Generic Regulations
The Crowe Valley Conservation Authority (CVCA) has a regulation called Ontario Regulations 159/06 Development, Interference with Wetlands and Alterations to Shorelines and Watercourses.
Its purpose is to protect public safety , property and the environment. This is accomplished by requiring approval through permits for work that could impact by what are referred to as natural hazards.
Natural hazards are processes such as flooding and erosion that could be worsened if development ( buildings and structures) and site alterations (i.e. filling, excavating and grading) are not conducted in a manner that accounts for potential impacts.
The CVCA's review process under the regulation ensures that no negative impacts relate to natural hazards will result from work.
