Project Description:
In order to comply with the new California laws, Assembly Bill 2299 and Senate Bill 1069, which
took effect on January 2017 amending the state law governing second dwelling units, California
cities and counties are required to adopt or amend their local ordinances in compliance with the
new state law. Regulatory barriers are reduced for the construction of accessory dwelling units
such as reductions or exemptions from parking requirements and reduced utility connection fees
for second units. A set of standards apply for second units created within an existing residential
structure and another set for new second units, attached or detached, that create additional living
space. Accessory dwelling units are regulated by Section 9.60.090, Second Residential Units of the
La Quinta Municipal Code. The City Attorney and staff conducted a consistency analysis of
existing Code with the new state laws and recommend certain code amendments.
The standards of the Second Residential Units, Section 9.60.090, are proposed to be modified as
follows:
• Replace references to Second Residential Units with references to Accessory Dwelling
Units.
• Establishes new standards for accessory dwelling units within existing primary structure
and units not within existing structures
• Require accessory dwelling unit permitting as a ministerial process
• No requirement for new or separate utility connection for accessory dwelling units
proposed within an existing primary structure.
• Parking spaces for new accessory dwelling units can be provided as tandem parking,
including on an existing driveway or in setback areas, excluding the non -driveway front
yard setback.
• Parking requirements for the primary dwelling must be met before the approval an
accessory dwelling unit.

Significance
On the basis of this initial evaluation:
X I find that the proposed project COULD NOT have a significant effect on the environment, and
a NEGATIVE DECLARATION will be prepared.
I find that although the proposed project could have a significant effect on the environment,
there will not be a significant effect in this case because revisions in the project have been made
by or agreed to by the project proponent. A MITIGATED NEGATIVE DECLARATION will
be prepared.
I find that the proposed project MAY have a significant effect on the environment, and an
ENVIRONMENTAL IMPACT REPORT is required.
I find that the proposed project MAY have a "potentially significant impact" or "potentially
significant unless mitigated" impact on the environment, but at least one effect 1) has been
adequately analyzed in an earlier document pursuant to applicable legal standards, and 2) has
been addressed by mitigation measures based on the earlier analysis as described on attached
sheets. An ENVIRONMENTAL IMPACT REPORT is required, but it must analyze only the
effects that remain to be addressed.
I find that although the proposed project could have a significant effect on the environment,
because all potentially significant effects (a) have been analyzed adequately in an earlier EIR or
NEGATIVE DECLARATION pursuant to applicable standards, and (b) have been avoided or
mitigated pursuant to that earlier EIR or NEGATIVE DECLARATION, including revisions or
mitigateasures that are imposed upon the proposed project, nothing further is required.

EVALUATION OF ENVIRONMENTAL IMPACTS:
1) A brief explanation is required for all answers except "No Impact" answers that are adequately
supported by the information sources a lead agency cites in the parentheses following each
question. A "No Impact" answer is adequately supported if the referenced information sources
show that the impact simply does not apply to projects like the one involved (e.g., the project
falls outside a fault rupture zone). A "No Impact" answer should be explained where it is
based on project -specific factors as well as general standards (e.g., the project will not expose
sensitive receptors to pollutants, based on a project -specific screening analysis).
2) All answers must take account of the whole action involved, including off-site as well as on-
site, cumulative as well as project -level, indirect as well as direct, and construction as well as
operational impacts.
3) Once the lead agency has determined that a particular physical impact may occur, then the
checklist answers must indicate whether the impact is potentially significant, less than
significant with mitigation, or less than significant. "Potentially Significant Impact" is
appropriate if there is substantial evidence that an effect may be significant. If there are one or
more "Potentially Significant Impact" entries when the determination is made, an EIR is
required.
4) "Negative Declaration: Less Than Significant With Mitigation Incorporated" applies where
the incorporation of mitigation measures has reduced an effect from "Potentially Significant
Impact" to a "Less Than Significant Impact." The lead agency must describe the mitigation
measures, and briefly explain how they reduce the effect to a less than significant level
(mitigation measures from Section XVII, "Earlier Analyses," may be cross-referenced).
5) Earlier analyses may be used where, pursuant to the tiering, program EIR, or other CEQA
process, an effect has been adequately analyzed in an earlier EIR or negative declaration.
Section 15063(c)(3)(D). In this case, a brief discussion should identify the following:
a) Earlier Analysis Used. Identify and state where they are available for review.
b) Impacts Adequately Addressed. Identify which effects from the above checklist were
within the scope of and adequately analyzed in an earlier document pursuant to
applicable legal standards, and state whether such effects were addressed by mitigation
measures based on the earlier analysis.
C) Mitigation Measures. For effects that are "Less than Significant with Mitigation
Measures Incorporated," describe the mitigation measures, which were incorporated or
refined from the earlier document and the extent to which they address site-specific
conditions for the project.
6) Lead agencies are encouraged to incorporate into the checklist references to information
sources for potential impacts (e.g., general plans, zoning ordinances). Reference to a
previously prepared or outside document should, where appropriate, include a reference to the
page or pages where the statement is substantiated.
7) Supporting Information Sources: A source list should be attached, and other sources used or
individuals contacted should be cited in the discussion.
8) This is only a suggested form, and lead agencies are free to use different formats; however,
lead agencies should normally address the questions from this checklist that are relevant to a
project's environmental effects in whatever format is selected.
9) The explanation of each issue should identify:
a) the significance criteria or threshold, if any, used to evaluate each question; and
go

