Outline

Non-Motorized Trans. Comm.

Committee was originally concerned solely with trails. Over time the focus has extended to include pedestrian safety, on-road bike lanes. The Trail Plan was updated in 2002. The committee proposed changes to the plan. Public hearings were held before the Planning Commission and Board of Supervisors.

Major Activities

Pedestrian and Bicycle Safety

Conclusions

Eminent domain is a tool used for ensuring that our roads connect. It has not been used in the past to connect trails, which is one reason for the gaps. A reluctant homeowner can stop any project.
