The proposal for the site at 2350 24th Ave E — currently home to Mont’s Market and Jay’s Cleaners — is part of a standard process at the many properties across Seattle with industrial pasts. Thursday, CHS reported on contamination below the Hilltop Service Station that will also be part of a future state-monitored cleanup process. That property is being lined up for eventual redevelopment. We’re not aware of any current plans for development at the Montlake property.
According to the state, the gas station operated on 24th Ave E rom 1968 to 1990. Petroleum contamination was discovered after a release in 1989 from a leaking underground storage tank. In 1992, the state and a new property owner entered into an agreement where the owner received a state loan to cover a portion of the cleanup costs. A partial cleanup removed leaking tanks, and added a product recovery system that operated until 1997.
