And they are intended to provide a comfortable, valuable setting for a range of diverse housing types that meet the needs of current and future Palm Desert residents. These guidelines are intended to strike a balance between clarity of vision and purpose, and flexibility to meet the market demands and resident aspirations as the neighborhoods are built in a series of phases, and as they mature and evolve over time. These guidelines work hand in hand with the development standards in Section 4 to assist developers, builders, residents and the City of Palm Desert in achieving those goals. Appendix A. Design Guidelines A-2 | 01.07.17 | CITY OF PALM DESERT UNIVERSITY NEIGHBORHOOD SPECIFIC PLAN SECTION A.1 | NEIGHBORHOODS & HOUSING 1. Palm Desert Neighborhoods Palm Desert’s first half century of housing development was characterized by the low wide houses on large lots, with strong emphasis on indoor and outdoor spaces that flow together to deliver the mid-Century desert life-style . Most homes were 1-story, many in the mid-Century Modern and Ranch styles of the 1950’s and 60’s, on lots of 8,000 and 10,000 s.f. with very generous yards and swimming pools. Multi-family housing was provided in the form of apartment complexes, organized around courtyards, gardens and pools, and located separately from single family neighbor- hoods. Recent Development Trends A number of recent Palm Desert housing developments have followed trends popular in the 1990’s and 2000’s, imported from Orange and Los Angeles Counties, with large 2-story houses built on lots as small as 4,000 s.f. and less, many with small patios rather than back yards, and some with no usable yard space at all. The “Missing Middle” The UNSP provides a unique opportunity for Palm Desert to add to this existing housing stock a range of “missing middle” housing options that deliver the generous Palm Desert indoor-outdoor lifestyle in more compact configurations than the original mid-Century prototype. These include single-family detached houses on lots in the 5,000 to 6,000 A.1 Neighborhoods and Housing Recent development trends: new housing products are “packed-into” small lots, yielding little or no usable front yard open space; as a result, on-site open space is reconfigured to side or rear yards. Early apartment complexes were organized around courtyards, gardens, and pools. A quintessential early Palm Desert home, characterized by modern architecture, a seamless transition between indoor and outdoor living space, and an expansive yard with a swimming pool to moderate the hot desert climate. CITY OF PALM DESERT UNIVERSITY NEIGHBORHOOD SPECIFIC PLAN | 01.07.17 | A-3 DESIGN GUIDELINES | APPENDIX A s.f. range, as well as single-family detached and attached types on smaller lots, and a range of neighborhood-scale multi-family types on lots of various sizes. Neighborhood Diversity Also, as observed in towns throughout California and as demonstrated in innovative neighborhood designs of the past decade or two, such a diverse array of housing options can be flexibly intermixed within a single neighborhood if certain basic neighborhood design principles are followed. Such neighborhoods – common throughout the country but not yet present in Palm Desert – can enable young people to live within walking distance of their parents, older couples to find a home near their children and grandchil- dren, and students, graduate students and university faculty to find housing within walking and biking distance of the campus and commercial services. A podium courtyard building achieves increased density,while maintaining quality private and shared open space. A neighborhood-scale courtyard building with 16 units in two individual buildings sharing a common open space. Smaller, houses on smaller lots provide a more affordable housing option to a broader range of potential residents. Individual bungalow cottages arranged around a common open space. As a neighborhood is the fundamental unit of towns and cities alike, the house is the fundamental unit of neighbor- hoods. And while houses and housing can take many forms – larger or smaller, detached from other houses or attached to them – in American neighborhoods the detached single-family house with front, side and rear yards is the essential form, in relation to which other housing types are understood. Thus, to achieve a cohesive neighborhood design in which a variety of different housing types appear harmonious and complementary to one another, it is important that each variation possesses some clear “house-like” and “house- scale” design characteristics. This introductory section describes those characteristics and design strategies, on which the development standards and design guidelines for the UNSP are based. A-4 | 01.07.17 | CITY OF PALM DESERT UNIVERSITY NEIGHBORHOOD SPECIFIC PLAN SECTION A.1 | NEIGHBORHOODS & HOUSING The UNSP offers opportunities for smaller, more intense housing types, on smaller, more compact lots. A mix of architectural styles and building scale / character creates visual diversity in this neighborhood. 2. Neighborhood Patterns The fundamental American house is characterized by a single, simple mass with a gable or hipped roof, set back from the street with a front yard, separated from its neigh- bors by landscaped side yards, with a private rear yard for family activities. Larger houses on larger lots are generated by adding secondary masses in the form of wings on one or both sides, to the rear, and in some cases in the front, and as independent out-buildings in the rear yard. Garages are often located in the wings or outbuildings. A critical strategy in generating a varied but cohesive neigh- borhood design is to ensure reasonable consistency in the size and scale of the Primary Masses of all buildings within a street. Buildings with significantly larger or smaller Primary Masses can comfortably share a rear yard fence or alley, but within each street a degree of compatibility in size, scale and character is very important. That scale and character is defined in large measure by: •The (range of) widths of the lots •The width, height and depth of the Primary Mass, in dimension and in relation to the lot width •The range of front setbacks •The design of the frontages (front yards) •The presence or absence of garages near the street •The consistent (or generally consistent) space between buildings on adjacent lots. The original Palm Desert pattern has been characterized by large, often horizontally massed mid-century modern houses on large lots with generous yards on all sides. CITY OF PALM DESERT UNIVERSITY NEIGHBORHOOD SPECIFIC PLAN | 01.07.17 | A-5 DESIGN GUIDELINES | APPENDIX A A variety of building types -- including this multi-unit courtyard building can seamlessly “fit in” to most neighborhood contexts. A quadplex, in the form of a larger house, fits nicely, both in scale and character, with its smaller single-family neighbor. A duplex with the scale and character of a larger single-family house whose garages are accessed through a porte cochere. A quadplex (left) and a 6-unit multi-plex (right), both of which have the form of larger single-family homes from the street. As such, a cohesive neighborhood character is generated when some, but not all, of these characteristics are varied along a street or within a section of a neighborhood. An important lesson learned from the work of early 20th Century town planners is that houses and lots of varying sizes can be very successfully mixed within a single neigh- borhood if a few basic design principles are recognized. a. Buildings of various sizes on lots of various widths can be mixed within a street so long as the size and scale of the Primary Masses and the depth and design character of the front yard are relatively consistent. b. Much larger (or much smaller) buildings can be located nearby – even back to back or across from one another – so long as the buildings have similar frontage massing, facades, and intensities that match the character of a given block, street and neighborhood. c. The neighborhood design quality – or in later 20th Century parlance, “curb appeal” – is improved by locating service functions such as garages and utility equipment as far as practical toward the rear of the lot. A-6 | 01.07.17 | CITY OF PALM DESERT UNIVERSITY NEIGHBORHOOD SPECIFIC PLAN SECTION A.1 | NEIGHBORHOODS & HOUSING 3. Indoor/Outdoor Living The placement and configuration of the building(s) on each lot determines the sizes and configurations of the yard spac- es. The quality and usefulness of those yard spaces is always an important consideration in designing housing, but in Palm Desert – where the indoor/outdoor desert lifestyle is central to community identity – it is a top-level priority. Early Palm Desert homes and apartments were generally characterized by expansive yard areas with swimming pools and lush landscaping to moderate the hot, dry desert climate. There is no denying the luxury of such spaces, but they demand significant time, energy and water to keep them comfortable for year-round living. As one considers more compact housing forms for more compact neighbor- hoods, there is a significant potential value in well-designed “outdoor rooms” (yard spaces) that are smaller, more shaded and better wind-sheltered. Consistent with Palm Desert’s General Plan theme of sus- tainability – the careful use of non-renewal resources, surely including the resource of land – the housing types defined in the following pages are intended to put every yard area to productive use, often for more than one purpose. Side yards that double as comfortable bedroom patios, drive- ways that double as forecourts, side yards as play spaces for children, semi-public front yards for visiting with neighbors, shared garden courts that provide gathering spaces and ad- A Spanish revival home arranged around a shaded internal courtyard. Car “court” areas, particularly on smaller lots, can double as usable private on-site open spaces. The essence of desert-living; indoor rooms that flow seamlessly into outdoor living spaces, with pools, lush landscaping, and beautiful desert landscape backdrops. CITY OF PALM DESERT UNIVERSITY NEIGHBORHOOD SPECIFIC PLAN | 01.07.17 | A-7 DESIGN GUIDELINES | APPENDIX A In Palm Desert’s hot desert climate, narrower/shallower private on-site open spaces that are shaded from the sun and sheltered from the wind are very valuable amenities. Spaces like these are particularly appropriate to the desired intensity of the UNSP. This sideyard dining patio enclosed by a privacy wall between neighboring lots is great use of private on-site open space. This design pattern could also appear in front yards. This outdoor fireplace is the focal point of this enclosed, shaded patio - a great example of an outdoor room. dresses for multiple bungalows; all of these purposes con- tribute to the seamless flow between indoor and outdoor space that has characterized the desert lifestyle for decades. See Appendix A.6 for further details on On-Site Open Space Guidelines. A-8 | 01.07.17 | CITY OF PALM DESERT UNIVERSITY NEIGHBORHOOD SPECIFIC PLAN SECTION A.1 | NEIGHBORHOODS & HOUSING 4. Neighborhood Lot Organization This section provides design guidelines for the siting and mass- ing of buildings on neighborhood lots, generally organized into four subjects: A. Primary Mass The primary building element in house-form neighborhood buildings is a simple volume, with the following typical characteristics. Section numbers in parentheses provide specific standards and guidelines. a. Size: Generally 20 to 30 feet wide and deep,1 to 2 stories in height (See Sections 4.4 and Appendix A.7). b. Form: Gabled or hipped roof typical, pitch related to style; flat roof possible for modern style (See Sections 4.4 and Appendix A.7) c. Location: Set on or near the front setback line and within the side and rear setback lines (See Section 4.4). d. Orientation: Eaves to the street, with main entry and windows of primary ground floor living spaces overlooking the street (See Sections 4.4 and Appendix A.5) e. Projections: Porches and other frontage elements may project into front yard setback (See Sections 4.4 and Appendix A.5 and A.7), and architectural elements may project into side and rear yard setbacks (See Appendix A.7).

