RESOLUTION NO. ZA2020-016
A RESOLUTION OF THE ZONING ADMINISTRATOR OF THE
CITY OF NEWPORT BEACH APPROVING COASTAL
DEVELOPMENT PERMIT NO. CD2019-047 TO DEMOLISH AN
EXISTING SINGLE-FAMILY RESIDENCE AND CONSTRUCT A
NEW SINGLE-FAMILY RESIDENCE WITH A THREE -CAR
GARAGE AND ACCESSORY STRUCTURES LOCATED AT 1140
WEST BAY AVENUE (PA2019-174)
THE ZONING ADMINISTRATOR OF THE CITY OF NEWPORT BEACH HEREBY FINDS AS
FOLLOWS:
SECTION 1. STATEMENT OF FACTS.
An application was filed by Bradford C. Smith, Architect (Applicant), with respect to
property located at 1140 West Bay Avenue, requesting approval of a coastal development
permit.
The lot at 1140 West Bay Avenue is legally described as Lot 1, Block 4 of Tract 626.
The Applicant proposes a coastal development permit (CDP) to allow the demolition of an
existing single-family residence and the construction of a new three-story, 4,052-square-
foot, single-family residence, including an attached 740-square-foot, three -car garage. The
proposed development also includes additional appurtenances such as walls, fences,
patios, hardscape, drainage devices, and landscaping. No work will be conducted bayward
of the existing bulkhead. The design complies with all applicable development standards
and no deviations are requested.
4. The subject property is designated Single -Unit Residential Detached (RS-D) by the
General Plan Land Use Element and is located within the Single -Unit Residential (R-1)
Zoning District.
5. The subject property is located within the coastal zone. The Coastal Land Use Plan
category is Single -Unit Residential Detached (RSD-C) (10.0 — 19.9 DU/AC) and it is
located within the Single -Unit Residential (R-1) Coastal Zone District.
6. A public hearing was held on February 13, 2020, in the Corona del Mar Conference Room
(Bay E-1st Floor) at 100 Civic Center Drive, Newport Beach. A notice of time, place and
purpose of the hearing was given in accordance with the Newport Beach Municipal
Code. Evidence, both written and oral, was presented to, and considered by, the Zoning
Administrator at this hearing.
SECTION 2. CALIFORNIA ENVIRONMENTAL QUALITY ACT DETERMINATION.
1. This project is categorically exempt pursuant to Title 14 of the California Code of
Regulations Section 15303, Article 19 of Chapter 3, Guidelines for Implementation of
the California Environmental Quality Act (CEQA) under Class 3 (New Construction or
05-15-2018
Zoning Administrator Resolution No. ZA2020-016
Paqe 2 of 9
Conversion of Small Structures), because it has no potential to have a significant effect
on the environment.
Class 3 exempts the demolition of up to three single-family residences and additions of
up to 10,000 square feet to existing structures. The proposed project consists of the
demolition of one single-family residence and the construction of a new 4,052-square-
foot, single-family residence with an attached 740-square-foot, three -car garage. The
proposed project is a new single-family residence located in the R-1 Coastal Zoning
District.
3. The exceptions to this categorical exemption under Section 15300.2 are not applicable.
The project location does not impact an environmental resource of hazardous or critical
concern, does not result in cumulative impacts, does not have a significant effect on the
environment due to unusual circumstances, does not damage scenic resources within
a state scenic highway, is not a hazardous waste site, and is not identified as a historical
resource.
SECTION 3. REQUIRED FINDINGS.
In accordance with Newport Beach Municipal Code (NBMC) Section 21.52.015 (Coastal
Development Permits, Findings and Decision), the following findings and facts in support of
such findings are set forth:
Finding:
A. Conforms to all applicable sections of the certified Local Coastal Program.
Facts in Support of Finding:
The proposed development complies with applicable residential development standards
including, but not limited to, floor area limitation, setbacks, height, and parking.
a. The maximum floor area limitation is 5,489 square feet and the proposed floor area
is 4,792 square feet.
b. The proposed development provides or exceeds the minimum required setbacks,
which are 25 feet along the front property line abutting Newport Bay, 4 feet along
each side property line, and 5 feet along the second frontage abutting West Bay
Avenue.
c. The highest guardrail is 24 feet from established grade (9.53 feet based on the
North American Vertical Datum of 1988 [NAVD88]) and the highest ridge is no more
than 29 feet from established grade, which comply with the maximum height
requirements.
