MEMORANDUM
DATE: April 14, 2009
TO: Traffic Engineering Committee
FROM: Rick Seanor, Deputy Director of Public Works
SUBJECT: Discussion and Possible Action Regarding Parking on Hamilton Drive
and Hospital Drive
Agenda Item 5a.
REQUEST: Staff received a request from Connie Diamond requesting a no parking zone
on Hamilton Drive. Please refer to Attachment "A" which is a copy of an email requesting
the no parking zone. Please note Attachment "B" for a photomap of the Hamilton Drive -
Hospital Drive area.
DISCUSSION: Ms. Diamond has noted in her request that motor homes, recreational
vehicles, and semi-truck trailers park for extended periods of time along Hamilton Drive and
Hospital Drive. On previous occasions, staff observed these types of vehicles parking along
Hamilton Drive. On April 10, 2009, staff visited the area and found no vehicles parked along
Hamilton Drive. However, staff observed a semi-truck trailer and a pickup with camper
trailer parked along Hospital Drive just east of Hamilton Drive. Please refer to the attached
photo, Attachment "C".
RECOMMENDATION: Staff is submitting this report for review and discussion by the TEC.
Staff has provided the following options for consideration:
1. Recommend approval of a no parking zone (10 pm to 6 am) for Hamilton Drive and
for Hospital Drive east of Hamilton Drive and refer to City Council for formal action.
2. Refer to staff for further analysis.
3. Take no action.

Flag Status: Red
Hi Rick
I am requesting that the Traffic Engineering Committee, consider posting No Parking from
some time in the evening to early morning on Hamilton and Hospital Drive.
For several years vehicles have been parking overnight and for extended periods of time---
motor homes, recreational vehicles, semi-truck trailers.
I have filed many complaints with the City of Ukiah, but the problem continues. If the
area is posted, then the vehicles will know that there is no overnight parking.
Presently the motor homes that parked there throughout the week, leave on Saturday and
return on Sunday night--- because the City tickets vehicles on Sundays. Also there are
two semi trailer parked on the street, one has been there for several weeks.
I would appreciate any support that your committee can give in bringing this issue before
the City Council Thanks Connie Diamond

MEMORANDUM
DATE: April 14, 2009
TO: Traffic Engineering Committee
FRO : Rick Seanor, Deputy Director of Public Works
SUBJECT: Discussion and Possible Action Regarding Request for STOP signs on East
Gobbi Street at Oak Manor Drive
Agenda Item 5b.
REQUEST: The Traffic Engineering Committee (TEC) received a letter from residents on Oak Manor
Drive requesting posting of STOP signs on East Gobbi Street at Oak Manor Drive. Please refer to the
request, Attachment "A". A photomap of this intersection, Attachment "B", has been provided for
reference. A photograph of the intersection is provided as Attachment "C".
DISCUSSION: The residents cited recent traffic accidents as well as vehicles travelling at high rates
of speed as reasons to support the requested STOP signs. At this intersection there is an existing
STOP sign for southbound traffic on Oak Manor Drive. East Gobbi Street from Leslie Street to Oak
Manor Drive is posted for a 30 mph speed zone. East of Oak Manor Drive, East Gobbi Street is
posted with a 25 mph speed zone sign. The City of Ukiah is currently working on the design for a
project to realign the intersection of East Gobbi Street - Oak Manor Drive - Babcock Lane. The
project is scheduled to be advertised for bids this summer. Once constructed, Oak Manor Drive and
Babcock Lane will align north to south.
COLLISION HISTORY: Staff reviewed the Statewide Integrated Traffic Records System (SWITRS) to
determine if there were any collisions at the intersection of East Gobbi Street at Oak Manor Drive.
During the period from January 1, 2004 through June 30, 2007 there was only one reported collision at
the intersection. However, staff is aware of two accidents at this intersection within the last year. In
one accident a vehicle turning from Gobbi Street onto Oak Manor Drive ran into a street light. Another
accident involved a vehicle running into the house located at the corner of East Gobbi Street and Oak
Manor Drive.
STOP SIGNS: Attached for reference are selected pages from the Manual on Uniform Traffic Control
Devices (MUTCD) and the MUTCD 2003 California Supplement regarding multi-way STOP sign
applications (Attachment "D"). Also, please note Attachment "E", Section 7061 of the City Code which
authorizes the city traffic engineer (TEC) to post STOP signs. This intersection is unusual in the fact
that Gobbi Street is slightly offset as it transitions past Oak Manor Drive. Based on review of the
MUTCD, STOP signs are not warranted on East Gobbi Street at Oak Manor Drive.