FIG. A.1.1 Typical Neighborhood Pattern CITY OF PALM DESERT UNIVERSITY NEIGHBORHOOD SPECIFIC PLAN | 01.07.17 | A-9 DESIGN GUIDELINES | APPENDIX A B. Wings and Outbuildings Buildings larger than the recommended range for Primary Masses may be generated by the addition of wings and outbuildings, generally as follows: a. Size: Perceptibly smaller in width, depth and height than the Primary Mass (See Appendix A.5 and A.7). b. Form: Similar to and compatible with that of the Primary Mass. c. Location: Must be within all building setbacks. (See Section 4.4). •Side Wings: Set back behind Primary Mass by 3 feet or more. Side wings containing a street-facing garage should be set behind the Primary Mass by 5 feet minimum. •Front Wings: May not project forward of the front setback line and, when provided, should help define a welcoming entry space, such as a forecourt or engaged porch. •Rear Wings: Should help define usable private yard area(s). •Outbuildings: Set back behind the Primary Mass, and usually at or near the side and rear setbacks. Should help define usable private yard area(s). d. Orientation: Typically eaves to the street; front wings may additionally face the street with a gable. (See Appendix A.5 and A.7). Rear wings and outbuildings should orient their primary windows and architectural projections into the lot, not to neighbors. An exception to this is balconies facing an alley. e. Projections: May generally have the same types of projections as Primary Masses, scaled down appropriately and rarely projecting nearer the street than the front building mass. f. Garages: should be located in wings or outbuildings behind the face of the Primary Mass by 5 feet minimum, except when a side-facing garage is located in a forward projecting wing and accessed via a forecourt (See Appendix A.7). A simply massed smaller house with a clearly articulated Primary Mass, side wing and engaged porch. A larger house with a clear Primary Mass scaled-down by a projecting front wing, and projecting 2nd story balcony. Avoid: Complex Applied Massing: This house illustrates extreme, and unnecessary complexity. In addition to the absence of a clear Primary Mass, each room is articulated with its own roof form, creating a cacophonous composition. AV O I D A-10 | 01.07.17 | CITY OF PALM DESERT UNIVERSITY NEIGHBORHOOD SPECIFIC PLAN SECTION A.1 | NEIGHBORHOODS & HOUSING C. Roofs Roof forms should be simple and directly related to the masses they cover. Complex applied massing is explicitly discouraged. This typically results from a lack of resolution of the building plan and building massing and/or an aimless desire to jazz up the curb appeal. Simple, clear architectural expression is the goal. The following general guidelines are provided, see also style-specific guidelines (Appendix A.7). a. Form: Simple gabled masses, eaves to the street are generally preferred. Very low pitched gables facing the street are often associated with the mid-Century modern style. b. Dormers: Dormers are considered an exception to the roof/mass correlation requirement; yet, they are rare in Palm Desert as they are not associated with Spanish revival, mid-Century or Modern styles. Other European revival styles and American Arts and Crafts styles in which dormers are a common device are neither recommended nor prohibited. This carriage house above an alley-accessed garage provides an additional unit and potential for rental income. A side-facing front entry with a garage in a projecting front-wing matches the Mid-Century Modern style of the home. A simply-massed house in a traditional Spanish architectural style with “eaves to the street” and a single street-facing gable. Typical of the Mid-Century Modern style, a very-low pitched gable characterizes the profile of this home. CITY OF PALM DESERT UNIVERSITY NEIGHBORHOOD SPECIFIC PLAN | 01.07.17 | A-11 DESIGN GUIDELINES | APPENDIX A D. Building Spacing Comfortable building to building spacing is an important design characteristic of the UNSP. To provide residences at the smaller end of the spectrum, rather than squeezing single-family detached houses onto smaller and smaller lots with narrower and narrower spaces between them, a range of attached and multi-family housing types are included in the Neighborhood Zones. Such multi-unit buildings, in turn, are provided with comfortable side yard separations from their neighbors. Please note that the design intent is different in the Center Zone, (See Appendix A.1 to A.4). a. Typical Spacing Proportion: Building to building spacing on adjoining lots is generally between 1/4 and 1/3 of the Primary Mass width. b. Minimum Spacing: Minimum building to building spacing from lot to lot must be provided per the setback requirements of (See Section 4.4), and should be wide enough to provide comfortable access (typically at least 10 ft). c. Multiple Buildings on a Single Lot: Spacing between multiple buildings on the same lot should be enough to provide comfortable access between buildings and/or define usable private yard area(s). (See Appendix A.6 for on-site open space guidelines). d. Additional Requirements: Additional building to building spacings may be required for specific housing types (See Sections 4.4 and Appendix A.7). In traditional neighborhoods, buildings are typically spaced between 1/3 and 1/2 of the width of the Primary Mass. In many contemporary neighborhoods, building-to-building spacing has been narrowed, which can be just fine so long as adequate space is provided for comfortable access and daylight. Spacing between multiple buildings on the same lot should be large enough to provide comfortable access between buildings, and/ or provide usable private open space. These bungalow courts exhibit efficient, yet comfortable spacing. A-12 | 01.07.17 | CITY OF PALM DESERT UNIVERSITY NEIGHBORHOOD SPECIFIC PLAN SECTION A.2 | NEIGHBORHOOD HOUSING TYPES A.2 Neighborhood Housing Types Prototypical Pattern: Single-family neighborhoods. Prototypical single-family neighborhood pattern characterized by single houses on single lots with private yards on all sides. A. Introduction The design intent for the UNSP is variation with cohesion, or “organized variety”. This Section provides design guidelines for a selected specific Neighborhood Housing Types that repre- sent the most common applications of the Neighborhood De- sign Guidelines described in Appendix A.1, and the most typical examples found in most traditional American Neighborhoods. Types other than those described in this Section may be pro- posed, so long as they are found to conform to the Neighbor- hood Design Guidelines of Appendix A.1, and follow common sense design strategies including: •If a building is taller than a neighbor, it should not also be significantly wider or deeper. •If a large house is nearby much smaller homes, its Primary Mass should be in the same size range, and the larger house is generated by adding on wings not just inflating the Primary Mass. •If a building contains 2 or more dwellings, its Primary Mass shares the scale and character of nearby houses. •As lot widths vary, the house size and the house-to- house side yard spacing remains in proportion to the lot width to foster comfortable spacing and privacy between homes. A row of single family side yard houses with dooryards as a frontage. B. Neighborhood Housing Patterns The single-family house is the basic unit of measurement that all other neighborhood housing types are based upon. This form can be scaled-up or scaled-down, and arranged in a variety of configurations to achieve increased building intensities in the context of a traditional neighborhood pattern. In addition to the various configurations of the prototypical single family house, this Section describes a variety of multi- unit neighborhood housing types that may be quite freely intermixed with houses in certain neighborhoods by virtue of their adherence to the neighborhood patterns. CITY OF PALM DESERT UNIVERSITY NEIGHBORHOOD SPECIFIC PLAN | 01.07.17 | A-13 DESIGN GUIDELINES | APPENDIX A Variation #1: Multiple houses “attached” This variation attaches 3 or more smaller-scale house form buildings to create a larger buildings. Individual (or groups of) units with expressed massing of “house form” and “house scale” massing elements ranging from 15 to 25 feet wide. This enables larger buildings to be comfortably intermixed with smaller buildings and houses. Due to the limited amount of on-site open space afforded by this type, it is most appropriate near or adjacent to a public open space. Variation #2: Multiple houses on a single lot. In concept, this variation replaces what would be a typical building lot within a neighborhood with an open space, and orients multiple units around that open space to form a shared-green. The street-fronting masses on either side of the green are of the same form, scale, and character of the existing neighborhood pattern. Variation #3: Multi-units houses single lots. This variation simply involves replacing single-family houses in a neighborhood pattern with houses of the same form, scale, and character of neighboring buildings, that happen to have two or more individual units within the same build- ing. As such, care must be taken to choose buildings of an appropriate scale that can fit seamlessly into the existing (or intended) neighborhood pattern. C. Neighborhood Housing Types Common applications of these neighborhood patterns are described in the pages that follow, organized into the these Neighborhood Housing Types: Neighborhood Housing Types Page a. Rear Yard House A-14 b. Side Yard House A-18 c. Carriage House A-20 d. Bungalow Court A-22 e. Duplex, Triplex, Quadplex A-24 f. Neighborhood Rowhouse A-26 g. Villa Apartment A-28 h.

This variation characterized by larger, multi-unit “house forms”, with the scale of neighboring single-family houses. This variation is characterized by arranging a number of houses or units around a common open space, or “courtyard.” This variation attaches 3 or more small “houses” into a single building, in scale with neighboring buildings A-14 | 01.07.17 | CITY OF PALM DESERT UNIVERSITY NEIGHBORHOOD SPECIFIC PLAN SECTION A.2 | NEIGHBORHOOD HOUSING TYPES 1.

Rear Yard House The Rear Yard House is a detached single-family house whose main living spaces are oriented to the street to welcome the visitor, and also to a private rear yard area for family activities. This configuration is suitable for a range of lot sizes, from narrow to large. A carriage unit (See Page A-20) may be built at the rear of the lot.

Architectural elements such as balconies can help reduce the visual prominence of a front garage. A cantilever over a garage achieves a similar effect as a balcony. Splitting a garage entry into two separate doors can help mitigate the visual effect of a garage 1. Design Strategies for Front Garages •Emphasize the front entry to the home with architectural elements such as porches, stoops or balconies. The entry yard should be well defined and landscaped to extend a welcoming gesture to the street. •Large-scale elements over garage doors – including balconies, projecting rooms and double or triple windows – help balance that facade composition. •Simple restrained massing is recommended rather than the alternative technique of adding many small gables and projections. •Where practical, a pair of 1-car garage doors rather than a single double door can improve the scale of the facade. Double garage doors can also be simply designed to mimic the scale of a pair of single doors. •On modern buildings, carports may be incorporated that are in line with the front facade of the house.

Bungalow Court The Bungalow Court is an arrangement of four or more detached single-family houses around a shared courtyard or greenway, which provides direct access to all houses that do not directly front on a street. The Bun- galow Court is an efficient and flexible type particularly suitable for deeper blocks. Since only the two end units abut the street, the Bungalow Court is compatible with predominantly single-family neighborhood streets. Bungalow court units may be the scale of a normal single-family home.

