MEMORANDUM
To: Chair Tucker and the Housing Element Update Advisory Committee
From: David Barquist, AICP
Kimley Horn and Associates, Inc
Date: February 12, 2021
Subject: Newport Beach Regional Housing Needs Assessment (RHNA) Sites Inventory
This Memorandum provides a summary of potential scenarios to accommodate the City’s RHNA growth
need. The Housing Element Update Advisory Committee’s initial identification of sites is utilized as a
basis for the analysis contained herein. It should be noted that this analysis is for discussion purposes
only and the methodology, unit data and other planning assumptions are subject to change. The intent
of this Memorandum is to provide a summary of the RHNA Sites Inventory process and proposed
strategies to meet the RHNA Allocation.
RHNA ALLOCATION & SITES CRITERIA
The City of Newport Beach 2021-2029 RHNA Allocation was determined by the Southern California
Association of Governments (SCAG) and assigns an allocation of housing units, categorized by income
category, that the City of Newport Beach (the City) must plan to accommodate during the 2021-2029
planning period.
City of Newport Beach
2021-2029 RHNA Growth Need Allocations
Income Category Affordability (1) Dwelling Units
Very Low 0 – 50% County MFI 1,453 units
Low 51 – 80% County MFI 928 units
Moderate 81% - 120% County MFI 1,048 units
Above Moderate >120% County MFI 1,405 units
TOTAL 4,834 units
Notes: (1) Based on percentage of Orange County Median Family Income (MFI), updated annually. The
2020 MFI for a four-person household is $103,000.
HCD Criteria & Considerations for Sites Designated for Low and Very-Low Income Units
Within the Sites Inventory Guidebook, HCD specifies additional criteria needed to support the
identification of sites allocated to the lower income categories (very low and low):

• Zoning Appropriate to Accommodate Low and Very Low Income RHNA Allocation
o City must demonstrate that the zoning of a parcel allows for development at the default
density (differs based on a jurisdiction’s size and characteristics).
▪ The default density for the City of Newport Beach is 30 dwelling units per acre
(du/ac).
o The City can attempt justify the inclusion of parcels below the default density with
additional justification, such as experience developing affordable housing projects at
lower densities.
• Size of Sites
o Based on statewide affordable housing development history, HCD has established
sizing criteria for sites allocated to accommodate the lower income categories.
o The size of these parcels should be larger than 0.5 acres and less than 10 acres
▪ If parcels fall outside this range, additional justification must be provided, such
as successful development history on sites outside the size criteria.
• Affirmatively Furthering Fair Housing Requirements
o Pursuant to Gov. Code 65583(c)(10)(A), The City must evaluate future housing sites
in consideration of fair and equitable distribution of housing affordability throughout the
community.
• No-Net-Loss Law (SB166)
o Requires that at all times throughout the planning period, the sites inventory must
maintain adequate sites to meet the remaining unmet housing needs for each income
category.
o A jurisdiction is required to identify additional sites if it approves a project at different
income levels or densities than shown in the inventory.
o A buffer of housing capacity helps avoid no net loss implications.
SITES ANALYSIS BASELINE
The first step in the sites analysis process is to understand the portion of the RHNA Allocation that can
be accommodated by Accessory Dwelling Units (ADUs), by projects that are already in the planning
process (pipeline projects), and by sites that have existing capacity and propensity to redevelop within
the densities set by existing zoning code. These three categories establish the Sites Analysis Baseline
(the sites the City can list in the inventory without additional programs, policies, or rezones). By netting
out the Baseline from the RHNA Allocation, the City can understand the remaining units they must plan
to accommodate with redevelopment strategies.
Accessory Dwelling Units
The following is a summary of ADU features as they relate to the RHNA Allocation and Sites inventory:
• ADUs can be used to accommodate RHNA Growth need
• ADUs can be considered a supplementary method to accommodate future growth in
combination with other land use strategies
• New State Law allows ADU development as a matter of right in residential zones
• HCD has acceptable safe harbor methodologies to determine total ADU potential
• HCD has prepared a Guidebook, describing acceptable methodologies and approaches for
using ADUs to accommodate RHNA need

