BACKGROUND AND DISCUSSION:
In 2012, the Los Angeles Regional Water Quality Control Board issued the fourth
Municipal Separate Storm Sewer System (MS4) Stormwater Permit to all of the cities in
Los Angeles County, including Rancho Palos Verdes. This permit requires cities to
implement measures to meet rigorous limits regarding the quality of stormwater runoff
leaving their jurisdictions. Estimated costs to implement these measures have been as
high as $20 billion countywide. In 2012, there was no funding source that remotely
approached close to providing that level of funding. The lack of funding to construct
required stormwater treatment systems would result in all cities violating the permit.
1
Because of this lack of funding, the Los Angeles County Department of Public Works
looked for ways to bridge this issue by introducing Measure W. This parcel tax measure
was placed on the countywide ballot in November 2018 to provide funding for the
capture and treatment of stormwater runoff, which would improve stormwater quality.
Measure W was introduced as a tax rather than a fee, exempting schools and
municipally-owned properties. Measure W was approved by more than two-thirds of
voters and is now referred to as the Safe Clean Water (SCW) Program. Countywide, the
measure is expected to generate between $265 million to $285 million annually with the
following breakdown appropriations:
50% for large-scale regional projects
40% to the cities for local water quality/supply improvement projects and program
implementation
10% for county administration of the SCW Program.
Regional Project
In August 2019, the Los Angeles County Board of Supervisors adopted the
implementation ordinance for Measure W , but the ordinance itself is very general and
directs county staff to further develop detailed implementation procedures. Rules and
regulations have not yet been fully finalized.
One such regional project is the Torrance Airport Stormwater Infiltration Project
(Attachment A). This project addresses the Machado Lake TMDLs (Total Maximum
Daily Loads) of nutrients, toxics and pesticides. On December 19, 2017, the City, along
with the other Peninsula Cities (known as the Peninsula Watershed Management Group
(WMG), entered into a Memorandum of Agreement (Attachment B) with the City of
Torrance for preliminary design for the Torrance Airport project. The City of Torrance
used Proposition 1 grant money, with matching funds from the Peninsula WMG and
unincorporated Los Angeles County to fund this Preliminary Design Report. The total
matching funds from all agencies was $238,336, which was divided proportionally
based on each agency’s drainage shed area. The City of the RPV contributed $41,092
for the Preliminary Design Report which consists of an underground deep injection
infiltration system. However, the Peninsula WMG later learned that this project held a
risk associated with existing underground contamination. Currently, the City of Torrance
is in the process of developing a revised design for the project and the participating
agencies will be reviewing the revised report to re-evaluate this project and make a
determination as to whether or not to proceed with this project. At this time, the City of
RPV is still considering this project to be viable solution to the water quality
requirements, but is exploring alternative projects in the event the City decides to
withdraw from the Torrance project.
To that end, aside from Torrance Airport Project, there is another potential project that is
needed to address the Harbor Toxics TMDL. This project could potentially be located at
the Eastview Park. The project would encompass 350 acres of drainage area, and help
achieve compliance with the regional watershed target goals. The proposal to perform a
2
feasibility study for the Eastview Park project was submitted to the South Santa Monica
Bay Watershed Area Steering Committee (SSMB WASC) as a placeholder subject to
City Council approval. The estimated cost of this feasibility study is $300,000 and it will
be funded by Measure W as part of a large scale regional project. The Peninsula WMG
has expressed an interest in this potential project. The funding of this feasibility study
will not impact our local share of $690,000 per year. It is noted that the Eastview Park is
owned by the Los Angeles County Sanitation Districts and the City is leasing this
property. The Los Angeles County Flood Control District would be the project manager.
Staff recommends the City Council direct Staff to proceed with the preparing a feasibility
study for consideration of this regional stormwater capture and infiltration system at
Eastview Park.
Local Project
For local projects, the City of RPV’s is estimated to receive approximately $690,000 per
year. These funds could be used for such projects as the Hawthorne Blvd. Median
Landscape Project (which contains a swale within the median) or Portuguese Bend
Landslide Remediation Project (where a detention basin is proposed), because
implementation of these projects would result in improved storm water runoff quality.
