This 0.57-acre lot (approximately 24,950 square feet) offers a rare opportunity in the heart of Boulder County, tucked within the highly desirable Four Mile Creek community, but with no HOA obligations. Surrounded by one-acre estate lots and located on a quiet, tree-lined street, this property offers immediate access to Boulder's renowned bike path system-providing car-free connectivity throughout the city. A neighborhood park lies just steps away, and the area is known for its tight-knit community atmosphere. Significantly, the property has received pre-annexation approval from the City of Boulder and is located in Area II of the Boulder Valley Comprehensive Plan, making it eligible and appropriate for annexation. The city's future land use designation is "low density residential", and the flat parcel is well-suited for residential development consistent with this vision. It is not located in a flood zone, simplifying the development process. City infrastructure is already in place: 8" water and wastewater mains, as well as a 27" storm sewer main, are available within the adjacent right-of-way. No additional fire hydrants are required, and a 40-foot right-of-way extension (not 60 feet) is supported by staff for any future street connection, reducing infrastructure costs. The property will be deeded as a single home lot, making it ideal for a custom home project on a rare, generous parcel within city limits. With clear guidance from the city, access to existing utilities, and a roadmap already established, this property offers a fast-tracked path to annexation and construction. Whether you're a homeowner seeking to build your dream residence or a developer looking for a unique opportunity in a prime Boulder location, this lot combines location, community, and potential-all in one of the most coveted neighborhoods in town. Pre annexation report available. Ditch water rights are available to be purchased from Farmers Ditch Co.