The project includes garage parking for a total of three vehicles, complying with the
minimum three -car garage parking requirement for single-family residences with
more than 4,000 square feet of living area.

Zoning Administrator Resolution No. ZA2020-016
Paae 3 of 9
2. The neighborhood is primarily developed with two-story, single-family residences and,
particularly on the opposite side of West Bay Avenue, multi -family structures. Newer
residential developments in the neighborhood are three stories and the proposed
design, bulk, and scale of the development is consistent with the existing neighborhood
pattern of development and expected future development consistent with applicable
development standards.
3. Located on the northern extent of the Newport Peninsula, between 12th Street and 11 th
Street, the site is a private bay front parcel. An existing seawall centrally protects the
site with the top of the bulkhead at an approximate elevation of 9.5 feet based on the
North American Vertical Datum of 1988 (NAVD88). The on -site privacy wall located
along the 12th Street side is a secondary shoreline protective device. As described in
the project's bulkhead condition report, visual inspection of the bay front seawall
revealed that the structure appears to be in good condition and is not in need of
maintenance. However, existing structures and improvements prevent a precise
determination of its adequacy if it is found necessary to add protection up to the required
elevation of 10.60 feet (NAVD88). The side -facing shoreline protection wall should be
replaced if needed. The report recommends a structural assessment of both the bay
and side property walls after removal of the site's rear patio. If the bay wall proves
adequate, then the elevation of the top of the shore protection will be capped to the
minimum elevation of 10.6 feet (NAVD88). Alternatively, if it is determined the bay front
wall requires replacement, a new bulkhead will be constructed to the minimum elevation
of 10.6 feet (NAVD88).
4. GeoSoils, Inc. prepared the project's Coastal Hazards and Bulkhead Condition Report,
dated October 29, 2019. As described above, this report directs additional investigation
of the existing seawall's structure to help determine whether a cap or an entirely new
seawall will be required up to the minimum 10.6-foot (NAVD88) elevation. Newport Bay's
historical design flood elevation is 7.7 feet (NAVD88). In employing the high estimate of
the "low risk aversion" scenario for sea level rise from the California Ocean Protection
Council, the projection is a 2.9-foot increase in sea level rise (or overall elevation of 10.6
feet [NAVD881) for the next 75 years. Waves resulting from wakes and winds pose the
possibility to reach the shore protection fronting the site. The site has not been subject
to flooding, erosion damage, or wave runup attack in the past. Based on the calculated
wave run up under the current 100-year recurrence interval conditions, future sea level
rise of more than 2 feet could enable boat wakes during high tides to overtop the
bulkhead. For this reason, after the patio demolition, the report advises an analysis of
the existing wall to achieve an added wall height of 12.5 feet (NAVD88), in keeping with
the adaptation strategy from the CCC Sea Level Rise Policy Guidance (2018).
Ultimately, the GeoSoils, Inc. study recognizes that the new or modified bulkhead with
the minimum 10.6-foot (NAVD88) elevation and the maintenance of the 12th Street
privacy wall would protect the proposed development from any existing or anticipated
future coastal hazards for the next 75 years or more. During this 75-year period, no
additional shoreline protective devices will be necessary to protect the proposed
development.

5. Pursuant to Newport Beach Municipal Code (NBMC) Subsection 21.30.030(C)(3)(i)(iv),
the property owner will be required to enter into an agreement with the City waiving any
potential right to protection to address situations in the future in which the development is
threatened with damage or destruction by coastal hazards such as waves, erosion, and
sea level rise. The property owner will also be required to acknowledge any hazards
present at the site and unconditionally waive any claim to damage or liability against the
decision authority, consistent with NBMC Subsection 21.30.015(D)(3)(c).
6. The property is located in an area known for the potential of seismic activity and
liquefaction. All projects are required to comply with the California Building Code (CBC)
and Building Division standards and policies. Geotechnical investigations specifically
addressing liquefaction are required to be reviewed and approved prior to the issuance of
building permits. Permit issuance is also contingent on the inclusion of design mitigation
identified in the investigations. Construction plans are reviewed for compliance with
approved investigations and CBC prior to building permit issuance.