VIII. HAZARDS AND HAZARDOUS
MATERIALS --Would theproject:
a) Create a significant hazard to the
public or the environment through the
X
routine transport, use, or disposal of
hazardous materials?
b) Create a significant hazard to the
public or the environment through
reasonably foreseeable upset and accident
X
conditions involving the release of
hazardous materials into the
environment?
c) Emit hazardous emissions or handle
hazardous or acutely hazardous materials,
X
substances, or waste within one-quarter
mile of an existing or proposed school?
d) Be located on a site which is included
on a list of hazardous materials sites
compiled pursuant to Government Code
X
Section 65962.5 and, as a result, would it
create a significant hazard to the public or
the environment?
e) For a project located within an airport
land use plan or, where such a plan has
not been adopted, within two miles of a
public airport or public use airport, would
X
the project result in a safety hazard for
people residing or working in the project
area?
f) For a project within the vicinity of a
private airstrip, would the project result in
X
a safety hazard for people residing or
working in the project area?
g) Impair implementation of or physically
interfere with an adopted emergency
X
response plan or emergency evacuation
plan?

significant risk of loss, injury or death
involving wildland fires, including where
X
wildlands are adjacent to urbanized areas
or where residences are intermixed with
wildlands?
Source: 2035 General Plan, CA Department of Toxic Substances, project materials.
VII. a) -d) No Impact. The zoning ordinance amendment will not result in any impact associated with
hazards or hazardous materials. The construction and operation of accessory dwelling units in
the future will not create a significant hazard to the public related to the transportation of
hazardous materials. Small amounts of chemicals for household cleaning may be transported
or stored by homeowners; however, they will be minimal and cause similar risks as those
associated with existing residential uses in the area. The current residences and future
accessory dwelling units will generate use, storage, or transport of hazardous materials.
However, the regulations of the Fire Department, County Department of Environmental
Health and State and federal agencies will apply. These standard requirements will ensure that
no impacts associated with the use, storage, or transport of hazardous materials occur.
The proposed zoning ordinance amendment will not create a significant hazard to the public
or environment through reasonably foreseeable upset and accident conditions involving the
release of hazardous materials into the environment. Future construction and operation of
accessory dwelling units will be similar to exiting residential use of hazardous materials. No
impact will occur.
e -g) No Impact. The City is located west of the Jacqueline Cochran Regional Airport and south of
the Bermuda Dune Regional Airport. The zoning ordinance amendment will not create
hazards associated with aviation. The proposed zoning ordinance amendment will not
physically interfere with local or regional roadway networks, or interfere with implementation
of an emergency response or evacuation plan. Future developments will have access to the
City's existing street grid for emergency purposes. No impacts are expected.
h) No Impact. The City is located on the valley floor, and is in a highly urbanized area. There
will be no impacts associated with wildland fires.
Mitigation: None.
Monitoring: None.

IX. HYDROLOGY AND WATER
QUALITY -- Would the project:
a) Violate any water quality standards or
X
waste discharge requirements?
b) Substantially deplete groundwater
supplies or interfere substantially with
groundwater recharge such that there
would be a net deficit in aquifer volume or
a lowering of the local groundwater table
X
level (e.g., the production rate of pre-
existing nearby wells would drop to a level
which would not support existing land uses
or planned uses for which permits have
been granted)?
c) Substantially alter the existing drainage
pattern of the site or area, including
through the alteration of the course of a
X
stream or river, in a manner which would
result in substantial erosion or siltation on -
or off-site?
d) Substantially alter the existing drainage
pattern of the site or area, including
through the alteration of the course of a
stream or river, or substantially increase the
X
rate or amount of surface runoff in a
manner which would result in flooding on -
or off-site?
e) Create or contribute runoff water which
would exceed the capacity of existing or
planned stormwater drainage systems or
X
provide substantial additional sources of
polluted runoff?
f) Place housing within a 100 -year flood hazard
area as mapped on a federal Flood Hazard
Boundary or Flood Insurance Rate Map or
X
other flood hazard delineation map?
g) Place within a 100 -year flood hazard area
structures which would impede or redirect