Based on past Council discussions, Staff recommends pursuing Measure W local
project funds as a funding source for the Portuguese Bend Landslide Remediation
Project. According to John L. Hunter and Associates’ preliminary analysis of Measure
W indicates that the Portuguese Bend Landslide Remediation Project is eligible for
funding. Staff intends to apply for funding before the deadline of July 31, 2020.
CONCLUSION:
The City’s water quality consultant, John L. Hunter and Associates has prepared a brief
presentation regarding the Measure W program as it pertains to Rancho Palos Verdes,
which will be presented to the City Council at its March 17 meeting. John L. Hunter and
Associates will also discuss the eligibility of the Portuguese Bend Landslide
Remediation Project.

A. Staff Report from March 1, 2016, City Council meeting (page A-1)
BACKGROUND AND DISCUSSION:
The authorization to proceed with a Memorandum of Understanding (MOU) with the City
of Torrance will allow the City the opportunity to participate in the preliminary design of a
storm water treatment and infiltration project at Torrance Airport.
The City has obligations under the Municipal Separate Storm Sewer System (MS4)
Permit (Permit) to reduce or prevent runoff -borne pollution in the City’s drainage system
from entering its three receiving waters: the ocean (Santa Monica Bay), Los Angeles
Harbor and Machado Lake, located in the Harbor City area of the City of Los Angeles.
The Peninsula Watershed Management Group (Peninsula WMG)1 previously identified
non-structural control measures and structural (construction) projects to accomplish the

and Rolling Hills Estates, and the County of Los Angeles. The City of Rolling Hills has limited

goals of the MS4 (Stormwater) Permit. The Enhanced Watershed Management
Program (EWMP) was developed and submitted to the Regional Water Quality Control
Board (Regional Board) in June 2015. The Regional Board approved the final EWMP
document on April 19, 2016, and the City Council adopted the EWMP on June 21, 2016.
During the preparation of the draft EWMP, the Peninsula WMG (which is chaired by the
City of Rancho Palos Verdes) learned of a project that the City of Torrance is pursuing
to meet their MS4 requirements for Machado Lake. This project, if modified to
accommodate flows from the Peninsula WMG, can eliminate the need to build two other
EWMP projects (Palos Verdes Landfill Subsurface Wetland and Valmonte Subsurface
Wetland, at the estimated combined cost of $127 million). These two projects had a
presumed City share of the total estimated cost of $33 million. By effectively reducing
the Peninsula WMG’s pollutants from entering Machado Lake, an upsized Torrance
project has the potential to meet the MS4 requirements for the City’s portion of the
Machado Lake watershed. Thus, the City’s obligation for structural solutions for
Machado Lake under the current MS4 Permit may be satisfied.
The Torrance project was detailed in a presentation to the City Council on March 1,
2016. Partnering in the Torrance Airport project could reduce the estimated cost burden
of the City by a factor of five or more (reducing it from $33 million to $6.71 million), and
greatly increase the chances of meeting the Regional Board’s 2018 compliance
deadlines, thereby avoiding the potential for fines. At the direction of the City Council,
the City issued a letter of commitment to the City of Torrance for the Torrance Airport
Project.
During the preliminary investigation of the Torrance Airport project, the City of Torrance
notified the Peninsula WMG that there was an existing groundwater contamination
plume around the airport. Subsequently, an existing contamination plume was
discovered. Further, it was determined that if the potential Torrance Airport Project
caused any movement of the plume, the stakeholders would be held as legally
responsible parties. In light of this discovery, the Peninsula WMG sent a letter to the
City of Torrance on February 2017 stating that it would not participate in the project.
After several attempts, the City of Torrance was able to reconfigure the project so that it
would not affect the existing contamination plume and remove potential legal issues
with the potential stakeholders. On November 27, 2017, the Peninsula WMG met with
the City of Torrance to review the revised concept and preliminary cost share. The
project was approved by the Regional Board and a grant to help finance the project was
obtained by the City of Torrance.
