The region of Central Arizona has a legacy of open spaces that have supported Arizona’s rapid growth to
this present day. Still, park systems’ growth and operating resources have not kept pace with population
and economic recovery since the 2008 recession. This limited financial capacity and additional demand,
compromise stewardship success in treasured natural areas and diminish quality visitor experiences
for residents and visitors alike. Therefore, Sonoran Institute (SI), in partnership with the Central Arizona
Conservation Alliance (CAZCA), investigated the “state of the parks” within the region to identify the areas of
greatest need among natural, desert open space parks.

The Regional Open Space Strategy (ROSS) is a first iteration road map and action agenda. It is in no way exhaustive. It lays out fundamental initial steps toward unified, cohesive, regional open space conservation, but acknowledges there still exists gaps in information, collaboration, and coordination. In the ROSS, we put forward clear, concise objectives and specific on-the-ground, highly achievable strategies inclusive of the social, cultural, environmental values of communities. When fully implemented, the ROSS will deliver a connected, distinctive, well-managed open space network that will enhance the unique character of the region and enable Maricopa County to realize the full benefits of open space for people, environment, and economy. This is the 2018 update.
