Presenter: Chairman Tim Eriksen, Director of Public Works/City Engineer.
Public Comment: James Nosera, Racheal Brazil, Ginger Bushway, Korleen
Boomer, Pinky Kushner, Susan Knopf, Council Member Mulheren.
Possible solutions discussed were the use of a speed radar trailer, speed humps,
making the street a one-way street, blocking the street to through traffic and officer
enforcement by issuing speeding tickets.
Member Sean Kaeser stated Marshall Street does not meet the length or width
requirements for using a speed radar trailer nor is there room to physically place a
speed radar trailer in this area.
Don Brown, Public Works Supervisor stated he is opposed to blocking Marshall
Street because this would greatly limit access by public safety emergency vehicles.
Chairman Tim Eriksen stated the Ukiah city streets are the property of the citizens
and need to be available for public use. Speed humps could make speeding vehicles
lose control quicker and could make the situation a worse one. Bikers and
pedestrians who are walking could be hindered by speed humps. A Measure Y
workshop will be held on July 21 to address pedestrian, bicycle and crosswalk issues
and the Marshall Street concerns will be included.
Motion/Second: Davis/Malugani to ask city engineers to present new options
that are feasible to be used on Marshall Street and present additional
information about options that were discussed.
Motion carried by an all AYE voice vote of the members present.
b. Discussion and Possible Action Regarding STOP sign request— Standley
Street at Spring Street.
Chairman Tim Eriksen recused himself because his neighbor brought this item to
TEC.
Presenter: John Lampi, Vice Chairman.
Vice Chairman John Lampi read a letter from Craig and Jane Rohrbough, 707 W.
Standley St., which requested a four way stop at the intersection of Standley Street
and Spring Street.
Public Comment: Susan Knopf, Pinky Kushner, Lewis Martinelli, John Morris, Buck
Ganter.
Lewis Martinelli stated the STOP signs should be put on Standley Street at Barnes
Street instead of at Spring Street.
John Morris stated it makes more sense to have STOP sign at Barnes because
Barnes is in the middle of Standley Street while Spring Street is very close to the
STOP sign at Dora.
MINUTES of the Traffic Engineering Committee June 13, 2017
Page 2
Member Ben Kageyama stated STOP signs should not be used for speed control.
Putting a STOP sign where it is not warranted causes drivers to ignore that STOP
sign which will cause more problems. He is not in favor of adding a STOP sign.
Traffic calming measures such as narrowing the street or creating offsets in street
alignment could be investigated to slow traffic.
Council Member Mulheren stated the traffic study is performed in 5-year cycles.
City Council recently approved a traffic study and this will be done soon.
Motion made by Member Sean Kaeser to deny putting STOP signs on Standley
Street at Spring Street.
Motion made by Member Neil Davis to have the engineers collect more data,
investigate putting STOP signs on Standley Street at Barnes and research what other
options there are.
The motion dies for lack of a second.
Motion/Second: Kaeser/Lampi to deny putting STOP signs on Standley Street
at Spring Street.
Motion carried by the following roll call votes: AYES: Kaeser, Lampi, Malugani,
Kageyama. NOES: Davis. ABSENT: Meyer, Hewett. ABSTAIN: Schlatter.
RECUSED: Eriksen.

