     The Cycle of Water
 Rain         Rain makes our
                gardens grow
               Unless there is too
                much rain and not
                enough sun
               Then our plants rot
                and crops mildew
     Rain is Stormwater
 Rain                According to the Washington
                        State Department of
 Stormwater            Transportation, for every
                        inch of rain that falls on an
                        acre of pavement, about
                        7,000 gallons of stormwater
                        is produced.

    Landscaping
    Resource management



               (McNeillan, & VanDerZanden, 2004; WSU, 2003)
   Increasing Permeability


 Practice low impact development
 –Make a plan

  – Non-native blackberries
 Plant and encourage native plants
  – Snowberry
  – Salal
