Progress report on greenway--Nov. 7, 2010



Since my last report:
  • The gravel road had been extended from Owen Dr. down almost to the west end of the greenway (see above).
  • Most of the tree cutting has been finished.  A small group at the west end remains to be cut.
  • Some of the small tree roots have been cut off cleanly.
  • The pile of soil at the west end has been better protected.
  • Tree 128 was cut.  This was one of the trees outside the construction area.  The City says it was cut because it was damaged by wind, and likely to die.
  • Tree 39, which cost a resident $800 to plant, had a stake driven among its roots very close to the trunk.  Update 11/9: A city forestry expert looked at the tree, and said it had not been seriously damaged.  Rootlets regrow quickly, if less than 30% are damaged.


Problems found on this inspection:
  • A large root of a protected tree has been laid bare (but not cut).  It needs marking and protection.  Some other small roots appear to have been ripped out, and are not cleanly cut.
  • The western end of the ravine is bare soil and needs stabilization with gravel (see above).
  • In the sediment trap, two Jersey barriers are not connected to the others with metal pins.  Hence they could move during a flood, making the sediment trap ineffective.

  1. looks like this project needed to be done, you could see how bad the erosion was. man-holes sticking out of the ground and big trees being under-mined. how much rain water was going into the sanitary sewer? a couple more storms and the sewer main would have been blown apart and sewer water would be everywhere! try to contain that.

  2. You're right, the project did need to be done--both for erosion and to fix the sewer. We just wanted to make sure that more erosion wasn't caused during construction, than 10 or 20 years of keeping it as it was.
