DESCRIPTION: At the July 7th meeting, the City Council adopted a resolution
authorizing enforcement of the California Vehicle Code (CVe) regulation on streets within the Hansen
Hill, Phase I, development as these streets had not yet been accepted as City streets. During the public
hearing, some residents of the development expressed dissatisfaction with action taken to alleviate
speeding and other traffic concerns, particularly on Bay Laurel Street. The City Council directed Staff
to prepare a report regarding the studies that have been conducted and action taken. Following is a brief
history.
In response to the homeowners' concerns regarding traffic on Bay Laurel Street, including speeding,
noise, traffic volume, and parking restrictions, the Public Works Department and its consultant, TJKM,
conducted a series of traffic studies. When homeowners' concerns were first received, the Hansen Hill
project was still under construction and was not part ofthe City's jurisdiction; therefore, the developer
was responsible for safety and traffic issues; however, Staff did organize meetings (day and evening) and
worked with the homeowners, developer and Valley Christian Center (VCC) to develop solutions and
mitigations in an attempt to satisfy the involved parties. The Dublin Police Department, Fire Department,

g: agenmisclbaylarl2.doc
Warmington Homes, and Valley Christian School were very cooperative, attended all meetings and .
assisted Staff in working through residents' traffic concerns.
Speed counters were installed at four locations along Bay Laurel Street on November 4th and 5th, 1997
(prior to the reopening of Inspiration Drive) and on December 9th and 10th, 1997 (after the opening of
Inspiration Drive). The results of the speed survey and volume count are shown below in TABLE A.
A few members of the Homeowner's Association had some questions and concerns with the results and
requested an evening meeting, subsequently held at Valley ehristian Center on December 18, 1997.
Residents at that meeting requested that additional speed and volume counts be conducted on Bay Laurel
Street on or after Monday, January 5, 1998 (the first day back to school). At the same meeting, Valley
Christian School Staff indicated they would be responsible for educating parents to use only Inspiration
Drive from Dublin Blvd. for student pick-up and drop-off.
Based on residents' requests, the study was conducted while Valley Christian School was fully
operational. Speed and volume counters were installed in locations requested by residents with counter
hoses extending from curb to curb to count all approaching traffic. The study shows that the 85th
percentile speeds range from 25 mph to 31 mph along Bay Laurel. The data indicates that the average
daily traffic on Bay Laurel Street ranges from approximately 425 vehicles near the top ofthe hilI to
approximately 600 vehicles toward the bottom of the hill. These volumes and speeds are typical and
reasonable for residential collector streets. The reason the bottom of the hill has more traffic volume is
that there are about 16 houses between Inspiration Circle and Silvergate Drive (residential homes typically.
generate 10 trips per house per day). Following are the results of the volume and speed study.

Speed limits for most residential streets should be established preferably at or near the 85th percentile
speed, which is defined as that speed at or below which 85 percent of the traffic is moving. The 85th
percentile is often referred to as critical speed. These volumes and speeds are reasonable for a residential
collector street with a 25 mph speed limit.
.
Packages containing the results of the study were hand delivered to all of the residents on Bay Laurel .
Street on February 23, 1998 (Exhibit 1). As part of the package, Staff requested that residents respond to
the study. Staff did receive comments on April 6,1998 (Exhibit 4). The results were also presented to the
residents by Mr~ Andrew Walker, Homeowner Association ehairman, at their Homeowner's meeting in
April 1998. According to Mr. Walker, the Hansen Hill residents were satisfied with the results, except for
three homeowners. The Homeowners' Association also expressed their appreciation to Valley ehristian' s
Pastor for sending letters to the parents of the students attending the school asking them not to use Bay
Laurel Street as an access to the school.
Based on requests from the Homeowners' Association, City Staff also agreed to and has completed, or
had the developer complete, the following traffic revisions:

The Dublin Police Department is proposing to target the Bay Laurel Street area for stepped-up
enforcement during the first few weeks of school in September. This is being done, along with higher
enforcement around the other schools, to remind people ofthe need for safety when the schools are in
session.
The following mitigations were also discussed; however, they were rejected, either by residents, or by
Police and Fire Departments as they would interfere with the delivery of emergency services in a timely
manner (see Exhibit 3):
Construct permanent barricades on Inspiration Drive at Inspiration Circle and install signs
indicating for emergency access only.
elose the portion of Inspiration Circle between Inspiration Drive and Bay Laurel Street.
Install NO LEFT TURN signs for traffic exiting vce and install a raised center median on
Inspiration Drive.
Install NO LEFT TURN signs for traffic exiting VCC (no median), with time restrictions.
Install all-way STOP signs at Bay Laurel StreetlBay Laurel Court and at Bay Laurel Street!
Buckeye Court (requested by a few residents, but rejected by the majority).
Establish speed limit (20 - 25 mph) and install signs to slow down speeders.