Based on the preliminary numbers, and with the participation of all of the agencies
affected by this project, the cost share for the preliminary design of the Torrance Airport
Project for the City of Rancho Palos Verdes is approximately $35,000. In addition to the
$35,000 cost for this project, Staff is requesting a $15,000 contingency to accommodate
the City’s share of unforeseen preliminary design problems, so the total amount of this
request is up to $50,000. The $35,000 City share is based upon the area that each
A-2
Peninsula WMG agency drains into Machado Lake. The City of Rolling Hills has not
decided whether or not to join this effort, so if they do eventually participate, the City’s
cost will be reduced. Final cost for full design will not be known until the grant award
numbers are determined in detail and the preliminary plans are completed. Looking
beyond the design phase, the estimated construction cost of the project is currently
about $38 million. If all of the Peninsula agencies participated with Torrance, the City’s
share would be about 17%, or roughly $6.5 million, less any grant funding. If the City of
Rolling Hills does not participate, the City’s portion will be 21%, or roughly $7.9 million.
The Peninsula WMG met with the Regional Board on November 16, 2017, to discuss
the Regional Board’s accelerated schedule and requirements. The Board recognized
that the MS4 compliance schedule and requirements may cause a hardship for the
Water Management Group and would be willing to allow the Group to produce a Time
Schedule Order (TSO) that would grant the Group a 5 -year extension to implement the
requirements. The TSO would detail specific items to be done by the Group to comply.
One of those items is to continue to explore other options and project s.
One alternative that was raised, in previous meetings with the Peninsula WMG, was the
Machado Lake Rehabilitation Project. The construction of this project, which included
dredging most of the lake to a depth of 6 feet and backfilling with clean soils, is 95%
complete and is being administered by the City of Los Angeles. On November 30,
2017, the WMG met with the City of Los Angeles to gauge its receptivity to our City’s
participation in the project. The City of Los Angeles did not have specific cost numbers,
but they stated that their computer models did include the runoff contributed by the
Peninsula WMG’s jurisdiction, and that they will provide these numbers within two
months. Once we have these numbers, the Group can review and confirm a rough
cost-share number for each individual City.
Due to the uncertainty of this option, the Peninsula WMG’s preference is to continue
with the preliminary design of the Torrance Airport Project. The City of Torrance is
asking for a decision by the middle of January 2018. The City’s participation in the
Machado Lake Rehabilitation Project will be kept open as an option, but cannot be
considered at this time until the Group reviews more definite numbers.
Upon approval of Staff’s recommendation, and when approvals by the other Peninsula
WMG jurisdictions are received and cost-sharing amounts are more certain, the MOU
will be prepared and, upon approval of the document as to form by the City Attorney, be
executed by the Mayor.

B. Sample Letter of Support (page B-1)
EXECUTIVE SUMMARY:
Staff has identified an opportunity to partner with the City of Torrance and other
Peninsula agencies to develop a superior stormwater quality project to satisfy the City’s
MS4 Permit obligations. The City of Torrance would take the lead in applying for State
grant funding to develop a stormwater quality project at Torrance Airport, and it seeks a
letter of supports from the City for this application to be submitted to the State this
Friday, March 4, 2016.
BACKGROUND AND DISCUSSION:
The City has obligations under the Municipal Separate Storm Sewer System (MS4)
Permit (Permit) to reduce or prevent runoff-borne pollution in the City’s drainage system
from entering its three receiving waters: the ocean (Santa Monica Bay), Los Angeles
Harbor and Machado Lake, located in the Harbor City neighborhood of the City of Los
A-4
Angeles. Of these, the obligation to Machado Lake is the most costly and most urgent.
Non-structural control measures and structural (construction) projects to accomplish this
were identified previously by the Peninsula Watershed Management Group (Peninsula
WMG) in the draft Enhanced Watershed Management Program (EWMP), and submitted
to the Regional Water Quality Control Board (Regional Board) in June 2015. The
Council authorized Staff to submit the draft EWMP that was presented at the June 16,
2015, City Council meeting (Attachment A). The draft EWMP is now under review by
the Regional Board with approval expected later this spring, at which time it will be
brought back to City Council for adoption.
Water from the north side of the Peninsula travels through Peninsula-agency storm
drains, then through City of Torrance drains before it discharges into Machado Lake.
The draft EWMP identified two projects on the Peninsula – the Palos Verdes Landfill
Subsurface Wetland and the Valmonte Subsurface Wetland (see Table 1 below) – that
would serve to achieve Permit compliance by treatment of the runoff destined for
Machado Lake before leaving the Peninsula.
