II. INTRODUCTION AND BACKGROUND
In March 2006, emergency channel dredging was conducted and completed in pot1ions of Agua
Hedionda and Calavera creek challllels to provide immediate flood protection for the residential
connnunity of Rancho Carlsbad. Emergency dredging was conducted in two phases. The first
phase involved removing vegetation and dredging within the charmel between the El Camino
Real and Catmon Road bridges. The second phase included dredging of the Agua Hedionda
creek channel from the El Camino Real Bridge, working eas tward (upstream) to the southem
bmmdary of Rancho Carlsbad Drive. To facilitate the work, the city issued an emergency
Coastal Development Pennit in Febnuuy 2006. Biological impacts associated with the
emergency wm:k are being mitigated.

The 2006 emergency dredge activities were required to address immediate flood control and
public safety needs of the Rancho Carlsbad community; however, long-term dredging,
improvements, and regular maintenance for the Agua Hedionda and Calavera creek channels
must be completed to restore and maintain the flood control capacity of the channels. In
response, a Coastal Development Permit (CDP), Special Use Permit-floodplain (SUP), and
Habitat Management Plan Permit (HMPP) were submitted.
On January 16, 2008 the Planning Commission approved a Coastal Development Permit (CDP
06-04), Special Use Permit-Floodplain (SUP 06-02), and a Habitat Management Plan Permit
(HMPP 06-03) for the Agua Hedionda and Calavera Creeks project for the dredging, improving,
and long-term maintenance of portions of Agua Hedionda and Calavera creek channels. In
addition, an Environmental Impact Report (EIR 04-02), Zone Code Amendment (ZCA 07-04)
and a Local Coastal Program Amendment (LCPA 07-06), were also approved for the City of
Carlsbad Drainage Master Plan Update. The two projects were approved together.
The CDP was appealed to the California Coastal Commission (CCC). Staff worked diligently
with the appellant, Preserve Calavera, and came to a compromise on several issues including the
location of the mitigation site within the Agua Hedionda watershed, which resulted in the
withdrawal of the appeal and the CDP to stand. The permits were due to expire on September
13, 2012; however, the city extended the permits for an additional two years (from September 13,
2012 to September 13, 2014) as the city pursues finalizing all required permits from the U.S.
Army Corps of Engineers (USACE), California Department of Fish and Wildlife (CDF&W)
and Regional Water Quality Control Board (RWQCB). The permits have not yet been obtained
so construction of the project has not begun.
The proposed project changes are a result of the city conducting additional engineering analysis
and the resource agencies requesting project changes. Staff evaluated whether project changes
would result in new or additional environmental impacts not adequately addressed in the certified
EIR. Furthermore, an amendment to the original CDP and SUP are also required since the
project changes are located within the floodplain and a portion of the amended project is within
the Coastal Zone.
The revised project continues to comply with the Drainage Master Plan, which incorporates this
project as basins “B” and “BN,” and the project EIR.
III. PROJECT DESCRIPTION
As stated previously, the proposed changes are the result of refined engineering analysis and the
changes requested by the resource agencies. Changes to the project include:
1. Installation of additional riprap along both banks of Agua Hedionda creek channel (rather
than a combination of riprap and bank stabilization with Vmax slope-treatment material);
2. Installation of riprap drop structures in place of gabion drop structures in Agua Hedionda
and Calavera creek channels;

3. Installation of a riprap structure in Agua Hedionda creek channel beneath the Cannon
Road bridge and in the Coastal Zone;
4. Installation of additional riprap along both banks of Agua Hedionda creek channel
between the Cannon Road and El Camino Real bridges and in the Coastal Zone; and
5. Removal of approximately 7,000 additional cubic yards of dredge material as earth in
the channel needs to be removed to accommodate the riprap.
The decision to install additional riprap along the banks of Agua Hedionda creek channel was the
result of refined engineering analysis that determined it was necessary to further protect the banks
from erosion. The change from gabion drop structures to riprap drop structures in both creek
channels was made at the request of the USACE, who expressed concerns related to the stability
of the previously proposed gabions. The inclusion of the riprap structure beneath the Cannon
Road bridge was made at the request of CDF&W, who expressed concerns with potential
sedimentation and/or erosion in the downstream habitat preserve.
The EIR (04-02) concluded that 278 of the 504 homes in this community were subject to 100-
year flood inundation. The proposed project is a part of a program of three flood control
projects. The city has already implemented two of the projects which included construction of
two major flood retention facilities: the repair and rehabilitation of the outlet works to Lake
Calavera Dam, and the construction of an 84” storm drain pipe paralleling Calavera Creek.
The dredging and improvement of the Agua Hedionda and Calavera Creeks is the third and final
project proposed for implementation. Currently, 168 homes remain in the flood inundation area.
With implementation of this amended flood control project, all but 22 homes would be removed
from the floodplain. The previous project would have removed all but 9 homes from the
floodplain; however, the change from a gabion drop structure to a riprap drop structure in Agua
Hedionda creek channel slightly reduced its capacity, as compared to the previously approved
project. Upon completion of channel dredging and improvements, a survey will be performed to
identify the exact number of homes that would remain within the floodplain.
As a result of the project changes, additional environmental impact analysis was performed by
AECOM to consider how these changes might affect the analysis and conclusions of project
impacts as they were presented in the certified EIR. Based on a preliminary review, AECOM
identified five environmental issues that needed to be addressed—Visual Resources (Section 4.3
of the 2007 EIR), Transportation/Circulation (Section 4.4), Air Quality (Section 4.5),
Hydrology/Water Quality (Section 4.9), and Greenhouse Gas Emissions (not included in the
2007 EIR). AECOM determined that the remaining sections of the 2007 EIR would not be
affected in any meaningful way by the changes in the project and do not warrant detailed
assessment. After further assessment, it was determined that the revised project is within the
scope of the certified EIR and an addendum to document the project changes is appropriate (see
Attachment 1).

IV. ANALYSIS
The project is subject to the following regulations and requirements:
A. General Plan;
B. Special Use Permit (Floodplain Management) Regulations (Chapter 21.110 of the
Carlsbad Municipal Code);
C. Coastal Development Regulations for the Mello II Segment of the Local Coastal Program
(CMC Chapter 21.201) and the Coastal Resource Protection Overlay Zone (CMC Chapter
21.203); and
D. Growth Management (CMC Chapter 21.90).
The recommendations for approval of this project were developed by analyzing the project’s
consistency with the applicable city regulations and policies. The project’s compliance with each
of the above regulations is discussed in detail in the sections below.
A. General Plan
TABLE 1 - GENERAL PLAN COMPLIANCE
ELEMENT GOAL, OBJECTIVE,
POLICY OR PROGRAM
PROJECT CONSISTENCY
Public Safety A City which minimizes
injury, loss of life, and
damage to property resulting
from the occurrence of floods
(Flood Hazards – Goal A).
The dredging of Agua Hedionda and Calavera
creek channels in particular would protect
approximately 146 homes in Rancho Carlsbad
against the threat of flooding.
Open Space
&
Conservation
To control storm water
pollutants (Water Quality
Protection – Objective B.1).
Construction of drainage improvements and
facilities would be subject to compliance with
all regulations imposed by the city and other
agencies to ensure storm water quality.
Open Space
&
Conservation
To design storm water
conveyance systems that do
not adversely impact
sensitive environmental
resources (Water Quality
Protection – Objective B.2).
The inclusion of the riprap structure beneath the
Cannon Road bridge, which was made at the
request of the CDF&W, will reduce
sedimentation and/or erosion in the downstream
habitat preserve, including Agua Hedionda
Lagoon.
B. Special Use Permit (Floodplain Management) Regulations (Chapter 21.110 of the
Carlsbad Municipal Code)
The additional project components within the Agua Hedionda and Calavera creek channels
require an amendment to SUP 06-02x1 per Zoning Ordinance Chapter 21.110. The amended
EIR 04-02(A)/CDP 06-04x1(A)/SUP 06-02x1(A) – AGUA HEDIONDA & CALAVERA
CREEKS

project complies with the requirements of this Chapter, including its statement of purpose, in that
the proposed changes with the dredging and improvements would continue to benefit the Rancho
Carlsbad residential community by protecting human life and health, minimizing the need for
rescue and relief efforts associated with flooding, and minimizing damage to utilities.
As mentioned above, the amended project would protect nearly 146 of the 168 dwelling units
currently located within the FEMA flood hazard zone. Upon completion of channel dredging
and improvements, a survey will be performed to identify the exact number of homes that would
remain within the floodplain.
The project also includes a maintenance plan to ensure periodic dredging and maintenance
continues so that residences remain protected. The amended project also proposes no buildings,
structures or habitable components that would potentially expose people or property to flooding
hazards.
Furthermore, the amended project would not create any additional hazard or cause adverse
impacts to downstream properties or structures, or reduce the ability of the site to pass or handle
a base flood of 100-year frequency, in that immediately below the project Agua Hedionda creek
channel opens to a wide undeveloped floodplain that extends to the Agua Hedionda Lagoon,
which would allow Agua Hedionda and Calavera creek channels to pass floodwaters of such
frequency.
C. Coastal Development Regulations for the Mello II Segment of the Local Coastal
Program (CMC Chapter 21.201) and the Coastal Resource Protection Overlay Zone (CMC Chapter 21.203)
The proposed project amendments are in conformity with the public access and recreation
policies of Chapter 3 of the Coastal Act in that the project involves dredging of existing creek
channels that are not navigable, used for recreation, or bordered by public trails or recreation
areas. Further, the project is consistent with the provisions of the Coastal Resource Protection
Overlay Zone (Chapter 21.203 of the Zoning Ordinance) in that the project will adhere to the
city's Master Drainage Plan (as well as the proposed Drainage Master Plan Update), Grading
Ordinance, Storm Water Ordinance, Standard Urban Storm Water Mitigation Plan (SUSMP),
and Jurisdictional Urban Runoff Management Program (JURMP) to avoid increased urban
runoff, pollutants, and soil erosion.
No steep slopes are located on the subject property and the site is not located in an area prone to
landslides. The existing Local Coastal Program (LCP) requires storm drainage facilities in
developed areas to be improved and enlarged according to the City’s existing Master Drainage
Plan and thus it is the intent of the LCP, as noted above, to allow implementation of drainage
projects that are part of the city’s drainage master planning program.
Furthermore, LCP Policy 4-3(b)(3)(a), requires all development to include measures to reduce
flow rates, velocities, erosion, and sedimentation for drainage and erosion control. The
additional riprap between the El Camino Real and Cannon Road bridges (the portion of the
EIR 04-02(A)/CDP 06-04x1(A)/SUP 06-02x1(A) – AGUA HEDIONDA & CALAVERA
CREEKS

project within the Coastal Zone) is necessary to further protect the banks from erosion and reduce
the amount of potential sedimentation and/or erosion in the downstream habitat preserve.
D. Growth Management (CMC Chapter 21.90)
The Agua Hedionda and Calavera Creeks project is in four Local Facility Management Zones (8,
14, 15, and 24) since these zones all converge at the intersection of El Camino Real and Cannon
Road. Because the dredging and improvements proposed involve no construction or
development of habitable structures or uses, they would also not impact the city’s ability to plan
or provide public services. By enhancing flood protection for Rancho Carlsbad, the proposal
complies with the Growth Management Ordinance requirement of adequate drainage.
V. ENVIRONMENTAL REVIEW
To provide environmental review consistent with the California Environmental Quality Act
(CEQA), the city consulted with environmental firm AECOM to determine if the revisions to the
amended project would trigger a supplemental or subsequent EIR, or if a simpler document, an
addendum, could be prepared. AECOM prepared the project’s EIR that the city certified in 2008.
Supplemental and subsequent EIRs require public noticing and review periods similar to that
required for Draft EIRs. Unlike addendums, they are necessary to use when a previously
certified EIR is no longer adequate to cover the impacts of the changed project.
As explained below, staff has reviewed the project changes and found that none of the
requirements in CEQA Guidelines sections 15162 or 15163 for supplemental or subsequent EIRs
have been triggered. Therefore, the revised project is within the scope of the certified EIR and
use of an addendum to document the project changes is appropriate.
CEQA Guideline Section 15162 requires a subsequent EIR if:
1. Substantial changes are proposed in the Project which will require major revisions to the
previous EIR due to the involvement of new significant environmental effects or a
substantial increase in the severity of previously identified significant effects;
2. Substantial changes occur with respect to the circumstances under which the project is
undertaken which will require major revisions to the previous EIR; or
3. New information of substantial importance, which was not known and could not have
been known with the exercise of reasonable diligence at the time the previous EIR was
certified.
CEQA Guideline Section 15163 requires a supplemental EIR if:
1. Any of the conditions described in Section 15162 would require the preparation of a
subsequent EIR; and

2. Only minor additions or changes would be necessary to make the previous EIR
adequately apply to the project in the changed situation.
In preparing the recommended Addendum, staff determined none of the conditions warranting a
subsequent or supplemental EIR were met as the following findings show:
1. There are no significant new environmental effects and no substantial increase in the
severity of a previously identified significant effect. The analysis and mitigation
contained in EIR 04-02 remain adequate to address all modifications proposed.
2. There has been no substantial change with respect to the circumstances under which the
Project is being undertaken which would require major revisions to EIR 04-02.
3. There is no new information of substantial importance that was not known and could not
have been known with the exercise of reasonable diligence at the time EIR 04-02 was
certified.
4. The Project will not have any significant effects not discussed in EIR 04-02.
5. There are no new or additional mitigation measures that need to be added and there are no
mitigation measures previously found not to be feasible that are now found to be feasible
that would substantially reduce one or more significant effects of the Project.
The recommended Addendum to the previously certified EIR documents the changes included in
the permit amendments and is included as an attachment to Resolution No. 6950.

PLANNING COMMISSION RESOLUTION NO. 6376
A RESOLUTION OF THE PLANNING COMMISSION OF THE
CITY OF CARLSBAD, CALIFORNIA, RECOMMENDING
CERTIFICATON OF AN ENVIRONMENTAL IMPACT
REPORT AND ADOPTION OF CANDIDATE FINDINGS OF
FACT AND A MITIGATION MONITORING AND
REPORTING PROGRAM FOR THE DRAINAGE MASTER
PLAN UPDATE.
CASE NAME: CITY OF CARLSBAD DRAINAGE MASTER
PLAN UPDATE/AGUA HEDIONDA AND
CALA VERA CREEKS
CASE NO: EIR 04-02
WHEREAS, the City of Carlsbad, "Applicant," has filed a verified application
with the City of Carlsbad to adopt a city-wide Drainage Master Plan, an update to the current
Master Drainage Plan previously adopted in 1994 and amended in 1996; and
WHEREAS, an Environmental Impact Report -EIR 04-02 was prepared in
conjunction with the City of Carlsbad Drainage Master Plan Update ("Project") in compliance
with the California Environmental Quality Act (CEQA); and
WHEREAS components of both the existing Master Drainage Plan and l?roject
include the dredging of portions of Calavera and Agua Hedionda creeks for enhanced flood
control; and
WHEREAS, following public circulation and notice of the Final
Environmental Impact Report (Final EIR), staff determined necessary additional minor
text changes to the Final EIR as shown in attached exhibit "EIR-C." These changes clarify
that the number of lots in the Rancho Carlsbad community that would remain subject to at
least partial inundation during a 100-year storm event, is an approximate, rather than a
specific or maximum number; and
WHER~AS, the minor text changes merely clarify discussion already
contained in the Final EIR. As such, recirculation of the Final EIR is not required because

the new information added to the EIR makes insignificant modifications to an adequate
EIR (CEQA Guideline, 15088.5(b)); and
WHEREAS, the Planning Commission did on January 16, 2008 hold a duly
noticed public hearing as prescribed by law to consider said request; and

For the
FINAL ENVIRONMENTAL IMPACT REPORT (EIR 04-02)
For the
CITY OF CARLSBAD DRAINAGE MASTER PLAN UPDATE
(SCH No. 2006041 066)
Findings of Fact
1.1 INTRODUCTION
A Final Environmental Impact Report (Final EIR) has been prepared pursuant to the California
Environmental Quality Act (CEQA), the CEQA Guidelines, and Chapter 19.04 (Environmental
Protection Procedures) of the Carlsbad Municipal Code to address the potential environmental
effects of the City of Carlsbad (City) Drainage Master Plan Update (DMP Update; the Project)
and considered by City Council in connection with its public consideration of requested
approvals for the Project. The full scope of the Project and associated approvals are described in
more detail in Section 1.2 below.
The Project consists of an update to the City's existing Master Drainage and Storm Water
Quality Management Plan. The DMP Update is a comprehensive planning document that serves
to assess existing storm drain infrastructure and drainage areas; identify anticipated improvements
and additional infrastructure required to prevent flooding and accommodate storm flows resulting
from future development within the city; and provide guidance on developing a Planned Local
Drainage Area (PLDA) fee program to facilitate construction of specific drainage facilities
required for new development. A program level environmental analysis has been prepared for
most of the project components proposed in the DMP Update, as well as for proposed operation
and maintenance activities.
In addition to the program level analysis, two project components identified with the DMP
Update are at a point in the design process that enables a project level analysis. Specifically, the
City has initiated design of the Agua Hedionda and Calavera Creeks Dredging and
Improvements Project (identified in the DMP Update as project components B and BN and
identified by the city-issued permits for the dredging project as "Agua Hedionda and Calavera
Creeks"). Project components B and BN involve drainage infrastructure modifications and
improvements along Agua Hedionda and Calavera creeks to provide flood protection for Rancho
Carlsbad, an existing residential community. Because project components B and BN are in the
design phase, they are evaluated at a project level in the Final EIR and are part of the Project as
defined herein). The Final EIR and its separately bound technical appendices are incorporated
herein by reference as though fully set forth.
The following statement of facts and findings ("Findings") has been prepared in accordance with
CEQA, for use by the City in connection with its actions as Lead Agency for the Project.

