The Loree Estates subdivision was constructed in the late 1970s. Over time, the stormwater outfall located between 20014 and 20028 SE 19th Street fell into disrepair and eroded into a tributary stream to Kanim Creek. The City temporarily stabilized the area with the addition of large rock. The Sammamish City Council adopted the 2019-2020 Biennial Budget, which includes funding for this project to install a tightline in the existing outfall location to prevent further erosion.
