ProjectBackground
About Ballona Creek/Watershed
The Ballona Creek Watershed covers
approximately 130 square miles in the
coastal plain of the Los Angeles Basin. Its
boundaries are the Santa Monica
Mountains to the north, the Harbor
Freeway (110) to the east, and the
Baldwin Hills to the south. The
watershed includes the Cities of Beverly
Hills and West Hollywood, portions of
the Cities of Los Angeles, Culver City,
Inglewood
and
Santa
Monica,
unincorporated areas of Los Angeles
County, and areas under the jurisdiction
of Caltrans.
Ballona Creek flows as an open channel for just under 10 miles from
mid-Los Angeles (south of Hancock Park) through Culver City,
reaching the Pacific Ocean at Playa del Rey (Marina del Rey Harbor).
The Estuary portion (from Centinela Avenue to the outlet) is soft
bottomed, while the remainder of the Creek is lined in concrete.
Ballona Creek is fed by a network of underground storm drains which
reaches north into Beverly Hills and West Hollywood. Major
tributaries of the Creek and Estuary include Centinela Creek,
Sepulveda Channel, and Benedict Canyon Channel.
WhatisaTMDL?
A Total Maximum Daily Load (TMDL) is the maximum amount of a
specific pollutant, such as trash, bacteria, or pesticides that could be
discharged into a waterbody without causing that waterbody to
become impaired. Development of TMDLs, which are driven by the
federal Clean Water Act, is an important step in cleaning up our
creeks, lakes, rivers, and beaches.
Purpose of the Project
In June 2006, the Los Angeles Regional Water Quality Control Board
(Board) adopted a Basin Plan Amendment establishing the Ballona
Creek Bacteria TMDL, which became effective in 2007. The TMDL
was amended in June 2012 and the amendment became effective
on July 2, 2014. To meet this new water quality standard, the Board
granted a Time Schedule Order (TSO) to allow the Permittees (Cities
of Los Angeles, Beverly Hills, Culver City, Inglewood, and West
Hollywood; County of Los Angeles; County Flood Control District) to
devise an approach to reduce bacteria in Ballona Creek during dry
weather. Compliance with the TSO is required by December 2019.

As the lead agency of the Project, LA Sanitation of the City of Los
Angeles has performed flow/treatment modeling to determine the
technical specifications that the facilities will require to achieve
TMDL compliance. From this effort, LA Sanitation and the other
Permittees have designed three water quality treatment/diversion
facilities, which comprise the Project. These proposed
developments are discussed in detail at the next stations.

AboutTheProposedProject
ProjectOverview
Objectives
After consideration of several options, the Permittees are proposing a three-pronged
approach to effectively reduce bacteria in Ballona Creek and its major tributaries. All
proposed facilities are located on properties where existing water quality facilities are
in place. The proposed Project involves developing the following three facilities:
ThePermitteesproposetomeettheTSOdeadline
andaddressBacteriaTMDLcomplianceinaway
thatwilleffectively:
1) Treat-and-release 6 million gallons per day (MGD) flow in Ballona Creek at an
upgraded Low Flow Treatment Facility 1 and divert up to 23 MGD to the
Hyperion Water Reclamation Plant (Hyperion WRP) for treatment and potential
beneficial reuse.
2) Treat-and-release up to 1.3 MGD flow in Sepulveda Channel at a new Low Flow
Treatment Facility 2.
3) Convert the existing Mesmer pump station to a Low Flow Diversion structure to
divert up to 0.97 MGD of Centinela Creek flow to Hyperion WRP for treatment
and potential beneficial reuse.

TheCEQA/EIRProcess
Overview of CEQA Process
The CEQA environmental review process will be conducted for the Project with LA Sanitation preparing an Environmental Impact Report (EIR). The
EIR will evaluate the potential impacts that the Project and Alternatives may have on people or the environment and addresses issues such as, air
quality, biology, hydrology, noise, and construction impacts, among others. As provided in the timeline below, the public will have the opportunity
to comment on the project and the environmental review during the public involvement processes and release of the Draft EIR (anticipated in July
2017).

As part of the Department of Public
Works, LA Sanitation oversees the City of
Los Angeles' Clean Water, Solid
Resources and Watershed Protection
programs.
Through LA Sanitation’s efforts, Los
Angeles has been at the forefront of
environmental stewardship, from the
restoration of Santa Monica Bay, to
achieving one of the highest trash
recycling rates among large cities in the
nation, to the implementation of the Low
Impact Development (LID) Ordinance for
stormwater capture and infiltration.
On behalf on the Permittees, LA
Sanitatiom will serve as the CEQA
Responsible
Agency.
Being
the
Responsible Agency means LA Sanitation
takes the lead on preparing the EIR,
conducting public involvement, and
consulting with other federal and state
agencies.

LevelsofSignificance
PerCEQAguidance,thefollowingpointsdefinethevariouslevelsof
“significance”indescribinganeffect:
• Beneficial Effect - The Project would result in an overall improvement to the
existing baseline condition.
• No Impact - The Project will not have any measurable environmental impact
on the environment.
• Less Than Significant Impact - The Project may have the potential for
affecting the environment, although these impacts will be below levels or
thresholds that the City of Los Angeles or other responsible agencies
consider to be significant.
• Less Than Significant Impact with Mitigation - The Project may have the
potential to generate impacts that will have a significant impact on the
environment. However, the level of impact may be reduced to levels that are
less than significant with the implementation of mitigation measures.
• Potentially Significant Impact - The Project may result in environmental
impacts that are significant and cannot be reduced to levels that are less
than significant even with the implementation of mitigation measures.
WhenMitigationIsApplied
If an impact is determined to be potentially significant,
an Agency/Department may assign mitigation measures
to abate the intensity of the effect. Mitigation, for
example, can be a Project design feature, operating
procedure, and/or resource monitoring. Mitigation is
intended to reduce the intensity of the impact to “less
than significant” (LTS) and can be included as a
condition of permit issuance.

TipsforWritinganEffectiveComment
Public comments play a critical role in the CEQA process. By providing
comments, Agencies and the Public help frame the Alternatives and
issues for analysis in the EIR.
The CEQA process benefits from the Public providing substantive
comments that focus on the design/layout of the proposed Project
facilities, Alternatives to the Project, and the environmental, social, and
public resources potentially impacted by the Project.
The following points summarize the guidance provided by the federal
Council of Environmental Quality (CEQ) on writing an effective comment:
• Comments should be clear, concise, and relevant to the analysis of the
Proposed Action.
• Comments that are solution-oriented and provide specific examples
are more effective than those that simply oppose the proposed
Project.
• Comments that contribute to the development of Alternatives that
address the Purpose and Need are most effective early in the
NEPA/CEQA process (i.e. during scoping).
• When writing comments, focus on the Purpose and Need, proposed
Project, Alternatives to the Project, the assessment of environmental
impacts of those Alternatives, and potential mitigation measures.
• Commenting is not a form of “voting” on an Alternative. The number
of negative comments received does not prevent an action from
moving forward. Numerous comments that repeat the same basic
message of support or opposition will typically be responded to
collectively.
• General comments that state an action will have “significant
environmental effects” will not help an agency make a better decision
unless the relevant causes and effects are explained and technically
supported.