Carlsbad. The City Council received, reviewed, and considered all of the information and
documents in the record.
1.1.3 Overview of Project Impacts and CEQA Findings
The Final EIR assesses the potentially significant impacts of the DMP Update and identifies the
following categories of impacts:
(1) Potential impacts that would be "less than significant"; and
(2) Potential impacts that would be mitigated to a level that is "less than significant
with the implementation of mitigation measures identified in the Final EIR."
(3) Potential impacts that would be "significant and unrnitigable" because they could
not be reduced to a less than significant level with the implementation of
mitigation measures.
The DMP Update would not result in impacts that would be "significant and unmitigable."
CEQA Findings of Fact 4 January 16, 2008
EIR 04-02 Carlsbad Drainage Master Plan Update
Findings of Fact
The City is acting as the Lead Agency for the Project under CEQA. As the Lead Agency, the
City is responsible for making certain written .Findings related to the Project prior to approval of
the DMP Update.
Pursuant to CEQA Sections 21081 and 21081.5 and CEQA Guidelines Sections 15091 and
15096(h), for each significant Project impact identified in the Final EIR [i.e., categories (2) and
(3) above], the City must make one or more of the following Findings:
(1) Changes or alterations have been required in, or incorporated into, the Project that
avoid or substantially lessen the significant environmental effect.
(2) Such changes or alterations are within the responsibility and jurisdiction of
another public agency (other than the City), and such changes have been, or can
and should be, adopted by such other agency.
(3) Specific economic, legal, social, technological, or other considerations make
infeasible the mitigation measures or project alternatives identified in the Final
EIR.
CEQA defines "feasible" to mean "capable of being accomplished in a successful manner within
a reasonable period of time, taking into account economic, environmental, social and
technological factors" [CEQA § 21061.1]. The CEQA Guidelines add "legal" considerations as
an additional factor in determining feasibility [CEQA Guidelines § 15364]. In addition, if the
Finding in (3) above is made with respect to any significant Project impact, the City must make a
Finding, based upon substantial evidence in the record, that specific overriding economic, legal,
social, technological, or other benefits of the Project outweigh the significant effects on the
environment [CEQA §§ 21081(b), 20181.5; CEQA Guidelines§ 15093].
The Findings set forth in this document have been prepared pursuant to CEQA Sections 21081
and 21081.5 and CEQA Guidelines Sections 15091, 15092, 15093, and 15097 to address the
environmental effects of the Project set forth in the Final EIR as modified.
1.1.4 Mitigation Monitoring Reporting Program
A Mitigation Monitoring Reporting Program (MMRP) has been prepared and will be adopted as
part of the conditions of approval of the DMP Update, pursuant to CEQA Section 21 081.6 and
CEQA Guidelines Section 15097. A copy of the MMRP is included as Exhibit B to this
Resolution and incorporated herein by this reference.
1.2 PROJECT DESCRIPTION
1.2.1 Project Location
Program Level
The DMP Update proposes project components located within Carlsbad, in the northern part of
San Diego County. The City encompasses approximately 42 square miles and is divided into
CEQA Findings of Fact 5 January 16, 2008
EIR 04-02 Carlsbad Drainage Master Plan Update
Findings of Fact
four major drainage basins, which all ultimately drain to the Pacific Ocean. These four basins
(Basins A, B, C, and D) roughly correspond to the four local watersheds (Buena Vista Creek,
Agua Hedionda Creek, Encinas Creek, and Batiquitos Lagoon). Basins A, B, and D extend
outside of city limits, while Basin C is included entirely with the jurisdictional boundaries of the
City. All project components would be located within the City's jurisdictional borders.
Basin A (Final EIR, Figure 3-1) is located in the northern portion of Carlsbad. It is bordered by
State Route 78 and Oceanside to the north, the Pacific Ocean to the west, generally Carlsbad
Village Drive to the south, and College Boulevard to the east. Basin A is the smallest basin
within the Carlsbad drainage area, occupying approximately 2,270 acres within the Buena Vista
Creek Watershed.
Basin B (Final EIR, Figure 3-2) is located directly south of Basin A. The northern basin
boundary roughly follows Carlsbad Village Drive. The southern boundary incorporates Palomar
Airport Road, Cannon Road, and College Boulevard. The basin extends east from the coast to
the city boundary, occupying approximately 9,340 acres within the Agua Hedionda Creek
Watershed.
Basin C (Final EIR, Figure 3-3) is located in the center of the city and encompasses
approximately 2,580 acres within the Encinas Creek Watershed. The northern boundary includes
a portion of Palomar Airport Road, Cannon Road, and College Boulevard. The western
boundary is the Pacific Ocean, while the southern boundary follows Poinsettia Lane and
El Camino Real. The eastern boundary of the basin follows El Camino Real, with a small
extension out along Palomar Airport Road east of El Camino Real. A large segment of
McClellan-Palomar Airport Road runs through the center of this basin.
Basin D (Final EIR, Figure 3-4) is located in the southern portion of the city. The southern
boundary is. the same as Carlsbad's boundary with Encinitas. The western boundary is the
Pacific Ocean. The northern boundary includes Poinsettia Lane and El Camino Real. The
eastern boundary follows Rancho Santa Fe Road and the city's border with Encinitas and
San Diego County. Basin D is the largest basin, encompassing approximately 10,907 acres
within the Batiquitos Lagoon Watershed (City of Carlsbad 2006a).
Project Level
Project components B and BN are located within the Aqua Hedionda Creek Watershed. These
DMP Update project components, described in more detail below, would provide flood
protection for Rancho Carlsbad. Agua Hedionda and Calavera creeks flow within constructed
earthen channels through Rancho Carlsbad, except under bridges where riprap sides exist. Agua
Hedionda Creek (Project component B) flows west through the southwestern portion of Rancho
Carlsbad, bends southwest at the confluence with Calavera Creek, and exits the Rancho Carlsbad
community under El Camino Real. West ofEl Camino Real, Agua Hedionda Creek bends west,
where it passes beneath Cannon Road and flows into a natural stream channel that drains into
Agua Hedionda Lagoon. Two road crossings, Cannon Road Bridge and El Camino Real Bridge,
are located within the downstream portion of the proposed work area. The length of work in
Agua Hedionda Creek within the project boundary is approximately 3,000 linear feet (LF),
CEQA Findings of Fact 6 January 16, 2008
EIR 04-02 Carlsbad Drainage Master Plan Update
Findings of Fact
extending from approximately 100 feet below the downstream edge of Rancho Carlsbad Drive
Bridge to the downstream edge of Cannon Road Bridge.
Calavera Creek (Project component BN) originates from Lake Calavera and meanders in a
southerly direction through open space, then flows south through an 11-foot by 7-foot reinforced
concrete box culvert under the intersection of College Boulevard and Cannon Road, and enters
the Rancho Carlsbad community at the point of confluence with a tributary known as Little
Encina Creek. Calavera Creek then flows southwest, along the northwest boundary of the
Rancho Carlsbad community, to a point of confluence with Agua Hedionda Creek, located
approximately 300 feet east of El Camino Real. The approximate length of Calavera Creek
within the project boundary is 3,400 LF, extending from the box culvert at the intersection of
Cannon Road and College Boulevard to the confluence with Agua Hedionda Creek.
1.2.2 Project Description
Program Level
As a comprehensive planning document, the DMP Update is comprised of PLDA projects
(subject to the PLDA fee program), operation and maintenance activities, and non-PLDA
projects. Under the PLDA fee program, fees paid by developers are used by the City to construct
and maintain storm water infi-astructure required for accommodating the increased storm water
flows resulting from new development. Non-PLDA projects involve improvements to drainage
facilities that are public facilities but are not required to accommodate additional storm flows
generated from new development. Because non-PLDA projects do not address impacts of new
development, they are not funded by the PLDA fee. In addition, the DMP Update identifies
Capital Improvement Projects (CIPs), which involve improvements to existing drainage facilities
and are considered non-PLDA projects in the DMP Update. Operation and maintenance-related
activities for both PLDA and non-PLDA project components are also included in the DMP
Update but would not be funded through the PLDA fee program.
PLDA projects included in the DMP Update would involve drainage infrastructure components
and activities, including (but not limited to) reinforced concrete pipe, concrete trapezoidal
channels, soft bottom trapezoidal channels, drainage inlets, manhole cleanouts, junction
structures, perforated subdrains, gabion structures, sediment basins, water quality basins, erosion
and scour protection, slope stabilization, installation ofVmax, and bridge construction.
Non-PLDA projects, including CIP projects, encompass both proposed facilities and existing
facilities that are now considered for rehabilitation but would not be funded by the City's PLDA
program because they are not intended to accommodate additional storm flows generated from
proposed new development. Proposed non-PLDA projects included in the DMP Update would
involve drainage infrastructure components and activities, including (but not limited to) those
described above for PLDA projects. Details of these general activities proposed as part of the
DMP Update are found in Sections 3.3.5 and 3.3.6 of the Final EIR.
Tables 3-1 and 3-2 of the Final EIR list the proposed PLDA and non-PLDA projects identified
by the DMP Update.
CEQA Findings of Fact 7 January I 6, 2008
EJR 04-02 Carlsbad Drainage Master Plan Update
Findings of Fact
Operation and maintenance of existing and proposed drainage facilities are an essential
component for the proper and efficient function of city infrastructure. While operation
and maintenance activities are anticipated for all city drainage facilities, including both
PLDA and non-PLDA DMP Update components, these proposed activities are long-term
commitments that would not be paid for by private developers and would therefore not
receive funding from the PLDA fee program.
Proposed operation and maintenance activities have been grouped into a number of
categories, including (but not limited to) Inlet/Outlet and Channel Maintenance, Existing
Facilities Repair, Facility Rehabilitation/Upgrades (Non-capacity Related), Culvert
Replacement and Roadway Rehabilitation, Bridge Rehabilitation/Replacement, Storm
Drain Infrastructure Repair, Sedimentation/Retention/Water Quality Basin Maintenance
and Repair, and Jurisdictional Dam operation and maintenance. Each of these categories
is discussed in greater detail in Section 3.3.6 of the Final EIR.
Project Level
Project components B and BN are proposed to provide flood protection for the Rancho
Carlsbad residential community by improving the capacity of Aqua Hedionda and
Calavera creeks (within Rancho Carlsbad) to contain a 100-year flood event, to the extent
feasible. Both project components contain both PLDA and non-PLDA elements.
Proposed PLDA project component B involves channel improvements along
approximately 3,000 LF of an existing tributary that conveys runoff from Agua Hedionda
Creek and adjacent open areas. PLDA project component B would involve dredging
portions of Agua Hedionda Creek to widen the creek at its confluence with Calavera
Creek, improving conveyance capacity of the channel for containment of a 1 00-year
flood event, collecting on-site and off-site storm water runoff, and minimizing flooding
of segments of Agua Hedionda Creek adjacent to the Rancho Carlsbad residential
community. Proposed improvements would entail dredging, dewatering, possible beach
disposal of sand and sediment from within the channel banks, possible bridge
stabilization, and on-site restoration where appropriate.
PLDA project component BN would involve excavation and enhancement of Calavera
Creek. Modifications include installation of gabion structures, removal of miscellaneous
concrete, and bank stabilization.
Upon completion of channel dredging improvements, long-term maintenance of both
Agua Hedionda and Calavera creeks would be required to maintain flood control capacity
(i.e., contain 100-year flood events). Project components B and BN both propose non-
PLDA components, including long-term channel maintenance in the form of periodic
inspections; sediment, debris, and, vegetation removal; and repair of eroded surfaces
associated with drainage and bridge appurtenances. ·
With implementation ofPLDA project components Band BN, all but approximately nine·
of the lots in Rancho Carlsbad would receive protection from a 100-year flood event.
CEQA Findings of Fact 8 January 16, 2008
EIR 04-02 Carlsbad Drainage Master Plan Update
Findings of Fact
1.2.3 Project Objectives
Implementation of the proposed DMP Update (including proposed PLDA, non-PLDA, and
operation and maintenance activities) would accomplish the following objectives:
• address existing and anticipated future drainage infrastructure deficiencies within the city
at a basinwide level;
• provide facilities to accommodate storm flows from future development contemplated by
the City's General Plan;
• provide facilities to accommodate anticipated drainage infrastructure needs in the city,
either through rehabilitation and replacement of aging infrastructure or implementation of
new facilities necessary to accommodate generalized future development; and
• provide for necessary long-term infrastructure operation and maintenance activities to
ensure public safety, reduction of flood hazards, and storm water quality control.
The DMP Update does not directly address storm water quality because the City now has
separate planning documents for storm' water quality control. However, a benefit of the DMP
Update is that it would indirectly protect and improve water quality by improving storm water
conveyance, reducing erosion, and removing sediments and/or contaminants.

