PLANNING AND TRANSPORTATION COMISSIONRECOMMENDATION TO THE CITY COUNCIL TO ADOPT ARESOLUTION APPROVING NO PARKING ZONES ONARASTRADERO ROAD AT TERMAN DRIVE
REPORT IN BRIEF
A significant increase in traffic turning left from Arastradero Road onto Terman Drive is
anticipated with the opening of the Terman Middle School in September 2003. The Terman
Middle School Draft Environmental Impact Report identifies creation of left-turn pockets
and left-turn signal phases as a traffic mitigation. At present, delay and traffic back-up occur
on Arastradero due to left-turning traffic and there is an accident history of collisions
between left-turners and opposing through traffic. Present and anticipated traffic congestion
and safety problems can be addressed through implementation of left-turn pockets and left-
turn signal phases at the intersection of Arastradero and Donald!Terman.
Creation of left-turn pocket requires at least 9.5 feet of pavement width. The Comprehensive
Plan, however, discourages increases in curb-to-curb pavement width while at the same time
encourages creation or maintenance of cycling facilities such as the existing bicycle lanes on
Arastradero which serve schools, libraries, and other community activity centers. Working
within these constraints requires re-allocation of pavement width in the vicinity of the
Arastradero and Donald/Terman intersection, which is now devoted to parking, to new left-
turn pockets.
Staff proposes creation of left-turning lanes of minimum acceptable width and length while
retaining minimum acceptabl6 bicycle lane width. Nevertheless, this will require removal of
approximately eighteen 24-hour parking spaces, which would be eliminated along the fronts
and sides of residences on the north side of Arastradero, and 23 night-time spaces on the
south side primarily in front of the Terman and Day School sites. Cycling facilities on the
south side of Arastradero would be upgraded, however, by providing a 24-hour bike lane
where currently there is a daytime-only bike lane. While the parking spaces removed are
used infrequently, residents who abut Arastradero near this intersection have expressed
CMR:369:02 Page 1 of 7
concern about shifting the travel lane closer to their homes. Staff anticipates enhanced
traffic safety for all modes of travel and reduced traffic congestion on Arastradero through
the creation of left-turn pockets and signal phases at the Arastradero-Donald/Terman
intersection. Staff proposes to do this without widening curb-to-curb pavement width or
eliminating the existing bicycle lanes at this location.
CMR:369:02 Page 2 of 7
RECOMMENDATION
Staff recommends that City Council approve the attached resolution authorizing the
establishment of no parking zones on the north and south sides of Arastradero Road for a
distance of 300 feet to the east of the easterly crosswalk at Donald and Terman Drives; and
for a distance of 165 feet to the west of the westerly crosswalk.
BACKGROUND
In the past few years, staff has received multiple complaints about problems due to drivers
making left turns from Arastradero Road to Terman Drive and (to a lesser extent) Donald
Drive. There are no left-turn lanes or signals at that intersection. Staff reviewed the crash
history and found that a substantial number of crashes related to left-turn movements have
occurred at this intersection since 1985o In 1997, the Mid-Peninsula Jewish Community Day
School submitted a development application for a new facility with access on Terman Drive.
Because the Day School was going to substantially increase left-turning traffic to Terman
Drive, the City required the applicant to fund its proportional share of new left-turn lanes
and signals, which will be constructed by the City. The new lanes will require that parking
be prohibited along both sides of Arastradero Road, which requires Council approval.
Staff first sent the no parking zones request to Council on October 4, 1999, with a
recommendation that Council refer the issue to the Planning and Transportation
Commission (Attachment C, CMR:375:99). The Commission discussed this issue at great
length on November 10, 1999. The Commission’s primary concern was the impact on
residences on the north side of Arastradero Road, especially the removal of parking.
Nevertheless, the Commission recommended that Council approve the resolution submitted
by staff. The Commission also requested that staff prepare for Council consideration an
alternate proposal with narrower lanes in order to preserve nighttime parking on the north
side of Arastradero Road. The Commission stated that, if staff believed this alternate
proposal was safe and workable, this would become the Commission’s preferred plan. The
Commissioners did not request that the alternate proposal be brought back to them.
Commissioners also requested that staff prepare several other alternatives that might lessen
the parking impacts and provide that information to the Council for its consideration. In
April 2000, staff prepared that information, but the left-turn project was halted at that point
due to news that Terman Middle School might reopen on the site, replacing the Jewish
Community Center (JCC). This major change in use would potentially change the site
access and!or trip generation.
