An Ordinance Adopting the 2019 Engineering and Tr affic Survey
CITY COUNCIL
Speed limits are set by adopting an Engineering and Traffic Survey (Survey) in accordance with the
California Vehicle Code (CVC) and the California Manual on Uniform Traffic Control Devices (MUTCD).
An approved survey is valid for seven years and can be extended to ten years if the roadway conditions
have not changed. The current Survey was completed in 2012 and adopted in 2013 . A revision to the
California MUTCD was adopted in 2019 that modified allowable reductions in speed limits. Based
upon the expiration of the current Survey and based upon these regulation changes, new speed
survey data was collected during the month of December 2019 to update the study in order to comply
with eve requirements for enforcement.
Recommended Action:
It is recommended that the City Council take public input, close the public hearing and introduce the
Ordinance for first reading by title only, waive further reading, and schedule the adoption for April 7,
2020 .
Discussion:
Sections 22357 and 22358 of the eve give local munici palities the authority to set speed limits below
the maximum speed limits set forth by State law, where such speed lim its are supported by an
Engineering and Traffic Survey. On May 21 , 2013, the City Council approved Ordinance 749 adopting
the 2013 Engineering and Tr affic Survey.
The City's current (2013) Survey was prepared pursuant to the guidelines of the previous CA MUTCD.
This manual allowed for a 5 mph speed reduction based on the roadway geometrics, which i ncludes
horizon t al and vertical curves as well as the roadway cross section . On March 29 , 2019, California
adopted the current MUTCD (2014 CA MUTCD Revision 4), which el i minated the 5 mph reduction
associated with roadway geometrics. The current MUTCD calls for speed limits to be established t o
the nearest 5 mph increment of the 85th percentile speed . For example, if the 85th percentile speed
is 37 mph, the speed limit should be posted at 35 mph. However, if the 85th percentile speed is 38
mph, the speed limit should be posted at 40 mph.
1 of7 March 17, 2020, Item #6
Under the current CA MUTCD, a speed limit may be reduced from the 85th percentile speed by 5 mph
due to a collision rate that is higher than the State average for that type of facility. The reduction is
intended to assist in lowering the collision rate for the roadway segment. A reduction can also be
taken for "non -apparent conditions" such as bicycles, pedestrians, vehicles, and intersections not
readily visible to drivers . However, if the speed limit has been reduced 5 mph due to the collision rate,
it cannot be lowered another 5 mph for "non-apparent conditions". The following traffic and safety
conditions could potentially be used as conditions that are not apparent to drivers: driveways directly
abutting the roadway with frequent turns, insufficient sight distances, mid-block pedestrian and/or
equestrian crossings, and pedestrians and bikers within and along the roadway. Roadway physical
conditions, such as width, curvature, grade and surface conditions, or any other condition readily
apparent to a driver, in the absence of other factors, would warrant a speed reduction, as the basic
rule of section 22350 is sufficient regulation as to such conditions.
The proposed 2019 Survey was prepared using the guidelines of the current CA MUTCD and will
enable our Sheriffs Deputies to use radar for traffic speed enforcement and provide the legal
authority for court requirements.
Attachment B depicts the proposed 2019 Survey with a reference number assigned to each roadway
segment. Out of 51 segments, only one location is being proposed for a speed limit change. Kirkham
Road from Kirkham Court to Scripps Poway Parkway, Segment 16, is being proposed at 35 mph based
on the Survey data collected. The previous posted speed for this segment was 40 mph and the 85th
percentile speed collected was 37 mph, therefore it is recommended that the speed be set at 35 mph .
All of the remaining segments are maintaining the existing speed limits as were determined using the
previous CA MUTCD guidelines. Using the new guidelines did not change the recommended speed
limits.
At its meeting on February 12, 2020, the Traffic Safety Committee (TSC), which includes a
representative from the Sheriffs Department, voted unanimously to support staffs recommendation
to adopt the 2019 Engineering and Traffic Survey. There were no residents at the TSC present for the
speed survey item . Staff received one email regarding the current speed limit on one segment of
roadway prior to the TSC meeting. The email was provided to the committee and discussed during
the meeting.
Environmental Review:
This item is exempt from the requirements of the California Environmental Quality
Act (CEQA), pursuant to Section 15061 (b)(3) of the CEQA Guidelines as it entails adoption of an
Engineering and Traffic Survey and establishing speed limits on several road segments, and there is
no possibility that this will have a significant effect on the environment.
Fiscal Impact:
There are sufficient funds available in the Street Striping Account (411040-4330) to remove and install
the speed legend changes estimated at $500, and in the Sign Maintenance Materials Account (411040-
45300) to replace the speed limit sign changes estimated at $250.
Public Notification:
A Notice of Public Hearing was published in the Poway News Chieftain on Thursday, March 5, 2020.