Mixed-Use Neighborhood Centers Mixed-use neighborhood centers provide a concentration of useful destinations within a network of comfortable public spaces in which nearby residents, shoppers, visitors and employees can run daily and weekly errands, lunch or dine, and meet friends and neighbors. Such centers are character- ized by ground floor shops, restaurants and offices – along with upper floor offices and residences – lining and defining the shared open spaces of the center that include the streets and sidewalks, arcades and paseos, balconies and roof ter- races, and courtyards, squares and parks. While Palm Desert’s neighborhoods are characterized by houses and other building types with strong house-form characteristics, its commercial and mixed-use centers are generally characterized by simple, boxy, “block-form” build- ings. Such buildings have made up American town centers – whether downtown districts, main streets, or mixed-use centers along the edges of neighborhoods – from the colo- nial period until now. Such buildings made up the original commercial center of Palm Desert along the Highway 111 frontage roads, they populate the City’s landmark El Paseo shopping district, as well as the suburban shopping centers throughout Palm Desert. Multi-family residential buildings that are not part of neighborhoods with single-family hous- es often take on block-form characteristics as well. A.3 Neighborhood Center Design Guidelines Recent development trends: in southern California have tended toward “destination” retail centers which are most often isolated from surrounding neighborhoods. El Paseo showcases a variety of simple, elegant block-form buildings that would enhance most neighborhood centers. A neighborhood center in Palm Desert along El Paseo. This row shows a mix of modern and traditional storefronts, with a variety of shopfront designs and sizes. CITY OF PALM DESERT UNIVERSITY NEIGHBORHOOD SPECIFIC PLAN | 01.07.17 | A-33 DESIGN GUIDELINES | APPENDIX A Block-Form Buildings Block-form buildings are compact and virtually universal in the centers of towns and cities, providing flexible opportu- nities for retail uses at the ground floor, for office or residen- tial uses on upper floors and often on the ground floor as well. The design and use characteristics that distinguish a series of sub-types for various contexts include: •The size and scale of the building in terms of height, width and depth, as expressed by the building’s massing and architectural facade composition. •The design and use of the ground floor at the street frontage, whether open to the street with clear glass shopfronts for retail or restaurant uses, set back behind shallow door yards or up on porches or stoops to generate a degree of privacy for ground floor residential uses, or some intermediate condition appropriate for ground floor office space or other non- residential, non-retail use. •The implementation of building articulation techniques (See Appendix A.4) that help buildings adapt to a proper scale and character pertinent to neighborhood centers. •In addition to streets, such buildings often front onto town squares, public greens, or other public open spaces. Along with town center streets, such spaces function as “community living rooms” for shopping, dining, recreation, and special community events. A series of small mixed use buildings with separate entrances for residential and commercial uses, both within a dooryard. A Neighborhood Center building that properly includes shopfront windows on both facades. A walkable urban center with a variety of shopfronts and amenities. •In some cases such buildings may also enclose on- site semi-public or semi-private open spaces such as courtyards or gardens. •In walkable urban centers, parking is located on the street and in lots or structures behind the buildings, whereas in suburban shopping centers or business parks, buildings are set back from the street behind landscape buffers and/or parking lots.

Intimate paseos and courtyards provide shade for diners and shoppers 2. Indoor / Outdoor Community Space The main purpose of a neighborhood center or town center is to provide a concentration of useful destinations within a network of comfortable public spaces in which nearby residents, shoppers, visitors and employees can run daily and weekly errands, lunch or dine, and meet friends and neighbors. The simple block-form buildings of these centers provide ground floor shops, restaurants and offices – along with upper floor offices and residences – lining and defining the shared open spaces of the center that include the streets and sidewalks, arcades and paseos, balconies and roof ter- races, and courtyards, squares and parks. In Palm Desert’s often harsh climate, it is critically important that outdoor gathering spaces offer generous amounts of shade and wind protection. This provided by a coordinated combination of public and private improvements including: •Multi-story buildings set close to the street, providing a sense of spatial enclosure, shade, and wind protection. •Street trees along the sidewalks providing shade for pedestrians and for parked cars. •Ground floor frontages that help shade the sidewalks shopfronts with awnings, galleries and arcades. A plaza enclosed by properly scaled buildings. Proper landscaping, the implementation of outdoor dining and street furniture, and a mix of uses help to keep the space usable and vibrant. CITY OF PALM DESERT UNIVERSITY NEIGHBORHOOD SPECIFIC PLAN | 01.07.17 | A-35 DESIGN GUIDELINES | APPENDIX A Block form buildings, in their design, should promote places for people to linger, relax, and stay cool. Buildings with residential upper floors should utilize shaded outdoor roof terraces when possible. Deep arcades and galleries are comfortable shaded places for activity to occur. Shared courtyards are valuable amenities for shopowners, residents, and visitors. •Paseos and courts that provide shady and wind protected semi-public and semi-private outdoor spaces within which for commercial and/or residential use. The building standards and guidelines (Appendix A.7), the Private Frontage Design Guidelines ( Appendix A.5), the Public Frontage Standards (Section 3.4) and the Landscape Design Guidelines ( Appendix B) are coordinated to provide clear but flexible guidance for integrating each building with the spaces around it to deliver such environments. A-36 1 01.07.17 | CITY OF PALM DESERT UNIVERSITY NEIGHBORHOOD SPECIFIC PLAN SECTION A.3 | NEIGHBORHOOD CENTER 3. Neighborhood Center Variations (by context) While there is an endless variety of buildings and places that can be generated from block-form buildings, within the UNSP, there are three specific types of environments they are intended to create: A. Mixed-Use Cores The core of a Neighborhood Center or neighborhood center is the most lively, active part of the town or the neighbor- hood, is characterized in large part by ground floor com- mercial use and providing an environment welcoming to all throughout the day and into the evening. Main Street: The most common pattern for such a mixed- use core is prototypically a continuous row of shopfronts along a wide shaded sidewalk with convenient customer parking at the curb. In order to provide a well-defined space for shopper and other pedestrians, most of the parking is located behind – or in some cases beside – the buildings, with parking in front limited to street parking. Town Square: In addition to mixed-use main streets, such buildings and their shopfronts may also front onto a town square or other public space. In such cases, the same wide shaded sidewalks with continuous rows of shopfronts are provided along one side of the street, with the square or other open space on the other side. And in some cases shopfronts may face onto both sides of a retail square or paseo without an intervening street, although the retail viability of such spaces can be challenging.

CITY OF PALM DESERT UNIVERSITY NEIGHBORHOOD SPECIFIC PLAN | 01.07.17 | A-37 DESIGN GUIDELINES | APPENDIX A Such mixed-use cores are envisioned in at least two loca- tions in the UNSP, one a small main street south of Gerald Ford Drive and the other a town square and main street pro- viding the primary neighborhood entry from Frank Sinatra Drive. The size of these cores, as defined by predominantly commercial ground floor use, will be calibrated by market analysis at the time of final design. Buildings within a Neighborhood Center may range from 1 to 3 stories, but the street level activity and character should remain continuous.

LIVE/ W O R K COURT RO W H O U S E B. Neighborhood Greens Whereas mixed-use centers generally occur at the edges of and in between neighborhoods – where there is more vehicular traffic, foot traffic and customer flows to support businesses – neighborhood centers of a different kind can be formed around a park or green, the soft heart of a neighborhood where children play and families gather. Such shared community open spaces can create unique and valuable addresses, and by their size invite buildings larger than houses to define their edges and provide more house- holds with a park-front address. Apartment buildings, row houses, and even live-work buildings can take advantage of these very special frontages, activating and overlooking the edges of the park. CITY OF PALM DESERT UNIVERSITY NEIGHBORHOOD SPECIFIC PLAN | 01.07.17 | A-39 DESIGN GUIDELINES | APPENDIX A C. Neighborhood Transitions At the edges of the Neighborhood Center - at the interface between the mixed-use core and adjoining neighborhoods - a mixture of small-scale block-form buildings and house form multi-family and attached housing and can provide a seamless and valuable transition. These transitions generally include attached, single family row houses, flex- ible live-work row houses, quadplexes and duplexes, and neighborhood-scale apartment buildings with and without courtyards. Within this transition, neighborhood-scale block-form buildings may be mixed quite freely with the house-form multi-family types described in Appendix A.2. These types collectively constitute what has become known as the “missing middle” – a rich variety of development types forgotten for many years as the development industry focused on single-family houses, apartment projects, and strip shopping centers.

Lot Organization The buildings of the UNSP’s mixed-use centers are specifically intended to be of the “walkable urban“ type rather than “auto-oriented suburban”, meaning they face pedestrian oriented streets and that parking is provided on those streets as well as in parking lots behind or beside the buildings (or otherwise), but not in “front yard parking lots”. A. Building Size & Scale Buildings are intended to be “town scale” rather than “city scale”, meaning that their size and scale should not be dramat- ically greater than that of the housing in the neighborhoods. (See Sections 4.4 and Appendix A.7). a. Building Heights: Heights range from 1 to 3 stories, only up to 1 story taller than the house- form neighborhood buildings. It is worth noting that in mixed-use centers – as distinct from the neighborhoods – building height is a generally desirable characteristic that serves to form the walls of this outdoor room for community activity. The common practice of building up “false fronts” on 1-story buildings in the early town centers of the West was a simple technique for generating a “sense of place” in the middle of an open prairie or desert, while waiting for the growing economy to bring multi-story buildings. Contributing to the building height, ground floors have tall to very tall ceilings to provide elegant settings for retail shops and restaurants filled with natural light. A mix of block-form building types with a proper variety of building heights, scales, and roof forms. 1-story block form buildings use elements such as clerestory windows and parapets to achieve greater height Buildings and frontages form an “outdoor living room.” CITY OF PALM DESERT UNIVERSITY NEIGHBORHOOD SPECIFIC PLAN | 01.07.17 | A-41 DESIGN GUIDELINES | APPENDIX A b. Building Widths: Widths – or apparent widths, as expressed by massing articulation and façade composition patterns – are in the 20 to 60 foot range, not dramatically different from the widths of small houses or large houses. Shopfront bay widths of 20 to 30 feet are typical, and allow a wider building with multiple bays to be perceived as “in scale with” a narrow building that might be only 20 feet wide overall. c. Building Depths: Depths are generally limited to 60 feet or less, but may be deeper for a limited number of larger retail uses. The typical depth corresponds with a typical retail space and with typical upper residential or office floors and, again, is not dramatically greater than the dimension of larger houses in the neighborhoods. It is very important that second or third floor masses not exceed this depth, and that any such masses be articulated as described below. B. Building Siting & Setbacks Buildings are placed purposefully on their lots to generate the types of active, mixed-use, pedestrian-oriented environ- ments described above. See Sections 4.4 and Appendix A.7 for detailed requirements. a. Front Setbacks: Buildings are set on or near the front property line to form a relatively continuous street wall that defines the “outdoor room” of the street and the mixed-use town or neighborhood center environment. b. Side Setbacks: Side yard setbacks are not required and are generally discouraged, but may be provided to create paseos for pedestrian access from the street to rear parking areas or to allow side windows for upper floor residential or office uses. c. Rear Setbacks: Usable rear yards are not required but may be provided for residential buildings. More commonly the rear portion of the lot will be used for parking and deliveries. Taller buildings, such as urban courts, will often provide more open space than others. Setback areas can be and should be pleasantly landscaped environments for pedestrians to experience. Shopfront bay widths help maintain a consistent experience along the street, even if the architectural character varies. A-42 1 01.07.17 | CITY OF PALM DESERT UNIVERSITY NEIGHBORHOOD SPECIFIC PLAN SECTION A.3 | NEIGHBORHOOD CENTER C. Roof Forms: Block-form buildings generally – but not necessarily – have flat roof with parapet walls. They may equally have pitched roofs – always with eaves to the street – sometimes cov- ering the entire building and sometimes false roofs facing the street. This practice – generally discouraged in favor of “4-sided architecture” on free-standing suburban buildings – works perfectly on buildings that are part of a continuous row along a main street. (See Appendix A.7). A commercial building with a typical flat roof and parapet. An example of a false roof along a continuous row of buildings on a main street. Block-form building roofs may also use elements such as towers and roof terraces when appropriate. CITY OF PALM DESERT UNIVERSITY NEIGHBORHOOD SPECIFIC PLAN | 01.07.17 | A-43 DESIGN GUIDELINES | APPENDIX A A.4 Neighborhood Center Building Types A Neighborhood Center block showing 2-story mixed-use A. Introduction As observations of classic American main streets will reveal, the architectural composition of the facades – together with subtle or not so subtle variations in facade height – can pro- vide an essentially flat-fronted building mass of 100 or 200 or even 300 feet in width with the authentic appearance of a row of town-scale buildings. The origin of this pattern in California arose from the original platting of the town cen- ter lots, where lots were typically sold in increments of 24 or 25 feet. This resulted in individual buildings of that width or double or sometimes triple that width, with shopfronts and upper floor window groupings that reflected that module, establishing a clear, simple rhythm for the streetscape. Block-form buildings in the centers of the UNSP are in- tended to reflect this classic California town scale, by their width, by their massing, and by their façade design. Please note that successfully applying this subtle type of façade articulation to new buildings requires a good degree of design skill, without which buildings can rapidly take on an unfortunate Disneyland-gone-wrong appearance. Subtlety, restraint, good quality materials and detailing, and a keen eye for proportion are required. While block-form buildings include everything from a town- house to a skyscraper, there are three basic variations: The Flex-Block, Townhouse, and the Apartment building. Within the UNSP we describe the following four (4) types, for each of which a range of variations are both available and anticipated: Neighborhood Housing Types Page a. Mixed-Use A-50 b. Rowhouse A-54 c. Live/Work A-56 d. Urban Courtyard A-58 SECTION A.4 | NEIGHBORHOOD CENTER BUILDING TYPES A-44 | 01.07.17 | CITY OF PALM DESERT UNIVERSITY NEIGHBORHOOD SPECIFIC PLAN Variation #1: Flex-Block Building 1. Description The defining characteristic of this type – also commonly known as a “mixed-use Main Street building” – is a com- mercial ground floor with shopfronts, set at the back of the sidewalk or close to it. Building heights range from one to three stories in height, and the uses of the upper floors may be office or residential or both. Parking beyond the street parking at the curb is provided in parking lots or structures within the block behind the building, in a basement or podium beneath the ground floor, or in shared lots or structures nearby. These buildings are typically built in a continuous row, without side yards, in order to provide a continuously interesting experience for shoppers, and to form a con- tinuous “street wall” that is the hallmark of main streets and town centers. The degree of enclosure provided by such 2 to 3-story buildings on both sides of a reason- ably narrow street is a great amenity in a place with Palm Desert’s extremes of temperature and wind. In some instances it is necessary to build more mod- estly and/or to provide more parking to meet market constraints, and a single-story commercial building set behind a wide and comfortable sidewalk with nicely screened parking beside it can find a place in centers where the taller more continuous main street pattern is predominant. As in every aspect of design, balance is the key, and if such small buildings predominate, you just have a strip mall, not a mixed-use center. A continuous street wall formed by buildings with different upper story setbacks. A tall 1-story retail building on a corner with an appropriate amount of shopfront and interesting roof form.

