John Garland Park in Kansas City, Kansas, is shutting down for months during construction to repair a gas-collection system that has degraded over time. Monitors detected methane above the site's action level, and crews will dig into the former landfill beneath the park. The Unified Government of Wyandotte County and Kansas City, Kansas expects construction to begin in October 2026 and last about 120 days, with the park reopening in spring 2027.
The park sits on the former Kansas City Sanitary Landfill, which operated from 1972 to 1974 before being capped, according to fox4kc.com. Buried waste there continues to produce landfill gas as it slowly decomposes, the outlet reports, and recent monitoring found methane above the site's action level at several underground monitoring locations. Natural settling has also shifted portions of the underground gas-collection system, reducing its effectiveness, per the same report.
The Unified Government's Public Works department announced the repair and expansion project for the system beneath the park at 301 Roswell, according to citizenportal.ai. Crews plan to repair portions of the existing system, add new gas-collection wells and install new underground piping to improve collection and curb further underground migration, fox4kc.com reports.
A Landfill's Long History Beneath the Grass
Municipal solid waste, including industrial and commercial material, was dumped at the site for two years, a KDHE spokesperson told KSHB 41 Kansas City. Dave Reno said the landfill once contained couches, papers and other waste, and that the site was built before relevant environmental laws were enacted. The landfill was closed and capped in the 1970s and later redeveloped as a park by the 1980s, according to the Unified Government, as reported by the station.
Kansas and federal investigators identified the need for additional monitoring and site controls at the park between 1987 and 1989, the Unified Government told the outlet, and the park was closed again in the 1990s because of environmental concerns. A gas-collection system and monitors were installed by the 2000s, which led to the park's reopening. The site is considered a brownfield, according to the EPA, and was developed as a model landfill by the EPA, the Unified Government and KDHE.
Why Methane Still Worries Officials
Reno said gas finds the path of least resistance and could migrate into businesses, basements or beneath streets, and that it has already migrated underground beyond the gas-collection system's boundaries. Methane gas can be dangerous when it accumulates in a small space, and the Unified Government is required to take action when monitoring shows the gas has met the threshold. Reno said the park can still be used but that its piping system needs work for safety, and that the project aims to control underground methane migration and prevent flammable concentrations.
A KDHE spokesperson told the station that the gas-collection system uses suction to pull gas to a central location for treatment and reduce risk near the landfill. Consultants separately told citizenportal.ai that methane at the park is managed with extraction wells, header piping and blowers that vent gas about 30 feet skyward. Closed landfills commonly host parks, golf courses or parking, a Burns & McDonnell consultant told the outlet, rather than buildings.
Neighbors Have Long Noticed the Smell
WD Young, who lives a block from the park and has spent his entire life in Kansas City, Kansas, remembers the site as a landfill and said he sometimes notices an odor near it. Reno said the Unified Government will monitor landfill gas at the park for several more decades as waste decomposes.
Cost Estimates Diverge Between Reports
The price tag attached to the work differs depending on the source. KSHB 41 Kansas City reports that the Unified Government's solid waste office described the work as a roughly $656,000 safety upgrade, with residents covering the cost through their monthly trash and recycling collection user fee. Fox4kc.com, however, reports the project is estimated to cost $1.8 million and be completed by June 2027. The dossier does not reconcile the two figures or say whether they reflect different phases or scopes of work.
A Familiar Problem in Other Cities
Kansas City, Kansas is not alone in grappling with a park built over buried trash. César Chávez Park in Berkeley, California, was also built atop a municipal landfill that continues to generate methane, according to the Los Angeles Times. That landfill closed in 1990, and the city now operates an underground system that collects the gas and torches it at a large mechanical flare in the park. Since 2019, Berkeley's gas-control system, flare and gas wells have periodically gone offline for hours or several days, often because of power outages, and the Bay Area Air Quality Management District has fined the city after finding explosive methane levels leaking from at least two cracked gas-collection wells, issuing at least 14 air-quality violations in 2023 alone.
