Fiscal Vear 2017-18 Growth Management Plan Monitoring Report
This memorandum provides a summary of the major findings identified in the Fiscal Year 2017-
18 Growth Management Plan Monitoring Report.
Background
Carlsbad Municipal Code Section 21.90.130(d) requires the preparation of an annual monitoring
report on the Growth Management Plan (GMP). The report includes an analysis of development
activity, an adequacy analysis of public facilities and improvements, public facility financing, and
the status of the Proposition E dwelling unit caps.
Discussion
Attached to this memorandum is the GMP Monitoring Report for fiscal year (FY) 2017-18. The
major findings of the report are as follows:
1. Building permits for 341 dwellings and 1,643,467 square feet of non-residential space were
issued during FY 2017-18.
2. The total number of dwelling units in each quadrant continues to comply with the Growth
Management Plan limitations.
3. This report identifies a performance standard deficiency for the Circulation facility, due to
certain road segments not meeting the required vehicle level of service standard. For more
information, please see pages 19-26 of the report.
4. All other public facilities are currently meeting their adopted growth management
performance standards for FY 2017-18. The report continues to identify which public facilities
will need to provide additional improvements to meet their performance standards at
buildout.

Carlsbad's Growth Management Plan continues to meet its objective of assuring adequate public
facilities concurrent with the need created by new development.
Next Steps
When a performance standard deficiency has been identified as noted in item 3 above, Carlsbad
Municipal Code Section 21.90.130(c) requires the city council to determine that a deficiency
exists and to approve a proposal for how to address the deficiency. At the July 9, 2019, City
Council Meeting, staff will present an informational item on the GMP, circulation performance
standard, the 2015 GP Mobility Element adoption, and traffic impact analysis methodologies. At
the July 16, 2019, City Council Meeting, staff will present an item to address deficiencies which
will include a list of street segments that are deficient and proposals to address each deficiency,
including funding certain capital improvement roadway/circulation projects, approving
exemptions as allowed under General Plan Policy 3-P.9, and/or incorporating Transportation
Demand Management (TDM) and Transportation· System Management (TSM) mitigation
measures.

Introduction
The purpose of this report is to provide information regarding the status of the Carlsbad Growth
Management Plan for the fiscal year covering July 1, 2017 -June 30, 2018, and to verify that the plan
is continuing to accomplish its stated objectives. The primary objectives of the Growth Management
Plan are to ensure that adequate public facilities are provided concurrent with growth, and to assure
compliance with the ultimate dwelling unit limitations that were established by Proposition E, which
was passed by voters in 1986.
Performance Standards
Proposition E established broad guidelines for determining adequacy of public facilities. These
guidelines are further defined in the Citywide Facilities and lmprnvements Plan by means of specific
performance standards for each of the eleven public facilities. These public facilities, their
performance standards, current status, and anticipated adequacy at buildout are outlined in Table 1
and Table 2, as follows:

What Happens if Facilities Do Not Meet the Performance Standard?
The Growth Management Plan requires development activity to stop if a performance standard is
not being met. Some performance standards apply to the city as a whole, and others apply to more
specific areas, as described below:
• Administrative facilities, library, and wastewater treatment capacity are facilities that serve the
entire city. Their adequacy in meeting the performance standard is analyzed by considering the
cumulative impact of citywide development. The failure of any one of these facilities to meet
the adopted performance standard would affect the city as a whole. In that event, all
development in the city would be halted until the deficiency is corrected.
• Parks are analyzed on a quadrant basis. This means that if the standard is not being met in the
quadrant, development is halted for all Local Facility Management Zones (LFMZs, see
description below) in the quadrant.
• Fire facilities are analyzed on the basis of fire station districts which can comprise multiple
LFMZs, and if the standard is not met for a district, then development would be halted in that
district.
• The remaining facilities (drainage, circulation, open space, schools, sewer collection system, and
water distribution system) are analyzed on an LFMZ basis. If one of these facilities falls below
the performance standard in a given LFMZ, development in that LFMZ would stop and other
zones would not be affected if they are continuing to meet all performance standards.
Local Facility Management Zone Plans
The Citywide Facilities and Improvements Plan divided the city into twenty-five Local Facilities ·
Management Zones (LFMZ). Each LFMZ is required to have an adopted Local Facilities Management
Plan (LFMP) prior to any development in the LFMZ. Consistent with the Growth Management Plan,
the LFMP must do the following: describe how the LFMZ will be developed, how compliance with the
Growth Management Plan standards will be achieved, how the necessary public facilities will be
provided, and what financing mechanisms will be used for the facilities. All twenty-five LFMZs have
an adopted LFMP.
Please see Figure 1 for the general boundaries and locations of the LFMZs.

Population as a Measurement for Facility Performance Standards
As indicated in Table 1, above, the performance standards for city administrative facilities, library
facilities, and parks are stated in terms of population. The demand for these facilities is based on
each new dwelling unit built and the estimated number of new residents it adds to the city, which is
determined using the average number of persons per dwelling unit. Utilizing data from the 2010
Federal Census (total population divided by total number of dwelling units), the average for Carlsbad
is 2.358 persons per dwelling unit.
As of June 30, 2018, the city's population is estimated to be 110,306, which is calculated by
multiplying 2.358 persons per dwelling unit by the number of dwelling units, accessory dwelling units,
and commercial living units (which were counted as dwelling units in the 2010 Federal Census); in
total there are 46,734 dwellings and commercial living units, as shown in Table 3 below.

