NOW THEREFORE, the City Council of the City of Newport Beach resolves as follows: Section 1: Section I.A.6.e (Special Mooring Devices) of the Harbor Design Guidelines is amended to add a new paragraph (3) to read as follows, with all other provisions of the Harbor Design Guidelines to remain unchanged: Resolution No. 2022-9 Page 2 of 4 (3) Multiple Vessel Mooring System (MVMS) allows multiple vessels to be secured to a floating platform which is secured to a single anchor mooring system in Newport Harbor. This allows multiple vessels to side - tie to the floating platform therefore increasing vessel capacity at a mooring location. The intent of the MVMS is to provide increased small - boat storage at a mooring location within the single anchor mooring fields. (a) MVMS requests must be approved by the Harbor Department and Public Works Department prior to installation. Because of the potential conflict with adjacent moorings due to the increased mooring footprint, only single -hulled vessels will be permitted within the MVMS. (b) MVMS floats shall follow material and construction requirements as noted in these Harbor Design Criteria. The MVMS float width shall be 6 -feet. The MVMS float length shall be either 20 -feet or 40 -feet. The mooring tackle weight and chain specification for MVMS is maintained by the Harbor Department. The minimum specification for mooring tackle is calculated based on the maximum capacity (vessel size and number of vessels) for either the 20 -foot or 40 -foot MVMS, respectively. (c) The maximum vessel length overall (LOA) on each side of the MVMS shall be 22 feet. The maximum vessel overhang beyond the ends of the float shall be 3 feet. Vessels secured to the MVMS shall be side -tied in such a manner as to ensure the security of such vessels fore (bow) and aft (stern) at a minimum. (d) The maximum overall width of the MVMS system including the 6 - foot -wide float (i.e., boat + MVMS + boat) shall be 25 feet. (e) Coolers, benches, furniture, boat covers, trash, debris, or other items shall not be used or stored on the MVMS at any time. Up to 2 locker "dock" boxes may be permitted on the MVMS by the Harbor Department and shall follow material and installation requirements as set forth in these Harbor Design Criteria. No flammable, combustible or otherwise hazardous material shall be stored in the dock boxes or on the MVMS. A dock box shall be secured using reasonable commercial standards approved by the Harbor Department and shall only hold enough items so that the dock box cover remains fully closed at all times. Resolution No. 2022-9 Page 3 of 4 (f) The MVMS shall adhere to all provisions for harbor structures as stated in NBMC Title 17 including, but not limited to, "appropriate deterrent measures" to deter sea lions from boarding the MVMS. Section 2: The Harbor Design Guidelines, as amended, are attached hereto as Exhibit "A" and incorporated herein by reference. Section 3: The Public Works Design Standards are amended to add Standard Drawing No. 617 "Multiple Vessel Mooring System" which is attached hereto as Exhibit "B" and incorporated herein by reference. Section 4: The recitals provided in this resolution are true and correct and are incorporated into the operative portion of this resolution. Section 5: If any section, subsection, sentence, clause or phrase of this resolution is, for any reason, held to be invalid or unconstitutional, such decision shall not affect the validity or constitutionality of the remaining portions of this resolution. The City Council hereby declares that it would have passed this resolution and each section, subsection, sentence, clause or phrase hereof, irrespective of the fact that any one or more sections, subsections, sentences, clauses or phrases be declared invalid or unconstitutional. Section 6: The City Council finds the adoption of this resolution is not subject to the California Environmental Quality Act ("CEQA") pursuant to Section 15060(c)(2) (the activity will not result in a direct or reasonably foreseeable indirect physical change in the environment) and 15060(c)(3) (the activity is not a project as defined in Section 15378) of the CEQA Guidelines, California Code of Regulations, Title 14, Division 6, Chapter 3 because it has no potential for resulting in physical change to the environment, directly or indirectly. Resolution No. 2022-9 Page 4 of 4 Section 7: This resolution shall take effect immediately upon its adoption by the City Council, and the City Clerk shall certify the vote adopting the resolution.