7. Install entry signage that states: "This is a residential community, please drive with caution, .
children at play, etc.
8. Install signs stating NOT A THROUGH STREET or NO THROUGH TRAFFIC ON BAY
LAUREL, USE....
9. Install NO LEFT TURN signs on westbound Bay Laurel Street at Inspiration Circle and on
southbound Inspiration Circle at Inspiration Drive.
10. Install a NO RIGHT TURN sign on Inspiration Drive at Inspiration eircle.
11. Install speed humps on Bay Laurel Street.
12. Install traffic circles at Bay Laurel StreetlBuckeye eourt and Bay Laurel StreetlBay Laurel Court.
It should be noted that there is considerable traffic to and from the construction portions of the
development which will eventually disappear, but new traffic from the 108 units in Phase II Hansen Hills
plus 17 units on the Gleason property will increase the traffic over the existing traffic.
In analyzing the traffic near the top of Bay Laurel Street, the 425 vehicles per day are primarily from the
on going phase II subdivision traffic and Valley Christen School traffic.
On January 6th, vehicle counts were made on either side of the Valley Christian Centers upper driveways.
Twenty four hour traffic counts to and from Dublin Blvd. were 1965. Two way traffic to and from the
north (which includes construction traffic) was 230 for the same 24 hour period. This would indicate that
only about 10% of the school traffic is using Bay Laurel Street compared to Dublin Blvd. to get to and
from the Valley Christian Center. .
Based on the traffic studies, Staff believes that no further action is warranted and the existing striping and
stop signs are adequate.
TIlls report is presented for the City Council's information and review. Staff recommends that Council
provide direction to Staff regarding additional action or study, if deemed necessary.

SUBJECT:
Bay Laurel Traffic Issue
Dear Resident:
In response to comments received from Bay Laurel residents on the last evening
meeting dated Thursday, December 18, 1997, regarding speeding and vehicle volumes,
the City's pUblic Works Department and its consultant, TJKM, has conducted a series of
traffic studies including vehicle volume and speed.
Based on resident's requests the study took place when school, Valley Christian center,
was fully operating (Please see the attached TJKM memo regarding the results of the
study). The result of the study shows the 85th percentile speeds range from 25 mph to 31
mph along Bay Laurel. The data indicates that the average daily traffic on Bay Laurel .
ranges from approximately 425 vehicles at the top of the hill to approximately 600
vehicle at the bottom of the hill. These volumes and speed are typical and reasonable for
a residential street. The City of Dublin Public works, based on the recent traffic study,
recommends that the existing striping and stop signs should be adequate.
If you have any comments or objections regarding this matter, please call Saied Aminian
at 833-6630. we will be glad to set another meeting to discuss the result of the study or
this matter can be taken to the City council for further evaluations. Please respond by
March 5th, 1998.
Thank you for your understanding and patient. we appreciate your input regarding this
issue. If you have any questions, please feel free to call me.
Sincerely,