Articulation Methods Varying Building Heights. Mixed-use buildings in neighborhood centers may vary heights along a block. Although the roof lines may differ, the buildings are united by the commonality of their shopfronts. This creates a continuous experience for the pedestrian at the street level while preserving a dynamic street wall. Incremental Massing. Wide buildings may use facade composition to divide the building into separate, incremental visual pieces. For instance, a tower or gabled end bays can help introduce visual accents through facade composition, helping to reduce the potential monotony of a wide, continuous building. Facade Recessions. Recessions in facades, whether they be for dining areas, entries, or arcades, can help articulate a row of mixed-use buildings. They also allow for a shaded environment along the street. Recessions, such as arcades, help create pleasant pedestrian environments. A tower used as a way of visually articulating a large building. Gradual massing and building articulations may be accented with varied colors, roof lines, gables and facade finishes.

A row of modern townhomes with adequate front yard landscaping. Variation #2: Townhouse 1. Description Townhouses are simply houses that have dispensed with side yards in the interest of generating a compact town center or neighborhood center. Townhouses prototypically have front yards (usually shallow ones in the form of door yards) and rear yards (between the house and a detached garage behind.) They also come in a “tuck-under” variation, with the garage occupying the rear portion of the ground floor. Another very interesting town house variation is the flex house – or live-work town house – wherein the ground floor at the front is designed to accommodate a small business with a private residence upstairs. Access to the residence is generally provided independently from the ground floor business, so that the resident can choose to operate a business or lease the ground floor to another. Additionally, the ground floor may simply be occupied by the owner as an extension of the resi- dence, with the door yard at the front offering a degree of privacy for the residence. Because of this flexibility, such buildings can generally be financed with a stan- dard residential mortgage.

Townhouses in Charleston that use color and material changes to modulate individual units. A pair of townhouses with different heights, but a common frontage along the street. 2. Articulation Methods Varying Building Heights. Townhomes in neighborhood centers may vary heights from unit to unit. Although some may have a third story, or an access tower to a roof terrace, the buildings are united by the commonality of their frontages. This creates a continuous experience for the pedestrian at the street level while preserving a dynamic street wall. Bay Articulation. Townhomes and Live/Work buildings should express each individual unit through either building massing or architectural elements. Architecturally, repeating elements such as stoops, porches, upper floor terraces, etc. can help create a repeating module that break up long facades and express individual townhouse units. See Section 5.7 for full guidelines. Facade Projections. When individual units include a projecting mass or wing, a rhythm is created along the street. Implementing a frontage type such as a dooryard or stoop can help create a commonality between the units. SECTION A.4 | NEIGHBORHOOD CENTER BUILDING TYPES A-48 | 01.07.17 | CITY OF PALM DESERT UNIVERSITY NEIGHBORHOOD SPECIFIC PLAN A simple apartment building without ground floor retail A modern 3-story apartment building Variation #3: Apartment Building 1. Description Block form apartment buildings are essentially flex- block buildings with residential ground floor, and thus set back a bit from the sidewalk. They are distinguished from suburban “apartment complexes” in that they are individual buildings, each fronting directly onto the street, or in some cases onto a semi-private court or garden. Parking is located behind, beneath or in some cases beside the buildings. Whereas townhouses are dwellings that each have a front door to the street, apartment buildings generally have a single shared entrance – the predominant archi- tectural feature of the façade – that provides visitor ac- cess directly from the street, generally via a lobby, stairs and elevator. A desirable – but not required – feature of such buildings in a mixed-use center context is direct access to ground floor units from the street, often via a stoop, which can enhance the sense of connection be- tween the building’s residents and their neighborhood. An apartment building variation that is very well-suited to Southern California and the desert is the courtyard apartment building. The benefits of this configura- tion are many and include modulation of the building scale as viewed from the street, and enclosure of a sociable semi-private, gated or un-gated, shady and wind-sheltered space for residents. Around such a court – or garden – dwellings may be organized as 2-story townhouse type units or flats, with ground floor units accessed directly from the court via front doors, and upper floor unites accessed via individual or shared stairs and sometimes by elevator.

Articulation Methods Incremental Massing. Wide buildings may use facade composition to divide the building into separate, incremental visual pieces. For instance, a tower or gabled end bays can help introduce visual accents through facade composition, helping to reduce the potential monotony of a wide, continuous building. Courtyards. A strong way of articulating apartment buildings is through the use of courtyards. This ensures, in both larger and smaller buildings, that all units have access to an open space. When the courtyard is positioned along a street, the facade of the building recedes to accommodate the courtyard, creating a less intimidating street wall. See Section 4.4 and Appendix A.6 for guidelines. Facade Recessions. Recessions in facades, usually at major entries, can help articulate the street level of apartment buildings. They also allow for a shaded environment for people accessing the building. Architectural Elements. Porches, terraces, and window bays can be used to create visual rhythm along an apartment building. See Appendix A.7 for guidelines. An apartment building that creates a unique, repeated bay consisting of projecting windows and shaded porches.

VARIATIONS Mixed-use buildings, when in groups of two more, should be implemented in one of two basic contexts. The first, the “Main Street” variation, represents a pattern of several mixed-use buildings in a linear arrangement adjacent to a street, usually with more mixed-use or retail uses across from them. This is the most common traditional arrangement of Mixed-use building types in American towns and cities. The second context type includes a similar grouping of mixed-use buildings fronting on or adjacent to a green or other form of public open space. On larger greens and other appropriate circumstances, paseos, courts, and other ways of continuing open spaces into the blocks are encouraged. In neighborhood transition areas, a lower density from of mixed-use buildings around a green may be implemented.

CITY OF PALM DESERT UNIVERSITY NEIGHBORHOOD SPECIFIC PLAN | 01.07.17 | A-61 DESIGN GUIDELINES | APPENDIX A A.5 Private Frontage Design Guidelines Private Frontages encourage activity, promote interaction, and enliven streets. A. Introduction Building frontages - the ground floor face of the building and the space between the building and the sidewalk - de- fine not only the character of each building but collectively define the character of the neighborhood and of the town. Frontages that welcome visitors and other pedestrians are perhaps the most important single design element of walk- able neighborhoods, providing the streets and other neigh- borhood open spaces with a comfortable, human-scale, lived-in appearance. On a functional level, the frontage is the transition between the public realm and the private realm, providing a critically important “privacy filter” between the fully public street and the private interior spaces of dwellings. A series of frontage types are defined here, ranging from deeper front yards - with and without porches or stoops - for a good degree of privacy, to shallower dooryards and stoops and terraces for a moderate degree of privacy, to shopfronts, galleries and arcades that are designed to bring commercial displays right up to the sidewalk - the opposite of privacy. In the climate of Palm Desert and the surrounding Coach- ella Valley, frontages provide an invaluable opportunity for well-shaded areas of respite from sun and heat. Porches on homes, and arcades, galleries and awnings at shopfronts are just some of the many ways that private frontages can create shaded transitional spaces that foster and active, outdoor, and social lifestyle. On a social level, frontages are where neighbors can interact with neighbors on comfortable terms. A landscaped door- yard provides the chance for a resident to maintain a small garden and chat with neighbors, a porch or stoop a place for a homeowner to sit and relax in a shade semi-public, semi-private environment. Porches, front yards and door- yards let the resident invite initial interaction with pass- ers-by without the commitment of inviting guests in. In the Neighborhood Centers, the frontages are the places where chance encounters with people you know and people you don’t yet know occur, shopping, dining or just strolling. And unlike shopping centers, these are places to go when you just want to be in public with others - no purchase required. Within the UNSP we describe the following types; for each, a range of variations are both available and anticipated: Private Frontage Types Page A. Porch A-62 B. Stoop A-64 C. Dooryard A-66 D.