Structural elements of the docks, floats, gangways, piles, etc., shall be adequate to safeguard human life, boats, and boating equipment. Boat berthing facilities shall be designed to adequately handle anticipated loads with reasonable factor of safety as deemed appropriate by the City of Newport Beach. Materials of construction shall resist corrosion from saltwater in order to assure low maintenance requirements and long life of the facility. Floats shall be designed to assure stability and buoyancy for safe operations. Adequate utilities meeting all requirements of the current, applicable codes shall be provided for the convenience and safety of boaters and maintenance workers. Harbor Permits and Plan Check shall be as per Title 17 of the City of Newport Beach Municipal Code and Council Policy H-1. Dock systems shall be designed by a civil or structural engineer, licensed by the State of California, who is experienced in the design of marine structures. Repairs and non-structural modifications to existing residential docks can be designed by a licensed contractor experienced in dock facilities, at the discretion of the City of Newport Beach. In accordance to California Building Code [A] 104.10 Modifications. "Wherever there are practical difficulties involved in carrying out the provisions of this code, the [Chief] Building Official shall have the authority to grant modifications for individual cases, upon application of the owner or owner's representative, provided the [Chief] Building Official shall first find that special individual reason makes the strict letter of this code impractical and the modification is in compliance with the intent and purpose of this code and that such modification does not lessen health, accessibility, life and fire safety, or structural requirements. The details of action granting modifications shall be recorded and entered in the files of the department of building safety." Fire Marshal approval shall be required for variances associated with the fire protection system. In accordance to California Building Code [A] 104.11 Alternative materials, design and methods of construction and equipment. "The provisions of this code are not intended to prevent the installation of any material or to prohibit any design or method of construction not specifically prescribed by this code, provided that any such alternative has been approved. An alternative material, design or method of construction shall be approved where the [Chief] Building Official finds that the proposed design is satisfactory and complies with the intent of the provisions of this code, and that the material, method or work offered is, for the purpose intended, at least the equivalent of that prescribed in this code in quality, strength, effectiveness, fire resistance, durability and safety." Fire Marshal approval shall be required for variances associated with the fire protection system. 7 I. WATERSIDE DEVELOPMENT The limits and constraints of construction in the harbor are defined by a series of lines that have been established over time by the Federal Government, as well as the City of Newport Beach. These lines have been defined in Chapter 17.01 of the Municipal Code. Prior to the preparation of documents to be submitted to the City of Newport Beach for review of a proposed project, the applicant should obtain a full understanding of these lines and have a qualified engineer, surveyor or contractor define these lines on any plans submitted for a proposed project. These lines include the existing or current edge of construction along the waterfront with respect to the Federal Bulkhead, Pierhead and Project Lines, Channel Lines, property lines (and their projections), Anchorage Area, and Turning Basins. A. DOCKS 1. ALTERNATIVE BERTHING GEOMETRIES Various berthing geometries are available and acceptable for the berthing of boats for a docking facility. The following layouts and designs present the generalized arrangements that are considered acceptable to the City of Newport Beach for the berthing of boats. The attached Figures and "Case" geometries can be utilized as shown, or in combination with one another, in an overall marina dock scheme. 2. LAYOUT AND DESIGN (Commercial & Residential) a. General (1) Layout and design of harbor facilities shall be based upon the use of the facility defined as follows: (a) Single or joint residential (b) Multi -residential (c) Commercial (Type 1): typical 1) Passenger (e.g., ferry, event cruise, etc. with no on - dock queuing) 2) Recreational boat marina 3) Yacht club 4) Other commercial (e.g., restaurant, office, yacht broker, etc.) 5) Public pier (d) Commercial (Type 2): not common in Newport Harbor 1) On -dock passenger staging (i.e., where passengers queue on the dock prior to boarding) 2) Docks used for transfer of cargo or other materials (2) Layout and Design Guidelines for Marina Berthing Facilities (2005 edition or as updated) published by the State of California State Parks Division of Boating and Waterways, except as modified by the City's Harbor Standard Drawings within the Design Criteria may be used as a guide to design harbor structures. (3) See the attached Harbor Standard Drawings