Summary of Speed and Volume Counts on Bay Laurel Street and
Turn Counts along Inspirations Drive and Silvergate Drive
. To:
From:
Background
On December 18, 1997, a meeting was held at Valley Christian Center (VCC) to discuss
Hansen Hill traffic issues. Residents at that meeting requested that additional speed
and volume counts be conducted on Bay Laurel Street on Monday, January 5,1998 (the
first day of school after Christmas break). This memo sUIDIDarizes the data collected on
Bay Laurel, as well as the turn counts conducted on Inspiration Drive and on Silvergate
Drive.
.
Speed and Volume Counts on Bay Laurel
Counters were installed at four locations along Bay Laurel on November 4-5, 1997,
while barricades were placed across Inspiration Drive at Inspiration Circle. Counters
were installed at the same four locations along Bay Laurel on December 9-10, 1997,
after the barricades were removed from Inspiration Drive at Inspiration Circle. In
response to the residents, counters were installed at the same four locations and two
additionallocations along Bay Laurel on January 3-7, 1998. Table 1 summaries the
volume and speed data collected on these dates.
The data indicates that the average daiJy traffic on Bay Laurel ranges from
approximately 425 vehicles at the top oftthe hill to approximately 600 vehicles at the
bottom of the hill. The 85th percentile sp~eds range from 25 mph to 31 mph along Bay
Laurel. These volumes and speeds are reasonable for a residential street, and may be
even relatively low compared to other residential streets in Dublin. For example, the
85th percentile speeds on West Vomac Road (a relatively steep residential street) range
from 28 mph to 35 mph.
Use of Bay Laurel to Access Valley Christian Center
.
Turn counts were conducted at the three driveways for Valley Christian Center along
Inspiration Drive on Monday, January 5, 1998 from 7:00 a.m. to 9:00 a.m. and on
Tuesday, January 27,1998 from 2:15 p.m. to 3:30 p.m. The morning count revealed
that 100 vehicles between 7:00 and 9:00 approached Inspiration Drive from the north,
and most likely from southbound Silvergate Drive via Bay Laurel. To confirm this
assumption, turn counts were conducted at SilvergatelBay Laurel and
Silvergate/Dublin Boulevard on V\7ednesday, January 7, 1998 from 7:00 a.m. to 9:00
4134 Hacienda Drive. Suite 101, PJeasantOn. California 94588+17:21, (510) 463-06 J 1, F;>.x (5] 0) 463-3690

tj rf i1
a.m. During this two-hour period, 99 vehicles from southbolUld Silvergate turned right .
onto Bay Laurel, while 129 vehicles from southbound Silvergate turned right onto
Dublin Boulevard. The COlUlt at Silvergate/Bay Laurel confirms that during the
morning approximately 100 vehicles (including residents on Bay Laurel) use Bay Laurel
to access Valley Christian Center.
Mr. Mehran Sepehri

Impact of Left Turn Prohibition at VCC Driveways
Between 7:00 a.m. and 9:00 a.m. on January 5, 1998, the left turn volume exiting vce .
were 18, 11, and 2 for the northem, center, and southern driveways, respectively.
Similarly, between 2:15 p.m. and 3:30 p.m. on January 27, 1998, the left turn volume
exiting vec were 16, 8, and 5 for the three driveways. These counts indicate that a
left-turn prohibition at one, two, or even all three of the vee driveways would do little
to reduce traffic volumes on Bay Laurel. Such a prohibition will cause delays for vec
students/parents who live on Bay Laurel and would probably lead to southbound to
northbound V-turns on Inspiration Drive.

Hansen Hill Ranch Traffic Concerns
Following is action taken to date on concerns expressed by residents of Hansen Hill Ranch
development.
Ten residents/homeowners attended the Traffic Safety Committee meeting of October 21, 1997.
This meeting was also attended by two representatives of Warmington Homes and two
representatives of Valley Christian Church/Schools, as well as regular TSC members.
Attached are minutes of that meeting, along with an attendance list. Following are concerns
and proposals that were expressed, and Staff's response or action taken to date:
.
School Traffic Usinq Bay Laurel Street:
The homeowners would prefer that the access to the school via Bay Laurel remain closed to
traffic, although it could be available for emergency access only. If this is not possible, they
would like to see "No Left Turn" traffic control at the Valley Christian driveways and possibly a
median on Inspiration Drive in order to force traffic to at least leave the area via Inspiration
Drive and Dublin Boulevard rather than returning on Bay Laurel.
The second access for the schoo/ was a Condition of Approva/ and is needed for emergency
purposes. Closing the access completely would delay response time for emergency vehicles
and is therefore not an option. Other considerations include the fact that the homeowners
themselves would have to live with the same restrictions. There are a number of issues
involved, including whether median breaks would be provided for left turns into the driveways,
whether V-turns would then become a problem, and whether the restrictions could or should be
time-limited so that only the peak traffic periods are affected. These issues are still under
discussion. If such restrictions are implemented, Valley Christian would need to make
modifications to their parking lot traffic flow.
Speeding: The homeowners indicated that traffic speeds on Bay Laurel and that they have a
problem getting out of their driveways safely. Some residents asked for stop sign control at the
Bay Laurelllnspiration intersection, Bay Laurel/Buckeye Ct. intersection, and Bay L;aurellBay .
Laurel Ct. intersection.