Description The Front Yard is the area between the building façade and the street, providing pedestrian access from the street to all buildings and dwellings on the lot, as well as a physical separation from the street and a semi-public space for play and greeting one's neigh- bors. Front yards may be visually continuous with adjacent yards with a common landscape, or enclosed by a low fence, wall, or hedge. On sloping sites, front yards may be raised above the level of the adjacent sidewalk and supported by a low retaining wall at the property line with steps providing access between the sidewalk and the yard (Dooryard). Frontage types and architectural elements may encroach into Front Yards, as allowed by the zone. A. Front Yard 2. Configuration and Size a. The Front Yard is the area between the Primary Street facing building facade and the Primary Street property line. On corner lots, the Front Yard also includes the area between the Side Street facing facade and the Side Street property line up to the fence enclosing the back yard. See Figure A.6.1 below. b. Front Yard Courts may extend to the Primary Street and/or Side Street Setback area(s), but the portions within the primary or side street setback areas do not count towards the minimum Required On-Site Open Space of each individual zone. c. Dooryards, porches, stoops, and architectural elements may encroach into the Front Yard as allowed by each individual zone. Si d e S t r e e t Primary Street Alley (where present) This front yard is enclosed by a low wall. Area that is required to be landscaped and maintained by the owner or homeowners association. FIG.

Front yard facing a shared courtyard in a multi-family building. 3. Design Front Yard Landscape. Except for walkways, front yards should be planted with trees, shrubs, decomposed granite (DG) or other appropriate ground cover, paving and water conserving plant materials. Front yard landscape should be maintained in an orderly and neat condition. Parkway Planting. Street trees of an approved type should be provided in the planting strip between the sidewalk and the street. Parkways should be planted with water conserving plant materials. Parkways along commercial uses may be omitted at appropriate locations to allow for pedestrian access. Street trees should be accommodated in tree wells. Front Yard Fences. Front yard fences, wall materials and landscaping and designs should be compatible with the architectural style of the building. Front yard fences, walls, and hedges should be no taller than 3 feet-6 inches above the adjacent sidewalk or as defined for the applicable Zone. On corner lots, fences and walls along the side street frontage may be up to 6 feet high for the rear portion of the site up to 15 feet behind the primary street facing facade line (see Figure A.6.1). Fences along the remaining side street frontage may be up to a maximum of 3 feet-6 inches high or as defined in the Design Guidelines for the applicable Zone. Raised Front Yards (Door Yards) should be up to a maximum of 3 feet-6 inches high above adjacent sidewalk or as defined in the Urban Guidelines for the applicable Zone.

Description A Court is a semi-public, shared open space within a lot, for use by more than one resident or tenant. It is a well-defined, coherent area that is an essential com- ponent of the project's design, not merely space left over after the building mass is placed. Courts generally provide visitor access from the street to dwellings, retail or office spaces, and/or buildings within the lot that lack direct frontal access from the street. The degree of en- closure or openness may vary, as per the requirements of each zone and the design intent of the project designer. 2. Configuration and Size a. Configuration. Courts – particularly the portion of the court(s) that is intended to meet the minimum Required On-Site Open Space area requirements of each individual zone – should be placed in the following ways: Side Court. The Court is placed along the side yard of the parcel to work together with a court or back yard on an adjacent lot to create the effect of one large open space; Provide a contiguous space for entrances to a neighboring existing building that face the proposed project and are located close to the property line, to face; When the adjoining lot contains a single-family house, to create a large open space next to the house. Open to Street. The Court adjoins the minimum Primary Street setback line creating a deep, combined garden/terrace facing the street. Internal Courtyard. The Court is an internal courtyard, entirely contained within the site. Special Circumstances. When a site contains an exceptional feature, such as a large, healthy tree or topography, the Court is placed to retain and take advantage of that special feature. b. Size. Refer to Section 4.4 for applicable Zone minimum and maximum dimensional requirements. c. Enclosure. In general, a Court's perimeter should be defined by walls on at least 2 sides, and on a third side by walls or architectural or landscape elements such as low walls or trellises, or linear landscape elements such as hedges or rows of trees. In some cases, one side of a Court may be defined by a building wall or a linear landscape element on an adjoining property. Driveways located adjacent to a Court may be screened by architectural elements such as low walls or trellises, or linear landscape elements such as hedges or rows of trees so as not to appear to be located within the Court. d. Encroachments into Courts. Dooryards, stoops, and architectural elements may encroach into the Court as allowed by the Guidelines of each Zone. FIG. A.6.2 Side Court Examples FIG. A.6.3 Open to Street Court Examples CITY OF PALM DESERT UNIVERSITY NEIGHBORHOOD SPECIFIC PLAN | 01.07.17 | A-81 DESIGN GUIDELINES | APPENDIX A 3. Design Common Area. Courts should be designed to be gathering places for the occupants and also circulation spaces through which pedestrian access is provided from the street to any buildings (or portions of buildings) that lack direct street frontage. Courts should provide a central, flat area that is usable and encourages human activity and interaction. This area should contain a combination of paving and landscaping. Private Area. Courts should be designed to provide for private access to dwellings and businesses that lack direct street frontage. Courts should also provide space for private outdoor space in the form of private patio and terrace spaces. Amenities. Courts should include public amenities such as seating areas, fountains, BBQ islands and/or outdoor fireplaces to encourage their use as common outdoor rooms or gathering places. Finishes. Court materials, finishes, fixtures, and colors should be designed in a manner that is consistent with the architectural language of the building. Landscape. Except for paved areas, courts should be planted with trees, shrubs, DG or other appropriate ground cover and water conserving plant materials. Arbors, trellis structures and raised planter/seating walls are encouraged. Court planting may be in permanent planters The top of walls of planters should generally be no taller than a bench, but some may be up to waist height if so required to support the health of plantings. Trees scaled to the space are generally recommended for shade and to screen views to and from neighboring buildings. The side courts of these two buildings work together to create a single space. An internal court with a fountain as its focal point. A court that provides outdoor dining.

CITY OF PALM DESERT UNIVERSITY NEIGHBORHOOD SPECIFIC PLAN | 01.07.17 | A-93 DESIGN GUIDELINES | APPENDIX A A.7 Architectural Guidelines A. Introduction 1. General Since Palm Desert was founded in 1945, developers have been building neighborhoods and communities that have been unique to the Coachella Valley. Many early developments advertised the area for its local amenities, weather and lifestyle. Today, thousands of people live in and visit the area for its rich desert heri- tage, a result of cultural traditions and environmental traditions. 2. Building Traditions Prior to World War II, the Coachella Valley was home to a handful of very small, quiet communities. As con- flict overseas came to a close, more and more peo- ple looked to the area for recreational and vacation opportunities. Early flyers and advertisements for Palm Desert developments boasted the ease of being able to walk and bike to local amenities such as theaters, schools and churches. The Shadow Mountain Club and Palm Village, both developed in the late 1940's, were some of the first developments to advertise Palm Desert as an "all-inclusive" town in the desert. As El Paseo developed, these communities also touted the adjacency to local neighborhood services and restau- rants. The manner in which the city grew was partially based on the idea that it was a vacation community, both for locals from Los Angeles, and for people across the country. Even though it developed at a time when the car was becoming ubiquitous in American culture, Palm Desert had to cater to visitors who had come a long distance to stay at a resort or club. Guest cottag- es were often a modest size, and major recreational activities and services were within walking distance to most homes. Eventually, the need for year-round housing grew at a rapid rate, and mass-market developers eyed the Coachella Valley for their next ventures. Builders such as the Alexander Construction Company were able to prolifically erect homes with modern materials and modern designs, using the same collection of stan- dardized floor plans. Mass-produced Mid-Century and Ranch homes were laid across wide lots all across the Valley within a few decades. By the late 1970's communities shifted to become more insular, and many new developments chose to have a more private atmosphere. Gated communities with homes lining the edges of golf courses became a popular commodity. Mostly on the northern side of Tahquitz Creek, these communities skewed more towards traditional Spanish Revival styles and slightly smaller lots. Within a amount of time, Palm Desert had developed a wide array of lifestyles, architectural character, and community patterns. An early Palm Village advertisement promoted convenient recreational opportunities. The gated golf course community model, although inclusive, provides few connections to other neighborhoods. A-94 | 01.07.17 | CITY OF PALM DESERT UNIVERSITY NEIGHBORHOOD SPECIFIC PLAN SECTION A.7 | ARCHITECTURAL GUIDELINES 3. Landscape Traditions The other main component of Palm Desert's heritage is its physical landscape. The area's arid climate and wide, flat expanses were inviting to developers, vaca- tioners, and cultivators for many reasons. In the 1950's, as citrus groves in Los Angeles began to be subdivided and developed, the Coachella Valley offered a blank slate for date palm and citrus growers. Mass-market developers also saw a blank canvas in the desert, as there were no geographic constraints besides the mountains to hinder them. To the vacationer, the flat Highway 111 and Palm Springs Airport provided an easy way to get in and get out of town. During the initial development boom, the Valley floor' environmental landscape was not much more than small boulders, sand, and native bushes and trees. Architecture, for the most part, would have to help mitigate the desert heat. Thin, long floor plans, courtyards, and low building masses helped to offset some of the heat effects, but landscape would serve an equally important role. When the area was first developed, native plants were few and far between. Early housing developments would bring with them patches of non-native green grass from the Los Angeles area, with little regard for the low amount of rainfall in the area. Date palms and other desert plants were brought in from all over the world to diversify both the agricultural landscape and neighborhood landscape. Many of these plants are successfully adapted to the desert, and, although non-native, are well-suited for the unique climate of the area. Today, the image of the pool in the backyard of a Mid-Century house, or palms set against the light plaster walls of Spanish Revival building are iconic visuals in Palm Desert and the Coachella Valley. In recent years, with the prospect of more stringent water resources and warmer temperatures, many communities have moved towards emphasizing drought-tolerant plants and landscapes. Many front yards have done away with green grass in favor of exposing the original sandy, rocky landscape while adding succulents and other desert plants. An early photo of El Paseo shows the scarcity of native plant life A Mid-Century house with a beautiful landscape made of mostly adaptive plants CITY OF PALM DESERT UNIVERSITY NEIGHBORHOOD SPECIFIC PLAN | 01.07.17 | A-95 DESIGN GUIDELINES | APPENDIX A B. Building Architecture and Form 1. General These Guidelines provide direction for the design of buildings, appurtenances and site elements within the UNSP area. Photographs and diagrams provided in this section illustrate recommended options for the massing and architecture of the buildings in the subject area. 2. Relationship to Development Guidelines The Development Guidelines in Section 4.4 define the location and massing of buildings and site elements on the project sites, focusing on the relationship of the building to the project site, the block and the neighborhood. These Architectural Guidelines define the recommended range of design and performance possibilities in order to achieve a degree of authentic- ity and cohesion for the physical character and quality of the area. These Guidelines are to be applied in concert with the building typologies defined in the Development Guidelines (Appendix A.2 and A.4). By carefully applying these guidelines to the recom- mended Building Types (Appendix A.2 and A.4), the skilled architect will be able to design a wide range of buildings, for a wide range of uses, household types and constructions budgets. 3. Design Intent While no specific architectural styles are required, four Architectural Styles (Appendix A.7.C) are identified as particularly relevant to the heritage and character of Palm Desert and the Coachella Valley, and are used to help illustrate recommending design approaches. 4. Materials in General Authentic, natural building materials are recommend- ed, including smooth plaster, fine concrete block, brick, stone, tile, wood, terra cotta ties and appropriate metals. Such materials age gracefully, while many synthetic materials do not. Synthetic materials that simulate natural materials may be allowed, when approved in writing by the Director and based upon the findings. a. That the material faithfully simulates the appearance of the natural material it imitates; and, b. That the material has a demonstrated ability to weather gracefully, aging similarly to or better than the natural material it simulates A new multi-family residential building designed as simple assemblies of house-scale forms.

