Safety case & program alignment
+0.9% KSI rate post-COVID — Oakley's severity crisis requires urgent intervention
Oakley’s KSI rate shifted from 12.25% (2015–19) to 12.36% (2021–25) — a +0.9% increase. Both volume and severity are rising — compounding the safety challenge. 32 post-COVID KSI across 23 HIN corridors demand immediate targeted investment.
CCTSAP 2024 countywide action plan — Oakley-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 Oakley. The CCTSAP includes a city-specific appendix for Oakley. Upon local adoption resolution and completion of the USDOT Self-Certification Worksheet, Oakley 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 Oakley-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 Oakley appendix and eligibility guidance. Recommend pre-application USDOT review (due April 24, 2026).

What we bring & recommended ask
-
CCTSAP 2024 provides the action plan foundation — Oakley-specific appendix available. CCTA's adopted countywide CCTSAP covers all CC cities. Oakley should adopt the city-specific appendix by Council resolution and complete the USDOT Self-Certification Worksheet to confirm implementation grant eligibility by May 26, 2026.
-
+0.9% KSI rate shift — compelling post-COVID safety narrative. Oakley’s severity shift (12.25%→12.36%) over equal 5-year windows demonstrates the precise data-backed deterioration SS4A reviewers prioritize. SWITRS analysis is complete across all 463 city-street collisions (2015–2025).
-
FHWA Safe System HIN analysis complete. FHWA-weighted Safe System scoring across all 23 HIN corridors and 52 intersections. MAIN ST (15 KSI) and LAUREL RD (11 KSI) are the top-tier anchors for the application narrative and project location workbook.
-
463 crashes analyzed with full multivariate breakdown. Pre/post-COVID KSI trends, 18 fatalities documented, ped/bike/alcohol/dark-condition patterns quantified. 36 ped (9 KSI), 137 dark (23 KSI), 67 alcohol (5 KSI) pools are pre-validated for grant narratives.
-
HIN-to-countermeasure mapping complete — project identification is done. Every HIN corridor matched to FHWA-eligible countermeasures with cost ranges. Remaining work: formal application narrative, project workbook, and self-certification documentation.

What we bring to this application
1 prior HSIP project prove Oakley delivery. H12-04-131 (BCR, $537K). Each provides a direct template for C13 scale-up. Returning applicants with completion history are scored higher.
+0.9% KSI rate change — powerful post-COVID safety narrative. Oakley's severity shift (12.25%→12.36%) demonstrates the precise safety deterioration HSIP C13 prioritizes. SWITRS 2021–2025 data is fully analyzed: 137 dark (23 KSI), 120 speed (8 KSI), 36 ped (9 KSI), 33 bike (9 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 (MAIN ST + LAUREL RD).
C13 portfolio extends every prior HSIP investment in Oakley. Signal/LPI from H12-04-131 scales to citywide LPI+APS at 22 HIN intersections. Each C13 application directly extends proven C12 work.
