As part of this process, STA staff and consultants confirmed or reestablished local Community Task Forces, identified priority projects, and conducted walk audits in each district. The updated plan outlines the program’s five-year vision, incorporates community input, and highlights priority projects for each school district.

Community members, school staff, and other stakeholders are encouraged to review the draft plan and submit comments. The deadline for public comments is October 15, 2025.
