A RESOLUTION OF THE CITY COUNCIL OF THE CITY
OF ARROYO GRANDE ADOPTING DEVELOPMENT
IMPACT FEES FOR ALL NEW DEVELOPMENT WITHIN
THE CITY AND TAKING OTHER ACTIONS THERETO
WHEREAS, the City of Arroyo Grande (the "City"), County of San Luis Obispo, State of
California is duly authorized pursuant to the Mitigation Fee Act (the "Act"), commencing
with California Government Code, section 66000 et seq., to impose development impact
fees ("DIF") for purposes defraying all or a portion of the costs of public facilities related
to new development occurring within the City; and
WHEREAS, in accordance with requirements of the Act, the City Council has directed
staff to conduct a comprehensive review of the City's DIF to determine whether those
fees are adequate to defray the cost of public facilities related to new development
projects; and
WHEREAS, the City contracted with Willdan Financial Services to provide a
comprehensive evaluation of the City's existing DIF; and
WHEREAS, Willdan Financial Services prepared a report, entitled 2024 Development
Impact Fee Nexus Study Update (the "Study"), dated January 30, 2024, attached to this

PAGE 2
WHEREAS, the City Council now desires to adopt the proposed DIF, in accordance
with the nexus calculations and recommendations in the Study.
NOW, THEREFORE BE IT RESOLVED that the City Council of the City of Arroyo
Grande hereby finds as follows:
SECTION 1. Incorporation. The above recitals are true and correct and are incorporated
herein by this reference.
SECTION 2. Findings. The City Council finds and determines that the Study, complies
with the Act by establishing the basis for the imposition of fees on new development.
This finding is based on the fact that the Study:
(a) Identifies the purpose of the fee;
(b) Identifies the use to which the fee will be put;
(c) Shows a reasonable relationship between the use of the fee and the
type of development project on which the fee is imposed;
(d) Demonstrates a reasonable relationship between the need for the
public facilities and the type of development projects on which the fee is
imposed; and
(e) Demonstrates a reasonable relationship between the amount of the fee
and the cost of the public facilities or portion of the public facilities
attributable to the development on which the fee is imposed.
SECTION 3. Fees for Uses Consistent with the Study. The City Council hereby
determines that the fees collected pursuant to this Resolution shall be used to finance
the public facilities described or identified in the Study or other such facility plans as
may be proposed, modified, or amended from time to time by the City Council.
SECTION 4. Approval of Items in Development Impact Fee Study. The City Council has
considered the specific project descriptions and cost estimates identified in the Study
and hereby approves such project descriptions and cost estimates and finds them
reasonable as the basis for calculating and imposing certain DIF.
SECTION 5. Differentiation Among Fees. The City Council finds that the fees
recommended in the Study are separate and different from other fees the City may
impose through the implementation of a specific plan or as a condition of final map
approval, building permit issuance or tentative or parcel map approval pursuant to its
authority under the Subdivision Map Act, the Quimby Act, and the City's implementing
resolutions and ordinances, as may be amended from time to time.
In addition, this Resolution shall not be deemed to affect the imposition or collection of
other fees the City is legally authorized to impose and collect.

SECTION 6. CEQA Finding. The City Council finds that this Resolution is exempt from
the California Environmental Quality Act ("CEQA") because this Resolution does not
qualify as a "project" under CEQA and because this Resolution will not result in a direct
or reasonably foreseeable indirect physical change in the environment. (State CEQA
Guidelines section 15060, subd. (c)(2), (3).) Section 15378 of the State CEQA
Guidelines defines a project as the whole of an action, which could potentially result in
either a direct physical change, or reasonably foreseeable indirect physical change, in
the environment. Here, this Resolution will not result in any construction or
development, and it will not have any other effect that would physically change the
environment. This Resolution therefore does not qualify as a project subject to CEQA.
SECTION 7. Adoption of Report. The Study is hereby adopted.
SECTION 8. Amount of Fee. The City Council hereby approves and adopts the DIF as
set forth in Exhibit "A" to this Resolution, attached hereto and incorporated herein by
this reference. Exhibit "A" sets forth the aggregate amount imposed as a DIF for
development projects and also sets forth the breakdown of each DIF by category type.
The DIF set forth in Exhibit "A" are consistent with the Study. The amount of the DIF
shall be modified annually to account for inflation each January 1 based on the change
in the Engineering News Record, California Construction Cost Index each year. Such
inflationary increases shall not constitute an increase within the meaning of the Act and
may be implemented each year without the requirement to obtain approval of the City
Council.
SECTION 9. Prior Resolutions Superseded. The DIF approved by this Resolution
supersede previously adopted resolutions that set the amounts of DIF.
SECTION 10. Severability. If any action, subsection, sentence, clause or phrase of this
Resolution or the imposition of the DIF for any project described in the Study or the
application thereof to any person or circumstance shall be held invalid or
unconstitutional by a court of competent jurisdiction, such invalidity shall not affect the
validity of the remaining portions of this Resolution or other DIF levied by this Resolution
that can be given effect without the invalid provisions or application of the DIF.
SECTION 11. Effective Date. Consistent with the Act, the DIF as identified in attached
Exhibit "A" adopted by this Resolution shall take effect on April 15, 2024, a period
longer than the required sixty (60) days following the adoption of this Resolution by the
City Council.
SECTION 12. Records. The documents and materials associated with this Resolution
that constitute the record of proceedings on which the City Council's findings and
determinations are based are located at 300 E. Branch Street, Arroyo Grande, CA
93420. The City Clerk is the custodian of the record of proceedings.
PASSED AND ADOPTED by the City Council of the City of Arroyo Grande this 13th day
of February 2024 by the following vote:

