RE: Creekside As -Built WP0201200062 — Comment Response
Dear Mr. Anderson,
Thank you for your review of the Creekside As -Built Plans, WPO201200062. We have revised the plans per your
most recent comments emailed on September 29", 2022. Please find below a summary of your comments and a
detailed response to each.
1. Design provides larger stored volume between low and mid flow orifices (4') than as -built condition
(3.2F), based on orifice elevations. Please provide routings that indicate less actual stored volume
between low and mid -flow orifices does not negatively impact detention or peak release rate during the
10-yr event.
The as -built stormwater routings indicate that the as -built conditions of the pond meet the intent of
the SWM Plan and does not negatively impact the detention or peak release rates.
2. As -built drawing should include Northing-Easting coordinates.
The coordinates of the SWM facility primary spillway have been provided on the cover sheet and
the principal spillway callout.
3. As -built drawing should include SWM facility easement deed book and page reference.
The SWM facility easement deed book and page reference has been provided on the cover sheet.
4. PE certification for SWM facility is required.
The PE certification for the SWM facility has been provided with this submission.
5. Video of SWM Facility pipe outfall is required.
A pipe video of the SWM Facility primary spillway culvert has been provided with this submission.
