Project: Westgate Elementary School Relocatable Classrooms
Application Nos. bld20160332 and bld20160333
AHBL No. 2150864.14
Subject: Response to Comments dated May 6, 2016
Dear Ms. McConnell:
This letter is in response to your comments dated May 6, 2016, regarding the above
referenced project. The comments are included below (verbatim) for your reference. Our
responses are shown in bold after each comment.
Review Comments:
The detention system control structure manhole has an invert elevation of 379.71. The
existing storm drain CB upstream of CB#3 indicates invert elevations at 379.75. As
proposed, should the main line system back up it will flow into the proposed detention
system. Please revise plans accordingly.
Response: We are not aware of any capacity constraints within the existing
system. We have raised the proposed detention system's control structure invert
elevation to 380.13 to alleviate any potential concerns.
In the Introduction to the Stormwater Site plan prepared by AHBL and dated March
2016, it is noted that the subject project will meet the Minor Site Project requirements.
The project site classification is later correctly noted as a Category 1 small site. Please
revise the Introduction to correctly state the project classification, or alternatively I could
redline this change.
Response: Please redline the Introduction to the Stormwater Site plan to read
Category 1 small site.
In addition to addressing the above comments, we have also updated the civil permit plans to
be consistent with the architectural plans by showing both portable classrooms to be
constructed. If you have any questions, please call me at (206) 267-2425.
Sincerely,
Lauren Lovatt
Project Engineer
