Rain Gardens

What is low impact development

 ?
There are many techniques and design considerations that help capture and move rain water while improving the aesthetics of your property. Low impact development manages the rainwater that falls on your property by allowing some to evaporate back into the air, some to absorb into the ground, some to be captured and used later as needed, and the rest to slowly pass into the stormwater system and into nearby streams. 

Demonstration rain garden project


The City partnered with the King County library system to provide a demonstration rain garden that captures and filters rain water from their pedestrian roof.  This particular design is meant to function in a high traffic area with minimal maintenance.  Feel free to drop by the library, read more about this garden, and grab a booklet inside the library to learn more.
