A polygon feature class showing SPU watersheds. It also provides information on its shed and type. 

Underdrain piping systems are provided to prevent prolonged ponding of stormwater or to collect and convey water to another facility. Rain gardens are less engineered systems...

A polygon feature class showing DWW Swales. It also provides information about its exact location, owner, and role. Swales (biofiltration, bioretention,...

A presentation feature class displaying large structures that define the end of a mainline such as maintenance holes, vaults, plugs, or other designated features.

Footprint of various structures associated with mainlines.

Each polygon has an associated drain line feature that is used to show the basic direction that drainage flow may be travelling during a storm event.

In the polygon data, Facility Footprints details the footprint of the swale, permeable pavement, and rain garden features.

Active smaller structures that provide piped access such as wyes, clean outs or stand pipes. Other feature types such as bends are also included.

Permeable pavement is a paving system which allows rainfall to percolate into an underlying soil or aggregate storage reservoir.

An outfall is where drainage water leaves a pipe and drains out of the formal sewer and drainage system into a stream, body of water, ditch, etc.

Designed large structures that will define the end of a mainline such as maintenance holes, vaults, plugs, or other designated features.
