IV. PROJECT INFORMATION

Stormwater runoff will travel through ditches and swales, enter inlets and pipes, and travel to wet
ponds /detention BMP's for treatment and release.
2. a. If claiming vested rights, identify the supporting documents provided and the date they were approved:
❑ Approval of a Site Specific Development Plan or PUD Approval Date:
❑ Valid Building Permit Issued Date:
❑ Other: Date:
b. If claiming vested rights, identify the regulation(s) the project has been designed in accordance with:
❑ Coastal SW —1995 ❑ Ph II — Post Construction

SCM Narrative
Project Description
The Heritage subdivision project is a multi -phase project. Phase I consists of approximately138
acres located at Hawfield Road, in Indian Trail and Wesley Chapel, NC. The total disturbed area
is approximately 102 acres. The subject property is an existing undeveloped parcel bound to the
west by Wesley Chapel road, and divided by the jurisdiction boundary between the municipalities
of Indian Trail and Wesley Chapel. Proposed construction/demolition consists of the construction
of new subdivision roads, 364 residiential lots and houses, an amenity center and open area, lane
widening of part of the existing Wesley Chapel Road, and stormwater wet ponds/detention
basins. Surrounding adjacent properties are primarily residential neighborhoods.
Figure 1 —Vicinity Map
Stormwater control measures
The overall tracts of land is mostly undeveloped and is wooded or meadow condition. The site
generally drains from the north to the south into Price Mill Creek. The site drainage is a mix of
underground piping and surface ditches/swales. A stormwater model was created to show pre -
development flows leaving the project area. A post -development model was also created to show
the amount of detention necessary to meet pre -development rates for the 1 -yr., 10 yr. storms
(minimum) and safely pass the 25 yr., and 100 yr. storm. See attached Hydrocad model output.
The system chosen is composed of two wet ponds/detention basins that combine both water
quality treatment and detention to meet the pre -development rate of run-off. See detail C910 &
C911 in the attached plan set. The "water quality" volume was also calculated, see attached. The
wet detention basins were sized to reduce the nitrogen levels leaving the project area to less than
6 Ib/ac/yr. The remainder will be bought down to the state limit of 3.6 Ib/ac/yr. See attached
worksheet.
Soils
According to the United States Department of Agriculture (USDA) Soil Survey, there are multiple
soil types within the project limits. Please refer to the attached soil survey and map for details.

Wet Detention Pond Maintenance Requirements
The wet detention basin system is defined as the wet detention basin, pretreatment including forebays and the vegetated filter if
one is provided.
Important maintenance procedures:
_ Immediately after the wet detention basin is established, the plants on the vegetated shelf and perimeter of the
basin should be watered twice weekly if needed, until the plants become established (commonly six weeks).
_ No portion of the wet detention pond should be fertilized after the first initial fertilization that is required to
establish the plants on the vegetated shelf.
_ Stable groundcover should be maintained in the drainage area to reduce the sediment load to the wet detention
basin.
_ If the basin must be drained for an emergency or to perform maintenance, the flushing of sediment through the
emergency drain should be minimized to the maximum extent practical.
- Once a year, a dam safety expert should inspect the embankment.
After the wet detention pond is established, it should be inspected once a month and within 24 hours after every storm event
greater than 1.0 inches (or 1.5 inches if in a Coastal County). Records of operation and maintenance should be kept in a
known set location and must be available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall be repaired immediately.

1 Precipitation frequency (PF) estimates in this table are based on frequency analysis of partial duration series (PDS).
Numbers in parenthesis are PF estimates at lower and upper bounds of the 90% confidence interval. The probability that precipitation frequency estimates (for a
given duration and average recurrence interval) will be greater than the upper bound (or less than the lower bound) is 5%. Estimates at upper bounds are not
checked against probable maximum precipitation (PMP) estimates and may be higher than currently valid PMP values.
Please refer to NOAA Atlas 14 document for more information.

This product is generated from the USDA-NRCS certified data as
of the version date(s) listed below.
Soil Survey Area: Union County, North Carolina
Survey Area Data: Version 16, Sep 20, 2016
Soil map units are labeled (as space allows) for map scales
1:50,000 or larger.
Date(s) aerial images were photographed: Feb 11, 2011—Feb
13, 2011
The orthophoto or other base map on which the soil lines were
compiled and digitized probably differs from the background
imagery displayed on these maps. As a result, some minor
shifting of map unit boundaries may be evident.