MEMORANDUM
DATE: July 7, 2017
TO: Traffic Engineering Committee
FROM: Rick Seanor, Deputy Director of Public Works
SUBJECT: Discussion and Possible Action Regarding crosswalk and STOP sign request
— North Dora Street at Smith Street
Agenda Item 5a.
REQUEST: The Traffic Engineering Committee (TEC) received a request from Mr. Barry Vogel to
consider crosswalks and STOP signs on North Dora Street at its intersection with Smith Street,
Attachment"A". A photomap of the intersection, Attachment"B", has been provided for reference.
Also provided for the TEC's reference are excerpts from the California Vehicle Code (CVC)
regarding crosswalks,Attachment"C."A page from the Caltrans Highway Design Manual regarding
stopping sight distance is included as Attachment "D". Excerpts from the California Manual of
Uniform Traffic Control Devices (MUTCD) 2014 Edition regarding crosswalks are provided as
Attachment"E". Lastly, for reference, excerpts on STOP signs from the California MUTCD and the
Federal Highway Administration (FHWA) Manual of Uniform Traffic Control Devices 2009 Edition
are provided as Attachment "F".
DISCUSSION: At the subject intersection there are existing STOP signs posted for westbound and
eastbound traffic on Smith Street. North Dora Street at this location has two travel lanes, two
bicycle lanes, and two parking lanes. Smith Street west of N. Dora St. has two-way traffic. Smith St.
east of N. Dora St. is posted for one-way traffic, westbound. During the period (January 1, 2013 -
December 31, 2016) there were no reported collisions at this intersection. On April 30, 2012, the
City's speed zone consultant recorded the ADT (average daily traffic) for N. Dora St. (between
Grove Ave. and the south City limits) at 7,486 vehicles. N. Dora St. is posted for a 30 mph speed
zone, consistent with the speed zone study. Smith Street meets the CVC definition of a residence
district and therefore has a prima facie speed limit of 25 mph.
Staff evaluated the intersection for pedestrian crossing. At this intersection there are "unmarked
crosswalks" at all four approaches. Per the CVC, Attachment "C," drivers are required to yield the
right-of-way to pedestrians within any marked or within any unmarked crosswalk at an intersection.
For the southbound approach, staff measured the stopping sight distance at 280 feet which is more
than adequate for the speed limit of 30 mph, see Attachment "D" and the photomap, Attachment
"B". The other three legs of the intersection have no restrictions on sight distance. Staff reviewed
the California MUTCD sections on crosswalks, Attachment"E." Staff has not observed a significant
volume of pedestrians at this intersection and based on review of the California MUTCD along with
the aforementioned items, does not recommend crosswalks on N. Dora St. at this intersection.
Staff evaluated the intersection for a multi-way STOP application in accordance with the guidance
criteria of the California MUTCD and the FHWA MUTCD (Attachment "F"). N. Dora St. at this
location does not satisfy the guidance criteria therefore STOP signs are not recommended.

Crosswalk and STOP sign request—North Dora Street at Smith Street
July 7,2017
RECOMMENDATION: 1) Deny the request for crosswalks based on engineering staffs review and
evaluation; and 2) Deny the request for STOP signs at the N. Dora St. and Smith Street based on
engineering staffs analysis that the intersection does not meet the warrants for multi-way STOP
control as published in the California MUTCD and the FHWA MUTCD.

Hand delivered
Dear Rick:
This letter replies to your December 14, 2016, email to me regarding the need for a
pedestrian protection at the North Dora and Smith intersection.
I have crossed that intersection often 4 times per day, five days a week for the past 27
years, and observe it frequently. Many other people, especially kids after school cross
there.
Cars and trucks travel south on Dora at increased motor RPMs to come up the incline
from Willow, increasing the risk to pedestrians crossing at Smith. This intersection is
always dangerous yet even more so in the winter months when dusk comes at 5 pm. .
Crosswalks exist at other intersections along Dora that do not even have stop signs.The
greatest protection for everyone -- especially seniors and school children would be to
have a stop sign, or at a minimum, blinking lights set to go on when someone is about
to enter the cross walk. That would be similar to the cross walk on North State Street at
the Fair Grounds. the City of Ukiah should not wait for someone to be injured betore
this needed protection for the people who cross Dora at Smith is implemented.
I am pleased that you will be preparing a report and look forward to receiving it prior to
the TEC meeting. Thank you very much for you time and attention to this matter.
Respectfully yours,
BARRY VOG

Option:
22 A limit line may be placed in advance of a crosswalk where vehicles are required to stop, in compliance with a STOP
(R1-1)sign,traffic control signal or some other traffic control device.
Support:
23 If a marked crosswalk is in place, it would normally function as a limit line.
24 Typical limit line markings are shown in Figure 3B-103(CA).
Section 3B.17 Do Not Block Intersection Markings
Support:
(Jo Refer to CVC 22526 for entering intersection,rail crossing or marked crosswalk.
Option:
of Do Not Block Intersection markings may be used to mark the edges of an intersection area that is in close
proximity to a signalized intersection,railroad crossing,or other nearby traffic control that might cause vehicles
to stop within the intersection and impede other traffic entering the intersection. If authorized by law, Do Not
Block Intersection markings with appropriate signs may also be used at other locations.
Standard:
02 If used,Do Not Block Intersection markings(see Figure 3B18 3B-18(CA))shall consist of one of the
following alternatives:
B.Wide solid white lines that outline the intersection area that vehicles must not block and a white word
message such as DO NOT BLOCK or KEEP CLEAR;
D.A white word message, such as DO NOT BLOCK or KEEP CLEAR,within the intersection area that
vehicles must not block.
03 Do Not Block Intersection markings shall be accompanied by one or more DO NOT BLOCK
INTERSECTION(DRIVEWAY)(CROSSING)(R10-7)signs(see Section 2B.53),one or more DO NOT
STOP ON TRACKS (R8-8) signs(see Section 8B.09),or one or more similar signs.
Section 3B.18 Crosswalk Markings
Support:
of Crosswalk markings provide guidance for pedestrians who are crossing roadways by defining and delineating
paths on approaches to and within signalized intersections,and on approaches to other intersections where traffic
stops.
02 In conjunction with signs and other measures,crosswalk markings help to alert road users of a designated
pedestrian crossing point across roadways at locations that are not controlled by traffic control signals or STOP or
YIELD signs.
03 At non-intersection locations,crosswalk markings legally establish the crosswalk.
Standard:
04 When crosswalk lines are used,they shall consist of solid white lines that mark the crosswalk.They
shall not be less than 6 12 inches or greater than 24 inches in width.
Guidance:
05 If transverse lines are used to mark a crosswalk, the gap between the lines should not be less than 6 feet. If
diagonal or longitudinal lines are used without transverse lines to mark a crosswalk, the crosswalk should be not
less than 6 feet wide.