Executive Summary
This report summarizes an analysis of development impact fees needed to support future
development in the City of Arroyo Grande through 2050. It is the City's intent that the costs
representing future development's share of public facilities and capital improvements be imposed
on that development in the form of a development impact fee, also known as a public facilities
fee. The public facilities and improvements included in this analysis are divided into the fee
categories listed below:
■ Fire Protection Facilities ■ Water Facilities
• Police Facilities • Transportation Facilities
■ Park Facilities ■ Storm Drain Facilities
• Recreation Facilities • Wastewater Facilities
Background n Objectives
The primary policy objective of a development impact fee program is to ensure that new
development pays the capital costs associated with growth. Although growth also imposes
operating costs, there is not a similar system to generate revenue from new development for
services. The primary purpose of this report is to calculate and present fees that will enable the
City to expand its inventory of public facilities, as new development creates increases in service
demands.
The City collects public facilities fees under authority granted by the Mitigation Fee Act (the Act),
contained in California Government Code Sections 66000 et seq. This report provides the
necessary findings required by the Act for adoption of the fees presented in the fee schedules
contained herein.
The City programs development impact fee-funded capital projects through its Capital
Improvement Plan (CIP). Using a CIP allows the City to identify and direct its fee revenue to
public facilities projects that will accommodate future growth. By programming fee revenues to
specific capital projects, the City can help ensure a reasonable relationship between new
development and the use of fee revenues as required by the Mitigation Fee Act.
Facility Standards
There are three approaches used to calculate facilities standards and allocate the costs of
planned facilities to accommodate growth in compliance with the Mitigation Fee Act requirements
in this study.
The existing inventory approach is based on a facility standard derived from the City's existing
level of facilities and existing demand for services. This approach results in no facility deficiencies
attributable to existing development. This approach is often used when a long-range plan for new
facilities is not available. Future facilities to serve growth will be identified through the City's
annual CIP and budget process and/or completion of a new facility master plan. This approach is
used to calculate the fire protection, police, parks and recreation facility fees in this report.
The planned facilities approach allocates costs based on the ratio of planned facilities that serve
new development to the increase in demand associated with new development. This approach is
appropriate when specific planned facilities that only benefit new development can be identified,
or when the specific share of facilities benefiting new development can be identified. Examples
include street improvements to avoid deficient levels of service or a sewer trunk line extension to
a previously undeveloped area. This approach is used for the water, transportation, storm drain
and wastewater facilities fees in this report.
WILLDAN 1
..._.., FiN.C,At.SFNVIC'F5
City of Arroyo Grande Development Impact Fee Nexus Study Update
The system plan approach is based on a master facility plan in situations where specific needed
facilities serve both existing and new development. This approach allocates existing and planned
facilities across existing and new development to determine new development's fair share of
facility needs. This approach is used when it is not possible to differentiate the benefits of new
facilities between new and existing development. This approach is not used in this report.
Use of Fee Revenues
Impact fee revenue must be spent on new facilities or expansion of current facilities to serve new
development. Facilities can be generally defined as capital acquisition items with a useful life
greater than five years. Impact fee revenue can be spent on capital facilities to serve new
development, including but not limited to land acquisition, construction of buildings, construction
of infrastructure, the acquisition of vehicles or equipment, information technology, software
licenses and equipment.
In that the City cannot predict with certainty how and when development within the City will occur
during the planning horizon assumed in this study, the City may need to update and revise the
project lists funded by the fees documented in this study. Any substitute projects should be
funded within the same facility category, and the substitute projects must still benefit and have a
relationship to new development. The City could identify any changes to the projects funded by
the impact fees when it updates the CIP. The impact fees could also be updated if significant
changes to the projects funded by the fees are anticipated.
Development Impact
Table E.1 summarizes the development impact fees that meet the City's identified needs and
comply with the requirements of the Mitigation Fee Act. Table E.2 displays the maximum justified
water facilities impact fee schedule.

Other Funding
Impact fees may only fund the share of public facilities related to new development in Arroyo
Grande. They may not be used to fund the share of facility needs generated by existing
development or by development outside of the City. As shown in Table E.3, approximately $4
million in additional funding will be needed to complete the facility projects the City currently plans
to develop if fees are adopted at the maximum justified fee level. The "Additional Funding
Required" column shows non-impact fee funding required to fund a share of the improvements
partially funded by impact fees. Non-fee funding is needed because these facilities are needed
partially to remedy existing deficiencies and partly to accommodate new development. To the
extent that the City adopts fees that are lower than the maximum justified amount, the non-fee
funding requirements may increase, depending on the fee category and methodology.
The City will need to develop alternative funding sources to fund existing development's share of
the planned facilities. Potential sources of revenue include but are not limited to existing or new
general fund revenues, existing or new taxes, special assessments, and grants.

