TITLE:
APPROVAL OF PROPOSITION 50 INTEGRATED REGIONAL WATER MANAGEMENT IMPLEMENTATION GRANT
APPLICATION FOR SAN DIEGO COUNTY LAGOON
POLLUTANT REDUCTION ASSESSMENT
CITY ATTY.
CITY MGR.
RECOMMENDED ACTION:
Adopt Resolution No. 2005-108 approving the City of Carlsbad’s application to the
Proposition 50 Integrated Regional Water Management (IRWM) Implementation Grant Program and
authorizing the Public Works Director or designee (Public Works Manager) as signature authority for
all related grant documents, i.e., correspondence and reports.
ITEM EXPLANATION:
The IRWM Grant Program is a joint program between the Department of Water Resources and the
State Water Resources Control Board which provides funding for projects to protect communities
from drought, protect and improve water quality, and reduce dependence on imported water.
A portion of these grants is available to local governments in the form of competitive grants for the
implementation of such projects. A 10% grant match from the grantee is required, which can be met
with in-kind services.
The City of Carlsbad has taken the lead on the grant application, however, the City will be sharing
the 10% grant match with the cities of Oceanside, Vista, San Marcos, Escondido, Solana Beach,
Encinitas, the County of San Diego, and the San Elijo Lagoon Conservancy. As partner agencies,
a project implementation proposal will be submitted as part of the grant process.
If awarded, the grant will fund the implementation of the San Diego County Lagoon Pollutant
Reduction Assessment Project, a project in partnership with all of the jurisdictions within the
watershed. This project addresses multiple high-priority pollutants in multiple watersheds throughout
the region. It will identify watershed and lagoon management options and estimation of
improvements to the lagoons to assist in development of watershed management plans and
effective Best Management Practices (BMPs). The project involves the design and implementation
of detailed monitoring and modeling studies of three coastal lagoons and their respective
watersheds. This will provide detailed information for use by the Regional Board, County of
San Diego, and various cities in the region to support regulatory and management decisions.
The Implementation Grant Step 1 application deadline is July 14, 2005. Approved projects are
expected to receive callbacks for Step 2 applications in November 2005.
ENVIRONMENTAL IMPACT
This project is categorically exempt from the environmental review process under Section 15306
Class 6 of the Public Resources Code (California, Environmental Quality Act).
FISCAL IMPACT:
The estimated award will be $1,536,737. In-kind services of Watershed Copermittees and water
quality and sediment monitoring from the Regional Copermittee Program with the Carlsbad
Watershed will cover the required 10% grant match ($1 53,700) and no excess funds are anticipated
to be spent towards this project.

H. LEGISLATIVE INFORMATION:
I 1 Requested Information
I. NEED FOR PROJECT:
The San Diego Region is home to over ten unique environmentally significant coastal
embayments; many of which are 303(d) listed as impaired for sediment, bacterial indicators and
nutrients (eutrophication). These coastal embayments represent a unique resource, distinctively
different than other coastal areas in the United States. This project focuses on three lagoons
(Buena Vista, Agua Hedionda and San Elijo Lagoons) that represent the three general lagoon
types in the region: tidally flushed sinuous embayment; tidally flushed open embayment, and
freshwater embayment. These three lagoons are all listed as impaired by sediment and bacteria
indicators and two (Buena Vista and San Elijo) are listed for nutrient (eutrophication) impairment,
which will all be the focus of this project. The watersheds of these lagoons are part of the unique
and fragile coastal sage and chaparral ecoregion, which is highly susceptible to damage caused
by anthropogenic activities such as urban expansion, agriculture, and livestock grazing.
