MAYOR AND TOWN COUNCIL -
GREG LARSON, TOWN MANAGER /
SUBJECT: ACCEPT THE STATUS REPORT ON THE ROUTE 85 EXPRESS LANE
PROJECT.
RECOMMENDATION:
Accept the status report on the Route 85 Express Lane Project.
BACKGROUND:
In late 1990, the Town entered an agreement with the Santa Clara County Traffic Authority and
a separate agreement with Caltrans for the construction of Highway 85. The median of the
freeway was set aside at that time for future mass transportation development.
The Valley Transportation Authority (VTA) and Caltrans have developed a project to install
express lanes from Bailey Avenue along U.S. 101 in South San Jose and along Highway 85 to
the Highway 85/101 interchange in Mountain View.
DISCUSSION:
This project will convert the existing high occupancy vehicle (HOV) lanes, also known as
carpool lanes, to express lanes along the length of the project. In addition, the project will install
an additional HOV express lane between SR 87 and I -280.
The express lanes will act as dynamically priced toll lanes. Single occupant vehicles with a
transponder will be able to use the lanes for a fee. The fee will vary depending on the time of
day and traffic levels. Carpools with two or more occupants, motorcycles, transit buses, and
clean air vehicles with applicable decals will continue to use the express lanes free of charge.
Express lanes are a tool to manage congestion by utilizing existing capacity in the HOV lanes. A
VTA Fact Sheet is provided (Attachment 1).

MAYOR AND TOWN COUNCIL
SUBJECT: ACCEPT THE STATUS REPORT ON THE ROUTE 85 EXPRESS LANE
PROJECT
DISCUSSION (cont'd):
The project schedule includes a mid -2014 final design and a 2017 project completion. The
comment period associated with the environmental review has ended. The Town submitted
comments on the project environmental documents (Attachment 2). The Town's comments
reference a 1990 Highway 85 Performance Agreement between the Town and the County Traffic
Authority, which is attached for reference as well (Attachment 3). The VTA has not yet
requested the Town's written approval for the additional freeway lanes as specified in the 1990
agreement.
The addition of express lanes may have a minor positive impact on surface streets within the
Town, as some traffic shifts to the freeway instead of surface streets as a result of the additional
lane.
Neighbors near Highway 85 in Los Gatos, Saratoga, and Cupertino have raised strong concerns
regarding noise and other potential environmental impacts from the proposed Highway 85
project. The VTA has provided additional information on noise impacts to each jurisdiction. The
letter regarding the noise analysis in Los Gatos is provided (Attachment 4).
CONCLUSION:
Staff recommends that the Town Council accept the status report on the Route 85 Express Lane
Project and provide direction, as desired.
ENVIRONMENTAL ASSESSMENT:
This is not a project defined under CEQA, and no further action is required.
FISCAL IMPACT:
There is no fiscal impact.

State Route 85 Express Lanes Project
Overview
Lanes
The SR 85 express lanes project is within the central corridor of the Silicon Valley Express
Lanes Program being implemented by the Santa Clara Valley Transportation Authority
(VIA). This project will convert approximately 27 miles of existing High Occupancy Vehicle
(HOV or carpool) lanes to express lanes. The project will add a second HOV express lane
between SR 87 and 1 -280. The project limits are between U.S. 101 in Mountain View and
Bailey Avenue on U.S. 101 in south San Jose. The project will also convert the existing
HOV direct connector in south San Jose, from U.S. 101 to SR 85, to an express lane
connector.
Carpools with two or more occupants, motorcycles, transit buses, and clean air vehicles
with applicable decals will continue to use the express lanes free of charge. Solo drivers
will have the option of paying a toll to use the express lanes during commute hours.
Express lanes are a tool to manage congestion by utilizing existing capacity in the
HOV lanes.
SR 85 Express Lanes access points will accommodate traffic from 1 -280, SR 17,
SR 87, SR 237, U.S. 101, and potentially county expressways and other major
arterials. SR 85 connects commuters from San Jose,
Los Gatos, Cupertino, Saratoga, Campbell, i 1 9
Sunnyvale, Los Altos, and Mountain View (1)
to the technology and professional service
industries in Santa Clara County.