IX. a) No Impact. The zoning ordinance amendment will have no impact on water quality
standards. Coachella Valley Water District (CVWD) provides domestic water to residences
in the City. CVWD implements all water pollution standards required, assuming that water
sources are not contaminated, either during construction or operation. Future accessory
dwelling units will continue to control storm water flows as it has, based on City standards.
b) No Impact. The zoning ordinance amendment will have no impact on water supply.
Coachella Valley Water District (CVWD) will supply domestic water to future accessory
dwelling units. CVWD has prepared an Urban Water Management Plan 2010 Update, which
is a long-term document that facilitates the planning for current and future water demands.
The UWMP demonstrates that the District has available, and can supply, sufficient water to
serve the potential expansion due to the proposed zoning ordinance amendment, insofar as the
amendment would not result in substantial numbers of additional units. Water use for future
accessory units will be required to comply with CVWD's and the City's water -efficiency
requirements.
c) -g) No Impact. The zoning ordinance amendment will have no impact on flooding. It is not likely
that La Quinta will be affected by a tsunami because the City is located approximately 60
miles from the Pacific coast. Future units will be required to implement City standards
relating to flooding hazards. For this reason, no impact would occur.
Mitigation: None required.
Monitoring: None required.

X. a) No Impact. The zoning ordinance amendment will not divide an established community for
the reason that any potential construction will be limited to existing residential units in
existing neighborhoods. No impact is expected.
b) Less Than Significant Impact. In order to comply with the new state law, AB 2299, which
among other elements, makes a number of changes to the Accessory Dwelling Unit (ADU)
review process and standards in order to ease some of the barriers to the development, the
City is required to implement these amendments. As a result, the City has limited latitude in
its review of these documents. In terms of conformance with the General Plan, second
dwelling units are allowed within single family residential zones. The proposed zoning
ordinance amendment would have the potential to increase the number of units allowed on a
lot, but does allow limitations in terms of new units. That is to say that the City does not have
to permit additional structures under this ordinance if the density of the lot would be
exceeded. This will result in self -limitations in density increases, although the conversion of
interior space in an existing home could still occur. Additionally, the zoning ordinance
amendment does keep in place parking requirements for the primary unit, while allowing
accessory units to have less parking. As a result, the primary unit's garage, or a replacement
garage, must be available, and cannot be lost to the accessory unit.
c) No Impact. Any construction and future development will occur on previously disturbed
residential areas and will not be located within any conservation areas as identified in the
CVMSHCP (See IV e -f). No impact will occur.

The nearest airport, Jacqueline Cochran Regional Airport, is located southeast of the City. Although
there is potential for an occasional overflight, existing dwelling units and future accessory units will
not impact air traffic patterns.
Fire Department standards ensure that emergency access will be created and preserved for the future
accessory units.
Prior to the approval of an accessory dwelling unit the existing residence must comply with two
covered parking spaces or a two -car garage. This will ensure that the existing residence is in
compliance with the City's parking requirement as well as providing sufficient parking
accommodations in the form of tandem parking in the driveway for the accessory dwelling units.

c) Does the project have impacts that are
individually limited, but cumulatively
considerable? ("Cumulatively
considerable" means that the incremental
effects of a project are considerable when
X
viewed in connection with the effects of
past projects, the effects of other current
projects, and the effects of probable

effects which will cause substantial
X
adverse effects on human beings, either
-31-
EA 2017-0005
ZOA 2017-0001

directly or indirectly?
XVIII. a) -d) No Impact. The zoning ordinance amendment will not impact either biological or
cultural resources. The future development of accessory units will occur on existing
residential lots which have been fully disturbed. There will be no impact to biological or
cultural resources.
The proposed zoning ordinance amendment is required to meet State law. It will not impact
environmental goals, because accessory structures will occur on existing single family lots,
and will reduce the potential for sprawl.
The zoning ordinance amendment has no impacts which could be cumulatively significant,
because the ordinance amendment will not result in any development. Future accessory units
built under the terms of the ordinance amendment would not be expected to result in sufficient
numbers, because of the City's development standards relating to building coverage and
parking, to cause cumulative impacts.
The zoning ordinance amendment will have no impact on human beings.

