TRAFFIC CONDITIONS ON ROSS ROAD
REOUEST
On April 3, 1997, Council directed staffto work with residents to develop a recommended
plan for the installation of road bumps on the segment of Ross Road between Oregon
Expressway and Colorado Avenue (see Attachment 1). Council voted to refer this item
to the Policy and Services Committee. This report presents the background information.
RECOMMENDATIONS
Staff recommends that Council direct staff to work with residents to develop a plan for
the installation of road bumps on the segment 6fRoss Road between Oregon Expressway
and Colorado Avenue, and return with a Budget Amendment Ordinance to fund the
installation.
POLICY IMPLICATIONS
In 1991, Council approved a citywide program for installation of road bumps on local
residential streets, including procedures and criteria, based on a successful test of road
bumps in the Midtown area (see Attachment 2). This program gives residents a procedure
by which they can request road bumps, and it allows staff to determine which requests
should go forward for Council approval, without staff having to present every case to
Council for consideration. Even when a particular request meets all Council-established
criteria, staff is still required to obtain Council approval. Even though staff cannot
recommend road bumps unless all the criteria are met, Council may override the criteria
and approve bumps under circumstances it deems appropriate. Two criteria, in particular,
were purposely set high in order to limit road bump installation to those situations where
there is dear, factual evidence that speeding has become an actual hazard (minimum
CMR:320:97 Page 1 of 3
existing speed of 32 mph and minimum of six speed-related accidents in three years). In
this way, road bumps would be used only in the most serious situations, minimizing the
bumps’ cumulative impacts on maintenance, street resurfacing, and Fire Department
response times.
Since the program was established in 1991, staff has received and evaluated 17 official
requests for road bumps. None of the requests met the accident criterion, with the result
that staffdid not approve any of the 17. Other than the bumps in the Midtown area (which
preceded the establishment of the citywide program), Council has approved the
installation of bumps in only two locations, neither of which fully met the required criteria.
One ease was the Lytton Avenue Neighborhood Traffic Management Plan, in which
Council approved a set of bumps as an. integral part of the overall plan, which also
included other traffic management devices. In the second case, a set of bumps was
installed on Bryant Court as part of a subdivision approval. Even in the Midtown area,
where bumps were first installed, the now-established criteria would not have been fully
satisfied.
Approval of road bumps on Ross Road would continue the precedent for installation of
bumps in situations where not all of Council’s criteria have been met.
EXECUTIVE SUMMARY
As explained in staff’s response to Mr. Jones’ June 10, 1996 letter (Attachments 3 and
4), eight of the nine criteria are met for road bumps on Ross Road between Oregon
Expressway and Colorado Avenue. Only the accident criterion is not met (no speed-
related accidents were recorded for that segment of Ross Road during the analysis
period). Staff therefore denied the residents’ request. Residents felt strongly enough about
their situation to contact Council for special consideration in overriding the criteria.
Council received numerous letters from Ross Road residents, for its April 3 discussion.
Those letters, as well as others received recently, are included separately in the packet.
The traffic volume on this segment of Ross Road, 2600 vehicles per day, is higher than
most typical local residential streets in Palo Alto. Eighty-fifth percentile speeds on this
segment of Ross Road range from 30 to 34 mph, depending on direction and location.
Speeds on local residential streets in Palo’ Alto are typically around 32 mph or less.
Considering the congestion at the nearby Oregon/Middlefield intersection, staff believes
that a primary cause of the above traffic conditions on Ross Road is that some drivers on
Oregon Expressway and Middlefield Road use Ross Road and other local streets to
bypass that intersection. Even though there are no police records of speed-related
accidents on Ross Road, residents are obviously concerned that accidents could occur,
CMR:320:97 Page 2 of 3
and present many anecdotal experiences of speeding, near misses, and pets being killed.
Residents are also concerned about reduced quality of life due to the impacts of traffic
volumes and speeds. Road bumps reduce speeds, may discourage some through traffic,
and are relatively inexpensive compared to other physical traffic calming measures. Other
than the lack of speed-related accidents and the impacts of road bumps discussed above,
there are no reasons why road bumps cotdd not be installed on this street segment, should
Council so desire.
FISCAL IMPACT
Approximately 5 to 7 bumps would be needed to noticeably reduce speeds on this
segment of Ross Road. At a cost of approximately $3,200 per bump, including signing
and striping, the project would cost about $23,000. There is no funding for road bumps
in the current budget or capital improvement program. Staff will-return with a Budget
Amendment Ordinance from the General Fund Budget Stabilization Reserve, if Council
so directs.
ENVIRONMENTAL ASSESSMENT
An environmental assessment would be prepared at the time a specific project were
brought to Council for approval.

