The City of Gresham Parks & Recreation Division (GPRD) requested that the Portland State University Population Research Center (PRC) prepare a demographic profile, population forecasts, and parks and natural areas access analyses (‘parks access’) for the City of Gresham and its Springwater and Pleasant Valley planning areas. The study will inform GPRD’s Parks, Natural Areas, and Trails Comprehensive Planning effort, currently underway.

The demographic profile discusses current conditions and likely future trends for population, housing, and households, with a focus on age and race/ethnicity. It includes many demographic map ‘layers’, which in Geographic Information Systems (GIS) software can be overlayed on parks access layers.

Year-2020 population forecasts are prepared by age and sex for the City of Gresham and, for the general population, by Gresham’s neighborhoods, Pleasant Valley, and Springwater.

Parks access analyses focus on GPRD parkland typologies: Neighborhood and Community parks, Natural Areas (Open Space), and Trails. One model includes versions for existing and proposed conditions, while the other two build on the first, adding an analysis of parkland quality, proximity to schools, and proximity to parks outside Gresham. Model summaries and other parks access data, by neighborhood, are provided in an appendix.

The report is divided into two main sections: Section I includes the demographic profile and population forecasts. Section II covers the parks access analyses. Together, both sections hold insights and analytical tools with which the City of Gresham can move forward confidently in its Comprehensive Planning effort.