As part of the Growth Management Plan monitoring process, the persons per dwelling unit number
can be adjusted in the future when updated Federal Census data is available. It should be noted that
the above population estimates are for growth management facility planning purposes only and may
vary from other official population estimates for Carlsbad.
1 Dwelling units represent the dwellings that are counted for purposes of the city's growth management dwelling unit limits per
Proposition E (excludes accessory dwelling units and commercial living units); the number of dwelling units shown in this table are
updated to June 30, 2018.
2 Accessory dwelling units are accessory to single family dwellings and are separate dwelling units with living space, kitchen and
bathroom facilities. Pursuant to state law, accessory dwelling units cannot be counted as dwellings for purposes of the city's growth
management dwelling limits. However, the units are counted here to ensure all city population is considered in regard to the
performance standards for administrative facilities, libraries and parks.
3 Commercial living units, as shown in this table, are professional care facility living units that were counted as dwelling units in the
2010 Federal Census. Pursuant to city ordinance (CMC 21.04.093), commercial living units are not counted as dwellings for purposes
of the city's growth management dwelling limits. However, the units are counted here to ensure all city population is considered in
regard to the performance standards for administrative facilities, libraries and parks.

Residential Development Activity
Building permits for 341 new dwelling units were issued during the FY 2017-18. Table 4 provides a
breakdown by quadrant and LFMZ, excluding the zones that had no development activity. Figure 2

Proposition E Compliance
The purpose of this part of the report is to demonstrate that the ultimate dwelling unit caps stated
in Proposition E will not be exceeded. Proposition E states "the maximum number of residential
dwelling units to be constructed or approved in the city after November 4, 1986 is as follows:
Northwest Quadrant 5,844; Northeast Quadrant 6,166; Southwest Quadrant 10,667; Southeast
Quadrant 10,801." This resulted in dwelling unit caps as shown in Table 6 (see the totals for each
quadrant below). All quadrants are in compliance with the dwelling unit caps established by
Proposition E for FY 2017-18. As noted above in Table 3, accessory dwelling units and commercial
living units are not counted as dwellings for purposes of Growth Management Plan compliance with
the Proposition E caps.

Table 6 represents the number of dwelling units that could be built (based on the applicable growth
management density) on all parcels that have a residential land use designation. The "total existing
and unbuilt planned dwellings", as shown in Table 6, assumes all parcels with a residential land use
designation will be developed with residential dwellings, including land that is currently developed
with non-residential uses (e.g., some existing churches and professional care facilities are on land
designated for residential use). Although it is not anticipated that these parcels will convert to
residential uses, the dwelling unit potential for these parcels is tracked to ensure compliance with
the Proposition E dwelling unit limits.
4 All quadrants except the Village -includes unbuilt approved projects, as well as vacant and underdeveloped property
designated for residential use by the General Plan.
5 Dwelling unit capacity in addition to what is currently planned by the General Plan or approved as part of an unbuilt
project. "Potential additional .dwellings" must be allocated from Excess Dwelling Unit Bank.

Table 6 represents the total number of dwellings planned by the General Plan, rather than the
number of dwellings estimated to exist in the future. Table 7 estimates the number of dwellings that
will exist at buildout; this estimate assumes that the residentially designated land currently
developed with non-residential uses will not all be developed with residential uses in the future. The
data in Table 6 and Table 7 show that the Proposition E dwelling unit limits will not be exceeded.

Density Control Points and Excess Dwelling Unit Bank
To manage compliance with the Proposition E dwelling unit limitations, the City Council established
Growth Management Control Point (GMCP) densities for all residential land use designations in the
city (for example, for the R-4 land use designation, the GMCP density is 3.2 dwelling units per acre).
All residential development must, on average, not exceed the GMCP densities. To ensure this,
Council Policy Statement 43 (Proposition E "Excess Dwelling" Unit Bank) established a dwelling unit
bank concept. When development occurs below the GMCP, the "excess" number of units (difference
between the potential number of units at the GMCP density and the number of units built) are
available for other residential developments to allow them to be constructed at a density that
exceeds the GMCP density.
On December 17, 2002, the City Council adopted Resolution No. 2002-350, which amended Council
Policy Statement 43 by reducing the accumulated number of excess units to 2,800. Excess units may
be allocated to any quadrant based on the criteria in Council Policy Statement 43, so long as the
citywide or individual quadrant dwelling unit limits are not exceeded. Please see Table 8 for the
Excess Dwelling Unit Bank status at the end of the FY 2017-2018. "Pending" excess units are
associated with projects that have been approved below the GMCP density but are not yet
constructed, or an approved land use change is not yet effective. "Pending" excess units are not
available to allocate to other sites; the units will be made available for allocation at the time the
associated projects are constructed, or the land use change becomes effective.

Public Facility Financing
In 1991, the City of Carlsbad established Community Facilities District No. 1 (CFD) to provide financing
for a number of public facilities of citywide importance that are needed to meet the requirements of
the Growth Management Plan, including various road and intersection improvements, and the Dove
Library. As LFMZ plans were adopted, they were conditioned to annex into the CFD at the time the
first discretionary permit grants an entitlement to develop in the LFMZ. This ensures financing for
public facilities that can accommodate future growth consistent with the criteria of the Growth
Management Plan.
Status of the Facilities
Beginning on page 12 is a discussion of the adequacy of each of the eleven public facilities addressed
in Carlsbad's Growth Management Plan.
11
CITY ADMINISTRATIVE FACILITIES
A. Performance Standard
1,500 sq. ft. per 1,000 population must be scheduled for construction within a five-year
period or prior to construction of 6,250 dwelling units, beginning at the time the need is first
identified.
B. FY 2017-2018 Facility Adequacy Analysis
Based on the estimated June 30, 2018 population estimate of 110,306, the current demand
for administrative facilities is 165,459 square feet. To date, city administrative facilities
exceed the performance standard. The existing inventory of city and Carlsbad Municipal
Water District buildings (leased and owned) occupied for administrative services includes the
following:
Facility Address Square Feet
City Administration 1635 Faraday Avenue 68,000
City Council Chambers 1200 Carlsbad Village Drive 2,500
City Hall Complex 1200 Carlsbad Village Drive 13,500

