BACKGROUND
On November 8, 2011, the City Council approved the purchase of vacant land on Valencia
Boulevard west of McBean Parkway for a proposed park-and-ride facility and expansion of the
City's existing McBean Regional Transit Station.
The City has received approximately $4.7 million of both federal and local funds through the
American Recovery and Reinvestment Act and Congestion Mitigation and Air Quality
Improvement Program from the Federal Transit Administration and the Los Angeles County
Metropolitan Transportation Authority, respectively. These funds can be used for the preparation
of environmental documents, design, construction engineering supports, and construction of the
proposed park-and-ride facility.
After conducting several public outreach meetings and obtaining all necessary environmental
documents, staff is ready to begin the design phase. The final design of the proposed
park-and-ride facility, which will service local and commuter transit passengers and potential
rideshare passengers, will be based on the attached preliminary site plan. The facility will add a
total of 285 parking spaces, providing much needed public parking.
YFPRGFEI
Key components of the proposed park-and-ride facility include parking spaces, five new bus
canopies to serve commuter buses, landscape enhancements, low -impact site lighting, public art
installations, and transit operation service features. Other design components will include Low
Impact Development (LID) elements such as bio-swales, bio -detention basins, and permeable
pavement.
On September 27, 2011, staff sent out a Request for Proposal (RFP) to seven qualified
professional engineering firms that have previously worked with the City. The RFP asked firms
to identify their relevant experience in transit -related parking design projects, and to demonstrate
their technical approaches to the project scope. In addition, the City provided all RFP recipients
with copies of the preliminary designs, feedback from the community meetings, and staff
comments regarding this project for consideration when developing their proposals.
On November 10, 2011, staff received five proposals. Based on the initial evaluation, the top
three firms were invited to interview with the evaluation panel. The three highest scoring firms in
order were: AE COM, Tetra Tech, Inc., and Hunsaker & Associates.
During the interview, each firm was given an opportunity to present their "vision" for the
McBean Park -and -Ride and to demonstrate their understanding of the needs of the City. AE
COM and Tetra Tech, Inc., demonstrated a detailed understanding of those needs. Both firms
presented the interview panel with unique yet viable ideas and alternatives that could potentially
reduce both construction and on-going maintenance costs. Hunsaker & Associates submitted a
proposal with little emphasis on project specifics and brought few project -enhancing ideas to the
interview panel. It was this level of preparation, attention to detail, experience, and understanding
that resulted in the significant discrepency in the scoring between the top two and the
third -ranked firm.
Ranking Company Location Overall Cost Score
1 Tetra Tech, Inc. Irvine, CA $331,995 93.00
2 AE COM Los Angeles, CA $451,284 93.00
3 Hunsaker & Assoc. Santa Clarita, CA $313,861 76.00
The evaluation panel also considered the experience of each of the project teams and found that
both Tetra Tech, Inc., and AE COM had significant experience working similar projects.
Hunsaker & Associates, the third -ranked firm, has limited transit, public works design, or federal
project experience.
Tetra Tech, Inc., completed a project that included both design and construction engineering
support for over 1,000 parking spaces for the Los Angeles Zoo Parking Lot project. The project
required many of the same elements as the McBean Regional Transit Station including the
parking lot, LID design, and a construction sequence allowing the site to remain open and
operational during construction. Tetra Tech, Inc.'s expertise directly led to lower construction
costs and improved operations of the zoo parking lot.
The proposed AE COM team had performed various transit center projects in Southern
California, while the proposed Hunsaker & Associates team recently completed the design for the
"Iron Horse Trail" project located on Magic Mountain Parkway next to a Christmas tree site.
After considering the scoring from the written proposals and the results of the oral interviews,
staff recommends Tetra Tech, Inc., as the top qualified professional engineering services firm for
the completion of the design plans, specifications, and estimate. Tetra Tech, Inc., has previously
worked on various civil engineering design projects with the City's Capital Improvement
Projects division.
Tetra Tech, Inc., demonstrated the capabilities of their design team with a strong technical
background in civil engineering and transit operations experience, and a distinct mix of elements
which will contribute to the project site. The following elements were discussed in great detail in
their proposal and the oral interview: 1) Site Optimization, 2) Low Impact Development (LID),
3) Consideration of Community Comments, and 4) Performance on Comparable Projects.
Site Optimization
Tetra Tech, Inc., demonstrated an in-depth understanding of the project objectives with
enhancements to increase the effectiveness of the existing site plan. They have proposed
improvements to site grading and drainage, which will generate construction cost savings and
reduce maintenance costs by eliminating retaining walls and making beneficial drainage
modifications. Additionally, geometric enhancements are proposed, which will benefit on-site
circulation.
Low Impact Development (LID)
Tetra Tech, Inc., possesses in-depth LID experience. They presented recommendations to the
City on LID elements based on the preliminary site plan, which will provide improvements to the
project site.
Those recommendations include adding bio -detention basins, modifying bio-swales shown on the
site plan, and locating permeable pavement in the most beneficial areas.
These measures will reduce run-off, control sediment, and allow more room for planting trees.
These measures will also maximize the project sustainability goals, increase the effectiveness of
the permeable pavement, and reduce construction costs.
The design of the project's LID elements will meet or exceed the National Pollution Discharge
Elimination System (NPDES) and the City's Standard Urban Stormwater Management Plan
(SUSMP) requirements.
Consideration of Community Comments
During the review of the conceptual site plan, City staff completed extensive public outreach and
received community feedback primarily related to parking lot lighting impacts, landscaping, and
LID design elements mentioned above. Tetra Tech, Inc., explored these items and proposed
specific recommendations to address these concerns. Tetra Tech, Inc.'s design of the parking lot
lighting will not only consider energy efficiency, but will also minimize the visual impacts to the
surrounding neighboring communities. Lighting design and fixtures will comply with the Dark
Sky Ordinance.
In the interest of providing a well -landscaped site, Tetra Tech, Inc., proposes to complement the
plant palette and select specific fast-growing tree species on the west side for project shielding
purposes.

Participation of Local Firms -
Staff encourages hiring local firms by making every effort to reach out to local qualified
engineering firms in soliciting professional services proposals. The three above-mentioned firms
(Tetra Tech, Inc., AE COM, and Hunsaker & Associates) are either located in the City or propose
to work with local subconsultants for this project.
Tetra Tech, Inc., is investing locally by hiring local subconsultants, Pinnacle Land Surveying,
Inc., Gausman & Moore, and C.F. Engineering, Inc., for survey, electrical engineering support,
and potholing, respectively. In addition, they have obtained R.T. Frankian & Associates for
geotechnical support. R.T. Frankian & Associates has previous knowledge of the project site and
has performed various projects within the City.
Staff is confident the final design plans and specifications to be prepared by Tetra Tech, Inc., will
have a profound positive impact on construction cost, traffic and transit operations, and
post -construction maintenance of the project. Collectively, these benefits will allow the City to
deliver a state-of-the-art park-and-ride facility.
California Government Code 4526 prescribes selection of architectural and engineering services
to be based on demonstrated competence and professional qualifications necessary for the
satisfactory performance of the services required and does not authorize the selection of
professional architect and engineering services based on cost. The City was able to reach an
agreement with Tetra Tech, Inc., at a fair and reasonable price.
ALTERNATIVE ACTIONS
Other action as determined by the City Council.
FISCAL IMPACT
Adequate funds from ARRA Transit and Congested Mitigation Air Quality, Fund 700, were
previously appropriated into project expenditure account, T1012700-5161-001.
