KC WTD Fall City Wastewater Project
An unincorporated rural town with a population of 1,933 (2010 U.S. Census), Fall City is located 26 miles east of Seattle along the Snoqualmie River near the confluence with the Raging River. The service area for this project is the FCBD, a 21.4-acre zoning overlay comprised of 62 parcels of mixed residential, commercial, and vacant properties. Half of the existing parcels are commercial, with the majority located along SE Redmond-Fall City Road. Sixteen single-family homes make up most of the 19 residential parcels, with multi-family residential housing on the other three parcels. Currently all wastewater produced in the FCBD is disposed of by individual on-site sewage systems, some of which are aging, and some are of which are too small or lack capacity to support their own on-site septic system (OSS) given auxiliary drain field and separation requirements. Some septic tanks drain directly through sandy soils into the Snoqualmie River without the treatment provided by an appropriately configured drain field. As of February 2016, King County Public Health estimated that only 14 systems of the 50 parcels with permanent structures were “approved” systems. The lack of adequate wastewater infrastructure limits residents’ ability to develop and use their properties and comprises a significant public health and environmental hazard.