Over 3 million people live among this fragile ecoregion of San Diego County. The many residents
and visitors of the area, while enjoying the environs, are also part of this system. As we consider
how to protect, preserve, and restore these systems, the physical, social and political features of
these watersheds must be incorporated into the decision process. When we discuss how to
analyze the system we first need to consider how the features of the watershed will define our
approach. A few selected features of the watershed are highlighted here. These features help to
illustrate why these coastal lagoons are different from other watersheds, yet can benefit from
studies in other lagoons. Some of the features that will shape the planning process include:
Large watershed areas relative to lagoon sizes and volumes
0 Multiple watershed inputs with limited monitoring to characterize the locations, timing, and
magnitude
0 Difficult to characterize sources of water and pollutants in dry-weather flows
0 Fine sediment and dissolved and particulate nutrients are key pollutants of concern
4
0 Variability of lagoon residence times could make changes difficult to perceive and pollutant
load reductions hard to evaluate
Unique hydraulic characteristics of each lagoon (e.g., flushing due to tidal variation, or
manmade berms that separate the lagoon from the ocean) can have significant impacts on
water quality and habitat
Preserving and/or restoring these watersheds and lagoons will require the formulation of a plan
that incorporates what is known about how watershed and riparian activities impact the lagoons
and how various management options affect conditions. Because these systems are unique to
southern California, there is a limited knowledge base from which to develop pertinent scientific
hypotheses as well as no known off-the-shelf models and tools to conduct integrated
assessments. To address both of these gaps, we are proposing a regionaVecoregional study that
will result in the collection of information needed to develop a conceptual model of these systems
and the design and development of a analytical toolbox that will be used to support planning
decisions that minimize anthropogenic impacts to San Diego’s unique coastal lagoons. Our
efforts will be focused on several pollutants and lagoons but the conceptual model, approach, and
tools will be transferable to other pollutants and southern California coastal watersheds.
Awareness of the environmental plight of the lagoons was heightened when the San Diego
Regional Water Quality Control Board (Regional Board) included the coastal lagoons on their list
of impaired waters and initiated the process of calculating Total Maximum Daily Loads (TMDLs)
for sediment, bacteria and nutrients. These TMDLs will provide a macro-scale assessment of the
pollutant loadings to the lagoons and will characterize the capacity of each lagoon to assimilate
these pollutant loads and still achieve established water quality objectives. In addition to the
TMDL calculations, the Regional Board will also develop quasi-generic plans with
recommendations and suggestions for achieving the load reductions. These implementation
plans will be based on available information and will not provide detailed guidance on the best
possible means of achieving the TMDLs. To ensure that these lagoons achieve all beneficial
uses, it will be important to develop a science-based implementation plan that considers source
loading associated with various flow conditions, source types and locations, and the cost and
effectiveness of various practices. The complexities associated with making these decisions will
require a regional approach that marries monitoring and modeling design considerations into a
single analytical framework.
TMDL’s are being developed, and will continue to be developed, that will require the region to
aggressively address pollutants into our coastal waters. Without good science in the form of
appropriate water quality data and accurate modeling of the systems to be improved, we risk
spending resources on solutions that do not address the correct issues. Local resources are
scarce and Best Management Practices (BMPs) must be applied with the utmost efficiency and
effectiveness. In short, decisions need to be based on good science and good science requires
that we have an understanding of our systems. This project will provide locally calibrated models
that can be applied regionwide. These models will improve our understanding of pollutant loading
and allow us to simulate implementation scenarios to determine cost effective BMP solutions to
achieve the goal of water quality improvement in the region.

Attachment 6. Description of Project
Begin Project Description Below this Line
This project addresses multiple high priority pollutants in multiple watersheds throughout the region. It will
produce a conceptual model, approach, and tools that will be transferable to other pollutants and southern
California coastal watersheds. It addresses sediment, bacteria and nutrients, which have been identified as high priority constituents of concern throughout the watersheds in the San Diego Region. The project
will identify watershed and lagoon management options and estimation of improvements to the lagoons to
assist in development of watershed management plans and effective Best Management Practices (BMPs).
