5. 
Storm drain systems shall have access by means of drop inlets and/or manholes spaced at intervals not to exceed five hundred feet.
E. 
Stormwater quality. All applicable projects shall treat storm water runoff to reduce suspended solids. The treatment shall be equal to that obtainable by the detention of the twenty-four-hour design storm runoff. In addition to the requisite analyses, site design, and treatment methods to be incorporated into specific development project types identified in Chapter 17.84B, the design storm for treatment facilities shall be the "eighty-fifth percentile twenty-four-hour storm" for volume based designs and the "eighty-fifth percentile one-hour storm" for flow based designs. Surface water runoff shall be determined using the "Rational Method" with runoff coefficients and rainfall intensities as set forth below.
1. 
The runoff formula shall be:
Q = CiA
where
Q = flow (cubic feet/second)
C = runoff coefficient (dimensionless)
I = rainfall intensity (inches/hour)
A = contributing area
2. 
The following shall be used as the runoff coefficient (C) in the design of drainage facilities and structures:
a. 
For impervious areas (roofs, pavement, etc): 1.00
b. 
For pervious areas: 0.40
c. 
The rainfall intensity for a "ten-year storm" shall be determined from the following formula: log I = 0.83 -0.46(log t), where t = the time of concentration
d. 
The "twenty-five-year storm" is twenty-nine percent larger than the "ten-year storm" and the "one-hundred-year storm" is sixty-one percent larger than the "ten-year storm."
e. 
The time of concentration shall be determined by assuming that overland runoff travels at one foot/second on pervious surfaces and two feet/second on impervious surfaces. The runoff travel rate for flow in streets, storm drains, and other drainage structures shall be as determined by calculation.
f. 
For design of water quality related structures the "eighty-fifth percentile twenty-four-hour storm" shall be 0.130 inches and the "eighty-fifth percentile one-hour storm" shall be 0.2 inches with a factor of safety of two x, for a total of 0.259 inches.