Fleet Yard 2480 Impala Drive 10,358
Water District 5950 El Camino Real 18,000
Water District Modular 5950 El Camino Real 696
Total 214,469
C. Buildout Facility Adequacy Analysis
Based on the 2035 projected buildout population of 131,523, the demand for city
administrative facilities will be 197,285 square feet. The existing 214,469 square feet of
administrative facilities exceeds the growth management performance standard at buildout.
12
LIBRARY FACILITIES
A. Performance Standard
800 sq. ft. (of library space) per 1,000 population must be scheduled for construction within
a five-year period or prior to construction of 6,250 dwelling units, beginning at the time the
need is first identified.
Library space (leased/owned, public/non-public) is used as a standard library measurement
of customer use and satisfaction and includes collection space, seating, meeting rooms, staff
areas, technology, and other public facility needs. The performance standard, stated above,
was originally developed based on surveys of other libraries of comparable size and based on
related standards (such as volumes per capita) set by the American Library Association.
B. FY 2017-18 Inventory and Adequacy of Facilities
The current inventory of library facilities (city-owned) is as follows:
Facility Square Feet
Dove Library 64,000
Cole Library 24,600
Learning Center 11,393
Total 99,993
Based on the June 30, 2018 population estimate of 110,306, the growth management
standard requires 88,245 sq. ft. of public library space. The city's current 99,993 sq. ft . of
library facilities adequately meets the growth management standard.
C. Facility Adequacy at Buildout
Based on the General Plan projected buildout population of 131,523, the demand for library
facilities will be 105,218 sq. ft. The existing 99,993 square feet of library facilities is expected
to fall short of the growth management standard at buildout.
In 2015-16, the city completed major maintenance and renovation for both the Cole and Dove
facilities that addresses current ADA requirements and allows delivery of modern library
services and technology, while extending the life of the Cole Library by 10 to 15 years.
Built in 1967, the design of the Cole Library could not have contemplated modern library
services including the extensive delivery of electronic resources, automated materials
handling, and the variety of new media formats. Additionally, the library's role as a
community gathering space has increased. With an already maximized building footprint and
infrastructure constraints, the Cole Library will not expand further to meet these changing
13
needs. Additional meeting spaces, technology learning labs and maker spaces are examples
of elements desired by the community.
Complete replacement of the Cole facility is included in the Cap ital Improvement Program
budget between the years 2020 and buildout. Additionally, civic center and city hall site
studies, which are currently underway, will most likely inform the timing and opportunities
for a new Cole facility. One of the sites being considered for a new city hall and potential civic
center is the property that currently includes Cole. As these plans advance, staff will need to
evaluate impacts on a future library space.
14
WASTEWATER TREATMENT CAPACITY
A. Performance Standard
Sewer plant capacity is adequate for at least a five-year period.
B. FY 2017-18 Facility Adequacy Analysis
The Encina Water Pollution Control Facility (EWPCF) Phase V expansion, which was completed
in 2009, accommodates the ultimate buildout demand for the Carlsbad Sewer Service Area
based on projections made in the 2012 City of Carlsbad Sewer Master Plan; and therefore,
currently provides adequate capacity in excess of the performance standard.
Carlsbad's FY 2017-18 annual daily average dry weather sewer flow was 6.18 million gallons
per day (MGD) representing 60% of the city's 10.26 MGD capacity rights. The city's annual
daily average sewage flow to the EWPCF for the previous five years is measured as follows:
Fiscal Year Annual daily average flow
FY 2013-14 5.90 MGD
FY 2014-15 6.17 MGD
FY 2015-16 5.82 MGD
FY 2016-17 6.32 MGD
FY 2017-18 6.18 MGD
C. Buildout Facility Adequacy Analysis
The Encina Water Pollution Control Facility Phase V expansion provides adequate sewer
treatment capacity to ensure compliance with the growth management wastewater
performance standard through buildout of the Carlsbad sewer service area.
The 2012 City of Carlsbad Sewer Master Plan contains an analysis of annual daily average
future sewer flow through buildout of the city based on the Carlsbad General Plan land use
projections. The analysis indicates that the city's projected ultimate buildout flow is
approximately 10.00 MGD. The city has purchased capacity rights to 10.26 MGD in the
EWPCF, which ensures adequate wastewater treatment capacity is available to accommodate
any unanticipated increase in future sewer flows.
15
PARKS
A. Performance Standard
3.0 acres of Community Park or Special Use Area per 1,000 population within the Park District6
must be scheduled for construction within a five year period beginning at the time the need
is first identified7• The five year period shall not commence prior to August 22, 2017.
B. FY 2017-18 Facility Adequacy Analysis
To date, all quadrants are in compliance with the performance standard.
Quadrant Park acreage inventory existing Park acreage required by
Performance Standards
NW 105.2 90.7
NE 45.3 46.2
SW 70.2 76.9
SE 114.9 117.2
Total 335.6 330.9
The performance standard requirement for park acreage exceeds the inventory of existing
and scheduled park acreage for the NW quadrant, but the other quadrants do not currently
meet the performance standard. Although short of the acreage required, these quadrants
are not out of compliance with the performance standard because the five year period has
not been reached. For the SW and SE quadrants, the five year period began on August 22,
2017 as required by City Council Resolution No. 2017-170. For the NE quadrant, this FY 2017-·
18 report has identified a new park acreage deficit, so the five year period began on June 30,
2018.
The completion of the Veterans Memorial Park Master Plan will address the referenced
deficits in the NE, SW and SE quadrants. Veteran's Memorial Park is a city-owned,
undeveloped community park site located in the northwest quadrant. Because of its size,
centralized location, and citywide significance, the city intends that this site help fulfill future
citywide park needs. Thus, when the Citywide Facilities and Improvements Plan (CFIP) was
approved in 1986, Veteran's Memorial Park (then known as Macario Canyon) was
apportioned equally to all four city quadrants to meet the GMP parks performance standard.
Further, the City of Carlsbad Community Facilities District No. 1 (CFD) was established in 1991,
creating a special tax lien on vacant properties throughout the city. The purpose of the CFD
6 "Park District"= "quadrant". There are four park districts within the city, corresponding to the four quadrants.
7 The threshold for triggering the construction of a new park is as follows: Once a deficit of park acreage in a quadrant is identified,
a new park must be scheduled for construction within the time frame of five years. According to City Council Resolution No. 97-435,
"scheduled for construction" means that the improvements have been designed, a park site has been selected, and a financing plan
for construction of the facility has been approved.
16
was to finance the construction of specific public facilities of citywide obligation and benefit,
including Veteran's Memorial Park. Consistent with the intent of the CFIP and the CFD, the
General Plan Open Space, Conservation and Recreation Element credits 22.9 acres of the
91.5-acre Veteran's Memorial Park to each quadrant's future park inventory (see Table 4-7
of the Open Space, Conservation and Recreation Element).
The master planning process for that site commenced in December 2018, with the award of
a professional services agreement to RJM Design, and public outreach began in March
2019. The master plan is scheduled to be completed within the next two years, before the
conclusion of either of the five year periods (i.e., for the SE and SW quadrants, and for the NE
quadrant). Once the master plan is complete, the park will be considered "scheduled for
construction'17, and all four quadrants will be fully compliant with the performance standard.
C. Buildout Facility Adequacy Analysis
Based on the current FY 2017-18 CIP list of projects, Veteran's Memorial Park is proposed to
be constructed prior to buildout. Construction of this community park would result in the
projected park inventory for all city quadrants exceeding the projected required acreage at
buildout, as shown below:
Buildout Buildout Current Proposed park Projected Quadrant required populations acreages inventory acreage inventory
NW 38,606 115.8 105.2 22.9 128.1
NE 22,488 67.5 45.3 22.9 68.2
SW 28,113 84.3 70.2 22.9 93.1
SE 42,315 126.9 114.9 22.9 137.8
Total 131,523 394.6 335.6 91.5 427.2
Additional Parks Acreage
The figures above for proposed park acreage do not include park projects listed in the CIP as
"unfunded" or "partially unfunded": Zone 5 Business Park Recreational Facility (NW -9.3
acres); Cannon Lake Park (NW-6.8 acres); or Robertson Ranch Park (NE-11.2 acres). Should
alternative funding mechanisms be found, and these parks are built, the additional parks
acreage would further aid in meeting/exceeding the growth management parks performance
standard.

