2109-4 326 Altamont Dr – Request to remove handicap parking space in front of residence (Bryan Ong; 326 Alta Monte Dr; 510-502-4948)
• Previous request for disable parking space was approved back in 2001 and space was removed in 2007. From the research, the space was installed as the requestor has visibility issues with park cars while backing out of the driveway
• The residence does have a wide driveway and garage.
• Engineering followed up with the requestor and it was noted that paratransit bus needs to make contact the with curb, so requester’s mother can be
transferred onto the bus’s lift safely. Bus driver won’t lower lift in the street as it is unsafe. SamTrans Paratransit also mentioned that it depends on the safety of the client and the vehicle.
• TAC recommends installing the disable parking space.
• TAC will log this DP space into our records.
• A work order will be sent to our maintenance division

Chris DiPrima 425 Larch Ave 847-204-2923
At the intersection of Airport Blvd. and Sister Cities Blvd., affecting eastbound traffic:
The auxiliary traffic signal high-mounted atop the signal pole on the northwest corner of theintersection is no longer visible to eastbound traffic due to tall trees and foliage. (See red circle inFigure 1). Based on a quick Google Maps estimate, the auxiliary signal head is only visible about425' before the stop bar (Figure 2). This is at most about 100' farther than the normal signal heads,but there is also an issue where drivers can see the right turn signal head (blue circle in Figure 1)before they can see the thru-traffic heads.
Several sets of tire tracks regularly laid down on this portion of road suggest that regular emergency/panic stops are happening along this approach, suggesting the risk of a catastrophic high-speedrear-end collision.
Since this is downhill, I am guessing that the 85th percentile speed is at least 45 MPH, which wouldleave drivers only 6.4 seconds to properly identify the auxiliary signal and come to a stop if the signalis red.
Requesting installation of a California MUTCD W89 Activated Blank-Out warning beacon for driversto "PREPARE TO STOP" when approaching a red signal.

Jeff,
This is an e-mail from the Parking Enforcement Officer Ram
Good morning Cpl. De La Cruz,
I am responding to the parking complaint at 805 Linden Avenue.
When I arrived, there were no vehicles with placards in the painted green. However, I did
observe a painted blue curb behind the green curb.
That vehicle is a gray Acura DUV (9BHW088) and registered at 811 Linden Avenue. The
handicap placard in the windshield is valid and registered to owner of the Acura (handicapped
placed #K120456). It is possible that the RO may park their vehicles in the painted green as
they do have multiple cars.

Jeff,
The only limitation of parking with a valid ADA placard are crosshatched spaces, red curbs,
yellow commercial curbs, white curbs, tow away zones. With a valid ADA placard, they are
allowed to park on green curbs (regardless of the time 2 hours or 24 minutes), on-street
metered with no payment. I will have a parking enforcement officer check on the vehicle/
vehicles to see if they have a valid ADA placard. If they do not have a valid ADA placard
(expired) they are subject to a citation and/or confiscation of the placard.
I believe that business has asked TAC in the past to change the parking from 24 minutes to 2
hours, which we did. The reason for the change in time was because the police department
was citing their customers, after the 24-minute violation.
I will let you know later today if the person possessed a valid ADA placard.

Subject: Imperial Beauty Salon - 805 Linden Ave
Hello TAC,
I’ve been working with the business owner at 805 Linden Ave, Imperial Beauty Salon, on various business support
services as her business is struggling. One item she has mentioned to me is the challenge with the 2-hour parking spot
in front of the business, and is requesting if the City can change this spot to a 24-minute spot. A residential neighbor
next door is parking within the spot with two interchangeable vehicles for the duration of the day, using the same ADA
placard in the window, and is abusing the intent of the space due to the lack of residential parking spaces next door.
She’s asking if this can be changed to 24 minutes, which would be consistent with a couple of other similar 24-minute
spots in front of a few other businesses within a two block area also on Linden. It seems like this is the only 2-hour spot
in the area directly in front of a commercial use and is being used for a residential use.
Happy to provide additional info if needed.
Thanks for your consideration,