T Express lanes are separated from
regular lanes by a double white
painted buffer.
Electronic signs display the current toll
for solo drivers with FasTrak. Toll will
vary based on the level of congestion in
the express lanes and will be adjusted
to maintain free - flowing traffic.
An overhead antenna reads a FasTrak
transponder and the correct toll is
automatically deducted from prepaid
FasTrak accounts.

• Increased efficiency of existing roadway: Existing carpool lanes have the available capacity to accommodate more vehicles.
More efficient use of existing roadways is accomplished by encouraging transit and carpools, and allowing solo drivers to pay a
fee to access the lanes.
• Fast, reliable travel: Through the use of dynamic pricing, VTA can manage the amount of traffic in the express lanes and maintain
free- flowing speeds even when the general purpose lanes are congested. Motorists who choose to use the express lanes will
benefit from reliable travel times.
• Revenue reinvested In the corridor: Revenue from tolls would maintain the facility, enhance transit improvements, and provide
enforcement by the California Highway Patrol.
Schedule
Early 2014: Project approval and environmental documents complete
Mid 2014: Begin final design pending funding
Early 2017: Open express lanes for service pending funding

Staff from the Town of Los Gatos has reviewed the project information and has the following
comments:
• The proposed addition of second express lane is not noted in the Caltrans "Notice of
Intent to Adopt a Negative Declaration" dated December 27, 2013. See attached.
• In the initial study for the negative declaration, the addition of second express lane is not
noted in the "Project Description" on the front page under "Proposed Negative
Declaration ", on page i under "Summary ", nor on page 1 of the report under
"Introduction ". One can only find the project includes adding a second express lane in the
detailed discussion in the report.
Under the "Route 85 Performance Agreement signed in 1990 between Traffic Authority
(former VTA), and the Town of Los Gatos, it was agreed that "Route 85 through the
TOWN will be a 6 -lane facility with a median width of 46' from Winchester Boulevard
to Pollard Road, and 48' from Bascom Avenue to Winchester Boulevard; and a vertical
profile as shown in Attachment "A "." This agreement would need to be resolved.
• Also under the same agreement, "The Traffic Authority agrees that no new freeway lanes
shall be constructed in the Route 85 median or in the shoulders of Route 85 within the
geographical limits of TOWN without prior written approval by the Town Council of the
TOWN."
The Town will continue to participate in the planning and design process for the future of Route
85. If you have any questions or if you may need any assistance from Town staff, please feel free
to contact me or call Jessy Pu, Town Traffic Engineer, at 408 - 395 -2859.

THIS AGREEMENT, made and entered into this clay of October 1990, by and
between the SANTA CLARA COUNTY TRAFFIC AUTHORITY (herein referred to as
"TRAFFIC AUTHORITY "), and the TOWN OF LOS GATOS (herein referred to as
'"TOWN'),
WITNESSETH:
WHEREAS, in 1984 the voters of Santa Clara County passed Measure A on the
ballot, authorizing a one -half of one percent sales tax in the County for a period of ten
years, to fund major highway improvements on State Routes 85, 101, and 237, and
WHEREAS, the TRAFFIC AUTHORITY was created to administer the program and
see that specific identified improvements were implemented; and
WHEREAS, through the development of Freeway Agreements, it became evident that
a separate Agreement was appropriate between the TOWN and the TRAFFIC
AUTHORITY which would outline mitigation measures establish specific design guidelines,
and specify TOWN participation in the design process; and
WHEREAS, the TRAFFIC AUTHORITY intends to provide equitable application of
policies and measures for all Corridor cities in the implementation of the Route 85 freeway
project; and
WHEREAS, it is the mutual desire of the parties hereto to enter into this Performance
Agreement in accordance with the attached information;
NOW, THEREFORE, IT IS AGREED:
1. This Agreement is executed in conjunction with the separate Freeway Agreement
between the TOWN and the CALIFORNIA DEPARTMENT OF TRANSPORTATION
(herein referred to as "CALTRANS ").
2. This Agreement, by reference, incorporates the following documentation: the
TRAFFIC AUTHORITY'S Draft Strategic Plan July 1990, the Route 85 Environmental
Impact Statement. July 1987, and subsequent Reevaluations /Addenda; the Mitigation Plan.
December 1987, the Los Gatos Creek Mitigation Plan, July 1990; the Visual Design

