Project Overview

In 2017, the City of Boulder purchased the property, located adjacent to West Fourmile Canyon Creek, with plans to minimize displacement, preserve long-term affordability, replace outdated infrastructure, reduce flood risk to the community and introduce new energy-efficient affordable housing options. In 2019, a site plan, informed by inclusive community engagement, was approved and Ponderosa was annexed into the city.


The central goal of the project is to create long-term stability for Ponderosa. As documented in the Ponderosa Resolution, the city is committed to collaborating with the individuals and families that make up the Ponderosa community. Current residents of Ponderosa can choose to stay in their home or buy a new affordable and highly energy-efficient home within the community.
