Name: Surface Water Supply Protection Areas (MassGIS)

Display Field: SITE_NAME

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: These Surface Water Supply Protection Areas delineate those areas included in 310 CMR 22.00, the Massachusetts Drinking Water Regulations, as Surface Water Supply Protection Zones: ZONEA: represents a) the land area between the surface water source and the upper boundary of the bank; b) the land area within a 400 foot lateral distance from the upper boundary of the bank of a Class A surface water source, as defined in 314 CMR 4.05(3)(a); and c) the land area within a 200 foot lateral distance from the upper boundary of the bank of a tributary or associated surface water body. ZONEB: represents the land area within one-half mile of the upper boundary of the bank of a Class A surface water source, as defined in 314 CMR 4.05(3)(a), or edge of watershed, whichever is less. Zone B always includes the land area within a 400 ft lateral distance from the upper boundary of the bank of a Class A surface water source. ZONEC: represents the land area not designated as Zone A or B within the watershed of a Class A surface water source, as defined in 314 CMR 4.05(3)(a). All active and inactive surface water supplies have zones delineated, but some may be covered by other legislation. Watershed extents for all surface water supplies including active, inactive, emergency, sources outside of Massachusetts, watersheds that extend into other states and watersheds of sources from other states that extend into Massachusetts are included in the datalayer SWP_Watersheds. Surface water intakes on Class B Rivers are not included in either datalayer. The reservoir features were taken from the DEP Wetlands 1:12000 datalayer and removed from the Zone A and B features and added as a separate feature.
