A Canadian firm that wants to build a “Nordic spa” near Roxborough State Park goes before Douglas County leaders for the first time Tuesday evening. The county commission is set to vote on whether to approve a metro district for a 35-acre site largely surrounded by Arrowhead Golf Course. The land, which features jagged red rock formations, is owned by Calgary-based Pomeroy Lodging. Metro districts are quasi-governmental bodies that have a number of legal powers and financial tools that aid in development of a property.
