B-Seam Dewatering System
25yr - 24hr event
Primary spillway on Last Chance Pond is user defined base off
of manufacturer data for 1.0'H Flume (Tracom),
Note: Structure #1 (Dewatering Pond #3), SWS#4 was
added to simulate the volume of 100 gpm (0.22 cfs) coming
from dewatering discharge during the peak storm event,
Acreage of this 5W5 was adjusted to match the increase in
flow.
Dewatering Ponds #1 and #2 were not modeled to allow for a
conservative approach and operational flexibility to divert
flow around these ponds for maintenance.
