See below for responses to your comments in red.

I have also attached an updated PCN reflecting the revisions, a narrative describing he impacts, the wetland/stream
delineation report prepared by ECS, and an update plan set highlighting the streams/impact areas, etc.

Please review and let us know if you need any additional information.

Subject: Park 1764 project, DWR 18-0195

The purpose of the project is the Park 1764 business development. This should be part of the application. We noted
that the sewer line extension would serve the Park 1764 in Section 3E. Please clarify if you would like that notation
made in other sections.

Wetland impacts are permanent and temporary. That area that remains within the maintained easement is consider a
permanent impact. Area outside the permanent will be considered temporary and should be restored. Restoration
information should be clarified The PCN has been revised to note the temporary and the permanent impacts as
noted above. The plans have been noted to reflect this also. (See attached)

Stream impacts are confusing. The line runs parallel to the stream (that I can tell), except for one crossing. Please
clarify. See attached pdf set with the streams/wetlands highlighted. We have also attached the delineation report
for your reference of the overall area. The sewer line construction area should be 10 ft or greater from top of
bank. Typically the limits of disturbance is a minimum of 25’ from top of creek bank where it parallels the main
stream. If general bank stabilization is proposed (rather than stream crossing), this should be clarified on the plan view
and length of stream bank. I am sure you are not excavating 40 ft of stream. The open cut to install the sewer line
under the stream bed would be no wider than 5’ - we have accounted for the temporary pipe crossing to get
equipment across the stream and the pump around area – allowing 40 total lf of temp impact for each crossing. The
open cut and the area of pump around should be separated or clarified within the application

Thanks
