Endorsement Awarding Native Sun Construction, Inc., the Contract to Construct the Colorado Front Range Trail through Castle Rock






An endorsement is requested to award a future construction contract to Native Sun Construction, Inc., (NSC) for the Colorado Front Range Trail at Castle Rock for an amount of $6,432,852.97, plus a 10% Town-managed contingency in the amount of $643,285.00, for a total project cost of $7,076,137.97. 


With the support of many stakeholders, Colorado State Parks initiated the Colorado Front Range Trail (CFRT) project in 2003 to set the vision of a multi-purpose trail connecting the Front Range from New Mexico to Wyoming. Castle Rock will serve as the network’s southern crossroads, eventually linking Douglas County with Denver via the East Plum Creek, Hangman’s Gulch, Woodlands and McMurdo Gulch trails to the Cherry Creek Regional Trail. Completion of these trail segments have been identified as priorities within the Council-approved Parks and Recreation Department Master Plan and Strategic Plan and will complete Castle Rock’s portion of CFRT.   


Construction will commence fall 2022 and include approximately 5 miles of trail located in three separate areas of Town including the Cobblestone Ranch, Terrain and Montane neighborhoods (Attachment A).  The scope of work generally includes site grading, concrete flatwork, stormwater culverts, box culvert creek crossings, pedestrian bridge crossings, retaining walls (concrete, block and sculpted shotcrete), a railroad steel canopy structure and general erosion control measures. Construction is anticipated to be complete by September 15, 2023.




In 2019, the Town received a $2 million grant award from Great Outdoors Colorado for trail construction, which will also include partnerships to help support and drive the project. The proposed team will include the Town, Douglas County, as well as the developers of the Terrain (Land Perspectives, LLC) and Montane (Toll Brothers), Douglas Land Conservancy and Lowell Ranch (Colorado Agricultural Leadership Foundation).  


A public meeting was held at Wrangler Park on September 1, 2021 to review the design and alignment of the trail. The project is located within Town-owned open space and easements. Project details and updates are available at, and press releases will be issued to inform residents project-related events as scheduled.




The Town issued a Request for Bids (IFB) via Rocky Mountain BidNet, and two responses were received. The low bid was provided by Native Sun Construction:



HEI Civil Inc.

 $      7,158,892.32

Native Sun Construction

 $      6,432,852.97


In addition to the $2 million grant award from Great Outdoors Colorado, the project will be funded through the Annual Trail Improvements Account. Total project costs, including contingency, are $7,076,137.97 and will be expensed to account item number # 110-5275-452.75-14. The Annual Trail Improvements account has a current balance of $6,155,338.71 for the project. An additional $1,539,456.26 is needed from General Fund Balance to enter into the construction contract and cover other project related costs not held under the proposed contract with NSC. The additional funds needed will be deducted from the 2023 and 2024 trails account budget allocations. Trail projects planned for 2023 and 2024 will be shifted to 2025 and beyond.




“I move to endorse the project’s contractor award as introduced by title.”
