Geometry Type: esriGeometryPolygon

Description: In York Region, the WHPA-Q1 and WHPA-Q2 are identical in size and shape. These areas are used to identify locations of potential water quantity threats. There are two types of threats: those associated with water demand and those associated with reductions to groundwater recharge. The WHPA-Q1 delineates an area where there is potential for water demand threats (i.e. new wells). The WHPA-Q2 delineates an area where there is potential for threats from reductions in groundwater recharge (i.e. new development). The WHPA-Q1, WHPA-Q2 were delineated as part of the York Region Tier 3 water budget study that was completed for the Clean Water Act, 2006. A water budget is a quantitative measure of the hydrologic cycle components and an understanding of the processes and pathways in which water flows through watersheds. These two areas were delineated using the Tier 3 Water Budget numerical model. Please refer to the Clean Water Act approved symbology when using this data.
