Water runoff from Spring Street is an issue.

It's complicated.  The ash trees used to take up lots of water into their leaves.  More development along Spring Street increased the amount of runoff, and the amount of pollution -- like oil and decaying trash.

Now reed canary grass and phragmites keep the water from sinking into the ground (infiltrating:) as well.

Let's redirect the water!  Not easy.

The center of lower Colonial is almost flat -- a "flowage" with no clear channel. By putting down some left over tree trunks the water will spread out onto a large area.  Then it can soak into the ground where natural microbes will clean it up.

When it finally gets to the river, the water will be much cleaner and the salmon fingerlings will do much better.

Some ducks loved the new water flow from the day after the City moved some logs.  (Thank you again PRCS!)

Why worry abut a little water?

The Spring Street runoff gets all the way over to the River path.  Even in the winter it runs out and makes an ice sheet.  Hard to walk through.  In summer, it has washed out the River path a few times.
