The week of August 10–16, 2026 brings a noticeable change of rhythm to Centennial. Backpacks are replacing pool bags for some families, City business continues to shape what comes next, one neighborhood library is temporarily closing its doors, and there are still plenty of reasons to enjoy these long Colorado evenings.
It is one of those weeks when summer and fall seem to occupy the same room. Here is what Centennial residents should have on their radar.
What’s New: School Is Back for Part of Centennial
For families in Littleton Public Schools, Tuesday, August 11, marks the beginning of the 2026–27 school year. At Centennial’s Arapahoe High School, freshmen and new students begin with Link Crew orientation Monday before the full school returns Tuesday. Athletic Night follows Wednesday, with a student Back-to-School Dance Friday evening. (Littleton Public Schools)
Meanwhile, Centennial families in Cherry Creek Schools are still in preparation mode. August 10–14 are teacher workdays, with school phase-in beginning August 17. Some individual Centennial schools are also holding meet-and-greet events this week, so families should check their specific school calendar rather than assuming every campus follows exactly the same first-day schedule. (Heritage Elementary School)
The result is a staggered back-to-school week across Centennial. For everyone on the road, that means it is also time to reacquaint ourselves with school zones, buses, crosswalks and slightly busier mornings.
What’s Happening: Centennial City Council Meets
Residents interested in the decisions shaping Centennial can follow the City of Centennial calendar for the City Council meeting scheduled Tuesday, August 11, at the Centennial Civic Center.
Local government rarely arrives with flashing lights, but decisions made there eventually become roads, services, budgets, development policies and community priorities. Following even one meeting or agenda is an easy way to replace “I wonder what the City is doing about that?” with something considerably more useful: information. (Centennial, CO)
Good to Know: Castlewood Library Temporarily Closes
One practical change begins this week. Castlewood Library at 6739 S. Uinta Street in Centennial is temporarily closed from August 9 through October 31. Arapahoe Libraries currently lists the location as closed until November 1. Residents who normally use Castlewood should check other Arapahoe Libraries locations for holds, programs, study space and other services during the closure. (Arapahoe Libraries)
What’s Next: Centennial Keeps Moving
Drivers along East Arapahoe Road should continue watching for construction activity associated with the Lone Tree Creek Trail Underpass between Revere Parkway and Potomac Street. The City says intermittent off-peak lane closures will continue as crews build a dedicated pedestrian and bicycle connection beneath Arapahoe Road. Completion is estimated for early spring 2027. (Centennial, CO)
And while school schedules are returning, summer has not packed its suitcase yet. Centennial Center Park’s splash pad remains open daily from 10 a.m. to 8 p.m. through Labor Day, giving families an easy, free option for an after-school cooldown. (Centennial, CO)
This week’s Centennial Pulse is really about transition. Some neighbors are heading back to classrooms. Others are following City decisions, adjusting familiar routines or squeezing one more golden evening out of August.
Know what’s new. See what’s next. And perhaps most importantly, keep finding small ways to feel connected to the Centennial community we share.

Love that there are still summer evenings left. Backyard grill and a trip to the splash pad sounds just right this week.
That sounds like the perfect way to savor what’s left of summer, enjoy every golden August evening and the splash pad while it’s open!
Will there be any alternative Castlewood library events at other locations or outdoors during the closure? My book group is wondering.
Great question, during Castlewood’s closure, Arapahoe Libraries encourages groups to check other branch calendars for events, and some book groups and programs may be relocated. It's worth reaching out to your librarian to discuss options for alternate meeting spaces.
Our family tradition is getting ice cream after the first day. Glad the splash pad is still going so we can double up!
D StewartThat sounds like such a fun tradition! My kids love the splash pad too, so we might have to steal this idea. Hope you all have a great start to the school year!
Link Crew at Arapahoe was super helpful for my son last year. Props to the older students volunteering for it.
I love the feeling in the air when school starts back up, but I’ll miss not having to fight traffic every morning!
Thank you for including the Civic Center dates. I always forget when the city council is happening.
Appreciate the heads up on library service changes. Anyone know if book holds will transfer automatically to another branch?
Glad to see the underpass project pushing forward. Crossing on bike right now is honestly pretty sketchy.
We agree, safe bike and pedestrian connections are a big step forward for Arapahoe Road, and we're glad the city is prioritizing the underpass for spring 2027.
Never went to a city council meeting before but maybe I should. Seems like it actually impacts our day-to-day more than you'd think.
Absolutely, city council decisions shape everything from roads to recreation, and attending even once can provide insights into what’s changing in Centennial.
Angie LeeYou definitely should! I went once just to see what it's like and learned a lot. It's pretty low-key, but you see how decisions get made.
I wish Cherry Creek and Littleton could line up first days better. Makes carpooling a nightmare for blended families.
Rob GagnonSame boat here. Our kids are split between the two districts and it gets so confusing every August. Would be great if they synced up at least a bit more!