Introduction
f
This report presents an analysis of the need for public facilities to accommodate new
development in the City of Arroyo Grande. This chapter provides background for the study and
explains the study approach under the following sections:
• Public Facilities Financing in California;
• Study Objectives;
• Fee Program Maintenance;
• Study Methodology; and
• Organization of the Report.
Public Facilities Financing in lifri
The changing fiscal landscape in California during the past 45 years has steadily undercut the
financial capacity of local governments to fund infrastructure. Three dominant trends stand out:
■ The passage of a string of tax limitation measures, starting with Proposition 13 in
1978 and continuing through the passage of Proposition 218 in 1996;
• Declining popular support for bond measures to finance infrastructure for the next
generation of residents and businesses; and
■ Steep reductions in federal and state assistance.
Faced with these trends, many cities and counties have had to adopt a policy of"growth pays its
own way." This policy shifts the burden of funding infrastructure expansion from existing
ratepayers and taxpayers onto new development. This funding shift has been accomplished
primarily through the imposition of assessments, special taxes, and development impact fees also
known as public facilities fees. Assessments and special taxes require the approval of property
owners and are appropriate when the funded facilities are directly related to the developing
property. Development impact fees, on the other hand, are an appropriate funding source for
facilities that benefit all development jurisdiction-wide. Development impact fees need only a
majority vote of the legislative body for adoption.
Study b ti
The primary policy objective of a public facilities fee program is to ensure that new development
pays the capital costs associated with growth. The primary purpose of this report is to update the
City's existing impact fees based on the most current available facility plans and growth
projections. The maximum justified fees will enable the City to expand its inventory of public
facilities as new development leads to increases in service demands.
The City collects public facilities fees under authority granted by the Mitigation Fee Act (the Act),
contained in California Government Code Sections 66000 et seq. This report provides the
necessary findings required by the Act for adoption of the fees presented in the fee schedules
presented in this report.
Arroyo Grande is forecast to see significant growth through this study's planning horizon of 2050.
This growth will create an increase in demand for public services and the facilities required to
deliver them. Given the revenue challenges described above, Arroyo Grande has decided to
continue to use a development impact fee program to ensure that new development funds its
share of facility costs associated with growth. This report makes use of the most current available
W I t_t_DAN
,:AFv, fs
City of Arroyo Grande Development Impact Fee Nexus Study Update
growth forecasts and facility plans to update the City's existing fee program to ensure that the fee
program accurately represents the facility needs resulting from new development.
Fee Program Maintenance
Once a fee program has been adopted it must be properly maintained to ensure that the revenue
collected adequately funds the facilities needed by new development. To avoid collecting
inadequate revenue, the inventories of existing facilities and costs for planned facilities must be
updated periodically for inflation, and the fees recalculated to reflect the higher costs. The use of
established indices for each facility included in the inventories (land, buildings, and equipment),
such as the California Construction Cost Index, is necessary to accurately adjust the impact fees.
For a list of recommended indices, see Chapter 12.
While fee updates using inflation indices are appropriate for annual or periodic updates to ensure
that fee revenues keep up with increases in the costs of public facilities, it is recommended to
conduct more extensive updates of the fee documentation and calculation (such as this study)
when significant new data on growth forecasts and/or facility plans become available. For further
detail on fee program implementation, see Chapter 12.
Study the y
Development impact fees are calculated to fund the cost of facilities required to accommodate
growth. The six steps followed in this development impact fee study include:
1. Estimate existing development and future growth: Identify a base year for
existing development and a growth forecast that reflects increased demand for public
facilities;
2. Identify facility standards: Determine the facility standards used to plan for new
and expanded facilities;
3. Determine facilities required to serve new development: Estimate the total
amount of planned facilities, and identify the share required to accommodate new
development;
4. Determine the cost of facilities required to serve new development: Estimate the
total amount and the share of the cost of planned facilities required to accommodate
new development;
5. Calculate fee schedule: Allocate facilities costs per unit of new development to
calculate the development impact fee schedule; and
6. Identify alternative funding requirements: Determine if any non-fee funding is
required to complete projects.
The key public policy issue in development impact fee studies is the identification of facility
standards (step #2, above). Facility standards document a reasonable relationship between new
development and the need for new facilities. Standards ensure that new development does not
fund deficiencies associated with existing development.
Types of Facility Standards
There are three separate components of facility standards:
• Demand standards determine the amount of facilities required to accommodate
growth, for example, park acres per thousand residents, square feet of library space
per capita, or gallons of water per day. Demand standards may also reflect a level of
service such as the vehicle volume-to-capacity(V/C)ratio used in traffic planning.

ieN&NC,At SERVICES
City of Arroyo Grande Development Impact Fee Nexus Study Update
• Design standards determine how a facility should be designed to meet expected
demand, for example, park improvement requirements and technology infrastructure
for City office space. Design standards are typically not explicitly evaluated as part of
an impact fee analysis but can have a significant impact on the cost of facilities. Our
approach incorporates the cost of planned facilities built to satisfy the City's facility
design standards.
• Cost standards are an alternate method for determining the amount of facilities
required to accommodate growth based on facility costs per unit of demand. Cost
standards are useful when demand standards were not explicitly developed for the
facility planning process. Cost standards also enable different types of facilities to be
analyzed based on a single measure (cost or value) and are useful when different
facilities are funded by a single fee program. Examples include facility costs per
capita, cost per vehicle trip, or cost per gallon of water per day.
New Development Facility Needs and Costs
A number of approaches are used to identify facility needs and costs to serve new development.
This is often a two-step process: (1) identify total facility needs, and (2) allocate to new
development its fair share of those needs.
There are three common methods for determining new development's fair share of planned
facilities costs in this study: the existing inventory method, the planned facilities method, and
the system plan method. Often the method selected depends on the degree to which the
community has engaged in comprehensive facility master planning to identify facility needs.
The formula used by each approach and the advantages and disadvantages of each method is
summarized below:
Existing Inventory Method
The existing inventory method allocates costs based on the ratio of existing facilities to demand
from existing development as follows:
Current Value of Existing Facilities
= cost per unit of demand
Existing Development Demand
Under this method new development will fund the expansion of facilities at the same standard
currently serving existing development. The existing inventory method results in no facility
deficiencies attributable to existing development. This method is often used when a long-range
plan for new facilities is not available. Future facilities to serve growth are identified through an
annual CIP and budget process, possibly after completion of a new facility master plan. This
approach is used to calculate the fire protection, police, parks, and recreation facility fees in this
report.
Planned Facilities Method
The planned facilities method allocates costs based on the ratio of planned facility costs to
demand from new development as follows:
Cost of Planned Facilities
=cost per unit of demand
New Development Demand
This method is appropriate when planned facilities will entirely serve new development, or when a
fair share allocation of planned facilities to new development can be estimated.An example of the
former is a Wastewater trunk line extension to a previously undeveloped area. An example of the
latter is expansion of an existing library building and book collection, which will be needed only if
new development occurs, but which, if built, will in part benefit existing development, as well.
Under this method new development will fund the expansion of facilities at the standards used in
8
WILLOAN
City of Arroyo Grande Development Impact Fee Nexus Study Update
the applicable planning documents. This approach is used for the water, transportation, storm
drain and wastewater facilities fees in this report.
System Plan Method
This method calculates the fee based on the value of existing facilities plus the cost of planned
facilities, divided by demand from existing plus new development:
Value of Existing Facilities+ Cost of Planned Facilities
Existing + New Development Demand =cost per unit of demand
This method is useful when planned facilities need to be analyzed as part of a system that
benefits both existing and new development. It is difficult, for example, to allocate a new fire
station solely to new development when that station will operate as part of an integrated system
of fire stations that together achieve the desired level of service.
The system plan method ensures that new development does not pay for existing deficiencies.
Often facility standards based on policies such as those found in Comprehensive Plans are
higher than the existing facility standards. This method enables the calculation of the existing
deficiency required to bring existing development up to the policy-based standard. The local
agency must secure non-fee funding for that portion of planned facilities required to correct the
deficiency to ensure that new development receives the level of service funded by the impact fee.
This approach is not used in this report.
Organization of the Report
The determination of a public facilities fee begins with the selection of a planning horizon and
development of growth projections for population and employment. These projections are used
throughout the analysis of different facility categories and are summarized in Chapter 2.
Chapters 3 through 10 identify facility standards and planned facilities, allocate the cost of
planned facilities between new development and other development, and identify the appropriate
development impact fee for each of the following facility categories:
■ Fire Protection Facilities • Water Facilities
• Police Facilities • Transportation Facilities
• Park Facilities • Storm Drain Facilities
■ Recreation Facilities • Wastewater Facilities
Chapter 11 describes how this nexus study complies with the requirements of AB 602.
Chapter 12 details the procedures that the City must follow when implementing a development
impact fee program. Impact fee program adoption procedures are found in California Government
Code Sections 66016 through 66018.
The five statutory findings required for adoption of the maximum justified public facilities fees in
accordance with the Mitigation Fee Act are documented in Chapter 13.