RECOMMENDATION: Staff is submitting this report for review and discussion by the TEC. Staff has
provided the following options for consideration:
1. Deny the request for a STOP sign on East Gobbi Street at Oak Manor Drive.
2. Refer to staff for further analysis.

RE: Request for Installation of New Stop Signs
Corner of Oak Manor Drive & E. Gobbi Street
Dear Committee Members,
%
)4+
We, the residents and homeowners of the Oak Manor neighborhood, are requesting that 2 stop signs
be installed on eastbound and westbound directions of E. Gobbi Street at the corner of Oak Manor
Drive.
Cars traveling eastbound on E. Gobbi, turning left (northbound) onto Oak Manor Drive, consistently
drive too fast. Residents attempting to back out of their driveways onto Oak Manor Drive and school
children using these sidewalks are constantly at risk of being hit by these fast moving cars.
Recently, there have been 2 serious car crashes on this corner. One car crashed into and took out the
light pole located on the sidewalk, and another car actually crashed into the house damaging the
studs and drywall in two bedrooms and taking out 6 feet of the concrete foundation.
Will you please give some attention to this mater, before some person gets hurt?
Thank-you,

Notes: @
1. Larger signs may be used when appropriate.
2. Dimensions are shown in millimeters followed by inches in parentheses and are shown as width x height.
Section 26.05 STOP Sign APpiications
Guidance:
STOP signs should be used if engineering judgment indicates that one or more of the following conditions
exist:
A. Intersection of a less important road with a main road where application of the normal right-of-way rule
would not be expected to provide reasonable compliance with the law;
B. Street entering a through highway or street;
C. Unsignalized intersection in a signalized area; and/or
D. High speeds, restricted view, or crash records indicate a need for control by the STOP sign.
Standard:
Because the potential for conflicting commands could create driver confusion, STOP signs shall not be
installed at intersections where traffic control signals are installed and operating except as noted in Section
4D.01.
Portable or part-time STOP signs shall not be used except for emergency and temporary traffic
control zone purposes.
Guidance:
STOP signs should not be used for speed control.
STOP signs should be installed in a manner that minimizes the numbers of vehicles having to stop. At
intersections where a full stop is not necessary at all times, consideration should be given to using less restrictive
measures such as YIELD signs (see Section 213.08).
Sect. 213.05 November 2003
'4 2003 Edition Ari v.4,. V1'11 -tv t ~1"Pi` t G C t71'l~t g ~ ~ Page 2B-7
Once the decision has been made to install two-way stop control, the decision regarding the appropriate
street to stop should be based on engineering judgment. In most cases, the street carrying the lowest volume of
traffic should be stopped.
A STOP sign should not be installed on the major street unless justified by a traffic engineering study.
Support:
The following are considerations that might influence the decision regarding the appropriate street upon
which to install a STOP sign where two streets with relatively equal volumes and/or characteristics intersect:
A. Stopping the direction that conflicts the most with established pedestrian crossing activity or school
walking routes;
B. Stopping the direction that has obscured vision, dips, or bumps that already require drivers to use lower
operating speeds;
C. Stopping the direction that has the longest distance of uninterrupted flow approaching the intersection; and
D. Stopping the direction that has the best sight distance to conflicting traffic.
The use of the STOP sign at highway-railroad grade crossings is described in Section 8B.08. The use of the
STOP sign at highway-light rail transit grade crossings is described in Section 10C.04.
Section 28.06 STOP Sign Placement.
Standard:
The STOP sign shall be installed on the right side of the approach to which it applies. When the STOP
sign is installed at this required location and the sign visibility is restricted, a Stop Ahead sign (see Section
20.29) shall be installed in advance of the STOP sign.
. The STOP 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.
STOP signs and YIELD signs shall not be mounted on the same post.
Guidance:
Other than a DO NOT ENTER sign, no sign should be mounted back-to-back with a STOP sign in a manner
that obscures the shape of the STOP sign.
Support:
Section JA.16 contains additional information about separate and combined mounting of other signs with
STOP signs..
Guidance:
Stop lines, when used to supplement a STOP sign, should be located at the point where the road user should
stop (see Section 3B.16).
If only one STOP sign is installed on an approach, the STOP sign should not be placed on the far side of the
intersection.
Where two roads intersect at an acute angle, the STOP sign should be positioned at an angle, or shielded, so
that the legend is out of view of traffic to which it does not apply.
Where there is a marked crosswalk at the intersection, the STOP sign should be installed in advance of the
crosswalk line nearest to the approaching traffic.
