Costs and Funding

 About $100 million is needed to improve all existing non-compliant assets in the 2018 inventory.

Cost model
Our cost model assigns estimated unit costs to each non-compliant asset, which were used to calculate the total $100 million cost.

First, we set unit costs based on each impact level. Impact levels are determined by factors such as current conditions, right-of-way acquisition or connection to nearby assets.

Then we identified the total cost by asset type and impact level:

Pedestrian push button

Level of Impact Low High Total
Cost per push button $1,250 $6,000  
Non-Compliant (each) 188 393 581

Funding sources

The ADA Improvement Program will use several funding sources to make the entire county accessible. ADA improvements will be funded either as stand-alone projects or as a part of another road improvement project.

Potential funding sources include:

Local funding programs
County Road Fund: This is the primary source for funding to plan, improve, maintain, and operate the county road system. It comes from the road levy portion of the property tax and a portion of the State Motor Vehicle Fuel Tax. This funding will be used for the ADA Improvement Program’s annual work.

Traffic Impact Fees: These fees are charges on new development. They pay for improvements to the transportation system needed for the new development. These fees will only be used on capital improvements, which may include existing pedestrian assets. They will not be used for stand-alone ADA projects.

Federal and State Funding Programs
We pursue grants offered by agencies such as:
  • Washington State Transportation Improvement Board
  • Washington State Department of Transportation
  • Federal Highway Administration
  • Puget Sound Regional Council
