(Ord. 934-03 § 1)
In accordance with state law and the California Vehicle Code, the city engineer is authorized to determine traffic control devices within or adjacent to intersections to indicate the course to be traveled by vehicles turning at such intersections, and is authorized to locate and indicate more than one lane of traffic from which drivers of vehicles may make right or left hand turns.
(Ord. 934-03 § 1)
In accordance with state law and the California Vehicle Code, the city engineer is hereby authorized to determine which intersections the city shall preclude vehicles from making a right, left, or U-turn, and the public works director shall place proper signs to indicate such prohibition at all applicable intersections.

The public works director shall install and maintain the stop signs at such intersections. Signage shall conform with the Manual of Uniform Traffic Control and the Caltrans Traffic Manual.
A. 
Arterial and Collector Streets. The Manual of Uniform Traffic Controls and the Caltrans Traffic Manual shall be used as the warrant guidelines for multi-way stop sign control at intersections where the average intersection traffic exceeds five hundred vehicles per hour during the highest volume traffic period of eight hours of the day, with two hundred vehicles per hour entering from the side streets. Additionally, stop signs shall be placed at those intersections having five or more correctable accidents within the latest twelve months period if other less restrictive measures have been unsuccessful in preventing accidents.
B. 
Residential Streets. The warrant guidelines as adopted and used by the Los Angeles County department of public works shall be used for residential streets adjacent to schools and local residential neighborhood streets.
1. 
A residential intersection adjacent to a school, meeting the following criteria below, is a candidate for multi-way stop controllers.
a. 
Volume. The combined pedestrian and vehicular unit volumes entering the intersection from all approaches should average at least three hundred fifty units per hour during any two hours of a school day, and the combined pedestrian and vehicular unit volumes entering the intersection from the minor or lower volume street should average at least one hundred forty units per hour during the same two hours.
b. 
Pedestrian Volume. The pedestrian volume across the uncontrolled leg(s) must average at least twenty pedestrians per hour during these same two hours.
2. 
A local residential neighborhood intersection meeting two of the criteria below is a candidate for multiway stop controllers.
a. 
Volume. Total intersection volume is equal to or greater than three hundred vehicles per hour average for any seven hours (may include pedestrians), and side street volume is equal to or greater than one-third of the total intersection volume for the same seven hours.
b. 
Collisions. Three or more accidents in a twelve-month period or four accidents in a twenty-four month period.
c. 
Visibility. Intersection sight distance is less than one hundred fifty feet.
d. 
Speed. The 85th percentile speed on the uncontrolled street is greater than thirty-five miles per hour.
e. 
Volume Adjustment Factors. Volume criteria reduced to sixty percent of the above volume threshold, if all the following are met: there is residential frontage with a twenty-five mile per hour speed limit, neither street is more than forty feet wide, no other stop signs or traffic controls are located within six hundred feet of the proposed location for the stop sign, and the intersection is located near an activity center and twenty-five pedestrians cross through the intersection during any consecutive two hour period.
(Ord. 934-03 § 1)
No person shall deface, mark, alter, damage, mar, draw on or in any other way destroy, ruin, disfigure or impair any placed pavement or freshly painted marking or traffic signage on any street or sidewalk when a barrier, sign, delineation or any other traffic control device is in place clearly marking off the area to pedestrian and/or vehicle traffic.

The public works director shall place and maintain appropriate devices, marks or lines upon the surface of the roadway to designate such crosswalks.
B. 
When Pedestrians Must Use Crosswalks. No pedestrian shall cross a roadway other than by a crosswalk in any business district.