1.3 FINDINGS REGARDING THE ENVIRONMENTAL REVIEW PROCESS
The City, acting as Lead Agency for the environmental review of the DMP Update under CEQA,
makes the following Findings with regard to the environmental review process undertaken to
analyze potential environmental impacts of the DMP Update.
(1) In accordance with CEQA Guidelines Section 15060(d), the City determined the
Project would clearly require an EIR and therefore did not prepare an Initial
Study.
(2) The City issued its Notice of Preparation (NOP) on March 29, 2006. The NOP
was distributed to all responsible and trustee agencies, as well as other agencies
and members of the public (Appendix A of the Final EIR), and was published in a
local newspaper. A number of written responses were received.
(3) The City held a public scoping meeting on April 12, 2006, at the City's Faraday
Center. Advance notice of the meetings was given in the NOP. At the scoping
meeting, the public was invited to comment on the scope and content of the EIR.
Oral and written comments were received. A copy of the NOP and the written
comments received in response to the NOP and public scoping process are
included in Appendix A of the Final EIR.
(4) The following substantive potential impact areas were identified for the
environmental impact analysis:
• Land Use • Transportation/Circulation
• Agricultural Resources • Noise
• Visual Resources • Air Quality
• Recreation • Biological Resources
• Geology/Soils • Cultural Resources
• Hydrology/Water Quality • Paleontological Resources
Additionally, the Final EIR includes other substantive sections required by
CEQA, such as executive summary, project description, cumulative effects,
effects found not to be significant, and growth inducing effects and alternatives.
CEQA Findings of Fact 10 January 16, 2008
EIR 04-02 Carlsbad Drainage Master Plan Update
Findings of Fact
(5) The Draft EIR for the DMP Update was circulated for public review for a period
of 45 days, which started on July 16, 2007, and ended on August 31, 2007. A 15-
day extension of the public review period was granted, enabling additional
comments to be received through September 14, 2007. The Draft EIR was
distributed to a variety of public agencies and individuals. A Notice of
Completion (NOC) of the Draft EIR was published in a local newspaper. The
NOC included information on locations, including the City's website, where the
EIR as well as the proposed Drainage Master Plan Update document would be
available to the public.
( 6) The City has considered, and responded to, public comments on the Draft EIR.
The City determined that recirculation of the Draft EIR was not required.
Responses to comments received on the Draft EIR are included in Appendix F of
the Final EIR.
(7) The City released the Final EIR for public review in December 2007. The Final
EIR was distributed to all responsible and trustee agencies as well as all agencies
and members of the public that submitted written comments on the Draft EIR.
The City made public the release of the EIR through an announcement on its
website where the Final EIR would be available to the public.
(8) Prior to certification of the Final EIR, the City Council has not made any
decisions that constitute an irretrievable commitment of resources or a
commitment to a definitive course of action with respect to the DMP Update.
2.0 FINDINGS REGARDING POTENTIAL ENVIRONMENTAL IMPACTS
DETERMINED TO HAVE NO IMPACT OR TO BE LESS THAN SIGNIFICANT
The City hereby finds that the following potential environmental impacts of the DMP Update are
less than significant and therefore do not require mitigation measures.
2.1 LAND USE
2.1.1 Program Level
Finding: Implementation of the DMP Update would not result in program level land use impacts
associated with the Significance Criteria discussed in Section 4.1.2 of the Final EIR.
Specifically, the DMP Update components would not:
• result in the physical division of the communities within the city,
• conflict with any applicable land use plan, policy, or regulation, or
• conflict with the City's Habitat Management Plan (HMP).
Facts in Support: Proposed DMP Update components would not physically divide the
communities within the city because construction and operation of the proposed DMP Update
CEQA Findings of Fact 11 January 16, 2008
EIR 04-02 Carlsbad Drainage Master Plan Update
Findings of Fact
components would primarily occur in existing drainages or rights-of-way within developed
areas, or natural drainages within open space areas. Therefore, program level impacts would be
less than significant.
The proposed DMP Update would not conflict with existing land uses and designations because
the components would be consistent with City land use plans and policies, including the
Carlsbad General Plan, Zoning Ordinance, Floodplain Management Regulations, Growth
Management Program, Local Facilities Management Plans, Land Use Compatibility Plan
(LUCP) for McClellan-Palomar Airport, Open Space and Conservation Management Plan, and
Local Coastal Program. Therefore, program level impacts resulting from conflicts with land use
plans, policies, and regulations would be less than significant. The DMP Update's consistency
with each of the aforementioned land use plans arid policies is detailed in Section 4.1.3.1 of the
Final EIR.
The proposed DMP Update would not result in any land use conflict with the City's HMP
because design features/methods and construction measures have been incorporated into the
project design that result in the avoidance of potential conflicts with the City's HMP. These
measures include installation of temporary fencing along Coastal Zone/HMP boundaries adjacent
to constructing/staging areas; limitations and regulation of vehicle access to construction sites;
identification of designated staging areas for storage of construction equipment/materials,
parking, or other construction-related activities; and designation of staging areas for
equipment/vehicle fueling at a minimum distance of 50 feet away from HMP boundaries.
Additionally, appropriate catchment basins/devices shall be used to prevent the flow of fuel, and
construction equipment shall be checked for leaks prior to operation and repaired as necessary.
The City would verify that these measures occurred prior to the first preconstruction meeting for
each component. Therefore, the DMP Update would not conflict with the requirements of the
HMP. These measures are further detailed in Table 3-6 of the Final EIR.
2.1.2 Operation and Maintenance
Finding: Implementation of proposed operation and maintenance activities would not result in
land use impacts associated with the Significance Criteria discussed in Section 4.1.2 of the Final
EIR and restated above in Section 2.1.1.
Facts in Support: Proposed operation and maintenance activities would not physically divide a
community within the City because proposed activities would occur within existing or proposed
drainage facilities. Therefore, impacts associated with operation and maintenance activities
would be less than significant.
Proposed operation and maintenance activities would not conflict with any existing land uses and
designations because the component parts would be consistent with City land use plans and
policies, including the Carlsbad General Plan, Zoning Ordinance, Floodplain Management
Regulations, Growth Management Program/ Local Facilities Management Plans, LUCP for
McClellan-Palomar Airport, Open Space and Conservation Management Plan, and Local Coastal
Program. Therefore, impacts resulting from conflicts with land use plans, policies, and
CEQA Findings of Fact 12 January 16, 2008
EIR 04-02 Carlsbad Drainage Master Plan Update
Findings of Fact
regulations would be less than significant. The DMP Update's consistency with each of the
aforementioned land use plans and policies is detailed in Section 4.1.3.1 of the Final EIR.
Proposed operation and maintenance activities associated with the DMP Update would not result
in any land use conflict with the City's HMP because design features/methods and construction
measures have been incorporated into the project design that result in the avoidance of potential
conflicts with the City's HMP. These measures, discussed in Section 2.1.1 above and detailed in
Table 3-6 of the Final EIR, will be verified by the City prior to the first preconstruction meeting
for each component of the DMP Update. Therefore, operation and maintenance activities would
result in less than significant land use conflicts with the City's HMP.
2.1.3 Project Level
Finding: Implementation of the proposed Agua Hedionda and Calavera Creeks Dredging and
Improvements (DMP Update project components B and BN) would not result in land use
impacts associated with the Significance Criteria discussed in Section 4.1.2 of the Final EIR and
restated above in Section 2.1.1.
Facts in Support: Proposed project components B and BN would not physically divide a
community within the city because the proposed dredging and improvements in Aqua Hedionda
and Calavera creeks would occur within the existing drainage facilities and do not involve the
construction of any new structures. Therefore, project level impacts associated with components
B and BN would be less than significant.
Proposed project components B and BN would not conflict with existing land uses and
designations because proposed improvements do not involve change in existing land use or
zoning designations. Additionally, proposed project components B and BN are not located
within the McClellan-Palomar Airport LUCP. There are no conflicts with land use plans,
policies, and regulations; therefore, project level impacts associated with components B and BN
would be less than significant.
Proposed project components Band BN would not result in any land use conflict with the City's
HMP because project components B and BN are not located within the designated Existing
Hardline Preserve Area of the City's HMP. Therefore, project level impacts associated with
components B and BN would be less than significant.
2.2 AGRICULTURAL RESOURCES
2.2.1 Program Level
Finding: Implementation of the DMP Update would not result in program level impacts to
agricultural resources associated with the Significance Criteria discussed in Section 4.2.2 of the
Final EIR. Specifically, the DMP Update components would not:
CEQA Findings of Fact 13 January 16, 2008
EIR 04-02 Carlsbad Drainage Master Plan Update
Findings of Fact
• convert Prime Farmland, Farmland of Statewide Importance, Unique Farmland, or
Farmland of Local Importance, as shown on the maps prepared pursuant to the Farmland
Mapping and Monitoring Program (i.e., Important Farmland), to nonagricultural use;
• conflict with existing General Plan policies, zoning for agricultural use, or a Williamson
Act contract; or
• involve other changes in the existing environment, which, due to their location or nature,
could result in conversion of agricultural land uses to nonagricultural use.
Facts in Support: Proposed DMP Update components would not result in the conversion of
Prime Farmland, Farmland of Statewide Importance, Unique Farmland, or Farmland of Local
Importance to nopagricultural use nor conflict with existing General Plan policies related to
agricultural land because proposed components would occur within existing drainage channels or
involve rehabilitation/replacement of existing drainage facilities and would not affect agricultural
land resources or activities. Additionally, the proposed DMP Update components would not
conflict with a Williamson Act Contract or zoning for agricultural use because no components of
the DMP Update are proposed within Williamson Act contract lands or areas zoned for
agricultural use. Therefore, program level impacts associated with agricultural resources would
be less than significant. Tables 4.2-2 and 4.2-3 of the Final EIR provide a detailed analysis of
impacts to agricultural resources.
2.2.2 Operation and Maintenance
Finding: Implementation of proposed operation and maintenance activities would not result in
program level impacts to agricultural resources associated with the Significance Criteria
discussed in Section 4.2.2 of the Final EIR and restated above in Section 2.2.2.
Facts in Support: Proposed operation and maintenance activities would not result in the
conversion of designated Important Farmland or the conversion of existing agricultural uses to
nonagricultural uses because operation and maintenance activities would be conducted primarily
within existing drainage facilities and would not involve the construction of new structures on
existing agricultural land or Important Farmlands Likewise, proposed operation and
maintenance activities would not adversely affect areas currently zoned for agricultural use or
under a Williamson Act contract. Therefore, potential impacts to agricultural resources from
operation and maintenance activities would be less than significant.
2.2.3 Project Level
Finding: Implementation of proposed project components B and BN would not result in impacts
to agricultural resources associated with the Significance Criteria discussed in Section 4.2.2 of
the Final EIR and restated above in Section 2.2.2.
Facts in Support: Proposed project components B and BN would not result in impacts to
agricultural resources because none of the land within the project component boundaries is
designated as Important Farmland. Likewise, none of the land within the project limits is zoned
for agricultural use or included in a Williamson Act contract. Therefore, project level PLDA and
CEQA Findings of Fact 14 January 16, 2008
EIR 04-02 Carlsbad Drainage Master Plan Update
Findings of Fact
non-PLDA components would not adversely affect agricultural activities or resources, or conflict
with General Plan policies related to agricultural land use. Potential impacts would be less than
significant.
2.3 VISUAL RESOURCES
2.3.1 Program Level
Finding: Implementation of the DMP Update would not result in program level impacts to visual
resources associated with the Significance Criteria discussed in Section 4.3.2 of the Final EIR.
Specifically, the DMP Update components would not:
• substantially degrade the existing visual character or quality of the site and its
surroundings; or
• create a new source of substantial light and glare, which would adversely affect daytime
or nighttime views in the area.
Facts in Support: Proposed DMP Update components would not substantially degrade the visual
character of the city because proposed DMP Update components primarily involve construction,
replacement, and improvement of existing facilities within drainages located at or below grade
within or adjacent to existing road right-of-way or in developed/disturbed areas. The DMP
Update would not significantly change the existing quality of the overall visual character of the
city. Additionally, design features/methods and construction measures have been incorporated
into the project design that result in the avoidance of potential visual impacts. These measures
are discussed in Section 2.1 above and detailed in Table 3-6 of the Final EIR. For example,
proposed bridge structure modification and replacement (e.g., PLDA component Cl) and
potential staging areas and access roads during construction activities for some project
components (e.g., PLDA components AFA, AFB, BQ, C, and DH) would involve activities
within visible areas. These areas are required to be relandscaped to preconstruction conditions
(to the extent feasible) after project completion. Therefore, program level impacts relating to the
substantial degradation of existing visual character or quality would be less than significant.
Proposed DMP Update components would not create a new source of substantial light or glare
because design features/methods and construction measures incorporated into the project design
require that nighttime construction lighting be shielded or directed away from residential areas.
Additionally, there are no permanent lighting features or reflective materials proposed by the
DMP Update that would create a new permanent source of light or glare. Therefore, program
level impacts resulting from new sources of substantial light and glare would be less than
significant.
2.3.2 Operation and Maintenance
Finding: Implementation of proposed operation and maintenance activities would not result in
impacts to visual resources associated with the Significance Criteria discussed in Section 4.3.2 of
the Final EIR and restated above in Section 2.3.1.
CEQA Findings of Fact 15 January 16, 2008
EIR 04-02 Carlsbad Drainage Master Plan Update
Findings of Fact
Facts in Support: Proposed operation and maintenance activities would not substantially degrade
the existing visual character of the site or create a new source of substantial light and glare
because operation and maintenance activities would be periodic and temporary and would be
restricted to existing facilities and maintenance of the drainage purposes of those facilities. If
construction were required during maintenance of a specific facility, visual impacts from
construction activity would be periodic and temporary, and staging areas and equipment storage
would be located in existing right-of-way or other disturbed/developed areas. Therefore,
potential impacts to visual resources from operation and maintenance activities would be less
than significant.
2.3.3 Project Level
Finding: Implementation of proposed project components B and BN would not result in impacts
to visual resources associated with the Significance Criteria discussed in section 4.3.2 of the
Final EIR and restated above in Section 2.3.1.
Facts in Support: Proposed PLDA project components B and BN include dredging and
improvements in Agua Hedionda and Calavera creeks. These components would not
significantly degrade the existing visual character or quality because the visibility of the
proposed staging area would be a temporary impact to the existing visual character. No other
activities associated with the PLDA project components are expected to affect the scenic quality
of the area. Adopted project design measures as discussed in Section 2.1 above and detailed in
Table 3-6 of the Final EIR require relandscaping of areas where vegetation would be removed.
Overall, the improvements to Agua Hedionda and Calavera creeks are anticipated to provide an
overall visual enhancement. Therefore, project level impacts to visual resources associated with
PLDA project components B and BN would be less than significant.
Proposed PLDA project components B and BN would not create any new source of substantial
light and glare because dredging and construction activities would occur during daylight hours
and neither project component would result in the construction of any permanent source of light
or glare. Therefore, project level impacts resulting from new sources of substantial light and
glare would be less than significant.
Proposed non-PLDA project components B and BN include long-term channel maintenance in
Aqua Hedionda and Calavera creeks. These components would not significantly degrade the
existing visual character or quality because activities associated with channel maintenance would
occur periodically within existing drainage channels. If necessary, construction staging and
storage areas would be located in existing right-of-way or disturbed areas. Therefore, project
level impacts to visual resources associated with non-PLDA project components B and BN
would be less than significant.
Proposed non-PLDA project components B and BN would not create any new source of
substantial light and glare because long-term maintenance activities would occur during daylight
hours and would not require the construction of a new permanent lighting source or utilize
reflective materials. Therefore, project level impacts resulting from new sources of substantial
light and glare would be less than significant.