Table 1 – EWMP-Identified Potential Projects
Proposed Project Range of Capital
Cost
RPV
Tributary
Area
Presumed RPV Share

Palos Verdes Landfill
Subsurface Wetland $57.8M to $86.4M 38% $22M to $33M
Valmonte Subsurface
Wetland $19.4M to $26.5M 24% $4.7M to $6.4M
TOTAL $77.2M to $112.9M $26.7M to $39.4M
There are very low tolerances for pollutants entering the lake, so the treatment facilities
would need to be sophisticated and costly. While not ideal, they are the best of several
bad options available for projects sited on the Peninsula. The combined capital cost
range for these two projects is estimated at $77M to $113M, not counting operations
and maintenance costs. The City’s fair share would range from $26.7M to $39.4M
(midpoint is $33M) if cost sharing is calculated based on tributary area, which is
common. Furthermore, the projects will need to be completed by September 2018 for
compliance with strict MS4 deadlines, which would be unlikely given their complexity.
The significant new costs projected by the EWMP have been discussed at meetings of
the Water Quality Flood Protection Oversight Committee and the Infrastructure
Management Advisory Committee, who have both expressed the need to develop
funding sources for stormwater quality projects. In addition, the Los Angeles County
Division of the League of California Cities’ City Managers Group published a report in
June 2014 identifying the magnitude of and reasons for the significant and staggering
Permit compliance costs for many cities (the report is posted on the City’s website at
http://www.rpvca.gov/DocumentCenter/Home/View/1325). The strategies identified
A-5
include pursuit of partnerships on regional projects and seeking grant funding from the
State and other sources (pg. 56 and elsewhere).
Since the writing of the draft EWMP, the Peninsula WMG (which is chaired by the City)
has learned of a project that the City of Torrance is pursuing to meet their MS4
requirements for Machado Lake. This project, if modified to accommodate flows from
the Peninsula, can eliminate the need to build the other two EWMP projects described
above. By effectively preventing the Peninsula’s pollutants from entering the lake, an
upsized Torrance project would meet the MS4 requirements for the City’s portion of the
Machado Lake watershed. Thus, the City’s obligation for structural solutions for
Machado Lake (Public Works construction) under the current Permit would be satisfied.
The Torrance project is much more cost-effective than the two EWMP projects because
it is based on a less-expensive technology (infiltration vs. treatment). Projects relying
on detention and infiltration were rejected in development of the Peninsula’s EWMP
because of limited availability of large lands areas needed for detention and because
the geologic conditions of the Peninsula do not often favor infiltration. Because no
infiltration locations on the Peninsula could be found for this watershed, the two
treatment wetlands projects were put forward as best alternatives. However, the
location of the stormwater infiltration project at the Torrance Airport, where pipes from
the Peninsula converge and where flow from the Peninsula can be conveniently
captured, detained and infiltrated before it enters Machado Lake, enables the City to
participate in this more economical route. Additionally, infiltrated water would recharge
groundwater for some future beneficial use. Furthermore, since the project has already
developed some momentum from Torrance’s preliminary planning efforts, it is much
more likely than the two EWMP projects to be completed prior to the 2018 Permit
compliance deadline.
Torrance is seeking a competitive State grant to support its design effort for the project
and welcomes our partnership. Multiple-benefit and multiple-agency projects make the
grant application much more attractive for award, thus increasing the project’s chances
for outside funding. By participating, the City stands to benefit by drastically reducing
the anticipated capital cost to comply with the Permit requirements for Machado Lake.
The Torrance project’s design effort is expected to cost around $1M and the grant
amount requested is $500,000. The remainder of funding for design would be shared
among the participating agencies, based on their tributary area contributing runoff to the
project. Final cost for design will not be known until the grant award is determined, a
design consultant is selected by Torrance, and a memorandum of understanding (MOU)
between cooperating agencies is finalized. Looking beyond the design phase, the
estimated cost to design and build the project, including the capacity to capture runoff
from the Peninsula, is currently about $14.5M. Although this number is very preliminary
and will adjust as the design and construction bidding are completed, it is clear that the
project will be much preferable financially as compared to the two EWMP projects.