FROM:Council Members Fazzino and Eakins
SUBJECT: Traffic Conditions of Ross Road
For a longtime, residents of the section of Ross Road between Oregon Expressway and
Colorado Avenue have expressed serious concerns about the speed of traffic and
increased volume of traffic along that section of Ross Road. The problems that Ross Road
is experiencing are very similar to problems experienced during the 1980s by Middlefield
Road’s other major parallel street, Cowper Street. As you know, the Council installed
speed bumps on Cowper at that time to address their traffic speed and volume concerns.
Both Ross Road and Cowper Street are used as alternatives by drivers to get to and from
the Midtown area.
Collectively the residents approached the City last year to request installation of road
bumps to reduce travel speeds. City staff reviewed their request and concluded that this
section of Ross Road meets eight of the nine criteria established by Palo Alto for
installation of road bumps. Failure to meet the accident criteria (minimum of six speed-
related accidents in three years) precludes staff from proceeding with the installation of
road bumps under current city procedures, unless otherwise directed by Council. Copies
of a letter request from residents and staff’s response are attached for reference.
More recently, we met with a group of residents who live along this segment Of Ross Road,
and it is apparent that they have very serious continuing concerns about the safety of their
children, their pets, themselves and others and look to the Council for help. We believe
that their situation warrants further consideration and action. They reported to us several
incidents of accidents, near accidents, and the deaths of several pets due to high speed
traffic. This block of Ross Road experiences traffic volume p.roblems because it is used
as an alternative to Middlefield Road to get to the freeway or to Midtown and points south,
and high speed traffic problems because it is located right off Oregon, is a wide street, and
lacks a significant tree canopy or other traffic calming measures.
Therefore, we recommend that the Council direct staff to work with residents to come up
with a recommended plan for the installation of road bumps for the segment of Ross Road
between Oregon Expressway and Colorado Avenue. We view this as an interim solution
until such time as a comprehensive plan is developed to address the traffic problems
associated with Middlefield and other parallel roads to assure a fair distribution of traffic.

ROAD BUMP PROGRAM
ATTACHMENT 2
speed bump road bump
BACKGROUND
A road bump is an artificially created, relatively gentle rise in the pavement of a local
residential street. The above figure compares a road bump to a speed bump commonly
found in parking lots. The purpose of road bumps is to lower speeds on local residential streets.
Several years ago, road bumps were installed on a test basis in the Midtown neighborhood
of Palo Alto, and have successfully reduced.traffic speeds and volumes on those streets (a
common side effect of road bumps is the reduction of traffic volumes on the streets with the
bumps).
-In March 1991, the City Council approved the use of road bumps as a tool for potential use
in appropriate situations. Road .bumps may be installed only when it is desired to reduce
speeds on local residential streets and when specific criteria can be met (please refer to the
attached Procedures and Guidelines). Road. bumps are certainly not the answer to all
speeding problems, and they are not appropriate for all situations. Rather, they are another
tool for managing speeds on residential streets. They have a number of disadvantages,
including delay to emergency vehicles, potential diversion of traffic to other residential
streets, increased noise, general inconvenience to the driving public, and an unattractive
appearance.
Road bumps are still experimental in the sense that no State or national guidelines have
been issued for their use or design. Thus, there is considerable variation in road bump
installations among various cities. If State or national guidelines were issued, Palo Alto’s
guidelines might need to be modified to conform. Our guidelines might need to be modified
anyway, in the course of our o.wn experience with road bumps.
HOW TO GET ROAD BUMPS ON YOUR STREET
If you live on a local residential street in Palo Alto, and you believe that thereis a speeding
problem on your street, you may wish to request consideration of the installation of road bumps
to help reduce speeds on your street. Before you make your request, please read the attached
Procedures and Guidelines, especially the five "Basic Criteria" listed on page 2. These are
five of the many criteria which your street must meet .b.’efore the City could consider
installing road bumps, and they are things you may already know about your street. Item
1 under "Basic Criteria" requires that your street be a local residential street. The attached
figure shows which streets in Palo Alto are no.._At local residential streets (i.e., almost all other
streets ar~e local residential streets). We advise you to see and experience the Midtown road
bumps located on Cowper Street south of Oregon Expressway, and on Marion and Colorado
Avenues between Cowper and Middlefield Road. You should be comfortable with the look
and feel of road bumps in front of your own home. You should also have some idea of
whether or not your neighbors would be comfortable with road bumps, possibly in front of
their own homes, as two-thirds of them would eventually have to sign a petition supporting
the road bumps (Procedures and Guidelines, page 3).
Your written request for road bumps should be sent to: Chief Transportation Official,
Transportatign Division, P.O. Box 10250, Palo Alto, CA 94303. The request should include
your name, address, and daytime telephone number. Please include a brief desci’iption of
your concern about speeding, and the approximate limits of the area on your street that you
are concerned about (e.g., "2400 block", or between "A" and "B" streets). You must live
within or adjacent to the portion of the street where you are requesting road bumps. Within
about one week, you will be notified in writing that your request has been received. In
about six weeks, you will be notified either (a) that your street does not qualify for road
bumps (refer to Procedures and Guidelines, page 1, item 2); or (b) that your street meets
the initial guidelines and that you are required to circulate a neighborhood petition (refer
to Procedures and Guidelines, page 2, ,item 3). Ultimately, if your request meets all the
necessary criteria, public meetings will be held, and the final decision would be made by the
City Council (refer to Procedures and Guidelines, pages 1-2, items 5-8).
QUESTIONS?
If you need more information, please contact Mr. Carl Stoffel, Transportation Division, at
329-2552. Additional .copies of these Procedures and Guidelines are available, as well as
staff reports providing background information about the road bump program.

