Colorado's First 21st Century Development

team results

Sterling Ranch is a 3,400-acre mixed-use greenfield development project that will provide over 12,000 housing units at build-out, a town center, parks / open space and regional trail amenities as well as civic, retail and commercial facilities all in the context of an integrated master plan. The project incorporates a number of unique community features including rainwater harvesting, water re-use, and community-wide technology systems.

Mortenson’s role on the project is multi-faceted including construction management, general contracting, design-build and development services. In these roles we provide services to three primary customers operating under the overall direction of Sterling Ranch Development which is a family-owned company founded by Harold and Diane Smethills. The three primary customers include Sterling Ranch Development Company, Sterling Ranch Community Authority Board (an authority formed from seven metropolitan districts), and Dominion Water & Sanitation District (a utility district formed to provide wholesale water and sanitation facilities to Sterling Ranch).

The program has been in development for many years, and over the past 18+ months has moved forward through design / preconstruction and reached a major milestone in early-November when the project achieved financial closing. The initial finance package for the project involves a combination of private investment, land sales and pre-paid infrastructure fees, and bond proceeds.

The infrastructure associated with this project includes subdivision grading and utilities, a 1.2-million gallon water tank and off-site water line, sewage lift station and force main along with wastewater treatment plant improvements, an off-site stormwater detention pond and outfall, landscape and park improvements, as well as drainage channel improvements that lay the ground work for a future earthen dam and raw water storage facility.