for plans, sections and details of typical conditions for vessel moorings and docks, gangways, platforms, seawalls, and beach profiles. These Standards are to be considered minimum requirements for the cases represented and, at the City of Newport Beach discretion, may not apply to the specific project submitted. The City of Newport Beach reserves the right to mandate deviation from the Standards, if particular project conditions require special consideration. b. Slip and Boat Overhang into Adjacent Fairways (1) Berths shall not be occupied by vessels more than three (3) feet longer than the berth or slip, or in the case of fairways with a width of 1.75 x Lb (length of berth), not more than 10% of the length of the berth's finger. (2) For berths either parallel or perpendicular to a main channel, vessels can extend beyond the limits of the slip by as much as the beam of the boat. C. Finger and Walkway Widths (1) Minimum finger widths for recreational, commercial, and residential docks shall be per Table No. 1. (2) Fillets at the connection of walkways to fingers shall not have less than a 4 -foot side. (3) Outer end (end tie) and side -tie fingers shall be a minimum of one foot wider than the minimal widths for all other adjacent finger docks. (4) Residential Headwalks and Mainwalks IJ (a) Minimum residential headwalk widths shall be no less than six (6) feet for dock lengths up to 120 feet in total length, and eight (8) feet wide for dock lengths of more than 120 feet. (5) Commercial Headwalks and Mainwalks (a) Minimum widths shall be no less than six (6) feet for dock lengths up to 120 feet in total length, and eight (8) feet wide for dock lengths of more than 120 feet. If use of a walkway is for staging the public while waiting to board a vessel, the minimum dock width shall be 12 feet. (b) At gangways, a minimum of six (6) feet of walking surface shall be maintained in front of the farthest gangway projection (including toe plate) at high tide, and have a minimum of four (4) feet of clear space to walk along the side of any gangway for access to berthed vessels. Table No. 1 Minimum Finger Widths Finoer F float Width = 5.0' Lemyth of Berth All ADA Accessible Finger floats F = 3.0' Up to 35' F = 4.0' 36' to 59' F = 5.0' 60' to 79' F = 6.0' 0) 80' to 119' F = 8.0' 120' and over 0) Widths of more than that shown in this Table may be necessary for specific site conditions and/or uses of fingers over 70 feet. Minimum 5.0' widths are required for the entire path of travel for ADA access, including paths along main- and headwalks. See Section 5 of these Harbor Design Criteria for exceptions. Single and Double -Wide Slips (1) Single -wide slips are those slips that have a finger on each side of the boat. Double -wide slips have only one finger adjacent to any given boat. 10 e. Vessel "Rafting" (1) Vessel "rafting" is the practice of connecting multiple vessels together, with only one of the vessels being tied/berthed to a walkway or finger. Rafting of vessels is not allowed, unless specifically approved by the City's Harbor Department and/or the Fire Department for special facilities and/or events. Long Docks (1) Long docks are defined as side -tie docks with more than one boat berthed. Unless specifically identified otherwise, and for the purpose of establishing the number of boats that may utilize a long dock per DB W Layout and Design Guidelines for Marina Berthing Facilities (2005 edition or as updated), it will be assumed that one boat is berthed alongside a long dock every 40 feet of long dock length. This would relate to a 30 -ft berthed boat, with five (5) feet of clearance on either end. Distance between two adjacent boats shall be minimum 10 feet. g. Loading Criteria (1) The design of the dock system shall incorporate all anticipated dead and live loads. These criteria conform to DBW Layout and Design Guidelines for Marina Berthing Facilities (2005 edition or as updated). (a) Dead Loads: Dead loads shall include the weight of the dock system components (walers, bracing, bracket, etc.), which are permanently incorporated into the dock system, and non -dock system components (transformers, dock boxes, gangways, pumps, dinghy/kayak/SUP racks, trash containers, buildings, etc.) which are permanently affixed to the dock system. (b) Live Loads: Live loads are loads produced by the use of the dock system, such as people, carts, mobile equipment, etc. The dock system shall be capable of supporting live loads and freeboards per the "Flotation and Freeboards" section in these standards. The structure shall also be capable of supporting a 400 -pound moving point load anywhere on the deck surface, but no closer than 12" from any dock edge, while maintaining the level tolerances cited in this guideline. 