The City also stands to reduce its cost of compliance by cost-sharing the project with
A-6
other agencies. If all of the Peninsula agencies participated with Torrance, the City’s
share would be about 17%, less any grant funding. If only Torrance and RPV
participate, the City’s share would be about 46%. The City’s share of a final project
could be reduced from about a third for the EWMP projects to as little as 17%, and
perhaps less if grant funding is obtained for the Torrance project.
Table 2 presents a worst-case scenario (Torrance and RPV only) sharing of project
costs for the Torrance Airport project. In this scenario, the City’s capital outlay for the
project (and full compliance in the Machado Lake watershed) is estimated at $6.71M.
That still compares favorably (by a factor of 5) to the $33M estimated as the City’s share
of the two EMWP projects. Staff would likely recommend that the City partner with
Torrance for this project, whether or not a grant is received and whether or not the other
Peninsula agencies participate, based upon these costs savings alone.

TOTAL 100% $1M $10M $3.5M $14.5M
Torrance has requested a letter of support for the grant application, and Staff has
prepared the attached draft letter for the City Council’s consideration. The letter states
that if the grant is received, the City would enter into an MOU to share in the cost of
design. If the design cost is reduced to $500,000 by award of the full grant request and
if no other agencies participate, the City’s design cost share obligation would be about
$231,500 (46.3% of $500,000). However, it is likely that other Peninsula agencies will
participate in design and bring the City’s obligation down further, perhaps to as little as
$85,000 (17% of $500,000).
City Council is invited to modify the draft letter as desired, but the Torrance is required
to submit the application by this Friday, March 4, 2016. The City Council would have
the opportunity for further input into the process when the MOU is brought back for
approval, and again prior to continuing into the construction phase.
CONCLUSION
The City has an enormous financial burden under the requirements of the MS4 Permit
to protect Machado Lake against pollutants found in the City’s urban runoff. Partnering
in the Torrance Airport project could reduce that estimated burden by a factor of five or
more (reducing it from $33M to $6.71M), and greatly increase the chances to meet the
Regional Board’s 2018 compliance deadlines, avoiding the potential for fines and
A-7
penalties. A letter of support committing the City to a fair-share of the cost to design the
project will increase the chances for successful grant funding and provide access to
partnership on a project that would be superior to the two that can be built on the
Peninsula.

RECOMMENDATION
Authorize Staff to submit the Draft Enhanced Watershed Management Program to the
Los Angeles Regional Water Quality Control Board on behalf of the Peninsula Water
Management Group in accordance with the permit compliance schedule.
EXECUTIVE SUMMARY
The latest Municipal Separate Storm Sewer System (MS4) Permit (Permit), which
addresses urban runoff and storm water quality, was adopted by the Los Angeles
Regional Water Quality Control Board (Regional Board) on November 8, 2012. The
Permit outlines three means of compliance, with the most robust protections afforded to
permittees that adopt a so-called Enhanced Watershed Management Program (EWMP).
In 2013 the City Council agreed to join other agencies having stormwater jurisdiction on
the Palos Verdes Peninsula to develop an EWMP. The agencies are known as the
Peninsula Watershed Management Group (Peninsula WMG). The City of Rancho Palos
Verdes serves as the administrative lead for Peninsula WMG and is required by Permit
regulations to submit EWMP plan documents on or prior to June 29, 2015 to remain in
compliance. The group has met and worked collaboratively to prepare these documents
with the assistance of technical experts hired through a Memorandum of Understanding
(MOU) between the Peninsula WMG members, which was entered into for this cost-
sharing purpose. The EWMP outlines activities that the City and other agencies of the
Peninsula WMG will need to undertake, including general schedules and estimates of
cost, both of which present challenges. The documents are being made ready for
submittal by the deadline on June 28, 2015. The documents to be submitted, subject to
a few minor changes, are available for review on the City's website at
http://www.rpvca .gov/347/Stormwater-Quality-Program.

Authorization to Submit Draft Enhanced Watershed Management Program
June 16, 2015
Page 2 of 6
The City Council has previously agreed to participate in the Peninsula WMG and has
authorized the development of the group's draft EWMP. At this time, staff intends to
update the Council on the group's progress and simply seeks authorization to submit the
draft EWMP to the Regional Board by the June 28th deadline.
