GLENWOOD SPRINGS – A pair of rural subdivisions, each with more than 300 acres in conservation easements, are winding their way through the Garfield County review process.Springridge II is a 484-acre, 81-unit planned unit development proposed for Dry Park Valley, south of Glenwood Springs.Ranch at Coulter Creek would be comprised of 26 single-family lots on 479 acres on Missouri Heights, five miles northeast of Carbondale.Ranch at Coulter Creek is the southern part of what was once the 1,850-acre Laurence Ranch, according to the sketch plan application filed with Garfield County by Snowmass Land Co.The plan calls for 26 residential building sites ranging from four to 11 acres. Most of the sites would be located along a new road that will run south of the existing County Road 115. A conservation easement to preserve open space, administered by the Aspen Valley Land Trust, will be placed on 305 acres north of the new road.The Garfield County Planning and Zoning Commission reviewed and commented on the Ranch at Coulter Creek’s sketch plan Jan. 8. A primary concern was preserving migration corridors for mule deer and elk through critical winter wildlife habitat.”The P&Z didn’t bring up any issues that will be difficult to deal with,” said Snowmass Land Co. planner Tim Malloy after the meeting.Malloy said Snowmass Land Co. plans to present its preliminary plat to the Garfield County Commissioners in February.Water for Ranch at Coulter Creek would be supplied by a central system. Individual sewage disposal systems on each building lot would handle waste water.The property is currently zoned agricultural/rural/rural residential density, which allows one single-family house for every two acres. The comprehensive plan calls for no more than one house on every 10 acres.Springridge II, located one mile east of Four Mile Road on Dry Park Road, would be built in four phases within the next eight years, according to the development application filed with the county.Most of the homes will be built on the valley floor, but six are planned for sites along Dry Park Road, and 18 at the base of the hillside east of the valley floor. Building site sizes range from 0.7 acres, to a little more than four acres.The conservation easement, administered by Aspen Valley Land Trust, will include hillsides west of Dry Park Road, and 43 acres of valley floor that can be used for agriculture.The Planning and Zoning Commission recommended approval Jan. 8, but with several conditions. Wildlife-related conditions require the developer to warn buyers of the presence of big game hunters and mountain lions in the area. Another condition limits wire fences to 48 inches high, and rail fences to 42 inches, to enable deer and elk to pass through the property. Construction will also be restricted on the hillside along Dry Park Road, due to wildlife habitat.The Garfield County Commissioners have not scheduled a date to review Springridge II. The applicants for that project are S&S Ranch LLC, SBJ Ranch LLC, Freeman Ranch LLC, GSB Ranch LLC, and Wild Mountain Ranch LLC. Pat Fitzgerald of Glenwood Brokers is listed as the developers’ representative.Contact Lynn Burton: 945-8515, ext. 534lburton@postindependent.com
