required in connection with the performance of services under this Agreement.
14. WAIVER. CITY's review or acceptance of, or payment for, work product prepared by
CONSULTANT under this Agreement will not be construed to operate as a waiver of any rights
CITY may have under this Agreement or of any cause of action arising from CONSULTANT's
performance. A waiver by CITY of any breach of any term, covenant, or condition contained in
this Agreement will not be deemed to be a waiver of any subsequent breach of the same or any
other term, covenant, or condition contained in this Agreement, whether of the same or different
character.
15. TERMINATION.
A. Except as otherwise provided, CITY may terminate this Agreement at any time
with or without cause.
B. CONSULTANT may terminate this Agreement at any time upon thirty days'
written notice.
C. Upon receiving a termination notice, CONSULTANT will immediately cease
performance under this Agreement unless otherwise provided in the termination
notice. Except as otherwise provided in the termination notice, any additional
work performed by CONSULTANT after receiving a termination notice will be
performed at CONSULTANT's own cost; CITY will not be obligated to
compensate CONSULTANT for such work.
D. Should termination occur, all finished or unfinished documents, data, studies,
surveys, drawings, maps, reports and other materials prepared by
CONSULTANT will, at CITY's option, become CITY's property, and
CONSULTANT will receive just and equitable compensation for any work

F. By executing this document, CONSULTANT waives any and all claims for
damages that might otherwise arise from CITY's termination under this Section.
16. OWNERSHIP OF DOCUMENTS. All documents, data, studies, drawings, maps, models,
photographs and reports prepared by CONSULTANT under this Agreement are CITY's
property. CONSULTANT may retain copies of said documents and materials as desired but will
deliver all original materials to CITY upon CITY's written notice. CITY agrees that use of
CONSULTANT's completed work product, for purposes other than identified in this Agreement,
or use of incomplete work product, is at CITY's own risk.
17. PUBLICATION OF DOCUMENTS. Except as necessary for performance of service under
this Agreement, no copies, sketches, or graphs of materials, including graphic art work,
prepared pursuant to this Agreement, will be released by CONSULTANT to any other person or
public CITY without CITY's prior written approval. All press releases, including graphic display
information to be published in newspapers or magazines, will be approved and distributed solely
by CITY, unless otherwise provided by written agreement between the parties.
18. INDEMNIFICATION. This Agreement contemplates that CONSULTANT will act both as a
design professional (as defined by Civil Code § 2782.8) and for other management services.
Accordingly, CONSULTANT agrees to provide indemnification as follows:
A. CONSULTANT must save harmless, indemnify and defend CITY and all its
officers, employees and representatives from and against any and all suits,
actions, or claims, of any character whatever, brought for, or on account of,
any injuries or damages sustained by any person or property arising from,
pertaining to, or relating to the negligence, recklessness, or willful
misconduct of CONSULTANT or any of CONSULTANT's officers, agents,
employees, or representatives. CONSULTANT's duty to defend consists of
reimbursement of defense costs incurred by CITY in direct proportion to the
CONSULTANT's proportionate percentage of fault. CONSULTANT's percentage
of fault will be determined, as applicable, by a court of law, jury or arbitrator. In
the event any loss, liability or damage is incurred by way of settlement or
resolution without a court, jury or arbitrator having made a determination of the
CONSULTANT's percentage of fault, the parties agree to mediation to determine
the CONSULTANT's proportionate percentage of fault for purposes of
determining the amount of indemnity and defense cost reimbursement owed to
the CITY; CONSULTANT and CITY must each pay half the mediator's fees.
Notwithstanding the above, in the event one or more defendants to a Claim is
unable to pay its share of defense costs due to bankruptcy or dissolution of the
business, the CONSULTANT must meet and confer with the CITY regarding
unpaid defense costs.
B. Defense For All Non -Design Professional Liabilities. Notwithstanding the
foregoing and without diminishing any rights of the CITY under subsection A, for
any liability, claim, demand, allegation against CITY arising out of, related to, or
pertaining to any act or omission of CONSULTANT, but which is not a design
professional service, CONSULTANT must defend, indemnify, and hold harmless
Indemnitees from and against any and all damages, costs, expenses (including
reasonable attorneys' fees and expert witness fees), judgments, settlements,
and/or arbitration awards, whether for personal or bodily injury, property damage,
or economic injury, to the extent that they arise out of, pertain to, or relate to the
negligence, recklessness, or willful misconduct of the CONSULTANT.

