The City of Ottawa has initiated a Stormwater Management (SWM) Criteria Study for the Feedmill Creek Subwatershed. The need for the project was identified in March 2015 based on the review of the Carp River hydraulic model. The study area is shown below:
According to the City's Official Plan, future development will significantly increase the imperviousness of the subwatershed. The additional runoff volume generated by the increased imperviousness can result in potential impacts on the creek, including flooding, erosion and degraded water quality. In order to ensure that impacts on the creek are mitigated, the existing SWM criteria for Feedmill Creek need to be revisited. Where SWM alone may be insufficient, recommended stream rehabilitation works are to be identified.
This study will confirm stormwater management requirements for the remaining development within the subwatershed and identify retrofit opportunities for existing development. The study's objective is to ensure the impacts of new development on Feedmill Creek are mitigated.
The Study schedule is a follows:
- November 2016 - Draft SWM criteria
- November 2016 - Draft results posting on ottawa.ca
- January 2017 - Presentation of final report/recommendations at Planning Committee
- January 2017 - Final Report presented to City Council