Part 3 Markings
California MUTCD 2014 Edition Page 683
(FHWA's MUTCD 2009 Edition,including Revisions I &2,as amended for use in California)
06 Crosswalk lines, if used on both sides of the crosswalk, should extend across the full width of pavement or to
the edge of the intersecting crosswalk to discourage diagonal walking between crosswalks (see Figures 3B-17
and 3B-19).
07 At locations controlled by traffic control signals or on approaches controlled by STOP or YIELD signs,
crosswalk lines should be installed where engineering judgment indicates they are needed to direct pedestrians to
the proper crossing path(s).
08 Crosswalk lines should not be used indiscriminately An engineering study should be performed before a
marked crosswalk is installed at a location away from a traffic control signal or an approach controlled by a
STOP or YIELD sign. The engineering study should consider the number of lanes, the presence of a median, the
distance from adjacent signalized intersections, the pedestrian volumes and delays, the average daily traffic
(ADT), the posted or statutory speed limit or 85th-percentile speed, the geometry of the location, the possible
consolidation of multiple crossing points, the availability of street lighting, and other appropriate factors.
09 New marked crosswalks across uncontrolled roadways should include . : • ' :. other measures designed to
reduce traffic speeds, shorten crossing distances, enhance driver awareness of the crossing, and/or provide
active warning of pedestrian presence, -: : • :• • . •.1 • : . • :• : • : • . where the speed

has four or more lanes of travel and an ADT of 1Z000 vehicles per day or greater, advanced yield lines with associated Yield
Here to Pedestrians(R1-5, R1-5a)signs should be placed 20 to 50 ft in advance of the crosswalk, adequate visibility should
be provided by parking prohibitions,pedestrian crossing(W11-2)warning signs with diagonal downward pointing arrow(14/16-
7p)plaques should be installed at the crosswalk, and a high-visibility crosswalk marking pattern should be used(See Figure
38-17(CA)).
Support:
10 Chapter 4F contains information on Pedestrian Hybrid Beacons. Section 4L.03 contains information
regarding Warning Beacons to provide active warning of a pedestrian's presence. Section 4N.02 contains
information regarding In-Roadway Warning Lights at crosswalks. Chapter 7D contains information regarding
school crossing supervision.
Guidance:
ii Because non-intersection pedestrian crossings are generally unexpected by the road user, warning signs (see
Section 2C.50)should be installed for all marked crosswalks at non-intersection locations and adequate visibility
should be provided by parking prohibitions.
Support:
12 Section 3B.16 contains information regarding placement of stop line markings near crosswalk markings.
Option:
13For added visibility, the area of the crosswalk may be marked with white diagonal lines at a 45-degree angle
to the line of the crosswalk or with white longitudinal lines parallel to traffic flow as shown in Figure 3B-19.
14 When diagonal or longitudinal lines are used to mark a crosswalk, the transverse crosswalk lines may be
omitted
Guidance:
14a This type of marking should be used at locations where substantial numbers of pedestrians cross without any other
traffic control device, at locations where physical conditions are such that added visibility of the crosswalk is desired, or at
places where a pedestrian crosswalk might not be expected.
15 If used, the diagonal or longitudinal lines should be 12 to 24 inches wide and separated by gaps of 12 to 60
inches. The design of the lines and gaps should avoid the wheel paths if possible, and the gap between the lines
should not exceed 2.5 times the width of the diagonal or longitudinal lines.
Option:
16 When an exclusive pedestrian phase that permits diagonal crossing of an intersection is provided at a traffic
control signal,a marking as shown in Figure 3B-20 may be used for the crosswalk.

