What Maricopa Trail & Park Foundation does
Mission
The Maricopa Trail and Park Foundation is dedicated to protecting, promoting, developing and maintaining one of the nation's largest county park systems, as well as the 321-mile trail that traverses Maricopa county and connects the county's regional parks.
As stated on its FY2025 Form 990.
Programs
The purpose of the Arizona Office of Tourism grant is to connect the Maricopa Trail to another trail - the Sun Corridor Trail. The mission of this program was also to establish a "Trail Town Program." This program provides a nexus for greater Maricopa Trail awareness, enhanced regional connectivity, and increased quality of life as communities join in experiencing and celebrating the shared natural resource of the Maricopa Trail and its benefits. The trail is now fully constructed and maintenance of the trail has been turned over to Maricopa County.

The organization over time
Each line starts at 100 in 2017, so what you read is the shape rather than the size: 150 means half as much again as 2017, 50 means half. The number beside each label in the key is where it ended. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2019 to 2020, from $149k to $81k (−45%).
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
Government-grant reliance: 2025 94%. Grants only. Government contracts and fees sit inside program revenue.
