Development Process Flowchart

Wellington County Official Plan

Site Plan Control is used by the Town of Erin to ensure that development is safe, functional, and compatible with surrounding neighbours and the overall community. This tool also allows for the Town to have specific quality and appearance standards that are reflected in each development project. The process and requirements of site plan control areas are outlined in Section 41 of the Ontario Planning Act.
The Site Plan Control process allows for the entire site to be considered by Town Departments. It takes into consideration items such as landscaping, pedestrian and vehicular access, infrastructure and municipal services, drainage, and can ensure a property is aesthetically pleasing. The entire Town of Erin is designated as a Site Plan Control Area by By-law #01-32 and a sample site plan agreement is included in By-law #16-38. Although all of the Town is within the Site Plan Control Area, some development is exempt from the process.

All inquiries should be directed to Town of Erin Office planning contacts:
