BACKGROUND
The City of Santa Clarita (City) owns approximately 12.5 acres of undeveloped property on the
northeast corner of the intersection of Soledad Canyon Road and Sierra Highway, which is the
future home of the Canyon Country Community Center. A Conceptual Master Plan was
presented to, and adopted by, the City Council at the June 28, 2016, meeting. The Canyon
Country Community Center is identified in the Building and Creating Community theme of the
City's strategic plan, Santa Clarita 2020.
This effort includes the Regional Stormwater Infiltration Best Management Practice (BMP)
System design and all supportive disciplines required to provide a complete set of construction
plans, specifications, and cost estimates for the construction of this Leadership in Energy and
Environmental Design certified project. The Regional Stormwater Infiltration BMP System will
collect stormwater and other runoff and direct it to a basin below the open turf area of the
Canyon Country Community Center for percolation into the groundwater.

similar projects; quality and experience of the project management team members; demonstrated
understanding of the project scope; and the ability to meet the required schedules. Michael Baker
International's cost proposal was low due to a lack of understanding of the complete scope of
work and did not include vital aspects of the design requirements.
Staff recommends awarding the contract to Psomas. Psomas demonstrated an in-depth
understanding of the project's needs, provided a detailed scope of work, and has extensive
experience with these types of projects. The requested contingency will cover any additional
design needs and modifications during the design process.
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. City staff was able to reach an
agreement with Psomas at a fair and reasonable price.
ALTERNATIVE ACTION
Other action as determined by the City Council.
FISCAL IMPACT
As part of the Fiscal Year 2017-18 budget, Stormwater (356) funds in the amount of $1,560,000
were appropriated in expenditure account R3007356-5161.001 to support this recommended
contract.

record drawings. We will work closely with City
staff to successfully complete the project within the
established budget and time schedule, while also
protecting the interest of the City.
PROJECT UNDERSTANDING
The City of Santa Clarita, in conjunction with Los
Angeles County, are implementing the Enhanced
Watershed Management Program (EWMP) to
comply with the requirements of the MS4 permit.
The EWMP allows collaboration between the
agencies on multi -benefit regional projects to retain
stormwater and non-stormwater runoff, as well as
facilitate flood control and water supply through
groundwater recharge.
The Canyon Country Community Center proposed
by the City of Santa Clarita is a collaborative project
that allows for flood control improvements and
management of stormwater and non-stormwater
runoff within the Mint Canyon Watershed. This
project includes improvements to the Mint Canyon
Channel that will be undertaken by the County of Los
Angeles, the Canyon Country Community Center
building and park facilities, and implementation of a
regional stormwater infiltration BMP that is located
beneath the park area of the community center.
Design Objectives
The specific design objectives of the infiltration BMP
located beneath the Canyon Country Community
Center park area are to intercept dry weather
flows in both the Mint Canyon channel and the
Sierra Highway storm drain lines, and capture
7.5 acre-feet of runoff which would include the
85th percentile storm event runoff from the Sierra
Highway watershed. A concept design of the BMP
as presented in the TetraTech Memo dated March
23, 2016, indicated the BMP should capture and
infiltrate a minimum of 2.2 acre-feet of runoff which
represents the runoff from the 85th percentile storm
event. The design volume of 7.5 acre-feet identified
in the RFP will come from flow diversion of up
to 3.2cfs from the proposed 60 -inch pipe and the
existing 36 -inch pipe that carry storm flows from
Sierra Highway to the new Mint Canyon Channel.
This storage volume will contribute to a reduction in
the peak flows and total runoff volume downstream
from the Canyon Country Community Center site.
Design of this system will require close coordination
PSOMAS
with Los Angeles County Department of Public
Works, and the City of Santa Claritas consultant
team (Gonzalez Goodale/Michael Baker) that is
designing the Community Center. In selecting
the underground infiltration chmber system, we
will work with the City to evaluate operations and
maintenance issues.
Alternative Alignment
The initial concept exhibits in the RFP suggest the
proposed 60 -inch pipe is located under the planned
community center building. Psomas proposes an
alignment that would move the new pipe to the east
and avoid the planned new building footprint. This
will provide better access for future maintenance
and avoid special bedding and building foundations.
The final storm drain alignments and the infiltration
BMP size and location will be coordinated with the
site architect, Gonzalez Goodale, and site engineer,
Michael Baker Associates, to avoid other prominent
structures or large trees that may interfere with the
long-term operation of the storm drain line.
High Intensity Flow Diversion
The diversion structure at the junction of the
proposed 60 -inch pipe with the existing 36 -inch pipe
will be designed to divert up to 3.2 cfs and allow
for the bypass of larger high intensity storm flows
directly to the Mint Canyon Channel.
Flows diverted to the infiltration BMP from the
Sierra Highway drainage will pass through a pre-
treatment process that will screen out trash and
debris and any other materials larger than 5 mm.
Additionally, we will evaluate design approaches to
provide initial sediment management before the flows
enter the infiltration BMP. This will provide a focused
point for maintenance and help manage the long -
City of Santa Clarita I Canyon Country Community Center
Best Management Practice (BMP) - Regional Stormwater Infiltration System
term maintenance requirements of the main BMP
structure.
There are many pre-treatment options and Psomas
will work with the City of Santa Clarita to develop the
best balance of capital and maintenance costs to meet
the City of Santa Claritas needs.
Dry Weather Flow Diversion
Dry weather flow diversion from the Mint Canyon
Channel will be studied to determine design options
using gravity flow. However, dry weather flow
diversion may require pumping from the channel
bottom to the infiltration BMP. In the area of the
low flow diversion, which is just downstream of
where the covered channel section becomes an open
concrete channel, the Mint Canyon Channel invert is
approximately 15 feet below existing ground, which
may be deeper than the infiltration BMP structure.
Since the dry weather flows are usually small when
compared to an 85th percentile storm event, we
would evaluate the use of a separate infiltration well
specifically for the Mint Canyon drain dry weather
flows. Design of the dry weather flow diversion in
the channel will be closely coordinated with Los
Angeles County so that the structure does not create
adverse effects on the hydraulic capacity and flow
conditions in the channel.

South Los Angeles Wetland Park - Completion of the
Preliminary Design Report (PDR) and Design Services
This is a new purpose-built nine -acre public nature park and sustainable
stormwater treatment wetland constructed on a former MTA Brownfield
re -development site. The treatment facilities include diversion from a major
existing subsurface storm drain, structural pretreatment, high and low flow
pump station, and a 3 -cell, 4.5 -acre treatment wetland. The wetland treats a
portion of the runoff from the contributing 525 -acre watershed and uses that
runoff to sustain the wetland.
Westside Rainwater Park
This purpose-built park diverts stormwater from an existing storm drain
(10 -FT x 11.5 -FT RCB) serving a 3,700 -acre watershed, screens the runoff,
distributes runoff via a new lift station, and provides further treatment via
a subsurface irrigation system. A dry creek and underdrain system collects
excess treated stormwater and returns it to the existing storm drain system.
Mar Vista Recreation Center Stormwater BMP Project
The Mar Vista Recreation Center stormwater BMP project was designed to
divert, treat, detain, and disinfect runoff from a 270 -acre area for reuse as an
irrigation source for the existing park. The project diverts stormwater from the
existing 78 -inch storm drain in Sawtelle Boulevard via a treatment train, which
includes trash removal, hydrodynamic separation, a stormwater diversion and
circulation pump station, an underground 260,000 -gallon detention facility
(constructed under tennis courts), and a chlorination/dechlorination system.
Imperial Highway Stormwater BMP Project - Preliminary Design
Report (PDR) and Design Services in Preparation for Construction
The Imperial Highway project was designed to infiltrate a watershed
area of 7.5 acres. The project includes a vegetated median pre-treatment,
a linear 250 -foot long by 10 -foot wide by 6 -foot deep infiltration basin,
and 1.6 acres of native vegetation planted along the highway median.
This stormwater BMP assists in minimizing the discharge of pollutants,
including oil and grease, suspended solids, and metal to receiving waters.
Westminster Dog Park BMP Project
The Dog Park project captures and treats on-site runoff from the existing Dog
Park prior to being released into the storm drain system. The project includes
runoff' pre-treatment through surface vegetation and a shallow underdrain
system, which provides water to a Modular Constructed Wetland Unit.

