CITY MANAGER' S REPORT
JANUARY 8, 2024 CITY COUNCIL REGULAR MEETING
ITEM: PUBLIC HEARING ( PUBLISHED NOTICE) TO
CONSIDER AN ORDINANCE AMENDING THE SPEED
LIMITS IN THE CITY OF LATHROP, TITLE 10
VEHICLES AND TRAFFIC, CHAPTER 10. 08 SPEED
LIMITS, SECTION 10. 08. 030 SPEED LIMITS OF THE
LATHROP MUNICIPAL CODE
RECOMMENDATION: City Council to Consider the Following:
1. Hold a Public Hearing; and
2. Introduction and First Reading of an Ordinance
of the City Council of the City of Lathrop
Amending Section 10. 08. 030 Speed Limits" of
the Lathrop Municipal Code
SUMMARY:
The California Vehicle Code ( CVC) Sections 22357 through 22364 and 40800 through 40808 require an Engineering and Traffic Survey ( Survey) to establish or update a legally enforceable speed limit on most California roads. Speed limits must be established within one year of acceptance of major City streets, as the current posted speed limit is based on design criteria, not a Survey.
Staff conducted the Surveys for the purpose of establishing legally enforceable speed limits on local streets. The proposed amended Ordinance ( Attachment A) sets enforceable speed limits for various streets within the City.
Staff requests that City Council hold a public hearing, consider all information and public testimony and, if determined to be appropriate, adopt an Ordinance amending Section 10. 08. 030 " Speed Limits" of the Lathrop Municipal Code.
BACKGROUND:
Pursuant to CVC Sections 22357 through 22364 and 40800 through 40808, law enforcement can only enforce speed limits posted on regulatory signs if they are listed identically in City Municipal Code and are based on a valid and current Survey prepared by a California- licensed traffic engineer.
Speed limit signs currently posted on these segments represent design speed, a calculation conducted to determine an initial speed limit for a road based upon its geometry, number of lanes, surrounding land use and other factors.

ANUARY 8, 2024 CITY COUNCIL REGULAR MEETING
PUBLIC HEARING ( PUBLISHED NOTICE) TO CONSIDER AN ORDINANCE AMENDING THE SPEED LIMITS IN THE CITY OF LATHROP, TITLE 10 VEHICLES AND TRAFFIC, CHAPTER 10. 08 SPEED LIMITS, SECTION 10. 08. 030 As traffic volumes on the subject streets have increased to a level supporting the collection of speed data to determine enforceable speed limits, City staff conducted the Surveys. The proposed amended Ordinance ( Attachment A) reflects the findings of the Surveys and could be utilized to set enforceable speed limits for various streets in the City of Lathrop that have yet to be surveyed.
The CVC governs how Surveys are conducted and describes the basis for the proposed speed limits. Data is collected on actual vehicle speed data from at least 100 or more free flowing vehicles per segment in a three- hour period. The traffic engineer then processes the data to determine important parameters such as the 85th percentile speed, 10 mile per hour ( mph) pace, and percentage of vehicles following the current posted speed limit. The traffic engineer also considers physical and environmental factors of the segment, such as the number of residential driveways, the proximity to schools, sun glare, roadway width, etc.
As required by the CVC, the recommended speed limit is determined by rounding to the nearest 5 mph increment from the 85t'' percentile speed. Based on physical and environmental factors, the traffic engineer has the ability to reduce the recommended speed by 5 mph if the justification for doing so is documented in the Survey.
CVC also states that Surveys are valid for seven years. Therefore, these Surveys will expire on February 1, 2031. Surveys may also be extended by a traffic engineer for seven ( 7) years depending upon criteria such as significant changes in roadway alignment, traffic volumes, and surrounding land use.
As a function of the Surveys conducted by City staff, proposed speed limits for segments of City streets bounded by associated nodes are summarized in Table 1, below. The complete Surveys for each street are provided as Attachment B.