Findings of Fact
2.4 TRANSPORTATION/CIRCULATION
2.4.1 Program Level
Finding: Implementation of the DMP Update would not result in program level
transportation/circulation impacts associated with the Significance Criteria discussed in Section
4.4.2 ofthe Final EIR. Specifically, the DMP Update components would not:
• cause an increase in traffic, which is substantial in relation to the existing traffic load and
capacity of the street system (i.e., result in a substantial increase in either the number of
vehicle trips, the volume to capacity ratio on roads, or congestion at intersections);
• exceed, either individually or cumulatively, a level of service (LOS) standard established
by the County congestion management agency and the City's Growth Management
Program for designated roads or highways;
• result in inadequate emergency access; or
• result in insufficient parking capacity.
Facts in Support: Proposed DMP Update components would not increase traffic in relation to the
existing traffic load and street system capacity because the nature of the drainage improvements
proposed as part of the PLDA component would not generate traffic. Where construction of the
PLDA components could result in short-term traffic impacts due to the installation or
replacement of facilities within existing roadways, standard construction practices and
implementation of the required traffic control measures in the traffic control plans would avoid
traffic-related impacts due to lane closures. Therefore, program level impacts relating to
increased traffic would be less than significant.
Proposed DMP Update components would not exceed LOS standards. Although PLDA projects
could result in the generation of increased truck traffic during construction, the traffic is not
expected to exceed 200 peak hour trips per day or increase traffic on roadways to a level that
would degrade LOS at intersections or on roadway segments. DMP Update components would
not generate traffic in the long term; therefore, LOS for city streets would not be adversely
affected. Therefore, program level impacts relating to increased LOS would be less than
significant.
Proposed DMP Update components would not result in safety hazards from inadequate
emergency access because a detailed traffic control plan would be prepared for the construction
of both PLDA and non-PLDA projects during project specific environmental review. The traffic
control plan would include signage and flaggers, and other warning devices to allow heavy
equipment on roadways, and would provide adequate measures to ensure public safety of
motorists and pedestrians located near proposed construction areas. Through implementation of
these measures, potential program level impacts associated with emergency access would be less
than significant.
CEQA Findings of Fact 17 January 16, 2008
EIR 04-02 Carlsbad Drainage Master Plan Update
Findings of Fact
2.4.2 Operation and Maintenance
Finding: Implementation of proposed operation and maintenance activities would not result in
transportation/circulation impacts associated with the Significance Criteria discussed in Section
4.4.2 of the Final EIR and restated above in Section 2.4.1.
Facts in Support: Proposed DMP Update components would not result in traffic, access, or
parking impacts because operation and maintenance activities would not take place directly in
roadways or interfere with normal circulation. To avoid potential impacts resulting from
roadway, bridge, and culvert maintenance, the traffic control measures discussed above would be
implemented. Operation and maintenance activities would not generate traffic or adversely
affect transportation/circulation in the long term. Therefore, traffic impacts associated with
operation and maintenance activities would be less than significant.
2.4.3 Project Level
Finding: Implementation of proposed project components B and BN would not result in
transportation/circulation impacts associated with the Significance Criteria discussed in Section
4.4.2 ofthe Final EIR and restated above in Section 2.4.1.
Facts in Support: Project components B and BN would not result in an increase in traffic
because ingress and egress ofPLDA and non-PLDA project construction traffic would be subject
to a traffic control plan, including measures such as notices, signage, flaggers, and other warning
devices to control heavy equipment traffic and direct pedestrians to safe crossings. Details of
these project design measures are found in Table 3-6 of the Final EIR. Should the City select to
dispose of dredge material at an off-site location, as described as Option 2 in Section 3.4.3 of the
Final EIR, the project would require a City Haul Route Permit and haul routes would be
consistent with the City's approved truck haul route map. Project components Band BN would
not generate traffic or adversely affect transportation/circulation in the long term. Therefore,
project level traffic impacts would be less than significant.
Project components B and BN would not exceed any LOS standards because trip generation for
removal of channel spoils is estimated to average 60 average daily trips. This number of trips
would not result in a substantial increase in local traffic, or substantial degradation of segment or
intersection LOS. Therefore, project level impacts associated with a decrease in roadway or road
segment LOS would be less than significant. Project components B and BN would not interfere
with emergency access measures because emergency access to and from the Rancho Carlsbad
community and surrounding land uses would be maintained during construction of PLDA
components B and BN. Likewise, traffic control measures discussed above would be required
during construction activity. Therefore, project level impacts associated with emergency access
would be less than significant.
CEQA Findings of Fact 18 January 16, 2008
EIR 04-02 Carlsbad Drainage Master Plan Update
Findings of Fact
2.5 NOISE (PROJECT LEVEL)
Finding: Implementation of proposed project components B and BN would not result in noise
impacts associated with the Significance Criteria discussed in Section 4.6.2 of the Final EIR.
Specifically, the DMP Update components would not:
• expose persons within 50 feet of the project to generation of groundborne vibration in
excess of0.2 inches per second (in/sec) peak particle velocity (ppv);
• result in increased nighttime ambient noise levels;
• result in noise levels of more than 75 dBA (A-weighted decibels) equivalent noise level
(Leq) (or above ambient levels, if above 75 dBA Leq) over a period of more than
3 consecutive days; or
• expose people residing or working in the project area to excessive noise levels (for a
project located within an airport land use plan or, where such a plan has not been
adopted, within 2 miles of a public airport or public use airport).
Facts in Support: PLDA project components Band BN would not expose people within 50 feet
of the project to groundbourne vibration because temporary construction-related vibration at the
nearest receptors would be anticipated to be less than 0.06 in/sec ppv and would likely be less
than the level of perception. Groundbourne vibration caused by non-PLDA components is
anticipated to be even less. Therefore, project level impacts associated with groundbourne
vibration would be temporary and less than significant.
Both PLDA and non-PLDA project components B and BN would not result in increased
nighttime ambient noise levels because temporary construction activities would only occur
during daylight hours, as permitted by the City's noise ordinance. Therefore, project level
impacts associated with nighttime noise levels would be less than significant. PLDA project
components Band BN would not result in noise levels of more than 75 dBA Leq over a period of
more than 3 consecutive days. Although short-term noise levels at homes within 50 feet of
construction would exceed 75 dBA, and 1-hour average noise levels would be likely to exceed
75 dBA, the duration of this activity at any residence is anticipated to generally be less than 3
consecutive days. Exposure to vibrations for non-PLDA project components B and BN is
anticipated to be less than significant. Therefore, project level impacts associated with noise
exposure over 75 dBA would be temporary and less than significant.
2.6 AIR QUALITY
2.6.1 Program Level
Finding: Implementation of the DMP Update would not result in program level impacts to air
quality associated with the Significance Criteria discussed in Section 4.4.2 of the Final EIR.
Specifically, the DMP Update components would not:
CEQA Findings of Fact 19 January 16, 2008
EIR 04-02 Carlsbad Drainage Master Plan Update
Findings of Fact
• conflict with or obstruct implementation of the Regional Air Quality Strategy (RAQS);
• violate the National Ambient Air Quality Standards (NAAQS) or California Ambient Air
Quality Standards (CAAQS) or contribute substantially to an existing or projected air
quality violation;
• violate thresholds established by the U.S. Environmental Protection Agency (USEPA), as
shown in Table 4.5-5 ofthe Final EIR;
• result in a cumulatively considerable net increase of any criteria pollutant for which the
project region is in nonattainment under an applicable federal or state ambient air quality
standard (including releasing emissions that exceed quantitative thresholds for ozone
precursors);
• expose sensitive receptors to substantial pollutant concentrations; or
• expose sensitive receptors to objectionable odors for more than a 1-week period.
Facts in Support: The DMP Update components would not result in gaseous or particulate
emissions that conflict with or violate a national or state air quality standard or threshold because
implementation of standard design and construction practices as described in Table 3-6 of the
Final EIR would require pollution control measures during construction. These measures
include water and dust control agents would be applied to active grading areas, unpaved surfaces,
and dirt stockpiles to prevent or suppress airborne particulates; trucks and equipment would not
idle for more than 15 minutes when not in service; and air filters and other pollution control
devices on construction equipment would be properly operated and maintained. Through these
measures temporary impacts associated with violations of air quality standards would be less
than significant.
The DMP Update components would not result in exposure to objectionable odors because the
release of odor from wet sediments or from paving activities would dissipate relatively rapidly
and would not be anticipated to be noticeable for more than I week. Therefore, temporary
program level impacts associated with objectionable odors would be less than significant.
2.6.2 Operation and Maintenance
Finding: Implementation of proposed operation and maintenance activities to air quality
associated with the DMP Update would not result in impacts associated with the Significance
Criteria discussed in Section 4.5.2 ofthe Final EIR and restated above in Section 2.6.1.
Facts in Support: Proposed operation and maintenance activities of the DMP Update components
would not result in gaseous or particulate emissions that conflict with or violate a national or
state air quality standard or threshold because operation and maintenance of both PLDA and
non-PLDA components require use of standard design and construction practices as described
above and detailed in Table 3-6 of the Final EIR. Through implementation of these project
CEQA Findings of Fact 20 January 16, 2008
EJR 04-02 Carlsbad Drainage Master Plan Update
Findings of Fact
design features/methods and construction practices, air quality impacts associated with operation
and maintenance activities would be less than significant.
2.6.3 Project Level
Finding: Implementation of project components B and BN would not result in impacts associated
with the Significance Criteria discussed in Section 4.5.2 of the Final EIR and restated above in
Section 2.6.1.
Facts in Support: Project components B and BN would not result in gaseous or particulate
emissions that conflict with existing attainment and maintenance plans, violate air quality
standards, or make a considerable contribution to the existing regional pollutant concentrations
because estimated air emissions resulting from implementation of PLDA project components B
and· BN were modeled and calculated using the general assumption that 30,000 cubic yards of
dredged and excavated materials would be hauled off-site .and project construction would last 4
to 6 months. The conclusion reached was that estimated project emissions would be less than the
threshold values used for assessment of conformity of federal projects to the state air quality
plans (details of the modeling and calculations are included in Section 4.5.3.3 ofthe Final EIR).
Therefore, project level impacts resulting from air quality emissions would be less than
significant.
PLDA project components B and BN would not result in exposure to objectionable odors for
more than a 1-week period. Although there would be a potential for odor emissions from the
dredging and removal of wet sediments from the creek channels, this would be limited to the
time required to remove the odorous materials or for the odor emissions to be minimized by
drying of the materials and would not last more than 1 week. Therefore, project level impacts
associated with objectionable odors would be less than significant.
Non-PLDA project components B and BN would not result in air quality impacts because the
intensity and duration of long-term maintenance activities would be less, and emissions would be
less than calculated for the PLDA construction activities. Therefore, potential project level air
quality impacts associated with non-PLDA components B and BN would be less than significant.
2. 7 RECREATION
2.7.1 Program Level
Finding: Implementation of the DMP Update would not result in program level impacts to
recreation associated with the Significance Criteria discussed in Section 4. 7.2 of the Final EIR.
Specifically, the DMP Update components would not:
• result in adverse impacts to recreational opportunities in the city.
Facts in Support: The DMP Update components would not result in adverse impacts to
recreational opportunities in the city because the project does not involve construction of or
improvements to existing or proposed recreational facilities. Existing neighborhood and regional
CEQA Findings of Fact 21 January 16, 2008
EIR 04-02 Carlsbad Drainage Master Plan Update
Findings of Fact
parks or other recreational facilities would not be affected by the DMP Update. There could be
temporary impacts on recreational uses within open space and parks during construction of DMP
Update components; however, these potential impacts would be short term, and alternative
recreational facilities within the city would remain available for use. Therefore, program level
impacts to recreational opportunities within the city would be less than significant.
2. 7.2 Operation and Maintenance
Finding: Implementation of proposed operation and maintenance activities would not result in
impacts to recreation associated with the Significance Criteria discussed in Section 4.7.2 of the
Final EIR and restated above in Section 2. 7 .1.
Facts in Support: Implementation of proposed operation and maintenance activities associated
with the DMP Update would not result in adverse impacts to recreational opportunities in the
city because these activities would not involve the construction of recreational components or
improvements to existing or proposed recreational facilities. Existing neighborhood and regional
parks or other recreational facilities would not be affected. There could be temporary impacts on
recreational uses within open space and parks during operation and maintenance activities;
however, these potential impacts would be short term, and alternative recreational facilities
within the city would remain available for use. Therefore, recreational impacts associated with
operation and maintenance activities would be less than significant.
2.7.3 Project Level
Finding: Implementation of proposed project components B and BN would not result in impacts
associated with the Significance Criteria discussed in Section 4.7.2 of the Final EIR and restated
above in Section 2. 7 .1.
Facts in Support: Implementation of project components B and BN would not result in adverse
recreational opportunities in the city because neither PLDA nor non-PLDA components parts
would involve the construction or expansion of recreational facilities. Further, Use of existing
recreation facilities within the Rancho Carlsbad residential community would not be impacted by
implementation of either component B or BN. Therefore, project level recreational impacts
would be less than significant.
2.8 GEOLOGY/SOILS
2.8.1 Program Level
Finding: Implementation of the DMP Update would not result in program level impacts to
geology/soils associated with the Significance Criteria discussed in Section 4.8.2 of the Final
EIR. Specifically, the DMP Update components would not:
• expose people or structures to potential substantial adverse effects, including the risk of
loss, injury, or death involving:
CEQA Findings of Fact 22 January 16, 2008
EIR 04-02 Carlsbad Drainage Master Plan Update
Findings of Fact
o rupture of a known earthquake fault, as delineated on the most recent Alquist-Priolo
Earthquake Fault Zoning Map issued by the State Geologist for the area or based on
other substantial evidence of a known fault,
o strong seismic ground shaking,
o seismic-related ground failure, including liquefaction, or
o landslides;
• result in substantial soil erosion or the loss of topsoil;
• be located on a geologic unit or soil that is unstable, or that would become unstable as a
result of the project, and potentially result in on-or off-site landslide, lateral spreading,
subsidence, liquefaction, or collapse; or
• be located on expansive soils, as defined in the 1997 Uniform Building Code, creating
substantial risks to life or property; or
• result in the loss of availability of a locally important mineral resource.
Facts in Support: The DMP Update components would not result in the exposure of people or
structures to seismic, fault-related hazards, liquefaction, or landslides because, although the
proposed DMP Update components may potentially be subject to local seismic activity,
geotechnical investigations would be required prior to design of each component to identify
issues related to faults and seismic hazards and to develop appropriate design features to address
potential issues. Additionally, the City of Carlsbad Building Code and the Uniform Building
Code require project design measures be incorporated into project component design to minimize
the threat of such damage. Therefore, program level impacts associated with fault and seismic
activity would be less than significant.
The DMP Update components would not result in impacts due to unstable or expansive soils.
Although construction activity of components could result in potential hazards resulting from
expansive or unstable soils and rock conditions, a geotechnical investigation would be required
prior to the commencement of individual projects involving excavation, grading, or construction
of new structures. Likewise, the DMP Update components would not result in impacts from
substantial soil erosion because all construction would be performed in accordance with the
requirements of the City's Grading Ordinance, which requires the control of erosion during
construction and the stabilization of all disturbed surfaces upon completion of construction.
Therefore, program level impacts associated with expansive and unstable soil or soil erosion
would be less than significant.
The DMP Update components would not result in the loss of availability of a locally important
mineral resource because extraction of mineral resources is not proposed as part of the project.
Therefore, no program level impacts related to the loss of availability of a locally important
CEQA Findings of Fact 23 January 16, 2008
EIR 04-02 Carlsbad Drainage Master Plan Update
Findings of Fact
mineral resource recovery site are anticipated from implementation of proposed DMP Update
project components.
2.8.2 Operation and Maintenance
Finding: Implementation of proposed operation and maintenance activities would not result in
impacts to geology/soils associated with the Significance Criteria discussed in Section 4.8.2 of
the Final EIR and restated above in Section 2.8.1.
Facts in Support: Implementation of proposed operation and maintenance activities associated
with the DMP Update would not result in impacts to soils or seismic activity because site-
specific geotechnical analysis would be conducted for proposed PLDA and non-PLDA
components and site-specific remediation measures would be incorporated into facility project
design. Therefore, impacts to soils or seismic activity from operation and maintenance activities
would be less than significant.
Implementation of proposed operation and maintenance activities associated with the DMP
Update would not result in impacts from substantial soil erosion. Although some operation and
maintenance activities within natural channels could lead to damage from accelerated erosion, all
operation and maintenance would be performed in accordance with the requirements of the
City's Grading Ordinance, which requires the control of erosion during construction and the
stabilization of all disturbed surfaces upon completion of construction. Due to conformance with
the City's ordinance, erosion-related impacts from operation and maintenance activities would be
less than significant.
2.8.3 Project Level
Finding: Implementation of proposed project components B and BN would not result in impacts
to geology/soils associated with the Significance Criteria discussed in Section 4.8.2 of the Final
EIR and restated above in Section 2.8.1.
Facts in Support: Implementation of both PLDA and non-PLDA proposed project components B
and BN would not expose people or structures to geologic hazards because a geotechnical
evaluation found no evidence of faulting within the project limits. Although the project area
could experience seismic activity, the requirements of the City Building Code and the 2001
Uniform Building Code would be implemented as part of project level design to minimize the
threat of construction damage associated with seismic activity. Therefore, project level impacts
associated with geologic hazards would be less than significant.
Implementation of both PLDA and non-PLDA proposed project components B and BN would
not result in impacts due to erosion or unstable or expansive soils. Although the project would
involve bank and channel excavation and installation of drop structures, drains, and an access
road where expansive soils potentially occur, design of the project components would
incorporate Best Management Practices (BMPs) and erosion-prevention measures to address
issues related to expansive soils and stabilize the banks of the creeks. These BMPs are detailed
CEQA Findings of Fact 24 January 16, 2008
EIR 04-02 Carlsbad Drainage Master Plan Update
Findings of Fact
in Section 4.8.3.3 ofthe Final EIR. Through implementation of the BMPs, project level impacts
associated with erosion or unstable or expansive soils would be less than significant.
Implementation of both PLDA and non-PLDA project components B and BN would not result in
the loss of availability of a locally important mineral resource because the projects do not include
extraction of mineral resources. Additionally, no mineral resources recovery sites are designated
within the city, and no impacts related to loss of availability of a locally important mineral
resource recovery site are anticipated.
2.9 HYDROLOGY/WATER QUALITY
2.9.1 Program Level
Finding: Implementation of the DMP Update would not result in program level impacts to
hydrology/water quality associated with the Significance Criteria discussed in Section 4.9.2 of
the Final EIR. Specifically, the DMP Update components would not:
• violate federal, state, or local water quality standards or waste discharge requirements;
• alter the existing drainage pattern of flow of the area, including through the alteration of
the course of a stream or river, in a manner that would result in adverse impacts from
erosion, siltation, or flooding on-or off-site;
• create or contribute runoff water that would exceed the capacity of existing or planned
storm water drainage systems or provide substantial additional sources of polluted runoff;
• otherwise adversely impact water quality;
• place housing or other structures within a 1 00-year flood hazard area as mapped on a
Federal Flood Hazard Boundary or FIRM or other flood delineation map, that would
impede or redirect flows; or
• expose people or structures to a significant risk of loss, InJUry, or death involving
flooding.
Facts in Support: The DMP Update components would not result in violations of water quality
standards or waste discharge requirements, create or contribute an exceedance of storm water
runoff, or adversely impact water quality. Although temporary impacts could occur during
construction activities, a Storm Water Pollution Prevention Plan (SWPPP), as required by the
State Water Resources Control Board, will be prepared for project components resulting in soil
disturbance greater than or equal to 1 acre. The SWPPP will identify BMPs that will help reduce
impacts related to construction activities and postconstruction activities on storm water quality.
Details of proposed BMPs are included as project design measures in Table 3.6 and Section
4.9.3.1 of the Final EIR. In addition, under the San Diego County Municipal Permit, compliance
with the City's storm water management requirements includes preparation of a Water Quality
Technical Report (WQTR), which would minimize any impact of proposed projects on storm
CEQA Findings of Fact 25 January 16, 2008
EIR 04-02 Carlsbad Drainage Master Plan Update
Findings of Fact
water quality, regardless of project size. Through implementation of the BMPs identified in the
storm water management documents, program level impacts associated with hydrology/water
quality will be less than significant.
2.9.2 Operation and Maintenance
Finding: Implementation of proposed operation and maintenance activities would not result in
impacts to hydrology/water quality associated with the Significance Criteria discussed in Section
4.9.2 ofthe Final EIR and restated above in Section 2.9.1.
Facts in Support: Implementation of proposed operation and maintenance activities associated
with the DMP Update would not result in violations of water quality standards or waste
discharge requirements; create or contribute an exceedance of storm water runoff; or adversely
impact water quality because the spill contingency plan and construction measures, including a
SWPPP or WQTR, as appropriate, are identified as project design measures in Table 3-6 of the
Final EIR. Through implementation of the project design measures, including enforcement of
BMPs identified in the storm water management documents, hydrology/water quality impacts
associated with operation and maintenance activities will be less than significant.
2.9.3 Project Level
Finding: Implementation of proposed project components B and BN would not result in impacts
to hydrology/water quality associated with the Significance Criteria discussed in Section 4.9.2 of
the Final EIR and restated above in Section 2.9.1.
Facts in Support: Implementation of proposed project components B and BN would not result in
violations of water quality standards or waste discharge requirements, create or contribute an
exceedance of storm water runoff, or adversely impact water quality. Although the projects
propose dredging and construction activities that could potentially degrade water quality in the
creeks, project components B and BN would be required to incorporate BMPs into the project
design, which would be part of the required SWPPP, as specified in Table 3-6 of the Final EIR.
Implementation of the SWPPP would avoid potential impacts. Therefore, project level
hydrology/water quality impacts would be less than significant.
2.10 CULTURAL RESOURCES (PROJECT LEVEL)
Finding: Implementation of proposed project components B and BN would not result in impacts
to cultural resources associated with the Significance Criteria discussed in Section 4.11.2 of the
Final EIR. Specifically, project components Band BN would not:
• cause a substantial adverse change in the significance of a historical or archaeological
resource as defined in Section 15064.5; or
• disturb any human remains, including those interred outside of formal cemeteries.
CEQA Findings ofF act 26 January 16, 2008
EIR 04-02 Carlsbad Drainage Master Plan Update
Findings of Fact
Facts in Support: Implementation of both PLDA and non-PLDA components B and BN would
not result in impacts to cultural resources because no cultural resources were identified during
the archival research or field survey within the proposed project areas.
Implementation of PLDA and non-PLDA components of proposed project components B and
BN would not result in the disturbance of human remains. Although the potential exists for
buried cultural deposits in areas adjacent to creek and river beds, none are expected to be
encountered during ground-disturbing activities associated with the dredging of Agua Hedionda
and Calavera creeks due to the level of previous disturbance in the area. Therefore, project level
impacts to cultural resources would be less than significant.
2.11 PALEONTOLOGICAL RESOURCES (PROJECT LEVEL)
Finding: Implementation of proposed project components B and BN would not result in impacts
to paleontological resources associated with the Significance Criteria discussed in Section 4.12.2
of the Final EIR. Specifically, project components Band BN would not:
• directly or indirectly destroy an identified sensitive paleontological resource or site or an
identified sensitive geologic feature.
Facts in Support: Implementation ofboth PLDA and non-PLDA components of proposed project
components B and BN would not result in impacts to paleontological resources because the
proposed project boundary for project components B and BN is located on Quaternary alluvial
deposits, which have a low to moderate potential to contain paleontological resources.
Additionally, the creeks were previously dredged and channelized during construction of the
Rancho Carlsbad residential community, as well as during subsequent emergency dredging.
Therefore, paleontological resources would not likely be destroyed as a result of conducting the
proposed dredging and improvements, and project level impacts would be less than significant.
2.12 CUMULATIVE (PROGRAM AND PROJECT LEVEL)
2.12.1 Land Use
Finding: Implementation of the DMP Update would not result in program or project level
cumulative impacts to land use.
Facts in Support: Implementation of the DMP Update would not result in significant land use
impacts. It is assumed that future development in the city would occur in a manner consistent
with the City's General Plan, Growth Management Plan, and other land use planning documents
and regulations. However, implementation ofthe DMP Update would not alter planned land use
conditions in the city beyond what is envisioned in the General Plan. Therefore, the DMP Update
would not contribute to climulative land use impacts in Carlsbad.
2.12.2 Agricultural Resources
Finding: Implementation of the DMP Update would not result in program or project level
cumulative impacts to agricultural resources.
CEQA Findings of Fact 27 January 16, 2008
EIR 04-02 Carlsbad Drainage Master Plan Update
Findings of Fact
Facts in Support: Implementation of the proposed DMP Update components would not result in
significant agricultural resource impacts. The proposed DMP Update components would not
involve the conversion of Important Farmlands or existing agricultural uses to nonagricultural
uses and would not conflict with any Williamson Act contracts in the City. Therefore the DMP
Update would not contribute to cumulative agricultural resource impacts.
2.12.3 Visual Resources
Finding: Implementation of the DMP Update would not result in program or project level
cumulative impacts to visual resources.
Facts in Support: Implementation of the proposed DMP Update components would not result in
significant impacts to visual resources. Many proposed components are located at or below
grade within or adjacent to the existing road right of way or in developed/disturbed areas. Visual
impacts during construction would be short-term and no permanent lighting would be necessary.
For this reason, the DMP Update would not contribute to cumulative impacts to visual resources.
2.12.4 Transportation/Circulation
Finding: Implementation of the DMP Update would not result in program or project level
cumulative impacts to transportation/circulation.
Facts in Support: Implementation of the proposed DMP Update components would not result in
impacts to transportation/circulation. Although project components could generate potential
cumulative short-term construction-related impacts, these would be minimized or avoided
through coordination and implementation of traffic control plans and encroachment permit
requirements at the time of construction. Through these measures, the DMP Update would not
cumulatively contribute to significant transportation/circulation impacts.
2.12.5 Noise
Finding: Implementation of the DMP Update would not result in program or project level
cumulative noise impacts.
Facts in Support: Implementation of the proposed DMP Update components would not result in
significant noise impacts. DMP Update components have the potential to generate short-term
noise impacts during construction and maintenance activities; however, the components would
not result in any long-term noise impacts. Potential localized impacts due to construction noise
are mitigated to a level of insignificant through required component compliance with standards
regarding acceptable levels of vibration caused by construction equipment and noise when
construction is within a specified distance of a sensitive receptor. Therefore, the DMP Update
would not result in a significant contribution to cumulative noise impacts.
2.12.6 Air Quality
Finding: Implementation of the DMP Update would not result in program or project level
cumulative air quality impacts.
CEQA Findings of Fact 28 January 16, 2008
EIR 04-02 Carlsbad Drainage Master Plan Update
Findings of Fact
Facts in Support: Implementation of the proposed DMP Update components would not result in
significant impacts to air quality. Temporary emissions generated from construction equipment
and fugitive dust during construction activities would be minimized by incorporation of the dust
control and construction emission control features included in Table 3-6 of the Final EIR.
Therefore, the DMP Update components would not result in a significant contribution to
cumulative air quality impacts.
2.12.7 Recreation
Finding: Implementation of the DMP Update would not result in program or project level
cumulative impacts to recreational resources.
Facts in Support: Implementation of the proposed DMP Update components would not result in
significant impacts to recreation. Impacts to existing facilities could be experienced during
component construction, but these impacts would be short term and alternative recreation
facilities within Carlsbad would remain available for use. Therefore, the DMP Update would not
contribute to cumulative impacts to recreation.
2.12.8 Geology/Soils
Finding: Implementation of the DMP Update would not result in program or project level
cumulative impacts to geology/soils.
Facts in Support: Implementation of the proposed DMP Update components would not result in
significant impacts to geology/soils. Geologic conditions in the region would essentially remain
the same regardless of implementation of the DMP Update, and geotechnical investigations would
be required prior to project construction. Therefore, the DMP Update would not contribute to
cumulative impacts related to geology/soils.
2.12.9 Hydrology/Water Quality
Finding: Implementation of the DMP Update would not result in program or project level
cumulative impacts to hydrology/water quality.
Facts in Support: Implementation of the proposed DMP Update components would not result in
significant hydrology/water quality impacts. The DMP Update would not substantially increase
the amount of impervious surfaces and would serve to improve overall flood control and storm
water conveyance in the City; components would also be required to comply with various water
quality control measures such as those outlined in Table 3-6 of the Final EIR. Therefore, the
project would not significantly contribute to cumulative hydrology/water quality impacts.
2.12.10 Cultural Resources
Finding: Implementation of the DMP Update would not result in program or project level
cumulative impacts to cultural resources.
CEQA Findings of Fact 29 January 16, 2008
EIR 04-02 Carlsbad Drainage Master Plan Update
Findings of Fact
Facts in Support: Implementation of the proposed DMP Update components would not result in
significant impacts to cultural resources based on the mitigation measures recommended in
Section 4.11 of the Final EIR. Further, project level components B and BN are not anticipated to
impact cultural resources. Therefore, the project would not result in a considerable contribution
to significant cumulative cultural resource impacts.
2.12.11 Paleontological Resources
Finding: Implementation of the DMP Update would not result in program or project level
cumulative impacts to paleontological resources.
Facts in Support: Implementation of the proposed DMP Update components would not result in
significant impacts to paleontological resources based on the mitigation measures recommended
in Section 4.12 of the Final EIR. Further, project level components B and BN are not anticipated
to impact paleontological resources. Therefore, the project would not result in a considerable
contribution to a significant cumulative paleontological resource impact.
3.0 FINDINGS REGARDING ENVIRONMENTAL IMPACTS DETERMINED TO
BE MITIGATED TO A LEVEL OF LESS THAN SIGNIFICANT
The Final EIR identifies certain mitigation measures that have been incorporated, in all
substantive respects, into the MMRP for the DMP Update. The City, as Lead Agency, will
incorporate the MMRP into the conditions of approval of the DMP Update.
The City finds, pursuant to CEQA Section 2108l(a)(l)-(2) and CEQA Guidelines Section
1509l(a)(l)-(2), that changes or alterations have been required in, or incorporated into, the
Project, which would avoid or substantially lessen the potentially significant effects in the
following environmental categories: (1) noise; (project level); (2) biological resources (program
and project level); (3) cultural resources (program level); and, (4) paleontological resources
(program level).
The City finds that the potentially significant effects in the environmental categories specified
above have been mitigated to a level that is less than significant after implementation of
mitigation measures identified in the Final EIR and incorporated into the MMRP. The impacts,
which have been reduced to a less than significant level with mitigation, together with the basis
for such determination, are set forth below.
3.1 NOISE (PROGRAM LEVEL)
3.1.1 Potentially Significant Impacts
The DMP Update has the potential to result in the following potentially significant program level
noise impacts:
• There would be a potentially significant noise impact if a proposed DMP Update
component would require the use of heavy construction equipment, generating noise of
75 dBA or greater within 50 feet of a sensitive receptor for a period of longer than 3 days,
CEQA Findings of Fact 30 January 16, 2008
EIR 04-02 Carlsbad Drainage Master Plan Update
Findings of Fact
or if a proposed DMP Update project component would require work to be done after
sunset or before 7:00a.m., excluding holidays. (Noise-1)
• There would be a potentially significant vibration impact if a proposed DMP Update
component would require the use of pile drivers, generating a vibration of 0.2 in/sec or
greater at a sensitive receptor. (Noise-2)
Operation and maintenance activities identified in the DMP Update have the potential to result in
potentially significant noise impact Noise-1, stated above.
3.1.2 Finding
Mitigation measures have been identified in the Final EIR that mitigate or avoid potentially
significant program level noise impacts resulting from implementation of the DMP Update.
3.1.3 Mitigation Measures
The Final EIR found that the above potentially significant effects relating to program level noise
impacts would be mitigated to a level of less than significant through implementation of the
following mitigation measures:
Noise-1
Noise-2
If a proposed project component would require the use of construction equipment
that may generate noise of 75 dBA or greater within 50 feet of a sensitive receptor
for a period of longer than 3 days, or would require work to be done between
sunset and 7:00 a.m., as permitted by Municipal Code Section 8.48.020,
preparation and implementation of a project level noise evaluation shall be
required. The evaluation shall assess potential noise levels and require the
implementation of appropriate noise attenuation measures to reduce potential
noise impacts to less than 75 dBA Leq during the daytime or to 60 dBA Leq at
nighttime. The noise evaluation shall consider the use of temporary noise walls,
noise blankets, noise-reducing enclosures for individual pieces of equipment, and
engines with special mufflers as potential noise attenuation measures. Monitoring
shall be required to demonstrate the effectiveness of the project-specific measures
to reduce noise levels to this limit. If monitoring results indicate that the
measures are not reducing noise to acceptable levels, work will cease until further
environmental analysis is performed that recommends additional noise attenuation
measures. For emergency projects as defined in Municipal Code Section
8.48.020(A), the requirement for evaluation, monitoring, and potential additional
mitigation measures shall be performed if determined feasible by the City
Engineer.
If a proposed project component would require the use of pile drivers, preparation
and implementation of a project level vibration evaluation shall be required. The
evaluation shall consider the potential vibration levels associated with project
construction at the nearest structure locations. The analysis shall demonstrate that
CEQA Findings of Fact 31 January 16, 2008
EIR 04-02 Carlsbad Drainage Master Plan Update
Findings of Fact
vibration levels at those structures remain below 0.2 in/sec, or a different
construction technique resulting in vibration less than 0.2 in/sec shall be required.
3.1.4 Facts in Support
Implementation of Mitigation Measure Noise-1 will reduce potentially significant noise impacts
associated with the use of heavy construction equipment because preconstruction noise
assessments will verify that appropriate noise attenuation measures are tailored for each DMP
Update project component to reduce potential significant impacts to less than significant.
Implementation of Mitigation Measure Noise-2 will reduce potentially significant noise impacts
associated with vibration impacts because preconstruction vibration evaluations will verify that
appropriate measures are tailored for each DMP Update project component to reduce potential
significant impacts to less than significant. Implementation of Mitigation Measures Noise-1 and
Nosie-2 will reduce potentially significant noise impacts to a level of less than significant.
3.2 BIOLOGICAL RESOURCES (PROGRAM AND PROJECT LEVEL)
3.2.1 Potentially Significant Impacts (Program Level)
The DMP Update and operation and maintenance activities have the potential to result in the
following potentially significant program level and cumulative biological resource impacts:
• Per the City's HMP, implementation of proposed DMP Update components could result
in long-term impacts if sensitive species or habitats are permanently destroyed or
degraded. This would also result in a cumulative impact to biological resources. (Bio-I)
• Long-term or permanent impacts could result from loss of sensitive habitats within the
Coastal Zone. This would contribute to the regional loss of sensitive habitats, resulting in
a cumulative impact. (Bio-2)
• The loss of state and/or federally listed plant species is considered a significant impact.
The loss of sensitive plant species at a regional level would contribute to a cumulative
impact. (Bio-3)
• Drainage facility improvements that result in substantial vegetation clearing or impede
wildlife movement within Core Areas and linkages would result in a significant impact.
(Bio-4)
3.2.2 Finding
Mitigation measures have been identified in the Final EIR that mitigate or avoid potentially
significant program level and cumulative impacts to biological resources resulting from
implementation of the DMP Update.
3.2.3 Mitigation Measures
CEQA Findings of Fact 32 January 16, 2008
EIR 04-02 Carlsbad Drainage Master Plan Update
Findings of Fact
The Final EIR found that the above significant effects relating to biological impacts would be
mitigated to a level considered less than significant through implementation of the following
mitigation measures. Implementation of Mitigation Measures Bio 1-a through Bio 1-d would be
required for DMP Update components that would impact sensitive HMP habitats and would
reduce direct and cumulative impacts to below a level of significance. Note that the descriptions
of Type A through F habitats are per Table 11 of the City's HMP. Avoidance and on-site
mitigation are the priority. Future project level environmental review for DMP Update
components that would impact biological resources would be provided to the Wildlife Agencies
for review to verify consistency with the City's HMP.

