1 INTRODUCTION
The Fixing America's Surface Transportation Act (FAST) was signed into law on
December 4, 2015. The Highway Safety Improvement Program (HSIP) is one of the programs
created by the FAST Act. HSIP is a federal-aid program that aims to achieve a significant reduction
in fatalities and serious injuries on public roadways. HSIP provides municipalities with funding
for projects that have the sole purpose of reducing crashes and improving roadway safety. Local
HSIP projects must be identified on the basis of crash severity, crash potential, crash rate, or other
data-supported means. Beginning 2022, a Local Road Safety Plan (LRSP) will be required for an
agency to be eligible to apply for HSIP funds. Due to this requirement and the County¡¯s
commitment to improving transportation safety for all users on local roadways, the Sonoma
County Department of Transportation and Public Works has developed this LRSP.
The purpose of this LRSP report is to identify ¡®hotspot¡¯ collision areas on roadways within the
County and explore potential short term and long term corrective measures that may reduce
collision rates and improve roadway safety. This report focuses on the past five years (2015-2019)
of collisions within the County. During this timeframe, the County has experienced 5,542 reported
collisions, 78 of which were fatal (resulting in 84 fatalities total, i.e. some collisions resulted in
multiple fatalities). Based on the five years of data, there has been an average of 1,108
collisions/year and 16 fatalities/year on the County roadways.
For comparison, unincorporated Napa County had 1,675 collisions resulting in 20 fatalities and
unincorporated Marin County had 1,975 collisions resulting in 19 fatalities for the same time
period. Compared to these two counties, Sonoma County has a much higher number of collisions
and fatalities. However one should be cautious when drawing conclusions from these statistics,
due to the counties being different sizes, having different population densities, commute patterns,
and different total miles of roadway.

Figure 1: Map of all collisions within unincorporated county
Sonoma County has approximately 1,400 miles of roadway under its jurisdiction. This report
focuses solely on roadways within the unincorporated portions of the County and therefore all
analyses and statistics are based on collisions that occurred on unincorporated County roadways.
Collisions from cities and other jurisdictions are not included in this report.
This report is divided into the following sections:
? visions and goals of the LRSP,
? safety partners,
? existing County efforts to improve roadway safety,
? collision data analysis methodologies,
? presentation of results from analyses,
? further discussion of results based on hotspots identified,
? implementation of proposed improvements,
? and envisioned future iterations of this LRSP.

2 VISION & GOALS
Sonoma County¡¯s vision for this LRSP is to advance roadway safety within the County by reducing
fatal and serious injury collisions.
The goals of the LRSP are:
? Identify areas of concern
? Apply proven safety solutions systematically to reduce fatal and severe crashes.
? Reduce the number of fatal crashes to zero by 2030.
? Implement a holistic approach within the County to promote traffic safety and Zero Deaths
strategies that involves multiple divisions (land development, traffic, design, etc.).
3 SAFETY PARTNERS
A vital part of developing and implementing a LRSP is partnering with other agencies and
jurisdictions and seeking public input. Additional public input will be included in the LRSP
based on the Vision Zero program being spearheaded by Sonoma County Health Services and
the Transportation Authority. The following list of partners were consulted in the development of
this plan:
?
?
?
?
California Highway Patrol (CHP)
County of Sonoma
o Permit and Resource Management Department (PRMD)
o Department of Transportation and Public Works (DTPW)
Engineering
Traffic
Land Development
Road Maintenance
o Department of Health Services
o Transportation Authority (SCTA)
Sonoma County Bicycle and Pedestrian Committee
Sonoma County Vision Zero Advisory Committee
4 EXISTING EFFORTS
Sonoma County is continuously evaluating the safety of the roadways to reduce the number of
collisions. The following are actions that the Department of Transportation and Public Works
currently undertakes to improve roadway safety:
?
?
?
?
?
?
?
?
Weekly traffic meetings between staff and the department director to discuss current
roadway issues and potential solutions.
Inclusion of bicycle and pedestrian improvements into roadway improvement projects and
paving projects when feasible.
Recent installation of rumble strip and high reflective striping on Lakeville Rd.
Coordination with CHP to target high collision areas and discuss possible solutions.
Radar trailer program to target high speeding areas.
Proactive approach with land development projects to implement safety improvements.
Proactive sign installation and replacement approach.
Retro-reflectivity testing and replacement program for sign panels.