Agreement No. 6128
C. For purposes of this section "CITY" includes CITY's officers, officials, employees,
agents, representatives, and certified volunteers.
D. It is expressly understood and agreed that the foregoing provisions are intended
to be as broad and inclusive as is permitted by the law of the State of California
and will survive termination of this Agreement.
The insurance coverage to be maintained by CONSULTANT as required by Section 22, will not
limit the liability of CONSULTANT hereunder. The provisions of this section will survive the
expiration or earlier termination of this Agreement.
19. ASSIGNABILITY. This Agreement is for CONSULTANT's professional services.
CONSULTANT's attempts to assign the benefits or burdens of this Agreement without CITY's
written approval are prohibited and will be null and void.
20. INDEPENDENT CONTRACTOR. CITY and CONSULTANT agree that CONSULTANT will
act as an independent contractor and will have control of all work and the manner in which it is
performed. CONSULTANT will be free to contract for similar service to be performed for other
employers while under contract with CITY. CONSULTANT is not an agent or employee of CITY
and is not entitled to participate in any pension plan, insurance, bonus or similar benefits CITY
provides for its employees. Any provision in this Agreement that may appear to give CITY the
right to direct CONSULTANT as to the details of doing the work or to exercise a measure of
control over the work means that CONSULTANT will follow the direction of the CITY as to end
results of the work only.
21. AUDIT OF RECORDS. CONSULTANT will maintain full and accurate records with respect
to all services and matters covered under this Agreement. CITY will have free access at all
reasonable times to such records, and the right to examine and audit the same and to make
transcript therefrom, and to inspect all program data, documents, proceedings and activities.
CONSULTANT will retain such financial and program service records for at least three (3) years
after termination or final payment under this Agreement.
22. INSURANCE.
A. Before commencing performance under this Agreement, and at all other times
this Agreement is effective, CONSULTANT will procure and maintain the
following types of insurance with coverage limits complying, at a minimum, with
the limits set forth below:

B. Commercial general liability insurance will meet or exceed the requirements of
ISO-CGL Form No. CG 00 01 11 85 or 88, or equivalent. The amount of
insurance set forth above will be a combined single limit per occurrence for bodily
injury, personal injury, and property damage for the policy coverage. Liability
policies will be endorsed to name CITY, its officials, and employees as
"additional insureds" under said insurance coverage and to state that such
insurance will be deemed "primary" such that any other insurance that may be
carried by CITY will be excess thereto. CITY's additional insured status will
apply with respect to liability and defense of suits arising out of CONSULTANT's
acts or omissions. Such insurance will be on an "occurrence," not a "claims
made," basis and will not be cancelable or subject to reduction except upon thirty
(30) days prior written notice to CITY.
C. Professional liability coverage will be on an "occurrence basis" if such coverage
is available, or on a "claims made" basis if not available. When coverage is

insurance for a period of three (3) years after this Agreement expires or is
terminated. Such insurance will have the same coverage and limits as the policy
that was in effect during the term of this Agreement and will cover
CONSULTANT for all claims made by CITY arising out of any errors or omissions
of CONSULTANT, or its officers, employees or agents during the time this
Agreement was in effect.
D. Automobile coverage will be written on ISO Business Auto Coverage Form CA
00 01 06 92, including symbol 1 (Any Auto).
E. CONSULTANT will furnish to CITY valid Certificates of Insurance evidencing
maintenance of the insurance required under this Agreement, a copy of an

under the CONSULTANT's General Liability policy, and such other evidence of
insurance or copies of policies as may be reasonably required by CITY from time
to time. Insurance must be placed with insurers with a current A.M. Best
Company Rating equivalent to at least a Rating of "A:VII."
F. Should CONSULTANT, for any reason, fail to obtain and maintain the insurance
required by this Agreement, CITY may obtain such coverage at CONSULTANT's
expense and deduct the cost of such insurance from payments due to
CONSULTANT under this Agreement or terminate pursuant to Section 15.
23. USE OF SUBCONTRACTORS. CONSULTANT must obtain CITY's prior written approval
to use any consultants while performing any portion of this Agreement. Such approval must
approve of the proposed consultant and the terms of compensation.
24. INCIDENTAL TASKS. CONSULTANT will meet with CITY monthly to provide the status on
the project, which will include a schedule update and a short narrative description of progress
during the past month for each major task, a description of the work remaining and a description

PROJECT UNDERSTANDING AND APPROACH
The City owns and maintains a storm drain system within Center Street between Pine Avenue
and Imperial Avenue that conveys runoff from an approximate 230-acre drainage area as
depicted in the exhibit below.

- -=APPROX. DRAINAGE
BOUNDARY
Excerpt from a USGS topographic map with existing storm drain main lines and approximate
tributary drainage boundary superimposed
The storm drain system within Center Street drains to the north to a retention basin along the
northerly side of Imperial Avenue. From the retention basin, the City's Storm Drain Plant No. 17
pumps the runoff to the west through a County -maintained 42-inch storm drain pipe. There are
several branches of the storm drain system that enter the Center Street storm drain from the east
and from the west along its alignment as shown in the exhibit above.
From a cursory review of record plans, it appears that a majority the Center Street Storm Drain
System was constructed in the 1950s and 1960s. The system consists of 30-inch to 84-inch
diameter main lines with 18-inch and 24-inch diameter catch basin connector pipes. The storm
drain main line increases in size from south to north as more tributary storm drain runoff is
collected by the system. City staff has no known available hydrology or hydraulic calculations or
analyses for this system on file.
Along Center Street roughly between Oak Avenue and Sycamore Avenue there is a low point, or
sump, in the roadway and surrounding topography. There are nine (9) drainage inlets in this
approximate 1,000-foot reach of Center Street. Within the sump condition at this location, there