BACKGROUND
The Permit gives cities and agencies three pathways towards compliance: (1) compliance
with the baseline Permit and its numeric water quality standards; (2) development and
implementation of a watershed management program; and (3) development and
implementation of an EWMP, which was selected by the Peninsula WMG. The EWMP
option provides additional compliance coverage (i.e., protection against liability under the
Clean Water Act) for the Permit's water quality standards so long as permittees effectively
develop and implement an EWMP. The EWMP is a comprehensive assessment of the
conditions of the watersheds that the City collects water from and the receiving water
bodies to which it discharges. A detailed analysis of steps necessary to achieve pollution
reduction goals, including identifying specific and effective treatment systems, is based
on that assessment and analysis. The approach required by the Permit is much more
complex than previous permit terms. It is has also been expected that costs for
development and construction of the specific treatment systems will be an order of
magnitude in cost higher than what agencies across LA County have been used to
spending on water quality issues. For that reason, there have been several collaborative,
yet still incomplete, efforts to develop funding sources for these programs. These include
efforts by the County Flood Control District and the Los Angeles County Division of the
California Contract Cities Association.
Staff has presented information on the new Permit requirements to the City Council on
several occasions. These presentations have outlined the evolution of the City's
response to the Permit requirements as Staff has worked to determine the most
advantageous path forward. At its June 18, 2013 meeting, the City Council authorized
Staff to notify the Los Angeles Regional Water Quality Control Board (Regional Board)
that the City would follow the EWMP approach in conjunction with the Peninsula WMG.
A Notice of Intent was filed on June 27, 2013 with the Regional Board to signal this
approach. The Regional Board approved the Notice of Intent.
On August 6, 2013, the City Council approved a Memorandum of Understanding between
the Peninsula WMG agencies in order to begin collaborative work on the EWMP for the
new Permit requirements. Because it is the largest agency by area within the group, the
City of Rancho Palos Verdes serves as the administrative lead. On October 1, 2013, the
City Council awarded a contract to John L. Hunter & Associates to begin work on the
EWMP documents.
On June 17, 2014 the City Council directed staff to submit an EWMP Work Plan on behalf
of the Peninsula WMG. The EWMP Work Plan outlined the technical process and
methods to be followed to develop the EWMP itself.
On two occasions (May 8, 2014 and May 6, 2015) the Peninsula WMG hosted public
2

workshops to encourage stakeholder input on the process, intent, findings and
conclusions of the EMWP. Stakeholders invited included City Council, Water Quality and
Flood Protection Oversight Committee members, other governmental organization staff
and officials, non-governmental organization staff, environmental organizations,
community organizations and Peninsula residents. A member of the RPV City Council
was present at each of these workshops along with staff from other Peninsula WMG
agencies and other stakeholders (South Coast Botanic Garden, Palos Verdes Peninsula
Land Conservancy, Cal Water, residents, etc.). A full list of invited stakeholders,
excerpted from the EWMP document is included as Attachment A In addition, three
separate meetings were held with specific stakeholders who asked to have additional
input.
Two of the City's citizen committees (Water Quality and Flood Protection Oversight
Committee and Infrastructure Management Advisory Committee) have also received
briefings on the requirements of the Permit and the potential impacts to the City's
operations and budgets.
City staff posted the draft EWMP documents on the City's website on May 21, 2015 and
provided notice of their availability in the weekly administrative reports on June 3rd and
June 101h. A list serve message was also distributed on June 3rd for those subscribed the
Storm Water Quality category.
DISCUSSION
Permit Requirements. The purpose of the EWMP is to achieve compliance with the
Permit through identification of pollutants of concern in receiving water bodies, quantifying
the pollution contributed in runoff from the Peninsula watersheds and developing
watershed control measures to reduce or eliminate those contributions. Certain control
measures must be undertaken by all jurisdictions and these are described in the Permit
as Minimum Control Measures (MCMs). These measures are primarily non-structural in
nature and are a continuation or enhancement of the specific measures the City is already
undertaking. However, there are some significant additions to this list. The City must
now address non-stormwater runoff more vigorously, including monitoring and potentially
source tracking of dry weather flows at the City's storm drain outfalls, and a program to
reduce runoff attributable to irrigation overspray. The City must also implement some
standard structural control measures, including adoption of a Low Impact Development
ordinance (which the City Council adopted on April 21, 2015) and a commitment to
installation of full capture screens in catch basins not previously requiring a retrofit. While
these MCMs require an increase in effort compared to what the City already does, the
real impact to the budget will be on the Targeted Control Measures (TCMs). Lists of the
new and enhanced non-structural MCMs and non-structural TCMs proposed are included
in Attachment B.
