Lost Valley Ranch

Lost Valley Ranch is an all-inclusive, 350-acre dude ranch located in Sedalia, CO. Galloway is providing multidisciplinary services for a large-scale, full-site phased update over the next eight to ten years. Services include architectural design, civil engineering, survey, site development, MEP engineering, structural engineering, landscape architecture, and interior design.

Galloway’s survey team has completed as-built HDS scanning of the lodge, and survey of 113 acres of the property utilizing drones and standard survey equipment. Our civil engineering team is providing comprehensive services for the entire site. Grading and erosion control are required for the construction of the proposed bunkhouses and leadership cabin as well as the placement of a bridge to span across Goose Creek. This will provide an expanded parking lot as well as a secondary access point designed for staff and fire truck access. A culvert analysis was performed for any crossing along the proposed roadway and the team collaborated with Jefferson County to obtain a waiver for the roadway width. A hydraulic analysis was conducted on the impact of the bridge spanning Goose Creek to ensure the design could withstand both 10-year and 100-year storm events with additional freeboard.

Our architecture team is collaborating with the Lost Valley Ranch manager and staff to create a vision of what they want the ranch to look like in ten years. The vision involves remodeling recommendations for existing buildings, as well as new buildings for expansion purposes. Construction started in the summer of 2024.

Projects to be completed in the first couple years include:

• 2 Staff Bunkhouses: New 6,500 sf two-story building for employees to live in while working at the Ranch. It will house between 40-80 employees.
• Manager Housing: Two new single-family, cabin-style housing facilities for upper management and small families.
• Review site drainage issues for recommendations on corrections needed
• New employee parking lot
• Create two new roads for construction use and future expansion including a new bridge crossing

Future projects in the next eight to ten years:

• Lodge remodel with a full commercial kitchen remodel.
• Trading Post: Full building remodel or potential rebuild. This houses the ranch store and the ice cream store.
• Maintenance Building: Construct a new maintenance building that is larger, more functional, and farther away from guests.
• Laundry Facilities: Remodel/expansion of existing commercial laundry room, which is too small and not fully functional, into adjacent space.
• Guest Cabin Expansion: The addition of 6-7 new, larger family-style guest cabins that can house up to ten guests in one cabin.
• Outdoor Rodeo Facility: New facility with seating and round pen for guest use.
• Potential remodel of 2-4 existing guest cabins, including converting current upper management housing back into guest cabins once they are relocated.
