BACKGROUND/REASONS FOR RECOMMENDATIONS
On January 17, 1995 the Board of Supervisors approved Development
Plan 3001-93 to establish an automotive oil/lube facility.
Subsequently, it was brought to the attention of the Public Works
Department, that the traffic counts presented to 'the Board were not
representative' of existing conditions. On January 31, 1995, the
Board voted to reconsider their decision because 1991 traffic
counts were represented as existing conditions and current traffic
counts for the Stone Valley/Danville Boulevard intersection were
not available to the Board at the time of their decision.
Furthermore, at the January 17, 1995 Board meeting, staff responded
to questions raised by the Board Members on alternative uses for
the site. Staff indicated that the configuration of the site would
limit the number of potential uses, with parking being the primary
concern.
Subsequently, a meeting occurred with Supervisor Bishop's staff,
the Public Works Department, the applicant and an AIA representa-
tive. Staff was requested to provide the following information:
1. Alternative uses for the site.
2. Project impact on the proposed trail along the creek.
3 . What is the acceptable level of service (LOS) at the intersec-
tion?
4. What is the current level of service at the intersection?
3
5. Why is the level of service in the Tri-Valley Transportation
Council (TVTC) model worse than the level of service calcula-
tions by County Staff?
1. Alternative Uses for the Site.
General Uses
The subject property is governed by the Retail-Business ordinance
(R-B) (see Exhibit 1) . Briefly, uses permitted in the R-B district
include the sale of retail goods, uses permitted in the single
family and two family districts, hotels and motels. Additionally,
the ordinance identifies a range of land uses permitted after the
issuance of a land use permit. Those uses include lumber, cabinet;
or sheet metal shop, animal hospital, dog kennel, auto garage,
building contractor's yard, other businesses where sales, demon-
strations, displays and services and other activities are conducted
in other than in an enclosed area, various types of manufacturing
and uses permitted in the single family and two family districts
after the granting of a land use permit.
Proposed Site
The subject property is a long east/west and relatively narrow
north/south parcel, in an irregular shape, with a relatively large
trapezoid at the east and smaller narrow panhandle to the west
extending along Stone Valley Road to Danville Boulevard. The site
is approximately 34,800 square feet in size with an useable area of
approximately 8, 000 ,square feet. The parcel is limited to 8, 000
square feet due to the location of San Ramon Creek, creek structure
setback, Flood Control maintenance easement, 5-foot dedication for
the widening of Stone Valley Road, and the -23-foot wide panhandle.
Development Requirements
The Retail-Business Ordinance requires a 10-foot setback from any
roadway, and has no provision for a side or rearyard setback.
Additionally, the Off-street Parking Ordinance requires one parking
space for every 250 square feet of retail space and one parking
space for every 200 square feet of office space, with the latter
being more restrictive. Furthermore, depending on the angle of
parking (e.g. , 450 , 600 , 900 , etc. ) the required dimensions for the
parking spaces and driveway/backup areas will vary (see Exhibit 2) .
Site Design
As discussed previously, the useable area of the subject property
is approximately 8, 000 square feet. Because the site is so
restricted, there are a limited number of uses that the site could
accommodate. In staff's opinion and review of the Ordinance Code,
the following uses may be viable for the site.
Use #1: Medical/Dental Office/Animal Hospital
■ Parking Requirements: 5 spaces for each doctor.
■ Limitations: The five required parking spaces
would restrict the use of the building to one doc-
tor.
■ Site Design: The orientation of the building is
not of concern. The required number of parking
spaces would limit the use of the bridling to one
doctor.
Use #2 : Publicly owned park/playground
■ Parking Requirements: The code does not expressly
state a minimum number of spaces, but 3 - 5 parking
spaces should be considered.
4
■ Limitations: The park would be located adjacent to
San Ramon Creek, I-680 on-ramp and Stone Valley
Road. The park would be limited to kids play area
(e.g. , play structures) . or passive recreation
(e.g. , trail head, picnic benches, barbecues) .
Safety and noise impacts would be a concern with
this use.
