Chris,
With regards to this project I have a couple questions/concerns about the submittal that we received on May 30, 2018:
When you use the term "near perpendicular" you mean outside of the 75-105 degree angle required by the General
Certification, correct? In other worlds that's where they need an exception to that requirement?
You note that a perpendicular tie-in coming from the west ties into the corridor at station 38+60 and that it will cross
Stream SA. Then you note that the location and impacts are subject to change. When I issue a 401 approval it explicitly
states that it is for the plans/designs submitted. So, they either figure this out now for certain or they would be out of
compliance in the future if it isn't in the location proposed, or take it off this submittal and seek approval for that
crossing in a subsequent permit.
With regards to Branch 4B St. 4+00 through 12+00, you indicate that they cannot increase the distance between the
corridor and the parallel stream due to constraints of housing and topography, which I understand. My experience with
these types of situations is that it is very difficult for the contractor to excavate a trench, remove/stock pile the excess
soil, have accessibility for line installation/equipment and restore the area without the need for streambank disturbance
from vegetation clearing and/or equipment access. I will be requiring temporary dewatering of the parallel channel in
this area. They would have to dewater immediately adjacent to their work area each day. Also they will have to
stabilize the site at the end of each work day and not open more than they can construct in a day. I'll also require a pre -
construction meeting. Can you please discuss this with the engineer and applicant and make sure they understand the
additional requirements that I propose and if we need to talk about it in more detail prior to permit issuance we
can. Also, can you verify that DEMLR will approve an erosion control plan for this area? They have a standard 15' buffer
requirement to all streams.
Thanks,