Growth Forecasts
Growth projections are used as indicators of demand to determine facility needs and allocate
those needs between existing and new development. This chapter explains the source for the
growth projections used in this study based on a 2023 base year and a planning horizon of 2050.
Estimates of existing development and projections of future growth are critical assumptions used
throughout this report. These estimates are used as follows:
• The estimate of existing development in 2023 is used as an indicator of existing
facility demand and to determine existing facility standards.
• The estimate of total development at the 2050 planning horizon is used as an
indicator of future demand to determine total facilities needed to accommodate
growth and remedy existing facility deficiencies, if any.
• Estimates of growth from 2023 through 2050 are used to (1) allocate facility costs
between new development and existing development, and (2) estimate total fee
revenues.
The demand for public facilities is based on the service population, dwelling units or
nonresidential development creating the need for the facilities.
Land Use Types
To ensure a reasonable relationship between each fee and the type of development paying the
fee, growth projections distinguish between different land use types. The land use types for which
impact fees have been calculated for are defined below.
• Residential Dwelling Units: All residential dwelling units, including detached and
attached one-unit dwellings and all multifamily dwellings including apartments,
duplexes and condominiums.
• Commercial: All commercial, retail, educational, and service development.
• Office: All general, professional, and medical office development.
Some developments may include more than one land use type, such as a mixed-use
development with both multifamily and commercial uses. In those cases, the facilities fee would
be calculated separately for each land use type.
The City has the discretion to determine which land use type best reflects a development
project's characteristics for purposes of imposing an impact fee and may adjust fees for special or
unique uses to reflect the impact characteristics of the use. If a project results in the
intensification of use, at its discretion, the City can charge the project the difference in fees
between the existing low intensity use and the future high intensity use.
Impact Fees for Accessory Dwelling Units
The California State Legislature recently amended requirements on local agencies for the
imposition of development impact fees on accessory dwelling units (ADU) with Assembly Bill AB
68 in 2021. The amendment to California Government Code §65852.2(f)(2) stipulates that local
agencies may not impose any impact fees on ADU less than 750 square feet. ADU greater than
750 square feet can be charged impact fees in proportion to the size of the primary dwelling unit.
Calculating Impact Fees for Accessory Dwelling Units
For ADUs greater than 750 square feet, impact fees can be charged as a percentage of the
single family impact fee. The formula is:
10
W I LLDAN
FALAN,I AL Scfi V:CFS
City of Arroyo Grande Development Impact Fee Nexus Study Update
ADU Square Feet
x Single Family Impact Fee = ADU Impact Fee
Primary Residence Square Feet
In the case of an 800 square foot ADU and a 1,600 square foot primary residence, the impact
fees would be 50 percent (800 square feet / 1,600 square feet = 50%) of the single family
dwelling unit fee.
Existing and FutureDevelopment
Table 2.1 shows the estimated number of residents, dwelling units, employees, and building
square feet in Arroyo Grande, both in 2023 and in 2050. The base year estimates of household
residents and dwelling units comes from the California Department of Finance (DOF). The 2050
projection of residents was identified in the "Meduim" growth scenario from the SLOCOG 2050
Regional Growth Forecast. The regional growth forecast projected 8,460 households in 2050.
Accounting for 7% vacancy (which is the current vacancy rate reported by the DOF), the
projection totals an increase of 1,016 housing units. It assumes that the same ratio of single
family to multifamily will be maintained as development occurs.
Base year employees were estimated based on the latest data from the US Census' OnTheMap
application and exclude 187 local government (public administration) employees. Total projected
workers in 2050 are identified the regional growth forecast. The proportion of workers by land use
is held consistent with current estimates. The estimates of nonresidential building square feet
were estimated by dividing employee counts by the occupancy density factors presented in the
following table.

Occupant Densities
All fees in this report are calculated based on dwelling units or building square feet. Occupant
density assumptions ensure a reasonable relationship between the size of a development project,
the increase in service population associated with the project, and the amount of the fee.
Occupant densities (residents per dwelling unit or workers per building square foot) are the most
appropriate characteristics to use for most impact fees. The fee imposed should be based on the
land use type that most closely represents the probable occupant density of the development.
The occupancy factors are shown in Table 2.2. The residential density factors are based on data
for Arroyo Grande from the 2021 U.S. Census' American Community Survey, the most recent
data available. The nonresidential occupancy factors are derived from data from the Institute of
Traffic Engineers Trip Generation Manual, 11th Edition.

3. Fire Protection Facilities
The purpose of this fee is to ensure that new development funds its fair share of fire protection
facilities. A fee schedule is presented based on the existing facilities standard of fire protection
facilities in the City of Arroyo Grande to ensure that new development provides adequate funding
to meet its needs.
Service i tion
Fire protection facilities serve both residents and businesses. Therefore, demand for services and
associated facilities are based on the City's service population including residents and workers.
Table 3.1 shows the existing and future projected service population for fire protection facilities.
While specific data is not available to estimate the actual ratio of demand per resident to demand
by businesses (per worker) for this service, it is reasonable to assume that demand for these
services is less for one employee compared to one resident, because nonresidential buildings are
typically occupied less intensively than dwelling units. The 0.31-weighting factor for workers is
based on a 40-hour workweek divided by the total number of non-work hours in a week(128)and
reflects the degree to which nonresidential development yields a lesser demand for police
facilities.

Authority to increase staffing and service capacity as the City grows.
Cost Allocation
Table 3.3 expresses the City's current fire facilities level of service in terms of an existing cost per
capita, by dividing the replacement cost of the City's existing facilities by the existing service
population. The resulting cost per capita drives the fee calculation. The cost per capita is
multiplied by the worker weighting factor to determine the cost per worker.