11 (c) Wildlife Loads: Refer to DBW Layout and Design Guidelines for Marina Berthing Facilities (2005 edition or as updated) for live loads imposed by wildlife on the docks. These wildlife live loads may include sea lions. (2) Wind loads shall be calculated both parallel to and perpendicular to the maximum length of vessels and structures in accordance to current California Building Code. (a) Wind load on the lateral area of vessels or structures shall not be less than 15 pounds per square foot acting on the projected area of the docks as well as the profile area - "sail area" of the berthed vessels above water level. (b) Lateral area of vessels for wind load calculations acting on the "sail area" of the vessel shall be as per Exhibit No. 1, or the actual sail area of the anticipated vessel, whichever is greater. (c) Ten percent (10%) of the full wind load for an unshielded vessel shall be applied to each vessel in the leeward side of the unshielded vessel. (3) Current Loading: Floating docks in areas of the harbor may be subject to current loads. Dock shall be designed for minimum current velocity of 1 feet per second (1 feet/sec). (4) Impact Loading: Impact Load from design vessel (maximum boat size that may be moored on the dock) striking dock at 10 degree angle (from parallel to dock) with approach speed of minimum one feet per second (1 feet/sec). (5) Wave Loading: A simple wave analysis was conducted to provide general guidance of a 100 -year return period wind waves and ocean swells at Newport Harbor. In general, the majority of Newport Harbor is dominated by wind waves except for the areas near the harbor entrance which are dominated by ocean swells. Contact the City of Newport Beach, Public Works Department for details of reference study. A qualified civil engineer, licensed in the State of California, shall conduct site-specific engineering analysis to evaluate the appropriate design wave loading for the project. (6) Environmental Loads: Refer to DBW Layout and Design Guidelines for Marina Berthing Facilities (2005 edition or as 12 updated) for impact loads imposed by flooding, abandoned boats, broken docks, jetsam, tree limbs, or other debris. Environmental loads may occur throughout the Harbor but specifically in the Upper Bay and near the West Coast Highway bridge. (7) Load Combinations (a) Combined load cases for design of docks shall include the following: 1) Dead load plus uniform live load. 2) Dead load plus concentrated 400-1b live load. 3) Dead load plus wind load plus current & wave loads. 4) Dead load plus impact load. (b) Fabrication, handling, and lifting loads shall also be checked in the calculation of the dock system. (c) For design of wood structures, the load duration factors in Table 2.3.2 of the latest edition of the American Wood Council National Design Specifications (NDS) may be applied. Allowable Stress Design and Load and Resistance Factor Design values for wood members shall be reduced by the Wet Service Factor according to Tables 4.3.1, 5.3.1 and 8.3.1 of the NDS. (d) Calculations shall include the transfer of forces from the dock system into the piles. All components within this transfer mechanism shall be substantiated. (e) Load combinations for vertical load bearing structural elements (i.e., piers, wharves, and platforms) in Section 1605 of the California Building Code (2019 or latest edition) and Section 5.3 of the Building Code Requirements for Structural Concrete (ACI 318-19 or latest edition) respectively, shall apply. 13 Exhibit No. 1 Wind Load Vessel profile heights for "sail area" (Recreational & Commercial Vessels) 35 34 - 33 - 32 000, OF 31 _ 30 - 29 — 28 27 26 00, 25 } 24 v a' 23 1- 22 Of 21 ••_' Q� a� 20 1•'� v 19 — -- `~O 18 Q 17 _ v 0 16- Q) 15 _ ,,.. _ ., _ .... -- — Q 14 _ N ul 13 a� > 12 11 10 { 8 _ _---- _ 6 ' 5 — 4 20 30 40 50 60 70 80 90 100 110 120 130 140 150 160 170 '80 190 200 210 220 Vessel length overall, in feet ;ft.) 14 h. Flotation and Freeboards (1) Sufficient flotation shall be provided to support dead load plus live load with freeboards as noted below. Higher live load requirements may be required by the City of Newport Beach, under special circumstances as may be deemed appropriate. Dock freeboard shall be minimum 14 inches and maximum 24 inches, under dead load. Dock freeboard shall not be less than nine (9) inches and there shall be minimum one (1) inch of pontoon freeboard remaining, under dead plus live load. See Figure No. 13 for typical concrete dock system (where dock system itself is the pontoon) and Figure No. 14 for typical timber, aluminum, steel, and composite framing dock system (where framing is supported by pontoons). (a) Residential docks, including multi -family residential, shall be designed for a live load of 25 pounds per square foot. (b) Marinas, Public Pier (also known as Public Docks) and Commercial Docks (Type 1 docks subject to high volumes of pedestrian traffic such as docks used for ferries, charter boats, fishing