As detailed below in the project description, this project supports three of the IRWM Plan Regional
Objectives:
It facilitates the integration of programs and strategies for enhancing the region’s water quality and
watersheds by integrating jurisdictional programs to assess water quality on a watershed basis,
supporting TMDL processes, and the goals of the California Nonpoint Source Program by
developing methods that can be used to attain water quality objectives;
It protects and enhances the health and viability of the region’s watersheds by providing a locally
calibrated computer model for pollutant reduction strategies; and
It supports regional efforts to attain or be consistent with statewide regulatory standards and
priorities including the TMDL program and Basin Plan.
This project includes a detailed plan for monitoring to provide essential information needed to develop
computer models of the lagoon systems. The monitoring program will be designed to support the
evaluation of conditions and the identification of sources. This information will be used with past and new
monitoring data to provide guidance and justification for the design and development of a modeling system
that can be used to guide future decisions and development of watershed protection plans. This approach
builds upon previous studies funded by the State Water Resources Control Board and the US.
Environmental Protection Agency (EPA) to support development of bacteria TMDLs (Total Maximum Daily
Loads) for the lagoons, and expands the monitoring and modeling efforts to address not only source
assessment, but also understanding of BMP strategies and benefits to the lagoons. In addition to the
direct benefits to the protection of the coastal lagoons, the evaluation of BMPs will provide valuable
information to support California’s Nonpoint Source Implementation Policy, including BMP evaluation and
tracking efforts such as the Nonpoint Source Encyclopedia
(httD://www.swrcb.ca.aov/nDs/encvcloDedia.html) and the Management Practice Miner
;). These tools have been developed to facilitate the
compilation and distribution of the limited information associated with BMP implementation and
effectiveness. It is expected that one of the outcomes of this study would be the availability of new
information on BMPs that will be provided to the County and Cities in the region for guidance in BMP
design, as well as the CA NPS program.
The proposed study involves the design and implementation of detailed monitoring and modeling studies of
three coastal lagoons and their respective watersheds. The three lagoons selected for this project are all
listed as impaired and they represent distinct categories specific to hydraulic and habitat characteristics in
the region. These include: lagoons that are generally open to the ocean and include a distinct tidal prism;
lagoons that are conditionally open to the ocean, depending on tidal elevation, and are therefore less
impacted by tides; and lagoons that are not normally open to the ocean, are not tidally influenced, and only
overflow to the ocean during storm events. The lagoons that are representative of these systems include
In addition to the requirements described here, the project description should be consistent with the work items shown in the
discussed in Attachment 7 (Cost Estimate) and Attachment 8 (Schedule) below.
9
San Elijo, Agua Hedionda, and Buena Vista, respectively. All three of these lagoons are impaired by
sedimentation and bacteria, and two are impaired by nutrients resulting in eutrophic conditions.
The resulting monitoring and modeling study provides detailed information for use by the Regional Board,
County of San Diego, and various Cities in the region to support regulatory and management decisions.
Results of this study will provide multiple benefits such as use in the development of TMDL implementation
plans, watershed management plans, and design of hydraulic controls for the lagoon. In addition, this study can provide guidance for management of similar lagoons and watersheds in San Diego County, and
will result in development of modeling tools that can be expanded for not only assessment of water quality
and sources of pollutants, but also detailed simulation of BMPs that can remedy impairments throughout
the region.
This project addresses multiple water management strategies, as follows:
Storm water capture and management, by collecting rare data to assess and evaluate BMP
effectiveness in reducing sediment and nutrient loads, and to model BMP design and placement for
future implementation;
0 Water quality protection and improvement by characterizing current water quality conditions and
assessment of trends in water quality and verifying sedimentation and eutrophication impairments.
NPS pollution control by calibrating an existing land-use-based model for pollutant reduction at a
watershed scale, and providing data on BMP effectiveness in support of the California Nonpoint
Source Implementation Plan.
Watershed planning by developing a conceptual model of watershed and lagoon systems and an
analytical toolbox that will be used to support planning decisions that minimize anthropogenic
impacts.

The Guiding Principles of the Regional Board's Watershed Management Initiative chapters are
implemented through this project as follows:
Geographic focus: The project is geographically focused on the watersheds within the Carlsbad
Hydrologic Unit and is applicable specifically to the southern California region.
