The mapping tool can be used to gain an understanding of a property and to identify potential natural hazards or regulated areas. If your property is within a regulated area, you will require a permit from LRCA for any proposed development. This is in addition to a building permit or other approvals from your municipality and other agencies. Not all regulated areas have been identified in this mapping application and it is important to know that the Regulation still applies under these circumstances. The screening limit data is conceptual in nature.