1. The property is located adjacent to coastal waters. Pursuant to NBMC Section 21.35.050
(Water Quality and Hydrology Plan), due to the proximity of the development to the
shoreline and the development containing more than 75 percent of impervious surface
area, a Water Quality and Hydrology Plan (WQHP) is required. The WQHP would include
a polluted runoff and hydrologic site characterization, a sizing standard for Best
Management Practices (BMPs), use of an LID (Low Impact Development) approach to
retain the design storm runoff volume on site, and documentation of the expected
effectiveness of the proposed BMPs.
7. Proposed landscaping complies with NBMC Section 21.30.075 (Landscaping) by
incorporating drought -tolerant, non-invasive plant species and a water efficient irrigation
design. Condition of Approval No. 22 requires the approval of a final landscape plan
prior to the issuance of a building permit.
Finding:
B. Conforms with the public access and public recreation policies of Chapter 3 of the
Coastal Act if the project is located between the nearest public road and the sea or
shoreline of any body of water located within the coastal zone.
Facts in Support of Finding:
1. The project site is located between the nearest public road and the sea or shoreline, but
the project will not affect the public's ability to gain access to, use, and/or view the coast
and nearby recreational facilities. The nearest coastal access opportunity is currently
provided at the north ends of 12th and 11th Street: the first directly abuts the subject site
and the latter lies approximately 360 feet westward of the subject site.
2. Vertical access to the public beach is available along the south street ends of 12th Street
and 11 th Street, between 580 and 700 feet away from the project site. The public beach to
the south also includes a 12-foot-wide public sidewalk along West Ocean Front, providing
lateral access and views of the beach. The proposed replacement of the existing single-
05-15-2018
Zoning Administrator Resolution No. ZA2020-016
Paae 5 of 9
family residence with a new single-family residence does not include any features that
would provide or inhibit coastal public access opportunities.
3. The 12th Street public right-of-way will remain free and clear of any obstructions during
construction and new or existing improvements (including landscaping and construction
activities) are not authorized on State tidelands, public beaches, or the public right-of-way.
4. The property is not located near designated public viewpoints or coastal view roads. The
nearest public viewpoint is located at the City's Marina Park Community and Sailing
Center, approximately 1,500 feet westward of the property. Due to the distance of the
proposed development from the public viewpoints and the project's compliance with
height and setbacks, the project will not impact coastal views. The proposed single-family
residence complies with all applicable development standards and maintains front setback
areas consistent with the existing neighborhood pattern of development. The project does
not contain any unique features that could degrade the visual quality of the coastal zone.
SECTION 4. DECISION.
NOW, THEREFORE, BE IT RESOLVED:
1. The Zoning Administrator of the City of Newport Beach hereby finds this project is
categorically exempt from the California Environmental Quality Act pursuant to Section
15303 under Class 3 (New Construction or Conversion of Small Structures) of the CEQA
Guidelines, California Code of Regulations, Title 14, Division 6, Chapter 3, because it has
no potential to have a significant effect on the environment.
2. The Zoning Administrator of the City of Newport Beach hereby approves Coastal
Development Permit No. CD2019-047, subject to the conditions set forth in Exhibit "A,"
which is attached hereto and incorporated by reference.
3. This action shall become final and effective 14 days following the date this Resolution
was adopted unless within such time an appeal or call for review is filed with the
Community Development Director in accordance with the provisions of NBMC Title 21
Local Coastal Implementation Plan. Final action taken by the City may be appealed to
the Coastal Commission in compliance with NBMC Section 21.64.035 of the City's
certified LCP and Title 14 California Code of Regulations, Sections 13111 through
13120, and Section 30603 of the Coastal Act.

nesting season from February 1 to August 15, compliance with the following is required
to prevent the taking of Native Birds pursuant to MBTA:
A. The construction area shall be inspected for active nests. If birds are observed flying
from a nest or sitting on a nest, it can be assumed that the nest is active. Construction
activity within 300 feet of an active nest shall be delayed until the nest is no longer
active. Continue to observe the nest until the chicks have left the nest and activity is no
longer observed. When the nest is no longer active, construction activity can continue
in the nest area.
B. It is a violation of state and federal law to kill or harm a native bird. To ensure
compliance, consider hiring a biologist to assist with the survey for nesting birds, and
to determine when it is safe to commence construction activities. If an active nest is
found, one or two short follow-up surveys will be necessary to check on the nest and
determine when the nest is no longer active.
