Remarks
Gary - In accordance with our telephone conversation on 3/25/87, I have revised
the bowstring analysis for areas #2, #3 and #4 to reflect a reduced outflow rate
of 0.24 cfs caused by concrete grate restriction. The grate used in area #1
will handle more inflow than the 0.3 cfs assumed in the original analysis. All
grates are adequate.
Sincerely,

Check capacity of Type "A" Drywel ls grates provlded. TWo tonfiourations f Rof a concrete grate were used (see attached sketch). Assume a head of
0.2 feet.

From figure 14 of the Drainage Guidelines
For Type I
Q/P = 0.26
.•.Q = (0.26) (5.72) = 1.48 cfs
For Type I I
Q/P = 0.26
:•Q = 0.26) (6.92) = 1.80 cfs
Concl us i on
Maximum required grate capacity is 0.3 cfs per drainage report. Therefore,
grates pravided will be adequate to dispose of maximum expected flows.