PROCEDURES AND GUIDELINES FOR APPLICATION ANDDESIGN OF ROAD BUMPS
IN PALO ALTO
A.Administrative Procedures
o
o
A request for road bumps must originate from a resident of the
street on which the bump is desired. That request may be
forwarded through the neighborhood association representing
that area. Alternatively, staff may suggest to a resident who
has filed a complaint relating to his or her street that rba~
bumps may be an option for addressing the complaint (in which
case the next step would be skipped).
After receipt of a request, staff will determine if the street
meets the Basic Criteria listed in Section B, and, if data is
readily ~available, Operational Criteria (i) and (3). A
cursory determination will also be made of whether any of the
guidelines in Section C would preclude the installation, of
bumps. If the street does not meet these criteria, staff will
so inform the requestor in writing, and advise the Police
Department that a speed complaint has been received that may
need enforcement action.
If the street does meet the criteria identified in A(2), the
requestor will be required to submit a petition (forms
provided by the city) which establishes the extent of
neighborhood support (two-thirds, as explained in Section B).
After staff receives and verifies the petition, staff will
gather traffic data in order to determine if the street meets
the Operational Criteria listed in Section B. If the street
does not meet the Operational Criteria, staff will so inform
the .requestor in writing, and advise the Police Department
that~ a speed complaint has been received that may need
enforcement action.
If the street meets all the criteria listed in Section B,
staff will conduct a more thorough evaluation, including:
The logical length of the street segment where bumps
should be installed and the number and location of
potential road bumps on this segment will be determined.
The extent of the area where traffic diversion might
occur will be determined. The amount of traffic
diversion from the eligible ("primary") street to other
("secondary,). streets in this area will be estimated.
Traffic speed and volume data on these secondary streets
will be collected.
If nece~ ry, mitigation measures ~ 0r the secondary
streets w±±l be proposed. If road bumps are proposed as
mitigation measures, the secondary streets shall meet as
many of the eligibility criteria listed in Section B as
possible.
A neighborhood meeting for residents of the primary an~
secondary streets will be held.
A report for City Council will be prepared. It is
anticipated that this report would be referred to the
Policy and Procedures Committee.
After Policy and Procedures Committee review, the request will
be forwarded to the city Council for program, but not funding,
approval.
If City Council approves the road bump request, the project
will be considered for funding approval by inclusion in the
Capital Improvement Program (CIP) internal staff screening
process which normally begins in December of each year.
If approved during the screening process, the road bump
project will be.included in the CIP which the City Manager
recommends to the City Council. In May of each year, the
recommended CIP is transmitted to the City Council for
consideration and approval, via public hearings before the
Finance and Public Works Committee. (Note that a road bump
project may meet all Criteria and guidelines, but could still
fail to receive funding approval in the CIP.)
Road bumps may be considered for removal under a similar
procedure. ~.

