4730363 MLS
Land with a point of view. Lot 8 of just 12 homesites in the Benchmark subdivision sits at the end of a cul-de-sac on 2.22 rolling acres, bordered by permanently protected Open Space. That distinction matters. Nothing will rise behind you to interrupt a view that stretches from Eldorado Canyon and the Flatirons north to Longs Peak, then opens east across the plains. To the west, sunset becomes part of the architecture before you have drawn the first line. And unlike most raw land, much of the unglamorous work between buying a lot and beginning a home has already been done. The home that once stood here was lost in the December 31, 2021 Marshall Fire. Boulder County has since completed debris removal, and the soil has been tested and cleared. The property qualifies for fast-tracked permitting under Boulder County Land Use Code Article 19-500, with a current plat and soil report available upon request. The rolling topography creates possibilities a flat lot cannot, including potential walkout siting. Zoned ER, with public water and electric, gas, cable and phone at the lot. Benchmark HOA is self-managed at approximately $200 annually, with no additional architectural design review. Approximately 8 miles from Downtown Boulder, within the Boulder Valley RE-2 School District and convenient to Louisville, Lafayette, Denver, DIA and the high country. An incredible opportunity for legacy land in Boulder. 2.22 acres. Protected Open Space. One extraordinary Colorado horizon. What would you build here?
