INTRODUCTION
The proposed Howard /Emerson Tract development is located at the intersection of Morrisville
Parkway and White Oak Church Road in Cary, NC. The proposed development is a low - density
residential development.
The site in its existing conditions is approximately 80% wooded with some open space and
impervious area. White Oak Church Road divides the site; it is a ridge which diverts stormwater
runoff to 2 analysis points for this study. The site is comprised of HSG "D" soils. A soils map
is provided in the Background Data portion of this report.
PLANNED EROSION AND SEDIMENTATION CONTROL PRACTICES
1. TEMPORARY GRAVEL CONSTRUCTION ENTRANCE /EXIT
A temporary gravel construction entrance /exit will be installed at the entrance
drive to the site to provide a buffer area for construction vehicles to drop their
mud and sediment to avoid transporting it onto public roads.
2. SILT FENCE
Silt fence will be installed in areas of fill around the perimeter of the site to
maintain drainage into temporary diversion ditches. Silt fence will be used in
natural outfall areas to prevent any sediment from leaving the site.
3. TEMPORARY DIVERSION DITCH
Temporary diversion ditches will be provided to protect work areas from upslope
runoff, and to divert sediment -laden water to appropriate traps or stable outlets.
4. PERMANENT DIVERSIONS
Permanent diversion swales will be provided to divert water from areas where it is
in excess to locations where it can be used or released without erosion or flood
damage.
5. TEMPORARY SKIMMER SEDIMENT BASIN
A temporary skimmer sediment basins will be installed at the project site to retain
sediment on the construction site, and prevent sedimentation in the surrounding
area.
MAINTENANCE CONSIDERATIONS
The homeowner association shall be responsible for periodic inspection and
maintenance of all temporary erosion control measures and permanent stormwater
devices. Any measure that fails to function as intended shall be repaired immediately.

HOWARD /EMERSON TRACT
NORTHWEST COMMUNUNITY CHURCH - RESIDENTIAL
STORMWATER MANAGEMENT REPORT
CARY, NORTH CAROLINA
INTRODUCTION
The proposed Howard /Emerson Tract development is located at the intersection of Morrisville
Parkway and White Oak Church Road in Cary, NC. The proposed development is a low- density
residential development.
The site in its existing conditions is approximately 80% wooded with some open space and
impervious area. White Oak Church Road divides the site; it is a ridge which diverts stormwater runoff
to 2 analysis points for this study. The site is comprised of HSG "D" soils. A soils map is provided in
the Background Data portion of this report.
The impacts of the increased runoff from the development will be mitigated with one wet pond and
one stormwaterwetland.
Site outlined in blue.
STORMWATER MANAGEMENT REQUIREMENTS
The proposed development is with the Jordan Lake, Lower New Hope watershed. The site must
therefore meet Town requirements relating to town wide ordinances and policies for stormwater
compliance. To meet these requirements the Nitrogen export rates from the site are to be reduced to
4.4 lbs /ac /yr; Phosphorus export rates to 0.78 lbs /ac /yr.

STORMWATER MANAGEMENT REPORT

This is accomplished through the use of one wet pond and one stormwater wetland. Additionally,
peak flows at the point of analysis shall be reduced to predevelopment levels for the 1 -year storm and
larger storms must also be controlled to within the anticipated flows from R -40 zoning or 1o% of
predevelopment flows, whichever is less.
METHODOLOGY
The stormwater study was conducted using the natural drainage features as depicted by LIDAR
topography and existing field surveys. Proposed drainage areas were based on field survey data and
proposed development within the drainage areas.
The scope of work included the following analyses:
Hydrology
❑ Simulation of the 1 -year, 2 -year, 5 -year, 10 -year, and loo -year rainfall events for the Cary,
NC area
❑ Formulation of the 1 -year, 2 -year, 5 -year, 10 -year, and loo -year flood hydrographs for the
pre- and post- development drainage areas
Hydraulic
❑ Routing the 1 -year, 2 -year, 5 -year, 10 -year, and loo -year flood hydrographs for
predevelopment runoff from the site.
❑ Routing the 1 -year, 2 -year, 5 -year, 10 -year, and loo -year flood hydrographs for post -
development runoff through the stormwater BMPs.
❑ Analyzing results at the analysis point
The results of the hydrology calculations are used in the hydraulic analyses. The hydraulic design
requires the development of stage- storage and stage- discharge functions for the BMPs. The
rainfall /runoff hydrographs, stage- storage, and stage - discharge functions have been compiled to
create a computer routing simulation model using Bentley Systems PondPack v1o.o software. This
PondPack model was then used to assess the peak water surface elevations in the BMPs forthe design
rainfall events. The PondPack modeling results are provided as appendices to this report.
HYDROLOGY
The SCS Method, in conjunction with NOAA Atlas 14 rainfall data for Raleigh- Durham International
Airport, was used to develop runoff hydrographs for the storm events. This method requires three
basic parameters: a curve number (CN), time of concentration (Q, and drainage area.
Curve numbers were based on soil type and land use. Soil types were delineated from the Soil Survey
of Wake County, North Carolina (November 1970). The curve numbers used in this study are listed in
the PondPack section of this report.
Time of concentration for pre- and post - development drainage areas were developed using the TR -55
method. A minimum time of concentration of 5 minutes was used for the proposed piped drainage
systems.

HYDRAULICS
Computer simulated reservoir routing of the 1 -year, 2 -year, 5 -year, io -year, and loo -year design storms
utilized stage- storage and stage- discharge functions. Stage - storage functions were derived from the
proposed geometry of the BMPs. A non - linear regression relation for surface area versus elevation
was derived for each BMP. This relation estimates the incremental volume of the basin to the stage or
elevation of the basin. Stage - discharge functions were developed to size the proposed outlet
structures for the BMPs.
NITROGEN EXPORT
The Nitrogen and Phosphorus export rates for the development were calculated using Jordan/ Falls
Lake Stormwater Nutrient Load Accounting Tool. All onsite drainage areas, including roadway and
driveway improvements, were used in the nutrient export analysis. The worksheet used to calculate
the nutrient export loading rate can be found in the appendices.
CONCLUSIONS
Quality
Based upon the routing study, the proposed stormwater management plan has sufficient measures
to provide the necessary removal of nutrients as required by Town policy.
The proposed stormwater BMPs have been designed to store and treat the water quality volume
(runoff associated with the first 1" of rainfall, WQv) generated by the contributing drainage area, and
draw down that volume in at least 2 days, but no slower than 5 days.
Because the runoff resulting from the first 1" of rainfall is being discharged per the NCDENR standards
for a wet pond and a stormwater wetland, the appropriate reduction credits were taken for the area
draining through the BMPs. The BMP treatment resulted in bringing the total site's Nitrogen and
Phosphorus export down to below target levels.
Quantity
The peak flows from the site have been attenuated for predevelopment levels. Furthermore, the
proposed BMPs have sufficient storage to safely pass the Zoo -year storm event without overtopping.
