Quick Answer: What's Changing at Garden City Compost?

The Missoula City Council approved an $8.5 million construction project for Garden City Compost in May 2025. Key improvements include concrete pads for compost processing, enhanced drainage systems, and better management of PFAS contamination. The funding comes from the American Rescue Plan Act (ARPA) — federal COVID-19 relief money that the city already has in hand. For residents, this means more efficient compost processing, better environmental protections, and a more sustainable waste system for our community.

Why This Upgrade Matters for Missoula

Garden City Compost has been operating on a transitional site since the City of Missoula acquired the facility in 2017. For eight years, the composting operation has made do with temporary infrastructure while city planners developed a long-term vision. This $8.5 million investment finally brings that vision to life.

"This is a fantastic move for our facility and for the community," said Jason Duffin, Compost Facility Manager at Garden City Compost. The improvements address both operational efficiency and environmental safety — two priorities that directly impact everyone who drops off yard waste or picks up finished compost.

What's Included in the $8.5 Million Project

The construction project includes several major components designed to modernize the composting operation:

Concrete Processing Pads: The new concrete pads give compost a stable, contained surface to sit on during decomposition. This prevents ground contamination and makes the facility easier to maintain.

Improved Drainage Systems: Better drainage means less standing water, fewer odor issues, and more efficient compost processing throughout Montana's varying weather conditions.

PFAS Contamination Management: One major focus of the upgrade is managing PFAS (per- and polyfluoroalkyl substances) — chemicals found in many consumer products that don't break down naturally. The new infrastructure will help the facility monitor and manage these contaminants more effectively.

How the Project Is Funded

The funding package breaks down as follows:

• $4.7 million — American Rescue Plan Act (ARPA) federal grant
• Matching funds — City of Missoula Wastewater Enterprise Fund

This means no new taxes or fees for residents. The city already has the ARPA funding in hand, making this a rare opportunity to make significant infrastructure improvements without burdening local taxpayers.

The ARPA funds come from federal COVID-19 relief legislation passed by Congress in 2021. Communities across Montana have been using these one-time funds for various capital projects — Missoula's choice to invest in composting infrastructure reflects the city's commitment to sustainability and environmental stewardship.

What This Means for Your Composting Routine

If you already drop off yard waste at Garden City Compost, you'll likely notice improvements in service and efficiency once construction is complete. The facility will be able to process material faster and produce higher-quality finished compost.

For residents who have been curious about composting but haven't started yet, these upgrades signal that Missoula is serious about supporting organic waste diversion. The improved facility makes it easier than ever to keep food scraps and yard waste out of the landfill.

FAQ: Garden City Compost Upgrade

Q: Will the compost facility close during construction?
A: No — Garden City Compost will remain open during the upgrade project. There may be temporary adjustments to hours or drop-off locations, but the facility plans to stay operational throughout construction.

Q: How much of the $8.5 million comes from local taxes?
A: None of it. The project is funded entirely through the American Rescue Plan Act (federal COVID-19 relief funds) and the city's Wastewater Enterprise Fund. No new local taxes or fees are being used.

Q: What is PFAS and why does it matter for composting?
A: PFAS are synthetic chemicals found in many consumer products that don't break down naturally. They can contaminate soil and water. The new infrastructure will help Garden City Compost better monitor and manage these substances.