Government Code Section 65852.2. Accessory dwelling units shall be permitted only in
the RVL, RL, RC, RM, RMH, and RH zone districts.
B. Definitions. See Chapter 9.280. For purposes of this section, "second residential
unit," "second dwelling unit," "second unit," and "granny flat" as defined in Section
9.280.030 (or successor section) shall not apply, and, instead, "accessory dwelling unit"
as defined in California Government Code Section 65852.2(i)(4) (or successor section
in the Government Code) shall apply. An accessory dwelling unit shall be either
"attached" or "detached" to the primary residence as described in Government Code
Section 65852.2(i)(4) (or successor statute). In addition, the following definitions shall
apply for purposes of this section:
1. "Living area" shall have the same meaning as California Government Code Section
65852.2(i)(1) (or successor section in the Government Code), notwithstanding any
provision in Section 9.280.030 of this code to the contrary.
2. "Primary residence" shall have the same meaning as "Dwelling, single-family
detached" or "single-family detached dwelling" as defined in Section 9.280.030 (or
successor section).
3. "Public transit" means public mass transit that has a major transit stop or bus stop
along a high-quality transit corridor as described in California Public Resources Code
Section 21155(b) (or successor statute).
C. Standards for Accessory Dwelling Units. Subject to allowances set forth in
Subsection D, the following standards shall apply to accessory dwelling units:
1. An accessory dwelling unit shall be consistent with the provisions of the applicable
zoning district in which it is constructed.
2. An accessory dwelling unit shall only be permitted on a lot in which the primary
residence and all other structures thereon conform to all minimum requirements of the
applicable zoning district.
3. The lot shall contain an existing primary residence at the time an application for an
accessory dwelling unit is submitted, or the application for the accessory dwelling unit
may be made in conjunction with the development of the primary residence.
4. The owner of the lot shall reside on the lot, either in the primary residence or in the
accessory dwelling unit. Prior to issuance of occupancy approval of the accessory
dwelling unit, the city may require the property owner to enter into a restrictive covenant
with the city regarding such owner -occupancy requirement on a form prepared by the
city, which shall be recorded against the lot. Such covenant shall further provide that the

::I:I 1:1 11 i:?
accessory dwelling unit shall not be sold, or title thereto transferred separate from that
of the lot or the primary residence. If the owner ceases to reside on the lot, use of the
accessory dwelling unit shall be discontinued as follows: (a) if it is an attached
accessory dwelling unit, the unit shall be converted into a portion of the primary
residence; or, (b) if it is a detached accessory dwelling unit, the unit shall be removed or
converted to a legal use. The city manager or authorized designee may grant temporary
relief from this owner -occupancy requirement.
5. The maximum increase in gross floor area of an attached accessory dwelling unit
shall not exceed fifty percent of the existing living area of the primary residence or one
thousand two hundred square feet, whichever is less.
6. The minimum gross floor area of an accessory dwelling unit shall be four hundred
square feet, except that the minimum gross floor area of an accessory dwelling unit that
qualifies as an efficiency unit under California Health and Safety Code Section 17958.1
(or successor statute) shall be one hundred fifty square feet. The maximum gross floor
area of a detached accessory dwelling unit shall not exceed thirty percent of the existing
living area of the primary residence or one thousand two hundred square feet,
whichever is less.
7. An accessory dwelling unit shall have no more than two bedrooms.
8. The total gross floor area of all covered structures, including an attached accessory
dwelling unit, shall not exceed the lot coverage area as prescribed by the applicable
zoning district.
9. The accessory dwelling unit shall be architecturally compatible with the primary
residence and surrounding residential neighborhood. If a dispute arises whether the
accessory dwelling unit is architecturally compatible with the primary residence, review
of the application for the accessory dwelling unit shall be processed as any other design
review application under the code but limited to the determination of architectural
compatibility. For purposes of this section, "architecturally compatible" means that the
accessory dwelling unit generally has the same or substantially similar architectural
style, construction and structure materials, paint pallet or scheme, and other prominent
design features, as the primary residence.
10. No attached accessory dwelling unit shall cause the height of the primary residence
to exceed the height limitation for the applicable zoning district. If the attached
accessory dwelling unit is not located above any portion of an existing primary
residence, the maximum height of the accessory dwelling unit shall not exceed the
height of the primary residence.
11. A detached accessory dwelling unit shall not exceed seventeen feet in height nor
more than one story.

