Look up the address for Watermark Park, the newest green space Orange County has built inside Horizon West, and you'll circle the block once looking for somewhere to leave your car. There isn't a lot. There are no restrooms either. If you were picturing a park with a sign, a bench loop, and a few acres to stretch out in, most of that isn't here. That's the design, not an oversight. When Watermark Park opens on August 31, it opens as a $1.8 million walk-up neighborhood park built for people who can reach it on foot.
Half a mile away sits a very different kind of project. Horizon West Regional Park spans 215 acres, has more than $20 million committed to it so far, and has been opening in pieces since February. It still isn't finished. Two parks, two philosophies about what "open" actually means. Put them side by side and you learn more about how Orange County is trying to keep pace with this stretch of West Orange County than either project tells you on its own.
Watermark Park is small by design and finished on day one, which is the opposite tradeoff Orange County made with its bigger regional projects. There's no parking lot because the county isn't expecting anyone to drive to it. It's meant to be the patch of grass you walk to after dinner, not the destination you plan a Saturday around. Local reporting on the opening tied it directly to a broader county strategy: pair small, immediately usable walk-up parks with the slower, more expensive regional facilities, so residents aren't waiting years for any green space at all while the bigger builds catch up to the area's growth. That growth is real and visible on the roads around it too. The $546 million State Road 516 toll corridor project has already rerouted traffic near Seidel and Avalon roads with overnight detours this year, a reminder that Horizon West's infrastructure, parks included, is being built to catch up with people who already live here.
Here's how the three current projects compare as of this month.
| Project | Opened / Groundbreaking | Cost | What's There | Status Right Now |
|---|---|---|---|---|
| Watermark Park | Opens August 31, 2026 | $1.8 million | Walk-up green space, no parking, no restrooms | Ready to use immediately |
| Horizon West Regional Park, Phase 1A | Opened February 16, 2026 | $15.6 million | Access road, parking, restrooms, inclusive playground, event pavilion, first trail segment | Open now, six months in |
| Horizon West Regional Park, Phase 1B | Broke ground June 18, 2026 | $5.565 million | Splash pad, two-acre lawn, boardwalk and floating dock on Lake Hartley, expanded parking and sidewalks | Under construction, no published completion date |
If your mental picture of Horizon West Regional Park is still a fenced construction site, it's out of date. The 215-acre property first opened back in December 2010, but for more than a decade it offered little beyond limited access for horseback riding and hiking. That changed in February, when Orange County Mayor Jerry Demings and District 1 Commissioner Nicole Wilson hosted the grand opening of Phase 1A, a $15.6 million investment that finally built out the basics: a real access road, utilities, parking, restrooms, an inclusive playground designed for kids of all abilities, an event pavilion, and the first completed segment of trail. That's been open and usable since February 16. By the time you read this, it's had six months of foot traffic, birthday parties, and morning walks behind it, not ahead of it.
The part of the park everyone seems to be asking about, the splash pad and the lake access, is the part still under construction. Orange County broke ground on Phase 1B on June 18, a $5.565 million scope that includes the splash pad itself, a two-acre open lawn, a boardwalk and floating dock overlooking Lake Hartley, and the parking and sidewalk connections needed to tie it all together. The county's parks and recreation manager, Kyle Kent, has said crews are starting at the far end of the property near the future kayak and canoe launch, where power and water lines need to go in underground first, before work moves to the splash pad site and finally to the parking lot expansion near the existing pavilion.
At the June groundbreaking, Commissioner Wilson asked the crowd to
close their eyes and imagine the spray of water
hitting their skin once the splash pad is running. It's an easy image to picture. It's a harder one to put a date on. County estimates for a project like this have suggested construction can take roughly six months once it's fully underway, which would put a reasonable target somewhere around the end of the year, but Orange County hasn't published a firm completion date, and phases 2 and 3, which would eventually add soccer fields, pickleball courts, and a dog park, remain entirely unfunded. One local resident told reporters earlier this year that he'd waited years for the chance to take his own kids kayaking on Lake Hartley the way he did as a kid himself. That's the honest timeline here: real, funded, underway, and not yet ready for a birthday party.
The useful question this fall isn't whether the park is open. It's which kind of open you're dealing with. Watermark Park, once it opens on August 31, is the five-minute walk if you already live close enough to reach it without a car. Horizon West Regional Park's Phase 1A has been fully usable, playground, pavilion, restrooms, and parking included, since before spring break. The splash pad and the Lake Hartley dock are the pieces still worth waiting on, and there's no reason to keep driving past Phase 1B hoping the fencing has come down.
If your Saturday routine already runs through the farmers market and trail scene downtown, this is what's taking shape on the newer, quieter side of Winter Garden, and it's worth adding to the rotation as each piece comes online.
