CASHIER RECEIPT NUMBER:l'[�f��F�xa C� Fonns{regmodif 01126/12 Guidelines for Approval of Alternate Materials, Design and Methods of Construction Basis For Approval For the Building Official and Fire Marshal or their designated agent to approve a request for modification or a request for alternate material or method of construction, he/she must determine that special, individual reasons exist that make compliance with the strict letter of the Code impractical and that equivalency is provided. The resulting condition must be in conformance with the spirit and purpose of the Code provisions involved and that such modification does not lessen fire protection, structural integrity or occupant safety. The applicant must provide sufficient information with this application to allow the above evaluation to be made. Reguirements for Submittals ^ The applicant design professional shall prepare a Written Report that describes the alternate proposal along with the applicable data listed below-, • State specific code provisions for which altemative is requested and why request is being submitted. • Describe by code section those provisions for which alternative is desired. • Compare the proposed alternative versus the code requirements in terms of structural strength, suitability, effectiveness, fire resistance, safety.and health impacts affecting the building or user of the building. • Demonstrate that the proposed altemative is compatible with balance of code requirements. • When applicable, specify how authoritative consensus document(s) are used to substantiate proposal. (Reference draft ICC Building Performance Code Commentary Section 1.4.2:3 for background information). • Provide assumptions, references, and documentation of evaluation methods utilized. This includes intended use, input data, anticipated outputs, and limitations of computer models and other analytical tools or methods. • Specify when and where special inspection and testing are required and the standards of acceptance for demonstrating compliance. Show how the proposed alternate, if accepted, will be identified on the job site. • Where land use restrictions and building setbacks are required, deed restrictions may be an appropriate method to ensure continued compliance. • State how and where alternate proposal is incorporated within construction plans and prepare plan amendments as necessary. The design professional has the responsibility to coordinate all construction documents and ensure compatibility between documents. • The report and design documents shall be dated, signed and stamped by the design professional according to the plan submittal procedure. • For alternate methods of design requests, the applicant shall set performance criteria for his design. Performance criteria shall be reviewed, amended and approved by the Building Official prior to start of design. Alternative Desian ReviewNerifieation The Building Official has the responsibility to review design submittals for compliance to'the adopted codes and procedures. if the Building Official does not have the expertise on staff -to make a thorough and competent review, the Building Official shall select a consultant that possesses the necessary qualifications to perform a third -party or peer review. Cost of peer review shall be paid by applicant to the Building Department prior to commencing the review. • Verify that all applicable information and justifications listed above as requirements for submittals is received and verify that evaluation and design methods used by designer are appropriate to the alternative proposed. • Verify products ' are being used in accordance with their listing conditions as required by recognized listing agencies. If not available, require documentation and/or testing to demonstrate compliance with intent of code and intended use. • Evaluate performance of material and possible flaws that could affect performance of material in its installed state. • The reviewer shall document that the submittal has been reviewed and accepted as meeting the alternative materials, design, and methods of construction provisions of the code_ If the Building Official is not satisfied that the applicant has met the conditions, the request should be denied in writing with the applicable reason(s). Inspection/Field Verification The alternate proposal as approved in the construction documents must be verified by inspection, and, where .necessary, testing as follows: • To verify that alternate materials, systems and fabricated products comply with accepted design criteria and the manufacturer's and engineers installation procedures, inspectors should check product labeling, certification, quality assurance processes, and testing, as applicable. • When appropriate, an approved third party quality assurance inspection and testing service may be required for continuous and complex inspection and testing activities. This is intended to verify that construction complies With the code and the approved plans. Appeal from the determination or action of the Building Official or Fire Marshal or their designated agent may be made to the Building Board of Appeals. To appeal, the applicant must provide special individual reasons that make compliance with the strict letter of the Code impractical. Appeals or ratifications pertaining -to State Disabled