Reconstructing and Revitalizing a Southwest Colorado Mountain Ski Resort


As part of a multi-phase, 20-year, $100-million master plan project, Purgatory Village Land Co. sought to revitalize its lodging and access options at the base of Purgatory Resort (formerly Durango Mountain Resort) in the rugged San Juan Mountains in Southwest Colorado.


SEH served as lead civil engineer for the site design of the base facility for the ski area. The scope of work also included designing a new arrival court drop-off area to accommodate buses and recreational vehicles. Complicating the project is the fact that the resort resembles a tight urban environment, with the SEH team leveraging its experience to provide site design amidst a number of pre-existing buildings and commercial facilities.

The Purgatory Lodge itself is a mixed-use building that was constructed in phases and included relocation of major utilities, building demolition, street and pedestrian access designs and integration of a number of privately owned residential and commercial units.

The first phase of the project included approximately 15,000 square feet of commercial use space and 22,000 square feet of club uses, as well as 36 residential condominium units. In addition, there is a 66-vehicle underground parking garage, a pedestrian plaza and skier access considerations.

The SEH team also performed a drainage study, designed a sub-surface stormwater conveyance for a water quality treatment facility, and designed the facility itself. Ongoing work by the project team includes the development of out-parcels for residential and mixed-uses over a 20-year period.