Option:
At wide-throat intersections or where two or more approach lanes of traffic exist on the signed approach,
observance of the stop control may be improved by the installation of an additional STOP sign on the left side of
the road and/or the use of a stop line. At channelized intersections, the additional STOP sign may be effectively
placed on a channelizing, island.
Support:
Figure 2A-2 shows examples of some typical placements of STOP signs.
Section 213.07 Multivvay Stmp A.pptications
Support:
Multiway stop control can be useful as a safety measure at intersections if certain traffic conditions exist.
Safety concerns associated with multiway stops include pedestrians, bicyclists, and all road users expecting other
road users to stop. Muldway stop control is used where the volume of traffic on the intersecting roads is
approximately equal.
The restrictions on the use of STOP signs described in Section 213.05 also apply to multiway stop applications.
November 2003 Sect. 213.05 to 28.07
Page 2B-8
2003 Edition
Guidance:
The decision to install multiway stop control should be based on an engineering study.
The following criteria should be considered in the engineering study for a multiway STOP sign installation:
A. Where traffic control signals are justified, the multiway 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. A crash problem, as indicated b~ 5 or more reported crashes in a 12-month period that are susceptible to
correction by a multiway stop installation. Such crashes include right- 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 65 km/h or exceeds 40 mph,
the minimum vehicular volume warrants are 70 percent of the above values.
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:
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 reasonably
safely negotiate the intersection unless conflicting cross traffic is also required to stop; and
D. An intersection of two residential neighborhood collector (through) streets of similar design and
operating characteristics where muldway stop control would improve traffic operational characteristics of
the intersection.
Section 2B.08 YIELD Sign°M1-21
Standard:
The YEELD (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:
The YIELD sigri assigns right-of-way to traffic on certain approaches to an intersection. Vehicles controlled
by a YIELD sign need to slow down or stop when necessary to avoid interfering with conflicting traffic.
Section 2B.09 YIELD Sign Applications
Option:
YIELD signs may be used instead of STOP signs if engineering judgment indicates that one or more of the
following conditions exist:
A. When the ability to see all potentially conflicting traffic is sufficient to allow a road user traveling at the
posted speed, the 85th-percentile speed, or the statutory speed to pass through the intersection or to stop
in a reasonably safe manner.
B. If controlling a merge-type movement on the entering roadway where acceleration geometry and/or sight
distance is not adequate for merging traffic operation.
C. The second crossroad of a divided highway, where the median width at the intersection is 9 m (30 ft) or
greater. In this case, a STOP 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.
D. 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.
Standard:
A YIEELD (RI-2) sign shall be used to assign right-of-way at the entrance to a roundabout intersection.
Sect. 2B.07 to 2B.08 November 2003
MUTCD 2003 California Supplement Page 2B-1
CHAPTER 2B. REGULATORY SIGNS
Section 2B.01 Application of Regulatory Signs
The following is added to this section:
Standard:
Orders, ordinances and resolutions by local authorities which affect State highways shall be
approved by Department of Transportation.
Support:
Signs required for enforcement are normally placed by, and at the expense of, the authority establishing
the regulation.
Section 2B.02 Design of Regulatory Signs
The following is added to this section:
Support:
Sign design details are contained in FHWA's "Standard Highway Signs" book and Department of
Transportation's "Traffic Sign Specifications". See Section IA.l 1 for information regarding these
publications.
Table 213-101 shows a list of California Regulatory Signs.
Figure 213-101 shows California Regulatory Signs.
Section 2B.05 STOP Sign Applications
The following is added to this section:
Support:
A STOP (R1-1) sign is not a "cure-all" and is not a substitute for other traffic control devices. Often, the
1 need for a STOP (Rl-1) sign can be eliminated if the sight distance is increased by removing obstructions.
Through Highways
Option:
STOP (R1-1) signs may be installed either at or near the entrance to a State highway, except at signalized
intersections, or at any location so as to control traffic within an intersection. Refer to CVC 21352 and
21355. See Section IA.I l for information regarding this publication.
Support:
When STOP (RI-1) signs or traffic control signals have been erected at all entrances, a highway
constitutes a through highway. Refer to CVC 600.
Authority to place STOP (RI-1) signs facing State highway traffic is delegated to the Department of
Transportation's District Directors.
Option:
Local authorities may designate any highway under their jurisdiction as a through highway and install
STOP (R1-1) signs in a like manner. Refer to CVC 21354.
Standard:
No local authority shall erect or maintain any STOP (RI-1) sign or other traffic control device
requiring a stop, on any State highway, except by permission of the Department of Transportation.
Refer to CVC 21353.
Support:
The Department of Transportation will grant such permission only when an investigation indicates that
the STOP sign will benefit traffic. `