DRAINAGE
A. Performance Standard
Drainage facilities must be provided as required by the city concurrent with development.
B. FY 2017-18 Facility Adequacy Analysis
All areas of the city currently meet the growth management drainage performance standard.
The standard for drainage distinguishes it from the other public facility standards because, by
its very nature, drainage facility needs are more accurately assessed as specific development
plans for individual projects are finalized. Therefore, the drainage performance standard was
written to allow the city to require appropriate drainage facilities as development plans are
finalized and approved.
The larger/master plan facilities have been identified in the city's 2008 Drainage Master Plan
and the associated Planned Local Drainage Area (PLDA) fee program was established to
finance their construction. The construction of smaller development/project related
drainage facilities are addressed during the review of individual project proposals.
Maintenance, repair and replacement projects are identified on an ongoing basis and are
incorporated in the Capital Improvement Program as a part of the Corrugated Metal Pipe
Replacement program, the Northwest Quadrant Storm Drain Program or as individual/stand-
alone projects.
The Agua Hedionda and Calavera Creek channels located east of El Camino Real within the
residential community of Rancho Carlsbad were found to be of inadequate size to fully
contain and convey the 100-year flood event. As a result, some of the runoff is conveyed
through the community and therefore projects located within LFMP Zones 5, 7, 14, 15, 16, 18
and 24 that drain to the Agua Hedionda or Calavera Creek must comply with the following
conditions to maintain compliance with the drainage performance standard:
1. Payment of the PLDA fee.
2. Install onsite drainage improvements to ensure that direct drainage impacts resulting
from the proposed development do not exacerbate the potential for downstream
flooding of existing development.
C. Buildout Facility Adequacy Analysis
The 2008 Carlsbad Drainage Master Plan proposes the construction of new facilities to
accommodate potential storm events. Construction of the proposed Master Drainage
Facilities will ensure the drainage performance standard is maintained through buildout of
the city. The 2008 Carlsbad Drainage Master Plan also updated the PLDA program to ensure
adequate funds are available to fund construction of needed flood control facilities. The
estimated costs for these facilities and the programming of PLDA funds are included in the
annual Capital Improvement Program.
18
CIRCULATION
A. Performance Standard
Implement a comprehensive livable streets network that serves all users of the system -
vehicles, pedestrians, bicycles and public transit. Maintain level of service (LOS) D or better
for all modes that are subject to this multi-modal level of service (MMLOS) standard, as
identified in Table 3-1 of the General Plan Mobility Element, excluding LOS exempt
intersections and streets approved by the City Council.
The service levels for each travel mode are represented as a "grade" ranging from LOS A to
LOS F: LOS A reflects a high level of service for a travel mode (e.g. outstanding characteristics
and experience for that mode) and LOS F would reflect an inadequate level of service for a
travel mode · (e.g. excessive congestion for vehicles, inadequate facilities for bicycle,
pedestrian, or transit users).
B. Livable Streets
The California Complete Streets Act (2008) requires cities in California to plan for a balanced,
multi-modal transportation system that meets the needs of all travel modes. Accomplishing
this state mandate requires a fundamental shift in how the city plans and des_igns the street
system -recognizing the street as a public space that serves all users of the system (elderly,
children, bicyclists, pedestrians, etc.) within the urban context of that system (e.g. accounting
for the adjacent land uses).
• Prior to adoption of the General Plan Mobility Element on September 22, 2015, the
growth management circulation performance standard was based on the circulation
needs of a single mode of travel -the automobile.
• The General Plan Mobility Element identifies a new livable streets strategy for mobility
within the city.
• The livable streets strategy focuses on creating a 'multi-modal' street network that
supports the mobility needs of pedestrians, bicyclists, transit users, and vehicles.
• Providing travel mode options that reduce dependence on the vehicle also supports the
city's Climate Action Plan in achieving its goals of reducing greenhouse gas emissions
within the city.
19
C. Street Typology
The city's approach to provide livable streets recognizes that improving the LOS for one mode
of transportation can sometimes degrade the LOS for another mode. For example, pedestrian
friendly streets are designed to encourage pedestrian uses and typically have slow vehicle
travel speeds and short-distance pedestrian crossings that restrict vehicle mobility.
Therefore, the General Plan Mobility Element's livable streets approach identifies, based on
the location and type of street (street typology), the travel modes for which service levels
should be enhanced and maintained per the MM LOS standard (LOS Dor better).
• Mobility Element Table 3-1 describes the livable street typologies and Figure 3-1 depicts
the livable street system.
• The street typology identifies which modes of transportation are subject to, and which
modes are not subject to, the MM LOS standard.
• The vehicle mode of travel is subject to the MM LOS standard only on the following street
typologies: Freeways, Arterial Streets, Arterial Connector Streets, and Industrial Streets.
• The city has historically monitored vehicle LOS along 26 street segments.
o When the Mobility Element was adopted in 2015, eight of those street segments
were designated with street typologies where the vehicle is accommodated but is
not subject to the MM LOS standard.
o These eight street segments are streets where the LOS of other travel modes
(pedestrian, bicycle, transit) is a priority.
o These eight street segments were not monitored for vehicular LOS in this report.
o Vehicular LOS data was collected along the remaining eighteen (26-8=18) street
segments as discussed below.
D. Methods to Measure Multi-Modal Level of Service (MMLOS)
• Vehicle LOS is measured as described below.
• The method to measure pedestrian, bicycle and transit LOS is based on the approach used
in preparation of the General Plan Environmental Impact Report (EIR), which identifies
attributes of a location and identifies a qualitative LOS grade based on the attributes of
the pedestrian, bicycle or transit facility. Each attribute contributes to a point system that,
when the total points for all attributes are added together, corresponds to a qualitative
letter grade. Following the adoption of the General Plan Mobility Element and the
MMLOS standard, city staff developed the MMLOS Tool, which refines the method used
in the General Plan EIR.
20
E. Changing How Vehicle LOS is Measured
During this reporting period, changes were made to how vehicle LOS is measured, in
comparison to previous years. The changes are summarized below and were made to be
consistent with the General Plan Mobility Element, recent changes to the California
Environmental Quality Act (CEQA), and the latest version of the Highway Capacity Manual
(HCM).
• Eliminated intersection vehicle LOS analysis.
The city has historically monitored vehicle LOS using both intersection and street
segment methodologies. The city eliminated the use of intersection LOS analysis and
now evaluates vehicle LOS using only street segment LOS analysis.
• Updated street segment vehicle LOS analysis.
The methodology used to evaluate vehicle LOS along street segments was updated to be
consistent with the Highway Capacity Manual, per the General Plan Mobility Element.
This update resulted in significantly reduced roadway capacities which subsequently led
to significantly lower LOS results on most roadway segments.
• Re-Defined street segments to monitor.
The 18 street segments that were historically monitored and will continue to be
monitored for vehicle LOS have been divided into 43 smaller street segments. Changes
in the number of lanes, signal spacing or speed limit define the segment division. For this
reporting period, traffic counts were not collected for all 43 street segments. Rather,
traffic counts were collected at the same 18 historical locations as in previous years, and
vehicle LOS is reported for the 18 street segments that align with the historical locations.
The other 25 street segments (43-18=25) were not monitored in this report. All 43 street
segments will be monitored in 2019.
• Changing vehicle LOS monitoring from summer conditions to average spring/fall
conditions.
The schedule for collecting field data for vehicle LOS was changed from summer to spring
and fall data collection. The industry standard is to monitor traffic in the spring and fall
to reflect typical conditions when school is in session. This report reflects traffic data
gathered in the fall of 2018.
21
F. LOS D Exemptions
The City Council has the authority to exempt a street facility from the LOS D standard if the
street facility meets one or more of the following criteria from General Plan Mobility Element
Policy 3-P.9:
To exempt the vehicle mode of travel from the LOS standard at a particular street intersection
or segment, the intersection or street segment must be identified as built-out by the City
Council because:
a. Acquiring the rights of way is not feasible; or
b. The proposed improvements would significantly impact the environment in an
unacceptable way and mitigation would not contribute to the nine core values of the
Carlsbad Community Vision; or
c. The proposed improvements would result in unacceptable impacts to other community
values or General Plan policies; or
d. The proposed improvements would require more than three through travel Janes in
each direction.
The following street facilities were identified in the General Plan and are expected to provide
a vehicle level of service below LOS D at buildout. Per General Plan Mobility Element Policy
3-P.10, the following street facilities, including the intersections along these segments, are
exempt from the vehicle level of service standard:
• La Costa Avenue between lnterstate-5 and El Camino Real
• El Camino Real between Palomar Airport Road and La Costa Avenue
• Palomar Airport Road between lnterstate-5 and College Boulevard
• Palomar Airport Road between El Camino Real and Melrose Drive
G. FY 2017-18 Facility Adequacy Analysis
This report includes circulation facility adequacy analysis for FY 2017-18. The details of all
LOS results are found in the 2018 GMP traffic monitoring data. The following table
summarizes the street segments where vehicle and other modes of transportation exceed
(do not meet) the MM LOS standard (LOS Dor higher).
1. Street Segments with Vehicle LOS Exceeding LOS D Standard
Compared to previous growth management monitoring reports, this report identifies
more street segments that do not meet the MMLOS standard -LOS D or higher. The
increase in segments with a LOS below D is primarily due to the changes in how vehicle
22
LOS is measured (as summarized above), and to a lesser degree changes in volume of
vehicles compared to previous years. Following this report, city staff will deliver a more
detailed report to the City Council on the vehicle LOS reported in the table below and
shown in Figure 4.

