Hello Alan,
Thank you for returning my call this morning. As discussed there are some stream crossing along the ROW for the Steele
Creek Pump Station Replacement Project which have significant amounts of rock or boulders in the banks and their
presence significantly hinder the proper installation of erosion control matting. If we proceed with the existing plans we
will have to move a machine in to these areas that are completely saturated due to 6 weeks of rain, to dig the rock out.
If we dig the rock out of the banks to make them smooth enough to mat that act will destabilize the now stable banks. If
we try to mat and don't remove the rocks and boulders we will not be able to get good ground contact which leaves the
banks susceptible to increase erosion from the flapping matting and eddies forming behind it. Not to mention the first
good rain will likely rip the loose matting off the banks.
Therefore for the areas that are not suited for the proper installation of mat we propose to install livestakes at 18 inches
on center effectively doubling the stem counts and adding additional trees and shrubs on the upper banks. A list of the
crossings is attached; matting or not matting is noted along with stems counts.
Would you kindly respond to this email to the affirmative if you concur with our assessment and revised plan?
Respectfully submitted,
Karri

We are in agreement with you — please proceed using your best judgement, and ability to obtain concurrence with the
revised approach from the regulatory agencies.
We will need updated record drawings depending upon the restoration method ultimately agreed upon at each location.
