It's been 10 years since the original Subwatershed 19 was complete and Credit Valley Conservation has started work on an update to indicate what effect all the development in Orangeville over the years has had on the creeks and tributaries.

This update will have the information collected during the original study and a detailed impact assessment to determine the potential effect of future development as well. The purpose of the study is to provide guidance to the Town, developers and regional and provincial governments on land use decisions, while striking a balance with the needs of the environment. It will also give guidance on how to prepare development proposals for non-government organizations and private land owners.

It will recommend how water resources and related subwatershed feature and ecological functions should be protected and enhanced to sync with existing and future land use changes.

The study will identify constraints, opportunities and approaches for input into land use planning decisions and provide information for municipal planning decisions and outline requirements for development proposals.

The subwatershed plan includes specific subwatershed targets, goals and objectives to establish, delineation using field data, surface and groundwater modelling, update information, directives for future studies, an implementation plan, a monitoring plan, recommendations for improved agricultural practices, recommendations for stewardship of sensitive areas and

recommended plans on planning and policy, education and stewardship, rehabilitation, retrofit and monitoring.

It identifies sources of contamination, key issues, goals, preliminary mitigative measures, water resource targets and resource constraints.

There are four phases in the plan that will aim to answer a number of specific questions in each stage. Phase 1 is subwatershed

characterization; phase 2 for prediction and impact analysis; phase 3 for implementation and identifying alternative solutions and phase 4 is for long-term monitoring.

The study will benefit Orangeville, Mono, Caledon, Amaranth and East Garafraxa.

If Orangeville council were to accept the study recommendations, they will be incorporated into the town's Official Plan.
