Over the next three months, Walnut Creek has closures at four of its most-used public places at once: the Civic Park playground, the Ygnacio Valley Library, the Heather Farm aquatic site and the Iron Horse Trail's Treat Boulevard overcrossing. In nearly every case, the city or county kept a nearby alternative open and planned the timing so the old facility keeps working until the new one is ready.
The table shows how each one pairs up. The rest of this post covers the dates, and the two spots where there's no stand-in.
| What's closed | When | What stays open instead |
|---|---|---|
| Civic Park Playground | Right after Halloween, about 6 to 7 weeks | Pop-In Play at Park Place, plus the rest of Civic Park |
| Ygnacio Valley Library, 2661 Oak Grove Road | Sept. 9, 2026 to around May 31, 2027 | Walnut Creek Library on North Broadway, now open 56 hours a week |
| Heather Farm aquatic and community center site | Construction through 2027 | Clarke Memorial Swim Center, dog park, Gardens at Heather Farm |
| Robert I. Schroder overcrossing on the Iron Horse Trail | Oct. 5 to Dec. 31, overnight only | Daytime trail use |
Civic Park Gets Busier While Its Playground Is Fenced
Civic Park, at 1365 Civic Drive, is the clearest example of the city sequencing a closure around the calendar. Trunk or Treat comes first. The seventh annual event is Friday, October 23, from 3 to 6 p.m. A low-sensory hour runs from 3 to 4 p.m., and general activities go from 4 to 6. After that, the City of Walnut Creek's October recreation newsletter says the playground redesign is "scheduled to start right after Halloween," with "a 6-7 week closure."
A 6-to-7-week window that starts in early November runs well past November 20, 2026. That's the date of the Holiday Tree Lighting Ceremony in Civic Park and opening day for Walnut Creek on Ice, which runs through January 18, 2027. So on the park's two busiest holiday nights, the playground will still be under construction. Skating and the ice slide each cost $20 per 90-minute session. The combo ticket is $20 on non-holiday weekdays and $30 on weekends and holidays, and the event is cashless.
The city has named an alternative for younger kids. Its newsletter points families to Pop-In Play, held Monday through Thursday from 9:30 to 11:30 a.m. at Park Place, 1365 Civic Drive, with both indoor and outdoor play space.
Why the playground is being replaced now
The structures are old. A January 20, 2026 City Council agenda report says the original Civic Park playground equipment went in in 1997. It got an ADA-driven renovation in 2015 and has since been "showing signs of corrosion, and failing equipment." The council unanimously approved a $572,902 agreement with Playcore Wisconsin, Inc., which does business as GameTime. That figure is $522,902 for materials and installation plus a contingency of up to $50,000.
The design reflects about 600 survey responses, which the city collected by promoting the survey at the Downtown Locust Festival, at pop-up events and on its website. The city also skipped a standard bid process by "piggybacking" on an existing, nationally bid agreement held by another public agency. Staff estimated that saved about three months.
The schedule has already moved once. A May 2026 council priorities report expected construction in the third quarter and completion by September. The later newsletter moved the start to after Halloween and gives no reopening date. Until the city posts one, the 6-to-7-week estimate is the only timing available.
The Library Swap Was Planned Before the Branch Closed
The Ygnacio Valley Library stand-in was set up first, and it shows the city planning ahead most clearly. According to the Walnut Creek Record, the branch at 2661 Oak Grove Road closed September 9 and is expected to reopen around May 31, 2027. Crews are installing an all-electric HVAC system and a new roof and reworking the electrical and lighting systems. The project is paid for with Measure X funds plus county library reserves.
The extra capacity came two months early. Starting July 1, the city funded four more open hours a week at the main Walnut Creek Library on North Broadway, bringing it from 52 to 56 hours. Uncollected holds from Ygnacio Valley were moved there. Patrons can also use any open Contra Costa County Library branch, including Clayton, Concord and Pleasant Hill.