Recommended treatments include: Special paving materials such as ceramic tile; Ornamental ceilings such as coffering; Decorative light fixtures. v. Vines grown in vine pockets or planter boxes at the building facade are allowed within the setback. b. Configurations i. A cornice or horizontal band should be provided to differentiate the Shopfront from upper levels of the building. This also allows the storefront to function as the visual base for the rest of the building. In some instances where storefronts include entablature trim, the horizontal band may be omitted. ii. Modern buildings may use bi-fold or sectional garage door systems within storefronts iii. Awnings and shed roofs may be incorporated in the Shopfront above entries or storefront assemblies, but should not run continuously across from opening to opening across the entire shopfront. iv. Lighting should be mounted on the storefront wall, preferably centered on the piers between windows/ doors or centered above the windows/doors of the shopfront. In instances where projected shed roofs are used over entries the lighting may be mounted in the underside of the shed element. Traditional Storefront A Header should either be four or five brick courses high, and project out at least one inch from face of the building.

Coordinated and subdued colors typical of natural building materials, such as earth tone colors are recommended. Extremely bright colors are not recommended except on doors, window trim, or other building components that represent a small portion of the overall building facade. b. White and lighter earth tone colors are encouraged as ways of reducing heat gain on buildings and project a classic Coachella Valley architectural character. c. The number of exterior facade colors should be limited to two or three. A base color and a coordinating secondary color for trims and accents. Additional complementary colors should be used sparingly and to accent particularly beautiful building elements. d. Allowing the natural color of materials such as stone or brick to dominate the majority of facade surface as its base color is recommended. Exceptions can be made for modern buildings. e. Trim and accent secondary colors for elements such pilasters, horizontal bands, cornices and window frames should complement the shade of the base color. Deep recessed, double door entry with side hinged doors 13. Vents, Grilles, Caps a. Vents should not be visible from the street or from shared open spaces such as courtyards or forecourts. b. Materials of vent grilles or caps should be consistent with the overall style and character of a proposed building and should be coordinated with the building’s finishes and architectural details. 14. Service and Utility Placement a. Service Areas. i. For lots with alley access, service entrances, waste disposal areas, and other similar service areas should be located adjacent to the alley and take their access from it. ii. When an alley is not present, service entrances, waste disposal areas, and other similar service areas should be located as far away from – and screened from views from – the Primary and Secondary streets as practical.

Architectural Styles of Palm Desert 1. Definition of Style Within the Architectural Guidelines, the word "style" is used to denote the overall character of a building brought about through the combination of massing, ornament, and materials. A truly authentic building within a style is one that uses all of these elements appropriately in conjunction with one another. These principles can be applied to both House Form and Block Form building types. "Traditional buildings" as referred to within the doc- ument are those that combine traditional massing with traditional ornament and materials. "Modern buildings" are those that incorporate either modern details, modern massing, or both. For example, a Palm Desert Ranch building is considered modern because, although the windows and doors are often traditional, the monolithic roofs and sprawling horizontal facades are considered modern massing elements. Buildings with traditional window sizes and spacing can still be considered modern if the windows are articulated with modern materials such as steel, or built into walls made of modern materials. Many of the hallmark Mid-Century build- ings within the Coachella Valley are the product of pairing modern materials with modern massing. To design within a style is not to directly mimic a previous building or group of buildings brick by brick, but rather to build on trends and traditions attributed to a style. Styles themselves are living traditions with great flexibility, and sometimes are not precisely delineated in the built environ- ment.

Local Building Tradition The following pages are intended to illustrate designs characteristic of the Coachella Valley variants of four broad American Styles. These illustrations convey the level of detail that is to be provided in the architecture of the buildings, but certainly do not include of all possible variations. Palm Desert and the Coachella Valley have a rich tradi- tion of being habitats for both subtle traditional styles and avant-garde modern styles. Although many of these styles are ubiquitous in California, local communities have adopted variations of styles that are specifically tailored to local climate, geography, and lifestyle. Desert heat has, over the years, resulted in Spanish Revival buildings with more intimate shaded courts and heavily shaded balconies. Ranch and Mid-Century buildings incorporate deep shade recesses and low, moderate - ly-overhanging roof forms. Roof forms are often a good indicator of a building's style because they reveal which structural system is being uti- lized. Steel systems allow modern buildings to incorporate innovative monopitch roof forms, and, traditionally, heavy timber and masonry encouraged shallow-pitched roofs with relatively short spans in Spanish Revival buildings. A-122 | 01.07.17 | CITY OF PALM DESERT UNIVERSITY NEIGHBORHOOD SPECIFIC PLAN SECTION A.7 | ARCHITECTURAL GUIDELINES Spanish Revival buildings with multiple units usually contain intimate shaded courts such as these. 3. Spanish Revival a. Description The Spanish Revival Style is a hallmark California archi- tectural language with many different variations and configurations. The early Spanish missions founded established throughout the state helped to inspire the first wave of residential and commercial structures in the style, while the 1915 Panama-California Exposition helped to introduce certain Baroque elements and more Spanish elaborations to the style. The resulting style is one that is fundamentally simple, with small occurrences of architectural flourishes such as wrought iron railings and decorative tiles. The style is particularly well suited to desert climates because of the heavy use of white plaster walls that help reduce heat gain, along with covered porches and balco- nies to provide shaded outdoor spaces.

Palm Desert Ranch a. Description A style with roots back to the post-WWII era, the ranch style is the result of the modern revolution in manufac- turing domestic house products. Along with manufac- tured windows and doors, the style includes roof forms easy to construct from widely produced trusses and other components. Although the style is now ubiquitous throughout the country, neighborhoods in Palm Desert and the Coach- ella Valley have adapted the style to the local context, making it a part of the local vernacular. The Palm Desert Ranch style borrows certain elements from the Mid-Cen- tury modern style, such as the use of uninterrupted masonry walls, but also includes its own characteristics such as L-shaped plans. This style is only applied to single family detached house types. B C G A DF A CITY OF PALM DESERT UNIVERSITY NEIGHBORHOOD SPECIFIC PLAN | 01.07.17 | A-125 DESIGN GUIDELINES | APPENDIX A b.

A mixture of Japanese and West Coast post-and-beam buildings with the Contemporary style propagated by Mies Van der Rohe and Walter Gropius, mid-century ar- chitecture strives to create an efficient house form with certain custom crafted elements. In California specifically, Mid-Century homes, such as those widely built by Joseph Eichler, tend to be spread over the majority of the lots they are on, and incorporate outdoor spaces such as courtyards and carports into the Primary Mass of the building. Local desert stones are often incorporated into walls along the front facade, and clerestory windows allow for well lit interiors.

A direct result of the Bauhaus movement, the Contem- porary style now includes many different variations of house designs that all share the same general principles. Most contemporary houses use large amounts of glazing with industrial materials such as metal sidings and posts. Locally, the Contemporary style has used glass facade portions to capitalize on panoramic desert views. Large overhanging mass forms often create large shaded porch and balcony areas.

Style Mismatched Style and Roof Massing. In Spanish Revival architecture, the roof’s mass matches its origins in Spain. the dry climate and rarity of tall trees (for beams) produced a simple, single form, medium pitched roof with baked earth tiles, all sitting on and reinforcing the simple mass of stone walls below. Aberrations today include irrational complex roof forms, cartoon-like steeply-pitched roofs, and oversized roof tiles. The business of such roofs is out of character with the understated elegance of Palm Desert - their exaggerated verticality is in direct conflict with the horizontal proportions of their ascribed architectural character. Mismatch of Style and Massing. Within traditional buildings, openings should be as regular as the room layouts within. Historically, the room sizes were based on the limits of masonry walls. Aberrations of today arise when complex masses are added in random shapes and patterns that would never and could never have been built of stone, undermining the authenticity of the traditional styles. D. Architectural Aberrations An example of massing that does not relate well to modest room sizes. A complex, convoluted roof form on a smaller, simpler home. An abundance of ornament and applications of the same material in different circumstances cause visual confusion. AV O I D AV O I D AV O I D CITY OF PALM DESERT UNIVERSITY NEIGHBORHOOD SPECIFIC PLAN | 01.07.17 | A-131 DESIGN GUIDELINES | APPENDIX A Misuse of Detail and Materials. This includes non- functional, decorative, or surplus details which yield an ornamental pastiche. Original (precedent) buildings used restraint on details, the majority of which were present for building protection (functional), and the minority there for embellishment at key parts of a façade. In contrast, today’s aberrations treat details as a fancy wallpaper stretched around a bloated mass. Materials misuse aberrations occur when synthetic materials are dominant on a façade, or where they are applied in a non-traditional manner (such as a brick wall on a 2nd floor over a stucco 1st floor). Multi-Styled Buildings. When designing ones' dream home, the impulse to include “all your favorite things” is understandable, but can lead a client, designer or builder to combine a potpourri of architectural styles and ideas on the exterior of the house. This is inconsistent with the understated elegance of Palm Desert, which requires editing and an eye for style. A good rule for all Palm Desert homes is “one style per house”. This house combines many different building traditions to create a confusing, chaotic building. This house incorporates synthetic materials abundantly and unnecessarily. This house has no apparent Primary Mass, and a confusing mismatch of style and massing. AV O I D AV O I D AV O I D A-132 | 01.07.17 | CITY OF PALM DESERT UNIVERSITY NEIGHBORHOOD SPECIFIC PLAN SECTION A.7 | ARCHITECTURAL GUIDELINES 2. Massing Absence of Primary Mass. The first common aberration is the absence of a clear Primary Mass, which makes up the main body of a house. This body should be dominant and legible, and is defined by a basic rectangular shape which is articulated by an associated singular roof form of concomitant simplicity. In the aberrational examples, this main body is not legible; either because the house wings dominate the massing or because the applied roof forms obscure and confuse the main house. Blocky Massing. The second aberration is blocky massing, usually in the form of a large square plan. A house of this size is achieved, from the onset of design, by enlarging the scale of public rooms (living, dining, central staircase,etc.) and attaching rooms thereto, all for the sake of ‘flow of space’. The center portion of the house is 3 or 4 rooms deep from the exterior, with no view, no natural light, no air. In Palm Desert and other classic communities, houses are typically composed of rectangular volumes joined in asymmetrical or symmetrical assemblies. The public parts of the house are contained within the largest rectangular mass, and private parts (bedrooms, bathrooms, studies) are located on the upper floors of the Primary Mass, or are appended in separate rectangular volumes. The rectangular proportion is essential, for it speaks to residential-scale structural capabilities, human- scaled rooms, and rooms with access to views and air. Complex Massing. The third increasingly common aberration is complex massing, in which individual room volumes within a house are expressed in plan, massing, and roof form, undisciplined by the rigor of the recommended Primary Mass and wing organization. The end result of such complicated massing is not a cohesive elegant design, but rather an apparent collection of disparate parts. Like the other aberrations, this technique is used frequently in an attempt to disguise a house mass that is too large for its lot or its neighborhood. The phrase “breaking up the mass” frequently accompanies this technique, which is not appropriate to Palm Desert. Massing in Palm Desert is intentional, not mitigation of bad decisions made in plan.