Part 3 Markings
California MUTCD 2014 Edition Page 684
(FHWA's MUTCD 2009 Edition,including Revisions 1 &2,as amended for use in California)
Guidance:
�7 Crosswalk markings should be located so that the curb ramps are within the extension of the crosswalk
markings.
Support:
18 Detectable warning surfaces mark boundaries between pedestrian and vehicular ways where there is no raised
curb. Detectable warning surfaces are required by 49 CFR,Part 37 and by the Americans with Disabilities Act
(ADA)where curb ramps are constructed at the junction of sidewalks and the roadway,for marked and unmarked
crosswalks. Detectable warning surfaces contrast visually with adjacent walking surfaces, either light-on-dark,or
dark-on-light. The"Americans with Disabilities Act Accessibility Guidelines for Buildings and Facilities
(ADAAG)"(see Section 1A.11)contains specifications for design and placement of detectable warning surfaces.
Standard:
19 Crosswalk markings near schools shall be yellow as provided in CVC 21368.See Part 7.
Option:
zo Pedestrian crosswalk markings may be placed at intersections, representing extensions of the sidewalk lines,or on any
portion of the roadway distinctly indicated for pedestrian crossing. Refer to CVC 275.
Guidance.
21 In general, crosswalks should not be marked at intersections unless they are intended to channelize pedestrians.
Emphasis is placed on the use of marked crosswalks as a channelization device.
22 The following factors may be considered in determining whether a marked crosswalk should be used.
A. Vehicular approach speeds from both directions.
B. Vehicular volume and density.
C. Vehicular turning movements.
D. Pedestrian volumes.
E. Roadway width.
F Day and night visibility by both pedestrians and road users.
G. Channelization is desirable to clarify pedestrian routes for sighted or sight impaired pedestrians.
H. Discouragement of pedestrian use of undesirable routes.
I. Consistency with markings at adjacent intersections or within the same intersection.
Option:
23 Crosswalk markings may be established between intersections(mid-block)in accordance with CVC 21106(a).
Guidance:
24 Mid-block pedestrian crossings are generally unexpected by the motorist and should be discouraged unless, in the
opinion of the engineer there is strong justification in favor of such installation. Particular attention should be given to
roadways with two or more traffic lanes in one direction as a pedestrian may be hidden from view by a vehicle yielding the
right-of-way to a pedestrian.
Option:
25 When diagonal or longitudinal lines are used to mark a crosswalk,the transverse crosswalk lines may be omitted.
Standard:
26 However,when the factor that determined the need to mark a crosswalk is the clarification of pedestrian routes
for sight-impaired pedestrians,the transverse crosswalk lines shall be marked.
Option:
27 At controlled approaches, limit lines(stop lines) help to define pedestrian paths and are therefore a factor the engineer
may consider in deciding whether or not to mark the crosswalk.
28 Where it is desirable to remove a marked crosswalk,the removal may be accomplished by repaving or surface treatment.
Guidance:
29 A marked crosswalk should not be eliminated by allowing it to fade out or be worn away.
Support:
30 The worn or faded crosswalk retains its prominent appearance to the pedestrian at the curb, but is less visible to the
approaching road user.
Standard:
31 Notification to the public shall be given at least 30 days prior to the scheduled removal of an existing marked
crosswalk.The notice of proposed removal shall inform the public how to provide input related to the scheduled
removal and shall be posted at the crosswalk identified for removal. Refer to CVC 21950.5

Part 3 - Markings
California MUTCD 2014 Edition Page 685
(FHWA's MUTCD 2009 Edition,including Revisions 1 &2,as amended for use in California)
Option:
32 Signs may be installed at or adjacent to an intersection directing that pedestrians shall not cross in a crosswalk indicated
at the intersection in accordance with CVC 21106(b).
33 White PED XING pavement markings may be placed in each approach lane to a marked crosswalk, except at
intersections controlled by traffic signals or STOP or YIELD signs.
Section 3B.19 Parking Space Markings
Support:
of Marking of parking space boundaries encourages more orderly and efficient use of parking spaces where
parking turnover is substantial.Parking space markings tend to prevent encroachment into fire hydrant zones,bus
stops, loading zones,approaches to intersections,curb ramps,and clearance spaces for islands and other zones
where parking is restricted. Examples of parking space markings are shown in Figure 3B 21 3B-21(CA).
Standard:
02 Parking space markings shall be white.
Option:
03 Blue lines may supplement white parking space markings of each parking space designated for use only by
persons with disabilities.
Support:
04 Additional parking space markings for the purpose of designating spaces for use only by persons with
disabilities are discussed in Section 3B.20 and illustrated in Figure 3B 22 3B-22(CA).The design and layout of
accessible parking spaces for persons with disabilities is provided in the"Americans with Disabilities Act
Accessibility Guidelines (ADAAG)"(see Section 1A.11).
Support:
05 Refer to CVC 22500 through 22522 for parking space markings.
06 Refer to Section 2B.39 for Parking Regulations.

