Securing the Cities Improvement Act

Amends how the STC program (the program in Section 1928 of the Homeland Security Act of 2002) identifies, selects, and manages participating jurisdictions by focusing on jurisdictions with the right capability, capacity, and relative threat for terrorist or other high‑consequence radiological events. The change requires the program to adopt performance metrics, monitor how funds are spent, adjust selection criteria, and produce a report to Congress on participation and program performance within two years.

The amendment increases oversight and accountability: DHS must track outcomes and expenditures for jurisdictions in the program and tell Congress how the program is performing and who is participating. It does not itself appropriate new money or change tax law; it changes program design, selection standards, monitoring, and reporting.
