Link to this table

Design methodology
1-yr 24-hr Instantaneous volume 1-yr 24-hr routed (R124) 1/2 Pre-development 2-yr 24-hr peak Instantaneous volume 1/2 Pre-development 2-yr 24-hr peak routed (R224)
Weir length (ft) 0.8 3.7 0.8 4.8
Weir elevation (ft) 109.2 108.2 109.9 108.6
Surface area at weir elevation (ac) 0.9 0.9 0.9 0.9
Peak discharge per design event (cfs)1 36.7 36.0 36.7 36.4
Peak water elevation per design event (ft) 114.7 110.2 114.77 110.1

1Because the 10-year flow rate is designed to match the pre-development peak, the values in this row should be all less than or equal to 36.7 cfs.