. H. Buildout Facility Adequacy Analysis
The Environmental Impact Report for the 2015 General Plan evaluated how buildout of the
land uses planned by the General Plan will impact the vehicle, pedestrian, bicycle and transit
levels of service, and identified that additional circulation facilities may need to be
constructed in order to meet the GMP performance standard at buildout. The following
summarizes the results of that evaluation:
Vehicle Level of Service at Buildout
• Additional future road segments (extensions of College Boulevard, Poinsettia Lane and
Camino Junipero) needed to accommodate the city's future growth were identified as
part of the General Plan update. The General Plan Mobility Element identifies these
needed future road segments as "Planned City of Carlsbad Street Capacity
Improvements."
• The General Plan also called out the need to implement the scheduled lnterstate-5 North
Coast Project and lnterstate-S/lnterstate-78 Interchange Improvement Project that are
needed to accommodate future growth.
• The Capital Improvement Program (CIP) funds projects that will upgrade the LOS including
several roadway widenings along El Camino Real near: College Boulevard (northbound),
La Costa Avenue (southbound), and Cassia Road (northbound).
• The General Plan EIR identifies travel demand management (TDM) and traffic system
management (TSM) as mitigation measures for roadway sections that have been given
LOS exemptions.
Pedestrian, Bicycle and Transit Level of Service at Buildout
Improvements to pedestrian, bicycle and transit facilities may be needed to ensure
compliance with the MM LOS standard at buildout. Needed improvements will be identified
after the city has completed an evaluation of the facility according to the roadway typology.
I. Next Steps
Carlsbad Municipal Code 9>21.90.130 (c) states:
If at any time it appears to the satisfaction of the city manager that facilities or
improvements within a facilities management zone or zones are inadequate to
accommodate any further development within that zone or that the performance
standards adopted pursuant to Section 21.90.100 are not being met, he or she shall
immediately report the deficiency to the council. If the council determines that a
deficiency exists, then no further building or development permits shall be issued
within the affected zone or zones and development shall cease until an amendment
25
to the city-wide facilities and improvements plan or applicable local facilities
management plan which addresses the deficiency is approved by the city council and
the performance standard is met.
A staff report will be sent to the City Council that includes the following:
• a list of the street segments subject to the LOS D standard and do not meet this
standard;
• a list of these deficient street segments that meet the conditions for an exemption;
• a list of projects that could be implemented to meet the LOS D standard;
• a request that City Council determine which of these segments is deficient, identify
which ones should gain exemptions, and identify congestion-reducing projects to
fund and expedite in order to meet the LOS D standard.