12. An attached accessory dwelling unit may have a separate entrance; provided,
however, in no event shall any external stairwell be placed within the front or side yard
setback.
13. An accessory dwelling unit shall contain separate kitchen and bathroom facilities,
and shall be metered separately from the primary residence for gas, electricity,
communications, water, and sewer services.
14. All attached and detached accessory dwelling units shall be equipped with approved
smoke detectors conforming to the latest Uniform Building Code standards, mounted on
the ceiling or wall at a point centrally located in an area giving access to rooms used for
sleeping purposes.
15. In addition to the required parking for the primary residence, a minimum of one
additional off-street parking space shall be provided on the same lot that the accessory
dwelling unit is located. One parking space shall be provided for each efficiency unit as
defined under California Health and Safety Code Section 17958.1 (or successor statute)
in accordance with the applicable parking regulations. Subject to the allowances in
Subsection D, no variance or adjustment shall be granted to allow substandard parking
spaces or locations.
16. All construction, structural alterations or additions made to create an accessory
dwelling unit shall comply with current building, electrical, fire, plumbing and zoning
code regulations.
17. In the event of any conflicts between the standards set forth in this section and
those set forth in the regulations of the applicable zoning district, the provisions of this
section shall prevail.
18. The applicant shall pay to the city all applicable fees imposed on such new
development of an accessory dwelling unit or new or rehabilitated primary residence
that will include an accessory dwelling unit.
19. The city manager or authorized designee may add other conditions, consistent with
general law and applicable state and city standards, as necessary to preserve the
health, safety, welfare and character of the residential neighborhood; provided,
however, that such conditions shall not unreasonably restrict the ability of an applicant
to create an accessory dwelling unit.
D. Allowances for Qualifying Accessory Dwelling Units. In accordance with California
Government Code Section 65852.2, as amended by Section 1.5 of Chapter 735 of the
Statutes of 2016, the following allowances apply for qualifying accessory dwelling units.
1. Parking requirement exemptions. If one or more of the following criteria is met: (a) a
proposed accessory dwelling unit is located within one-half mile of public transit, (b) a
proposed accessory dwelling unit is located within an architecturally and historically
698/015610-0002
10999115.3 a07/06/17 _ 3 _
EXHIBIT B
significant historic district, (c) a proposed accessory dwelling unit is part of an existing
primary residence or existing accessory structure, (d) the occupant of a proposed
accessory dwelling unit would be required to obtain an on -street parking permit from the
city, or (e) a proposed accessory dwelling unit is located within one block of a car -share
vehicle station or parking area; then the applicant for an accessory dwelling unit may be
exempted from the parking requirements under the zone for which the proposed
accessory dwelling unit is located. Nothing in this subsection, however, exempts the
primary residence from complying with all parking requirements under the zone for
which the proposed accessory dwelling unit is located. Furthermore, nothing in this
subsection exempts the owner of the lot from complying with all parking requirements
for fire safety, including access to the lot by front and rear setbacks that are to be clear
of obstructions.
2. Utility Connection exemptions. If all of the following criteria are met: (a) a proposed
accessory dwelling unit is contained in the existing primary residence or existing
accessory structure, (b) a proposed accessory dwelling unit has independent exterior
access from the existing primary residence pursuant to this section, and (c) the side and
rear setbacks are sufficient for fire safety as determined by the zoning and public safety
provisions in this code; then the applicant for an accessory dwelling unit may be
exempted from the requirement to install a new or separate utility connection directly
between the accessory dwelling unit and the utility, and may be exempted from related
connection fees or capacity charges. The city may require, however, that the owner of
the lot on which the proposed accessory dwelling unit is located to pay any such
connection fees or capacity charges as part of the primary residence. Furthermore, the
city may require, as part of the restrictive covenant to be recorded against the lot
pursuant to this section, that the owner of the lot implement a metering system that
would account for the percentage use of each utility provided to an accessory dwelling
unit compared to total use of that utility for the of entire lot, and that all utilities that are
provided to the accessory dwelling unit be metered by the utilities provided to the
primary residence. Any metering system implemented by the owner of the lot pursuant
to this subsection shall be subject to verification by the utility from which the service is
being provided to the accessory dwelling unit.
3. For purposes of this Subsection D, "existing accessory structure" means "accessory
building or structure" as defined in Section 9.280.030 that exists on the lot with an
existing primary residence at the time of submittal for any application relating to the
proposed accessory dwelling unit.
E. If an application for an accessory dwelling unit is submitted or required to be
submitted with any other applications that require or permit ministerial or discretionary
review under the code, nothing in this section precludes the processing and review of
those other applications pursuant to those other provisions in the code.
