The Storm Detention Site polygon feature class represents the location and attributes of storm detention sites within the City of Auburn. These sites provide temporary storage of stormwater runoff from the City’s underground stormwater infrastructure.
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.

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.

QA/QC
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.

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 Detention Sites 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.
