Here in the Little Falls watershed, where every day we have more and more impervious surfaces being created with bigger houses replacing smaller, new roads and sidewalks being built to meet the growing demand for infrastructure and infill development creating new roofs and parking lots, stormwater run-off is probably the major contributor to the decline of the waterways.
The good news, Diane reported, is that governments are catching on to the idea that managing the water before it hits the streams is an important part of the solution to saving our creeks, rivers and bay.
Diane pointed to several key things that residents could do to improve the situation on their property - all having to do with redirecting the stormwater away from the impervious surfaces - be they driveways, sidewalks or streets - and into the ground.
The cheapest and easiest solution was to use flexible drain pipes (those 4" black hoses) to carry the water away from your house and into your yard. Diane pointed out that a shade tree during the growing season can actually absorb most of the water. Actually planting a little grove of trees to take this water was the best solution - especially if the trees are canopy trees like oaks or poplars.
Another solution was for residents to build rain gardens. The county has a rebate program which grants up to $1,200. (I think the county's goal is 30 percent of homeowners to have rain gardens) The idea of the garden is to divert the water from your roof directly to this special garden that will allow the water to soak into the ground. Below we have listed some landscapers who could help you get started.
Using porous pavers instead of asphalt and concrete is another way to cut down the run-off. The county also has a rebate program for this available for new construction or for retro-fitting.
Municipalities can also build rain gardens and divert stormwater away from the drains. Curb-cut gardens are becoming increasing popular. Check out the Green Street Program in Portland to see what one city is doing. Make sure you down load the Green Streets tour map . It has fabulous pictures of all the projects. We could do this in the Little Falls watershed. Contact, Sarah at stormwater@lfwa.org if you would like to coordinate an effort to convince the county to give us curb-cut parks.
A big thank you to Diane from us at LFWA. She has promised to get me her talk in PDF form. As soon as I get it, I'll post it.

I just designed a cool Rain Garden poster for a team of ten agencies in Oregon and Washington @ Good Nature Publishing.
We're staring work on a LID poster and a Green Roof poster, too.

PS: Maybe you know some agencies there that want to make some educational art to clean up storm water? Love to help.