Here are the CA-MUTCD requirements for STOP on minor street.
A consultation with Police Chief and a Resolution by the City Council is required (per Muni Code). Also, Per SSF Muni
Code, the adjacent properties have to be informed.
Per the California Manuel on Uniform Traffic Control Devices (CA-MUTCD), Section 2B.06, STOP Sign
Application, the use of STOP signs on minor-street approaches should be considered if engineering judgement
indicates that a stop is always required because of one or more of the following:
A. The vehicular traffic volumes on the through street or highway exceed 6,000 vehicles per day;
B. A restricted view exists that requires road users to stop in order to adequately observe
conflicting traffic on the through street or highway, and/or;
C. Crash records indicate that three or more crashes that are susceptible to correction by the
installation of STOP sign have been reported within 12-month period, or that five or more such
crashes have been reported within a 2-year period. Such crashes include right-angel collisions
involving road users on the minor-street approach failing to yield the right-of-way to traffic on
the through street or highway.
CA-MUTCD Section 2B.06, STOP Sign Application, further states that:
At intersections where a full stop is not necessary at all times, consideration should first be given to using less
restrictive measures such as YIELD signs.
If Maple is not defined as through fare then one of the conditions A, B or C (above) has to apply. Otherwise it will be
hard to justify installing Stop. Other option is Yield.

Hi Senor Fakhry,
Thanks for the info! I highly doubt it’s designated as a “through” street. In fact I didn’t know of this designation existed
at all! So I am inclined to simply have the striping and signage placed as part of an existing contract… if not prohibited by
CVC.

Dear Mayor, councilman,
There are so many accidents on this section of Avalon Drive. 8/20/2022 happened again.
The curve and the speeding cars always crashed into the cars parking.
We need additional speed bumps, stop signs and street lights in this section.
Please address this issue in the council meeting and help.

Good morning,
My neighbor, Arlene Cain, petitioned The Traffic Advisory
Committee to install speed bumps on Sutton Avenue. This
application was denied on October 7, 2022.
However, our street was repaved a few years ago, and the barriers
that were removed during this process were never
reinstalled. They were white cement blocks and Bot Dots to keep
drivers in their lane as they negotiated the turn at each corner
(Longford/Sutton and Sutton/Dunman).
If you require, I will send a video of the vehicles that cross over the
turn lane and travel at full speed, even faster than allowed in a
residential neighborhood, by traveling in the middle of the street.
This is very dangerous.
I am requesting Mrs. Cain's application be reviewed to modify it to
reinstall the corner turn barriers we used to have that the City
neglected to reinstall for the safety of our neighborhood.

Stop Sign Information
Each year, the City receives numerous requests to install stop signs. This document has
been designed to answer some of the most common questions residents have about stop
signs and when installation is appropriate.
What is the purpose of a stop sign?
Many people believe stop signs are designed to reduce speed. However, the main
purpose of a stop sign is to assign right-of-way at intersections.
Can stop signs be used to reduce traffic speeds or cut-through traffic?
No, studies have shown stop signs are ineffective speed control devices. Vehicles often
increase speed after a stop sign to make up for “lost time”. Stop signs are also
ineffective at reducing the amount of cut-through traffic on a street.
If stop signs can’t reduce speed or cut-through traffic, what can?
Concerns about speeding vehicles or cut-through traffic can be addressed by the City’s
Neighborhood Traffic Management Program (NTMP).
If your street qualifies for the NTMP, traffic calming measures such as speed humps or
traffic circles can be considered for installation. These devices, and many others, have
proved successful at reducing traffic speeds or the amount of cut-through traffic.
To learn more, contact the City at the telephone number or email address listed at the
end of this document.

What harm would another stop sign do?
When an excessive number of stop signs are installed or where the need to control right-
of-way is doubtful, traffic congestion can increase with little or no gain in safety. In fact,
safety could even be reduced.
Pedestrian and rear-end accidents also tend to increase, as the stop signs present a
false sense of security.
Excessive use of stop signs also reduces the credibility of all stop signs, as many
motorists become frustrated and either speed up after the stop sign or run through it.
In some cases, stop sign violations can occur up to 25% of the time.
Where can stop signs be installed?
Stop signs can be installed at entrances to certain through streets or where a stop sign
warrant study indicates the need for a stop sign.
What is a stop sign warrant?
Stop sign warrants are used to determine whether or not a stop sign should be installed.
Warrants analyze:
• The number of vehicles at an intersection
• Accident history
• Vehicular and pedestrian conflicts
• Visibility
• Unusual conditions including:
o High concentrations of pedestrians or vehicles.
o Regular use of the intersection by children, the elderly or disabled.
What costs are involved with installing stop signs?
The installation of a stop sign is inexpensive, but associated costs are not. The following
costs must be considered before a stop sign is installed:
• Cost of the stop sign warrant study.
• Sign maintenance.
• Extra fuel consumed when cars accelerate after a stop sign.
• Air pollution increases as a result of increased fuel consumption.
• Residents living near stop signs experience increased air and noise pollution.