The site plans and EIR for Terman Middle School have now been completed and approved,
with the school scheduled to open in September 2003. The number of peak hour westbound
Arastradero left-turns into Terman Drive will be slightly higher than with the JCC
occupancy of the site. One of the mitigation measures in the Terman School EIR is that the
City install left-turn pockets and signal phasing at the Arastradero/Terman/Donald
intersection before the school opens. The Transportation Division has determined that the
length of the left-turn pockets proposed earlier in 1999, and hence the length of the proposed
CMR:369:02 Page 3 of 7
-no parking zone, will still be sufficient for the change in use, except the length of the pocket
and the associated no parking zone to the west of the westerly crosswalk can be reduced
from 200 feet to 165 feet.
DISCUSSION
Staff has determined that the April 2000 alternatives analysis is valid for compariso.n
purposes with the new use on the Terman site, and it is included as Attachment B. Staff’s
proposed restriping plan recommended for approval by the Planning and Transportation
Commission is referred to as Alternative 1. (This alternative is the basis of Exhibit A of the
resolution--Attachment 1). The alternative favored by the Commission (if workable), to
narrow all lanes in order to preserve some parking, is referred to as Alternative 2.
Alternatives 1 and 2 are illustrated in Attachment B and discussed in the following
paragraphs. A comparison table of all alternatives is included in Attachment B.
Alternative 1: Staff’s Proposed Plan. Arastradero varies in width from 58.3 feet to 60 feet
from curb to curb. It is striped with four 10-foot vehicle lanes, a 13-foot bicycle/parking
lane on the north side and a seven-foot bicycle lane on the south side. Parking is allowed in
the south side bicycle lane only at night (7:00 p.m. to 7:00 a.m.). When cars are so parked, it
is not usable as a bike lane. Alternative 1 consists of adding a left-turn pocket in each
direction on Arastradero Road at the Terman/Donald intersection, with protected left-turn
signal phasing. In order to install the left-turn pockets within the existing traveled way,
bicycle lane widths would be reduced to five feet on both sides of Arastradero. Parking
would be eliminated as shown in Exhibit A. On the north side of Arastradero, approximately
eighteen 24-hour parking spaces would be eliminated along the fronts and sides of
residences. This parking area is only occasionally used. On the south side of Arastradero,
approximately 23 night-time parking spaces would be eliminated, primarily in front of the
Terman and Day School sites. The side of one residence would be affected. Again, these
spaces appear to be only occasionally used. All traffic lanes would be 10 feet wide (left-turn
lanes 9.5 feet), which is the minimum desirable width for an arterial street. Five feet is the
minimum acceptable bike lane width; Palo Alto usually provides at least a six foot bike lane
width on major roadways. This alternative upgrades cycling facilities, however, by
providing a 24-hour bike lane on the south side of Arastradero, where currently it is a
daytime-only bike lane.
Alternative 2: Planning Commission Proposal--Narrow All Lanes to Preserve Parking on
North Side. Given the existing 60-58.3 foot-wide curb-to-curb width of Arastradero, no
design with nine or 9-1/2-foot lane widths can provide sufficient width to maintain 24-hour
parking on the north, side of Arastradero. With all traffic lanes at 9-1/2 feet in width,’ the
south side bicycle lane would still have to be five feet wide as in Alternative 1. Thus, for
both Alternatives 1 and 2, 23 night time parking spaces would be lost on the south side of
Arastradero in front of the Terman and Day School sites and the side of one residence. The
north side bicycle lane with Alternative 2 would be 7 feet wide (versus 5 feet in Alternative
1), which would then allow parking in the bike lane at night only (7:00 p.m. to 7:00 a.m.).
CMR:369:02 Page 4 of 7
The bike lane is not usable when cars are parked in it. These 18 spaces would still be lost
during the day. Alternative 2 gives residents a slightly wider buffer between moving traffic
and their homes than Alternative 1 (an issue raised by some residents). Thus, Alternative 2
would partially address the concerns of some Arastradero Road residents about staff’s
proposal, and it addresses a Commission concern about maintaining some parking on the
north side of Arastradero. However, staff does not support sub-10-foot traffic lanes on an
arterial road, especially adjacent to minimum-width bicycle lanes. Safety concerns with
regard to such lanes are especially acute as regards trucks and transit buses in the travel lane
adjacent to the bike lane. Arastradero Road is a school commute corridor and carries heavy
vehicle traffic. Staff concluded that the advantages to residents do not outweigh the potential
negative safety impact of narrow lanes on drivers and bicyclists.