Fee Revenue Projection
The City plans to use fire protection facilities fee revenue to construct improvements and acquire
capital facilities and equipment to add to the system of fire facilities to serve new development.

Sources:Tables 3.1 and 3.4.
Fee Schedule
Table 3.5 shows the maximum justified fire protection facilities fee schedule. The City can adopt
any fee up to this amount. The cost per capita is converted to a fee per unit of new development
based on dwelling unit and employment densities (persons per dwelling unit or employees per
1,000 square feet of nonresidential building space). The fee per dwelling unit is converted into a
fee per square foot by dividing the fee per dwelling unit by the assumed average square footage
of a dwelling unit.
The total fee includes a two percent (2.0%) administrative charge to fund costs that include: a
standard overhead charge applied to City programs for legal, accounting, and other departmental
and administrative support, and fee program administrative costs including revenue collection,
revenue and cost accounting and mandated public reporting.
In Willdan's experience with impact fee programs, two percent of the base fee adequately covers
the cost of fee program administration. The administrative charge should be reviewed and
adjusted during comprehensive impact fee updates to ensure that revenue generated from the
charge sufficiently covers, but does not exceed, the administrative costs associated with the fee
program.

Park ility Standards
Park facility standards establish a reasonable relationship between new development and the
need for expanded park facilities. Information regarding the City's existing inventory of existing
parks facilities was obtained from City staff.
The most common measure in calculating new development's demand for parks is the ratio of
park acres per resident. In general, facility standards may be based on a jurisdiction's existing
inventory of park facilities, or an adopted policy standard contained in a master facility plan or
general plan. Facility standards may also be based on a land dedication standard established by
the Quimby Act.1
Quimby Act Standard
The Quimby Act specifies that the dedication requirement must be a minimum of 3.0 acres and a
maximum of 5.0 acres per 1,000 residents. A jurisdiction can require residential developers to
dedicate above the three-acre minimum if the jurisdiction's existing park standard at the time it
adopted its Quimby Act ordinance justifies the higher level (up to five acres per 1,000 residents).
The standard used must also conform to the jurisdiction's adopted general or specific plan
standards.
The Quimby Act only applies to land subdivisions. The Quimby Act would not apply to residential
development on future approved projects on single parcels, such as apartment complexes and
other multifamily development.
The Quimby Act allows payment of a fee in lieu of land dedication. The fee is calculated to fund
acquisition of the same amount of land that would have been dedicated.
The Quimby Act allows use of in-lieu fee revenue for any park or recreation facility purpose.
Allowable uses of this revenue include land acquisition, park improvements including recreation
facilities, and rehabilitation of existing park and recreation facilities. The Quimby Act generally
requires that fees be used for neighborhood and community park acreage to serve the
subdivision, except in limited circumstances.

City of Arroyo Grande Park Facilities Standards
Table 5.4 shows the existing standard for improved park acreage per 1,000 residents based on
the type of parkland. In total the City has an existing parkland standard of 2.97 acres per 1,000
residents, which is less than the minimum Quimby standard of 3.0 acres per 1,000 residents..
The impact fee analysis in this report will be based on maintaining the City's 2.97 acre per 1,000
resident standard as new development adds demand for parks in Arroyo Grande. Fees in-lieu of
land dedication for subdivisions are calculated at the minimum Quimby standard of 3.0 acres of
developed parkland per 1,000 residents.
Table 5.4 also shows the City's existing open space standard. This is calculated separately from
the parkland standard. The current open space standard is 4.23 acres per 1,000 residents.

Facilities to ccs t
Table 5.5 shows the park facilities needed to accommodate new development at the existing
standard. To achieve the standard by the planning horizon, depending on the amount of
development subject to the Quimby Act, new development must fund the purchase and
improvement of between 8.05 and 8.13 parkland acres.
The facility standards and resulting fees under the Quimby Act are higher because development
will be charged to provide 3.0 acres of parkland per 1,000 residents, and 2.97 acres of
improvements, whereas development not subject to the Quimby Act will be charged to provide
only 2.97 acres of parkland and improvements per 1,000 residents. Since the exact amount of
development that will be subject to the Quimby fees is unknown at this time, Table 5.5 presents
the range of total facility costs that may be incurred depending on the amount of development
subject to the Quimby Act.
Table 5.5 also displays the cost necessary to maintain the City's existing open space standard.
The City would need to acquire 11.46 acres of open space to maintain this standard.

Use of Fee Revenue
The City plans to use park and recreation facilities fee revenue to purchase parkland and open
space and construct improvements to add to the system of park facilities that serves new
development. The City may only use impact fee revenue to provide facilities and intensify usage
of existing facilities needed to serve new development. The City should program fee revenue to
capacity expanding projects annually through its CIP and budget process.
Fee Schedule
To calculate fees by land use type, the investment in park facilities is determined on a per
resident basis for parkland acquisition, open space acquisition and parkland improvements.
These investment factors(shown in Table 5.6)are based on the unit cost estimates and the City's
existing facility standards.
Table 5.7 shows the maximum justified park and recreation facilities fee based on the existing
standard per capita under the Quimby Act and under the existing park standard under the
Mitigation Fee Act, respectively. The cost per resident is converted to a fee per dwelling unit
using the occupancy density factor from Table 2.2. The fee per dwelling unit is converted into a
fee per square foot by dividing the fee per dwelling unit by the assumed average square footage
of a dwelling unit.
The total fee includes a two percent (2.0%) administrative charge to fund costs that include: a
standard overhead charge applied to City programs for legal, accounting, and other departmental
and administrative support, and fee program administrative costs including revenue collection,
revenue and cost accounting and mandated public reporting.
In Willdan's experience with impact fee programs, two percent of the base fee adequately covers
the cost of fee program administration. The administrative charge should be reviewed and
adjusted during comprehensive impact fee updates to ensure that revenue generated from the
charge sufficiently covers, but does not exceed, the administrative costs associated with the fee
program.

The purpose of this fee is to ensure that new development funds its fair share of recreation
facilities. A fee schedule is presented based on the existing facilities standard of recreation
facilities in the City of Arroyo Grande to ensure that new development provides adequate funding
to meet its needs.
Service tion
Park facilities in Arroyo Grande primarily serve residents. Therefore, demand for services and
associated facilities is based on the City's residential population. Table 6.1 shows the existing
and future projected service population for recreation facilities.