Sign Design The following design criteria should be used in reviewing the design of individual signs. Substan- tial conformance with each of the following design criteria is required before a sign or building permit can be approved. 1. General a. In order to avoid sign clutter, signage should only be allowed on facades that have building entrances. b. Signs should not cover or obscure windows, doors, storefronts, building entrances, cornices, columns, or other architectural elements or details. c. The gross area of all signs that are mounted parallel to a façade should not exceed 10% of the total area of the façade. Ground floor business within a building may have one or multiple storefront signs. Storefront signs should be placed in an area that is above the ground floor storefront windows and below the windows on the second floor. 2. Color Colors on signs and structural members should be harmonious with one another and relate to the dominant colors of the buildings on the project site. Contrasting colors can be utilized if the overall effect of the sign is still compatible with building colors. 3. Design and Construction a. Except for banners, flags, temporary signs, and temporary window signs conforming with the requirements of this section, each sign should be constructed of permanent materials and should be permanently attached to the ground, a building, or another structure by direct attachment to a rigid wall, frame, or structure. b. Each permanent sign should be designed by a professional (e.g., architect, building designer, landscape architect, interior designer, or others whose principal business is the design, manufacture, or sale of signs), or who are capable of producing professional results. c. Each permanent sign should be constructed by persons whose principal business is building construction or a related trade including sign manufacturing and installation, or others capable of producing professional results. The intent is to ensure public safety, achieve signs of careful construction, neat and readable copy, and durability, to reduce maintenance costs, and prevent dilapidation. Example of sidewalk signs Examples of window signs CITY OF PALM DESERT UNIVERSITY NEIGHBORHOOD SPECIFIC PLAN | 01.07.17 | A-135 DESIGN GUIDELINES | APPENDIX A 4. Materials and Structure. a. Sign materials (including framing and supports) should be representative of the type and scale of materials used on the project site where the sign is located. Sign materials should match those used on the building(s) on the project site and any other signs on the project site. b. Signs should not include reflective material. c. Materials for permanent signs should be durable and capable of withstanding weathering over the life of the sign with reasonable maintenance. d. The size of the structural members (e.g. columns, crossbeams, and braces) should be in proportion with the sign panel they are supporting. e. The use of individual letters incorporated into the building facade design is encouraged, rather than a sign with background and framing other than the structure wall. 5. Street Address. The City may require that a sign include the street address of the project site, where it determines that public safety and emergency vehicle response would be more effectively served than if the street address were displayed solely on one or more buildings on the project site. 6. Copy Design Guidelines. The City does not regulate the message content (copy) of signs; however, the following are principles of copy design and layout that can enhance the readability and attractiveness of signs. Copy design and layout consistent with these principles is encour- aged,but not required. a. Sign copy should relate only to the name and/or nature of the business or commercial center. b. Permanent signs that advertise continuous sales, special prices, or include phone numbers are only permitted as window signage. c. Information should be conveyed briefly or by logo, symbol, or other graphic manner. The intent should be to increase the readability of the sign and thereby enhance the identity of the business. d. The area of letters or symbols should not exceed 40% of the background area in commercial districts or 60% in residential districts. e. Freestanding signs should contain the street address of the parcel or the range of addresses for a multi-tenant building. Wall mounted sign Projecting signs. A-136 | 01.07.17 | CITY OF PALM DESERT UNIVERSITY NEIGHBORHOOD SPECIFIC PLAN SECTION A.8 | SIGNAGE GUIDELINES 7. Sign Lighting. Sign lighting should be designed to minimize light and glare on surrounding rights-of way and properties. a. External light sources should be directed and shielded so that they do not produce glare off the project site, on any object other than the sign. b. Sign lighting should not blink, flash, flutter, or perceptibly change light intensity, brightness, or color. c. Colored lights should not be used at a location or in a manner so as to be confused or construed as traffic control devices. d. Neither the direct nor reflected light from primary light sources should create hazards for pedestrians or operators of motor vehicles. e. For energy conservation, light sources should be hard-wired fluorescent or compact fluorescent lamps, or other lighting technology that is of equal or greater energy efficiency. Incandescent lamps are prohibited. f. Internally illuminated box signs that light the entire sign (letters, symbols, logos and background) are prohibited. 8. Directory Signs. Directory signs are small wall signs located at pedestri- an eye level and intended to identify multiple tenants within a building or complex. The following guide- lines apply to these signs. a. When tenants are accessed via a building lobby or outdoor court, directory sign must be located within the lobby or court. Directory signs on street facades may be approved by the Director upon a finding of special circumstances. b. Directory signs should not exceed 6 square feet. c. Directory signs should be externally illuminated. Internal illumination and neon lighting is prohibited.

Landscape Strategies The following specific landscape design strategies will inform the final design of the UNSP area: a. Utilize a mix of vertical trees (primarily palms of various varieties) to define the primary framework streets and entry points of the neighborhoods, and deciduous canopy trees to provide shade along the sidewalks and within the parks, greens and squares of the neighborhoods and centers. b. Utilize appropriate street and park trees that tolerate stress, provide summer shade and winter sun, and provide a variety of texture and color characteristics; c. Provide landscapes compatible with an arid environment and use a palette of native and drought tolerant plant species conducive to eco- friendly pesticides and compatible with the natural vegetation of the area; d. Generally reserve maintained turf for active recreation and play areas, employing more drought tolerant plant materials and hardscapes and rockscapes elsewhere. e. Design the street and open space network as a system for sustainably managing the flows and environmental quality of precious stormwater, including opportunities to store and reuse stormwater for landscape irrigation. f. Utilize landscaping to screen unattractive areas abutting the UNSP area. Succulents and desert-friendly grasses can be distributed in creative ways in public spaces. Front yards can employ a wide range of plant sizes, colors, and forms within a drought-tolerant landscape. In a climate with strong direct sunlight, shade and canopy trees can help encourage pedestrian activity. B.1 General Landscape Guidelines CITY OF PALM DESERT UNIVERSITY NEIGHBORHOOD SPECIFIC PLAN | 01.07.17 | B-3 LANDSCAPE GUIDELINES | APPENDIX B Green environments help to cool local environs and reduce pollution. Desert parks and gardens help preserve the natural environment, and encourage walking, even in a hot climate. Trees can be used to both provide shade for sidewalks and screen unattractive expanses of walls or service areas. 2. Landscape Sustainability Site planning and landscape design within the UNSP should promote conservation, preservation and the en- hancement of the natural environment that is balanced with sensitivity to long-term environmental and fiscal sustainability. The UNSP area has also been planned and designed to integrate practices of sustainable stormwater manage- ment known as “Low Impact Development (LID)”, an approach to land development that works with nature to manage stormwater as close to its source as possible. Mandated by City policy - and unlike a conventional system that would simply pipe uncleansed stormwater into drainage channels - the stormwater systems of the UNSP will instead employ a multi-layered LID system of distributed BMP measures to collect, infiltrate and cleanse rainwater as close to the source as feasible. This system includes: a. Measures on individual lots, which may include flow-through planters, rain gardens, cistern, and biofiltration basins and vegetated swales; b. Measures along the UNSP streets, alleys and parking lots such as biofiltration basins and vegetated swales, permeable alleys, parking lanes, sidewalks and parking lots; and filtration and infiltration areas in the parks and greenways. c. In the Neighborhood Center zone storm drain filters (Filterra, Vortechs, or equivalent units) should be proposed due to design characteristics that are ideal for urban settings: they are extremely space efficient, have a minimal impact on site utilization. B-4 | 01.07.17 | CITY OF PALM DESERT UNIVERSITY NEIGHBORHOOD SPECIFIC PLAN SECTION B.1 | GENERAL LANDSCAPE GUIDELINES Parking with permeable pavers and rainwater collecting planters Stormwater detention areas help manage runoff from rain events. Storm drain filter systems help to naturally filter runoff . Cisterns can be used to store rainwater. They may either be above ground tanks or integrated into the landscape. 3. Water Conservation The UNSP area should utilize progressive techniques in water conservation technology and practices through careful planning and thoughtful design and engineering. The UNSP area, following LID practices, should minimize stormwater flows by promoting on- site infiltration and reducing contaminants through biological filtration. The objective is to decrease runoff peak flow and volume by providing many opportunities for water retention and on-site infiltration. As a result the rate and volume of on-site stormwater infiltration will be increased, achieving on-site water cleansing and filtration, and a significant reduction in stormwater flows. Innovative stormwater management features and filtering systems for reducing pollutant loads should be integrated into the project, such as biologically based systems and associated bio-retention areas, bioswales and vegetated filter strips. In the Neighborhood Center storm drain filters (Filterra, Vortechs or equivalent units) should be installed to remove debris and hydrocarbons prior to discharge. CITY OF PALM DESERT UNIVERSITY NEIGHBORHOOD SPECIFIC PLAN | 01.07.17 | B-5 LANDSCAPE GUIDELINES | APPENDIX B 4. Biofiltration & Stormwater Management The UNSP streets are part of a visible system of the green infrastructure’ that encompasses pedestrian, bicycle and auto circulation, and community open spaces that provide for various recreational needs, yet act as a functional system for stormwater treatment and management. Street design also incorporates the stormwater system into the aesthetics of the community and encourages community education and responsibility. a. Parkways and Planters i. Planters and Tree Grates: Planters are typically provided on urban and/or commercial streets, where wide sidewalk space is desirable. Planters should have a minimum dimension of 4'x4', and may be grated to provide additional continuous sidewalk space. ii. Continuous Parkway/Planter: Typically applied to neighborhood streets, parkways are landscaped areas that buffer the sidewalk from the street, and may accommodate in addition to street trees, a variety of landscape elements. Drought-tolerant alternatives to traditional turf landscaping are encouraged in drought- sensitive climates. iii. Rain Garden with Curb-cuts: Where possible, drainage channels may be cut into street curb face to allow street run-off wastewater to flow into streetside gardens, providing biofiltration, and slowing runoff into the sewer systems. iv. Flex Planter: Parkways fronting work/live, retail or commercial uses may be hardscaped to provide additional sidewalk width for a variety of approved uses. Parkways may be landscaped in a variety of ways, and turf-alternatives, such as decomposed granite, mulch, and hardscape, are recommended for drought-sensitive areas. For streets lined with a mixture of office, retail, and residential parkways may be filled in with permeable pavers to increase the usable sidewalk space. A green street with curbless planter areas B-6 | 01.07.17 | CITY OF PALM DESERT UNIVERSITY NEIGHBORHOOD SPECIFIC PLAN SECTION B.1 | GENERAL LANDSCAPE GUIDELINES b. Medians & Swales i. Medians: On streets with large rights-of-way, center medians may be provided to additionally enhance the landscape character of the street, accommodate left-turn pockets, and provide pedestrian refuges in crosswalks at intersection and mid-block crossings. Medians may be designed and landscaped in a variety of ways, including rain gardens, bioswales, hardscape, turf, and/or street trees. Where possible, medians should be wide enough to accommodate left-turn pockets, and should provide pedestrian refuges at intersections and mid-block crossings. ii. Rain Gardens and Bioswales: On streets with rolled- curbs, no curbs, or drainage channels cut into the street curbface, bioswales, rain gardens, and ditches may take the place of a traditional raised parkway, providing biofiltration of street water runoff. Drainage channels may be cut into street curbface to allow street run-off water to drain into medians, providing biofiltration and wastewater management.

