Metadata Summary

Originator	Metropolitan Council
Abstract	This layer contains the rough boundaries of the sewersheds for the Twin Cities metropolitan area. A sewershed is a defined area that is tributary to a single point along an MCES interceptor pipe (a community connection to an interceptor) or is tributary to a single lift station. Community boundaries are also used to define sewer-shed boundaries. The data are derived from community comprehensive sewer plans. Notes: - The sewersheds are estimated. The actual sewersheds may be different. - Not all records contain county or MCD information.

Title	Sewersheds
Abstract	This layer contains the rough boundaries of the sewersheds for the Twin Cities metropolitan area. A sewershed is a defined area that is tributary to a single point along an MCES interceptor pipe (a community connection to an interceptor) or is tributary to a single lift station. Community boundaries are also used to define sewer-shed boundaries. The data are derived from community comprehensive sewer plans. Notes: - The sewersheds are estimated. The actual sewersheds may be different. - Not all records contain county or MCD information.
Purpose	To provide more manageable areas for flow analysis and planning and to distinguish between the sewered and unsewered areas within the Metropolitan Urban Service Area (MUSA).

Logical Consistency	The dataset is topologically 'clean'.
Completeness	Entire seven county geographic area is covered.
Horizontal Positional Accuracy	The positional accuracy of the dataset has not been tested under the National Standards for Spatial Data Accuracy. The positional accuracy of the dataset is UNKNOWN.
Lineage	The dataset includes information from comprehensive plans submitted as of March 18th, 1997. The dataset is derived from community comprehensive sewer plans and is referenced to the MnDOT (1992) street base. The dataset is updated as new comprehensive plans are submitted to the Council. The sewersheds are estimated. The actual sewersheds may be different.