) .
Speed studieS"Bnd stop sign studies were performed under the present condition with the road
closure. The speed surveys were taken by mechanical means (not by radar). 85th percentile
speeds ranged from 29 mph to 31 mph depending on location. This is a residential street and
the 25 mph prima facie speed limit applies. Stop sign volume warrants were not met at the two
court locations, and stop signs are not recommended as a means of speed control. It was
agreed that the Bay Laurel/Inspiration intersection. would be a reasonable all-way stop. It was
also noted that speeding is an enforcement issue.
Noise:
The homeowners would like to reduce noise from vehicles.
.The City cannot do anything about vehicle noise. If stop signs are installed, the noise will be
increased at the stop sign locations.
No Parking Areas: One homeowner had an issue with No Parking Zones in front of their
houses.
It was agreed that the No Parking Zones could be removed in front of her house..
Crosswalks Requested: . Crosswalks were requested crossing Bay Laurel at Silvergate and
crossing Silvergate at Hansen Drive.
The Bay Laurel crosswalk is part of the improvement plans and will be painted as soon as the
street has been slurry sealed. Staff agreed to provide crosswalks on Silvergate Drive at
Hansen Drive.
Lane Modification on Dublin Boulevard at Hansen: It was requested that the eastbound right
turn only lane on Dublin Boulevard at Hansen be available for through traffic.
Staff agreed to change this lane to a through-and-right.
Centerline and Edge Lines on Bay Laurel: This was suggested by Staff as a device which
may slow traffic by making the roadway feel narrower. The homeowners indicated they were
interested in trying this.
Staff agreed to have the striping done.
The striping modifications noted above will be included in the next work order for the City's
striping contractor, and some will be done by the developer. In addition, it was suggested to
the homeowners' association representative that further traffic studies should be performed with
the barricades removed in order to obtain more realistic information regarding traffic volume
and speeds.
The homeowners' association traffic committee will be advised of this within the next couple of
days. There is a meeting of the entire homeowners' association on November 19th, and they
will be advised at that time of the above actions. Tne members are invited to attend the next
Traffic Safety Committee meeting, which is tentatively scheduled for December 2nd.