Option:
07 Local authorities may, by ordinance, provide for the establishment of parking meter zones and cause streets and
highways to be marked with white lines designating parking spaces. Refer to CVC Section 22508.
Standard:
08 Where the proposed zones are on State highways,the ordinances shall be approved by Caltrans.
09 Local authorities shall furnish a sketch or map showing the definite location of all parking meter stalls on State
highways before Caltrans approval is given.
Support:
10 The District Directors have been delegated the authority to approve such ordinances.
„The desirable dimensions of parking meter stalls are 8 feet by 24 feet with a minimum length of 20 feet,
Guidance:
12 At all intersections, one stall length on each side measured from the crosswalk or end of curb return should have parking
prohibited.A clearance of 6 feet measured from the curb return should be provided at alleys and driveways.
13 At signalized intersections parking should be prohibited for a minimum of 30 feet on the near side and one stall length on
the far side. See Figure 3B-21(CA).

CHAPTER 7C. MARKINGS
Section 7C.01 Functions and Limitations
Support:
of Markings have definite and important functions in a proper scheme of school area traffic control. In some
cases,they are used to supplement the regulations or warnings provided by other devices, such as traffic signs or
signals. In other instances, they are used alone and produce results that cannot be obtained by the use of any other
device. In such cases they serve as an effective means of conveying certain regulations,guidance,and warnings
that could not otherwise be made clearly understandable.
02 Pavement markings have some potential limitations.They might be obscured by snow,might not be clearly
visible when wet, and might not be durable when subjected to heavy traffic. In spite of these potential limitations,
they have the advantage,under favorable conditions, of conveying warnings or information to the road user
without diverting attention from the road.
Section 7C.02 Crosswalk Markings
Standard:
0oa When transverse crosswalk lines are used,they shall be solid white or yellow,marking both edges of the
crosswalk,except as noted in the Option. Refer to CVC 21368.They shall be not less than 12 inches nor greater than
24 inches in width.
Guidance:
00b If transverse crosswalk lines are used to mark a crosswalk, the gap between the lines should not be less than 6 feet. If
diagonal or longitudinal lines are used without transverse lines to mark a crosswalk, the crosswalk width should not be less
than 6 feet.
00c Crosswalk lines on both sides of the crosswalk should extend across the full width of pavement or to the edge of the
intersecting crosswalk to discourage diagonal walking between crosswalks.
of Crosswalks should be marked at all intersections on established routes to a school where there is substantial
conflict between motorists, bicyclists, and student movements; where students are encouraged to cross between
intersections; where students would not otherwise recognize the proper place to cross;or where motorists or
bicyclists might not expect students to cross (see Figure 7A-1).
02 Crosswalk lines should not be used indiscriminately. An engineering study considering the factors described
in Section 3B.18 should be performed before a marked crosswalk is installed at a location away from a traffic
control signal or an approach controlled by a STOP or YIELD sign.
03 Because non-intersection school crossings are generally unexpected by the road user, warning signs (see
Sections 7B.11 and 7B.12)should be installed for all marked school crosswalks at non-intersection locations.
Adequate visibility of students by approaching motorists and of approaching motorists by students should be
provided by parking prohibitions or other appropriate measures.
Support:
04 Section 3B.18 contains provisions regarding the placement and design of crosswalks, and Section 3B.16
contains provisions regarding the placement and design of the stop lines and yield lines that are associated with
them. Provisions regarding the curb markings that can be used to establish parking regulations on the approaches
to crosswalks are contained in Section 3B.23.
Support:
05 Examples of school area signing, markings,flashing beacons and overhead school signs are shown in Figures 7B-1(CA),
7B-5(CA), 7B-4 through 7B-6 and Figures 7B-101(CA)through 7B-104(CA).
06 Refer to CVC 21368 for crosswalks near schools.
Standard:
07 Whenever a marked pedestrian crosswalk has been established in a roadway contiguous to a school building or
school grounds,it shall be yellow. If any one of the crosswalks is required to be yellow at an intersection,then all
other marked pedestrian crosswalks at that intersection shall also be yellow.Refer to CVC 21368.

