Natural Treatment Site: Forge
The Forge NTS site is located along Portola Road in the foothills north of Irvine. The site is surrounded by urban development and agricultural land uses. It has yet to receive sufficient flows to warrant regular water quality monitoring. The basin vegetation has filled in well and presents a good mixture of upland and wetland species. It is anticipated that this site will soon require regular water quality monitoring.