is a concern that this area may be subject to flooding during large storm events and there may be
a potential for flood damage to properties fronting Center Street between Oak Avenue and
Sycamore Avenue, particularly at or near 748 Center Street.
The drainage area tributary to the Center Street Storm Drain encompasses approximately 230
acres (see map on previous page) and this entire drainage area would need to be analyzed to
completely evaluate the potential for flooding along Center Street. However, for the purpose of
this study, an assumption will be made that the hydraulic grade line of the storm drain main line
is not the controlling factor in the street capacity and inlet capacity along Center Street between
Oak Avenue and Sycamore Avenue. A drainage study will be performed for the approximate 18-
acre area tributary to the sump area of Center Street as depicted below in blue.

BOUNDARY
A drainage map will be prepared using the USGS topographic map, Omnis' field reconnaissance,
and other available plans and topographic maps available from the City, to delineate the
approximate tributary drainage boundary to Center Street between Oak Avenue and Sycamore
Avenue. A hydrology study will be prepared in accordance with the Los Angeles County
Department of Public Works (LACDPW) Hydrology Manual for the surface drainage area
tributary to Center Street between Oak Avenue and Sycamore Avenue.
Using the peak flows from the hydrology study, a hydraulic analysis will be performed for the
street capacity of Center Street and the nine (9) catch basins identified in the sump area, roughly
between Oak Avenue and Sycamore Avenue. The hydraulic analysis will include determining
the approximate capacity of the catch basin inlets, catch basin connector pipes, and the
approximate street capacity of Center Street at the sump location. From the hydraulic analysis, a
determination can be made of whether the existing catch basins likely provide adequate flood

protection for the properties fronting Center Street at the sump location. A deficient drainage
system would be identified when the peak runoff is not contained within the street curbs and will
likely exceed the right-of-way and potentially flood private property. If it is determined that there
is likely a drainage deficiency along this reach of Center Street, recommendations will be
provided for catch basin and/or connector pipe improvements to collect and convey the runoff to
the storm drain main line. From these recommendations, Omnis will prepare design plans for the
modification to and/or construction of catch basins and connector pipes to alleviate potential
flooding conditions along the sump area of Center Street.
SCOPE OF SERVICES
Task 1.0 Drainage May
A drainage map will be prepared for the drainage basins tributary to Center Street between Oak
Avenue and Sycamore Avenue using a USGS topographic map and other available record plans
from the City. The existing storm drain system will be added to the drainage map from record
storm plans to identify the drainage inlet locations and sizes. The existing storm drain pipe sizes,
invert elevations, and slopes will be added to the Drainage Map from record storm drain plans.
Task 2.0 Field Reconnaissance
Omnis staff will review the drainage basins tributary to Center Street Oak Avenue and Sycamore
Avenue to confirm catch basin locations and sizes and identify and/or confirm tributary drainage
boundaries to each catch basin.
Task 3.0 Hydrology Study
The Drainage Map will be updated to reflect the findings from our field reconnaissance and
tributary drainage basins will be finalized. Each drainage basin will be evaluated in accordance
with the LACDPW Hydrology Manual and flow rates contributed be each basin will be
determined at points of confluence (typically at a catch basin). Connector pipe flows and street
flows will be determined and tabulated.
Task 4.0 Hydraulic Analyses
Using the peak flow rates from the Hydrology Study, Omnis will perform hydraulic analyses of
the nine (9) existing catch basins in the sump are of Center Street, roughly between Oak Avenue
and Sycamore Avenue. The hydraulic analyses will determine the adequacy of the existing catch
basins, connector pipes, and street capacity for providing the appropriate level of flood
protection to the properties along Center Street at the sump location. If it determined that there
are drainage deficiencies, recommendations will be provided for possible drainage improvements
to resolve any deficiencies at this location. This could include catch basin opening size, catch
basin locations, catch basin connector pipe sizes, and/or additional catch basins.

Task 5.0 Drainage Improvement Plans
Omnis will prepare drainage improvement plans for Center Street between Oak Avenue and
Sycamore Avenue including new catch basins and connector pipes and/or modifications to
existing catch basins and connector pipes to alleviate potential flooding as determined from the
Hydraulic Analysis. The plans will be prepared at a scale of F=40' on standard City titleblock
and will include existing curbs, gutter, driveways, and utilities along with the proposed drainage
improvements and details. A standard City title sheet will also be prepared for the project
including vicinity and location map, sheet index, and appropriate general notes. Technical
specifications, a bid schedule, and a construction cost estimate will also be prepared and
provided to the City with the improvement plans.
