RE: [External] Uwharrie Middle School
Keith,
Please provide the following items to document that the project will not cause degradation of downstream surface
waters:
1) Delineation of each drainage area and accompanying calculations to show that flows from every discharge point
will be non-erosive to both the land surface and the receiving surface water during the peak flow from the 10 -
year storm event.
2) Calculations to demonstrate that for any discharge points proposed to increase flow rates and volume, the
structural stability of the receiving surface water will not be compromised.
3) Designed drawings (both aerial and profile views showing the actual designed dimensions) and calculations of
any proposed detention system (i.e. level spreaders). Any vegetated conveyances should also be depicted on the
drawings.
Let me know if you have more questions. Thank you!

Ms. McDaniel:
Got your call. I will be more than happy to provide whatever is needed to show that this site qualifies as a Low Impact
Development. I just need more specifics about what you are looking for. It is difficult to decipher when the regulations
are so broad. Thanks.
