Hogg’s Hollow Road and Stormwater Management Improvements
The City is currently reconstructing local streets throughout the Hogg’s Hollow neighbourhood. Phase 4 of a multi-phase project began in March 2015. Phase 4 work included reconstruction of streets, installation of storm sewers, curb and gutter and the replacement of the public portion of any substandard water services.
Revision to Project – 2018
In 2011, the City started construction of the recommended solutions in the Brookfield Road, Plymbridge Crescent, Donino Avenue and Plymbridge Road area. During the detailed design of a new 825 mm storm sewer on Donino Avenue (as proposed in the 2005 EA), a conflict was identified with an existing sanitary sewer on Donino Avenue, which made it not feasible to construct the proposed 825 mm storm sewer on that street. This necessitated a design change from the 2005 EA.
Based on an investigation of routing options, the City is recommending that the proposed 825 mm storm sewer be tunnelled from Brookfield Road through Brookfield Parkette and then along the western edge of 34 Plymbridge Crescent to connect to an existing manhole on Plymbridge Crescent. The storm flows would then be conveyed via a 900 mm storm sewer pipe on Plymbridge Crescent to an existing storm sewer on Plymbridge Road and discharge to an existing storm outfall at the Don River West Branch near the bridge on Plymbridge Road.
2018 Hoggs Hollow EA Project File Revision Notice provides details of the revised conceptual design of the storm sewer project in this area.
The study area is bound by Yonge Street in the west, York Mills Road to the north, Doncliffe Drive in the south and Highland Crescent/Bayview Ridge and the Rosedale Golf Club in the east. The black line delineates the study boundary.

The City studied various options for addressing problems related to stormwater management and road improvements in the Hogg’s Hollow nieghbourhood. The study was completed in 2005, and recommended the following:
- implementation of a series of source control measures on private property through a public education campaign
- implementation of a long-term road and storm water drainage improvement program, which involves reconstruction of the road network in the area, in conjunction with the installation of a storm sewer system capable of conveying stormwater up to a 100-year storm event, and a storm infiltration system for water quality purposes
- enhancing the municipal operations and maintenance program for the area

What is a Class Environmental Assessment?
Ontario’s Environmental Assessment (EA) program promotes good environmental planning by determining and managing the potential effects of a project prior to implementation.
The EA program ensures that public concerns are heard. EA balances economic, social, cultural and natural environmental needs so that projects benefit Ontario.
This study is being carried out according to the Municipal Class Environmental Assessment process. This is an approved approach to satisfying requirements of the Environmental Assessment Act specifically tailored to municipal infrastructure. The process includes identifying the problem or opportunity to be addressed, developing and evaluating a range of alternative solutions, providing opportunities for public input and identifying a preferred solution.
