The Sewer Main feature class represents the underground infrastructure of the City of Auburn’s sewer system, capturing the location and attributes of the main sewer lines that facilitate wastewater conveyance.
<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>The Sewer Main feature class is a geospatial dataset representing the city’s primary sanitary sewer pipes that convey wastewater from residential, commercial, and industrial areas within the City of Auburn’s sewer service area boundary. The dataset includes detailed information on the location, alignment, diameter, material type, associated assets, and age of each sewer main segment. The feature class is maintained as part of the city’s asset management system and is updated regularly to reflect changes such as new construction, repairs, or replacements. The data is used by the city’s Public Works Department, engineers, and GIS professionals for analysis, planning, and operational tasks, including monitoring system performance, identifying maintenance needs, and conducting capacity studies. Additionally, the Sewer Main feature class supports compliance with regulatory requirements related to wastewater management and facilitates the development of infrastructure improvement plans.</SPAN></P></DIV></DIV></DIV>
City of Auburn Public Works Department: Responsible for data collection, maintenance, and updates of the sewer network.
City of Auburn GIS Team: Ensures the spatial accuracy, integration, and management of sewer datasets within the GIS system.
Maintenance of this layer is on going according to the GIS sewer inventory effort and will be updated continually as assets are repaired, retired, or installed.

Esri
This field represents the geometric length of the sewer pipe feature, calculated automatically by the GIS system based on the shape geometry. Because this value is derived directly from spatial data and is continuously calculated, it does not have a fixed set of allowable values or ranges that can be explicitly enumerated. Therefore, the domain for this field is unrepresentable.

Metadata is subject to change as the City of Auburn continues to refine our GIS datasets. Additionally, periodic reviews of metadata will occur to ensure accuracy of data contacts, attribute definitions, and domain structures.
The Sewer Mains feature class was developed using a combination of original as-built drawings, field survey data collected by City of Auburn staff, and existing GIS data layers. Initial spatial data were digitized from imported CAD drawings in 2004. Attribute information was compiled and cross-checked from maintenance and operations records, asset management databases, and recent system inspections. Data integration and quality control processes were employed to ensure accuracy and consistency. The dataset is maintained in a Enterprise Geodatabase and is regularly updated to reflect sewer system expansions, rehabilitations, and retirements and is undergoing a current sewer inventory effort as of 2026.
As-built drawings and related engineering documents were reviewed to verify and update the spatial location and attribute information of sewer mains. Discrepancies between existing GIS data and as-built records were identified and corrected using field verification and DTM data. Updates included adjusting feature geometry for accuracy and revising attributes such as pipe material, diameter, installation date, and status. All updates were performed in ArcGIS Pro, with attribute domains and subtypes enforced to maintain data integrity. Quality control checks were conducted following updates to ensure consistency and accuracy of the dataset.

All features in the dataset meet established completeness criteria once reviewed. No discrepancies were found in geometry types, coded value domains, or expected feature relationships during the inventory process. Attribute rules were used as QA measures where applicable.
The sewer mains dataset is under active development and inventory. While significant portions of the service area have been surveyed and digitized, some sections remain incomplete or unverified. New features are continuously added as field inspections and data collection progress. Updates occur regularly to improve completeness and accuracy.