As the name implies, TCMs are pollutant control measures that address specific
pollutants in specific watersheds. Some of these pollutant I watershed pairings have
County-wide prescribed programs (known as TMDLs) to which the City is already
committed. The Permit also requires the MS4 operators to identify non-structural and
structural measures that will address all remaining predicted pollutant exceedances.

These pollutant predictions, and the prescribed methods to control them are detailed by
a computer modeling effort known as a Reasonable Assurance Analysis (RAA). The RAA
mathematically tests the sufficiency of a proposed treatment system to reduce the
pollutant of concern in the receiving water body. Each watershed group was required to
adopt an RAA as part of the process of developing an EWMP.
RAA Findings. The RAA takes into account anticipated pollution reduction across all
watersheds for non-structural elements of the EMWP. It also takes into account
anticipated reductions from regional projects already underway. In the case of the
Peninsula watershed, these efforts did not produce enough of a reduction to avoid the
need for more structural projects. RAA modelers proposed several technologically
appropriate projects to meet the remaining demand for pollutant reduction. These were
sited where stormwater might be treated most effectively before leaving the Peninsula
watersheds. Of the three catchments in which Peninsula drainage flows, the Machado
Lake watershed presents the biggest challenge to the Peninsula WMG. Because of
limited real estate for treatment, geologic hazards that preclude infiltration options, and
an extremely low tolerance for nutrients (primarily phosphorous) in Machado Lake,
treatment solutions are limited and expensive. Two projects were identified in the RAA,
at the Palos Verdes Landfill and at the Valmonte Canyon, respectively, that provide
sufficient treatment. A smaller, but still significant issue exists in the watershed draining
to the LA Harbor, and the RAA has identified a potential project at Eastview Park to
sufficiently reduce pollutants. Fortunately, the Peninsula's contribution to pollution in the
Santa Monica Bay is or can be managed by current programs or retrofitting catch basins
with trash screens, so no major capital projects are required in this watershed. A map
showing the location of the projects considered by the RAA followed by a summary table
of those projects, excerpted from the EWMP, is included as Attachment C.
Cost and Schedule Implications. The cost to implement these capital projects is difficult
to estimate at this time. Rough costs for construction, permitting, engineering and project
management can all be extrapolated from industry data. Further work would need to be
done to determine the regulatory and political feasibility of these projects. In addition,
land acquisition, legal process and financing efforts are too vague to estimate at this time.
Furthermore, while the projects would be built in only one jurisdiction, they benefit others
so costs should be shared. Details of cost allocations among the Peninsula agencies
would have to be worked out, but they are typically founded on tributary area. Table 1,
below, summarizes data from the EWMP regarding cost, schedule and tributary area for
the three identified projects discussed.

Infiltration Basin $16.6 M
Palos Verdes Landfill $57.8M to $0.86M to $1.0M 38% 2018
Subsurface Wetland $86.4M
Valmonte Subsurface $19.4M to $0.29M to $0.32M 24% 2018
Wetland $26.SM
Table 1 also includes the final water quality compliance deadlines for these projects.
Some of the watersheds have more urgent timelines than others. The Machado Lake
watershed has a significant deadline in 2018. The LA Harbor watershed project could
conceivably be pushed out to the early 2030's. Despite the Permit deadlines, there is
also considerable uncertainty in the schedule, as legal challenges, new watershed
information and funding mechanisms come to light. The Permit's interim and final
compliance milestones for the various pollutant I waterbody combinations are shown in
Attachment D, excerpted from the EWMP.
Using the assumption that the costs would be allocated purely on tributary area, which
may or may not be what is decided, the City's share for these projects could range
between $49 million and $56 million to build over the next two decades and more than
$580,000 per year to operate and maintain once they are built. But the uncertainties with
these figures are as significant as the projected costs themselves and no conclusion
should be drawn other than this: a large financial outlay, likely in the tens of millions of
dollars over the next two decades, will be needed to implement the plans outlined in the
EWMP.