Other Alternatives. Attachment B discusses four other alternatives that the Commission
requested be provided for informational purposes for Council review:
Alternative 3: Add new left-turn lane in westbound direction only (i.e., for Terman Drive
only). This is an unconventional design which is contrary to. driver expectations and,
thus, may be confusing and result in potential safety problems.
Alternative 4: Widen south side of Arastradero Road and add east and westbound left-
turn lanes while maintaining existing parking. This alternative increases curb-to-curb
pavement width and project costs, and is not consistent with Comprehensive Plan
policies.
Alternative 5: Split the east and westbound Arastradero signal phases so that left turn
lanes are not needed and no restriping would be necessary and no loss of parking would
result. This alternative would cause excessive back ups, resulting in potential safety
problems and traffic shifting to parallel streets.
Alternative 6: Consider maintaining the status quo if the crash history is not substantially
different from other similar locations and/or if the accident history is mostly minor
. property-damage-only.
After examining all the alternatives, staff still supports only the original proposal--
Alternative 1. This design maintains minimum desirable and typical design standards for
left-turn pockets and phasing at intersections. Alternative 1 is the safest alternative, in that it
provides the maximum potential reduction in left-turn and left-turn related accidents, as well
as retains safe widths for bike lanes and adjacent through lanes. Alternative parking for
residents is available on the side streets, although it is not as .conveniently located. The
demand for parking in this area by residents is not high. The north side traffic lane would be
eight feet closer to residences, but Alternatives 2 and 3 reduce that impact only marginally.
CMR:369:02 Page 5 of 7
RESOURCE IMPACT
The estimated construction cost of this project has increased substantially from staff’s
estimate provided in CMR:375:99, to a total of $220,000. This estimate is based on bids
received recently for a similar project. This includes all signal, striping, signing, gutter and
handicapped ramp work. It also includes a new signal controllerand cabinet as well
necessary relocation of a utility box. Furthermore, the bxisting signal must continue to
function while the new signal is being installed. The full project will be funded from the
Electric Utility Capital Improvement Program. As a condition of approval of the Jewish.
Community Day School project, the Day School will reimburse the City for $20,300 of the
project cost.
TIMELINE
The timeline to have the new signal installed by August 2003, to be in place before Terman
Middle School opens, is already very short. As a result, staff has begun designing the new
installation assuming that Council will approve the no parking zones. Any delay in this
schedule for consideration of other alternatives would jeopardize the installation date. Staff
anticipates that construction would start in July 2003 and be completed by the end of August
2003.
ENVIRONMENTAL REVIEW
This project is categorically exempt from the California Environmental Quality Act (CEQA)
under Section 15301 of the CEQA Guidelines (minor alterations to existing facilities).

EXHIBIT A: NO PARKING ANY TIME TERMAN/ARASTRADERO INTERSECTION
ATTACHMENT B
DISCUSSION OF ALTERNATIVES FOR ADDING LEFT-TURN LANES
ON ARASTRADERO ROAD AT TERMAN/DONALD DRIVES
Notes: Refer to the comparison table at the end of Attachment B. The data used in this
discussion, including crash analysis, has not been updated since it was prepared in April
2000. This does not change the validity of this comparison of alternatives.
Alternative 1: Original Staff Proposal-- 10-Foot Lane Widths (Figure 1)
This alternative is illustrated in Figure 1 and is the basis for Exhibit A of the resolution
approving No parking zones. This alternative is discussed under "Project Description and
Alternatives" in this staff report.
Alternative 2: Planning Commission Proposal --Reduced Lane Widths (Figure 2)
This alternative is illustrated in Figure 2. This alternative is discussed under "Project
Description and Alternatives" in this staff report.
Alternative 3: Add new left-turn lane in westbound direction only (i.e., for Terman Drive
only) (Figure 3).