Section 2B.06 STOP Sign Applications
Guidance:
of 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(see Sections 213.08 and 21109).
02 The use of STOP signs on the minor-street approaches should be considered if engineeringjudgment indicates
that a stop is always required because of one or more of the following conditions:
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 a
STOP sign have been reported within a I2-month period, or that five or more such crashes have been
reported within a 2-year period. Such crashes include right-angle collisions involving road users on the
minor-street approach failing to yield the right-of-way to traffic on the through street or highway.
Support:
of The use of STOP signs at grade crossings is described in Sections 8B.04 and 8B.05.
Section 2B.07 Multi-Way Stop Applications
Support:
oi Multi-way stop control can be useful as a safety measure at intersections if certain traffic conditions exist.
Safety concerns associated with multi-way stops include pedestrians,bicyclists,and all road users expecting other
road users to stop. Multi-way stop control is used where the volume of traffic on the intersecting roads is
approximately equal.
02 The restrictions on the use of STOP signs described in Section 2B.04 also apply to multi-way stop
applications.
Guidance:
of The decision to install multi-way stop control should be based on an engineering study.
04 The following criteria should be considered in the engineering study for a multi-way STOP sign installation:
A. Where traffic control signals are justified, the multi-way stop is an interim measure that can be installed
quickly to control traffic while arrangements are being made for the installation of the traffic control signal.
B. Five or more reported crashes in a 12-month period that are susceptible to correction by a multi way stop
installation. Such crashes include right-turn and left-turn collisions as well as right-angle collisions.
C. Minimum volumes:
1. The vehicular volume entering the intersection from the major street approaches(total of both approaches)
averages at least 300 vehicles per hour for any 8 hours of an average day;and
2. The combined vehicular,pedestrian, and bicycle volume entering the intersection from the minor street
approaches (total of both approaches)averages at least 200 units per hour for the same 8 hours, with an
average delay to minor-street vehicular traffic of at least 30 seconds per vehicle during the highest hour;
but
3. If the 85th-percentile approach speed of the major-street traffic exceeds 40 mph, the minimum vehicular
volume warrants are 70 percent of the values provided in Items 1 and 2.
D. Where no single criterion is satisfied, but where Criteria B, C.1, and C.2 are all satisfied to 80 percent of the
minimum values. Criterion C.3 is excluded from this condition.
Option:
05 Other criteria that may be considered in an engineering study include:
A.The need to control left-turn conflicts;
B.The need to control vehicle/pedestrian conflicts near locations that generate high pedestrian volumes;
C. Locations where a road user,after stopping,cannot see conflicting traffic and is not able to negotiate the
intersection unless conflicting cross traffic is also required to stop; and

oi The YIELD(RI-2)sign(see Figure 2B-1)shall be a downward-pointing equilateral triangle with a wide
red border and the legend YIELD in red on a white background.
Support:
02 The YIELD sign assigns right-of-way to traffic on certain approaches to an intersection. Vehicles controlled by
a YIELD sign need to slow down to a speed that is reasonable for the existing conditions or stop when necessary to
avoid interfering with conflicting traffic.
Section 2B.09 YIELD Sign Applications
Option:
oi YIELD signs may be installed:
A. On the approaches to a through street or highway where conditions are such that a full stop is not always
required.
B. At the second crossroad of a divided highway,where the median width at the intersection is 30 feet or greater.
In this case,a STOP or YIELD sign may be installed at the entrance to the first roadway of a divided
highway,and a YIELD sign may be installed at the entrance to the second roadway.
C. For a channelized turn lane that is separated from the adjacent travel lanes by an island,even if the adjacent
lanes at the intersection are controlled by a highway traffic control signal or by a STOP sign.
D. At an intersection where a special problem exists and where engineering judgment indicates the problem to be
susceptible to correction by the use of the YIELD sign.
E. Facing the entering roadway for a merge-type movement if engineering judgment indicates that control is
needed because acceleration geometry and/or sight distance is not adequate for merging traffic operation.
Standard:
0.1A YIELD(RI-2)sign shall be used to assign right-of-way at the entrance to a roundabout.YIELD signs
at roundabouts shall be used to control the approach roadways and shall not be used to control the
circulatory roadway.
of Other than for all of the approaches to a roundabout,YIELD signs shall not be placed on all of the
approaches to an intersection.
Section 2B.10 STOP Sign or YIELD Sign Placement
Standard:
oi The STOP or YIELD sign shall be installed on the near side of the intersection on the right-hand side of
the approach to which it applies.When the STOP or YIELD sign is installed at this required location and
the sign visibility is restricted,a Stop Ahead sign(see Section 2C.36)shall be installed in advance of the
STOP sign or a Yield Ahead sign(see Section 2C.36)shall be installed in advance of the YIELD sign.
02 The STOP or YIELD sign shall be located as close as practical to the intersection it regulates,while
optimizing its visibility to the road user it is intended to regulate.
1$^ YIELD signs shall not be erected upon the approaches to more than one of the intersecting streets.Refer to CVC
21356.
na STOP signs and YIP D signs shall not he mounted on the same post.
04 No items other than inventory stickers,sign installation dates,and bar codes shall be affixed to the
fronts of STOP or YIELD signs,and the placement of these items shall be in the border of the sign.
05 No items other than official traffic control signs, inventory stickers,sign installation dates,anti-