What else can be done?
Often, simple solutions may improve a situation. The City may need to trim trees or
bushes to uncover signs or to increase sight distances (on private property this is the
responsibility of the property owner).
The Traffic Engineer may also be able to install warning signs near an intersection.
However, if you believe there is a chronic traffic concern in your area, contact the Police
Department at the number listed below.
Contact Information
For more information on stop signs or other traffic related issues, contact the City Traffic
Engineer or the Analyst for the Transportation Division at (650) 903-6311. You can also
send an email to: [email protected].
To report missing or damaged traffic signs, call Public Services at
(650) 903-6329.
If you would like to report traffic violations, contact the Police Department’s Traffic
Hotline at (650) 903-6146.

Traffic Signal Information
There are approximately 120 signalized intersections in Mountain View, including City,
State and County owned signals. This document answers commonly asked questions
about City owned traffic signals, how they operate and how new signal locations are
selected.
What is the Purpose of a Traffic Signal?
A traffic signal is designed to provide orderly movement of traffic through an intersection.
Requests for New Signals
New signals are requested by residents, property owners and from various public and
private sources. Before a signal can be installed, a traffic signal warrant study must be
performed to determine if the minimum criteria can be met.
Signal warrant studies will analyze:
• The number of vehicles and pedestrians using an intersection.
• Accident history.
• Proximity to major traffic routes, other traffic signals, schools and parks.
• Unusual considerations such as road curvature.
Funding for New Signals
The City will also take cost into account when new signals are considered. The typical
cost for a new signal is approximately $250,000-$350,000.
TAC 2209-B
62
The City’s Capital Improvement Program (CIP) funds most new traffic signals.
Developers, as part of residential or commercial construction projects, also finance traffic
signals.
Benefits and Disadvantages of Traffic Signals
A traffic signal can change traffic patterns in and around an intersection. When evaluating
potential signal locations, the City takes into account all possible benefits and
disadvantages. These include:
Benefits
• Interrupts heavy traffic on major streets to permit cross traffic, including
pedestrians and bicyclists, to move safely through an intersection.
• Moves traffic more efficiently, allowing a larger number of vehicles to travel
through the intersection.
• Reduces certain types of accidents, especially broadside accidents, at some
intersections.
Disadvantages
• Increases overall travel time as a result of additional stops.
• May result in increased number of rear end collisions.
• May cause diversion of traffic onto other streets as a result of motorists avoiding
the signal.
• Increases vehicle wear from additional stops and starts.
Traffic Signal Equipment
Traffic signals are comprised of more than just the light poles with red, yellow and green
lights. They contain two important pieces of equipment which help direct the flow of
traffic in an efficient manner.
Traffic controller: This is the “brain” of the signal, which is programmed to operate the
signal’s various phases.
Loop detectors: These are wire circuits cut into the road just before the painted limit line.
Metal objects, such as a car or bicycle, passing over or stopping on them, activates the
detector and tells the traffic controller vehicles are present or are proceeding through the
intersection. Video detection is used at some intersections.
Signal Timing
All traffic signals in Mountain View are traffic actuated. The loop detectors and video
detection mentioned earlier allow the traffic controller to monitor traffic and assign the
TAC 2209-B
63
most “green” time to the heaviest traffic movements and provide sufficient crossing time
for bicyclists and pedestrians.
Signal Preemption
Many traffic signals are equipped with devices allowing emergency vehicles to “preempt”
the signal to pass on a green light.
Interconnected Signals
On some streets, traffic signals are linked together, allowing groups of vehicles to
progress through several signals.
In Mountain View, several streets, including Shoreline Boulevard and Grant Road are
equipped with this system.
El Camino Real, owned and operated by Caltrans, is also interconnected. Central
Expressway, which is owned and operated by Santa Clara County, is also interconnected.
Signal Operations
Flashing Red: On a flashing red, all motorists must stop at the intersection as if stop
signs are present.
Flashing Yellow: When a traffic signal is flashing yellow, motorists proceed with caution
through the intersection.
Dark Signals: If a traffic signal is out, treat it as a stop sign.
Manual Control: If traffic is directed by a police officer, their instructions override any
traffic signal.
City Contact Information
To report any malfunctioning signal within the City of Mountain View, including signals on
Central Expressway and El Camino Real, contact the City Traffic Engineer (650) 903-6311
during normal business hours. You can also send an email to
[email protected].
The Traffic Engineer can answer your questions about traffic signals and other traffic
related issues.
To report malfunctioning signals after hours, please contact the City’s Emergency
Communications Center at (650) 903-6395.