Access Standards require complete evidence to substantiate that the proposed design is equivalent to that prescribed by that standards or that due to legal or physical constraints, compliance with the standards or providing equivalency would create an unreasonable hardship. Appeals must be submitted on the Appeal Form available at Permit Counter accompanied by the, proper fee. You will be notified in writing of the appeal hearing's time and date. ATTACHMENT 1 3. JUSTIFICATION /FINDINGS OF EQUIVALENCY: 1. The City of Newport Beach — Harbor Design Criteria — Section 2.h.1.a (On page 11)(See Attachment 1) specifies 50 psf live load for commercial Dock, Dead Load (DL)+ Live Load (LL) freeboard of 15". Also DL min freeboard is 18" and DL max freeboard is 24" The density of water is 64 Ibs/ft3. If you design for max 24" DL freeboard and 75% floatation (25% is for holes on dock for pile anchor system and pontoons are not completely rectangular and allow water flow (circulation) to prevent debris collection). When 50 psf live load is applied to the dock, the dock will sink by 50/(0.75x64)x12" = 12.5". Hence DL+LL freeboard would be 24"-12.5"=11.5". However the Min DL+LL freeboard required per City of Newport Beach — Harbor Design Criteria is 15". Hence it is NOT possible to achieve 50 psf live load AND DL+LL freeboard of 15". "Layout and Design Guideline for Marina Berthing Facilities" —July 2005 by California Dept of Boating and Waterways (See Attachment 2) (Referred in The City of Newport Beach — Harbor Design Criteria — Section 2.a.2 page 5)(See Attachment 1) recommends 25 psf live load and DL+ LL Freeboard of 10". Proposed dock system allowable live load capacity is 35psf. We propose to post a sign at the entrance of the Dock showing Max Dock Occupancy. Occupancy will be based on 200 lb/person. Newport Harbor Yacht Club Marina is used for recreational boats (Max boat size 42'). Design DL Freeboard of 22" is desired for these boats. General Calculation for DL+ 35 psf LL Freeboard is 22"-35/(0.75x64)x12"=13.25" Hence Min DL+LL Freeboard requested is 13" instead of 15". The dock structure is 11.25" tall (lY2" Deck+ 9" Waler+%" Plywood Diaphragm). Pontoon under the structure provides floatation. At DL+ LL (35 psf) the pontoon shall have at least 2" (13"-11.25") of freeboard remaining (Reserve Buoyancy). s This is phase two of approved plan check 1855-2012. See attached Request for Modification to provisions of title 15 of the Newport Beach Municipal Code. Case No. 2012-46. Approved Nov. 14 2012. CITY OF NEWPORT BEACH WATERFRONT PROJECT GUIDELINES 0 1 SIL41 VWX 0111'' i HARBOR DESIGN CRITERIA COMMERCIAL & RESIDENTIAL FACILITIES r E 1 \`/ FQ Rr/ 2008 EDITION utilized as shown, or in combination with one another, in an overall marina dock scheme. 2. LAYOUT AND DESIGN (Commercial & Residential) a. General G7 � I�tio F I�I L6 (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 1) Passenger 2) Recreational boat marina (2) (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 Building Department discretion, may not apply to the specific project submitted. The Building Department reserves the right to mandate deviation from the Standards, if particular project conditions require special consideration. Slip and Boat Overhang into Adjacent Fad (1) Berths shall not be occupied by vessels more than 3 feet longer than the berth or slip, or in the case of fairways with a 1.75 x Lb width, not more than 10% of the length of the 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. 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 by the Building Department. (a) Exception: For alterations to existing docks, match the original design loads and freeboards. (b) Residential Docks: Live load of 25 pounds per square foot with a dead plus live load freeboard of not less than 10 inches. Under dead load only, the minimum freeboard is 14 inches, and the maximum is 24 inches. (c) Weight of seawater, for the purposes of flotation calculations, shall be 64 pounds per cubic foot. (2) The flotation shall use expanded polystyrene cores. 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. 11 ATTACHMENT 2 � \ \ I � . . C2. Loading C2.1 Dead Load (DL) C2.1.1 The total dead load of a floating dock system is the combination of concentrated and uniformly distributed weights of all framing, decking, nuts, bolts, washers, connectors, flotation pontoons, and all permanently attached equipment such as pipes, lines, pumps, utilities, fuel facilities, sewage systems, fire suppression systems, gangways, lighting, storage boxes, utility cabinets, etc. The determination of total dead loads should also include the estimated weight of items that will be stored in storage boxes, and the weight of the fluids in various utility lines and related equipment. Dead Load on a Dock: Electrical Transformer Cabinet C2.1.2 Care must be taken in locating various dead load elements to insure that flat and reasonably level deck surfaces are maintained throughout the service life of the dock system. Overloaded storage boxes or large diameter water lines on only one side of a dock can alter the freeboard and deck slopes. C2.1.3 Cross slopes under dead load only shall not exceed 2% (1:50) on docks that are part of an accessible route. C2.1.4 The dead weight of lumber and wood timbers utilized in a floating dock system should be assumed