# of Features: 21794
Status: ACTIVE
Layer Source: GIS_DATA.STM_PIPE
Layer Quality: Good
Feature Accuracy: +/- 1m
Type: POLYLINE
Description: Inventory of underground pipes draining surface water including culverts and bridge culverts. A storm pipe transports excess rain water, snowmelt water, or subsurface ground water from one location to another using the force of gravity (downhill fluid flow). A storm sewermain is physically comprised of many individual sections of physical pipe, however, for the purposes of representation and asset management, a single segment of sewer main is considered to be the assembly of pipe sections between physical access points, commonly referred to as manholes. A secondary type of storm sewermain that connects surface water intake structures known as catchbasins and inlets to the main storm sewer network is known as a storm lead. For the purposes of the system, storm leads are considered part of the inlet structure, and are not considered storm sewermains.

Data Fields & Domain Information

Storm_Pipes

Column Name Alias Data Type Comments Domain Name Default value Domain Values
OBJECTID OBJECTID NUMBER ESRI system maintained integer field used to uniquely identify rows in tables in a geodatabase. Note that OBJECTIID values change upon export or import of the data and should not be used as a primary field for searching or identifying records.
STMPIPEID Stmpipe ID NUMBER Database maintained field that permanently assigns a unique value for each record. This ID value should be the one referred to when identifying a record.
PARENTID Parent ID: ID of pipe that was replaces (if applicable) NUMBER GIS maintained field. Used when an an existing storm water pipe is split for any number of reasons. The existing record is split into 2 or more individual records. The longest single existing record retains its STMPIPEID value and no value is entered into PARENTID, however for each of the remaining shorter existing split records the original STMPIPEID value is copied into the PARENTID field, their STMPIPEID values are deleted and the database generates new STMPIPEIDs for the 1 or more new split shorter records. This is done so that information, such as work orders, could be linked back to the records that have new STMPIPEID values.
