CC 2015-03-10_10a Alternatives for Brisco Rd Interchange Project PresentationITEM 10.a
CONSIDERATION OF ALTERNATIVES FOR THE BRISCO ROAD-HALCYON ROAD/HIGHWAY 101 PROJECT
AND AMEND CONSULTANT SERVICE AGREEMENT TO EXTEND THE TERM FOR WOOD RODGERS, INC. AND POINT C
1
OVERVIEW
Brisco Interchange Project has been underway for 15± Years.
Numerous Design Alternatives have been analyzed.
Currently we have three alternatives under evaluation.
2
HISTORY
In 2001, a Project Study Report-Project Development Support (PSR-PDS) was completed to develop alternatives to improve operation of the Brisco Road-Halcyon Road/U.S. 101 Interchange.
The project moved from the PSR-PDS phase to the Project Approval and Environmental Determination (PA&ED). In the PA&ED phase, additional design alternatives were prepared.
3
HISTORY
In August 2008, design alternatives were presented to City Council.
In October 2010, City Council approved including Alternative 4 in the PA&ED process. Alternative 4 involves moving
the Brisco northbound on-ramp and off-ramp to Rodeo Drive.
4
HISTORY
In March 2012, the California Transportation Commission programmed $5.6 million in construction funding for the project.
In December 2013, Caltrans, Consultants and staff met in Sacramento
to review comparison interchanges, and geometrics for Alternative 4 and what would be needed for approval of design exceptions. The result of the meeting was the identification of
Alternative 4C.
5
HISTORY
In March 2014, the City Council approved a revised intersection treatment for Alternative 4C to include a roundabout and consultant contracts to complete necessary studies.
In August
2014, an additional $1,000,000 was recommended by SLOCOG to the California Transportation Commission (CTC) for the construction phase of the project to increase the total grant funding
to $6.6 million.
6
HISTORY
In January 2015, the Brisco Subcommittee met with Caltrans and SLOCOG officials. During the meeting Caltrans staff outlined remaining concerns with Alternative 4C. A Project Development
Team (PDT) meeting was determined necessary to determine final alternatives that will go out for public review.
In February 2015, Caltrans furnished the City feedback on the Design
Exception Fact Sheets that caused staff significant concern regarding Caltrans opinion of the viability of Alternative 4C signal and roundabout. This concern is with regard to the posted
speed limit on West Branch Street being 40 MPH instead of 35 MPH.
7
ALTERNATIVES – ALT. 1
Orient – Grand Ave, 101, Brisco, and Camino Merchado
Improvement work at Grand Ave, Demolition work at Brisco, and improvement work at Camino Merchado
8
ALTERNATIVES – ALT. 1
Grand Ave Bridge will be widened to create two bike lanes both 8’ wide
South Bound on ramp will be relocated to better align with the south bound off ramp
9
ALTERNATIVES – ALT. 1
The North bound off and on ramps will be removed at Brisco Road.
10
ALTERNATIVES – ALT. 1
Camion Mechado will be widened to include dual left turn movements only 101 north bound
11
ALTERNATIVES – ALT. 1
This alternative relives congestion on Brisco Road.
Vehicles will be rerouted from Brisco to either Grand Ave or Camino Merchado.
Preliminary estimates for this work is $8.4 million.
12
ALTERNATIVES – ALT. 1 ROW
Alternative 1 will impact the Shell Gas Station on Grand Ave adjacent to the 101 North Bound on ramp.
Portions of the Shell gas station property are needed to construct alternative
1.
Impacts to business and operation are unknown at this time. One or two driveways maybe lost. Portions of the gas overhead shelter will need to be removed. Gas pump relocation
is likely necessary. Site circulation will need to be revised.
13
ALTERNATIVES – ALT. 4C SIGNAL
Orient – Grand Ave, 101, Brisco, and Camino Merchado
Improvement work at Grand Ave, Rodeo Drive, and Grace Lane
14
ALTERNATIVES – ALT. 4C SIGNAL
South Bound on ramp will be relocated to better align with the south bound off ramp
15
ALTERNATIVES – ALT. 4C SIGNAL
Brisco road north bound on and off ramps will be removed and relocated to West Branch Street
16
ALTERNATIVES – ALT. 4C SIGNAL
The intersection of Grace Lane and Rodeo Drive will be realigned.
17
ALTERNATIVES – ALT. 4C SIGNAL
This alternative relives congestion on Brisco Road.
Maintains similar traffic patterns by reestablishment of on and off ramps at West Branch Street.
Preliminary estimates for this
work is $15.4 Million
This alternative may not be viable since the posted speed limit on West Branch Street if 40 MPH and not 35 MPH
18
ALTERNATIVES – ALT. 4C ROUNDABOUT
Alternate 4C Roundabout is similar to 4C Signal except for the intersection of West Branch Street, Rodeo Drive / Grace Lane
Preliminary estimates for this work is $15.7 Million
Viability
of this alternative is not affected by the existing 40 MPH posted speed limit on West Branch Street
19
ALTERNATIVES – ALT. 4C
Alternate 4C will also require ROW acquisition from the County of SLO and parking lot work.
20
WHY ARE WE HERE?
Staff will be attending a Project Development Team meeting as a next step.
The PDT will be making recommendation for which project alternatives are available for public review and
comment.
Some alternatives may fall out of consideration.
Staff would like Council’s guidance.
21
WHY ARE ALTERNATIVES IMPORTANT?
Public review and comment helps to flush out unforeseen issues.
Alternative 1 seems to be the path of least resistance at this point, but future input might be cause to rethink. Alternative
1 impacts on an adjacent shell gas station might prove to be to large and costly or the change in circulation patterns might cause economic impacts to adjacent areas.
Alternatives
4C Signal is currently not considered viable by Caltrans since the posted speed limit on West Branch Street is 40 MPH and not 35 MPH. The speed limit may change on West Branch Street.
Proceed
to public review without signed Design Exception Fact Sheets with authorization from the District 5 Director.
Post the speed limit of West Branch Street at 35 MPH.
Alternative 4C Roundabout
while still believed to be viable at this point in time might fall out due to public concern over Arroyo Grande’s first roundabout in a well traveled area.
Having all options available
for public comment is transparent, inclusive, and might place the City in the best position if an alternative becomes none-viable.

CALTRANS
To Discuss Caltrans Process, I would like to introduce Tony Harris with Point C.
Tony is a Registered Civil Engineer.
Tony has worked for Caltrans for 15 prior to his exit into private
consulting.
Tony exited the Caltrans organization as the Chief Deputy Director and Acting Director of Caltrans.
Tony has been working with the City on this project since 2010.

Item 10.a
Questions?
24
Item 10.a
Hence, listing the comments directly related to each of the Mandatory and Advisory Design Exceptions associated with 4c RAB, and 4c Signal Intersection seems inappropriate. Quantity
and magnitude of the number of exceptions should be carefully balanced between with the proposed need to replace the N/B Brisco on and off ramps after closure.
