Allocation of Capacity Units

A policy is in place for allocating capacity in Cowichan Bay sewer system, consistent with CVRD Electoral Area D – Cowichan Bay Official Community Plan.  A key goal of the OCP is to “Carefully Manage Growth” by directing development to areas within established Village and Rural Village Containment Boundaries and to areas which are identified as having existing or potential sewer service.  Another key goal of the OCP is to “Restore, Protect, and Enhance the Health of the Cowichan Estuary and Marine Foreshore”. Correspondingly, properties directly adjacent to the Cowichan Estuary and Marine Foreshore, which are outside of Village and Rural Village Containment boundaries, are identified as having potential for sewer service.  The Cowichan Bay Sewer Servicing Policy can be found here.