Attachment 3
3. The general alignment of Route 85, along with street closures and interchange
locations, will be addressed in the Freeway Agreement between the TOWN and
CALTRANS.
4. Route 85 through the TOWN will be a 6 -lane facility with a median width of 46'
from Winchester Boulevard to Pollard Road, and 48' from Bascom Avenue to Winchester
Boulevard; and a vertical profile as shown in Attachment "A ".
5. The TOWN has participated in the development of corridor visual design
guidelines through a committee composed of representatives from Route 85 communities.
From this effort, a general design theme was specified and design guidelines were prepared.
These guidelines address prospective visual aesthetics of design features such as retaining
walls, sound walls, bridges, pump stations, community walls, landscaping and related
amenities. The guidelines shall be followed in the final design of freeway facilities.
Attachment "B" represents alternative surface treatments selected by the TOWN for use in
final design of the features listed herein.
6. Attachment "C' defines tentative locations for sound attenuation along the Route
85 corridor, as shown in the Mitigation Plan. Sound walls will be designed and constructed
in accordance with Federal and State guidelines as a minimum. The TOWN will provide
input during the design process through community meetings and review of design
documents.
7. The TRAFFIC AUTHORITY will provide levels of landscaping over and above
those required by Federal and State standards. Specific types and locations will be
determined in the design process, with input from the Aesthetics Review Committee and
approval by the TOWN. Landscaping design will seek to maximize local aesthetics, and
minimize long -term maintenance costs, within the available budget.
The TRAFFIC AUTHORITY'S allowance for landscaping is $25,000 per landscaped
acre, and community input will determine the design emphasis. The area to be landscaped
is the width from the edge of the outside shoulder to the limits of the right -of -way and
excludes the median. The cost of required irrigation is included in the $25,000 per acre
allowance. Attachment "D" provides graphic representation of 5 major areas of typical
freeway landscaping: (1) Depressed profile (2) Elevated profile (3) At -grade profile
(4) Local street interchange (5) Major freeway -to- freeway interchange. These displays
demonstrate typical densities and general layouts of ground cover. The TOWN will direct
the allocation of the landscaping allowance within its boundaries, consistent with the Visual
Design Guidelines. Any landscaping damaged or removed from a local street shall be
replaced consistent with Town policy. The size of the replacement species shall be
approved by the Town.

8. The TRAFFIC AUTHORITY agrees to set aside sufficient funds in an escrow
account to be maintained by the County Controller as part of the County's pooled
investment fund, to cover the cost of mitigation measures within the TOWN over and above
that mitigation which would be provided under State and Federal guidelines.
9. CALTRANS has developed a visual theme for Route 85 bridges which utilizes a
tapered, rounded box structure and pier. The TOWN may include aesthetic, non - structural
changes to enhance a preferred local theme. Bridges will be designed and constructed in
a manner not to preclude future mass transit development in the freeway median.
10. Local historic, archaeological and cultural resources impacted by the freeway
project will be assessed and dealt with in accordance with the Environmental Jmpact
Statement and the Mitigation Plan. Attachment "C' defines potential pedestrian and bicycle
facilities and impacted historic sites in the Route 85 Corridor through the TOWN.
11. The TOWN will participate in the final design process through attendance at
regularly scheduled meetings. These meetings are held to coordinate the efforts of the
design team; to allow affected agencies to express their 'interests and concerns; and to
ensure consistency with current State and local standards, and the Visual Design Guidelines
12. The TRAFFIC AUTHORITY agrees to phase construction of the freeway in such
a manner that minimum segments to be opened to traffic are as follows,
• Route 280 to Route 17
• Route 17 to Almaden Expressway
• Almaden Expressway to Monterey Highway
• Monterey Highway to Route 101
In the event that this phasing becomes unattainable, the TRAFFIC AUTHORITY
and TOWN will develop a revised phasing plan, acceptable to both parties.
The TRAFFIC AUTHORITY also agrees to include Lark Avenue, from Oka
Lane to Los Gatos Boulevard, in an early construction phase.
13. Wherever feasible, soundwalls will be included in an early construction phase
where they do not interface with other and subsequent construction activity.
14. The TRAFFIC AUTHORITY agrees that no new freeway lanes shall he
constructed in the Route 85 median or in the shoulders of Route 85 within the geographical
limits of TOWN without prior written approval by the Town Council of the TOWN.