We hear you, the staggered start dates can complicate planning for families in both districts. Each district sets its schedule independently, but checking individual school calendars can help with some of the confusion.
Big thanks for the reminder about school zones. I always end up rushing and forget those flashing lights are back.
My family moved here last year, it's nice to get a heads-up about events and transitions. Still feels new but these updates help.
Welcome to Centennial! We're glad these updates help you feel more connected, and there’s plenty more to discover as you settle in.
What is the Link Crew thing at Arapahoe? Is that just for incoming freshmen?
Feels like the city’s got a lot happening at once. Hope the council keeps community input in mind, especially with budget talks coming up.
Does anyone know if the Centennial Center Park playground is still open while the splash pad runs?
I use the Castlewood branch every week for study space, so this closure is a bummer. Thanks for giving a clear time frame at least.
Cherry Creek meet-and-greets are the best way to break first day nerves. Met my twins’ teacher last year and it helped a ton.
Anyone else dreading packing lunches again? Back to school kind of sneaks up on you!
Wish the Lone Tree Creek Trail underpass was getting done sooner, but it'll be nice to cross Arapahoe safer when it's finished.
So grateful Centennial still does these community updates. Always find something I didn’t know I needed.
Nice reminder about crosswalks and bus stops. The first week back is always a little nuts out there.
Can't say I'm ready for back to school quite yet. Still trying to enjoy these summer nights on the patio as long as possible.
Every year the staggered school schedules trip me up. Our neighbor's kids are already packing up backpacks and mine are still living in swimsuits.
You're not alone, this is one of those transition weeks where summer and fall overlap in Centennial, and every family’s calendar seems to look a little different!
City council meetings could use more people tuning in. Last time I checked, there were like six folks in the audience. More voices can only help.
Splash pad still going till Labor Day? My kids are obsessed! Love that the city keeps it open a bit longer.
Yes, the splash pad at Centennial Center Park will remain open through Labor Day, giving everyone a little more summer fun before the season wraps up.
My youngest starts at Arapahoe High this year and she's super nervous about that first day. Link Crew orientation sounds like a good idea.
Link Crew orientation at Arapahoe is designed just for students like her, helping new Warriors connect and settle in before the first official day.
Linda ParkMy son went through Link Crew last year and it really helped him feel less anxious. There were a lot of friendly upperclassmen showing them around. Hope your daughter has a great first week!
Thanks for the heads up about the construction on Arapahoe. I've hit those lane closures a few times and never knew what was going on.
Aw man, Castlewood is my go-to library. Guess I'll have to check out Koelbel for a while. Hope they're back open soon.
Noticed a lot more pedestrians on Potomac lately. Glad the underpass is going in, but can’t wait for it to be finished.
Library closure is rough for our book club. Guess we’ll have to get creative for meeting spots for a few months.
Whoa, wasn’t expecting construction crews along Arapahoe until next spring! Hope traffic doesn’t get too insane during rush hour.
I feel so unprepared for school starting already, ha. Summer went by way too fast this year.
Kind of wish city council meetings were streamed live with comments. Not everyone can make it Tuesday nights.
Kinda wild that some schools start next week and others still have a few days. It always throws off my routine driving around!
Greg W.Totally feel you. I always forget which school is starting when, so I get caught off guard by the new traffic patterns. It takes me a whole week to adjust!
Bummed about Castlewood closing, but Koelbel Library isn’t too far. Anyone know if their study rooms are good?
Koelbel Library is a great alternative, its study rooms are popular and can be reserved in advance, so you should find a quiet spot there while Castlewood is closed.
Centennial Center Park is such a gem. The splash pad is where you’ll find us every evening until fall sports eat up our schedule!
The underpass project is taking ages. Anyone know why it isn’t done yet? Feels like it’s always under construction.
Thanks for including info for both districts. It’s always confusing with Cherry Creek and Littleton starting different days.
We’re glad it’s helpful! Centennial’s overlapping district calendars can trip up even seasoned families, so we always try to clarify both start dates.
Splash pad after school until Labor Day? Yes please! That’s going straight on my aftercare list for my daughter.
Appreciate the quick city council reminder. The agendas are long, but it’s good to know what’s up before it happens.
Thank you for saying so! We agree, it’s much easier to stay engaged if you have a chance to look at the issues before decisions are made.
Kind of weird that some schools are back and others aren’t, but I guess it means less chaos all at once.
Already seeing more cars in the school zones this week. Please everyone slow down.
Glad for the heads up on the Lone Tree Creek Trail work. I bike through there and would’ve been shocked at the lane changes.
Ron WalkerSame here, Ron. I wish the city posted even bigger signs about those projects. A few times last year I ended up stuck mid-ride because of surprise detours! Stay safe out there.
We’ll miss Castlewood Library! It’s our go to for storytime with my kids. Hoping the other branches aren’t too crowded now.