For impacts to Type A habitats (coastal salt marsh, alkali marsh, freshwater
marsh, estuarine, salt pan/mudflats, riparian forest, riparian woodland, riparian
scrub, disturbed wetlands, flood channel, fresh water, Engelmann oak woodland,
coast live oak woodland) a goal of no net loss of habitat value or function shall be
met. Habitat replacement ratios and the specific location of mitigation lands shall
be determined in consultation with the USFWS, USACE, and CDFG as
appropriate in accordance with the requirements of the federal Clean Water Act
(CW A), federal wetland policies, and the California Fish and Game Code. All
mitigation lands for impacts to riparian and wetland habitats shall be in the City or
Multiple Habitat Conservation Program (MHCP) plan area, at a ratio to be
determined by the applicable Resource Agencies at the time of project permitting.
Impacts to Type B habitats (beach, southern coastal bluff scrub, maritime
succulent scrub, southern maritime chaparral, and native grass) shall be mitigated
at a 3: 1 ratio, or at an appropriate ratio based on habitat quality and quantity as
determined in coordination with the applicable Resource Agencies at the time of
project permitting.
Impacts to Type C habitats (California gnatcatcher-occupied coastal sage scrub)
shall be mitigated at a 2:1 ratio, or at an appropriate ratio based on habitat quality
and quantity as determined in coordination with the applicable Resource Agencies
at the time of project permitting.
Impacts to Type D (unoccupied coastal sage scrub, coastal sage/chaparral mix,
chaparral), Type E (annual, nonnative grassland), and Type F (disturbed lands,
eucalyptus, agricultural lands) habitats are not subject to the fee payment.
Instead, these types of impacts will be mitigated at the Lake Calavera Mitigation
Bank, per the ratios included in Table ·11 of the HMP. An appropriate mitigation
ratio would be determined based on habitat quality and quantity as determined in
coordination with the applicable Resource Agencies at the time of project
permitting.
Prior to the first preconstruction meeting for each project component, the City
shall verify that the following statement is included in the construction
specifications: No clearing, grubbing, grading, or other construction activities
within occupied gnatcatcher habitat shall occur between March 1 and August 15,