During the AM and PM peak hours, the sum of westbound left turns into Terman Drive
(with JCC present) is 279 vehicles, and the sum of eastbound left turns into Donald Drive
is only 15 vehicles (the latter is five percent of the total). Of the 32 left-turn and left-turn-
related accidents at the intersection, 23 were caused by left turns into Terman, and nine
by left turns into Donald (the latter is 25 percent of the total). The volume of eastbound
left turns into Donald and the associated accident history do not support a left-turn pocket
and phase for this direction. When left-turn pockets and phaSing are installed on a major
road, they are typically installed in both directions because they are warranted by the
turning volumes or accident history. At Arastradero/Terman/Donald, staff has
recommended left-turn facilities in both directions primarily to avoid potential driver
confusion. With left-turn facilities only in the westbound direction, some eastbound
drivers might think they could make protected left turns because they see westbound
drivers doing it. Driver confusion could lead to possible safety problems. There are no
locations in Palo Alto where a left-turn pocket and phase are installed in one direction
only. At the Alma/Churchill intersection, left-turn pockets are present for north- and
southbound Alma. But, up until a few years ago, a protected left-turn signal phase (green
arrow) was provided only in the northbound direction because the number of southbound
left turns was so small. Over the years, this caused confusion for southbound drivers and
caused enough accidents that a left-turn signal phase Was also installed for the lightly-
used southbound direction.
Commissioners noted that the eastbound Arastradero left-turn pocket and signal phase are
not truly necessary for volume or accident reasons, and asked if they could be deleted
Attachment B Page 1 of 7
from staff’s proposal. Their hope was that this would enable a portion of the westbound
bike lane to remain wide enough for nighttime parking, or even to remain available for
full-time parking. Staff therefore prepared Alternative 3, as illustrated in Figure 3. This
altemative results in full loss of only ten of the existing 18, 24-hour parking spaces on the
north side of Arastradero. Of the eight remaining, six will be for nighttime only and two
are 24-hour spaces. On the south side of Arastradero only 15 of the 23 nighttime spaces
are lost. In summary, this alternative preserves, in some form, 10 of the existing 18 north
side parking spaces that would be lost under Alternative 1. These are the spaces that the
Commission and residents were most concerned about. Staff does not believe that the
benefits to residents override the concerns of driver confusion and possible resulting
negative safety impacts.
Alternative 4: Widen south side of Arastradero Road and add east and westbound left
turn lanes while maintaining existing parking_
The Commission asked whether the south side of Arastradero Road in front of the
Terman and Day School sites could be widened to provide space for the new left-turn
lanes. This could allow the existing westbound through lanes to remain where they are,
thus reducing or eliminating negative impacts on residents on the north side of
Arastradero. Staff estimates that this widening would cost at least $200,000, not
including the cost of right-of-way acquisition in froflt of the Day School. This cost would
be in addition to that of the signal and restriping work. The landscape strip, which "
includes several mature trees, would have to be eliminated. Due primarily to the high cost
and lack of right-of-way, staff did not investigate this idea in further detail, and does not
recommend this alternative.
Alternative 5: Split the east and westbound Arastradero signal phases so that left tun,
lanes are not needed and no restriping would be necessary/and no loss ofp~rking wouhl
result.
The Commission did not promote this alternative design, but staff believes it deserves
brief mention. Instead of restriping lanes, removing parking, and performing major signal
work, the east-west signal phasing could simply be split. This means that all westbound
traffic on Arastradero Road (including left turns) would have an exclusive phase,
followed by an exclusive phase for all eastbound traffic (including left turns). The third
phase for Donald and Terman Drives would remain as it is. No changes would need to be
made to the layout of traffic and bicycle lanes or parking areas. This would be a simple
way to eliminate left-turn conflicts on Arastradero Road. Split phasing is commonly used
where traffic volumes are high and right-of-way is so constrained that additional lanes
cannot be added (examples are the East Meadow Drive and Charleston Road intersections
with Alma Street). The primary drawbacks are longer queues and congestion due to the
increased signal cycle time. At Arastradero/Terman, existing AM level of service (LOS)
A (before arrival of Terman School) would degrade to LOS C (after arrival of Terman
School and with split phase). The maximum peak-hour queue for westbound through
traffic could reach three blocks, and potentially more when pedestrians are crossing
Attachment B Page 2 of 7
Arastradero. Though LOS C is acceptable, the expected long queues would significantly
worsen traffic congestion in this area, possibly leading to greater shortcutting traffic
along the Maybell corridor. (For comparison, after arrival of Terman School and with
staff’s Alternative 1, AM LOS would be B.) Comprehensive Plan Policy T-39 generally
supports Alternative 5 ("To the extent allowed by law, continue to make safety the first
priority of citywide transportation planning. Prioritize pedestrian, bicycle, and automobile
safety over vehicle level-of-service at intersections."). However, staff does not
recommend this option, due to the increased potential "for driver frustration and
consequent commute traffic intrusion on neighborhood streets.
