About the Site Walk
On your scheduled day, meet at the project sign located near High Note Avenue and Lyric Street. Street parking is available on Lyric Street. Here is a Google Maps pin of the meeting location.

The site walk will be entirely on new concrete sidewalks along the perimeter of the park site. City staff will bring printouts of the plan and walk the length of the site. The total distance is about 1 mile round trip with frequent stops and should take about an hour.

The City of Lone Tree and South Suburban Parks and Recreation are working collaboratively to build Lone Tree’s first and only regional park. High Note Regional Park, previously known as Lone Tree Regional Park, will be located along Happy Canyon Creek near I-25 and RidgeGate Parkway.

The 80-acre park has long been planned for the area and was included in the vision that Lone Tree residents voted for when the land was annexed into the City in 2000. With surrounding development now underway, the time has come to construct phase one of this generational project.

Friends of High Note Park

Friends of High Note Park is a future organization made up of community members who will be dedicated to supporting the development and ongoing success of High Note Regional Park. The group will collaborate with the City of Lone Tree and South Suburban Parks and Recreation to ensure the park becomes a vibrant and accessible space for all residents.

Early 2025 Design Update

The landscape architect for the project, OJB, has made updates to the design based on community input and the firm’s experience with other parks. The design updates were presented at the February 2025 Friends of High Note Meeting.

The Site Plan

The preferred concept was selected for advancement because of it’s alignment with the community’s input, strong connectivity within and outside the park, and for using creative design approaches to address challenging site conditions.

Key achievements of the site plan include:

- Incorporation of signature elements not currently found in the area, including a festival terrace, amphitheater, and signature accessible playground.
- Developing a unique promenade known as The Braid- a unifying thread that runs the length of the park. The Braid is an interwoven promenade of paths that all the programming elements align across. It also provides a linear connection between the north and south side of the park which is bisected by a future road.
- Accommodating a diverse range of both passive and active recreation opportunities.
- Creatively embracing the natural grade of the site to minimize the use of retaining walls and create more natural slopes that better blend into the natural landscape.

The selected concept is shown below. This is an updated concept plan completed in early 2025 that incorporates community input received after the initial concept plan was developed in 2021 and again in 2024.

Donation, Sponsorship, and Business Opportunities

In addition to local government funds and grant opportunities, community donors, sponsors, and businesses will be necessary to bring this project to life.

Business Opportunities
In the coming months, a simple Request for Information (RFI) will be issued to gauge business interest in supporting the park. While the main focus is in finding the right restaurant partner to enter a ground lease for the restaurant pad, other business ideas (with a focus on food and beverage) are encouraged to be submitted.

Donations & Sponsorships
In the coming months, donor information packets and information will become available. The project will consider both corporate and individual donors.

Top Priorities for Funding

The top priorities for donations, sponsorships, and business partnership include:

Funding the signature playground
Funding the amphitheater stage structure
Finding the right restaurant partner
Funding the overlook hill, including challenge steps and signature sculpture
Funding activity “rooms” along The Braid Promenade
Funding Athletic Fields
Funding public art throughout the park

Prime Location at I-25 and RidgeGate Parkway

High Note Regional Park will be located at a prime location, with easy access to Denver and Colorado Springs. The park will also be connected to the Denver Metro from RidgeGate Station, with trains running to Union Station (E Line) and into Aurora (R Line).

Catalyst for the Lone Tree City Center

High Note Regional Park will be a catalyst for the Lone Tree City Center, a coming 50-block urban center and downtown for the south metro area. The City Center will contribute millions in tax revenue each year to support public services. The park will also benefit from the infrastructure improvements being made to support the millions of visitors that will come to the area.

Park Development Process

The regional park’s master planning effort began in 2020 after Shea Homes began planning a new neighborhood in RidgeGate’s Southwest Village, now known as Lyric.

Planning the regional park concurrently with the neighborhood development and other projects in the area has allowed for better connectivity, intentional topographic design, and proactive infrastructure development. It also lets future residents know what the plans for the area are before buying property.

2000: Lone Tree residents vote to annex the RidgeGate area, including the vision for a future regional park and adjacent City Center.
2019: Shea Homes began planning the Southwest Village neighborhood (now known as Lyric).
2020: Lone Tree and South Suburban began initial study and planning efforts for the regional park.
2021: Public input and concept development.
2022: Concept selection & design development.
2022-2024: Identify funding partners
2024: Artaic Group Hired as Project Manager and ECI Hired as Contractor
2024: OJB Hired As Project Landscape Architect
2024: Advance Design & Determine Phase One
2025-2026: Break Ground And Construct Phase One
2027: Open Phase One to the Public

Community Vision

The regional park will be a destination park, creating a new central gathering place in north-central Douglas County.

