Additionally, periodic reviews of metadata will occur to ensure accuracy of data contacts, attribute definitions, and domain structures. The Sewer Manholes 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, including DTM-derived elevations for rim heights. 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 manholes. Discrepancies between existing GIS data and as-built records were identified and corrected using as-built information as well as DTM elevations. 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, with attribute domains and subtypes 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. QA 2025-10-15T00:00:00 The sewer cleanout 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. All features in the dataset meet established completeness criteria when 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.
