A Tale of Two Experience Builders: Migrating Tacoma's Map Applications

Thursday May 21, 2026 8:30am - 9:00am PDT

Two of the City of Tacoma's most foundational and complex web map applications are the Equity Index and Staff DART (an internal, "kitchen-sink" application). Over the course of 2025, we migrated both of these highly customized applications to Esri's Experience Builder. We’ll share how we preserved core functionalities, enhanced design and usability, and improved performance. Along the way, we will also highlight key lessons learned, technical challenges, and practical insights to support others considering migrating similar complex application solutions.

Using Native SQL Geometry for Cloud-Ready, Lightning-Fast Overlays

Thursday May 21, 2026 9:00am - 9:30am PDT

407-408

Serving high volume, complex reports that require querying dozens of GIS layers for a single parcel is a major performance hurdle. Our Districts and Development Conditions Report simultaneously queries nearly 60 layers, which has the potential to severely impact application performance. This session details the architectural overhaul we implemented to overcome this challenge without changing the core query structure. Our key improvements were optimizing the underlying data storage by moving to the native SQL Server geometry type and using spatial SQL queries.

Chehalis River Basin Early Flood Warning System - A Decision Support Tool

Thursday May 21, 2026 9:30am - 10:00am PDT

401-402

This presentation will describe how GIS is used as a decision support tool providing critical and timely information to citizens and first responders in the flood-prone Chehalis River Basin as well as to communicate the value of continued investment in early flood warning to stakeholders. To highlight the Chehalis River Basin Flood Authority (CRBFA) team’s National Hydrologic Warning Council (NHWC) Operational Excellence Award-winning flood warning system, Ms. Harvey and her team, in coordination with Scott Boettcher of SBGH-Partners LLC, developed and actively maintains a Flood Warning System Gage Alert Program ArcGIS Data Dashboard and a Flood Warning Email Alerts Sign-up smart form with ArcGIS Survey123. Used as informational and interactive tools for the 175,000+ residents of the Chehalis River Basin, the Flood Warning System Dashboard has promoted accountability, showcased results, and monitored progress during the 2022–26 flood seasons. At the same time, the Survey123 Email Alert System Sign-up page has become the first line of defense by providing Chehalis River Basin residents with a practical smart form that allows users to easily select gage alerts of interest and sign up online. Additionally, the Dashboard allows users to connect to the Chehalis River Basin Flood Warning System website, which provides a variety of forecasting tools including flood inundation maps.

Covington Water District Chat Bot

Thursday May 21, 2026 9:30am - 10:00am PDT

407-408

This presentation describes an AI application developed for Covington Water District that combines conversational AI with GIS-based utility analysis. The application includes dedicated GIS routes for parcel water availability and meter lookup, allowing users to ask natural-language questions about whether water service is available to a property, whether nearby infrastructure exists, and what existing meter information is associated with a parcel or address. It can also combine GIS findings with district documents such as administrative code, standards, rate tables, and forms to provide a single, grounded answer. The talk focuses on the GIS side of the application: how location-based questions are routed into parcel and meter workflows, how spatial data is connected to policy and service requirements, and how conversational AI can improve access to GIS-driven utility information for local government and water district operations.

How to Build a Production App and ETL in One Week(ish)

Thursday May 21, 2026 10:30am - 11:30am PDT

401-402

“We need this application ASAP!” Have you received this type of request before for a complex application? In this session we will walk through how a Restaurant Safety Ratings Application was created — from raw SQL data to a polished public-facing web application — designed, built, and deployed in roughly one week using a combination of Experience Builder and AI-assisted development. The session will be broken into two main parts.

App Development in ArcGIS Experience Builder
Rather than rebuilding a custom web application from scratch, the new Restaurant Safety Ratings application was built entirely in ArcGIS Experience Builder. We will get into the weeds about how the application was configured, some clever use of Arcade, and tips and tricks for building scalable and accessible applications.

Data Pipeline Development with VS Code and AI Assistance
Data pipeline development was accelerated significantly using GitHub Copilot within VS Code. We'll explore how to develop GIS data pipelines with AI beyond 'vibe-coding' — and walk away with a better understanding of the implications of using AI to help with future GIS projects.

New ArcHydro tools to facilitate connecting data to hydrography through linear referencing

Thursday May 21, 2026 1:30pm - 2:00pm PDT

401-402

Linear referencing in hydrography is a way to locate information along rivers and streams using distance measured along the waterway, rather than using map coordinates. This makes it easier to link data—such as sampling points, monitoring stations, or stream segments—to their exact position on a stream network. These linked datasets are commonly referred to as “events” and support analysis of relationships among different hydrologic observations.
Linear referencing and dynamic segmentation are widely used in water resources to connect attribute data to specific parts of water features. This is critically important to make hydrography data useful for modelling, policy, conservation and a better understanding of our surface waters. Historically, this process has relied on the National Hydrography Dataset (NHD) and reach codes. However, a modernized approach is needed since reach codes are no longer maintained and are not part of the 3D Hydrography Program (3DHP).
Washington Department of Ecology has been working with Esri’s Arc Hydro team to develop simplified data models and tools that can be used with ArcGIS Pro, to provide a foundation for developing an updated linear referencing system. This presentation introduces new Arc Hydro tools and workflows for managing events, explains the development of a linear referencing system based on elevation derived hydrography (including 3DHP), outlines methods for transitioning existing events from NHD to 3DHP, and demonstrates techniques for analyzing and visualizing events using dynamic segmentation.

Powering the Future: Mapping Solar Potential Across WSDOT Rights‑of‑Way

Thursday May 21, 2026 2:00pm - 2:30pm PDT

401-402

Washington State Department of Transportation (WSDOT), in partnership with The Ray, conducted a statewide GIS-based suitability analysis to identify highway rights‑of‑way with high potential for solar energy development. Using spatial criteria, terrain analysis, and solar radiation modeling, the study identified over 3,000 acres of highly suitable land capable of supporting significant renewable energy generation. A pilot effort further evaluated opportunities to co-locate solar infrastructure near WSDOT communication sites by integrating proximity analysis, Utility Franchise Permit data, and statewide power plant locations. This work demonstrates how geospatial analytics can optimize state-owned transportation corridors for clean energy deployment while supporting Washington’s climate and infrastructure objectives.

Unlocking the Past to Empower the Future: Geo-Enabling WSDOT’s Statewide Real Estate Parcel Inventory

Thursday May 21, 2026 2:30pm - 3:00pm PDT

401-402

The Washington State Department of Transportation (WSDOT) Real Estate Services (RES) oversees an extensive archive of Real Estate Maps documenting parcels acquired to build and maintain the state’s transportation system. Many of these maps—especially those produced prior to 2010—exist solely as scanned images, limiting their usability in modern geospatial workflows and slowing access to crucial property information.
To bridge this gap, WSDOT RES has launched a statewide initiative to georeference historical Real Estate Maps, digitize parcel boundaries, and connect key acquisition records directly to spatial features. This effort is creating a unified, GIS-enabled Parcel Inventory that modernizes how real estate data is stored, accessed, and used to support planning and operational needs.
This presentation will walk through the end‑to‑end lifecycle of the Parcel Inventory Project—from archival research and data preparation to georeferencing, polygon creation, and enterprise database integration. The resulting geodatabase will become a mission‑critical asset, improving decision-making, streamlining RES workflows, and increasing transparency and accessibility of property records across Washington State.
