What is a watershed?
all the streams, lakes and wetlands that rain drains to in an area

• Rain runs off quickly, not able to soak into the ground
• Rain washes over yards and streets, picking up non-point source pollution.
• Rain is piped directly to streams, or the wastewater treatment plant
In an urban watershed:

• Fertilizers and pesticides
• Animal waste (bacteria)
• Soap, oil, other car fluids
• Household hazardous wastes (oil, antifreeze, paint, etc)
• Soil (sediment)
• Volume (from rooftops, streets, etc. = impervious surfaces)
• Metals (copper, zinc) – harmful to salmon
Common stormwater pollutants

Too much volume, too fast

EVERYONE can do something to help!
• Reduce sources of pollution at home
• Capture and soak in runoff from impervious surfaces
• Plant a tree
• Share what you know
![Page 12: Stormwater Challenge: clean water practices for challenging sites, by Jamie Stamberger](https://reader035.vdocuments.us/reader035/viewer/2022070317/556983cbd8b42a32068b5374/html5/thumbnails/12.jpg)
• Reduce lawn size
• Use slow-release, organic or natural products, or no products!
• Avoid combined fertilizer and pesticide like “weed and feed”
• Landscape with native plants and low maintenance plants
1. Avoid or use fewer fertilizers and pesticides
![Page 13: Stormwater Challenge: clean water practices for challenging sites, by Jamie Stamberger](https://reader035.vdocuments.us/reader035/viewer/2022070317/556983cbd8b42a32068b5374/html5/thumbnails/13.jpg)
Reduce your need for pesticides
• Accept some imperfection • Plants can tolerate up to 50% defoliation
• Garden using IPM (Metro booklet)• Identify – metromastergardeners.org, 503–445–
4608• Manual control, biological, chemical as last resort
• Native and disease-resistant plants
• Right plant, right place • Take an EMSWCD naturescaping class, emswcd.org

Meadowscaping
• Replacing lawn or flower beds with native meadow mix, mostly forbs and grasses
• WMSWCD Urban Meadowscaping Program ([email protected]), Backyard Habitat Certification Program is a partner – audubonportland.org
• Planted often using plugs and seeds• One WMSWCD/BYHCP approved mix• Hobbs and Hopkins, Sunmark Seeds others

• Do not feed wildlife
2. Reduce bacteria entering streams

• Wash cars at a car wash
• Sweep driveway instead of washing
• Fix oil and gas leaks
• Clean up spills with kitty litter and put in garbage
3. Reduce car pollutants in streams

• Bring left over household hazardous waste to a Metro collection event or Swan
Island station.
• Paint• Cleaning chemicals• Pesticides

5. Plant a tree!
• Long-lived, large trees soak up a LOT of stormwater runoff
• Trees need sufficient space to grow (Maria will will touch on this more
in her presentation)
• Preserve trees on your property whenever possible
![Page 22: Stormwater Challenge: clean water practices for challenging sites, by Jamie Stamberger](https://reader035.vdocuments.us/reader035/viewer/2022070317/556983cbd8b42a32068b5374/html5/thumbnails/22.jpg)
Rain Gardens Downspout Disconnection
5. Soak up runoff at home, if safe
• Reduce volume of runoff heading to local streams
• Reduce lawn chemicals and bacteria in runoff
![Page 23: Stormwater Challenge: clean water practices for challenging sites, by Jamie Stamberger](https://reader035.vdocuments.us/reader035/viewer/2022070317/556983cbd8b42a32068b5374/html5/thumbnails/23.jpg)
Challenging sites!Wet soils, steep slopes and high ground water on your property?
Good news!
There are also practices that can be applied to these conditions to reduce runoff safely…