the breeding season of the coastal California gnatcatcher (gnatcatcher). No
clearing, grubbing, grading, or other construction activities within or adjacent to
unoccupied habitat shall occur between March I and August I5, until the
requirements in Bio-I f and Bio-I g have been met to the satisfaction of the City:
A qualified biologist (possessing a valid Endangered Species Act Section
IO(a)(I)(a) Recovery Permit) shall survey appropriate habitat areas subject to
construction noise levels exceeding 60 dBA Leq for the presence of gnatcatcher.
Gnatcatcher surveys shall be conducted pursuant to USFWS protocol survey
guidelines a minimum of 4 weeks (within the breeding season) prior to
commencement of construction. If gnatcatchers are present, then the following
conditions must be met:
• Between March I and August I5, no construction activities shall occur
within any portion of the site where such activities would result in noise
levels exceeding 60 dBA Leq at the edge of occupied gnatcatcher habitat.
An analysis concluding that construction-generated noise would not
exceed 60 dBA Leq at the edge of occupied habitat must be completed by a
qualified acoustician (possessing current noise engineer license or
registration, with experience monitoring noise levels for listed wildlife
species) and approved by the City at least 2 weeks prior to commencement
of construction activities; OR
• At least 2 weeks prior to commencement of construction activities, and
under the direction of a qualified acoustician, noise attenuation measures
(e. g., berms, walls) shall be implemented to ensure that construction-
generated noise will not exceed 60 dBA Leq at the edge of occupied
gnatcatcher habitat. Concurrent with commencement of construction
activities and with implementation of necessary noise attenuation
measures, noise monitoring1 shall be conducted at the edge of occupied
habitat to ensure that construction-generated noise does not exceed
60 dBA Leq· If the noise attenuation measures implemented are
determined to be inadequate by the qualified acoustician or biologist, then
the associated construction activities shall cease until such time that
adequate noise attenuation is achieved or until the end of the breeding
season (August I5).
If gnatcatchers are not detected during the preconstniction survey within areas
that would be subject to construction noise levels exceeding 60 dBA Leq, the
qualified biologist shall submit substantial evidence to the City and applicable
Noise monitoring shall continue at least twice weekly on varying days, or more frequently depending on .the
construction activity, to verify that noise levels at the edge of occupied habitat are maintained below 60 dBA Leq
or to the ambient noise level if it already exceeds 60 dBA Leq· If not, other measures shall be implemented in
consultation with the biologist and the City, as necessary, to reduce construction-generated noise levels to below
60 dBA Leq or to the ambient noise level if it already exceeds 60 dBA Leq· Such measures may include, but are
not limited to, limitations on the placement of construction equipment and the simultaneous use of equipment.

adhered to as specified above.
• If this evidence concludes that no impacts to this species are anticipated,
no mitigation measures will be necessary.
Prior to the first preconstruction meeting for each project component, the City
shall verify that the following statement is included in the construction
specifications: No clearing, grubbing, grading, or other construction activities
shall occur within least Bell's vireo habitat shall occur between March 15 and
September 15 (least Bell's vireo breeding season) in occupied least Bell's vireo
habitat. No clearing, grubbing, grading, or other construction activities within or

and September 15 until the requirements in Bio-li and Bio-1j have been met to
the satisfaction of the City.
A qualified biologist shall survey those wetland areas that would be subject to
construction noise levels exceeding 60 dBA Leq for the presence of least Bell's
vireo. Least Bell's vireo surveys shall be conducted a minimum of 8 weeks
(within the breeding season) prior to commencement of construction. If least
Bell's vireos are present, then the following conditions must be met:
• Between March 15 and September 15, no construction activities shall
occur within any portion of the site where such activities would result in
noise levels exceeding 60 dB A Leq at the edge of occupied least Bell's
vireo habitat. An analysis showing that construction-generated noise
would not exceed 60 dBA Leq at the edge of occupied habitat must be
completed by a qualified acoustician (possessing current noise engineer

exceeding 60 dBA Leq, the qualified biologist shall provide evidence to the City
and applicable regulatory agencies demonstrating whether noise attenuation
measures (e.g., berms, walls) are necessary between March 15 and September 15
as follows:
• If this evidence indicates the potential is high for least Bell's vireo to be
present based on historical records or site conditions, then condition 1 i
shall be adhered to as specified above.
• If this evidence concludes that no impacts to this species are anticipated,
no mitigation measures would be necessary.
Prior to the first preconstruction meeting for each phase of the project component,
the City shall verify that the following statement is included in the construction
specifications: No clearing, grubbing, grading, or other construction activities
shall occur within occupied southwestern willow flycatcher habitat between May
1 and September 1 (southwestern willow flycatcher breeding season). No
clearing, grubbing, grading, or other construction activities within or adjacent to
unoccupied southwestern willow flycatcher habitat shall occur between May 1

Findings of Fact
Mitigation ratios shall be consistent with the provisions of the HMP and LCP.
For all projects affecting riparian and wetland habitat, habitat replacement ratios
and the specific location of mitigation lands shall be determined in consultation
with the USFWS, USACE, and CDFG as appropriate in accordance with the
requirements of the federal CWA, federal wetland policies, and the California
Fish and Game Code. For DMP Update components with unavoidable impacts,
the City shall either: (I) demonstrate that viable wetlands can be created at a
minimum ratio of I : 1 within close proximity of the impact area to replace the
wildlife function affected by the project; or (2) provide proof that wetland
creation credits at a minimum ratio of I :I have been purchased at a Wildlife
Agency approved bank. Consistent with the City's HMP, higher ratios will be
required for impacts to high-quality wetlands (e.g., occupied by listed or
otherwise sensitive species) and for wetlands within the Coastal Zone. For DMP
Update components where wetland creation will be necessary, construction shall
not be initiated until a viable wetland creation mitigation site with long-term value
is identified (and if necessary purchased by the City) and the wetland mitigation
plan is approved by the appropriate Resource Agencies. The wetland creation
shall not require impacts to sensitive wildlife or vegetation communities. All
mitigation lands for impacts to riparian and wetland habitats shall be in the City or
MHCP plan area as deemed appropriate by the Wildlife Agencies.
As needed, surveys for state and federally listed sensitive plant species shall be
conducted to complete a determination of suitable habitat presence prior to
implementation of DMP Update components. Surveys shall be conducted at a
time when sensitive plant species would be most observable.
At the project design stage for the DMP Update components located within key
Core Areas and linkages, design measures and restoration efforts shall be required
to maintain the viability of the wildlife corridors throughout Carlsbad.
3.2.4 Facts in Support
Implementation of Mitigation Measures Bio-la through Bio-ld will reduce potentially
significant impacts to sensitive habitat because they require replacement of disturbed habitat with
preserved habitat at ratios determined in consultation with the Resource Agencies. This measure
will verify that despite disturbance of habitat caused by development, sensitive habitat remains
viable throughout the city. Implementation of Mitigation Measures Bio-le through Bio-lm will
reduce potentially significant impacts to coastal California gnatcatcher (Polioptila californica),
least Bell's vireo (Vireo bellii pusillus), and southwestern willow flycatcher (Empidonax traillii
extimus) because they require the avoidance of breeding seasons, and preconstruction screening
of surrounding habitat to determine the existence of nesting birds. This will verify that
appropriate steps are taken to protect the species from noise generated by the nearby
construction.
CEQA Findings of Fact 38 January 16, 2008
EIR 04-02 Carlsbad Drainage Master Plan Update
Findings of Fact
Implementation of Mitigation Measure Bio-I n will reduce potentially significant impacts to
native fish because it requires preconstruction identification of such species in water bodies
potentially affected by construction activities to verify appropriate protective steps are taken
prior to in-stream activities.
Implementation of Mitigation Measure Bio-I o will reduce potentially significant impacts to
additional wildlife species through the requirement of preconstruction protocol surveys as
directed by the state and federal Wildlife Agencies. These surveys will identify whether any
species requiring protective measures are present within the project sites. Through
implementation of Mitigation Measure Bio-Io, potentially significant impacts to sensitive habitat
and species will be reduced to less than significant.
Implementation of Mitigation Measures Bio-2a and 2b will reduce potentially significant impacts
resulting from loss of sensitive habitats within the Coastal Zone because disturbed habitat shall
be replaced at ratios consistent with requirements of the City's HMP and determined in
consultation with the Wildlife Agencies. Wetland loss will require approval by the Resource
Agencies of a viable wetland creation mitigation site with long-terin value prior to initiation of
construction. This measure will verify the continued viability of coastal habitat through
preservation and restoration. Through implementation of Mitigation Measures Bio-2a and 2b,
potentially significant impacts to sensitive habitat within the Coastal Zone will be reduced to less
than significant.
Implementation of Mitigation Measures Bio-3 will reduce potentially significant impacts
resulting from loss of sensitive plant species because preconstruction surveys are required to
determine the existence of sensitive plants in the vicinity of each project so appropriate
protective steps can be taken. Through implementation of Mitigation Measures Bio-3,
potentially significant impacts to sensitive plants will be reduced to less than significant.
Implementation of Mitigation Measure Bio-4 will reduce potentially significant impacts resulting
from impeding wildlife movement within Core Areas and linkages because each component of
the DMP Update must be designed to preserve wildlife movement within the drainages.
Through implementation of Mitigation Measure Bio-4, potentially significant impacts associated
with wildlife movement will be reduced to less than significant.
3.2.5 Potentially Significant Impacts (Project Level)
DMP Update project components B and BN and have the potential to result in the following
project level potentially significant biological impacts:
• The loss of 0.08 acres of willow riparian forest is considered a significant and cumulative
impact and requires compensatory mitigation (i.e., creation, restoration, and/or
replacement of in-kind habitat). (Bio-5)
• Loss of wetland and riparian habitat within the Coastal Zone is considered a significant
and cumulative impact. (Bio-6)
CEQA Findings of Fact 39 January I 6, 2008

Findings of Fact
• Proposed dredging and improvements within Agua Hedionda Creek (area adjacent to
Cannon Road Bridge) have the potential to result in significant indirect impacts to least
Bell's vireo, southwestern willow flycatcher, and light-footed clapper rail. (Bio-7)
3.2.6 Finding
Mitigation measures have been identified in the Final EIR that mitigate or avoid potentially
significant impacts to biological resources resulting from implementation of the DMP Update
components B and BN.
3.2. 7 Mitigation
The Final EIR found that the above significant effects relating to project level biological impacts
would be mitigated to a level considered less than significant through implementation of the
following mitigation measures:
Bio-5
Bio-6
Bio-7a
Bio-7b
Bio-7c
Mitigation measures listed for Bio-la, and Bio-2a and 2b shall be implemented as
applicable to address project-specific vegetation impacts within Agua Hedionda
and Calavera creeks.
The project shall mitigate impacts to wetland and riparian habitat through on-site
restoration and/or off-site wetland and riparian habitat creation/restoration/
enhancement at a ratio to be determined in coordination with the applicable
Resource Agencies at the time of permitting, consistent with LCP and HMP
policies and provisions, as applicable. If adequate acreage to satisfy mitigation is
not available on-site and/or at the Lake Calavera Mitigation Bank, then alternative
mitigation credits may be purchased from the North County Mitigation Bank, or
other alternative sites deemed acceptable by the Resource Agencies.
If dredging and improvement activities cannot be conducted outside the breeding
season for sensitive wildlife species, then prior to commencement of construction
activities, a preconstruction survey shall be conducted by a qualified biologist to
determine presence/absence of nesting birds. If nesting birds are detected on-site,
vegetation removal shall be delayed until the chicks have fledged or the nest has
failed.
To address potential impacts to the light-footed clapper rail, a qualified biologist
shall survey the area and surrounding 500-foot buffer area for light-footed clapper
rails prior to implementation of dredging activities. There is no need to survey
the area upstream of El Camino Real since this area is void of suitable clapper rail
habitat (freshwater marsh). If clapper rails are detected in the project area, they
should be flushed, prior to the onset of any vegetation removal.
For potential indirect impacts to least Bell's vireo, Mitigation Measures Bio 1-h
through Bio 1-j shall be implemented, as applicable.

Findings of Fact
For potential indirect impacts to southwestern willow flycatcher, implementation
Mitigation Measures Bio-I k through Bio-I m shall be implemented, as applicable.
To discourage sensitive bird species from entering active construction areas
between El Camino Real and Cannon Road bridges, a physical barrier
(construction fence) shall be installed on the downstream side of Cannon Road
before dredging or vegetation removal commences. The barrier would be
removed once the construction activity has ceased on the south side of El Camino
Real.
3.2.8 Facts in Support
Implementation of Mitigation Measure Bio-5 will reduce potentially significant impacts resulting
from the loss of 0.08 acres of willow riparian forest because habitat replacement will be required
for the disturbed willow riparian forest at ratios determined in consultation with state and federal
Wildlife Agencies. Through implementation of Mitigation Measure Bio-5, potentially
significant impacts to 0.08 acres of willow riparian forest will be reduced to less than significant.
Implementation of Mitigation Measure Bio-6 will reduce potentially significant impacts resulting
from the loss of wetland and riparian habitat within the Coastal Zone because wetland habitat
restoration and creation are required for all impacts at ratios determined in coordination with the
applicable Resource Agencies. Through implementation of Mitigation Measure Bio-6,
potentially significant impacts to riparian habitat will be reduced to less than significant.
Implementation of Mitigation Measures Bio-7 a through Bio-7 e will reduce potentially significant
impacts resulting from the indirect impacts to least Bell's vireo, southwestern willow flycatcher,
and light-footed clapper rail because preconstruction surveys of the project areas will verify that
appropriate measures are taken prior to disturbance of vegetation. Through implementation of
Mitigation Measures Bio-7a through Bio-7e, potentially significant impacts to least Bell's vireo,
southwestern willow flycatcher, and light-footed clapper rail will be reduced to less than
significant.
3.3 CULTURAL RESOURCES (PROGRAM LEVEL)
3.3.1 Potentially Significant Impacts
The DMP Update has the potential to result in the following potentially significant program level
impacts to cultural resources:
• For those areas not adequately surveyed, as identified in Tables 4.Il-2 and 4.11-3 of the
Final EIR, roads traversing previously undisturbed areas or projects requiring surface
disturbance in undeveloped areas could potentially lead to significant impacts to surface
cultural deposits. (Cult-I)
• Ground-disturbing project activities or excavation into intact native soils could potentially
impact significant cultural resources that have not yet been discovered. (Cult-2)