■ Site Desicrn: Access to the site could be from the
western portion of the panhandle, with a one way
direction, exiting at the eastern most portion of
the .panhandle. Approximately three parking spaces
could be accommodated along the northern boundary
of the panhandle, while providing a 16-foot drive-
way. The park would then be accommodated in the
rectangular portion of the site, east of the pan-
handle.
Use #3 : Office:
■ Parking Requirements: - One space every 200 square
feet.
■ Limitations: The configuration of the site would
permit a building ranging in size from 800 - 1,200
square feet in size, with a requirement of four to
five parking spaces.
■ Site Design: A building could be oriented in an
east/west or a north/south direction, with access
provided in a similar manner to the proposed pro-
ject. To accommodate a building larger than 1, 000
square feet parking would be necessary along the
panhandle.
Use #4 Retail:
■ Parking Requirements: - One. space every 250 square
feet.
■ Limitations: Similar to office use.
■ Site Design: Similar to office use.
Use #5 Building Contractor's Yard:
■ Parking Requirements: - One parking space for each
two employees.
■ Limitations: No fixed structures, with the excep-
tion of a small office or caretaker trailer.
■ Site Design: A solid six-foot fence would be
required along the perimeter of the site. The
majority of- the site would be left open to allow
the contractor to maximize the material storage
area. Materials should not exceed a stacked height
of six feet.
2. Project Zmpact on the Proposed Trail along the Creek.
On January 3.0, 1995, staff field reviewed other recent projects on
San Ramon Creek and neighboring properties to determine the
feasibility of installing a trail along the top of the creek bank.
From the field review, it appeared it would be difficult to install
a trail on the west side of San Ramon Creek in the vicinity of this
project. The Alamo Park and Recreation District R7A, is currently
reviewing the "San Ramon Creek Greenbelt and Parkway Study" that
identifies a trail on either side of San Ramon Creek. In other
words, the study does not identify a preference for the east or
5
west side of the creek. A recent project upstream of the automotive
oil/lube facility project was required to work with R7A to develop
a trail easement. The applicant has indicated his support to work
with R7A to identify :a trail on the project site. This requirement
is reflected in Condition of Approval #14 .
t
3. What lis the acceptable level of service (LOS) at the intersec-
tion?
Background•
i
There are two things to consider when determining what is the
appropriate level of service for an intersection;,
a. !What is the type of land use in the area of the intersec-
tion, as indicated in table 4-1 and Figure 4-2 of the
;general plan?
b. !Is the intersection located on a basic route or a route
of regional significance?
Table 4-1 of the general plan relates the level of service
performance standard to the intensity of the surrounding land
use, ' For example, an intersection in a rural area has a LOS
C ds� its performance standard, while a central business
distr�ic:t has a LOS E as its performance standard. As the
inteinsi.ty of development increases from rural to urban, the
performance standard is adjusted to allow for more congestion.
Figure 4-2 in the general plan is a map of the county showing
which areas are . rural, suburban, urban or central business
district. By relating the land use shown on Figure 4-2 with
the performance standards on Table 4-1, the appropriate level
of service can be determined.
Figure 4-2 in the general plan shows this intersection is in
an urban area. Intersections in urban areas are allowed to
operate up to LOS D, with a maximum volume to capacity ratio
of .89, and still satisfy Measure C. The intersection could
even exceed the level of service standard provided the County
has a project in the Capital Improvement . program that will
improve the intersection within five years. The above level
of service performance standards would apply for basic routes
but not. for routes of regional significance. If an intersec-
tion is located on a'-route of regional significance, then the
LOS performance standards in Table 4-1 do not apply. The
performance standard for routes of regional significance will
be designated by the Action Plan for that regional route.
Danville Boulevard is designated as a route of regional
significance by the Contra Costa Transportation Authority
(CCTA) . The draft action Plan for the TVTC region calls for
a volume to capacity ratio of 0.90 or better for the year
2010. A volume to capacity ratio of '.90 is technically LOS E,
since LOS E ranges from .90 to .99. However , since .89 and
.90 are on the borderline between LOS D and E, the practical
maximum level of service for this intersection is LOS D.
