Hilltop Park Was Built to Flood. That's Why Chula Vista Waited So Long to Get It Back.

Hilltop Park has its own rain gauge. Between December 31, 2025, and January 1, 2026, it measured about two inches. That was more than the park's concrete channel could carry, and roughly 250 linear feet of it washed out and buckled. The fast water also ate into the side slopes next to the break, and the City worried about a slope collapse and damage to the public parking lot nearby, according to the City's environmental filing for the channel repair.

The timing made it harder. When that storm hit, crews were already eight months into a project meant to protect those same slopes. A City report on Measure P lists the slope-stabilization contract as awarded on January 3, 2025, with construction scheduled to start April 21, 2025. So if you've walked Hilltop Drive past fencing for most of the last two years, you were watching a park that does a second job, and that job was going on around the construction.

A park with a second job

The City says Hilltop Park was dedicated in 1974 and designed with two roles. In rain it works as an active flood-control system. In dry weather it's a park. On its project page, the City says plainly that "occasional flooding is expected at the park as part of its design."

The channel down the middle of the park is part of the Telegraph Canyon Drainage Basin, which empties into San Diego Bay. The City describes it as a concrete-lined low-flow channel with earthen side slopes. A 2008 regional water-quality study even used a monitoring station called "Telegraph Canyon Creek at Hilltop Park." So the stream that runs past the playground and the walking path has a name, and for water-quality purposes it's a creek.

Chula Vista Emergency Services Manager Marlon King laid out the bigger pattern for 10News in late September: "So the water here in the city flows east to west, and flows out west toward the bay. We have these natural channels that run east to west along our major thoroughfares Telegraph Canyon, Otay River, East 8th Street." Hilltop Park sits on one of those channels, so it gets the water first and the picnics come second.

Why the reopening date kept moving

A park built to flood can only be repaired between rainy seasons, and that explains most of the delays. Here's how the schedule went, pieced together from City documents and local coverage:

1. January 3, 2025. The City awards the slope-stabilization contract and schedules construction to begin April 21, 2025.
2. April 2025. Work begins. According to 10News, the first target for finishing was October 2025.
3. Ahead of the storms. The contractor lays large rocks, called riprap, along both sides of the whole channel as a temporary brake on winter storm flows.
4. December 31, 2025 to January 1, 2026. About two inches of rain fall, and roughly 250 feet of channel fails.
5. April 2026. The City files a separate notice for the channel repair, posted April 16. In 10News coverage from April 10, half the area is fenced, the construction zone had recently flooded, and the target has moved to late fall.
6. May 2026. "Now that the rainy season is officially over," construction picks back up at the western end near the pedestrian bridge and moves east.

By spring, park regulars who talked to 10News said they missed the landscaping and wanted the park back for their dogs.

What the work fixes, and what it leaves alone

The main piece of the project is a turf-reinforcing mat on the slopes along both sides of the channel. It holds the soil in place so fast water can't strip it away. Apart from replacing the section that washed out, the City left the channel itself alone. According to 10News, the City said the project was not scoped to prevent flooding.

The channel repair works the same way. The City's filing says the repair puts the 250 feet back to its "pre-failure condition," with the original alignment, grade and capacity, and "no expansion of capacity." In other words, water will still fill the park in a big storm. The difference is that the slopes, trees and turf are built to come through it.

The City's October 2026 update lists what's already finished:

• The washed-out channel section has been replaced. The repair waited on an environmental permit.
• Turf mat and sod cover three-quarters of the project site.
• 28 new trees replaced diseased ones, and the City bought 28 more for Public Works to plant elsewhere in Chula Vista.
• A new irrigation system is in.
• The temporary riprap is gone. Public Works is reusing those rocks at other drainage channels in the city, including Rohr Park.
• Permanent riprap now sits at the western, downstream end near the pedestrian bridge, behind a four-foot chain-link fence that keeps people out of that area.
• Damaged sidewalk and pavement in the parking lot have been repaired, and trees at the west end that were damaging sidewalk panels and blocking sightlines on the paths have been removed.

The work schedule also made room for wildlife. Crews did a raptor and migratory bird survey before starting and limited construction so nesting birds could fledge. That's one more reason a project like this can't simply speed up when people get impatient.

Where things stand this week

The City set a "Welcome back to Hilltop Park" celebration for Monday, October 26, at 10 a.m. It also planned to move the construction fence at the end of October, reopening half the fenced area because the grass there had met its establishment requirements. Still on the list: final grading, soil amendments, more trees at the western end, and the rest of the turf mat and sod.

For dog owners, 10News reported on September 29 that the City expected the dog park to reopen around October 23. The City's project page says the playground and dog park would stay accessible throughout, so if you saw a gap, that's the difference between the two accounts. The off-leash area itself is fairly new. As the Union-Tribune reported in February 2024, a group called Hilltop Dog Friends asked the City for an off-leash site more than a year before it opened. It ended up next to the sports field after the Parks and Recreation Commission turned down an earlier proposal twice. When the City announced the opening in 2024, it placed the leash-free area on the park's north side and posted daily hours of 7 a.m. to noon. Check the signs on site, since those hours date from that announcement.

Here's what's open, going by the City's information:

• Walking path and bridges. Open for most of the project. Short closures of a couple of days at a time are possible, with notice when the City can give it.
• Playground. Accessible.
• Gazebos. Closed until the whole project is done, and the City is aiming for the end of 2026.

The gazebos are the piece to keep in mind if you're planning a holiday get-together. The 2024 City announcement counts three gazebos in the park's 7.52 acres, along with a children's play area, restrooms and a paved walking trail. Once they reopen, the City's gazebo reservation rules apply. Groups under 25 that aren't using a vendor can use them first-come, first-served. Groups of 25 or more, or any group bringing in a vendor service, need a reservation. Standard park hours are 7 a.m. to 10 p.m. unless a park posts different hours.

The first real test is coming

When 10News visited in late September, it reported that strengthening the channel had become a new priority ahead of what is expected to be a heavy El Niño season. Hilltop is one piece of a citywide push. King told the station the City is using Measure P funds to repair stormwater channels along major roads, and that some of Chula Vista's infrastructure dates to the 1960s. Public Works crews are inspecting and clearing storm drains, making repairs and handing out sandbags.

That changes what to expect from your neighborhood park this winter. When heavy rain fills the Telegraph Canyon channel, Hilltop Park is doing the job it was built for in 1974. The new turf mat, the replaced concrete and the permanent rock at the downstream end are there so the slopes are still standing when the water goes down. If the gazebos are still fenced in December, it's probably because of the rain. Expect the City's next update on the Hilltop Park project page, and you can send questions to [email protected].