Partnerships with Stakeholders: The project involves collaboration with the San Elijo Lagoon
Conservancy and will involve stakeholders within the study area, for example the Carlsbad
Watershed Copermittees, the Agua Hedionda Lagoon Foundation, the Buena Vista Lagoon
Foundation, the Carlsbad Watershed Network, Regional Board and other appropriate agencies
(private and public).
Coordinated Priority Setting: This project focuses resources on priority water quality issues as
identified in the Carlsbad Watershed Urban Runoff Management Plan, 2002. It also addresses the
Regional Board's 303(d) listed impairments for priority water segments.
Best Use of Resources: By developing load assessment tools, this project will prepare a
foundation for quantifying measurable water quality improvements. Also by using a combination of
existing models and water quality data, and targeted new data, this project cost effectively
leverages off of existing programs.
using a science-based approach.
Improved Decision Making: The purpose of this project is to improve decision-making capability
This project will result in the development of state-of-the-art planning tools to support watershed planning efforts, document improvements to water quality, and plan the design and siting of management practices
that will maximize environmental benefits in a cost-effective manner. This cost effectiveness is achieved
by using existing and targeted new monitoring data to expand and upgrade an existing model for lagoons.

The project proposes gathering data on multiple high priority watershed constituents of concern (sediment,
nutrients, bacteria) at one time in order to save money by not having to collect this information in separate
monitoring projects. Data management will be an important component of this work. This locally calibrated
computer model then allows the simulation of multiple BMP scenarios to determine the most effective
solutions for water quality improvement in a watershed (at this time, focusing on sediments). Because the
project involves modeling of three different types of coastal waterbodies, it allows for region-wide
applicability for other users.
PROGRAM COMPONENTS
TASK 1: Program Administration/Management
Project management and program administration will be performed by the Carlsbad Watershed
Copermittees. It will be accomplished by conducting regular stakeholder meetings and preparing or
directing the preparation of deliverables and required project reports. Initially, the need for a forma
agreement (MOU) will be determined. Project management will include coordinating the project
stakeholders, managing project budgets and timelines, and directing deliverables. On the average,
quarterly meetings of stakeholders will be held. These meetings will be attended by Carlsbad Watershed
Copermittees, the County, consultants, and other stakeholders as appropriate. Contract administration will
consist of contracting with the Regional Watershed Group, coordinating with the Regional Watershed
Group, developing appropriate reporting, and preparing invoices.
TASK 2: SAP and QAPP Development
The Sampling and Analysis Plan and the Quality Assurance Project Plan will be developed prior to the
collection of necessary water quality data.
TASK 3: Watershed monitoring
One of the main constraints that limits the effectiveness of models used for TMDL implementation is the
paucity of data available to validate the model. In this task, water quality data will be collected from the
major watersheds that drain into the three North County Lagoons: Buena Vista Lagoon, Agua Hedionda
Lagoon, and San Elijo Lagoon. Data will be collected during three periods: Winter Wet, Winter Dry, and
Summer Dry (Winter is from November 1 - March 31 and Summer is from April 1 - October 31). Where
necessary, Mass Loading Stations will be installed near the mouth of the major drainages, upstream of the
tidal prism for continual measurements of stream flow and velocity. Where appropriate, the San Elijo
Lagoon Conservancy network of rain gauges and continuous stream flow data will be used. Throughout
the dry periods (winter and summer), 24-hour composite samples will be collected and analyzed for grain
size, settleable solids concentration (SSC), and a variety of nutrients. Grab samples will also be collected
and analyzed for indicator bacteria. During the wet season, two storms will be monitored. Composite
samples will be collected and analyzed for the constituents discussed above. In addition, grab samples will be collected hourly at each site over the course of the storm to produce pollutographs for each of the
constituents. This combination of wet and dry weather sampling will allow for a very accurate assessment
of the total watershed loading of each of the constituents of concern.
Task 4: Lagoon Monitoring.