MEMORANDUM
DATE: July 7, 2017
TO: Traffic Engineering Committee
FROM: Rick Seanor, Deputy Director of Public Works p
SUBJECT: Discussion and Possible Action Regarding STOP sign request—West Mill
Street at South Oak Street
Agenda Item 5b.
REQUEST: The Traffic Engineering Committee (TEC) received a request from Mr. John Mistry,
owner of the Prime Market at 295 W. Mill St. to post STOP signs on W. Mill St. at its intersection
with S. Oak Street, Attachment "A". Mr. Mistry noted in his request that the valley gutters on
each side of Mill Street have the effect of causing drivers to slow suddenly when crossing the
intersection. This, according to Mr. Mistry, leaves the slowing vehicles exposed to cross traffic
and potential collisions from vehicles on W. Mill St.
DISCUSSION: A photomap of the intersection, Attachment "B", has been provided for
reference. Please note the locations of the valley gutters on the photomap as well as the location
of the red curb— no parking zones on both sides of all approaches to the intersection. Vehicles
crossing at this intersection have the added benefit of the 8-foot wide parking lanes when
crossing W. Mill St. In other words, a car slowing for the valley gutters would be clear of the
travel lanes when crossing the intersection. In addition, drivers have the obligation to make sure
they have safe clearance from cross traffic before entering the intersection. For reference,
excerpts on STOP signs from the California Manual of Uniform Traffic Control Devices(MUTCD)
2014 Edition and the Federal Highway Administration (FHWA) Manual of Uniform Traffic Control
Devices 2009 Edition are provided as Attachment "C".
At the subject intersection there are existing STOP signs posted for northbound and southbound
traffic on S. Oak Street. W. Mill St. at this location has two lanes, one eastbound and one
westbound, with no restrictions on parking with the exception of the red curb at the approaches
to the intersection. During the period (January 1, 2013 - December 31, 2016) there were five
reported collisions at this intersection. The following is a summary of the reported collisions:

May 4, 2016 broadside NB vs. EB 21802A
Please find attached the respective sections of the California Vehicle Code (CVC) which were
cited in the collisions,Attachment"D". On S. Oak St., in accordance with CVC 21802(a), drivers
must stop at Mill Street and only cross when they can proceed with reasonable safety to clear
the intersection.
On April 30, 2012, the recorded ADT(average daily traffic)for W. Mill St. (between Highland Dr.
and S. State St.) was 2,824 vehicles. On May 10, 2012, the recorded ADT for N. Oak Street
(between Perkins St. and Low Gap Road)was 1,599 vehicles.Although this ADT count does not
include the intersection location, staff believes there is a similar volume of vehicles on this
section of S. Oak St. Staff evaluated the W. Mill St. / S. Oak St. intersection for a multi-way
STOP application in accordance with the guidance criteria of the California MUTCD and the
FHWA MUTCD (Attachment "C"). W. This intersection does not satisfy the guidance criteria
therefore STOP signs are not recommended.
RECOMMENDATION: Deny the request for STOP signs on W. Mill St. at S. Oak Street based
on engineering staff's analysis that the intersection does not meet the warrants for multi-way
STOP control as published in the California MUTCD and the FHWA MUTCD.

Subject: Request for Stop Signs on West Mill &Oak St.
Ben,
I received a request from the business owner of the Prime Market located at 295 West Mill Street.
The request is for 'STOP'signs to be placed at both the westbound and eastbound lanes of West Mill Street at its intersection of
Oak St.
I believe this request is valid and deserves consideration at the Traffic Engineering Committee. If you visit this intersection you
will see that West Mill Street has a deeper than normal Valley Gutter on both sides of the street.The owner expressed to me
that there have been many accidents at this intersection and that the Valley Gutter condition causes drivers to have to slow
considerably after entering the intersection,which leaves the vehicle on Oak Street exposed to drivers on West Mill,often
unexpectedly.
I tend to agree with this,as I too have had close calls there.
The owners Name is John Mistry and he is copied on this email.
Could you please get in touch with him and review his request, and if possible assist him with bringing this forward to the TEC.
Best Regards,
•