Alternative 6: Possibly consider maintaining the status quo if the crash history is not
substantially different from other similar locations and/or if the crash history is mostly
minor property-damage-only
As requested by the Commission, staff updated and expanded the crash analysis that was
presented in CMR:375:99. The Commission did not actually state that they might
consider recommending no action. But they seemed to imply that the left-turn pockets
should only be installed if the crash history clearly indicated unique and serious
problems. Between January 1985 and March 2000, 23 broadside crashes occurred
between left-turners and opposing through drivers on Arastradero Road. An additional
nine rear-end accidents occurred due to through drivers hitting drivers stopped in the
inside through lane to make left turns. Of this total of 32 left-turn and left-turn-related
accidents, only five also involved pedestrians or bicyclists in addition to the vehicles. Of
the 32, 10 involved relatively minor injury, with the remainder being property damage
only.,This ratio mirrors that on a citywide annual basis.
During this same 15-year period, a total of 57 accidents of all types occurred on all four
legs of this intersection (including the above 32). The breakdown of the types of
violations for most of this 57-accident group is shown graphically in Figure 2. "Auto
right of way" is the primary type of violation for a left-turn (broadside) crash. The
primary type of violation causing left-turn-related (rear-end) crashes is "unsafe speed".
The total of 57 accidents, when computed as a rate per million vehicles entering the
intersection, places the Arastradero/TermaniDonald intersection at about tenth worst in
the City, which is a poor ranking. Installation of the proposed left-turn lanes and signal
arrows is a wise improvement for this location, because it directly addresses the largest
clearly identifiable causal group of accidents.

PLANNING COMMISSION
FROM:CITY MANAGER DEPARTMENT: PLANNING
DATE:October 4, 1999 CMR: 375:99
SUBJECT:RESOLUTION APPROVING NO PARKING ZONES ON
ARASTRADERO ROAD AT TERMAN DRIVE
REPORT IN BRIEF
Due to the substantial number of accidents related to left turns from Arastradero Road to
Donald and Terman Drives, staff recommends that left-turn lanes and signal arrows be
installed on Arastradero Road at this intersection. The accident problem will be exacerbated
by added traffic from full occupancy of the Mid-Peninsula Jewish Community Day School
adjacent to Terman Drive. In order to provide sufficient width on Arastradero Road to add
the left-turn lanes, the gutters must be narrowed and parking must be removed on the
eastbound and westbound approaches to this intersection. Council approval is required to
establish the new No Parking zones.
CMR:375:99 Page 1 of 4
RECOMMENDATION
Staff recommends that Council refer to the Planning and Transportation Commission the
proposed establishment of No Parking zones on the north and south sides of Arastradero
Road for a distance of 300 feet to the east of the easterly crosswalk at Donald and Terman
Drives; and for a distance of 200 feet to the west of the westerly crosswalk, for discussion
and recommendation.
BACKGROUND
Terman Drive is the only vehicle access to the former Terman school site and the Terman
apartments adjacent to the site. Terman Drive is one leg of the four-legged Arastradero
Road/Terman Drive/Donald Drive intersection, located approximately midway between E1
Camino Real and Foothill Expressway. At this location, Arastradero Road has four traffic
lanes, an eastbound bicycle lane with no parking permitted between 7 a.m. and 7 p.m. any
day (except five minutes for commercial vehicles), and a westbound bicycle lane with.
parking permitted at all times.
In the past few years, the Transportation Division has received complaints about problems
related to drivers making left turns from Arastradero Road to Donald and Terman Drives,
where there are neither left-turn lanes nor left-turn signals. Staff reviewed the accident
history and found that a substantial number of accidents related to left-turn movements have
occurred at this intersection since 1985. Twenty accidents occurred directly between left-
turners and opposing through drivers where there are infrequent and/or inadequate gaps of
heavy peak period through traffic. An additional eight rear-end accidents occurred due to the
interaction between inattentive drivers and drivers stopped in the inside through lanes to
make left turns.