3.3.2 Finding
Mitigation measures have been identified in the Final EIR that mitigate or avoid potentially
significant program level impacts to cultural resources resulting from implementation of the
DMP Update.
3.3.3 Mitigation Measures
The Final EIR found that the above significant effects relating to program level and operation
and maintenance activities would be mitigated to a level considered less than significant through
implementation of the following mitigation measures:
Cult-1 The following mitigation measures will be required if a proposed PLDA or non-
PLDA component is located in an undeveloped area that could potentially impact
significant cultural deposits, as indicated in Tables 4.11-2 and 4.11-3. In addition,
for any operation and maintenance activities that will require temporary
construction of an access road through previously undeveloped or undisturbed
areas, the following mitigation measures will be required prior to construction.
a) Preconstruction Requirements -Prior to the start of construction, a
pedestrian survey shall be conducted under the supervision of a qualified
archaeologist for previously undisturbed areas that have not been surveyed
or adequately surveyed (e.g., the area was surveyed with outdated or non-
protocol methods). The survey shall be conducted in parallel linear
transects spaced no farther than 10 meters apart in undeveloped areas.
1) Cultural resources, if found during the survey, shall be photographed,
mapped using a global positioning system (GPS), and recorded on the
appropriate California Department of Parks and Recreation forms
(DPR Form 523A/B). The forms shall be submitted to the South
Coastal Information Center (SCIC) for the assignment of Primary
numbers within 1 week of the survey.
2) Within 1 month of completion of the field survey, a draft letter report
or technical report shall be submitted to the City for review, whether
the survey is negative or positive. A final report shall be submitted
within 6 weeks of receipt of the City's comments, with a copy
submitted to the SCIC for their files.
b) If the pedestrian survey is positive, the qualified archaeologist shall conduct
an updated archival search, if needed, as well as additional detailed field
testing. Local Native American groups shall be contacted for testing of
prehistoric cultural resources regarding the project. Where applicable, the

Cult-2
Findings of Fact
City will execute a Pre-Excavation Agreement with the appropriate Native
American groups.
1) Prior to the start of field testing, surface artifacts and/or features shall
be marked and mapped using a GPS. Testing shall be required if
surface artifacts are discovered, and shall include a program of
30-centimeter-diameter shovel test pits (STPs) to define site
boundaries and identify the potential for a substantial subsurface
deposit.
2) Based on the results of the STPs, additional measures such as Test
Excavation Units or mechanical trenching (for substantial historic
sites) would be placed in areas with the potential for a substantial
subsurface deposit, as determined by the qualified archeologist.
3) All excavated soils shall be screened through 118-inch mesh hardware
cloth. On completion of the project, the artifact collection, along with
copies of the catalogs and the technical report, shall be permanently
curated at the San Diego Archaeological Center. An updated site
record shall be prepared and submitted to the SCIC.
4) Within 3 months of completion of the fieldwork, a draft technical
report including evaluations and recommendations shall be prepared
and submitted. The final technical report shall be submitted within
6 weeks of receipt ofthe City's comments.
Monitoring Requirements -Construction monitoring will be required for
proposed PLDA or non-PLDA DMP Update components that involve excavation
or grading within undisturbed native soils and could potentially impact subsurface
cultural deposits, as indicated in Tables 4.11-2 and 4.11-3.
a) Prior to the first preconstruction meeting for the project, the Planning
Director (PD) shall verify that the requirements for archaeological
monitoring and Native American monitoring, if applicable, have been noted
on the appropriate construction documents. The applicant shall retain a
qualified archaeologist to verify that a records search has been completed
and updated, as necessary, and to implement the monitoring program. At
the preconstruction meeting, the archaeologist shall submit to the PD a copy
of the site/grading plan that identifies areas to be monitored.
b) The qualified archaeologist shall be present full-time during grading/
excavation of native soils with the potential to contain buried cultural
features or deposits and shall document activity via the Consultant Monitor
Record. Monitoring of trenches shall include mainline, laterals, services,
and all other appurtenances that impact native soils 1 foot deeper than
existing as detailed on the plans or in the contract documents. It is the
CEQA Findings of Fact 43 January 16, 2008

Findings of Fact
construction manager's responsibility to keep the archaeological monitors
up-to-date with current plans.
c) In the event of a discovery, the archaeologist, or the Principal Investigator
(PI) if the monitor is not qualified as a PI, shall divert, direct, or temporarily
halt ground-disturbing activities in the area of the discovery to allow for
preliminary evaluation of potentially significant archaeological resources.
The PI shall also immediately notify the construction manager and the PD of
such findings at the time of discovery.
I) The significance of the discovered resources shall be assessed by the
PI. For significant archaeological resources, a Research Design and
Data Recovery Program shall be prepared and implemented by the
qualified archaeologist. The results of the Research Design and Data
Recovery Program shall be approved by the City before ground-
disturbing activities in the area of discovery shall be allowed to
resume.
d) If human remains are discovered, work shall halt in that area and procedures
set forth in the California Public Resources Code (Sec. 5097 .98) and State
Health and Safety Code (Sec. 7050.5} shall be implemented. Construction
in that area shall not resume until the remains have been evaluated and
conveyed to appropriate descendants or reinterred to the satisfaction of the
PI.
e) The archaeologist shall notify the PD, in writing, of the end date of
monitoring. The archaeologist shall be responsible for ensuring that all
cultural remains collected are cleaned, catalogued, and permanently curated
with an appropriate institution; that a letter of acceptance from the curation
institution has been submitted to the Planning Department; that all artifacts
are analyzed to identify function and chronology as they relate to the history
of the area; that faunal material is identified as to species; and that specialty
studies are completed, as appropriate.
f) Within 3 months following the completion of monitoring, the Draft Results
Report (even if negative) and/or evaluation report, if applicable, which
describes the results, analysis, and conclusions of the Archaeological
Monitoring Program (with appropriate graphics) shall be submitted to the
PD for approval. For significant archaeological resources encountered
during monitoring, the Research Design and Data Recovery Program shall
be included as part of the Draft Results Report. The qualified archaeologist
shall be responsible for recording (on the appropriate State of California
Department of Park and Recreation forms-DPR 523 AlB) any significant or
potentially significant resources encountered during the Archaeological
Monitoring Program, and submitting such forms to the SCIC with the Final
Results Report.
CEQA Findings of Fact 44 January 16, 2008
EIR 04-02 Carlsbad Drainage Master Plan Update
Findings of Fact
3.3.4 Facts in Support
Implementation of Mitigation Measure Cult-1 will reduce potentially significant program level
impacts resulting from roads or surface disturbance through areas not adequately surveyed
because any unsurveyed area will undergo preconstruction surveys to verify adequate steps are
taken to protect and preserve any identified cultural resources. Through implementation of
Mitigation Measure Cult-1 potentially significant program level impacts to cultural resources
will be reduced to less than significant.
Implementation of Mitigation Measure Cult-2 will reduce potentially significant program level
impacts to undiscovered resources because an on-site construction monitor will be present during
excavation and grading of areas with potential resources to verify that ground-disturbing
activities are halted should resources be located. Through implementation of Mitigation
Measure Cult-2 potentially significant program level impacts to cultural resources will be
reduced to less than significant.
3.4 PALEONTOLOGICAL RESOURCES
3.4.1 Potentially Significant Impacts
The DMP Update and operation and maintenance activities have the potential to result in the
following potentially significant program level impact to paleontological resources:
• Grading and earthwork could disturb potentially unknown fossil remains and the
information in the fossils could be lost. (Paleo-1)
3.4.2 Finding
Mitigation measures have been identified in Final EIR that mitigate or avoid potentially
significant program level impacts to paleontological resources resulting from implementation of
the DMP Update.
3.4.3 Mitigation Measures
The Final EIR found that the above significant effect relating to program level and operation and
maintenance activities would be mitigated to a level considered less than significant through
implementation of the following mitigation measure:
Paleo-1 A monitoring program shall be prepared and implemented if excavation into
intact geologic formations with moderate to high sensitivity is proposed.
Components of such a monitoring program shall include, but not be limited to, the
following:
a) A qualified paleontological monitor shall be present at a pregrading meeting
with the construction contractor and PD (Planning Director) of the City
Planning Department. The purpose of the meeting will be to consult and
coordinate the role of the paleontologist during construction. The
CEQA Findings of Fact 45 January 16, 2008
EIR 04-02 Carlsbad Drainage Master Plan Update
. Findings of Fact
paleontological monitor shall have adequate knowledge and experience with
fossilized remains likely to be present to identify them in the field. The
paleontological monitor shall be adequately experienced to remove
paleontological resources for further study.
b) The paleontological monitor shall be present during the applicable stages of
grading and construction (including trenching), as determined at the
pregrading meeting. The paleontological monitor shall have the authority to
temporarily direct, divert, or halt grading in the area of an exposed fossil to
facilitate evaluation and, if necessary, salvage. At the discretion of the
monitor, recovery may include washing and picking of soil samples for
microvertebrate bone and teeth. Construction activities in the area of
discovery shall resume upon notification by the paleontologist that fossil
remains have been recovered. The City shall ensure the contractor is aware
of the random nature of fossil occurrences and the possibility of a discovery
of such scientific and/or educational importance that it might warrant a
long-term salvage operation or preservation. All fossils collected shall be
donated to a museum with a systematic paleontological collection, such as
the San Diego Natural History Museum. The City shall ensure the grading
contractor is aware of this provision. Conflicts regarding the role and
authority of the monitor shall be resolved by the PD or his/her designee.
c) Collected fossils shall be cleaned and/or prepared to a point of
identification, and then curated to museum standards (cataloging of locality
and specimen data, numbering, identification, labeling) before being
deposited in an appropriate public facility (or facilities) that can provide
permanent archival storage (so that specimens are available for future
scientific study). A report detailing the mitigation and any discoveries shall
be prepared and submitted to the City within 3 months following
termination of the paleontological monitoring program, even if negative.
The report shall include necessary maps, graphics, and fossil lists to
adequately document the paleontological monitoring program.
3.4.4 Facts in Support
Implementation of Mitigation Measure Paleo-1 will reduce potentially significant impacts
resulting from the potential disturbance and loss of fossil remains because the preconstruction
monitoring program will verify that steps will be taken to protect and preserve fossils if
unearthed during excavation and/or grading. Through implementation of Mitigation Measure
Paleo-1 potentially significant impacts to paleontological resources will be reduced to less than
significant.
3.5 CUMULATIVE IMPACTS (BIOLOGICAL RESOURCES)
3.5.1 Potentially Significant Impacts
CEQA Findings of Fact 46 January 16, 2008
EIR 04-02 Carlsbad Drainage Master Plan Update
Findings of Fact
The DMP Update would result in potentially significant long-term impacts to biological
resources. These impacts would be cumulatively significant when considered together with
other development projects in the City and the region due to the loss of sensitive habitat.
3.5.2 Finding
Mitigation measures have been identified in Final EIR that mitigate or avoid potentially
significant cumulative impacts to biological resources resulting from implementation of the
DMP Update.
3.5.3 Mitigation Measures
The Final EIR found that cumulative significant biological impacts would be mitigated to a level
considered less than significant through implementation of mitigation measures discussed above
in Sections 3.2.3 and 3.2.7, and detailed in Section 4.10 ofthe Final EIR.
3.5.4 Facts in Support
Implementation of Mitigation Measures Bio-I through Bio-7 would reduce significant
cumulative biological impacts to less than significant because of the rationale discussed above in
Sections 3.2.4 and 3.2.8.
4.0 FINDINGS REGARDING SIGNIFICANT UNAVOIDABLE IMPACTS
The City, acting as the Lead Agency under CEQA, finds that the Final EIR identifies no
significant unavoidable impacts.
CEQA Sections 21081 and 21081.5 and CEQA Guidelines Section 15091 provide that the City
shall not approve or carry out a project for which an EIR has been certified that identifies one or
more significant environmental effects of the project unless the City makes one or more of the
following Findings for each significant effect, based on substantial evidence in the record:
(1) Changes or alterations have been required in, or incorporated into, the Project
which avoid or substantially lessen the significant environmental effect;
(2) Such changes or alterations are within the responsibility and jurisdiction of
another public agency and not the agency making the finding, and such changes
have been, or can and should be, adopted by such other agency; and/or
(3) Specific economic, legal, social, technological, or other considerations make
infeasible the mitigation measures or project alternatives identified in the Final
EIR.
The City has determined that mitigation measures identified in the Final EIR will substantially
lessen the significant impacts identified above in Section 3 of these Findings. Such mitigation
measures have been incorporated into the MMRP, which will be included as a condition of the
City's approval ofthe DMP Update.
CEQA Findings of Fact 47 January 16, 2008
EIR 04-02 Carlsbad Drainage Master Plan Update
Findings of Fact
5.0 FINDINGS REGARDING INFEASIBLE ALTERNATIVES
In preparing and adopting findings, a lead agency need not necessarily address the feasibility of
both mitigation measures and alternatives when contemplating approval of a project with
significant impacts. Where a significant impact can be mitigated to an acceptable level solely by
the adoption of mitigation measures, the agency, in drafting its findings, has no obligation to
consider the feasibility of environmentally superior alternatives, even if their impacts would be
less severe than those of the project as mitigated. [Laurel Hills Homeowners Association v. City
Council (1978) 83 Cal. App. 3d 515, 521; Kings County Farm Bureau v. City of Hanford (1990)
221 Cal. App. 3d 692, 730-731; Laurel Heights Improvement Association v. Regents of the
University of California (1988) 47 Cal. 3d 376, 400-403.] Therefore, because the DMP Update
would not result in any significant unmitigable impacts, no findings are required regarding
infeasible alternatives.
6.0 FINDINGS REGARDING SIGNIFICANT IRREVERSIBLE ENVIRONMENTAL
CHANGES
The DMP Update would cause irreversible environmental changes consisting of the following:
Alteration of the human environment as a consequence of the development process. In
particular, the DMP Update would result in the alteration of natural drainages, sensitive
biological habitats, and wetlands to provide drainage improvements, flood protection, and
indirect improvements to storm water quality control. Impacts to these sensitive resources would
be reduced to a less than significant level with the mitigation measures included in the Final EIR.
Use of nonrenewable natural resources for construction, operation, and maintenance of project
components. The proposed DMP Update would not use nonrenewable fossil fuels, such as
diesel, gasoline, or oil for construction equipment at a greater rate than other typical construction
projects; increase the overall rate of use of any nonrenewable natural resource; or result in the
substantial depletion of any nonrenewable resource.
7.0 FINDINGS REGARDING THE MITIGATION MONITORING AND
REPORTING PROGRAM
The City Council hereby adopts the MMRP attached to this Resolution as Exhibit B. In the
event of any inconsistencies between the mitigation measures set forth herein and the MMRP,
the MMRP shall control. The MMRP will be adopted as part of the conditions of approval for
the DMP Update, pursuant to CEQA Section 21081.6 and CEQA Guidelines Section 15097.