boats, boat shows, shuttles, water taxis, etc.) shall be designed for a live load of 40 pounds per square foot. Type 1 commercial docks are typical in Newport Harbor. Commercial Docks (Type 2), as previously described, which are also used for the on -dock staging (queuing) of passengers, or are subject to high volumes of cargo or other materials, shall be designed for live load of 65 pounds per square foot. Signage indicating maximum number of people (using occupant load factor 200 pounds/person) that may be staged (Dock Staging Capacity) shall be posted at a prominent location at staging area. Type 2 commercial docks are not common in Newport Harbor. Exception 1: Docks whose functionality requires dead load freeboard less than 14 inches (docks used for kayaks, rowboat, etc.) shall be designed for 25 pounds per square foot live load. These special docks shall be exempt from the freeboard requirement on "Floatation and Freeboard" in Section U. Signage indicating maximum number of people (using occupant load factor = 200 pounds/person) that may use the dock (Dock Capacity) shall be posted at a prominent location. 15 Exception 2: Repair or modification to less than 50% of an existing dock is exempt from the freeboard requirement on "Floatation and Freeboard" in Section h.1. However, Engineer of Record shall perform freeboard calculation, to provide sufficient floatation under repaired or modified portion of dock section, to match freeboard of existing dock and support minimum live load of 25 pounds per square foot. (c) Weight of seawater, for the purposes of flotation calculations, shall be 64 pounds per cubic foot. (2) The flotation shall use a rigid block of expanded polystyrene (EPS) cores or equivalent. The use of hollow pontoons shall not be allowed. (3) Docks shall have pontoons composed of outer shells of either concrete (1" minimum thickness) or an ultra -violet stable plastic such as fiberglass or cross-linked polyethylene (1/8" minimum thickness). Other alternative materials must be submitted to the City for review and approval, per the "Request for Alternate Material or Method of Construction" appeals process. Exposed foam flotation is not allowed. (4) Residential Docks: In addition to the pontoon encapsulation types noted above, residential docks may also use spray -on elastomeric encapsulation systems for pontoons. Spray -on products must demonstrate resistance to ultra -violet rays, solvents that may be present on the water surface, and environmental conditions imposed by saltwater contact. Minimum spray -on product thickness shall be 100 mils. Static Floating Tolerances (1) The dock surface of the in-place dock system, which includes finger floats and walkways, under various loading conditions, shall be level within the following tolerances: Under Dead Load Only, & Under Dead and Live Loads: 0 1/4" per foot, 1" maximum (transverse) 0 1/8" per foot, 1" in 10 feet maximum (longitudinal) Under Dead and Point Live Loads: 0 1/2" per foot (4%), 2" maximum (transverse) 0 1/4" per foot, 2" in 10 feet maximum (longitudinal) 16 On Accessible Routes, for ALL Loading Conditions: o Shall not exceed 1:50 or 2% maximum (transverse) (2) Under Dead Load Only conditions, the free ends of finger floats shall always float level or higher than the finger float ends connected to the head or mainwalk, within the limits noted above. j. Torsional Resistance Requirements (1) General: Fingers, connected walkways, and free-standing headwalks unattached to other dock elements must be designed to provide dock stability and resistance to torsional loads. Torsion bars installed in fingers, and/or dock framing construction that provides for calculated and verifiable twist resistance, is required. Free-standing headwalks need not provide independent means of torsional resistance if the width of headwalk is eight (8) feet or more. Alternative means of providing torsional resistance to fingers and main- or headwalks may be considered by the City of Newport Beach. Methods such as twist -controlling guide roller assemblies may be considered, if acceptable twist resistance can be proved. k. Guide Piles (1) Dock system pilings shall be designed by a licensed Civil or Structural Engineer, registered in the State of California, who shall have demonstrated expertise in the design of marine structures. Pile loading calculations shall be provided based on a soils investigation by a licensed Geotechnical Engineer, registered in the State of California, or based on minimum code values for soil properties. (a) Alternatively, a static pile load test may be conducted by a professional geotechnical or structural engineer licensed in the state of California and qualified third -party testing agency after piles have been driven, to confirm that the piles can withstand the design loads anticipated. Testing procedures shall be in general conformance with testing procedures defined in Chapter 8 of the Caltrans Foundation Manual (2015 or latest edition) and must be approved by the City prior to commencement. Static pile load tests shall be designed for the type of load to be experience by the pile (lateral loads for guide piles and vertical/uplift loads for 17 platform/pier piles) and for the estimated loads based on berthed vessel sizes and dead and live loads. (2) Soil conditions in Newport Harbor can vary depending on the existence of rock strata near historic bluffs along the coastline.