Although very little pollutant data is available for the watersheds that drain into the north county lagoons,
even less is available for the lagoons themselves. The models that drive the TMDLs are often based on
broad assumptions, with limited accuracy. The purpose of this Task is to provide accurate up to date
measures of loading and flux of the constituents of concern for each of the three lagoons. Flow meters will
be placed at the mouth of each lagoon to measure flux and produce rating curves. Rating curves will be established for both dry and wet weather periods. During dry weather, samples will be collected
throughout each of the lagoons during varying hydrodynamic periods and analyzed for parameters related
to sediment, nutrients, and indicator bacteria. Samples will also be collected at the mouth of each lagoon
during varying tidal stages to determine the flux of the nutrients of concern (except Buena Vista Lagoon,
which is closed to the ocean). During wet weather, the same parameters will be collected for each lagoon.
11
16
In addition, pollutographs for each of the constituents will also be produced during two storm events from
samples collected at the mouth of each lagoon. In addition, bathymetry surveys will be conducted for each
lagoon to facilitate model assumptions of pollutant transport. The combination of physical and chemical
data during both dry and wet weather periods will allow for a thorough understanding of the movement of
constituents through the lagoons, an estimate of pollutant loading to area beaches, and accurate model
predictions.
Task 5. Assess BMP Effectiveness.
One of the main focal points of this study is to assess the effectiveness of the existing BMPs in the three
watersheds focusing on sediment removal. There are numerous BMPs in place in the watershed designed
to limit or minimize pollutant loading to the receiving waters. For instance, within Carlsbad’s jurisdiction in
the Agua Hedionda Watershed, there are over 21 desilation basins. The effectiveness of specific BMPs
will be assessed by measuring pollutant reduction efficiency. This information can be used to calibrate the
model and allow for BMP simulations to be run as described later in this project description. Although the
exact procedure will depend on the function of the BMP, the assessment will likely include a survey of BMP
design characteristics (e.g., dimensions of detention pond, infiltration rate of bottom media, weir or pipe flow design for overtlow or draining, etc.), hourly loads entering and leaving the BMP, particle size
distribution of sediment, analyses of particulate nitrogen and phosphorus associated with sediment and
analyses of bacteria attached to sediment particles. In addition, an assessment of land use upstream of the
BMP will be incorporated into the analyses for future source tracking investigations.
A data management process will be developed that can be transferred throughout the region. The
Carlsbad Copermittees are currently working with the Regional Workbench Consortium, a UCSD
Supercomputer affiliate, to develop a web-based data and information management system that will be
expanded for this project.
Task 6. Modeling.
Model umrades for simulation of constituents of concern.
In the previous TMDL analyses, models were developed for the lagoons and their respective watersheds
for assessment of sources of bacteria and the assimilative capacity of the receiving waters. Watershed
models, which were based on EPAs Loading Simulation Program C++ (LSPC), provided dynamic
simulation of hydrology and bacteria build-up and wash-off processes resulting from various land use
activities in the watersheds. The LSPC models provide time-series estimates of watershed flows and
bacteria concentrations for input to separate receiving water models of the lagoons. Receiving water
models were based on the Environmental Fluid Dynamics Code (EFDC), and provide simulation of
hydrodynamics resulting from tides and storm flows, bacteria transport and die-off, and the resulting
assimilative capacities of the lagoons.
These models provide an excellent platform for upgrades that include simulation of sediment and nutrients.
In addition, additional bacteria data will be used to validate the model. The proposed study will provide
these upgrades and model calibration based on sediment, nutrient and bacteria data collected in the
watersheds and their respective lagoons. Model calibration will utilize existing and new data collected for
this project. Existing data will be collected from the Regional Monitoring Program, project partners and
stakeholders in the watershed, as practicable. The project will coordinate with the ongoing Carlsbad
Watershed Network State-funded Carlsbad Watershed Invasive Plant Removal Project that includes a
monitoring program. Of special interest to this project are the rain gauges and Hydrolab network data that
are currently, or planned to be, deployed in the watershed.
