A landlocked mesa top.
No water. High wind.
343 homes.

Hillcamp would build 343 houses on top of a landlocked mesa above Lone Tree. There's no water lined up to serve them. The land is high, dry, and windy, and it sits right next to a hillside that already slid once. The only way in or out is a handful of narrow country roads that were never built for a subdivision this size. It's the wrong place for this project.

The City hasn't decided yet. Our attorney's response to the developer's latest submittal is on file, the new wildfire code is now in force, and the next step is a hearing at the Planning Commission. That's what we're watching for, and where we'll need neighbors to show up.

In plain language

We're not against growth. We're against this plan, in this spot. There's no water for it, the roads can't carry the traffic, the fire risk is real, and the ground has already moved once.

Below are the six reasons the proposal does not fit this land, the legal case our attorney has put on the record, and where the fight stands now.

Wildfire code now in effect
Lone Tree's Colorado Wildfire Resiliency Code took effect on July 1, 2026. It requires wider roads, a real second way out, defensible space around homes, and ignition-resistant construction in wildfire-prone areas like this one. The Hillcamp design does not meet those requirements. Because the project has not been approved, it still has to.
NowIn effect
What's at stake

Three ways this plan puts the community at risk.

We are raising three specific problems with this plan. Each one goes to something basic: keeping people safe, protecting the land we share, and honoring the zoning Lone Tree voters approved in 2000.

Life Safety & Wildfire

343 homes would sit on a high-wind mesa served by a single public collector road. South Metro Fire's February 4 referral was conditional, not a full approval. The developer's own materials admit the McArthur emergency access is too steep to work as a public road. The fire code requires a second access road for any development over 30 units, and this one is more than ten times that size.

Geology & Water

The Colorado Geological Survey formally found the developer's geotechnical record insufficient on January 30, 2026. The site sits adjacent to the January 2025 Tract C landslide, currently in litigation. There is no City or State Engineer water-adequacy determination on this project.

The Promise of 2000

Lone Tree voters approved rural-residential zoning for this area in 2000. What the developer wants to build is closer to an urban village, with an amenity center and a density the rural roads out here were never meant to handle. That is not what residents were promised.

What's being proposed

The Hillcamp development, in plain numbers.

Brookfield Residential's resubmittal is currently in its second public-comment period at the City of Lone Tree. These are the numbers our neighborhood would have to live with.

Projected level of service at the I-25 / RidgeGate interchange by 2028

† The interchange is already projected to fail. The RidgeGate and I-25 interchange, which serves Sky Ridge Medical Center, is forecast to reach a failing level of service by 2028 even without Hillcamp. The project would add its trips to an interchange that already cannot keep up. On May 15, 2026, a fatal crash closed I-25 between Happy Canyon and Castle Pines and held residents on those roads for over three hours.

Our position

Six reasons this proposal does not fit this land.

Any one of these is reason enough to turn it down. Put them together and you have a project in the wrong spot, with far more houses than the roads and water out here can handle.

01

There is no water.

The developer's own off-site utility report admits the existing water supply already struggles to hold pressure at peak demand, before a single new home is added. No one has made a formal finding that there is enough water for what is being proposed, and the neighbors on private wells will feel any shortfall first.

Water supply
02

Only one way in, and no real way out.

343 homes would share a single public collector road. The fire code requires a real second way out once a development passes thirty homes. The developer's own materials admit the McArthur emergency access is too steep to ever serve as a public road, and the fire district has given only a conditional approval. In a wildfire on a high-wind mesa, residents would have nowhere to go.

Wildfire & emergency access
03

The ground has already failed once.

The State's geotechnical reviewer found the developer's geological record insufficient in late January. The site sits right next to a January 2025 landslide on the same hillside, which is now in litigation. The developer's own drainage engineer concedes that stormwater run across these slopes "would create unstable slope conditions." Homes and a public road do not belong on ground that has already moved.

Slope & landslide
04

An urban village on rural-residential land.

What the developer calls an addition to a rural neighborhood is really an urban-style village: 343 homes packed around a single arterial, with an amenity center. It does not fit the rural-residential zoning Lone Tree voters approved in 2000, and the roads built for large-lot properties cannot carry it.

