As of October 2019
Phase: Design

We have started on work to reduce flooding along 25th Avenue NE near Ballinger Way NE. A plan for improvements was approved by City Council (see July 31, 2017, staff report):

  • Daylight the creek. Ballinger Creek runs through pipes along 25th Avenue NE from Brugger’s Bog Park to NE 195th Street. Daylighting will restore an open channel creek in this area.
  • Create flood storage in the City’s North Maintenance Facility (NMF) property.   
  • Replace the NE 195th Street Culvert. This culvert is outside of Shoreline but causes flooding in the City. We will work with the State and Lake Forest Park to get it replaced.

30% design plans were completed March 2019. Design should be completed by 2022. NMF floodplain construction should be done by 2023. Construction for other improvements is not scheduled yet. Funding for the work outside of Shoreline needs to be determined.

Right now we are working on: 

  • Advancing design.
  • Continuing discussions with interested groups. Such groups include neighbors, the general public, utilities, and local, state, and federal regulators and other groups.
  • Measuring Ballinger Creek flows (since December 2016).

Completed work includes:

Overview and History

This project was recommended as a high priority in the Lyon Creek Basin Plan. Our goal is to reduce flooding by improvements to Ballinger Creek, which is currently piped. The project area is along 25th Avenue NE between Brugger’s Bog Park and NE 195th Street.

Since 2001, neighbors and others have reported flooding at least 17 times. Flooding has impacted homes, buildings, yards, driveways, parking, and the 25th Avenue NE roadway and shoulders. Computer models have confirmed actual observations that this area floods about every two years. The most recent major flooding episode was on December 3, 2007, during an extreme storm event. Several smaller floods have happened since.

Flood plain storage in the City’s North Maintenance Facility (NMF) property will be planned by coordinating with the City Maintenance Facility Project.

Work is currently funded in part by a King County Flood Control District (KCFCD) Flood Reduction Grant as well as the KCFCD Sub-Regional Opportunity Fund.
