<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>The Storm Outfalls feature class is a spatial dataset that represents the location and key attributes of storm outfalls within the City of Auburn's stormwater drainage system. These outfalls are the exits of culverts, pipes, and channels which facilitate the controlled movement of surface runoff and helping to reduce flooding, erosion, and sediment transport. While outfalls nodes are assigned to all stormwater conveyance line geometry to signify the exit of a structure which does not have a dedicated storm structure at the end of the segment, the 'outfall' can also be a physical device controlling the flow of stormwater into natural waterways where applicable. This feature class provides essential information for asset management, system modeling, and infrastructure planning, supporting effective operation, regulatory compliance, and the long-term sustainability of the city’s stormwater management network.</SPAN></P></DIV></DIV></DIV>

The Storm Outfalls point feature class captures the geometry and attributes of storm outfalls within the City of Auburn. Storm outfall is the technical term for the open downstream exit of culverts, pipes, and channels when a physical storm water control structure does not exist. Occasionally, outfalls can also be physical devices controlling the flow of storm water into natural waterways.
City of Auburn Public Works Department: Responsible for data collection, maintenance, and updates of the storm network.
City of Auburn GIS Team: Ensures the spatial accuracy, integration, and management of storm datasets within the GIS system.

Though the City of Auburn's GIS storm inventory efforts had concluded in 2023, storm assets are continually installed, retired, and repaired. These ongoing changes are tracked in GIS via the intake process of as built documents pertaining to COA and private projects throughout the city.

The Storm Outfall feature class was initially imported into GIS using existing CAD drawings circa 2004. From that time to the present day, assets have been added through an as-built intake process along with other storm infrastructure as well as during a comprehensive storm inventory effort ending in 2023. Storm outfalls are maintained by the City of Auburn’s Maintenance and Operations crew and are periodically retired or replaced via improvement projects or new development construction. The dataset is maintained in a Enterprise Geodatabase and is regularly updated to reflect storm system expansions, rehabilitations, and retirements.
As projects continue throughout the City of Auburn, assets are updated and retired from the storm infrastructure system. As-built construction plans record the installation/retirement of storm infrastructure and are processed by GIS staff at a delay of approximately one to two years from in-field action. All edits to the feature class honor QC standards created during the storm inventory effort to best align with sound data practices. This process will be on going for the life time of this feature class.

As built intake process.
As-built drawings and related engineering documents were reviewed to verify and update the spatial location and attribute information of storm manholes along with GPS data for spatial location and elevation. Discrepancies existing in GIS data were identified and corrected using as-built information as well as field verification. Updates included adjusting feature geometry for accuracy and revising attributes such as installation date, ownership, depth, flow direction, and status. All updates were performed in ArcGIS Pro and ArcMap, with attribute domains enforced to maintain data integrity. Quality control checks, including topology validation and domain compliance, were conducted following updates to ensure consistency and accuracy of the dataset.

OMS integration refinement.
All dataset features conform to established data quality criteria and have been validated through a comprehensive storm inventory process ending in 2023. Any inconsistencies in attributes, coded domains, or relational structures were addressed during the review.
QA/QC
The Storm Outfalls feature class, while thoroughly inventoried, is under active development as new storm projects are created and older infrastructure is retired. Updates occur regularly to improve completeness and accuracy of this dataset.
