Thompson Creek Flood Study Report - City of Peterborough

Thompson Creek Detailed Flood Reduction Study

without a detailed review of the drainage on the private property but if feasible might be
of the order of $10,000 per property.
5.5 FLOOD PROTECTION RECOMMENDATIONS
Based upon the evaluation of flood vulnerability and evaluation of flood protection
options, the following actions are recommended:
1. The City should consider implementing the preferred alternative (Option No. 1:
increased inlet capacity and parallel sewer to capture 1 in 100 year storm flow) to
reduce the frequency of flooding at the corner of Scollard Drive near the intersection
with Francis Stewart Road. This is the highest priority flood vulnerable area in the
Thompson Creek study area.
2. The City should review the potential flood remedial works discussed for the other three
flood vulnerable areas in the context of the overall City priorities and determine
whether implementing them is justified. These are all essentially cases of nuisance
flooding which could be reduced by implementing the measures discussed.
3. The City does not need to implement any remedial measures along the Thompson
Creek watercourse to address flood vulnerability from the range of storm events
considered in this study. However, the City should strongly encourage the Trent Severn
Waterway to undertake a study to define more accurately the flood risk related to
releases from the Thompson Creek Dam and to establish a policy on the maximum
permissible releases from that facility. The study should also include an assessment of
dam safety and the consequences of a failure of the structure.
4. Given the existence of this document as a Master Plan under the Municipal Class EA
(2000), the lack of environment impacts of any of the suggested projects and their
limited scale/scope, it should be feasible to implement them without further EA
process.