In 1997, the Mid-Peninsula Jewish Community Day School applied to the City to move and
expand its school (currently located on the Terman site) to a new location adjacent to the
Terman site. The Transportation Division and the project applicant looked at various
driveway options for the new school, and agreed that the best access would be via the
existing Terman Drive intersection. Because the expanded school will substantially increase
existing left-turning traffic, the City required the applicant to fund its proportional share of
the left-turn improvements which will be constructed by the City.
DISCUSSION
The existing traffic and bicycle lanes on Arastradero Road are already as narrow as possible,
so the additional width for the left-turn pockets must be obtained by removing parking on the
east and west sides of Arastradero. As shown in Exhibit A of the attached resolution, the
length of the new No Parking area will be 300 feet to the east of the easterly crosswalk; and
200 feet to the west of the westerly crosswalk (the distances are proportional to the number
of projected left turning vehicles). This parking removal will affect six residences--five on
the north side of Arastradero and one on the south side of Arastradero. All six residences are
corner properties and have frontages on side streets. Bus stops are located on Arastradero
CMR:375:99 Page 2 of 4
Road at this intersection. The addition of the left-turn lanes will result in five-foot-wide bike
lanes in which buses will stop, with the bus blocking part of the outside through-traffic lane.
This situation is unavoidable and is present in other locations in the City, including other
locations on Arastradero Road. In addition to the signing and restriping work that will be
needed to add the turn pockets, the width of the gutters on the north and south sides of
Arastradero must be reduced by one foot each in order to provide the minimum acceptable
width for the bike lanes. All curb, gutter, signing, striping, and signal work will be performed
by the City.
Staff sent a letter to residents living along the affected portion of Arastradero Road and to
residents of Donald and Terman Drives, explaining the project and its impacts and notifying
them of the October 4 City Council meeting. Staff also sent copies of this staff report to the
six households fronting on Arastradero Road. Staff has heard from three of the notified
households (the single affected household on the south side of Arastradero was not notified
of the proposed change in time to have any potential response included in this staff report).
One ~:esident of Donald Drive is concerned about increased traffic on her street that is already
occurring. The other two residents on Arastradero Road nearest t.he intersection are
concemed that narrowing the bike/parking lane on the north side of Arastradero will bring
traffic closer to their homes, thereby increasing noise and making it harder than it already is
to enter and exit their driveways. Left-tum driveway access may also be more difficult for
these two households because these residents will have to turn across the new left-tum lane
which may have more vehicles queued up than currently is the case. At least one of these
residents is also concerned that parking may be more difficult because spill-over parkers
from the Terman Community Center already use the north side of Arastradero Road and
Donald Drive. When parking is removed from the north side of Arastradero, some of these
parkers may move to Donald Drive or one of the other side streets, which are also the only
locations where residents of the six directly-affected households will be able to park (other
than their own driveways or garages). One of the concerned residents has a driveway that is
too short for parking without blocking the sidewalk.
Staffhas already received a complaint about the increased back-up of traffic entering Terman
Drive as a result of the recent opening of the new school. Staff believes that installation of
left-turn pockets and signal arrows is essential to avoid increased safety problems that could
result from the added traffic now using Terman Drive.
RESOURCE IMPACT
The estimated cost of the signal modifications is $65,000, plus $25,000 for the gutter,
signing, and restriping work, for a total of $90,000. As a condition of project approval, the
Jewish Community Day School will reimburse the City up to $20,300. The signal
modifications are budgeted in the Electric Fund. The gutter, signing, and striping work will
be implemented as part of the City’s annual resurfacing project, funded by existing Street
Improvement fund monies.
CMR:375:99 Page 3 of 4
POLICY IMPLICATIONS
This project is consistent with Comprehensive Plan Policies T-28 and T-39:
Policy T-28: Make effective use of the traffic~carrying ability of Palo Alto’s
major street network without compromising the needs of pedestrians and
bicyclists also using this network.
Policy T-39." To the extent allowed by law, continue to make safety the first
priority of citywide transportation planning. Prioritize pedestrian, bicycle, and
automobile safety over vehicle level-of-service at intersections.
TIMELINE
Left-turn pockets will be installed this fall, and left-turn signals will follow as soon thereafter
as possible.
ENVIRONMENTAL REVIEW
This project is categorically exempt from the California Environmental Quality Act
("CEQA") under Section 15301 of the CEQA guidelines (minor alterations to existing
facilities).