Conclusion .
If the action plan is approved as currently drafted, the
performance standard for this intersection would be a volume
to capacity ratio of .90 which is between LOS D and LOS E.
4. What is the current level of service at the intersection?
Background
Public Works staff took turning movement counts at the
intersection on February 7, 1995. Turning movement counts
were also taken on February 15, 1995 to allow the community an
opportunity to " observe our traffic counting procedures.
Turning movement counts are the detailed data needed to
calculate the level of service at a signalized intersection.
The process entails engineering technicians visiting the
intersection during the a.m. peak commute period and the p.m.
peak commute period. The technicians count the number of cars
making each turning movement. For example, in the eastbound
direction on Stone Valley Road, the cars turning right would
be counted as well ' as the cars going through and the cars
turning left. This would be done for westbound Stone Valley
Road in addition to north and southbound Danville Boulevard
for a total of twelve different movements. In addition to
counting the turning movements, we put automated traffic
counters on each approach to the intersection. This consisted
of putting rubber tubes and counters across Stone Valley Road
and Danville Boulevard in each direction before the intersec-
tion. The counters gave us total numbers of vehicles in each
direction which enabled us to double check the data from the
turning movement counts in the intersection. We also timed
the delay for each turning movement in the intersection. This
entailed an Engineering Technician repeatedly driving through
the intersection with a stop watch. The delay is the time the
vehicle was actually stopped while going through the intersec-
tion making any one of the twelve movements. The delay time
data also helps to validate the level of service calculations.
After collecting the turning movement counts, staff input the
data into a computer program developed by the Contra Costa
Transportation Authority (CCTA) for determining the level of
service at a signalized intersection. Included in this Board
Order as Exhibit 3, is the computer printout showing the
traffic: turning movement data and the level of service for
February 15, 1995, in addition to previous count dates. The
results are summarized in the table below.
LEVEL OF SERVICE SUMMARY TABLE

V/C = Volume• to capacity ratio
LOS A B C D E F
V/C less .60-.69 .70-.79 .80-.89 .90-.99 1.00+
than .59
In reviewing the above summary table it can be .concluded that
the level of service in the morning commute is B to C and in
the afternoon commute is C to D. Some Alamo residents who
drive through this intersection may perceive the intersection
as operating at a more congested level. This may be due to
unbalanced delays experienced at the intersection. In
reviewing the delay time data, it appears that some turning
movements are experiencing a much longer delay than other
movements. This is partly due to the relatively long cycle
length of the signal. Public Works staff will experiment with
the signal timing so that the delay is more evenly distribut-
ed. This will reduce the disproportionately long delays now
occurring at a couple of turning movements, which dives the
perception that the overall intersection is operating worse
than it is.
This intersection is currently operating within the perfor-
mance standards required by Measure C. There are over 2500
movements or trips through the intersection during the morning
and afternoon peak periods. The proposed project will add 9
trips in and out for a total of 18 trips through the intersec-
tion, assuming each customer goes through the intersection
twice. Adding 18 more tris through the intersection is less
than a 1% increase and will not be noticeable. The added
trips from the proposed project would not change the level of
service at the intersection.
It should be noted that the level of service on any particular
day can be influenced by many factors, such as the weather,
the day of the week, the time of year, special days (Holidays,
etc. ) , accidents or road work on I-680, sales at the retail
stores in the area, and capacity improvements to I-680.

Conclusion
a. The current level of service in the morning . commute
period is LOS B or LOS C, and in the afternoon commute
period is LOS C or LOS D.
b. Public Works will also adjust the signal timing to reduce
the disproportionately long delay experienced in some of
the turning movements.
c. This intersection is currently operating within the
Measure C guidelines. The traffic added by this project
will not significantly change the current traffic service
levels.
5. Why is the level of service in the Tri-Valley Transportation
Council (TVTC) model worse than the level of service calculat-
ed by County staff?
