Notice of Study Commencement

Two-Zone Floodplain Mapping and Flood Mitigation Update Study Oshawa and Goodman Creeks

Central Lake Ontario Conservation (CLOCA) through a Watershed Flood-Risk Assessment (2017) has identified an at-risk area upstream of the Canadian Pacific Railway subject to flooding within the City of Oshawa as shown in the figure. This flood hazard area has historically been managed using the two-zone concept. A specific policy has been in use for this two-zone concept area that provides direction on the type and form of development that may be permitted within such an area due to flooding constraints.

CLOCA, in association with the City of Oshawa, wishes to update their Two-Zone Flood Policy and the associated mapping for the study area based on the update of the Floodplain Mapping completed by CLOCA in 2014.  
 

This notice is provided to indicate the commencement of the two-zone floodplain mapping update study. 
 

In general, this study will re-define the floodway and the flood fringe areas based on the most up-to-date floodplain information, re-examine possible mitigation options to alleviate flooding in the area and undertake an impact assessment on future developments in the White Belt areas.
 

The study is to follow the spirit of the Municipal Class Environmental Assessment process and therefore will include opportunities for public review and input. Notice of a Public Information Centre (PIC) will be provided at a later date.
 

Public input and comments are invited for incorporation into the updating of the two-zone floodplain mapping. Interested parties desiring further information or wishing to provide input or comments are invited to contact the following:
