SUBJECT: TRAFFIC REVIEW FOR RED CURB REQUEST FOR 3248 JACKSON AVENUE
The City of Rosemead received a "General Curb Marking Request" from the homeowner of 3248 Jackson
Avenue. The resident is requesting red curb to be installed on both sides of their driveway. The resident
reported that due to vehicles parking too close to their driveway and the volume of traffic on Jackson
Avenue, they have difficulty exiting out of their driveway. In response to this request and on behalf of the
city, engineering staff completed a traffic review and recommended the appropriate measures based on
this request. The traffic review included an analysis of existing roadway conditions as well as an
examination of guidelines within the CAMUTCD (California Manual on Uniform Traffic Control Devices),
CVC (California Vehicle Code) and as well as the City of Rosemead's curb marking policy and procedure.

RECOMMENDATIONS
After a thorough review of existing field and traffic conditions and per the California Manual on Uniform
Traffic Control Devices (CAMUTCD), California Vehicle Code (CVC), City of Rosemead Curb Marking Policy
and engineering judgement, it is recommended to install red curb on the east side of Jackson Avenue, on
the north side of the driveway at 3248 Jackson Avenue. The installation of red curb north of this driveway
will ensure vehicles do not encroach into the resident's driveway and will increase visibility for residents
backing onto Jackson Avenue. The installation of Red Curb follows guidelines as found in the City of
Rosemead's Curb Marking Policy as well as the California Vehicle Code (CVC) 22507. Per City of
Rosemead's Curb Marking Policy, "A typical driveway red tipping installation could include between 2 to
5 feet of red curbing on either side of the driveway'.
1. RED CURB INSTALLATION: Install Red Curb: 2 feet of red curb in each direction in front of the
residence of 3248 Jackson Avenue should be painted red indicating no stopping, standing, or
parking, whether the vehicle is attended or unattended to deter vehicles from blocking the
driveway access, as shown in Figure 3.
2. REMOVE AND REPLACE ADDRESS NUMBERING: The address curb numbering for 3248 Jackson
Avenue should be removed and repainted outside of the red curb area, as shown in Figure 3.
Please refer to Figure 3 for a conceptual exhibit representation of the proposed recommendations.

Traffic Review for Red Curb Request for 3248 Jackson Avenue
Red Zones are necessary for the smooth and safe operations of public transit, fire
responders. and in general. all motorists. Red Zones are also necessary for other areas
where a parked car will limit visibility for traffic, pedestrians. or bike nders.
In lieu of Red Zones, or in some cases to supplement those zones, no -parking signage
may be installed and enforced so long as at least two signs are visible from any portion
of the parking area -
No -parking zones can be installed in any area of the City where the presence of parked
vehicles at the curb creates an unsafe situation for vehicular or pedestrian traffic or
reduces operational efficiency at a particular location to unacceptable levels.
Critical Red Zones
Critical Red Zones are installed for the benefit of the entire community. They can
be installed on any intersection corner to maintain safe and efficient visibility or
on certain segments of streets, where narrow street widths impede the flow of
traffic or create unsafe driving conditions. Thus, when it is warranted by the
Public Works Department, red curbing can be installed on the comer of any
intersection to maintain safe and efficient vehicular maneuverability, or on certain
segments of streets where narrow street widths cause vehicular operations to
degrade to unaoceptable conditions. The red curb installations discussed above
are considered cnbcal red zones, where parking restrictions are necessary to
maintain safe roadway and traffic conditions.
Certain locations may be painted red, without the need of Traffic Commission
review or City Council approval, where parking is restricted at any time as is
required by federal, state, or local law (Le. parlung in from of fire hydrants,
approprialety signed and marked public transit bus slops, etc-).
Driveway Red Tiooino
Driveway red tipping is a special type of red zone that is installed at driveways.
Short sections of red curbing, typically requested by property owners. can be
installed on either side of a driveway to promote better maneuverability into and
out of the driveway and to improve visibility from the driveway. The amount of
red tipping will be installed in a way that minimizes the loss of existing on -street
parking spaces.
Driveway red tipping can be installed to eliminate non-standard parking spaces
(less than 18 feet) between driveways; a condition that sometimes leads to one
or both driveways being partially blocked by parked vehicles.
A typical driveway red tipping installation could include between 2- to 5 -feet of
red curbing an either side of the driveway. However, if there is a possibility to
park motorcycles or micro -vehicles, those locations shall be preserved and
striped appropriately. There are limited situations where the length of red curb
installed at a location could be adjusted on a case-by-case basis depending on
other factors such as adjacent parking and operations at adjacent driveways.
