Integrating GIS into Dry Weather Screening Data Collection and Management
The City of Fairfax recently incorporated ArcGIS into its Dry-Weather Screening program, streamlining data collection and management. Field staff now have a map of available outfalls that have already been location verified and condition assessed, taking the guesswork out of planning for annual dry-weather screening. Previously, data was collected by consultants and delivered to the City as PDF reports. Aside from annual reporting, dry-weather screening data was underutilized. Starting in 2024, the City worked with consultant partners to migrate the collection and storage of data into the City’s ArcGIS organization. Contracted staff use an integration of ArcGIS Field Maps and Survey123 to conduct surveys and compile the data for review. This change allows City staff to leverage powerful ArcGIS solutions to analyze data and monitor trends from current and past inspections. As the City completes the second round of GIS-based dry-weather screening, we will take some time to examine the initial development and data collection, challenges encountered, and how this updated methodology provides additional insights for long-term stormwater management concerning illicit discharge.