Mr. David E. Jones III
and Residents of Ross Road

Palo Alto, CA 94303
Dear Mr. Jones:
This is in response to the June 10, 1996, letter from you and all the residents of
the 2400 and 2500 blocks of Ross Road regarding speed and traffic conditions on
Ross Road between Oregon Expressway and Moreno Avenue, and requesting
installation Of road bumps. You have discussed thi~ issue several times On the
telephone with Carl Stoffel, and I appreciate your understanding that we have not
been able to respond earlier.
As you and Mr. Stoffel discussed, Palo Alto has a program for installation of road
bumps on local residential streets, based on procedures and criteria approved by
the City Council in 1991, and he has sent you our packet detailing the program.
The criteria were designed to be strict, as there are some undesirable aspects of
road b .umps that warrant their usage to be limited to situations with demonstrated
safety problems. According to the City’s procedures, all nine criteria must be met
in order for the Transportation Division to recommend installation of bumps,, with
final approval and authorization of funding required from the City Council.
We evaluated the section of Ross Road between Oregon Expressway and
Colorado Avenue, which is a longer segment than is the subject of your request,
because we have received prior complaints about the segment of Ross Road
between Moreno and Colorado Avenues. The Oregon to Colorado segment meets
the first five basic criteria for road bumps in that (I) it is a local residential street;
(ii) the speed limit is 25 mph; (iii), the segment is long enough; (iv) it is not a
truck, bus, or emergency vehicle access route; and (v) its grade is less than 5
percent. As is obvious from your letter, the neighborhood support criterion is met
in the 2400 and 2500 blocks of Ross Road.
The final three criteria concem volume, speed, and number of accidents, for which
we gathered data in July. The 24-hour volume (ADT) was measured for three days
in each of two locations (2400 and 2700 blocks), with a resulting average count
of 2600 ADT in both locations, meeting the criterion that the volume be between
250 Hamilton Avenue

500 and 4000 ADT. Speed surveys were conducted northbound and southbound
at the same two locations. In the 2400 block, 85th-percentile speeds were found
to be 34 mph (northbound) and 32 mph (southbound). In the 2700 block, speeds
were 30 mph (northbound) and 33 mph (southbound). These speeds, when
averaged, meet the minimum speed criterion of 32 mph. Finally, accident history
was examined for this segment of Ross Road between January 1, 1992 and
October 31, 1996. Four accidents were reported to the Police Department during
this nearly five-year period, none of which was speed related. This does not meet
the criterion of a minimum of six speed-related accidents in three years..While
we can understand your desire to have road bumps installed on Ross Road, you
can see that your request does not meet the required minimum criterion for
accidents.
For your information, there are locations where road bumps have been approved
or installed in Palo Alto where the above nine criteria have not all been met.
These were special eases that involved City Council review and approval of the
bumps in the context of a larger project--a neighborhood area study and a
residential subdivision project. Since 1992, we have received approximately five
requests and inquiries for road bumps from residents of the 2400 to 2700 blocks
of Ross Road (some of whom were the same people who signed your letter). It
is typical for speeds and volumes on local streets to be higher than usual close to
an intersection with a major arterial, such as Oregon Expressway. In this case,
congestion at the Oregon/Middlefield intersection is probably causing some
.drivers to bypass the intersection. The City has a planned improvement project
that would substantially improve the operation of the intersection, thus reducing
the advantage to drivers of taking shortcuts. However, funding is not yet available
for this project. ~
Please be assured that the City is concerned about traffic safety, and recently
initiated several safety-related programs. These include additional Police
Department traffic team members, use of motorcycles for enforcement, a
neighborhood speed watch program (wherein residents may use Police
Department radar guns to identify speeders), and others. We will forward a copy
of this letter to Lieutenant Don Hartnett with a request for the.Police Department
to provide additional speed enforcement on Ross Road. You may wish to contact
him about the speed watch program or other aspects of the traffic safety program
(329-2449).

In summary, installation of road bumps on Ross Road does not meet all of the
City Council approved criteria, and we have notified the Police Department of
your neighborhood’s concerns about speeding. Again, thank you for your
patience, and for bringing your concerns to our attention.