FIRE
A. Performance Standard
No more than 1,500 dwelling units outside of a five-minute response time.
B. FY 2017-18 Facility Adequacy Analysis
The city's fire facilities are in compliance with the Growth Management performance
standard. There are no more than 1,500 dwelling units outside of a five-minute response
distance from any ofthe city's six fire stations.
The intent of the growth management standard, as applied to fire facilities, is to establish the
number of stations and their locations, based upon response distances. At the time the
Growth Management Plan was developed, scientific fire behavior information and recognized
best practices supported the position that a respon se time of five minutes would result in
effective fire incident intervention. To determine the most desirable geographic sites for
future fire stations, it was necessary to convert the five-minute response time to a
measurable distance that could be applied to a future road network scheme. Because the
Growth Management Plan provides no other trigger mechanism for the installation of
additional fire stations, it follows that up to 1,500 dwelling units could exist outside the five-
minute reach of the closest fire station for an indeterminate length of time without violating
the growth management standard. The five-minute response distance measure was selected
exclusively as a means of logically positioning emergency response resources throughout the
city. Therefore, the standard is applied as a means of measuring compliance with locating
fire facilities in accordance with the Growth Management Plan, not the performance of the
Fire Department in meeting service responsibilities. The growth management fire
performance standard is utilized to determine the number of fire stations and their locations,
not Fire Department response times.
C. Buildout Facility Adequacy Analysis
At buildout, the established threshold of more than 1,500 units that exist outside of a five
minute response distance will not be ~xceeded for any of the fire stations.
To determine if fire facilities will be adequate at buildout, the city's Geographic Information
System Department (GIS) created a map based upon the following information:
• Existing fire station locations
• Anticipated future development
• 2.5-mile road distance from each of the six fire stations (five minute response time
equates to road driving distance of 2.5 miles);
• All planned, major roadway arterials; and
27
• The number of dwelling units projected at buildout that will be located outside of
the 2.5-mile road (5 minute) distance from each fire station.
The GIS map, based upon the above-noted assumptions, revealed the following findings:
Fire Station Number Total number of dwelling units outside of five minutes
1,3 & 4 (aggregated) 1,227
2 902
5 392
6 1,185
As noted above, the GIS map analysis revealed that at build out, the city's existing and
planned fire facilities will meet the growth management performance standard (i.e. the total
number of dwelling units that will exist outside of a five-minute response distance from the
nearest fire station will not exceed the threshold of 1,500 units).
28
OPEN SPACE
A. Performance Standard
Fifteen percent of the total land area in the Local Facility Management Zone (LFMZ) exclusive
of environmentally constrained non-developable land must be set aside for permanent open
space and must be available concurrent with development.
B. FY 2017-18 Facility Adequacy Analysis
To date, adequate open space has been provided to meet the performance standard.
Open space to meet the performance standard is provided concurrent with approval of
development projects. The location of performance standard open space must be indicated
during J:)roject-specific analysis. It must be in addition to any constrained areas, such as
protected wildlife habitat or slopes greater than 40%. At the time the Citywide Facilities and
Improvements Plan was adopted (1986), the LFMZ's were divided into: a) those that were
considered already developed or in compliance with the growth management open space
performance standard, and b) those that still needed to comply with the standard.
a) In 1986 at the time of the CFIP adoption, LFMZs 1 through 10, and 16 were considered
to be already developed or in compliance with the open space performance
standard9•
In addition, Ordinance No. 9808 provided exemptions from the Growth Management
Plan and all of the performance standards for a number of projects that were
approved and/or in process at that time. These projects are also listed in a memo to
the City Manager on June 10, 1986.
In the case of LFMZ 9, the zone boundaries coincide with the project boundaries of
the Batiquitos Lagoon Educational Park Master Plan (MP 175, approved 10-22-1985),
which was exempted from growth management by Section 21.90.030(g) of Ordinance
No. 9808 if certain restrictions were met, including a dedication of open space10• In
anticipation of future construction, the developer of MP 175 dedicated the necessary
open space properties, completing that portion of the requirement for 21.90.030(g)i1.
Although MP 175 ultimately was never constructed, these open space dedications
were maintained and became part of the open space for the project that followed,
9 City Council Resolution No. 8797
10 The restriction for open space required that "Prior to approval of the final map for Phase I the master plan developer
shall have agreed to participate in the restoration of a significant lagoon and wetland resource area and made any
dedications of property necessary to accomplish the restoration".
11 City Council Resolution No. 8666 contained an agreement between the city and the developer for the open space
property dedications noted above.
29
the Poinsettia Shores Master Plan (MP 175(D), approved 01-18-94), and are the basis
for how MP 175(D) and LFMZ 9 complied with the growth management open space
performance standard12.
b) The remaining LFMZs were required to comply with the performance standard.
Subsequent to the adoption of the CFIP, LFMZs 11-15, 17-21, and 23-25 have provided
adequate open space to meet the performance standard concurrent with
development.
LFMZ 22 has not yet met the performance standard, and as future development
· occurs, additional open space will be required.
C. Buildout Facility Adequacy Analysis
As discussed above, all LFMZs, except for Zone 22, have met the growth management open
space performance standard. Future projects in LFMZ 22 must provide open space in
compliance with the performance standard.
12 Poinsettia Shores Master Plan, pages 4 and 22. The master plan states "the Growth Management Open Space
standard is already met for Zone 9 through the earlier preservation of the sensitive bluffs and slopes".

