About the Superfund Redevelopment Initiative
This nationally coordinated effort provides EPA and its partners with a process to return Superfund sites to productive use. Learn more at Superfund Redevelopment Initiative.
Redevelopment at the Site
The goal for North Ridge Estates is to restore the site to productive use as a residential neighborhood for the Klamath Falls community. Following the successful remediation of asbestos contamination and health risk reduction, site restoration, and home restoration, homes and vacant properties will be available for sale. Properties where asbestos remains below the ground will have a notation on the deed to ensure that the remedy continues to protect people and the environment.
In 2018, EPA completed the removal and cleanup of asbestos-contaminated materials and soils at the site. The 17 restored home properties at the site will be available for sale, with three homes listed for sale in 2018.North Ridge Estates Site Redevelopment Profile (3 pgs, pdf) September 2018
Economic Activity at the Site
As of December 2018, EPA did not have economic data related to on-site businesses, or economic data were not applicable due to site use. View information about redevelopment economics at Superfund sites.
Renewable Energy at the Site
- Minimize total energy use and maximize use of renewable energy.
- Minimize air pollutants and greenhouse gas emissions.
- Minimize water use and impacts to water resources.
- Reduce, reuse, and recycle materials and waste.
- Protect land and ecosystems.
Activity and Use Limitations
At this site, activity and use limitations that EPA calls institutional controls are in place. Institutional controls play an important role in site remedies because they reduce exposure to contamination by limiting land or resource use. They also guide human behavior. For instance, zoning restrictions prevent land uses – such as residential uses – that are not consistent with the level of cleanup. For more background, see Institutional Controls.
Engineering and Institutional Controls
Engineering Controls are physical measures that help reduce or eliminate exposure to remaining contamination. Institutional Controls are legal controls that help minimize potential for exposure to contamination by restricting land use and/or by providing information. Both controls are in place at North Ridge Estates.
The Engineering Control is the protective clean soil cap present over the entire neighborhood. Multiple types of materials were used as protective caps including a minimum two-foot layer of clean soil with vegetation, asphalt and concrete surfaces, large rock surfaces, and liners installed below covered porches and in crawlspaces.
The Institutional Controls are easement and deed restrictions on every excavated property and notices of environmental contamination on Thicket Court properties with underground asbestos steam pipe. Property owners are required to maintain the protective caps present on their property. This includes ensuring vegetation on the soil cap is healthy and maintained to prevent erosion, drainage on the property is maintained to prevent the soil cap from eroding, asphalt and concrete surfaces are kept in good repair, and geotextile liners in crawlspaces and under porches are undisturbed. Property owners are also required to maintain any stormwater features location on the property to preserve stormwater conveyance capacity. Stormwater features include culverts, surface channels, and other miscellaneous features such as inlet structures. Property owners cannot alter, impede, or restrict the flow of stormwater conveyed by these features through the property.
