Site Information

The Holly Park cleanup site is in Seattle’s Beacon Hill neighborhood at 7315 Martin Luther King Jr Way South, Seattle WA. Ecology, with Community Roots Housing (CRH) and HomeSight (HomeSight), has prioritized cleanup of the site in conjunction with redevelopment of the property as a mixed-use community space and affordable housing complex. CRH and HomeSight are cleaning up the site under a legal agreement, called a Prospective Purchaser Consent Decree, with Ecology.

Why This Site Matters

This site cleanup is made possible in part by funding from Ecology’s Affordable Housing Cleanup Grants. Washington is in dire need of affordable housing across the state. Contamination, or even the suspicion of contamination, drives up the costs of housing development. The large cost leaves little incentive for developers to build affordable housing.

In addition to the usual risks of redevelopment, cleaning up contaminated sites can be a complex process with considerable risk. The cost and time associated with cleaning up a site is often poorly understood; as a result, many sites are left vacant or underused for years, even decades. Supporting cleanups for affordable housing helps make sure the cleanup gets done, protecting the community’s health and the environment. Ecology developed the Affordable Housing Cleanup Grant Program (AHCGP) to help advance environmental cleanups for affordable housing developments. These grants can cover remedial action costs, including planning, investigative, and technical work needed to clean up contaminated sites. The purpose of the AHCGP is to expedite the cleanup and redevelopment of contaminated sites into affordable housing use and lessen the impact of cleanup costs.

What Happens Next?

Ecology will consider all comments received and may amend the documents based on your comments. After that, the PPCD and Public Participation Plan will be finalized, and the formal cleanup will begin.  A Remedial Investigation and Feasibility Study will then be completed. Results from the Remedial Investigation and Feasibility Study will lead to a Cleanup Action Plan. Drafts of the Remedial Investigation and Feasibility Study as well as the Cleanup Action Plan will be available for public review and comment.

General Cleanup Process

The Model Toxics Control Act (MTCA) is Washington’s environmental cleanup law. It provides requirements for contaminated site cleanup and sets standards that protect human health and the environment. Ecology enacts the MTCA and oversees cleanups. The MTCA site cleanup process is completed in steps (see graphic below) over a variable timeline.