T Water Facilities
This chapter details an analysis of the need for water facilities to accommodate growth within the
City of Arroyo Grande. The projects and associated costs in this chapter were identified in the
City's Water System Master Plan. This chapter documents a reasonable relationship between
new development and a water facilities impact fee to fund facilities that serve new development.
Water Demand
Estimates of new development and its consequent increased water demand provide the basis for
calculating the water facilities fee. The need for water facilities improvements is based on the
water demand placed on the system by development. A typical measure of demand is a flow
generation rate, expressed as the number of gallons per day generated by a specific type of land
use. Flow generation rates are a reasonable measure of demand for the City's system of water
improvements because they represent the average rate of demand that will be placed on the
system per land use designation.
Table 7.1 shows the calculation of equivalent dwelling unit(EDU) demand factors based on flow
generation by land use category. The residential flow generation estimates are based on 2023
actual usage data from the City. The nonresidential flow generation factors per acre are based on
data from the City's Water System Master Plan. EDU factors express water flow from each land
use in terms of the flow generated by a single family dwelling unit.

Table 7.3 identifies the planned water facilities to be funded by the fee. Project costs from the
2012 Water System Master Plan have been adjusted for inflation into 2023 dollars, using the
Engineering News Record's Construction Cost Index (CCI). Those projects that have already
been completed, or that do not benefit new development have been excluded from the table.
Projects that are needed to serve both existing and new development are allocated to the impact
fee based on the increase in capacity associated with each improvement. For project C-3, the
impact fee is allocated a portion of the costs based on new development's share of EDUs in 2050
(12.3%), identified in Table 7.2. Projects that are needed solely to serve new development are
allocated 100%to new development through this impact fee.

The maximum justified fee for water facilities is shown in Table 7.5. The cost per EDU is
converted to a fee per unit of new development based on capacity of a 1" meter relative to the
capacity of other meter sizes. Using water meter size to drive the fee schedule is reasonable and
directly proportional to the amount of water that can be accommodated by a connection.
The total fee includes a two percent (2.0%) administrative charge to fund costs that include: a
standard overhead charge applied to City programs for legal, accounting, and other departmental
and administrative support, and fee program administrative costs including revenue collection,
revenue and cost accounting and mandated public reporting.

8Transportation Facilities
a
This chapter details an analysis of the need for transportation facilities to accommodate new
development. The chapter documents a reasonable relationship between new development and
the impact fee for funding of these facilities.
Trip Demand
The need for transportation facilities is based on the trip demand placed on the system by
development. A reasonable measure of demand is the number of average daily vehicle trips,
adjusted for the type of trip. Vehicle trip generation rates are a reasonable measure of demand on
the City's system of street improvements across all modes because alternate modes (transit,
bicycle, pedestrian)often substitute for vehicle trips.
The two types of trips adjustments made to trip generation rates to calculate trip demand are
described below:
• Pass-by trips are deducted from the trip generation rate. Pass-by trips are
intermediates stops between an origin and a destination that require no diversion
from the route, such as stopping to get gas on the way to work.
■ The trip generation rate is adjusted by the average length of trips for a specific land
use category compared to the average length of all trips on the street system.
These adjustments allow for a holistic quantification of trip demand that takes trip purpose
and length into account for fee calculation purposes.
Table 8.1 shows the calculation of trip demand factors by land use category based on the
adjustments described above. Data is based on extensive and detailed trip surveys
conducted in the Institute of Traffic Engineers (ITE), and by the San Diego Association of
Governments (SANDAG). The trip rates and pass-by trip assumptions come from ITE. The
trip length assumptions come from SANDAG. The surveys provide some of the most
comprehensive databases available of trip generation rates, pass-by trips factors, and
average trip length for a wide range of land uses.

City of Arroyo Grande Development Impact Fee Nexus Study Update
Fee per Trig Demand Unit
Every impact fee consists of a dollar amount, representing the value of facilities, divided by a
measure of demand. In this case, all fees are first calculated as a cost per trip demand unit. Then
these amounts are translated into housing unit (cost per unit) and employment space (cost per
1,000 square feet or room)fees by multiplying the cost per trip by the trip generation rate for each
land use category. These amounts become the fee schedule.
Table 8.4 displays the calculation of the cost the cost per trip demand unit. The project costs
allocated to new development are divided by the increase in trip demand from 2023 to 2050 from
Table 8.2 to determine the cost per trip attributable to new development. This figure drives the fee
calculation.
Table 8.4: Cost per Trip to Accommodate Growth
Costs Allocated to New Development $ 11,539,440
Growth in Trip Demand (2023 to 2050) 2,850
Cost per Trip $ 4,049
Sources:Tables 8.2 and 8.3.
Fee Schedule
Table 8.5 shows the maximum justified transportation facilities fee schedule. The City can adopt
any fee up to these amounts. The maximum justified fees are based on the cost per trip identified
in. Table 8.4. The cost per trip is multiplied by the trip demand factors in Table 8.1 to determine a
fee per unit of new development. The fee per dwelling unit is converted into a fee per square foot
by dividing the fee per dwelling unit by the assumed average square footage of a dwelling unit.
The total fee includes a two percent (2.0%) administrative charge to fund costs that include: a
standard overhead charge applied to City programs for legal, accounting, and other departmental
and administrative support, and fee program administrative costs including revenue collection,
revenue and cost accounting and mandated public reporting.
In Willdan's experience with impact fee programs, two percent of the base fee adequately covers
the cost of fee program administration. The administrative charge should be reviewed and
adjusted during comprehensive impact fee updates to ensure that revenue generated from the
charge sufficiently covers, but does not exceed, the administrative costs associated with the fee
program.

9. Storm Drain Facilities
This chapter summarizes an analysis of the need for storm drain facilities to accommodate
growth within Arroyo Grande. This projects and associated costs in this chapter were identified it
the City's CIP from the FY2023-25 Biennial Budget. This chapter documents a reasonable
relationship between new development and an impact to fund storm drain facilities that serve new
development.
Storm i Demand
Most new development generates storm water runoff that must be controlled through storm drain
facilities by increasing the amount of land that is impervious to precipitation. Table 9.1 shows the
calculation of equivalent dwelling unit (EDU) demand factors based on impervious surface
coefficient by land use category. The impervious surface coefficients are based data from the
California Environmental Protection Agency. EDU factors relate demand for storm drain facilities
in terms of the demand created by a single-family dwelling unit.