As part of the park’s initial visioning process, the following goals were identified:

Signature Park – Create a signature regional park for everyone, incorporating principles identified in the SSPRD Master Plan: Quality First, Enrich Wellness, Connect to Nature, and Lead Sustainability
Access for All to the Natural Environment – Offer all members of the community access to the unique natural environment, especially the creek and related water features
Riparian Habitat – Protect and enhance a diverse riparian habitat
Environmentally-friendly Stormwater Management – Design a park that incorporates state-of-the-art floodplain and storm water management
Active & Passive Recreation – Accommodate the active recreation demands of a growing community of people of all ages and abilities with synthetic multi-purpose fields, sports courts, picnic areas, gathering places, trails, etc.
Connections – Connect the regional park to the historic Schweiger Ranch, Bluffs open space, Reuter-Hess Reservoir, and the regional trail network, including the Cherry Creek system and surrounding communities
Community Events – Accommodate vibrant community events throughout the year
Partnering – Identify opportunities and programs to partner with public, private, and non-profit organizations to enhance access to everyone in the community
Transit Accessible – Take advantage of unparalleled transit access with RTD’s RidgeGate Station nearby

When will the park be built?

The City and South Suburban are currently finalizing funding agreements to advance the project to construction, including additional funding partners and grant opportunities. The project is anticipated to break ground in 2025 with a first phase anticipated to open to the public in 2027.

How much will the park cost?

This park is a generational project that will be built in phases as funding becomes available. The project’s first phase is anticipated to cost $32 million, including $22 million currently budgeted by South Suburban and the City of Lone Tree. The City currently has a funding application in with Douglas County to partner on $8 million needed for phase one. The project budget may increase if additional funding partners, private donors, or grant opportunities become available to expand the first phase of the project.

Public Input

Join us for a Community Site Walk
Come learn about the coming High Note Regional Park and give input on the project. Site walks are happening from June through September 2024! Click here for information and to sign up.

A survey of community members in the spring of 2021 guided development of the concept plan. Since then, the project has been presented to community groups and at open houses, including public meetings for the Lone Tree Elevated Comprehensive Plan update.

In addition, the project was presented to a number of citizen lead advisory groups for input, including Lone Tree’s Recreation Advisory Committee, Planning Commission, and Arts Commission and Douglas County’s Parks Advisory Committee and Open Space Advisory Committee.

The latest update to the concept plan in spring 2024 incorporated feedback received after the initial concept plan was developed.

RidgeGate East South Suburban Master Plan Addendum

In addition to public outreach specific to the regional park, the planning work has considered the public outreach already completed for the addendum to South Suburban’s Master Plan outlining priorities specific to RidgeGate East, including the regional park site. This public engagement effort looked at the parks system in RidgeGate East as a whole, connected system. The 2018 addendum can be viewed here.

Signage at the regional park site gets the word out to people buying housing near the park so they know what they are moving in next to.

Addressing Public Comments Received

Not all feedback received from the public was able to be incorporated into the selected concept plan. Below is a summary table of the most common comments received and the explanation for why they were not able to be included in this project.

It turns out, when input is solicited for parks there are a lot of requests for additional elements, but there are rarely requests to take things away! Elements prioritized for the regional park are more active/intensive elements that could not be accommodated in other parts of Lone Tree. For ideas that were not able to be incorporated, know that the City and South Suburban are keeping these in mind as future neighborhood and community parks are built in the RidgeGate neighborhood.

In addition to the regional park, future facilities and parkland required of the RidgeGate developer include:

- 5 acres/thousand residents of “Neighborhood Parks” for future neighborhoods
- 11 acres for a future recreation center across from the regional park on RidgeGate Pkwy
- 25 acres for a future ballfeild complex, that may also include additional courts
- 27 acres of larger “Village Parks”
- 14.5 acres of parks and plazas in the City Center
- 404 acres of open space

The input below that was unable to be incorporated in the regional park may still be incorporated in the future parks/facilities outlined above.

Concurrent Projects

The master planning process has taken advantage of concurrent projects happening around and within the regional park site.

Happy Canyon Trail

Rampart Range Metro District and the Mile High Flood District are already constructing the Happy Canyon Trail, a new trail that will connect Douglas County’s East/West Trail up on the bluffs, Schweiger Ranch, and the future Regional Park. The trail will generally run north-to-south, going under RidgeGate Parkway and eventually connecting to Lincoln Avenue.

The trail will connect to other trails in the RidgeGate area and eventually connect to the Lone Tree City Center.
