FROM: Jay D. Walter, Director of Public Wor4q)ll
Prepared By: Chris Overby, Engineer II-Traffic
SUBJECT: FOOTHILL & TASSAJARA TRAFFIC SIGNAL MODIFICATION, .
SPECIFICATION NO. 90854
RECOMMENDATIONS
1 Approve plans and specifications for construction of the Foothill & Tassajara Traffic
Signal Modification Project, Specification No. 90854
2. Authorize staff to advertise for bids and the City Manager to award the contract if the
lowest responsible bidder is under the Engineer's Estimate of$306,000.
DISCUSSION
Improvements to the southwest corner of.Foothill & Tassajara were identified in the 2007-09
Financial Plan. The improvements include widening the corner radius to restore City transit
routes which were suspended due to conflicts with vehicles exiting Tassajara, an ADA accessible
pedestrian ramp and relocation of utilities that are in conflict with these improvements.
In addition to the transit issues, this intersection has been identified in the City's Annual Traffic
Safety Report for conflicts with vehicles turning left from Foothill, ranking number 5 in 2007
and number 4 in 2008. The intersection ranking is based on the collision rate in comparison to
other locations of similar classification. To address. the left turn conflicts, staff recommends
incorporating the traffic safety program recommendations to upgrade the traffic signal to include
a separate left turn phase, and install dedicated left tum lanes for traffic on Foothill by relocating
the two-to-one lane transition one block east-of its current location.
This project has taken longer than expected due to coordination with the private development at
399 Foothill and staffing resource issues. The private development project is to construct
additional improvements on both Foothill Road and Tassajara but due to the economy the public
improvements included in this bid package have been separated out and need to move forward
now. It is unknown when, or if the private project will be constructed. The construction
documents are now complete and ready to:advertise. Once approved, the bidding, award and
construction process is expected to be completed in approximately six months.
FISCAL IMPACT
The total Engineer's Estimate for the entire project is $373,200. The original scope of the
Foothill/Tassajara improvements identified in the 2007-09 Financial plan included improvements
only to the southwest corner. However, in order to provide an overall cost savings by combining
construction efforts, the traffic safety report recommendations have been incorporated into this
project. There is currently $111,600 available for construction in the project account. Funding for

the additional safety improvements will be provided by the General Traffic Signal Improvements
Account ($236,600), and the Traffic Safety Report Account ($25;000).
City Staff recommends the transfer of the necessary funding as identified in the table below to
the Foothill/Tassajara Improvements Account at the time of contract award. The respective
accounts, as identified above, are provided in detail in the following table.

ALTERNATIVES
1. Deny the project. The City Council could deny the project. However, staff does not
recommend this due to the potential safety improvements that will result from this
project. The documented collision pattern will likely persist and transit routes cannot be
restored until this project is completed.
2. Defer the project. The City Council could direct staff to defer the project until a later
date. However, staff does not recommend this because of similar impacts to the project
being denied. Staff recommends proceeding with the project now because the funding is
available and currently the construction market is very competitive.

FOOTHILUTASSAJARA INTERSECTION IMPROVEMENTS
CIP Project Summary
Making improvements to the intersection of Foothill/Tassajara will cost$125,000 in 2008-09.
Project Objectives
1. Increase radius on southwest comer to improve turning ability for large vehicles including SLO Transit
buses.
2. Install ramp that will meet Americans with Disabilities Act(ADA)and State requirements.
3. Relocate or underground utilities and storm drain§that are in conflict with improvements.
4. Coordinate work with private development to take advantage of one-time construction and potential costs
savings.
Existing Situation
The existing comer of Foothill and Tassajara has not been upgraded to current ADA standards. Although the City
has upgraded many comers in the vicinity of this location, the southwest comer of Foothill/Tassajara has been
deferred due to a high degree of utility conflict and other infrastructure that would make the improvements very
expensive. The existing handicap ramp does not meet current ADA standards and the small radius makes turning
for larger vehicles problematic. In 2007, SLO Transit (which had used this intersection for quite some time)
relocated its existing transit routes one block west because the small radius was causing conflicts with cars
exiting Tassajara onto Foothill. This conflict was being encountered more frequently which caused the bus routes
to get progressively further behind schedule. The relocation of the routes to the new section of Ramona Drive
caused concern from adjacent residents, who voiced numerous complaints to Council about having the bus routes
on their block.
Late in 2007, a proposal was submitted for redevelopment of the property on the southwest corner(399 Foothill)
that included some retrofit of the adjacent public right of way. The full scale improvement of the comer was
beyond the nexus of the development intensity so requiring all improvements be made by the development is not
possible. Instead staff has worked with the developer to pursue a cost sharing proposal to complete the
improvements as part of the redevelopment and complete both private and public improvements concurrently. As
pan of this arrangement, the developer agreed to dedicate the right of way for the necessary improvements to the
City at no charge.
On April 15". 2008 the Council reviewed an appeal of the Architectural Review Commission approval of the
project and ultimately determined to uphold the appeal without prejudice to allow the applicant the opportunity to
revise the project subject to Council suggestions that could make the project more consistent with the
neighborhood. The Council also directed staff to return with a 2008-09 Capital Improvement Program request to
complete this work.
Goal and Policy Links

PROJECT DESCRIPTIONS
Project Work Completed
A preliminary design and construction estimate to complete the work has been solicited from the developer's
engineer.
Environmental Review
The project will be completed in tandem with the adjacent development project which has received
environmental review and approval. As such,no formal environmental review will be required.
Project Constraints and Limitations
1. Staff will need to coordinate with nearby residents to alert them when improvements will commence and
potential temporary closures of the sidewalk will begin.
2. The project will be dependent on construction improvements and timing of the adjacent private development
project which will complete the public improvements at the same time as on-site work is constructed.
3. Utility relocation or undergrounding costs may exceed current estimations.
4. Relocation of the traffic signal equipment on the comer may be more costly if the existing conduit has been
damaged and can not be reused for rewiring of the intersection.
Stakeholders
Stakeholders include area residents, the adjacent property owner, utility companies and SLO Transit.

Key Project Assumptions
Cost projections are based upon an estimate provided to Development Review staff from the private
development's engineer. These estimates also assume that the development project on the southwest comer of the
intersection will submit a revised project and will ultimately receive approval by the Council and that the
applicant will still be amenable to a cooperative project.
The right of way modification project could become more costly if the utility relocation costs are higher than
expected (beyond City control) and if the existing traffic signal conduit cannot be reused to rewire the

intersection. The project costs have been estimated assuming the improvements will be incorporated into the
construction efforts of the adjacent private development project and the City will reimburse these efforts.
Project Manager and Team Support
Project Manager
Project management will come from the Development Review staff with assistance from the City Engineer and
inspection team.
Project Team
The project team will consist of staff from Public Works Engineering, Transportation and Development Review.
Alternatives
1. Deny the Project Denying the project will miss a one-time only opportunity to share costs with the adjacent
development for constructing the improvements. If the City has to complete the improvements at a later time
the costs may be increased and the location will undergo construction twice.
2. Defer or Re phase the Request. Deferral will essentially be the same as denial of the project as operational
and cost concerns will still be prevalent.
3. Do the project on our own. If the subsequent development project is not submitted or approved (and/or the
developer is no longer in a cooperative mood) the City will need to complete the improvements. This will
include the right-of-way (ROW) cost — and probably higher design, construction and construction
management costs.
Operating Program
Public Works Maintenance staff will maintain the improvements when complete. There will be no impact to the
maintenance budget since the comer sidewalk,curb and gutter and signal are all maintained by the City currently.
Project Effect on the Operating Budget
None.
