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. Amanda Jones Wetlands & Environmental Planning Group Leonard S.

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) 2-6 Table 2-2 ;Rainfall Intensities - Charlotte, North Carolina (continued) OF variables for equation: Intensity (1) - �_w (t +b) (2.1) t = duration of rainfall (minutes - min) I = intensity (inchesthour - in/hr) a, b, n = storm facing parameters a 44.7516 61.3997 83.3331 97.3148 104.2990 118.4790 b 10 12 15 15 15 15 n 0.8070 0.8035 0.8256 0.8254 0.8179 0.8223 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.

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.