Safe Harbor Assumption: The City of Newport Beach can utilize HCD’s pre-certified methodology,
which permits the City to utilize past ADU production to calculate future ADU production. This Safe
Harbor assumption allows the City to utilize 2018-2020 past yearly production averages to
accommodate future housing needs.
Utilizing the Safe Harbor assumptions and the City’s 2018-2020 average annual production of 21.3
ADUs, ADU estimates by Income Category are show in the table below.
Safe Harbor Assumption of ADU Production
Income Category Percent Share of Estimated
ADU Production Total ADUs
Very Low 25% of total units 42 ADUs
Low 43% of total units 73 ADUs
Moderate 30% of total units 51 ADUs
Above Moderate 7% of total units 3 ADUs
TOTAL 170 ADUs
The City can the net out these ADU units from the total RHNA need for the 2021-2029 Planning Period
as shown in the table below.
ADU Production Assumption
Very Low Low Moderate Above Moderate
ADU Projections 42 73 51 3
Projects “in the Pipeline”
The City has housing projects in various stages of the entitlement process, including projects under
construction but not occupied, entitled projects and project in the pre-application of application process.
Collectively, these projects can be counted as credit to accommodate the 6th Cycle RHNA growth need,
provided they received a Certificate of Occupancy after June 30, 2021. The table below summarizes
these pipeline projects.
Summary of Projects in the Pipeline by Income Category
Very Low Low Moderate Above Moderate
Pipeline Projects 43 78 0 2,183
Based upon current projects in the pipeline, the City of Newport Beach has already met the 2021-2029
RHNA need for Above Moderate Income.

The final step in establishing the Baseline is to understand the City’s capacity within existing zoning.
The HEUAC recommended all sites included in the 5th Cycle Housing Element Update that have not
yet redeveloped be included in the 6th Cycle element as well (this does not include sites being
considered for rezones). These sites have already been determined to have propensity for
redevelopment because of the City’s comprehensive analysis effort as part of the 5th Cycle. The
capacity within the 5th Cycle Sites is outlined in the table below:
5th Cycle Housing Element Sites Used for the 6th Cycle
Very Low Low Moderate Above Moderate
5th Cycle Sites 0 0 348 40
Net Remaining Need for the 2021-2029 Planning Period
Combining the above considerations, the net remaining RHNA need can be calculated. As shown in
the table below, the net remaining need is 2,794 units for the 2021-2029 planning period. This net total
represents housing growth need that must be accommodated through the identification of adequate
sites.
Net Remaining 2021-2029 RHNA Need

FOCUS AREAS
General areas in the City to accommodate the net remaining RHNA are described below. Each of these
areas will contribute in some measure to the accommodation of future housing need.
Airport Area
The Airport Area has been a focus for development for the City for several years. The development of
higher-density residential units within this focus area will be critical to accommodating lower income
units. Increasing density within the Airport Area was also a key strategy as part of the City’s 4th and 5th
Cycle Housing Element Update.
West Newport Mesa Area
West Newport Mesa has been identified by the City as a major reinvestment and redevelopment
opportunity, where older industrial, smaller scale development can transition to support future
residential development. The adjacent Hoag hospital and supportive medical-related activities supports
the opportunity to provide housing opportunities for local workers of various income levels.
Dover-Westcliff Area
Dover-Westcliff has been identified as an area with opportunity to support increased density that is
compatible with adjacent higher density residential uses and other uses that will support residential
development.
Newport Center Area
Newport Center has recently had construction of several new residential developments. The City
expects the continuation of these development opportunities that creates housing adjacent to major
employment opportunities and support retail.
Coyote Canyon Area
Coyote Canyon is a closed landfill area with limited opportunities for active uses. A portion of the area
is not subject to these restrictions and is considered an ideal opportunity for future residential
development.
Banning Ranch Area
Banning Ranch has been utilized in prior planning periods to accommodate future housing need.
Banning Ranch was approved by the City but denied by the Coastal Commission in the past. The City
understands that future opportunities may still exist in the Banning Ranch area and would like to keep
the site under consideration for the 2021-2029 planning period.

RHNA ACCOMODATION SCENARIOS
To determine the location and strategies to accommodate future housing growth need, a series of
planning assumptions have been developed to determine the total net development capacity within
each of the focus areas previously evaluated by the Housing Element Advisory Committee. These
planning assumptions include:
Redevelopment Percentage
• What percentage, within the planning period (October 15th, 2021 – October 15th, 2029), of the
acreage is assumed to redevelop with residential units?
Affordability
• What is the assumed percentage of sites available to accommodate lower income housing
development?
Projected Average Density
• What is the assumed residential density of future housing development in each focus area?
Based on the variable assumptions above, the following two scenarios are presented for consideration:

Scenario #1 Minimum RHNA Accommodation
This scenario calculates the minimum inventory of parcels needed to meet the unaccommodated 2021-
2029 RHNA growth need. This scenario poses risks to the City resulting from no-net-loss provisions
requiring rezoning and other Housing Element compliance issues that may occur if sites are not
developed with the assumed affordability. The tables below provide a summary of this scenario:

Scenario #2 – Minimum RHNA Accommodation with Buffer
This scenario allows the City to accommodate the RHNA growth with a reasonable buffer to avoid no-
net-loss rezoning requirements and accommodates the reality that some sites will redevelop outside
the assumed affordability. A buffer between 15-30% is generally recommended by HCD. The scenario
summarized in the tables below includes the following considerations:
• A more aggressive approach to ADU production; and
• the addition of Banning Ranch as an opportunity area.
