Project prioritization

Project prioritization

The ADA Transition Plan outlines how we will prioritize ADA improvement projects to serve the most people using available resources.

We have developed a scoring system for each type of facility based on:

This score measures how difficult it is for a person with disabilities to use a facility. Each facility type is measured on its designed features. For example, measurements for a sidewalk include width, slope, and cross slope (slope that is perpendicular to the direction of travel), whereas measurements for an accessible pedestrian signal include button height and spacing. A sidewalk that is too narrow and too steep will receive a higher condition score when compared to a sidewalk of standard width that is slightly over the standard for cross slope. The more out of compliance a facility is, the higher the score will be.

This score is based on the types of services nearby and the expected amount of use. Facilities that serve an area with a high concentration of services, transportation, and employment receive higher scores than those in low-density residential areas.

Facilities will receive higher location scores if they are near services such as:
illustration of a high-density residential area
High-density residential zones
illustration of a transit center with an person using a wheelchair boarding a bus
Transit centers and bus stops
illustration of a school and a hospital
Government offices, schools and hospitals

This score is calculated by adding the condition and location scores together. Priority scores are used to determine patterns and target project candidates.

How many facilities are out of compliance?

The number of facilities that are out of compliance changes as new facilities are built or improved.
