The Garfield County Commissioners will hold a special meeting today to discuss the Spring Valley Ranch development, a 6,000-acre project that is expected to include 577 homes.Garfield County Manager Ed Green said the meeting will begin at 9 a.m. and will be held at the county administration building at 108 Eighth Street in Glenwood Springs. The meeting is expected to last until 2 p.m.The meeting is described as a work session where public comment will be accepted. There is a possibility the commissioners could vote on the issue.The project would be one of the largest developments in Garfield County history, and would be built southeast of Glenwood Springs. The plan includes 577 housing units and two golf courses. However, that’s far downsized from an earlier plan for the property that called for more than 2,000 homes.The county Planning Commission unanimously approved the proposal in September.