Special Mooring Devices (1) Special vessel mooring devices may be required or desired for specific berthing conditions. Large vessels may require mooring and/or breasting dolphins (pile groupings designed to resist large impact and berthing loads), berthing walls, or other devices that facilitate vessel docking. (2) Special mooring devices shall be designed by a California -licensed Civil or Structural Engineer with input provided by California - licensed Geotechnical Engineer, all with experience in waterfront engineering. Special mooring devices shall be designed to resist berthing loads, wind, wave, and current loading for the localized area. (3) Multiple Vessel Mooring System (MVMS) allows multiple vessels to be secured to a floating platform which is secured to a single anchor mooring system in Newport Harbor. This allows multiple vessels to side -tie to the floating platform therefore increasing vessel capacity at a mooring location. The intent of the MVMS is to provide increased small -boat storage at a mooring location within the single anchor mooring fields. (a) MVMS requests must be approved by the Harbor Department and Public Works Department prior to installation. Because of the potential conflict with adjacent moorings due to the increased mooring footprint, only single -hulled vessels will be permitted to use the MVMS. (b) MVMS floats shall follow material and construction requirements as noted in the Harbor Design Criteria. The 33 MVMS float width shall be 6 -feet. The MVMS float length shall be either 20 -feet or 40 -feet. The mooring tackle weight and chain specification for MVMS is maintained by the Harbor Department. The minimum specification for mooring tackle is calculated based on the maximum capacity (vessel size and number of vessels) for either the 20 -foot or 40 -foot MVMS, respectively. (c) The maximum vessel length overall (LOA) on each side of the MVMS shall be 22 -feet. The maximum vessel overhang beyond the ends of the float shall be 3 -feet. Vessels secured to the MVMS shall be side -tied in such a manner as to assure the security of such vessels fore (bow) and aft (stern) at a minimum. (d) The maximum overall width of the MVMS system including the 6 -foot -wide float (i.e., boat + MVMS + boat) shall be 25 -feet. (e) Coolers, benches, furniture, boat covers, trash, debris, etc. shall not be used or stored on the MVMS at any time. Up to two (2) locker "dock" boxes may be permitted on the MVMS by the Harbor Department and shall follow material and installation requirements as noted in the Harbor Design Criteria. No flammable, combustible or otherwise hazardous material shall be stored in the dock boxes or on the MVMS. A dock box shall be secured using reasonable commercial standards approved by the Harbor Department and shall only hold enough items so that the dock box cover remains fully closed at all times. (f) The MVMS shall adhere to all provisions for harbor structures as stated in NBMC Title 17 including, but not limited to, maintaining appropriate measures to deter sea lions from boarding the MVMS. f. Piers, Platforms, and Wharves (1) Piers, platforms, and wharves shall be designed by a California - licensed Civil or Structural Engineer experienced in waterfront structures. A geotechnical report, for pile design and installation, shall be provided that addresses special issues such as liquefaction potential, and the vertical (gravity) and seismic support of the waterfront structure. The geotechnical report shall be prepared by a California -licensed Geotechnical Engineer. 34 (2) Refer to the Harbor Standard Drawings for the various geometries allowed for piers and platforms that serve and provide access to residential floating docks. (3) Commercial: Structures shall be designed for an assembly area live load of 100 pounds per square foot (psf). If vehicles shall be used on the structure for maintenance purposes, then vehicle loads shall be used for the design of the structure. If vehicle loads exceed 100 psf, then vehicle loads shall govern. (4) Residential: Structures shall be designed for a minimum live load of 50 psf. g. Seawalls (Bulkheads) (1) General: Several types of seawalls are common to support soils and construction on the landside of the wall. Seawall material can be composed of various types of