The closure also changed where the city put an election drop box. With the branch closed, the city installed a new official ballot drop box at Shadelands Art Center, 111 N. Wiget Lane. Drop boxes opened October 5 and accept ballots until 8 p.m. on Election Day, November 3. The city's other official boxes are at City Hall, 1666 N. Main Street, which has two, and at Grace Presbyterian Church, 2100 Tice Valley Blvd.
Heather Farm Keeps the Old Pool Running Until the New One Is Ready
Heather Farm is the biggest project on this list and the longest-running example of keeping the old facility open during the build. The Bay Area Telegraph puts the aquatic and community center rebuild at more than $75 million. Most of the money comes from Measure O, the ten-year half-cent sales tax voters approved in 2022, with added funding from the General Fund Facilities Reserve and bond proceeds.
The Telegraph also reported that Clarke Memorial Swim Center will stay open during construction and won't be torn down until the new aquatic complex is ready. Swim programs don't move anywhere else in the meantime. Larkey is listed as "Closed (Team use only)," and Clarke is listed as open for regular programming.
Here's where the build stands. A city construction update from October 6 shows utilities and sub-drainage in place at the competition pool site, crews getting ready for gunite and vertical construction under way on the building. The Telegraph reports that earlier schedules aimed for a summer 2027 grand opening, but the city's construction-impact page now says work could run through the end of 2027.
Outside the fencing, these parts of the park are open:
- Sports Fields 1 and 2 were converted to synthetic turf, also with Measure O money, and reopened in December 2025.
- The off-leash dog park at the north end is open 8 a.m. to dusk, except Thursdays, when it opens at noon.
- The Gardens at Heather Farm is free and generally open seven days a week, though it closes for private events.
- Picnic sites 2, 3, 4, 5 and 12 are listed as closed for construction.
Construction usually runs 7 a.m. to 5 p.m., with weekend work allowed when needed. The city refilled the cement pond in late 2025, but it says nearby construction still limits access to the pond.
After the new complex opens, the city will turn to the roughly three-acre Clarke site. Ideas discussed 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.
On the Iron Horse Trail, the Closures Are Overnight
The trail closures are limited by hour instead of by location. According to the East Bay Regional Park District, the Robert I. Schroder Pedestrian Bridge overcrossing is closed for county repairs from October 5 through December 31, 2026. Work runs overnight, 9 p.m. to 5 a.m., Sunday through Thursday. Drivers on Treat Boulevard may see delays of up to 10 minutes and occasional lane closures.
A separate closure ends today. The segment between Mt. Diablo Boulevard and Civic Park was closed October 5 through 12 while PG&E trimmed and removed vegetation near power lines.
Where There's No Stand-In
There are two gaps. The first is the Civic Park reopening date. "Right after Halloween" plus 6 to 7 weeks is a range, and the city has published no firm date.
The second is Walden Park. The city surveyed residents about playground designs for Civic Park and Walden Park together in June 2025. An earlier plan had both playgrounds starting construction in the first quarter of 2026. The city's May 2026 progress report says funding limits cut the scope to Civic Park equipment only "at this time," and it gives no new date for Walden. The city maintains 16 playgrounds, so one funded replacement this year leaves the rest on the Municipal Maintenance Master Plan's long-term schedule.
Volunteer Dates in the Open Space
The Walnut Creek Open Space Foundation has several dates on its October calendar:
- Bayberry Pond habitat restoration: Tuesdays, October 13, 20 and 27, 9 a.m. to noon. Volunteers meet at the end of Bayberry Drive and work in North Lime Ridge.
- Wildlife habitat restoration: Wednesdays, October 14, 21 and 28, 9 to 11 a.m. Volunteers meet at the end of Rock Oak Road, also in North Lime Ridge.
- Scorpion Hike: Saturday, October 24, 7:30 to 9:30 p.m., about two miles.
The restoration sessions are free. Put together, the city calendar from now through the end of the year runs like this. Trunk or Treat is October 23. The playground fences go up after Halloween. Ballots are due November 3. Civic Park's tree lighting and ice rink both open November 20, while the playground is still under construction. The overnight bridge work finishes December 31.
Projects like Heather Farm, the Ygnacio Valley Library and the Civic Park playground shape what a part of town feels like over the next couple of years.
