Evari audited curb ramps in Oregon’s Clackamas, Multnomah, Hood River, and Washington Counties for ADA compliance, utilizing a specially designed database populated with existing ODOT ramp data. Their ArcGIS Enterprise solution enabled field data and photo collection through Evari’s Audit App, real-time project tracking via a custom web application, and post-collection edits to ramp data.

Evari enhanced audit efficiency by pre-populating ramp attributes using spatial analysis and collected additional back-of-walk (BOW) geometry data. Challenges with GPS signal obstruction were overcome by using GNSS for greater spatial accuracy. This comprehensive ADA Curb Ramp Asset Inventory Database Development and Support project aided ODOT in pinpointing ramps needing reconstruction for ADA compliance.