Background
Public Works staff obtained a copy of the level of service
calculations for the intersection from Barton Aschman, the
consultants preparing the Tri-Valley Transportation Council
model. Their calculations indicated the level of service for
the a.m.. peak hour was LOS C and for the p.m. peak hour was
LOS E. A copy is attached for reference. Their traffic
counts were taken in December of 1989. In .reviewing their
computer printout, County staff discovered some errors in the
data input for the configuration of the intersection.
When traffic count data is entered into the computer program
for each turning movement, the programmer must also assign a
descriptor that tells the computer the lane configuration of
that turning movement. Based on the lane configuration
descriptor, the computer will assign a capacity to that
turning movement. For example, a right turn lane controlled
by a signal, where a car must stop before turning right, has
less capacity than a free right turn that is not controlled by
a signal. Each of these two right turn lane configurations
has a different descriptor. The descriptor for the right turn
lane controlled by a signal tells the computer there is less
capacity in that turning movement than a turning movement for
a free right turn not controlled by a signal. The descriptors
are similar to settings on a lawn sprinkler, where different
settings let different volumes of water emanate from the
sprinkler. The descriptors tell the computer the relative
capacity for the various lane configurations.
In reviewing the computer printout from Barton Aschman it
turns out they assigned lower capacity descriptors on a couple
of the turning movements. For example, Stone Valley Road
turning right onto northbound Danville Boulevard was assigned
a descriptor for a right turn lane controlled by a traffic
signal. County staff, however, assigned a descriptor that
better reflects the configuration of the intersection, which
is a right turn lane not under the control of a signal.
County staff then ran the computer program using the traffic
turning counts from Barton Aschman with the lane configuration
assignments by County staff. The level of service turns out
to be LOS D in the afternoon commute, rather than LOS E as
calculated by Barton Aschman. When using the correct descript-
ors, the TVTC level of service at the intersection is in the
same range as that calculated by County staff.
Conclusion
The level of service calculations performed for the TVTC
transportation plan incorrectly described the lane configura-
tion while inputing data into the computer program. The
result is the calculated LOS is off by one level of service.
When County staff ran the TVTC data in the computer using the
correct lane configurations, the results were similar to the
results of other LOS calculations by County staff.
Alternatives
There are several alternatives the Board could consider to
address the traffic impacts from this development. The
primary impact is the conflict of traffic from northbound
Danville Boulevard turning right (to the east) and southbound
7
Danville Boulevard turning left (to the east) . The conflict
occurs when the traffic from these two turning movements try
to access the project site and cross each other. The staff
recommendation in the conditions of approval is to install
traffic bars along the traffic lane line to separate the two
traffic movements. This would be a temporary measure until
the intersection improvements are constructed. An alternative
would be to require these interim improvements and a cash
contribution toward the ultimate intersection improvements
above and beyond the Area of Benefit fee. The nexus would be
the increased turning movements at the intersection created by
the project. Another alternative would be to require the
construction of the ultimate curb return and the removal of
the small island and relocation of the traffic signal. This
would eliminate the free right turn movement at the southeast
corner and the conflict between the .two turning movements.
The applicant would be reimbursed from Area of Benefit funds
for some of these improvements. While this would eliminate
the conflict between the turning movements, it would increase
the congestion level at the - intersection. The vehicles
turning right would have to stop or a red light before
turning,, which would result in more vehicles queuing up at the
intersection and a longer delay time. Although the level of
service performance standard would not be violated, some
motorists may notice an increased delay. .The AOB fee is based
on the number of p.m. peak hour trips a development generates
and is determined by the square footage of the structure
unless the actual peak hour trip generation is known. For
this developmentthe AOB fee based on the square footage of
the structure would be $6600. However, we also know the p.m.
peak hour trips generated by this development. , Based upon the
peak hour trips, the AOB fee would be $39, 618. The Board may
consider a combination of option 1 and 2, under the recommen-
dation section of this Board Order, by requiring the mitiga-
tion measure in option 1 and payment of the higher AOB fee.
