During review of the above noted application, it was found that the following information, corrections, or
clarifications are needed. Please redline plans or submit three (3) sets of revised plans/documents with a
written response to each of the items below to a Permit Coordinator. Theresa Umbaugh is your City
contact for this project.
1.A drainage report was submitted, but did not include drainage calculations. The detention system is stated
to be sized for 10,900sf of impervious area which would require design and calcs by a licensed engineer.
Upon submittal of this information, the storm system design will be reviewed by Blaine Chesterfield, Storm
Water Program Manager.
2.It is understood from the drainage report that the asphalt areas (including the path) will add approximately
10,900 sf of impervious area. An equivalent area from the parking lot will be detained in lieu of detaining
the area from the new path. Please confirm the amount of parking lot impervious area in which storm water
flows will be directed to the new detention system.
3.Please provide RIM and invert elevations for the detention system and the oil/water separator on the
drainage plan.
4.The detention system shall be designed to include an upstream manhole to allow for access and maintenance
of the detention system.
5.Please callout the requirement for polypropylene steps in the detention manhole.
6.The existing outfall line from the CB in the parking lot will be intercepted and routed to the detention
system. Please confirm that the detention pipe will be prefabricated to allow for this inlet pipe. Also, please
identify the existing storm pipe material and the type of connection (fitting) required to connect this pipe to
the detention system.
7.Call out the requirement to abandon the existing 8 outfall line from the CB in the parking lot to the CB in
the gutterline on Viewland Way.
