Using GIS to achieve ADA Title II Self Evaluation & Transition Plan Compliance

Interwest provides GIS services to public agencies to assist with the Americans with Disabilities Act’s (ADA) Title II Self Evaluation and Transition Plan requirements for agencies with 50 or more employees. The goal of this project was to perform a self evaluation of the City of Ceres’ programs, services, and public right-of-way and develop a transition plan for the City to ensure compliance with the ADA.  

ROLE OF GIS

GIS created a tool to assist the City of Ceres in automating the collection and monitoring of facilities and curb ramps.

DATA CREATION

The GIS Team acquired data from Stanislaus County, used existing City data and digitized new data needed to develop basemaps and for running the ranking analysis on the ramps. Our team created a data model to capture physical attributes and images of the ramps, published the data to the City’s ArcGIS Online account, and created web maps to be used for curb ramp collection in Collector for ArcGIS. 

Interwest GIS worked with the City to develop ranking criteria based on location and physical properties identified during collection to assist in mapping the curb ramps by priority. 

FIELD ASSESSMENT

Interwest provided a team of two field personnel who collected images and attributes in Collector on iPad minis. The assessment was completed in three weeks. 

After the field inspection phase was complete, the GIS team worked with engineers implement the ranking criteria. For example, ramps in high traffic locations with excessive slopes or concrete displacement would receive a high priority rank.

MONITORING AND PLANNING 

After all the rankings were determined, Interwest GIS created an overall city map displaying the curb ramps ranking and published it to the City’s ArcGIS Online account for viewing by City staff. 

City staff can use the data and map to monitor, plan, and track improvement of the curb ramps withing the City.