SCHOOLS
A. Performance Standard ·
School capacity to meet projected enrollment within the Local Facility Management Zone
(LFMZ) as determined by the appropriate school dfstrict must be provided prior to projected
occupancy.
B. FY 2017-18 Facility Adequacy Analysis
Currently, school capacity is in compliance with the growth management school performance
standard (see below). The city is served by four school districts as listed below:
1. Carlsbad Unified School District (CUSD)
According to both the district's Long Range Facility Master Plan (approved Jan. 17, 2018)
and CUSD staff, the district can accommodate both the current enrollment levels and
expected future growth. The master plan indicates that the district has plans for
accommodating projected student enrollment levels through the next 15-20 years, which
includes proposals for renovating and replacing a variety of school facilities.
2. San Marcos Unified School District (SMUSD)
SMUSD staff indicated that the schools serving Carlsbad are currently at maximum
capacity, but that will-serve letters are still being issued by SMUSD for proposed
developments in the part of Carlsbad that is served by SMUSD schools, and that the
schools serving Carlsbad could accommodate the expected future growth within this area.
SMUSD is in the construction stage for the La Costa Meadows Elementary School
Reconstruction Project. In addition to reconstructing and modernizing La Costa Meadows
Elementary School, the proposed improvements would increase student capacity by 80 ·
seats. Construction began in May 2017 and completion is anticipated in August 2019.
3. Encinitas Union Elementary School District
According to student enrollment and school capacity information provided by the school
district, sufficient student capacity exists for the 2017-18 school year for schools serving
Carlsbad.
4. San Dieguito Union High School District
According to student enrollment and school capacity information provided by the school
district, sufficient student capacity exists for the 2017-18 school year for schools serving
Carlsbad.
C. Buildout Facility Adequacy Analysis
Based on Chapter 3.11 of the 2015 General Plan EIR, for all school districts at all grade levels,
capacity is expected to be sufficient for the buildout student population with no need for
additional schools.
31
SEWER COLLECTION SERVICES
A. Performance Standard
Trunk-line capacity to meet demand, as determined by the appropriate sewer districts, must
be provided concurrent with development.
B. FY 2017-18 Facility Adequacy Analysis
Sewer improvements are provided on a project by project basis concurrent with
development. Currently, the City of Carlsbad's sewer service area pipelines are in· compliance
with the growth management performance standard. Representatives from the sewer
agencies that provide sewer collection systems within the city include: Carlsbad, Leucadia
Wastewater District and Vallecitos Water District. Each agency indicates that they currently
have adequate conveyance capacity in. place to meet Carlsbad's sewer collection demands.
The City of Carlsbad is served by the following four major interceptor systems:
Interceptor System Sewer Districts Served Carlsbad Capacity Rights13

