Low-Impact development (LID)
LID emphasizes practices which infiltrate stormwater (using proper safeguards to protect groundwater) on-site rather than collecting, conveying and discharging stormwater off-site.

Some exciting LID projects Mason CD has been working on:
Mason CD installed a permeable parking lot and an extensive rain garden at the new PUD 3 building on Johns Prairie Rd. in Shelton
This rain garden was installed in the Southside Elementary parking lot, with much help from volunteers, to prevent flooding and reduce stormwater runoff