The completed design will include an Operations
and Maintenance manual that provides schedules
and timing for inspections as well as processes and
procedures for maintenance operations. Since this
is a "Regional Facility" as identified in the EWMP
it may be a prime choice for inclusion as a test site
for the Coordinated Integrated Monitoring Program
(CIMP). Psomas will discuss this possibility with
the City of Santa Clarita and review possible design
changes to effectuate that testing.
The overall objective of this BMP design is to enable
the City of Santa Clarita to meet the requirements
of the MS4 permit through implementation of
the EWMP program by fully integrating the BMP
into the Canyon Country Community Center
development.

Task 3: Design
The design stage of the project will establish and
verify the design parameters and create a preliminary
design layout that defines the project and serves as the
basis for developing the construction documents for
approval by all required agencies. During this stage,
extensive collaboration is required with the City of
Santa Clarita, County of Los Angeles and the site
development team, Gonzalez Goodale/Michael Baker
to establish location of the infiltration BMP, the new
60 -inch storm drain pipe, and the diversion structures
and pre-treatment devices. Specific activities and
deliverables related to this task are listed below.
3.1 Compile a comprehensive site base plan that
integrates the site survey (by others), community center
site design, and the County Mint Canyon drain project.
3.2 Review drain inverts and community center
grading to establish a vertical relationship between the
storm water system inverts and site design grading.
3.3 Develop and refine the design concept including:
A design concept for the diversion structure at the
junction of the proposed 60 -inch and 36 -inch pipes
PSOMAS
with consideration to the flow rates and hydraulic
function of the diversion.
Create a concept design for the low flow diversion
from the Mint Canyon channel and collaborate with
the Los Angeles County design division to assess
the hydraulic impacts of the diversion on the main
channel HGL.
Develop preliminary design approaches for pre-
treatment including trash, debris, and sediment
removal. Review with the City of Santa Clarita and
discuss overall effectiveness, cost, operation, and
maintenance preferences.
■ Develop preliminary profiles and sections for the
storm drain pipes, diversions, and infiltration
BMP structure. Establish preliminary hydraulic
operations of the system to establish the BMP base
elevation, inlet pipes, and overflow outlet pipes.
Identify if a pump station is required to deliver
low flows from the Mint Canyon Drain to the
infiltration BMP, establish the design flow rates, and
preliminary pump station design requirements.
Identify design alternatives for the Infiltration BMP
structure and prepare an evaluation of each option.
Review these options with the City of Santa Clarita
staff to discuss long-term maintenance preferences.
3.4 Evaluate potential modifications to the Canyon
Country Community Center site design to
accommodate the design and maintenance access for
components of the infiltration BMP system.
3.5 Coordinate with the City of Santa Clarita and
community center design consultants, Gonzalez
Goodale/Michael Baker and collaborate on the
placement of the infiltration BMP design elements
to minimize design impacts to the site. Items to
be considered in this design collaboration include
locations of manholes and access locations for
monitoring, cleaning, and maintenance. Vehicle access
will be required for trucks and equipment used to clean
and maintain pretreatment and infiltration structures.
Depth of cover over the infiltration structure must be
coordinated so that landscaping can be established that
the root structure of trees and other planting material
will not adversely impact the infiltration structure.
3.6 Provide ongoing coordination and design
collaboration through regular review meetings with
the City of Santa Clarita and the Project Development
Team to provide an integrated design solution for the
