700 acres
Thompson River Ranch is a master-planned residential community consisting of 1,162 single-family lots spanning 700 acres. Although primarily residential, the development also includes a dedicated school site and several commercial pads. Amenities feature a clubhouse with a swimming pool, a trail system, and parks. Galloway team members have been involved in Thompson River Ranch since its inception in 2004, providing design services for filings 5-10, 12, 13, and 15; the Thompson River Ranch pool and clubhouse, North Ridge at Thompson River Ranch, and County Road 3.
Design services include grading, drainage, sanitary sewer, storm sewer, street plans and profiles, and street intersection details. Numerous challenges have been successfully addressed. These include the realignment of a major irrigation ditch, raising a significant portion of the site to comply with FEMA regulations, aligning the I-25 frontage road, combining detention with non-potable irrigation ponds, and routing the flow of an offsite drainage basin of over 3,000 acres through the development. The project also required crossing a high-pressure liquid petroleum main running from Wyoming to Denver. 13.5 acres of enhancements along Larimer County Road 3 improve accessibility to Thompson River Ranch and the nearby travel corridors of Interstate 25 and Highway 34.
Galloway worked with Oakwood Homes to accommodate their various single-family lot designs. Filings 12 and 15 offer 330 single-family homes with a mix of Oakwood’s Park House and Carriage House collections, situated next to the recently constructed Riverview PK-8 school, the current neighborhood park and ball fields, and future pool and clubhouse, offering beautiful views of the Rocky Mountains and Big Thompson River.