Wrong product · Wrong place
05

The Comprehensive Plan does not support it.

Lone Tree's Comprehensive Plan calls for infrastructure-first growth, protection of natural resources, neighborhood compatibility, and preservation of the rural character at the City's edge. This proposal contradicts every one of those policies. The City has previously denied applications on Comprehensive Plan grounds despite a staff recommendation of approval. The same analysis applies here, with more on the record.

Comp Plan conformance
06

The interchange is already projected to fail.

The RidgeGate and I-25 interchange, the one that serves Sky Ridge Medical Center, is already forecast to hit a failing level of service by 2028 without Hillcamp. The project would pile its trips onto an interchange that cannot absorb the growth it already has. The developer's own traffic study understates the 3,136 daily trips Hillcamp would add. On May 15, 2026, a fatal crash closed I-25 between Happy Canyon and Castle Pines and held residents on those roads for more than three hours.

The legal case

The attorney's response, on the record.

On May 26, 2026, the attorney for the Concerned Residents of Surrey Ridge filed a detailed response to the developer's Resubmittal 2. It is not about preference. It walks the City through the specific findings the law requires before approval, and shows why the record as it stands does not support them.

Counsel Jonah G. Hunt · Orten Cavanagh Holmes & Hunt, LLC Filed May 26, 2026 To City of Lone Tree Planning Commission & City Council

What the letter argues

  1. Water adequacy: a mandatory jurisdictional finding under C.R.S. § 29-20-304 that has not been made.
  2. Fire & life safety: the CWRC and the IFC two-access requirement, unmet on the record.
  3. Slope stability: the CGS's Jan. 30 insufficiency finding and § 30-28-136 hazard review.
  4. PDD density: capacity findings required by C.R.S. § 24-67-105 are absent.
  5. Comprehensive Plan: conformance findings the City must make and cannot support.
  6. Traffic: an understated TIS against an already-failing I-25 interchange.
  7. Access & EVA: emergency access designated on deficient rights-of-way.
  8. RidgeGate PDD: inconsistency with the 7th Amendment Main Access Road.
  9. Wildlife: BGEPA, MBTA, and CPW buffer obligations.
  10. Procedure: defects tracing to the City's Feb. 11 directive; deferred findings can't cure them.

Where we are

The process, in motion.

Hillcamp's four applications are pending before the City of Lone Tree. The comment record is built; the decisions ahead happen at the Planning Commission and City Council.

February 2026
First referral comments filed

Surrey Ridge residents, SMFR, CPW, OSNR, and Douglas County submitted formal comments documenting wildfire access deficiencies, density concerns, and ecological impact.

April 7 & 21, 2026
Colorado Wildfire Resiliency Code adopted

The City adopted the new wildfire code on first and second reading. The developer has no vested rights in this plan or its density until the City conditionally approves the application. That means our comments still matter, and the new code applies.

May 26, 2026
Resubmittal 2 referral comments filed

Our attorney's detailed referral response, twelve sections of statutory and code objections, was filed alongside more than 150 resident letters. All of it is now part of the official record. Read the letter →

July 1, 2026
Wildfire code takes effect

The Colorado Wildfire Resiliency Code is now in force in Lone Tree. Because Hillcamp has not been approved, the project has to meet it, and on the current record it does not.

Who we are

An equestrian community standing up for its land.

Surrey Ridge is a covenanted rural-residential and equestrian neighborhood at the north edge of Douglas County. The people here are homeowners, trail riders, and families who moved out for the open sky, the low density, and the quiet.

The Concerned Residents of Surrey Ridge are a coalition of homeowners working alongside Save the Lone Tree Bluffs and other neighborhoods affected by the Hillcamp proposal. Our May 14 community meeting drew a large crowd, which tells you how seriously people here take this.

We're not against building here. We're against building something this land can't support. Get the water right, give it a real way out in a fire, size the roads for the traffic, and leave room for the wildlife and the bluffs, and that's a different conversation. This plan does none of that.