materials, including concrete, steel, and other manufactured materials. Typical wall types include freestanding or "cantilevered" seawalls and "tied -back" seawalls. Cantilevered seawalls are limited by the height of the wall above the waterside mudline and are generally effective for exposed heights of not more than 8 feet. For structural steel type seawalls, higher exposed heights are possible. Tied -back seawalls can be effective for exposed heights over 8 feet and may require continuous caps, walers (beams), steel tie rods and a foundation anchors (deadman), or earth anchors. Tie -back anchor systems shall require protection against corrosion. Galvanic anode cathodic protection system is recommended. Tie -back anchor system shall be designed to last the life of seawall. (2) Generally, seawall sheets constructed of reinforced, prestressed concrete are desirable, although for special conditions, structural steel interlocking sheets may be necessary. Steel products in the marine environment require special non-toxic coating protection and cathodic protection, in order to provide extended life spans. (3) The City understands there is a threat of flooding and inundation in and around Newport Harbor due to sea level rise. Newport Harbor and adjacent low-lying areas rely on a system of harbor bulkheads, seawalls, revetments, or other improvements to function. Additionally, the system of shoreline defenses protects existing development, public access, public views, and scenic qualities of the coastal zone. The City is committed to using the best available science to determine a range of sea level rise projections for use in developing harbor development standards 35 and in reviewing Coastal Development Permit applications. Currently the best available science is the State of California Sea Level Rise Guidance, 2018 Update. Experts acknowledge that there is considerable uncertainty in the magnitude and rate of the rise in sea level and as a result, the City recognizes the need to set standards over time that provide protection from future sea level rise given the inherent uncertainty of the rate and magnitude of the rise. Bulkheads, seawalls or other protective improvements shall be constructed and maintained as shown in Table No. 2. The structure shall also be initially designed and constructed to accommodate and receive future increases in height when directed by the City to protect adjacent low-lying areas from future flooding without the need to replace or substantially alter the structure. Table No. 2 Year Structure Permitted Adopted NB Standard Elevation feet ' Design for Adaptability Elevation (feet)2 NAVD88 MLLW NAVD88 MLLW 2020 10.7 10.9 13.7 13.9 2021-2025 10.9 11.1 14.4 14.6 2026-2030 11.0 11.1 14.6 14.8 2031-2035 11.0 11.2 14.8 15.0 1. Derived using the Upper Limit of the Low Risk Aversion probabilistic sea level rise protection scenario for the Los Angeles tidal gauge, estimated 75 years into the future based on the State of California Sea Level Rise Guidance, 2018 Update. This scenario accounts for the upper range of what is "likely to occur" with approximately an 83 percent probability that sea level rise falls below the elevations shown. 2. Derived using the Medium -High Risk Aversion probabilistic sea level rise protection scenario for the Los Angeles tidal gauge, estimated 75 years into the future based on the State of California Sea Level Rise Guidance, 2018 Update. This scenario accounts for increased sea level with approximately a I -in -200 or 0.5 percent probability that sea level rise exceeds the elevations shown. (4) The distance between seawalls and all floating dock components shall be a minimum of one foot horizontal distance. (5) Seawalls shall be designed to resist all applicable vertical and horizontal loads. (6) A minimum safety factor of 1.5 shall apply to gravity loads, and a minimum safety factor of 1.1 shall apply to seismic loading cases for the stability of seawalls. (7) Decking may butt to the seawall cap, or cantilever over the top of the seawall, if approved. (8) Wing Walls: Wing walls are retaining walls that project landward and are perpendicular to the seawall. Wing walls may be necessary to isolate the seawall protection system of one property to the adjacent property. Special care must be taken to assure that the construction of a seawall for the subject property does not adversely impact the seawalls of the adjoining properties, either during construction or over the life of the structures. (9) Seawall design requires a soils report from a California -licensed Geotechnical Engineer experienced with the design of waterfront structures. Any sloping surface on the water or landside of the seawall must be accounted for in the calculations for the seawall. (10) All concrete sheets used for seawall construction shall be designed as pre -cast, pre -stressed concrete elements.
