Thompson Creek Flood Study Report - City of Peterborough

Thompson Creek Detailed Flood Reduction Study
City of Peterborough
1. Drawing SF-3 shows the estimated extent of flooding for the 40 mm and 60 mm
events for Scollard Drive. The 193 mm event produces lower flows and water
levels since it is distributed over 12 hours. As indicated, three lots are affected
on the west side of the bend in Scollard Drive. The reasons for flooding are as
previously discussed in Section 4.6.2.2. As noted earlier, potential solutions to
this problem are discussed in Section 5.1.
2. Drawing SF-3 shows the extent of potential ponding at the corner of Eldon
Court and Francis Stewart Road for the 40 mm and 60 mm storms. As
previously discussed, for infrequent events the ponded flow would overtop the
curb and flow west from the affected location and spill onto the adjacent private
property. Although no direct flood damages would be caused, potential means
of alleviating this “nuisance” flooding are discussed in Section 5.2.
