Thompson River Ranch

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 more than 10 years ago.

Design services provided include grading, drainage, sanitary sewer, storm sewer, street plans and profiles, and street intersection details. Numerous challenges have been successfully addressed, including the realignment of a major irrigation ditch, raising a significant portion of the site to comply with FEMA regulations for minimum floor elevation above the floodplain, aligning the I-25 frontage road, combining detention with non-potable irrigation ponds, routing the flow of an offsite drainage basin of over 3,000 acres through the development, and crossing a high-pressure liquid petroleum main running from Wyoming to Denver. Additionally, 13.5 acres of enhancements along Larimer County Road 3 will improve accessibility to Thompson River Ranch and the nearby travel corridors of Interstate 25 and Highway 34.

Civil infrastructure construction is complete for filings 5-8 and 10, and is ongoing in filings 12, 13, 15, and along Larimer County Road 3. Filings 12 and 15 will 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, future pool and clubhouse, and with beautiful views of the Rocky Mountains and Big Thompson River.