Facilities
This chapter details an analysis of the need for wastewater facilities to accommodate growth
within the City of Arroyo Grande. This projects and associated costs in this chapter were
identified it the City's Wastewater System Master Plan, 2012. It documents a reasonable
relationship between new development and an impact fee to fund wastewater facilities that serve
new development.
Wastewater Demand
Estimates of new development and its consequent increased wastewater demand provide the
basis for calculating the wastewater facilities fee. The need for wastewater facilities
improvements is based on the wastewater demand placed on the system by development. A
typical measure of demand is a flow generation rate, expressed as the number of gallons per day
generated by a specific type of land use. Flow generation rates are a reasonable measure of
demand on the City's system of wastewater improvements because they represent the average
rate of demand that will be placed on the system per land use designation.
Table 10.1 shows the calculation of equivalent dwelling unit(EDU) demand factors based on flow
generation by land use category. The water flow generation estimates used in Chapter 7 are
multiplied by a return flow rate of 51% based on City data to estimate the amount of wastewater
flow, by land use. EDU factors express water flow from each land use in terms of the flow
generated by a single family dwelling unit.

Table 10.2 shows the estimated EDU generation from new development through 2050. The EDU
factors from Table 10.1 are multiplied by the land use assumptions from Table 2.1 to estimate
total EDUs in the base year, at the planning horizon and for new development. New development
will generate 1,132 new EDU5 through 2050, comprising 12.3%of wastewater demand in the City
at that time.

11 . AB 602 Requirements
On January 1, 2022, new requirements went into effect for California jurisdictions implementing
impact fees. Among other changes, AB 602 added Section 66016.5 to, the Government Code,
which set guidelines for impact fee nexus studies. Four key requirements from that section which
concern the nexus study are reproduced here:
66016.5. (a) (2) When applicable, the nexus study shall identify the existing level of service for
each public facility, identify the proposed new level of service, and include an explanation of why
the new level of service is appropriate.
66016.5. (a) (4) If a nexus study supports the increase of an existing fee, the local agency shall
review the assumptions of the nexus study supporting the original fee and evaluate the amount of
fees collected under the original fee.
66016.5. (a) (5) A nexus study adopted after July 1, 2022, shall calculate a fee imposed on a
housing development project proportionately to the square footage of proposed units of the
development. A local agency that imposes a fee proportionately to the square footage of the
proposed units of the development shall be deemed to have used a valid method to establish a
reasonable relationship between the fee charged and the burden posed by the development.
66016.5. (a) (6) Large jurisdictions shall adopt a capital improvement plan as a part of the nexus
study.
Compliance with
The following sections describe this study's compliance with the new requirements of AB 602.
66016.5. (a) (2) - Level of Service
1. For fees calculated under the existing standard methodology, the fees are calculated such that
new development funds facilities at the existing level of service. These fee categories are: fire
protection, police, parks and recreation. The existing level service in terms of the existing facility
cost per capita is shown in each corresponding chapter.
2. For fees calculated under the planned facilities methodology, the fees are calculated to ensure
that the level of service does not fall to unacceptable levels and are based on Citywide facility
master planning documents. The fees calculated under this approach are the water,
transportation, storm drain and wastewater facilities impact fees.
66016.5. (a) (4) — Review of Original Fee Assumptions
The original fee schedules and corresponding revenue generated were reviewed by the City and
Willdan prior to conducting the nexus study analysis. The planning and cost assumptions from the
City's prior Impact Fee Study (2000), were out of date and in need of update. Table 11.1
summarizes the review of the prior impact fee study's assumptions. Table 11.2 displays annual
fee revenue collected, by impact fee fund.

City of Arroyo Grande Development Impact Fee Nexus Study Update
66016.5. (a) (5) — Residential Fees per Square Foot
Impact fees for residential land uses are calculated per square foot for all fee categories except
for water facilities and comply with AB 602. Water facilities fees are calculated based on the
water meter size, which scales based on the capacity accommodated by different sized meters.
Thus the water facilities fees are proportionate to the burden placed on the water system by new
development.
66016.5. (a) (6) — Capital Improvement Plan
A description of the planned facilities that the City expects to fund with impact fee revenue is
included in each chapter in this report. Adoption of this nexus study would approve the planned
facilities identified herein as the Capital Improvement Plan for this nexus study.

12. Implementation
Impact Fee ProgramAdoption Process
Impact fee program adoption procedures are found in the California Government Code section
66016. Adoption of an impact fee program requires the City Council to follow certain procedures
including holding a public hearing. Data, such as an impact fee report, must be made available at
least 10 days prior to the public hearing. The City's legal counsel should be consulted for any
other procedural requirements as well as advice regarding adoption of an enabling ordinance
and/or a resolution. After adoption there is a mandatory 60-day waiting period before the fees go
into effect.
Inflation tart
The City can keep its impact fee program up to date by periodically adjusting the fees for inflation.
Such adjustments should be completed regularly to ensure that new development will fully fund
its share of needed facilities. We recommend that the California Construction Cost Index
(https://www.dgs.ca.gov/RESD/Resources/Page-Content/Real-Estate-Services-Division-
Resources-List-Folder/DGS-California-Construction-Cost-Index-CCCI) be used for adjusting fees
for inflation. The California Construction Cost Index is based on data from the Engineering News
Record and is aggregated and made available for free by the State of California.
The fee amounts can be adjusted based on the change in the index compared to the index in the
base year of this study(2023).
While fee updates using inflation indices are appropriate for periodic updates to ensure that fee
revenues keep up with increases in the costs of public facilities, the City will also need to conduct
more extensive updates of the fee documentation and calculation (such as this study) when
significant new data on growth forecasts and/or facility plans become available. Note that
decreases in index value will result in decreases to fee amounts.
Reporting Requirements
The City will comply with the annual and five-year reporting requirements of the Mitigation Fee
Act. For facilities to be funded by a combination of public fees and other revenues, identification
of the source and amount of these non-fee revenues is essential. Identification of the timing of
receipt of other revenues to fund the facilities is also important.
There is no time limit by which impact fee revenue must be spent. However, if the City is accruing
impact fee revenue to fund new development's share of a project, then it must make certain
findings with respect to unexpended impact fee fund balances after five years. Among other
requirements, the five-year report requires the City to"Identify all sources and amounts of funding
anticipated to complete financing in incomplete improvements," and to "Designate the
approximate dates on which supplemental funding is expected to be deposited into the
appropriate account or fund."2
On October 13, 2023 AB 516 was signed into law by the Governor of California, and will go into
effect on January 1,2024. This the bill requires local agencies to:

