The scope of work included the following analyses:
Hydrology
? Simulation of the 2-year, 10-year, 50-year, and 100-year rainfall events for the
Raleigh, NC area
? Formulation of the 2-year, 10-year, 50-year, and 100-year flood hydrographs
for the pre- and post-development drainage areas
Hydraulic
o Routing the 2-year, 10-year, 50-year, and 100-year flood hydrographs for pre-
development runoff from the site.
o Routing the 2-year, 10-year, 50-year, and 100-year flood hydrographs for post-
development runoff through the proposed wet pond.
The results of the hydrology calculations are used in the hydraulic analyses. The
hydraulic design requires the development of a stage-storage and stage-discharge
function for the proposed impoundments. The rainfall/runoff hydrographs, stage-
storage and stage-discharge functions have been compiled to create a routing
computer simulation model using Haestad Methods PondPack vl0.0 software. This
PondPack model was then used to assess the peak water surface elevations for the
design rainfall events. The PondPack modeling results are provided as appendices to
this report.
HYDROLOGY
The SCS Method was used to develop runoff hydrographs for the 24-hour duration
rainfall curves using the NOAA Atlas 14 rainfall data for Raleigh-Durham International
Airport for the 2-year, 10-year, 50-year and 100-year storm events. This method requires
three basic parameters: a curve number (CN), time of concentration (tc), 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). Land use for existing
conditions was based on the most recent Wake County aerial photographs and field
observations. Post development land use is based on the proposed site plan. The
curve numbers used in this study are listed in the appendix of this report.
Times of concentration were calculated using methods described in the SCS
publication "Urban Hydrology for Small Watersheds, TR-55" and based on Wake County
topographic maps and field survey data. The post-development time of concentration
was calculated for the drainage areas that are piped to the storage area based on the
flow time through the piped drainage systems and small areas of sheet flow. The
breakdown of the time of concentrations and the calculated values are found in the
appendices of this report.

Stormwater Management Report April 2006
HYDRAULICS
Computer simulated reservoir routing of the 2-year, 10-year, 50-year, and 100-year
design storms utilized stage-storage and stage-discharge functions. Stage-storage
functions were derived from the proposed grading of each pond. A non-linear
regression relation for surface area versus elevation was derived for the basins. 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.
CONCLUSIONS
Based on the routing study, the proposed wet ponds have sufficient volume to safely
pass the 100-year storm. Where required for water wuality, the outlets were designed to
discharge the first 1 " of runoff through a separate outlet barrel and discharge that
runoff over a level spreader to provide sheet flow though the riparian buffer. Larger
storm events bypass the level spreader.

1-inch Runoff Volume Calculation
Using the runoff volume calculations in the 'Simple Method' as described by Schueler (1987)
Rv = 0.05 + 0.009(1) where, Rv = Runoff coefficient, in./in.
I = Percent impervious
Rv = 0.56 in./in.
Total runoff volume from 1-inch precipitation:
Runoff volume, S = (Design rainfall) (Rv) (Drainage Area)
S = 0.963 acre-ft
41934 cu. ft.
Storage Estimate from PondPack - Above Normal Pool
S= n/A cf
total depth = normal pool depth + storage required + 1 feet for 100-yr storm storage.
