The City of Tacoma is working to improve elk habitats by controlling noxious weeds in the Green River Watershed. This effort is part of the Water Storage Project Mitigation and ensures compliance with state regulations.

To make tracking herbicide applications easier and more accurate, we’ve set up an automated GIS workflow that cuts down on manual data entry while keeping records accurate. Using ArcGIS Pro and Field Maps, data is collected and analyzed through web tools and dashboards, then automatically converted into PDF reports with Map Series functionality. Also, as data is collected, configured Attribute Rules enforce data integrity and create less data entry. This process ensures that documentation is both efficient and compliant.

By utilizing an automated process in GIS, these records not only help with compliance but also improve habitat management. In addition, real-time GIS data helps to make better decisions to control invasive species while reducing environmental impact.