needed because acceleration geometry and/or sight distance is not adequate for merging traffic operation.
Standard:
02 A YIELD(R1-2)sign shall be used to assign right-of-way at the entrance to a roundabout.YIELD signs
at roundabouts shall be used to control the approach roadways and shall not be used to control the
circulatory roadway.
al Other than for all of the approaches to a roundabout,YIELD signs shall not be placed on all of the
approaches to an intersection.
Section 2B.10 STOP Sign or YIELD Si n Placement
Standard:
oi The STOP or YIELD sign shall be installed on the near side of the intersection on the right-hand side of
the approach to which it applies. When the STOP or YIELD sign is installed at this required location and
the sign visibility is restricted,a Stop Ahead sign(see Section 2C.36)shall be installed in advance of the
STOP sign or a Yield Ahead sign(see Section 2C.36)shall be installed in advance of the YIELD sign.
02 The STOP or YIELD sign shall be located as close as practical to the intersection it regulates,while
optimizing its visibility to the road user it is intended to regulate.
o,D YIELD signs shall not be erected upon the approaches to more than one of the intersecting streets.Refer to CVC
21356.
in STOP signs and YIFI D signs shall not he mounted on the same post.
04No items other than inventory stickers,sign installation dates,and bar codes shall be affixed to the
fronts of STOP or YIELD signs,and the placement of these items shall be in the border of the sign.
05 No items other than official traffic control signs, inventory stickers,sign installation dates,anti-
vandalism stickers,and bar codes shall be mounted on the backs of STOP or YIELD signs.
06 No items other than retroreflective strips(see Section 2A.21)or official traffic control signs shall be
mounted on the fronts or backs of STOP or YIELD signs supports.

Section 2B.06 • ' • 4, • • ' '• • -17)Pali Ge*
Guidance:
01 At intersections where aft,!!stop is not necessary at all consideration should first he given to using less
restrictive measures such as YIELD signs(see Sections 213.08 and 2B.09).
02 The use of STOP signs on the minor-street approaches should be considered if engineering judgment
indicates that a stop is always required because of one or more of the following conditions:
A. The vehicular traffic volume.son the through street or highwas exceed 6,000 chic les per das;
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
a STOP sign have been reported within a 12-month period, or that five or more such crashes have been
reported within a 2-year period. Such crashes include right angle collisions involving road users on the
minor-street approach failing to yield the right of wco. to traffic on the through street or highwas
Support:
03 The use of STOP signs at grade crossings is described in Sections 8B.04 and 8B.05.
Section 2B.07 u .- A : ei . . 11
Support:
01 Multi-was stop control can be useful as a safets measure at intersections if certain traffic conditions(Am.
Safety concerns associated with multi-way stops include pedestrians,bicyclists,and all road users expecting
other road users to stop. MUILi-Is ay stop control is used where the volume of traffic on the intersecting roads is
approximately equal.
02 The restrictions on the use of STOP signs described in Section 2B.04 also apply to multi-way stop applications.
Guidance:
03 The decision to install multi-way stop control should be based on an engineering studs
04 The following criteria should be considered in the engineering study for a multi war STOP sign installation:
A. Where traffic control signals are justified, the multi way stop is an interim measure that can he
installed quickly to control traffic while arrangements are being made for the installation of the traffic
control signal.
B. Five or more reported crashes in a 12 month period that are susceptible to correc lion Its a multi way stop
installation. Such crashes include right turn and left turn collisions as well as right angle collisions
C. Minimum volumes:
1. The vehicular volume entering the intersection from the major street approaches (total of both
approaches)averages at least 300 vehicles per hour for any 8 hours of an aserage day;and
2. The combined s.ehicular,pedestrian,and bicycle volume entering the intersection from the minor
street approaches(toted of both approaches)averages at least 200 units per hour for the sante 8
hours, rtith an average delay to minor-street vehu War traffic of at least 30 seconds per vehicle
during the highest hour;but
3. If the 8.51' percentile approach speed of the major street traffic.exceeds 40 mph, the minimum
vehicular volume warrants are 70 percent of the values provided in Items I and 2.
D. Where no single criterion is satisfied, but where Criteria B, CI, and C.2 are all satisfied to 80 percent of
the mininuun values. Criterion C.3 is excluded from this condition.
Option:
05 Other criteria that may be considered in an engineering study include
A. The need to control left-turn conflicts;
B. The need to control Nehicle/pedestrian conflicts near locations that generate high pedestrian OIUMCS
C. Locations where a road user,after stopping,cannot see conflicting traffic and is not able to negotiate the
intersection unless conflicting cross traffic is also required to stop;and
a An intersection of two residential neighborhood collector(through)streets of similar design and operating
characteristics where multi-way stop control would improve traffic operational characteristics of
the intersection
