Re: The Townes at Bermuda Run Phase 1 (SW 4231202)
Dear Brianna:
I would like to request a variance/waiver for a small portion of BUA (approximately 3%
of the total BUA)that we cannot drain to one of our proposed SCM devices. This portion
of BUA is associated with the entrance drive and the sidewalks on both sides of the
entrance drive. The Town of Bermuda Run requires that we install both Curb and Gutter
and sidewalk for this entrance drive.NCDOT and the Town of Bermuda Run have also
locked this driveway connection point to Hwy 158 based on their master development
plan for this area and an approved driveway permit has been issued for this location.
The other constraint is there is a drainage feature and associated wetlands that runs
parallel with Hwy 158 and extends into our property approximately 80'. Which again
limits the area to provide a SCM in this environmentally sensitive area. However,the
small percentage of BUA not being treated does meander through a natural vegetated
area for over 700' before entering Smith Creek.
The current stormwater requirement is for the treatment of the first 1"of runoff from the
BUA to be treated in an approved SCM device. Our proposed equal or better
performance is to capture the first 2" of runoff on the remaining 97% of the proposed
BUA. We feel by doing this we have far exceeded the intent of the stormwater
requirements and the net result looking at the project as a whole provides much more
quality control than if we were to treat 100%of the BUA at the required first 1"of
runoff.
Thank you again for your consideration in the matter and look forward to hearing from
you.

Re: The Townes at Bermuda Run—Phase 1
Dear Jim:
This is a brief narrative for the above project located along US Hwy 158 in Bermuda
Run. This property is being developed as a multi-family subdivision(with 73 Townhome
Units). The developer of this property is going to be Henson Realty,LLC. The property
contains 23.52 acres that will be developed for Phase 1. It is located in the Yadkin Pee-
Dee River Basin and the receiving water course is Smith Creek(index# 12-93-1). This
project is not in a water supply watershed. It is,however, located in an area that has to
comply with Phase II Stormwater program issued by DEMLR. The purpose of this plan is
to show the overall watershed plan for the property and the full design plans for the wet
detention ponds (2-Wet Detention Ponds). See plans for all stormwater and pond
calculations. The site currently has no existing BUA on the site, and all of the proposed
BUA is required to be treated in the wet detention ponds to the extent possible.
Stormwater runoff from the entire wet detention ponds' drainage basin will be conveyed
to the wet detention ponds via a network of storm sewer pipes that will be designed and
installed per NCDOT standards and specifications. The storm pipe network will enter the
ponds at an elevation equal to the permanent pool elevation. The wet detention ponds
have been designed per the state stormwater design manual with no modifications
requested.
Sincerely,