Implementation of mitigation measures Bio 1-a through Bio 1-d would be required for DMP Update components that would impact sensitive Habitat Management Plan (HMP)
habitats and would reduce direct and cumulative impacts to below a level of significance. Note that the descriptions of Type A through F habitats are per Table 11 of the HMP.
Avoidance and on-site mitigation are the priority. Future project level environmental review for DMP Update components that would impact biological resources would be
provided to the Wildlife Agencies for review to verify consistency with the Cit 's HMP.

determined by the applicable resource agencies at the time of
PJOlect permitting.
Bio-1b Impacts to Type B habitats (beach, southern coastal bluff Pre-City of Carlsbad,

The following mitigation measures shall be implemented during construction of PLDA and non-PLDA project components proposed in geologic formations with a moderate
to high sensitivity for paleontological resources, including Unnamed Marine Terrace Deposits, Unnamed River Terrace Deposits, Santiago Formation, Del Mar Formation,
Point Lorna Formation, Lusardi Formation, or Undifferentiated Santiago Peak Volcanics. Determination of the underlying geologic formations shall be determined during

impacts to paleontological resources to below a level of significance.
Paleo-1 A monitoring program shall be prepared and implemented if
excavation into intact geologic formations with moderate to
high sensitivity is proposed. Components of such a monitoring
program shall include, but not be limited to, the following:
a) A qualified paleontological monitor shall be present at a
pregrading meeting with the construction contractor and
Planning Director (PO). The purpose of the meeting will
be to consult and coordinate the role of the paleontologist
during construction. The paleontological monitor shall
have adequate knowledge and experience with fossilized
remains likely to be present to identify them in the field.
The paleontological monitor shall be adequately
experienced to remove paleontological resources for
further study.
b) The paleontological monitor shall be present during the
applicable stages of grading and construction (including
trenching), as determined at the pregrading meeting. The
paleontological monitor shall have the authority to
temporarily direct, divert, or halt grading in the area of an
exposed fossil to facilitate evaluation and, if necessary,
salvage. At the discretion of the monitor, recovery may
include washing and picking of soil samples for
microvertebrate bone and teeth. Construction activities in
the area of discovery shall resume upon notification by the
paleontologist that fossil remains have been recovered.
The City shall ensure the contractor is aware of the
random nature of fossil occurrences and the possibility of
a discovery of such scientific and/or educational
importance that it might warrant a long-term salvage

3.4 PROJECT LEVEL PROJECT DESCRIPTION
In addition to the program level analysis of project components that are currently at a
preliminary stage of design, some components identified with the DMP Update are at a
point in the design process that enables a project level analysis. The City has identified
and initiated design oftwo DMP Update components, B and BN, also collectively known
as the Agua Hedionda and Calavera Creeks Dredging and Improvements Project. These
components are evaluated at a project level in this document.
The City proposes to conduct drainage infrastructure modifications and improvements
along Agua Hedionda and Calavera creeks to provide enhanced flood protection for the
residential community of Rancho Carlsbad, an existing residential mobile home
community located east of El Camino Real and south of Cannon Road, in the
northeastern section of Carlsbad. Over 50 percent of the homes in Rancho Carlsbad are
located within the existing limits ofthe 100-year floodplain and could be subject to flood
damage during a major storm event. Within the DMP Update, the Agua Hedionda Creek
project components are included as Project B, and the Calavera Creek project
components are included as Project BN. Projects Band BN are farther along in the design
process, and therefore a sufficient level of detail is available to evaluate these projects at
a project level within this EIR.
Projects B and BN have both PLDA and non-PLDA elements, as shown in Tables 3-3
and 3-4, respectively, and described in more detail below. Together, Projects B and BN
would reduce flooding in the Rancho Carlsbad residential community by improving the
capacity of Agua Hedionda and Calavera creeks, within Rancho Carlsbad, to contain a
1 00-year flood event (all but approximately a maxiffil:lm of nine lots would be alleviated
from inundation during a 1 00-year flood event).
3.4.2 Project Background
The improvements to Agua Hedionda and Calavera creeks are an integral part of the
DMP Update and are essential components of the flood control and protection measures
outlined for the city. Based on visual inspections and preliminary engineering, the overall
channel conveyance capacity of Agua Hedionda Creek has been reduced through the
deposition of 4 to 6 feet of sediment accumulated over the 36 years since the original
construction of the channel, creating a backwater effect within the Calavera Creek
conveyance. This reduces the conveyance capacity of Calavera Creek. Localized scour
along Calavera Creek banks has threatened to undermine residential foundations during
heavy storm events. Several homeowners have installed revetment walls (constructed of
treated lumber and steel "I-beams") and/or rock slope protection to protect their homes
from damage during heavy storm events. Approximately maKimum of nine units would
Exhibit "EIR-C" to Planning Commission Resolution 6376
January 16, 2008
partially remain subject to inundation during a 1 00-year flood event following
implementation of the proposed DMP Update. The All aiae units that would partially
remain in the 1 00-year floodplain under the proposed scenario are on elevated
foundations that would raise their first-floor elevation above the 1 00-year floodplain
level. Long-term maintenance of both creeks is also proposed to maintain flood
protection levels in Rancho Carlsbad.
7.1.2 Project Level
Following the 1996 amendment to the MDSQMP to include Agua Hedionda Creek as a
PLDA project (see Section 3.1.1), the City contracted Rick Engineering Company to
conduct a study to evaluate various design alternatives to achieve 1 00-year flood capacity
in Agua Hedionda and Calavera creeks (Rick Engineering Company 2004). The design
alternatives considered various combinations of the following actions: improvements to
Calavera Dam and the existing BJB Basin, construction of new detention basins (referred
to as Melrose, Faraday, and BJ in the Rick Engineering Company report), and channel
improvements and dredging within Agua Hedionda Creek. Dredging and maintenance
within Calavera Creek were not considered as part of these alternatives. These
alternatives were ultimately rejected, however, because they did not provide 1 00-year
flood protection for as many lots as feasible (compared to the proposed DMP Update
components, which would alleviate all but approximately nine lots from inundation
during a 100-year flood event}.
Appendix F-Response to Comments
L3-49 The City does not intend to acquire any lots with private residents for habitat
preservation purposes. The primary objective of the dredging and improvements
to Agua Hedionda and Cal avera creeks is to provide 1 00-year flood protection to
the maximum number of lots as feasible and practicable. In this case, all but
approximately 9 lots would receive protection from a 1 00-year flood event.

CASE NAME: AGUA HEDIONDA AND CALA VERA
CREEKS
CASE NO.: CDP 06-04
WHEREAS, City of Carlsbad, "Developer," has filed a verified application with
the City of Carlsbad regarding property owned by Carlsbad Canterbury Association and
Evans Point Homeowners Association, "Owners," with easements granted or dedicated to
the City of Carlsbad for road, drainage, open space, sewer, and maintenance purposes and
described as
A portion of Lot 148 of City of Carlsbad Tract No 96-07, Kelly

relating to the CDP.
NOW, THEREFORE, BE IT HEREBY RESOLVED by the Planning
Commission of the City of Carlsbad as follows:
A)
B)
That the foregoing recitations are true and correct.
That based on the evidence presented at the public hearing, the Commission
APPROVES AGUA HEDIONDA AND CALA VERA CREEKS -CDP 06-04
based on the following findings and subject to the following conditions:
Findings:
1.
2.
3.
That the proposed development is in conformance with the Certified Local Coastal
Program (LCP) and all applicable policies in that it is the intent of the LCP to allow
implementation of drainage projects that are part of the City's drainage master
planning program.
The proposal is in conformity with the public access and recreation policies of Chapter 3
of the Coastal Act in that the project involves dredging of existing creeks that are not
navigable, used for recreation or bordered by public trails or recreation areas.
The project is consistent with the provisions of the Coastal Resource Protection Overlay
Zone (Chapter 21.203 of the Zoning Ordinance) in that the project will adhere to the
City's Master Drainage Plan (as well as the proposed Drainage Master Plan Update),
Grading Ordinance, Storm Water Ordinance, Standard Urban Storm Water Mitigation
Plan (SUSMP), and Jurisdictional Urban Runoff Management Program (JURMP) to
avoid increased urban runoff, pollutants, and soil erosion. No steep slopes are located on
the subject property and the site is not located in an area prone to landslides. To enhance
flood control, the project does propose removal of native vegetation and
construction of improvements within a floodway; however, the existing Local
Coastal Program requires storm drainage facilities in developed areas to be
improved and enlarged according to the City's existing Master Drainage Plan and
thus it is the intent of the LCP to allow implementation of drainage projects that are
part of the City's drainage master planning program. Furthermore, LCP Policy 3-
1. 7(a)(5) permits impacts to wetlands for dredging required for public service
purposes and there is no feasible alternative to dredging the area between the El
Camino Real and Cannon Road bridges (the portion of the project within the
Coastal Zone) that would provide flood protection to Rancho Carlsbad to the extent
feasible and restore 100-year flood capacity in the creeks. Finally, impacts to
wetlands would be mitigated to a level of insignificance, and the portion of the
project within the Coastal Zone is not part of a Habitat Management Plan Hard line
Preserve.

Natural vegetation would be retained as much as possible, such as along creek
banks. Additionally, on-site mitigation could potentially occur on the creek banks,
where feasible, to restore natural vegetation in place of existing exotic or ornamental
vegetation. Further, the long-term maintenance plan would promote the growth of
native vegetation on the creek bank where appropriate and discourage
establishment of invasive exotic, nonnative, and ornamental vegetation via
maintenance activities.
Implementation of the project's Stormwater Pollution Prevention Program and
long-term maintenance plan would be consistent with requirements of LCP policies
4-5 (erosion control) and 4-6 (sediment control).
This Coastal Development Permit has been submitted following the City's issuance
of an emergency Coastal Development Permit on February 6, 2006, to permit
emergency dredging of the project portion of Agua Hedionda Creek within the
Coastal Zone. Mitigation for biological impacts associated with the emergency work
have been or will be mitigated separately from this Coastal Development Permit.
Subject to the conditions of approval, this Coastal Development Permit also permits
improvements and dredging beyond those accomplished by the emergency permit
and includes a long term maintenance plan for creek dredging and enhanced flood
control on a permanent basis.
Conditions:
Note: Unless otherwise specified herein, all conditions shall be satisfied prior to issuance of a
grading permit or start of construction, whichever occurs first.

If any of the following conditions fail to occur, or if they are, by their terms, to be
implemented and maintained over time, if any of such conditions fail to be so
implemented and maintained according to their terms, the City shall have the right to
revoke or modify all approvals herein granted; deny or further condition issuance of all
future building permits; deny, revoke, or further condition all certificates of occupancy
issued under the authority of approvals herein granted; record a notice of violation on the

3.
The site is reasonably safe from flooding in that while the project proposes
construction in a floodplain, construction is temporary and designed to enhance
flood protection of existing creeks, thereby increasing the safety from flooding of the
Rancho Carlsbad residential community.
The project as proposed has been designed to minimize the flood hazard to the habitable
portions of the structure in that while no habitable structures are proposed, the project
would result in removing all but nine of the current 278 Rancho Carlsbad homes
from being subject to inundation during a 100-year storm event.
The proposed project does not create a hazard for adjacent or upstream properties or
structures in that the proposed project would remove nearly 270 homes in the Rancho
Carlsbad residential community from the threat of flooding during a 100-year storm
event.

The proposed project does not create any additional hazard or cause adverse impacts to
downstream properties or structures in that immediately below the project, Agua
Hedionda Creek opens to a wide undeveloped floodplain that extends to Agua
Hedionda Lagoon.
The proposed project does not reduce the ability of the site to pass or handle a base flood
of 1 00-year frequency in that the project would increase the ability of Agua Hedionda
and Calavera creeks to pass floodwaters of such frequency.
The proposed project taken together with all the other known, proposed, and anticipated
projects will not increase the water surface elevation of the base flood more than one foot
at any point in that the proposed project will dredge and improve Agua Hedionda
and Calavera creeks, thereby lowering and widening the creeks and increasing their
floodwater capacity.
All other required state and federal permits have been or will be obtained prior to
issuance of permits for grading, dredging or construction of the project.

WHEREAS, the City of Carlsbad has received authorization to issue permits to
impact various sensitive species and habitats, including species listed as Threatened or
Endangered, by virtue of Incidental Take Permit No. TE022606-0 from the U.S. Fish and
Wildlife Service and Natural Community Conservation Planning Permit No. 2835-2004-00I-05;
and
WHEREAS, the authority stated above is based on a plan titled Habitat
Management Plan for Natural Communities in the City of Carlsbad, Final Approval November
2004, referred to as the HMP, and approval of all projects is contingent on a finding of
consistency with the HMP; and
WHEREAS, said verified application by Developer constitutes a request for a
Habitat Management Plan Permit pursuant to the City's authority as contained in Chapter
21.2I 0 of the Zoning Ordinance, on file in the Planning Department; and
WHEREAS, the Planning Commission did on January 16, 2008, hold a duly
noticed public hearing as prescribed by law to consider said request; and
WHEREAS, at said hearing, upon hearing and considering all testimony and
arguments, if any, of all persons desiring to be heard, said Commission considered all factors
relating to the Habitat Management Plan Permit.
NOW, THEREFORE, BE IT HEREBY RESOLVED by the Planning
Commission as follows:
A) That the foregoing recitations are true and correct.
B)
C)
That the AGUA HEDIONDA AND CALA VERA CREEKS project 1s
consistent with the HMP as described in the following findings.
That based on the evidence presented at the hearing, the Commission
APPROVES the Habitat Management Plan Permit, HMPP 06-03, for the AGUA
HEDIONDA AND CALA VERA CREEKS project based on the following
findings and subject to the following conditions:

Findings:

That the Agua Hedionda and Calavera Creeks project is shown in Figure 28 of the
approved HMP as "development area" east of El Camino Real and "development
area" and "existing Hardline Preserve area" west of El Camino Real. However, the
portion of the creek shown as within the existing Hardline Preserve area is actually
not in a Hardline Preserve based on a detailed examination of recorded documents
affecting the area.
That authorization to take species of concern, through the take of 0.08 acre of Willow
Riparian Forest, is subject to continuous compliance with all provisions of the Habitat
Management Plan for Natural Communities in the City of Carlsbad (HMP), the Citywide
Incidental Take Permit issued for the HMP, the Implementing Agreement, the Terms and
Conditions of the Incidental Take Permit, and the Biological Opinion. Biological impacts
associated with the 2006 emergency dredging of Agua Hedionda and Calavera
creeks are mitigated separately from those impacts associated with the project.
That authorization to take species of concern is subject to continuous compliance with all
mitigation measures as stated in the Mitigation Monitoring and Reporting Program
for EIR 04~02 as contained in Planning Commission Resolution 6376 and is subject to
all conditions contained in Planning Commission Resolutions No. 6376, 6379 and 6380
for those other approvals, including but not limited to recordation of conservation
easements over all conserved areas and management and monitoring in perpetuity by a
qualified conservation entity.
That authorization to take species of concern is subject to continuous compliance with the
provisions of Volumes I, II and III of the Multiple Habitat Conservation Program and the
Final Environmental Impact Statement/Environmental Impact Report for Threatened and
Endangered Species Due to Urban Growth within the Multiple Habitat Conservation
Program Planning Area (SCH No. 93121073).
That all impacts to habitat and all take of species will be incidental to otherwise lawful
activities related to construction, operation, and maintenance of the Agua
Hedionda/Calavera Creeks project in that the dredging and improvements to
enhance the flood control capabilities of existing drainage facilities are acceptable
activities and are subject to approval of all required permits before work occurs.
The development project complies with the purpose and the intent provisions of Carlsbad
Municipal Code Section 21.210.10 in that the Agua Hedionda and Calavera Creeks
project is consistent with (a) the General Plan Land Use and Public Safety Elements
because the General Plan authorizes existing drainage infrastructure and planned
capacity improvements to support all designated land uses in the city and establishes
policies to provide flood protection to developed areas; (b) the Open Space and
Conservation Element in that impacts to sensitive habitat are mitigated to a level of
insignificance and are avoided if possible; (c) the Habitat Management Plan in that
the project proposes appropriate design features and mitigation measures as
identified in the Final EIR 04~02 to reduce biological impacts to a level of
insignificance.

That the project design as approved by the City of Carlsbad has avoided and minimized
impacts to wildlife habitat and species of concern to the maximum extent practicable.
Specifically, (a) there is no feasible alternative to dredging the creeks or impacting
wetlands that would provide flood protection to Rancho Carlsbad to the extent
feasible and restore 100-year flood capacity in the creeks; (b) all biological impacts
can be reduced to a level of insignificance through mitigation measures that require
among other things, best management practices to limit indirect temporary impacts
due to construction (e.g., dust, noise, water quality) and creation/restoration/and
enhancement of wetland and riparian habitat; (c) natural vegetation would be
retained as much as possible, such as along creek banks; (d) on-site mitigation could
potentially occur on the creek banks, where feasible, to restore natural vegetation in
place of existing exotic or ornamental vegetation; (e) the long-term maintenance
plan would promote the growth of native vegetation on the creek bank where
appropriate and discourage establishment of invasive exotic, nonnative, and
ornamental vegetation via maintenance activities; (f) the majority of the project is in
area the Habitat Management Plan indicates is "developed area" and none of the
project is in a Hardline Preserve Area, and: (g) the project is consistent with Local
Coastal Program polices, including those regarding wetland impacts, vegetation
preservation, and sediment and erosion control.
That adequate funding has been provided to address changed circumstances and adaptive
management needs that may be reasonably anticipated in the future, consistent with the
HMP Implementing Agreement.
That the incidental take of species of concern as a result of the project will not
appreciably reduce the likelihood of survival and recovery of the species in the wild due
to compliance with all of the above stated requirements, as well as ongoing monitoring
and reporting to the wildlife agencies and the public.
That the Planning Director is authorized to sign the Take Permit.
Conditions:
Note: Unless otherwise specified herein, all conditions shall be satisfied prior to issuance of a
2I grading permit or start of construction, whichever occurs first.

future building permits; deny, revoke, or further condition all certificates of occupancy
issued under the authority of approvals herein granted; record a notice of violation on the

RE: EIR -4-02(A)/CDP 06-04 xl(A)/SUP 06-02 xl(A)-Agua Hedionda &
Calavera Creeks
Dear Commission:
The Agua Hedionda Lagoon Foundation has reviewed the staff report for the
proposed Aqua Hedionda & Calavera Creeks dredging and bank stabilization
project a members of oqr Board has discussed the proposed project with Sherri
Howard and Pam Drew. We would like to go on record as supporting the
proposed project which is a revision to the previously approved project which
our Foundation also supported. We believe that the proposed project will reduce
a serious flood hazard within the Rancho Carlsbad Mobile Home Park while
improving the overall quality of the water that will be flowing into Agua
Hedionda Lagoon from the Agua Hedionda & Calavera Creeks.
Sincerely,
Mike Metts
