This is for 17-0016, low density development. They need to meet Huntersville’s SW reg, but since it was LD, I think they were
good to go, without the designed grass swales.

One outfall towards a non JD pond, then one at the rear of the development and one at the top…

Thanks

Alan,

Attached are the revised plans from the engineer showing the storm water outfall pipes shortened with engineered grass
swales. Let me know if you think you'll need anything else to issue the 401.

Amanda,
Please find revised Blackwood plans, we have also attached the requested ditch line calculations. Let us know if
anything else is required at this time.

Thanks,

Let's try that first... add any calculations as needed.

Thanks Len. We are in the process of making the revisions, we should be able to have these done in the next few
days. Should we just email revised plans to you and Amanda?

Nick and Chris... this is a comment from the NCDWR reviewer. I know Nate and Drew would like this project to move forward pretty quickly.
Please respond as soon as possible. Thanks. Len

"Will need to place on hold, till we get the storm water issue straighten out. The grass swales, per the regs. They need to meet guidelines. I
think you can meet this given the width of buffer and open area".

Chris,

Just wanted to follow up on my call yesterday. Attached are the notes from our discussion with DWR during
yesterday's review with regards to shortening/re-aligning storm water outfalls in lieu of providing bmps/treatment.
If the plan can be modified, then this should resolve any concerns that is holding up the 401.

2.4 RATIONAL METHOD
2.4.1 Introductlon
When rising the rational method some precautions should be considered.
• In determining the C value (land use) for the drainage area, hydrologic analysis should
take into account future land use changes. Drainage facilities shall be designed for future
land use conditions as specified in the County and City Land Use Plans and Zoning Maps
(or existing land use, whichever generates the higher runoff rate).
• Since the rational method uses a composite C value for the entire drainage area, if the
distribution of land uses within the drainage basin will affect the results of hydrologic
analysis, then the basin should be divided into two or more sub -drainage basins for
analysis.
• The charts, graphs, and tables included in this section are given to assist the engineer in
applying the rational method. The engineer should use good engineering judgment in
applying these design aids and should make appropriate adjustments when specific site
characteristics dictate that these adjustments are appropriate.
2.4.2 Runoff Equation
The rational formula estimates the peak rate of runoff at any location in a watershed as a function
of the drainage area, runoff coefficient, frequency factor, and mean rainfall intensity for a
duration equal to the time of concentration (the time required for water to flow from the most
remote point of the basin to the location being analyzed). The rational formula is expressed as
follows:
^--> Q = CCU (2.2)
Where: Q = maximum rate of runoff (cubic feet/second - cfs)
C = runoff coefficient representing a ratio of runoff to rainfall
I = average rainfall intensity for a duration equal to the time of
concentration (in/hr)

approved by the City/County Engineering Departments. Note: time of concentration cannot be
less than 5 minutes.
A common error should be avoided when calculating 1'. In some cases runoff from a portion of
the drainage area which is highly impervious may result in a greater peak discharge than would
occur if the entire area were considered. In these cases, adjustments can be made to the drainage
area by disregarding those areas where flow time is too slow to add to the peak discharge.
2.4.4 Rainfall Intensity
The rainfall intensity (1) is the average rainfall rate in inches/hour for a duration equal to the time.
of concentration for a selected return period. Once a particular return period has been selected for
design and a time of concentration calculated for the drainage area, the rainfall intensity can be
determined from Rainfall -Intensity -Duration data given in Table 2-2. Straight-line interpolation
can be used to obtain rainfall intensity values for storm durations between the values given in
Table 2-2.
2.4.5 Runoff Coefficient
The runoff coefficient (C) is the variable of the rational method least susceptible to precise
determination and requires judgment and understanding on the part of the design engineer. While
engineering judgment will always be required in the selection of runoff coefficients, typical
coefficients represent the integrated effects of many drainage basin parameters. Table 24 gives
the recommended runoff coefficients for the Rational Method.