Adaptive Management. These proposed pollution control measures are based on
modeling estimates for pollution levels, assumed treatment system performance and very
limited field data to calibrate the results. The Coordinated Integrated Monitoring Program
(GIMP), formerly approved by Council and currently under review by the Regional Board,
will function as a data collection program and is also a part of the City's Permit response.
The GIMP will begin implementation later in 2015. Additionally, progress toward the water
quality objectives, reconsideration of the water quality standards by the regulatory
agencies, and other new information, may justify new or modified pollution control
measures. The data gathered over the next few years and the further studies into
appropriate treatment solutions that will continue after the EMWP is submitted will
contribute to a fine tuning process known as Adaptive Management. Through Adaptive
Management, the City will periodically adjust its programs to respond to the availability of
new information and actual pollutant measurements observed over time.

CONCLUSION
The City has committed itself to the EWMP process, including a GIMP, by earlier City
Council action in accordance with Staff's recommendations. The draft EWMP identifies
MCMs and TCMs that the City will need to implement in the near future to remain in
compliance with the Permit. Despite likely and significant cost increases to the City and
challenging schedule milestones, the City has committed to the EWMP process. Some
modifications to the control measures listed in the draft document will likely occur due to
review by the Regional Board and through the Adaptive Management process as better
data become available. In any case, the City will be required to significantly increase its
level of effort to remain in compliance with the increasingly complex demands of the
newest MS4 Permit. The Permit compliance schedule requires that agencies committed
to the EWMP method of compliance submit their draft document for review by June 29,
2015. Therefore, Staff recommends that City Council provide authorization to submit the
posted draft EWMP, subject to minor technical and editorial changes, in accordance with
the Regional Board's deadline.
ENVIRONMENTAL ASSESSMENT
The EWMP is a planning document that must be reviewed and approved by the Regional
Board, and any implementing projects and actions would proceed only after Regional
Board approval is granted. Therefore authorizing submittal of the EWMP to Regional
Board is not a project for purposes of CEQA because it is not an approval of the plan. (14
Cal Code Regs. 15378(c).) Upon approval by the Regional Board, the City may undertake
implementing actions which will be reviewed pursuant to CEQA as appropriate.
FISCAL IMPACT
Aside from the project costs estimated in the tens of millions of dollars over the next
decades identified earlier in this report, Staff is still developing costs to implement the
GIMP and non-structural aspects of the EWMP on an annual basis. The GIMP is
expected to be approved by the Regional Board sometime this summer and monitoring
work will begin within 90 days of approval. The Draft FY2015-16 Budget has an allocation
of $190,000 for the GIMP program. The EWMP program is not expected to be approved
until early 2016 but the Draft FY2015-16 Budget allocates $100,000 to implement the
non-capital aspects of the program that will require immediate attention. These appear
to be sufficient for the coming year. Better estimates of annual costs will be known after
the EWMP has been approved and will be worked into future budgets.

Mr. John Dettle
Managing Engineer
CITY OF
City of Torrance, Public Works Department
20500 Madrona Avenue
Torrance, CA 90503
Dear Mr. Dettle:
RANCHO PALOS VERD ES
Thank you for including the City of Rancho Palos Verdes (RPV) in your stormwater best
management practice project to construct underground infiltration basins at the Torrance
Airport.
As a stakeholder in the Machado Lake watershed, the City of Rancho Palos Verdes is
pleased to be a partner with the City of Torrance in its request to the Proposition 1 Storm
Water Planning Grant Program. Funding for final design of underground infiltration
basins at Torrance Airport will help expedite project construction and provide coastal
cities with an excellent option for stormwater management. As currently envisioned, the
new basins will capture urban stormwater from RPV and other Peninsula communities
that otherwise flows into Machado Lake, an impaired water body, and it will also provide
for valuable groundwater recharge.
The City of Rancho Palos Verdes will commit to a pro -rated share of the matching funds
required for the Proposition 1 Storm Water Planning Grant Program and will enter into a
Memorandum of Understanding (MOU) with the City of Torrance that would outline the
specific roles and responsibilities as well as a proportional matching fund commitment
from each partner should the grant be awarded .
We hope to hear good news soon as it relates to the success of this application.
Sincerely,
Ken Dyda
