HomeMy WebLinkAbout30A Dining Deck Design Guidelines - Memorandum CITY OF PALM DESERT DEVELOPMENT SERVICES DEPARTMENT INTEROFFICE MEMORANDUM To: Mayor Kelly and City Council L. Todd Hileman, City Manager From: Eric Ceja, Interim Director of Development Services Date: June 24, 2021 Subject: DRAFT Dining Deck Design Guidelines Attached is a draft version of the dining deck design guidelines that have been prepared by Prest Vuksic and Greenwood Architects. These draft guidelines were presented to the City’s Architectural Review Commission (ARC) on June 22, 2021, for their initial feedback. The ARC is supportive of staff’s proposal to have the ARC adopt said guidelines and would like to continue working on the draft design guidelines for refinement. Staff and the ARC support the design guidelines being a living document with periodic review and updates to ensure aesthetic quality is maintained over the long term. Attached: DRAFT Dining Deck Design Guidelines [This page has intentionally been left blank.] OUTDOOR DINING DECK DESIGN GUIDELINES THE CITY OF PALM DESERT Community Development Department ROUGH DRAFT 6-17-21 OUTDOOR DINING DECK DESIGN GUIDELINES The intent of the guidelines for outdoor dining decks is to establish design and construction methods that will result in decks that are both safe and aesthetically pleasing for the public. The design guidelines are outlining a minimum standard, and are not intended to stifle creativity. All submittals will be reviewed on a case by case basis, and will be deemed acceptable (or not acceptable) based on architectural merit, safety, and compliance with these design guidelines. Dining decks are meant to provide additional outdoor seating options for patrons and add another layer of interest to the street scene. APPROVAL AND REVIEW STANDARDS All dining decks must submit a Temporary Use Permit (TUP) for review and approval with the City's Development Services Department. Applicants shall submit drawings, construction methods, site plans, and identify materials used in their dining deck design. Once received, City staff will review the TUP application and submitted materials, for compliance with these Dining Deck Guidelines. SAFETY STANDARDS Please refer to the City of Palm Desert Public Works — Outdoor Dining Deck Design Guidelines for Safety Standards. DECK CONSTRUCTION STANDARDS Decks may use one of the following construction methods: 2x4, 2x6, or 2x8 pressure treated wood covered with a 5/8" min marine grade plywood subfloor. The plywood is to be screwed, not nailed, into the 2x members. The finish may be a non-slip tile or an outdoor carpet. An adequate street drainage system needs to be provided adjacent to the curb. This could be either an open space or metal tube below the deck, or wood framing adjacent to the curb could be raised off the street high enough to allow for storm water to pass underneath it. See Diagram 1. � .r � 1 _ � � 1 } ,t q �. � �� � � � � � �: r'' ..-�,;'. _ �,, �tAr�x��:�i � . �-- _ Page 2 Ideally, the top of the deck, would be at the same elevation as the top of the curb, for an easy transition. This is preferred and encouraged. If the deck is at the same elevation as the curb, provide a suitable metal threshold. See Diagram 2. �- ; �ivt�c o[:c�: i IItESHc)LL) M1� i DL4(iRAM 2 ,� E: . Please refer to the Public Works Design Guidelines for more detailed information about thresholds. If the deck is above the height of the curb, a code-compliant handicap accessible ramp must be provided. All exposed deck edges are to be clad in a 2x wood material with a metal angle on the edge See Diagram 3, or be totally clad in metal and finished with a paint color that meets with City staff approval. DIAC;KAi�i � Page 3 2. Brick pavers over a sand sub-base, over gravel, over two layers of 3 mil visqueen. The top of the brick pavers are to be flush with the top of the curb. The edges of the deck, other than on the curb side, are to be finished with a steel angle or plate. Corners of the steel edging may be connected with steel angles (on the inside) and bolts. The visqueen should extend up the inside vertical face of the edges, except on the curb side. Street drainage is to be provided with a plate steel tube adjacent to the curb. The top of the tube is to be flush with the top of the pavers and the top of the curb. This can also be designed so that the top piece is removable plate steel that drops into place.

" _ � � " `t \ � � _ � � _ - �, / / J \ � � � i As outlined in the City of Palm Desert Public Works barrier design standards in the Dining Deck Guidelines, K-rail or water-filled barricades shall provide the base for the vertical elements. These barriers shall be covered with acceptable materials so that they are not visible. Acceptable cover materials include, but are not limited to metal, ceramic tile, stone, cementitious products, etc. Some of these materials may be applied over a boxed out sub-frame that fits over the k- rail, or water-filled barriers. See Diagram 5. Unlike Diagram 5 however, it is preferred that the entire barrier is covered with the finish material. The acceptability of any material is subject to review. This is because different materials have various levels of quality and attractiveness. They also can be applied in a variety of ways, some of which may be more attractive than others. Page 4 r�r�` - '', �.� � .` .� �. � ��� � � � i � � . � ,� . �' :� Other possible vertical barrier options are 3 dimensional plate steel forms, that could also be filled with soil and plant material to serve as a weighted barrier.

Plant material is encouraged. t � • �. � ♦ I)iAGIZAM 8 Small openings between solid barriers may be permitted. These openings would need to be separated from the street with horizontal cable rail, steel dowels, or some other material that is deemed aesthetically attractive, and acceptable by Staff. This material cannot have any space large enough to allow a 4" sphere to pass through. See Diagram 9. Material selections and methods of application will be reviewed by Planning Staff. Page 6 Ul:�(;kt:\\1 �� s� The following vertical barriers would generally not be deemed acceptable: Vinyl pickets or lattice work, painted wood pickets, plastic sheets, fabrics. Deck Materials �� Brick pavers, and framed plywood decks covered with non-slip tile or outdoor carpeting are acceptable. Note: Tiles and outdoor carpeting are acceptable as a material, but would be reviewed on an individual basis for aesthetic acceptability. Artificial turf is not acceptable. Overhead Covers Overhead Covers may consist of the following: 1. Portable umbrellas of a style and color that is deemed to be acceptable by City Staff. 2. Portable pre-engineered canvas covers with metal poles of a style and color that is deemed to be acceptable by City Staff. Pre-engineered canvas covers would need to be secured by bolting into the deck base, or providing acceptable concrete piers. Sandbags are not acceptable. Li�htin� Lighting may consist of the following: 1. Market style LED lighting which may be strung from nearby trees and/or connected to poles and/or connected to pre-engineered canvas covers. 2. Lantern style lighting. 3. Artificial battery operated candles. Lighting should be 3000 to 2700 Kelvin or warmer. Lighting brightness would be at the discretion of the Planning Staff, but generally, light sources should not cause an unpleasant glare to someone that is not in the deck area. � ". Page 7
