Sycamore Sewer
Sewer Image for Website.jpg

Overview
The City of Issaquah recently received numerous requests from residents to install sewer in the Sycamore neighborhood. Most on-site sewage systems in the neighborhood are past their useful lifespans. 

In addition, the topography of the Sycamore neighborhood is challenging for many homeowners to repair or replace their current on-site systems. The 20 lots along Issaquah Creek are located near wetlands and critical areas, which restricts the use of on-site sewage systems. The 45 lots on Squak Mountain are located on steep slopes and near small tributaries, both of which are not conducive for drain fields. 

History
The neighborhood plats are from the 1960s, and many still have the original on-site sewage systems in place. 

In 1996 and 1997, Seattle & King County health officials identified 23 of 58 septic systems in Sycamore to be in “pre-failure mode." Some property owners constructed new drain fields after those surveys. Others may still be utilizing systems that were in “pre-failure” mode in 1997.

City's Role
The Sycamore neighborhood has one of the greatest needs for sewer service in Issaquah.

Many Sycamore neighbors have asked the City to provide an overview of replacement options for these failing systems. The City’s current role is simply to educate your neighborhood on possible options moving forward. If the neighborhood wants to proceed with a public sewer system, then the City could act as a project manager.

Open House
