Centennial Local Happenings: September 19–23, 2026 |
Fall cleanup, a neighborhood car show, one of the library’s biggest book sales, free financial education and an opportunity to follow Centennial’s growth |

The calendar says fall officially arrives this week, and Centennial seems ready for the handoff. 🍂 From practical yard cleanup to books, cars and community decision-making, September 19–23 offers several ways to spend time close to home while staying connected to what is happening around Centennial, Colorado. Turn Those Fall Branches Into Free MulchIf autumn yard work has already produced a suspiciously impressive pile of branches, Centennial’s Free Chipping and Mulch Event arrives Saturday, September 19. From 8 a.m. to noon, Centennial residents can bring eligible tree limbs, branches, firewood, logs under 10 inches in diameter and dead shrubs to the Centennial Public Works Facility, 7272 S. Eagle Street, for free recycling. Proof of Centennial residency is required, and unloading is self-service.

Sunday bag day at the library is underrated. Go later in the day if you want less crowds.
Thank you for including details about event timing and location. Makes it much easier to plan a weekend with kids.
Hope the mulch isn’t all gone quick. Last year when I got there around 12:30 p.m., it was pretty picked over.
This is the kind of stuff that makes living here great. Sounds cheesy but small community things add up.
I love Koelbel but always forget about the sale until it’s over. Appreciate the reminder!
Honestly, self-unloading at the Public Works Facility is no joke if you bring big branches. Bring gloves!
Is the free mulch event yearly? I missed out last time and would like to plan ahead.
Great question! Centennial typically offers the free chipping and mulch event annually, usually in early fall, keep an eye on the City calendar for future dates.
Thanks for the tip about the planning meeting. Hope there’s time for public comment, always nervous new developments pop up without neighbors knowing.
Love seeing local churches get involved with family events like the car show. Brings folks together.
Bag day at the library is clutch. I stock up for Christmas gifts and save so much money.
Such a smart idea! Bag day is a true gem for book lovers and gift-givers alike, plus all proceeds help support our local libraries.
Kimmy S.Great idea, Kimmy! I always forget about gifts, but you’re right, it’s such a good way to grab like-new books for cheap.
I wish other cities did these chipping events. We have so many fallen branches every September.
Thanks for mentioning language-assistance at the virtual workshop. Accessibility matters!
Thank you for highlighting that, accessibility and language-assistance are priorities for Arapahoe/Douglas Works! At these workshops.
That 30 minute wait for mulch last year was rough but worth it. Take snacks and be patient.
So many community things happening this week! It makes me love Centennial more. Might try to hit up the book sale and car show.
Had no clue about the car show on Saturday. Thanks for the info, might finally convince my son to show off his old Mustang.
We’re glad you found out in time! The Faith On Wheels car show is a fun way to show off classic rides and enjoy a day out with family and neighbors.
Does anyone know if the mulch is treated, or is it just the raw chipped stuff? Planning to use it in my veggie beds.
Glad to see more free workshops like the financial literacy one. Not everyone learns this stuff in school.
Wish the mulch pickup was open a bit later. Noon is a tough window for folks who work early.
We took our kids to the car show at Arapahoe Road Baptist last year. Lots of cool cars and the live music was a fun bonus.
Really appreciate the heads up about the planning commission meeting. Some changes sneak up if you're not paying attention. I'll check out the agenda.
Bag day at Koelbel Library is the best! Last year I got a ton of cookbooks for just a few bucks. Highly recommend it if you love reading.
That free mulch is such a good idea. I always end up with piles of branches in the fall and never know what to do with them.