(3.4% in the upstream reaches as they enter the Carlsbad service area and up to 35% or 50%
in the downstream reaches for Buena Interceptor and Vista/Carlsbad Interceptor,
respectively as they enter the Encina Water Pollution Control Facility).
13 Million gallons per day (MGD)
32
C. Buildout Facility Adequacy Analysis
The 2012 City of Carlsbad Sewer Master Plan evaluated the sewer infrastructure needs of the
Carlsbad sewer service area and identified those facilities required to accommodate future
customers at buildout. The master plan identified the Vista/Carlsbad Interceptor, and Buena
Interceptor as requiring improvements to accommodate build-out demand (see below).
Sewer trunk main capacities are estimated by comparing wastewater flow projections to the
capacity of the sewer system. Using a computer sewer model, the existing and future sewer
demands are estimated and compared to the capacity of each trunk sewer pipeline. In
addition, annual flow measurement information is also used to determine actual flows in the
sewer trunk pipelines.
Vista/Carlsbad Interceptor: A capacity analysis included in the 2012 City of Carlsbad Sewer
Master Plan indicates three relatively flat pipeline portions of Reaches VC13, VC14 & VC15.
As a result, during peak period flows, the pipeline is flowing full. This is an active construction
project, expected to be completed in FY 2018-19. The replacement pipelines are sized based
on ultimate flows from both the City of Carlsbad and City of Vista sewer collection systems.
Buena Interceptor: A capacity analysis conducted in 2010 indicates that although the city's
wastewater flows are not projected to exceed the capacity rights in the Buena Interceptor,
the combined flows of Buena Sanitation District and City of Carlsbad during peak wet weather
periods result in capacity restrictions. As a result, Carlsbad is coordinating with Buena
Sanitation District to construct a parallel trunk sewer which will allow all flows from Buena
Sanitation District to be diverted to the parallel trunk sewer. Once constructed, the City of
Carlsbad will be the only agency with flows remaining in the existing Buena Interceptor, and
this will provide sufficient capacity for Carlsbad during wet weather conditions. Funding for
the design and construction of the parallel trunk sewer was appropriated for FY 2013-14 by
the City of Vista which operates the Buena Sanitation District and is now in the design stage.
Construction is expected to begin in early 2019.
An update to the City of Carlsbad Sewer Master Plan has been initiated and is in the data
collection phase, and the sewer model is currently being updated. The project will provide
an updated evaluati<i>n of sewer infrastructure needs at buildout.

WATER DISTRIBUTION SERVICES
A. Performance Standard
Line capacity to meet demand as determined by the appropriate water district must be
provided concurrent with development. A minimum of 10-day average storage capacity must
be provided prior to any development.
B. FY 2017-18 Facility Adequacy Analysis
Carlsbad's water distribution is provided by three agencies including the Carlsbad Municipal
Water District (CMWD) serving 32.32 square miles {82.7 percent of the city), Olivenhain
Municipal Water District (OMWD) serving 5.28 square miles {13.5 percent of the city), and
Vallecitos Water District (VWD) serving 1.48 square miles (3.8 percent of the city). These
districts indicate that they have adequate capacity to meet the growth management
performance standard.
Water service demand requirements are estimated using a computer model to simulate two
water distribution scenarios: 1) maximum day demand plus a fire event; 2) peak hour
demand. This computer model was calibrated using actual flow measurements collected in
the field to verify it sufficiently represents the actual water system.
Existing and future daily demand and storage requirements for CMWD, which is a subsidiary
district of the City of Carlsbad, from the 2012 CMWD Water Master Plan are shown below:
Water demand Volume14
Existing Maximum Daily Demand 26.7 MGD
Future Maximum Daily Demand 39.4 MGD
Water storage Volume15
Existing Storage Requirement 39.5 MG
Existing Storage Capacity 49 MG excluding Maerkle Dam storage
Based on the water model analysis prepared for the 2012 CMWD Water Master Plan, future
pipelines and water system facilities were identified to ensure a complete water system is
constructed to accommodate future customers. In addition, funds for the construction of
future facilities were included in the FY 2017-18 Capital Improvement Program. Therefore,
the future water infrastructure is programmed to be in place at the time of need in order to
ensure compliance with the performance standard.

Within the CMWD service area the existing average daily potable water demand is shown
below:
Fiscal Year MGD
2008-09 16.5
2009-10 14.2
2010-11 13.2
2011-12 13.7
2012-13 14.4
2013-14 14.9
2014-15 13.6
2015-16 11.4
2016-17 12.1
2017-18 13.4
The lower water demand, compared to the peak of 18.2 MGD in FY 2007-08, is a result of (1)
implementing a new tiered water rate structure to encourage water conservation, (2) in 2009,
a campaign was initiated to reduce customer consumption by the wholesale water agencies,
(3) the persisting drought has forced voluntary and mandatory conservation measures in
2015, and (4) beginning in 2008 an expansion of CMWD's recycled water system lowered
potable water consumption. Water conservation by CMWD customers has resulted in an
overall reduction in per capita consumption.
The 10 day storage requirement, in addition to being a growth management performance
standard, is also required by the San Diego County Water Authority. To meet the
requirement, CMWD needs 131 MG of storage capacity based on the average demand of the
past 5 years. CMWD has a storage capacity of 244 MG which consists of 195 MG of storage
capacity at Maerkle Dam and an additional 49 MG of storage capacity in various storage tanks
throughout the distribution system. CMWD also has interagency agreements with OMWD,
VWD and Oceanside to provide additional supply if needed. In 2004, the OMWD completed
construction of a water treatment facility at the San Diego County Water Authority
Emergency Storage Reservoir, which provides the storage necessary to meet the 10 day
storage requirement for OMWD. VWD's average day demand was 14.6 MGD with an existing
storage capacity of 121.6 MG. Through interagency sharing arrangements VWD can obtain
additional water supplies to meet a 10 day restriction on the imported water supply.
C. Buildout Facility Adequacy Analysis
The 2012 CMWD Water Master Plan identifies facilities necessary for build-out conditions
within its service area. The 2012 update identified that no additional storage tanks are
required to meet the future 10 average-day storage requirements because of a reduction in
demand due to conservation measures and from expansion of CMWD's recycled water
system.

As proposed land development projects are reviewed by the city, the Water Master Plans
from CMWD, OMWD, and VWD are consulted to check pipeline sizes and facility capacities
to verify adequacy to support the water needs of the project and city. To comply with water
master plan requirements, land development projects may be required to install a master
plan water project concurrent with construction of that specific project.
An update to the CMWD Water Master Plan has been initiated and is in the data collection
phase, and the water model is currently being updated. The project will provide an updated
evaluation of water infrastructure needs at buildout.
