Planning Services

Central Lake Ontario Conservation (CLOCA) is part of the land use planning system in partnership with local municipalities and the Region of Durham


We review land use plans, applications under the Planning Act and supporting technical reports and drawings to provide formal comments that address environmental and public safety considerations.  Specifically, we review: 

  • Official Plans and Zoning By-laws and Amendments

  • Secondary Plans, Subwatershed Plans and Servicing Plans

  • Consents / Land Division

  • Minor variances

  • Site plans


We seek to ensure that development issues are addressed through comprehensive and integrated land use planning prior to proposals reaching the development permit stage.  We do this, in part, by providing early and comprehensive input into the municipal planning process and through assisting in the implementation of provincial, regional and local land use plans. 


CLOCA offers information and analysis on natural hazards and natural heritage features and systems including:

  • Flood plain management

  • Erosion and slope stability

  • Wetlands

  • Shorelines of lakes, rivers, and streams

  • Ravines, valleys, and stream corridors

  • Natural Heritage Features and Systems

  • Groundwater, Source Water Protection, Hydrologic Features and Areas

  • Fish and fish habitat protection

  • Wildlife, movement and habitat protection