to weigh not less than 35 lbs. per cubic foot at specified moisture contents following pressure treatment. C2.2 Uniform Live Load (ULL) 25 pounds per sq ft minimum C2.2.1 25#/ftz is a guideline that is time tested and can be relied upon to be reasonable in its application. Floating docks in marinas should meet all freeboard and deck slope guidelines under the minimum ULL. C2.2.1.1 There may be circumstances in which the application of a 25#/ft2 ULL is actually in conflict with practical dock design and construction considerations under unique local conditions. C2.2.2 Snow and ice loads will be part of the ULL in certain locations. Sustained snow loads and ice buildup can exceed 25#/ft2, depending on water FMI content. These loads can linger for weeks or months unless the docks are cleared or warmer weather returns. It is prudent to check with local authorities for required or recommended design snow and ice loadings. SECTION C Berthing - Page 24 C2.2.3 ULL of 40#* may be necessary for design purposes in marina locations where floating dock systems are subjected to regular and repeated high volumes of pedestrian traffic and the movement of goods, materials, supplies, cargo, etc. Special events such as boat shows where queuing for shuttles, ferries, etc., may call for the higher ULL on impacted marinas. C2.3 Live Point Load (LPL) 400 pounds minimum hign volume rt"voul- 9.4I.- C2.3.1 Floating docks in marinas are to meet all freeboard and deck slope requirements under a minimum LPL of 400#, applied at any point on the deck not closer than 129 from any edge. This realistically addresses the center of gravity of the general array of heavy objects that are likely to be roped over the surface of, or temporarily placed upon a marina dock. A typical LPL might be an outboard engine, stacked boxes of supplies for a cruise, or an adult person in a heavy-duty battery -powered wheelchair. The 400# LPL will cover the majority of typical temporary loads that are likely to occur on a marina dock. C2.3.2 Where the application of a heavier LPL is anticipated, especially along an accessible route, design loads require careful attention with regard to freeboard and cross slopes. C2.3.3 Where applied along an accessible route, the minimum 400# LPL shall be applied concurrently with the minimum 2MM z ULL to insure that maximum cross slopes are not exceeded. C2.4 Lateral Loads (WinL, CL, Wavl-, IL) Lateral loads on a dock system may result from winds, currents, waves, and impacts. Such loads may be imparted to docks, boats tied up to docks, or both concurrently. Such loadings may be influenced by seasonal factors that may dictate that two or more types of lateral loads be applied concurrently. C2.4.1 Wind loads (WinL) on the projected vertical surfaces of docks and berthed boats should be not less than 15#/fe, applied above the water surface. If established wind data at specific locations dictates, a higher unit WinL may b necessary. C2.4.2 Current loads (CL) should be calculated on the basis of the maximum currents, flood flows, tidal flows, and/or other site -specific lateral (horizontal) moving water loadings that can be anticipated at a given marina site. The determination of current loads must include consideration of reversals of flow SECTION C Berthing - Page 25 definition of "neap' cannot be identified in terms of feet or miles, but must be determined by the character of the river itself, including bends, tangents, forks, stream flows, velocities, levee characteristics and the presence of other physical features that influence where quantities of debris would likely flow during a flood event. C2.5.2 Wildlife loadina can occur in E marinas, involving ducks, geese, sea lions, harbor seals and other natural residents that live in and near the water. When such a condition occurs with wildlife, it can cause partial or total shutdown of a marina. Along the coast where certain marine animals are protected by federal law, and enforced by NOAA Fisheries, it may be very difficult or illegal to remove wildlife from docks and boats for certain periods of time. When such events occur in a marina, solutions can usually be worked out cooperatively with personnel from federal, state and local environmental authorities. .lea Lions In oomb W bea Dons on uoacs h fi Ac' SECTION C Berthing - Page 27 ATTACHMENT 3 INEWPORT HARBOR YACHT CLUB DOCK REHABILITATION -PHASE II T-1 TITLE SHEET L-0 PHASE I APPROVED PLAN CHECK HARBOR DESIGN CRITERIA STANDARD DRAWING SHEET 01 HARBOR DESIGN CRITERIA STANDARD DRAWING SHEET 02 HARBOR DESIGN CRITERIA STANDARD DRAWING SHEET 03 HARBOR DESIGN CRITERIA STANDARD DRAWING SHEET 04 HARBOR DESIGN CRITERIA STANDARD DRAWING SHEET 05 L-1 EXISTING OVERALL DOCK LAYOUT L-2 DOCK LAYOUT L-3 FLOAT LAYOUT - I L-4 FLOAT LAYOUT - 2 L-5 FRAMING PLAN L-6 FRAMING LAYOUT DETAILS - 1 L-7 FRAMING LAYOUT DETAILS - 2 L-8 SECTIONS & DETAILS P-0 PLUMBING NOTES P-1 PLUMBING LAYOUT & DETAIL FP-0 FIRE PROTECTION NOTES FP-1 FIRE PROTECTION LAYOUT FP-2 CLASS 3 FIRE PROTECTION DETAILS E3.0 ELECTRICAL NOTES, LAYOUT & SINGLE LINE DIAGRAM SOUTHLAND ENERGY CONSULTANTS E2.0 ELECTRICAL DETAILS SOUTHLAND ENERGY CONSULTANTS NEWPORT BEACH, CA SITE ADDRESS: 720 WEST BAY AVENUE, NEWPORT BEACH, CA 92629 OWNER: NEWPORT HARBOR YACHT CLUB 720 WEST BAY AVENUE NEWPORT BEACH, CA 92661 ATTN: TOM HOGAN ENGINEER: TIM BAZLEY, P.E.