Meeting Date: December 18, 1997, 6:00 p.rn.
AGENDA and OUTLINE
Introduction
Homeowners from Hansen Hill have expressed a numqer of concerns regarding traffic on Bay
Laurel Street, includiI1g speeding, noise, volumes, and parking restrictions. Possible mitigation to
these concerns were expressed in a memo from the homeowners dated October 17, 1997, and
discussed at a meeting held at City Hall on October 21, 1997. The purpose of tonight's meeting
is to discuss the potential impact of various mitigation measures, as weIl as to present an update
of what measures been implemented and will be implemented.
Speed counters were installed at four locations along Bay Laurel Street, two in the downhill
(eastbound) direction and two in the uphill (westbound) direction. Tbe'counters were installed on
November 4-5 (prior to the opening ofInspiration Drive) and on December 9-10 (after the
opening ofInspiration Drive). Tbe results of the counts indicate that the traffic volumes ranged
from 180 - 294 vehicles pei day (vpd) in November to 185 - 277 vpd in December. Volumes on
typical residential streets can be as high as 1,500 vpd. Meanwhile, the 85th percentile speed
ranged from 25 - 31 mph in November and 26 - 31 mph in December. 85th percentile speeds on
typical residential streets can be as high as 36 mph.
Proposed Miti2ation Measures .
1. Construct permanent barricades on Inspiration Drive at Inspiration Circle and sign for
emergency access only.
· Would eliminate second access for Hansen Hill that was required by the City's
Conditions of Approval for the development
· Would force all existing Bay Laurel traffic to exit onto Silvergate Drive, which was a
concern raised by homeowners along Silvergate prior to the development of Hansen Hill
· Would force all future traffic on Inspiration Circle to Bay Laurel Street and Silvergate
· Would eliminate second access. for Valley Christian Center (VCC) that was required by
the City's Conditions of Approval for Valley Christian School
· Would force all VCC traffic (even those from Hansen Hill and future development in the
area) onto Inspiration Drive via Dublin Boulevard
· Would increase emergency response time
· Would require a turnaround area for normal traffic and emergency vehicles
2. Close small portion of Inspiration Circle between Inspiration Drive and Bay Laurel Street
. Would not be feasible until entire stretch ofInspiration Circle is built
· Would increase traffic volume and travel time in each direction between Inspiration
Drive, Inspiration Circle, and Bay Laurel St.
· Would increase emergency response time
3. Install NO LEFT TURN signs for traffic exiting VCC & a raised center median on Inspiration Dr.
· Would force all traffic exiting VCC to turn right onto Inspiration Drive
· Would increase travel time for Hansen Hill residents from VCC to Hansen Hill Development .
and other future development in the area
· Breaks in the median would be needed to allow for left turtle:: ;ntn vrr
[r:~~S~T
L~
7 ,,1 )~
.
. Median design would need to balance between discouraging left rums from vec, yet allowing
for left IDrns in case of emergency
. Traffic exiting vce may turn right, then attempt a U-turn at median breaks or at Dublin Blvd.
. NO U-TURN on Inspiration Drive would be difficult to enforce
. Incoming VCC traffic could still use Bay Laurel
. Major costs would be associated with the median & funding source would be needed
4. Install NO LEFT TURN (e.g., 7 am-9am. and 3pm-5pm) signs for traffic exiting VCC (no median)
. Would force all traffic exiting VCC to turn right onto InspiratIon Drive
. Would increase travel time for Hansen Hill residents from vee to Hansen Hill Development
and other future development in the area
. Traffic exiting VCC may turn right, then attempt a U.turn between driveways
. NO LEFT TURN from VCC & NO U-TURN on Inspiration Dr. would be difficult to enforce
. Incoming VCC traffic could still use Bay Laurel
. Any restrictions to VCC traffic would require the support ofVCC leadership and drivers
5. Install all-way STOP signs at Inspiration Circle/Inspiration Dr. & at Inspiration Circle/Bay Laurel
. STOP signs have been installed on all approaches at Inspiration Circle/Inspiration Drive
. STOP sign has been installed for westbound Bay Laurel at Inspiration Circle. Wormington
will have STOP signs installed on both approaches on Inspiration Circle
. Noise and pollution will increase due to braking and accelerating of vehicles at STOP signs
.
6. Install all-way STOP signs at Bay Laurel Street/Bay Laurel Court and Bay Laurel St./Buckeye Ct.
. "Unwarranted" STOP signs may result in noncompliance, increased speeding, accidents, and
"false sense of security"
. Noise and pollution will increase due to braking and accelerating of vehicles at STOP signs
. STOP signs may not increase delay enough to make route less attractive than Dublin Blvd.
7. Establish speed limit (20 - 25 mph) and install signs to slow speeders
. California Vehicle Code indicates that speed limit on local residential streets should be
25mph. Lower speed limits are allowed at alleys, railroad grade crossings, and intersections
with sight restrictions.
. City prefers not to instaU25 mph signs on residential streets, which may result in additional
installations in other neighborhoods and ultimately more cost to the City
8. Remove or minimize no parking areas.
. City staff has responded to the one request and determmed that No Parking could be removed
. City staff will investigate any other requests made at this time
9. Install entry signage that state: This is a residential community, please drive with caution, children
at play, etc.
. May give residents a "false sense of security"
. Creates a liability issue for the City by implying that it is o.k. for children to play in the street
. Not approved traffic control devices
.
10. Install "NOT A THROUGH STREET" sign or "No Through Traffic on Bay Laurel Use..."
. NOT A THROUGH STREET sign is intended for dead-end streets

