Culvert Replacements
Culvert Replacement
The 2009 Flood Reduction Planning Study identified public 14 culverts that have varying degrees of capacity deficiency. The City intends to replace these culverts over the next 12 years. The planning level estimate for the replacement of all of the culverts is $3,715,000 in 2009 dollars.

Rain Garden
It is critical that stormwater entering Lyon Creek and McAleer Creek in pipes be reduced over the next 50-100 years. To accomplish this the City has done the following:
  • Adopted the most recent version of the King County Surface Water Design Manual.
  • Provides Environmental Mini-Grants for private property owners to install low impact development (LID) facilities on their property (rain gardens, green roofs and pervious driveways/walkways/patios). This allows rainwater to enter the ground rather than go into a pipe that leads directly to a stream.
  • Encouraged the use of LID in new development/redevelopment with 
  • Participated in the Lake Ballinger/McAleer Creek Forum, an inter-jurisdictional group that seeks to reduce flooding and improve water quality on McAleer Creek. The jurisdictions that have participated include Edmonds, Mountlake Terrace, Lake Forest Park, Shoreline, Snohomish County, Shoreline and Lynnwood. 
  • Complied with the NPDES water quality permit

Other opportunities include, but are not limited to, using low impact development techniques on City capital projects, installation of a demonstration rain garden at the City Hall, adoption of the newest low impact development manual and coordination with the neighboring jurisdictions on Lyon Creek.