23. The TOWN agrees to widen Los Gatos Boulevard to six lanes and proposes, as
an interim measure, to widen Los Gatos Boulevard to four lanes between Lark Avenue and
Samaritan Drive prior to the completion of the Bascom Avenue interchange. The TOWN
will plan for the four lane project in the 1991 -1992 Capital Improvement Program. The
six lane widening would be constructed when development of the impacting properties
within the Routes 85/17 Project Referral Boundary takes place and are assessed for said
improvements. That assessment of improvements by parcel shall be proportional based on
the relative degree of impact as determined by the projected traffic generation of specific
development projects. Assessment shall also cover the cost of necessary traffic mitigation
measures caused by said development within the Project Referrai Boundary.
24. This Agreement may be modified at any time by the mutual consent of the parties
hereto, as may become necessary for the best accomplishment, through TRAFFIC
AUTHORITY and TOWN cooperation, of the whole freeway project for the benefit of the
people of Santa Clara County and the TOWN. If unforeseen cost increases or significant
L4 \agreemnt\perf.agm 5 Rev. October 18, 19m 12.39
environmental impacts arise beyond those anticipated by this Agreement, each party
reserves the right to request an Amendment to this Agreement. If reasonable, these
requests will be considered, but in no event is the TOWN under any obligation to approve
such amendment.
25. TRAFFIC AUTHORITY agrees to defend, indemnify, and hold TOWN harmless
against any and all claims, damages, losses, demands, or causes of action arising out of any
negligence or intentional misconduct on the part of the TRAFFIC AUTHORITY, its
agents, employees, attorneys, assignees, or contractors in the course of performing this
Agreement. The indemnity provided by this paragraph shall include reimbursement of all

Re: SR 85 Express Lanes Project: Noise Analysis Results for the Town of Los Gatos
Dear Roy:
As discussed at our February 26 meeting about project - related noise, we are providing figures
with noise measurement locations and tables of noise measurements and predictions for SR 85 in
the Town of Los Gatos based on the 2012 Noise Study Report (NSR) for the SR 85 Express
Lanes Project. In addition, as requested by the Town of Los Gatos, we are providing a
comparison of existing noise levels with predicted future noise levels from the 1987 Final
Environmental Impact Statement (EIS) for the construction of SR 85.
1.0 RESULTS OF THE 2012 NOISE STUDY REPORT
The SR 85 Express Lanes Project noise analysis divided the project corridor into study segments,
as described in the 2012 NSR. The Town of Los Gatos straddles Segments 7 and 8. Traffic noise
modeling results and predicted traffic noise impacts for evaluated locations in the Town of Los
Gatos are shown in Table 1. This table is based on NSR Tables 6 -2, 7 -8, and 7 -9. The evaluated
locations are shown on attached Sheets 1 through 3.

Both receptor locations currently receive acoustic shielding from noise barriers. Therefore, the
2012 noise data are compared to the 1987 predicted "future peak hour mitigated" level. The 2012
existing and future No Build noise levels are 1 decibel below the 1987 future peak hour
mitigated level, and the 2012 future Build noise level is the same as the 1987 predicted level.
These results indicate that the 1987 modeling is consistent with current measurements and
predicted levels at this location.
Please feel free to contact me at any time if you have questions or need further assistance.
Sincerely,
