. Those dates fall into two groups. The downtown repairs are scheduled to finish around the holidays. The neighborhood projects, including a branch library, the Heather Farm pools and a foothill trail, run well into 2027. The schedule for each one decides whether you can wait it out or need a different routine for a year.

The Two Clocks, Side by Side

The top two rows are the short clock. Both are downtown or close to it, and both are scheduled to finish by the end of the calendar year. The bottom three are the long clock.

Civic Park Closes and Opens in the Same Six Weeks

The city's October recreation newsletter says the Civic Park Playground redesign is "scheduled to start right after Halloween" and to keep the playground closed for six to seven weeks. If that holds, the playground should reopen around mid-December. An earlier city schedule had the playground upgrades finished by September, so the post-Halloween start is the current plan. The newsletter promises "fun new amenities for all ages" and includes a rendering, but it doesn't list the equipment.

While the playground is closed, the city suggests its Pop-In Play space at Park Place, 1365 Civic Drive. It runs Monday through Thursday from 9:30 to 11:30 a.m., with indoor and outdoor areas.

The Holiday Tree Lighting is set for Friday, November 20, from 5:30 to 6:30 p.m. at Civic Park, 1375 Civic Drive. It's free, with carolers, cocoa and Frosty. Walnut Creek on Ice opens the same day at 1365 Civic Drive and runs through January 18, 2027. In its October 13 announcement, the Walnut Creek Business Association calls it the Bay Area's only outdoor ice rink and ice slide. This is its 21st season, with the 90-foot Frosty's Summit Ice Slide, private fire pits and Wednesday morning Littles Skates. Kathy Hemmenway, the association's executive director, said in the same release, "After 21 years, we've seen kids grow up on this ice and come back with families of their own."

For about four weeks, then, the park will have a fenced playground and an open ice rink at the same time. The city hasn't said how the two work areas will be laid out, so check the entrances before you bring a stroller.

The trail next to the park also had work this month. PG&E scheduled about a week of tree trimming and removal on the Iron Horse Regional Trail between Civic Park and Mt. Diablo Boulevard, starting the week of October 5, and closed sections of the trail while crews worked.

The Bridge That Ends With the Year

South along the same trail, the Robert I. Schroder Pedestrian Bridge over Treat Boulevard has been closed since Monday, October 5. The East Bay Regional Park District lists the closure through Thursday, December 31, "barring unforeseen circumstances." Crews work from 9 p.m. to 5 a.m., Sunday through Thursday. Drivers should expect 10-minute delays and occasional lane closures on Treat Boulevard.

The work is routine maintenance. Contra Costa News reported that the county's scope covers new bearing pads, paint repairs, a deck treatment, and new sidewalk and curb. Trail users are detoured to the street crossing on Treat Boulevard, following signs. The county also plans about four overnight closures of Treat Boulevard itself, with a vehicle detour of roughly five miles. Those dates are still to be posted.

For anyone who walks or rides the Iron Horse, the change is a signaled street crossing in place of a bridge until the new year. For anyone driving Treat late at night, check the county notices for those overnight closure dates.

The Long Clock: Three Projects That Outlast the Holidays

The other three closures last much longer. For these, it makes more sense to change your routine than to wait.

• Ygnacio Valley Library closed on September 9 for a new all-electric heating and cooling system, a new roof, electrical upgrades and new lighting. The city expects it to stay closed until about May 2027. The book drop and parking lot are closed as well. Holds moved to the Walnut Creek Library at 1644 N. Broadway, and you can return books at the Walnut Creek, Clayton, Concord and Pleasant Hill branches.
• Stage Road Trail in Castle Rock and Diablo Foothills is closed from October 2026 to October 2027 for construction projects the park district hasn't named. The main staging area at 1700 Castle Rock Road will also close at times. The Diablo Foothills park page still lists the Orchard, Castle Rock Road and Livorna access points. The district separately expects the Castle Rock Pool Complex to reopen for the 2027 swim season.
• Heather Farm is in the middle of building its new Aquatic and Community Center. More on that below.

Heather Farm is the biggest of the three and the clearest example of how long these schedules can run. The new center will include a 50-meter competition pool, a recreation pool, multipurpose rooms, classrooms and terraces. In August, the Bay Area Telegraph described the site as "totally torn up." It reported that earlier schedules aimed for a summer 2027 grand opening, but the city now warns that work could run through the end of that year. Picnic areas 2, 3, 4 and 5 are closed. In July, Claycord reported that a city bid document allowed completion in "late 2027 or early 2028." The city's construction page gives the end of 2027.

Swimmers keep their pool in the meantime. Clarke Memorial Swim Center stays open during construction, and the Telegraph reports it won't be torn down until the new complex is ready. Part of the park has already reopened. The Telegraph reports that Sports Fields 1 and 2 were converted to synthetic turf with Measure O funding and reopened in December 2025. The Nature Lake expansion is also finished.

What Fits Inside the Short Clock

Most of this season's events take place downtown, in the area where the repairs are scheduled to finish first. Here is what's on the calendar from late October to the end of the year:

1. Friday, Oct. 23: Trunk or Treat returns to Civic Park. That evening, a free drone light show runs from 9:15 to 9:30 p.m., with a viewing area on Locust Street in front of the Lesher Center for the Arts.
2. Saturday, Oct. 24: The free, all-ages Diwali Street Fair runs from noon to 5 p.m. at 1601 Civic Drive, with performances, food vendors and an artisan market.
3. Oct. 25 to Nov. 15: Center REP stages "Dracula: A Comedy of Terrors" at the Lesher Center.
4. Tuesday, Oct. 27: Lindsay Wildlife Experience holds Howl-ooo-ween from 3 to 8 p.m., with animal encounters, crafts and games.
5. Sunday, Nov. 15: Shadelands FallFest at Shadelands SportsMall, 11 a.m. to 2 p.m.
6. Friday, Nov. 20: The tree lighting and the opening of Walnut Creek on Ice, both at Civic Park.
7. Dec. 9 to 23: "A Christmas Carol" at the Lesher Center.

Lindsay Wildlife has more planned for December: Junior Zookeeper "Keeper for a Day" on December 6, Tiny Tuesday: Winter Wildlife on December 8, and Wild Winter Camp starting December 28. If the schedules hold, the playground and the Schroder Bridge should both reopen during the ice rink season.

When the Long Clock Runs Out

The long-term projects lead to more planning. Once the new Heather Farm complex opens, the city will decide what to do with the roughly three-acre Clarke Swim Center site. The Telegraph reports that ideas so far include more green space, pickleball or bocce courts, a basketball court and an amphitheater. That planning is a separate process, and no design has been chosen.

There's also a shorter deadline. The city's Walnut Creek 2050 online workshop and questionnaire are collecting input on where future housing, jobs, recreation and gathering places should go. Feedback closes Sunday, October 25.
