+55.7% KSI rate post-COVID — Pleasant Hill's severity crisis requires urgent intervention
Pleasant Hill’s KSI rate shifted from 7.69% (2015–19) to 11.97% (2021–25) — a +55.7% increase. Volume fell but each crash is significantly more likely to kill or severely injure — a severity crisis, not a volume crisis. 48 post-COVID KSI across 36 HIN corridors demand immediate targeted investment.
CCTSAP 2024 countywide action plan — Pleasant Hill-specific appendix available for adoption
CCTA adopted the Countywide Comprehensive Transportation Safety Action Plan (CCTSAP 2024) — a USDOT-eligible action plan covering all Contra Costa cities including Pleasant Hill. The CCTSAP includes a city-specific appendix for Pleasant Hill. Upon local adoption resolution and completion of the USDOT Self-Certification Worksheet, Pleasant Hill can apply for a FY2026 SS4A Implementation Grant targeting $5–12M federal.

⚡ Two-step path: Adopt CCTSAP appendix + complete Self-Certification Worksheet
Step 1: City Council adopts Pleasant Hill-specific CCTSAP appendix (available from CCTA). Step 2: Complete USDOT Self-Certification Worksheet confirming CCTSAP satisfies all required action plan components. If confirmed → submit FY2026 Implementation Grant by May 26, 2026. Contact CCTA for the Pleasant Hill appendix and eligibility guidance. Recommend pre-application USDOT review (due April 24, 2026).

What we bring to this application
2 prior HSIP projects prove Pleasant Hill delivery. H12-04-101 (BCR, $1.1M), H12-04-102 (SA-Ped, $350K). Each provides a direct template for C13 scale-up. Returning applicants with completion history are scored higher.
+55.7% KSI rate change — powerful post-COVID safety narrative. Pleasant Hill's severity shift (7.69%→11.97%) demonstrates the precise safety deterioration HSIP C13 prioritizes. SWITRS 2021–2025 data is fully analyzed: 248 dark (33 KSI), 221 speed (18 KSI), 85 ped (13 KSI), 98 bike (15 KSI).
Post-COVID (2021–2025) crash pools pre-validated for BCR calculation. All HSIP project recommendations based on 5-year post-COVID data only. Crash pools are quantified by countermeasure category — each application has a pre-validated data foundation for BCR submission.
SA-Ped and SA-Bike set-asides are low-risk, high-return. Both SA-Ped and SA-Bike have 80%+ win rates in C12. 73 SA-Ped and 30 SA-Bike projects funded C12 statewide. Submit 2 applications per category on different corridors (CONTRA COSTA BL + GREGORY LN).
C13 portfolio extends every prior HSIP investment in Pleasant Hill. Signal/LPI from H12-04-101 scales to citywide LPI+APS at 22 HIN intersections. Ped crossings from H12-04-102 replicates on CONTRA COSTA BL and GREGORY LN. Each C13 application directly extends proven C12 work.
