  •  Beavers are opportunistic (10+ / 0-)

    I expect to see their handiwork in the large restored sites that I mentioned, both of which are a few miles downstream from me.

    What amazes me, though, is that we see lodges and dams in the more densely urbanized area near my house.

    There is a major traffic arterial (state hwy) that follows the reaches of Fanno Cr. near my house. Both the highway and residential construction have pushed into the old flood plain, severely restricting the space that the stream can claim.  But even up here, the beavers periodically build dams and dens. Sometimes the water will raise concerns about the integrity of the highway or other nearby structures, and they'll take out the dams. But the beavers, apparently, don't feel permanently banished, because they continue to pop up in these spaces from time-to-time.

    Portland Bureau of Environmental Services does native plantings in the streamside areas, for both habitat and water quality purposes.

    The upper reaches of Fanno also have resident cutthroat trout. At one time, there were probably coho salmon in this reach as well, but there is a long culvert under a big commercial parking lot a mile or so downstream, and the coho can't make it up this far.

    •  rsmpdx, if we get to vote on it, I'd vote (9+ / 0-)

      for tearing up that parking lot, setting Fanno Creek free, and letting the salmon run the length of the Creek  up into the West Hills.

      •  I'm voting that way too, but (8+ / 0-)

        I'm guessing their are tremendous technical difficulties with doing that (along with added costs, of course).

        (Naivete alert! I am totally not a civil engineer.)

        For one, the stream has to cross under Beaverton-Hillsdale Highway (BHH), which, as you know, is a big, wide road. That will need a big salmon-friendly bridge or culvert. Fanno has to thread its way through the (primarily) commercial development surrounding the big three-way intersection of BHH, Scholls Ferry Rd. and Oleson Rd. (sometimes called "Kamikaze Corners").  Potentially that could involve the removal of some structures, such as the large bar/restaurant that has its front door almost in the stream.

        Kamikaze Corners needs to be totally re-engineered at some point, which would need to be coordinated with any Fanno daylighting project.

        I hope it can happen someday, and I will advocate for it, but I'm not holding my breath!