Mehran Sepehri
Senior Civil Engineer
City of Dublin
Dear Mr. Sepehri,
I am writing in response to your letter of February 23. 1998, concerning Bay Laurel
Traffic Issue in the Hansen Hills Development. I am sorry it has taken until now for me to
respond, but I did not receive a copy of the letter until the first week in March, and I have
since been out of town. However, I feel it is very important that you know how I, and my
neighbors, feel about this report
First of all. we still do not believe that these are any where near accurate counts.
According to this report there were a total of 20 cars exiting Valley Christian and turning
left onto Inspiration, then Bay Laurel This is completely ridiculous. I want you to come
and stand in my driveway and count the cars that come down from Valley Christian, and
not stopping at the stop signs. by the way. In addition, they are saying that 425 cars were
counted at the top of the hill, and 600 at the bottom This would mean that all the
households in between resulted in 175 trips. There were approximately 8 houses beyond
where the counter was placed at the top of hill How many trips could these 8 households
possibly make to add up to 425? Jill in all. these numbers do not .add up nor make any
sense.
.
Even putting this issue aside. the problem of speeding and ignoring stop signs is still
rampant. You can come look at our street and see all the skid marks at the turns where
people are having to slam on their brakes to make the turn. In addition, the striping has
not stopped them from crossing it to go around cars trying to back out, or turn into their
driveways. We now have a new problem with the sports programs beginning. The
teenage drivers are attending after school activities at all times of the evening. and using
Bay Laurel as a raceway for getting to and from the school In addition, on weekend
nights. we hear them racing on Inspiration Drive. making the turn onto Bay Laurel, and
speeding down Bay Laurel I really believe that. as a neighborhood, we should not have
to endure these traffic problems from this school I think it is time for us to do as
communities in Danville have done, and take back our neighborhood.

Numerous times I have posed the question "why is that cut through to Inspiration Drive
required". As of yet I still have not had a response that makes any sense. As for
"emergency access" for the circle that is yet to be built, I don't see the reasoning. I have
driven the street that goes through the Kaufman and Broad California townhomes and it is
structured exactly like Bay LaureL It is one continous circle, and there is no "cut
through" for emergency vehicles there. There is one street in, and one street out, exactly
as Bay Laurel and Inspiration Drive.
Quite frankly, I resent the statements "are typical of a residential screet" and comparing
Bay Laurel to West Vomac, or any other street. There are no two streets exactly the same
in regards to steepness, curves, location,' number of residents, and surrounding conditions.
Just lY'".,eause people speed on other streets, and are accepted, that does not mean we
should have to accept it on our street. We are all taxpaying residents, and the majority of
people abusing our street and neighborhood, are not Dublin residents. Like it or not,
Silvergate is a main, north to south artery, that was built to withstand traffic. Bay Laurel
is a narrow, winding, steep road that was not built to handle 150-200 cars in a 2 hour time
period, and allow the residents to feel safe.
.
I would appreciate hearing your thoughts on this matter, and hope the city will not
consider this a closed issue. As long as we have to endure these thoughtless, dangerous
conditions, I can assure you, we will not consider it closed.
Sincerely,
6/l~

Re: Traffic Enforcement Bay Laurel St.
Chief Thuman,
As you are probably aware, our association has been meeting with city staff since about
October 1997 regarding traffic safety issues along Bay Laurel St. Until recently your
department was unable to effectively intervene due to restrictions outside of your control.
Fourtunately, in July 1998 the city saw fit to authorize immediate traffic enforcement of
streets with in the Hansen Hill development.
I am writing to you to inform you and your staff of an area within the city where the
most frequent and blatant traffic violations are occurring. I am well aware that your staff
is responsible for the safety and protection of the city at large, and follows a certain
priority in fullfiIling its duties. But nevertheless, I would think that the frequent and
blatant violations in the way of failures to stop, and rolling stops that are occuring at the .
intersection of Bay Laurel and Inspiration Cir. should warrant a higher ranking and level
of enforcement than that which is curently in effect.
I must say that I have noticed a police presence within our community, but I beleive the
area indicated above could be enforced more effectively, and violations would be
discouraged if officers were assigned to devote more time in this area, especially during
ours of peak usage, 7:30am -8:30 am and 3:00pm -4:00pm. I must add, that the
mentioned violations are occuring at this intersection all times of day, and not just at the
times of peak usage. I would even venture to say that the revenue generated from
enforcing traffic laws at this location would justify the apportionment of your staffs time.
In closing I would like to add that speeding is also an issue along Bay Laurel, and the
violations which occur at the intesection mentioned contributes to the speeding problem.
Thank you very much!
