Project Overview

Ponderosa Mobile Home Park was annexed into the City of Boulder in 2019 and is located near West Fourmile Canyon Creek. In 2017, the city purchased the site with plans to preserve long-term affordability, replace outdated infrastructure and reduce flood risk to the community. Using findings from the West Fourmile Canyon Creek Study, city staff explored options for stability and minimizing future flood impacts at Ponderosa. Options ranged from “no action” to “city purchase with infrastructure replacement, identification of home replacement options and a long-term owner to maintain affordability.”


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 move into a new affordable and highly energy-efficient home.
