The City of Greater Sudbury aims to protect surface water quality through management of development on shorelines of lakes, rivers and streams. Being the interface of land and water, shorelines are particularly important to water quality and fish and wildlife habitat.
New requirements related to shoreline development came into effect on February 1, 2022.
For current requirements, please see link to the Zoning By-law below.
Shoreline Buffer Areas
A Shoreline Buffer Area is an area of open land, abutting a shoreline, maintained in a naturally vegetated self-sustaining state including natural rock formations and for purposes of clarity does not include an area which is maintained as a lawn.
- A shoreline buffer of 20.0 metres will be required for development adjacent to a lake or river.
- A shoreline buffer of 12.0 metres will be required for development adjacent to a permanently flowing stream.
Why Maintain a Shoreline Buffer?
A shoreline buffer can help filter sediment and other pollutants (such as fertilizers and pesticides) from runoff that flows from the land into waterways, thus protecting the waters from nearby land uses. The shoreline zone also provides critical habitat for aquatic insects, microorganisms, fish, and other animals, thereby helping to maintain a balance in sensitive aquatic ecosystems.
A Portion Can be Cleared
On a residential lot, a maximum of 25% of the required shoreline buffer area can be cleared of natural vegetation, to a maximum of 276 m2.
The maximum length of the cleared area measured at the high water mark is 25% of the length of the shoreline, but in no case can the length exceed 23 metres. On a commercial lot, 33% of the required shoreline buffer area can be cleared of natural vegetation.
Structures Permitted within the Buffer
Accessory structures that are directly related to shoreline use are permitted within the shoreline buffer area. Gazebos, boathouses, docks, decks, stairs, water pumps and saunas are permitted within the shoreline buffer area.
Development on a Waterfront Lot Outside the Shoreline Buffer Area
Development Setback for Non-Shoreline Structures
Structures that are not directly related to shoreline use (camps/dwelling units, garages, sheds) are required to be located a minimum of 30.0 metres from the high water mark.
- Residential buildings and accessory structures are required to be set back 30.0 metres from the high water mark of a lake or river.
- Residential buildings and accessory structures are required to be set back 12.0 metres from the high water mark of a permanently flowing stream.
Setback for Septic Systems (Leaching Bed)
The septic system, including the leaching bed (essentially the pipes in the ground) associated with a septic systems must be setback 30.0 metres from the high water mark of a lake, river or permanently flowing stream.