The models will facilitate analyses of sedimentation within the lagoon, as well as biological and chemical
processes that impact eutrophication. Based on these models, an assessment will be performed regarding
relative source contributions of various land use practices and impacts of watershed reductions on lagoon
water quality. Additionally, the EFDC model will facilitate analyses of impacts of alternative hydraulic
design strategies for lagoon outlets.
12
BMP Model development.
To support the placement and optimization of BMPs in the' watershed and riparian areas, additional
modeling tools will be developed and linked to the LSPC watershed model for dynamic simulation of the
control and removal of sediment. We are focusing the BMP modeling on sediment because a significant
portion of the nutrient load is associated with sediment, and therefore BMPs that reduce sediment will also
provide significant reductions to nutrients. The BMP modeling tool will utilize the output from the
watershed model and will provide hourly or daily simulation of volumetric or sediment transport processes
inherent in BMP designs, including such processes as detention and infiltration of water and associated
settling and filtration of sediment.
The monitoring phase of this study will provide essential information for configuration of the BMP model for
various BMPs currently used in the region for the control of sediment. As a pilot study, the BMP model will
be configured for site-specific BMPs monitored and calibrated based on flow and water quality data
collected. Once included in the modeling systems, the effectiveness of the BMPs can be assessed, as well
as ultimate benefits to improving conditions in the downstream lagoons. Alternative designs of these
BMPs will also be tested in the model to determine if improved results can be realized.
This regional calibration of the BMP model will provide a first phase for modeling of BMPs in the region. In
a second phase of study, the BMP model can be configured for the entire lagoon watersheds, facilitating
evaluation of alternative BMP designs at multiple sites and various designs. Multiple design strategies, or
model scenarios, can then be simulated and the resulting sediment load reductions and impacts to the
lagoons can be assessed. Because alternative design strategies have associated costs regarding BMP
size, construction, or maintenance, these relative costs can be included in evaluation through a cost- benefit analysis. Essentially, benefits associated with sediment reduction can be compared relative to
associated BMP costs, resulting in selection of the most cost effective BMP design for the watersheds.
Although this second phase is not included in the proposed study, completion of the first phase will provide
much information and progress toward the ultimate goal of developing regional tools for BMP selection
based on proven methods for evaluation of effectiveness and cost.
Task 7. Outreach.
Outreach efforts will be conducted through the Carlsbad Watershed Urban Runoff Management Program
(WURMP) and the Carlsbad Watershed Network (CWN). The CWN is a coalition of non-profit
organizations in the Carlsbad Watershed who are active in watershed protection. The outreach program
will consist of two main components: stakeholder involvement and public education. This task will be
performed through the existing, highly successful Carlsbad WURMP outreach group, the North County
Storm Water Programs, and the outreach workgroup of the CWN. Activities will be dove-tailed, as
appropriate, with the education activities of the ongoing, State-funded, Carlsbad Watershed lnvasives
Removal project. Information will be shared to stakeholders via the monthly CWN meetings. Special
stakeholder meetings may also be necessary to obtain input from lagoon stakeholders such as the Buena
Vista Lagoon Foundation, the Agua Hediona Lagoon Foundation, San Elijo Lagoon Conservancy,
Poseidon, Cabrillo Power Plant, Hubbs Seaworld Mussel Farm, Caltrans and the US Army Corp of Engineers.
The new CWN web site (www.carlsbadwatershednetwork.org) and the Project Clean Water website
(www.Drojectcleanwater.org) will be utilized as a public education platform. Educational materials will be
developed as appropriate to education the public about the importance of our lagoons and how to protect
them.
Task 8. Analysis and Report.
Following completion of the monitoring and modeling of the constituents assessed in this study, a
comprehensive report will be generated detailing the results. The report will provide a thorough analysis of
pollutant loading in the watersheds, their flux through the coastal lagoons, and eventual impact on area
beaches during both dry and wet weather conditions. The report will detail all monitoring events conducted throughout the study, provide thorough analysis of the results, as well as a comprehensive assessment of