City of Arroyo Grande Development Impact Fee Nexus Study Update
• Include information on projects noted in prior reports and whether construction began on
the approximate date noted,in the previous report.
• Explain the reason for any delay in the start of the project and provide a new approximate
date construction will begin.
• Identify the number of people or entities that receive refunds of Mitigation Fee Act fees.
The bill also requires local agencies to inform people paying mitigation fees that they:
• Can request an audit to determine if the fees charged by a local agency are more than
the amount of money needed to cover the cost of the public improvements.
• Can receive information by mail about when the local agency will meet to review its
annual Mitigation Fee Act report.
• Can access and review mitigation fee information on the local agency's website, and how
to do so.
Table 12.1 summarizes the annual and five-year reporting requirements identified in the
Mitigation Fee Act.

Programming Ravenues and Projects with the CIP
The City maintains a Capital Improvement Program (CIP) to plan for future infrastructure needs.
The CIP identifies costs and phasing for specific capital projects. The use of the CIP in this
manner documents a reasonable relationship between new development and the use of those
revenues.
The City may decide to alter the scope of the planned projects or to substitute new projects if
those new projects continue to represent an expansion of the City's facilities and provide benefit
to new development. If the total cost of facilities varies from the total cost used as a basis for the
fees, the City should consider revising the fees accordingly.

13. Mitigation Findings
Public facilities fees are one-time fees typically paid when a building permit is issued and
imposed on development projects by local agencies responsible for regulating land use (cities
and counties). To guide the widespread imposition of public facilities fees the State Legislature
adopted the Mitigation Fee Act (the Act) with Assembly Bill 1600 in 1987 and subsequent
amendments. The Act, contained in California Government Code Sections 66000 through 66025,
establishes requirements on local agencies for the imposition and administration of fee programs.
The Act requires local agencies to document five findings when adopting a fee.
The five statutory findings required for adoption of the public facilities fees documented in this
report are presented in this chapter and supported in detail by the preceding chapters. All
statutory references are to the Act.
Purpose of Fee
■ Identify the purpose of the fee (§66001(a)(1) of the Act).
Development impact fees are designed to ensure that new development will not burden the
existing service population with the cost of facilities required to accommodate growth. The
purpose of the fees documented by this report is to provide a funding source from new
development for capital improvements to serve that development. The fees advance a legitimate
City interest by enabling the City to provide public facilities for new development.
Use of Fee Revenues
• Identify the use to which the fees will be put. if the use is financing facilities, the facilities
shall be identified. That identification may, but need not, be made by reference to a
capital improvement plan as specified in §65403 or§66002, may be made in applicable
general or specific plan requirements, or may be made in other public documents that
identify the facilities for which the fees are charged(§66001(a)(2)of the Act).
Fees documented in this report, if enacted by the City, would be used to fund expanded facilities
to serve new development. Facilities funded by these fees are designated to be located within the
City's sphere of influence. Fees addressed in this report have been identified by the City to be
restricted to funding the following facility categories: fire protection, police, parks, recreation,
water,transportation, storm drain and wastewater facilities.
Benefit Relationship
■ Determine the reasonable relationship between the fees' use and the type of
development project on which the fees are imposed(§66001(a)(3)of the Act).
The City will restrict fee revenue to the acquisition of land, construction of facilities, infrastructure
and buildings, and purchase of related equipment, furnishings, vehicles, and services used to
serve new development. Facilities funded by the fees are expected to provide a citywide network
of facilities accessible to the additional residents and workers associated with new development.
Under the Act, fees are not intended to fund planned facilities needed to correct existing
deficiencies. Thus, a reasonable relationship can be shown between the use of fee revenue and
the new development residential and non-residential use classifications that will pay the fees.

City of Arroyo Grande Development Impact Fee Nexus Study Update
Burden Relationship
■ Determine the reasonable relationship between the need for the public facilities and the
types of development on which the fees are imposed(§66001(a)(4) of the Act).
Facilities need is based on a facility standard that represents the demand generated by new
development for those facilities. For each facility category, demand is measured by a single
facility standard that can be applied across land use types to ensure a reasonable relationship to
the type of development. For some facility categories service population standards are calculated
based upon the number of residents associated with residential development and the number of
workers associated with non-residential development. To calculate a single, per capita standard,
one worker is weighted differently than one resident based on an analysis of the relative use
demand between residential and non-residential development.
The standards used to identify growth needs are also used to determine if planned facilities will
partially serve the existing service population by correcting existing deficiencies. This approach
ensures that new development will only be responsible for its fair share of planned facilities, and
that the fees will not unfairly burden new development with the cost of facilities associated with
serving the existing service population.
Chapter 2, Growth Forecasts provides a description of how service population and growth
forecasts are calculated. Facility standards are described in the Facility Standard sections of each
facility category chapter.
Proportionality
Determine how there is a reasonable relationship between the fees amount and the cost
of the facilities or portion of the facilities attributable to the development on which the fee
is imposed(§66001(b) of the Act).
The reasonable relationship between each facilities fee for a specific new development project
and the cost of the facilities attributable to that project is based on the estimated new
development growth the project will accommodate. Fees for a specific project are based on the
project's size. Larger new development projects can result in a higher service population resulting
in higher fee revenue than smaller projects in the same land use classification. Thus, the fees
ensure a reasonable relationship between a specific new development project and the cost of the
facilities attributable to that project.
See Chapter 2, Growth Forecasts, or the Service Population sections in each facility category
chapter for a description of how service populations or other factors are determined for different
types of land uses. See the Fee Schedule section of each facility category chapter for a
presentation of the maximum justified facilities fees.