Parking Lanes i. Parking Lane Planters: Parking lane planters accommodate street trees on streets with existing sidewalks that are either directly adjacent the street curb, or are too narrow to accommodate planters or parkways. They additionally can visually narrow wide streets and calm traffic. Planters are spaced away from the street, so that drainage gutters are unimpeded, and may additionally, be "open-backed" - allowing street water runoff to seep into planters. In more urban settings, bulb-out planters may be grated to reduce maintenance of planter landscaping. ii. Permeable Pavements: Where possible, parking lanes should employ permeable pavements that both contrast the main street material to denote parking and allow for infiltration. Using permeable pavements in conjunction with appropriate planters allows for a wide range of infiltration opportunities. Materials for permeable areas include spaced concrete pavers and decomposed granite. The permeable pavement areas should be located adjacent planter bioswales and infiltration areas when possible. Permeable pavers within a parking area In-street planter bulb-outs Permeable materials such as pavers, decomposed granite, or gravel can be applied to parking lanes in a variety of settings. Corner bulb-out planter with street drainage maintained B-8 | 01.07.17 | CITY OF PALM DESERT UNIVERSITY NEIGHBORHOOD SPECIFIC PLAN SECTION B.1 | GENERAL LANDSCAPE GUIDELINES 5. Permeable Pavements Permeable pavements are load-bearing surfaces that have the capability of infiltrating runoff into the under- lying reservoir base coarse (with at least 40% void space) and soil. Different types of permeable pavement include: a. Porous asphalt that is comprised almost entirely of stone aggregate and asphalt binder with very little fine aggregate; b. Pervious concrete that has a permeability rate of 12 inches per hour and has the appearance of exposed aggregate concrete; c. Unit pavers, bricks or stones that provide a durable and attractive surface, spaced to expose a permeable joint and placed on a permeable base; d. Crushed aggregate that provides a wide variety of aggregate types, and which must be bounded by a rigid edge; e. Turf blocks; f. Cobbles which are suited for low traffic areas and require a rigid edge. When possible, surface parking areas should be con- structed of pervious paving material to achieve filtration and partial storage during storm cycles except those greater than ten year storm events. Permeable concrete, grasscrete, and other pervious paving systems are ac- ceptable. Surface overflow should drain to biofiltration strips through curb cuts. Properties that have podium or subterranean parking should provide a cistern to collect run-off during rain events. They may be placed any- where on the property or integrated as part of the struc- ture. Overflow should drain to the water quality features prior to discharge into nearby drainage channels. Spaced concrete pads with ample amounts of permeable material in between can be used for areas with light vehicle traffic. Permeable pavers with alternate colors are used to denote parking space lines. A desert environment is one in which native plants are able to grow directly in a permeable pavements that drain well. CITY OF PALM DESERT UNIVERSITY NEIGHBORHOOD SPECIFIC PLAN | 01.07.17 | B-9 LANDSCAPE GUIDELINES | APPENDIX B 6. Street and Open Space Lighting Streets and other public spaces throughout the UNSP area must be carefully scaled and detailed for the safety and comfort of pedestrians. For the UNSP, very simple, light-scale, modern fixtures with high efficiency LED sources and down-directed “dark sky” cutoff distribution patterns. a. On major streets, existing cobra-head lights will remain, with new lights illustrated here located between them at approximately 60 feet on center. This is about twice the tree spacing, located at the midpoints between trees. b. On neighborhood streets, lights should be located mid-point between every fourth tree (120 ft.), staggered in such a way that there is one light every 60 linear feet of street, alternatively on one side or the other, not both. c. Along streets fronting a park or greenway, single- head lights must be located along the built edge of the street at about 90’ on center (at about every third tree), unless specified otherwise. d. Any lights in park areas should be integral to the park design. This simple post-top luminaire is recommended for most streets, with high efficiency LED lamps and excellent “dark sky” downward directed light distribution. Modern columnar luminaires are well suited to lighting neighborhood center plazas and paseos. Along park drives at neighborhood edges, taller modern LED luminaires can better define large open spaces. This indirect LED post-top luminaires may be suitable for smaller neighborhood streets and for parks and public spaces throught the UNSP. B-10 | 01.07.17 | CITY OF PALM DESERT UNIVERSITY NEIGHBORHOOD SPECIFIC PLAN SECTION B.1 | GENERAL LANDSCAPE GUIDELINES 7. Street and Open Space Furnishings Street furnishings will contribute to the comfort and human scale of the public spaces throughout the UNSP, particularly in the neighborhood centers, plaza, parks and greens. Wherever possible, furniture that can be relocated within a seating area is recommended, to provide flexibility and a sense of ownership of the space by residents and others. Parallel to the recommendations for simple, modern light fixtures, furnishings should be of a simple, clean, modern design. This furthers a central objective of the UNSP urban design, that it build on Palm Desert’s design heritage of modernity, moving forward from the mid-twentieth century modern toward a new 21st century modern, human-scale neighborhood aesthet- ic rather than nostalgia for the 20th or 19th century precedents on which much of the UNSP neighborhood pattern language is based. Light scale modern furniture can be secured or movable within a seating area and project a simple, clean aesthetic. Synthetic wood slats remain comfortable even in the summer sun. Bike racks should be simple, clean and fiunctional.Trash receptables and other functional elements should coordinate with seating.

B. Parks, Plazas, Squares and Greens 1. General Guidelines A network of plazas, squares and greens has been designed to provide residents with a variety of outdoor experiences. Plazas are highly ordered spaces, usually with a cluster of buildings that tightly define exterior space. Squares are green areas often placed in front of or closely aligned with civic buildings that help define their stature within the community. Greens provide play space to recreate and commune with nature. Although the character of public space differs, and hence the human experience, they all form the community’s backyard and offer opportunities to spend time in the company of others or to find solitude. 2. Recommended Plant Materials The design of these "community living rooms" should emphasize comfort and flexible use - accordingly shade trees, shaded seating areas and a variety of ground surfaces for walking and play are recommended. For specific plant material recommendations see the Recommended Tree and Plant Lists at the end of this Section and the more complete plant list in Appendix A. Outdoor event areas should integrate desert landscape and hardscape elements. B-12 | 01.07.17 | CITY OF PALM DESERT UNIVERSITY NEIGHBORHOOD SPECIFIC PLAN SECTION B.1 | GENERAL LANDSCAPE GUIDELINES 1. Description A University Mall is a larger connected open space, typically serving as the central spine of pedestrian connectivity on a university campus. The University Mall informs building design, scaling and massing of the overall site. 2. Context and Connectivity Positioned as the central pedestrian space of the future uni- versity campus, all major pedestrian routes should lead to and connect with the Mall. Vehicular routes may also cross through the Mall at intermittent locations, but vehicular ac- tivity should be limited to increase safety and the preserve the space as a pedestrian environment. 3. Function and Design Opportunities The University Mall should be framed by university build- ings with frontages and sidewalks that directly enter the Mall. At the ends or “head” of the Mall’s axis, the university should prioritize iconic buildings that serve as the civic center of the campus. These iconic buildings should have more significant scales, massing and architecture styles that define their role and prominence on the Mall. The Mall itself will serve the following functions: a. Provide the primary pedestrian routes and passive recreational use through the campus. b. Create gathering spaces and special event areas able to host university and community-based festivals. c. Establish the mall as the central unifying element for the university campus. 4. Landscape The goal of landscaping within the University Mall is to en- hance visibility of the entire length of the Mall and provide key focal points to the buildings that frame it. In the regard, landscape guidelines include the following: a. Large unobstructed lawns and pathways should dominate the center of the Mall. b. Trees and plants should be arranged at varying intervals along the side in order to provide shade throughout the Mall and frame the edges. Variability in tree species, size and spacing is recommended to create a more natural-looking space. c. Hardscape pathways and pavers should cross the Mall to create key linkages between buildings and support convenient natural pedestrian routes. C. University Mall 400’ SCALE A University Mall creates a series of interconnected open and hardscape spaces through the center of campus. CITY OF PALM DESERT UNIVERSITY NEIGHBORHOOD SPECIFIC PLAN | 01.07.17 | B-13 LANDSCAPE GUIDELINES | APPENDIX B 5. Design Details and Elements a. Size. University Malls should be long and narrow in form, but they may vary from ±75-200 feet wide as long as they complement the scale of the surrounding environment. b. Visibility. Malls do not require direct visibility from vehicular streets, but a combination of design and wayfinding strategies will easily lead pedestrians to the Mall. Viewsheds within the Mall should be maintained to all surrounding buildings and both ends of the Mall. c. Frontages and Adjacencies. University buildings will provide the majority of frontages along the Mall. Plazas and/or iconic buildings should be place at both ends of the Mall. d. Shading and Lighting. Traditionally, Malls do not have shade structures or trees to preserve an open green; however, the use of side courts, tree-lined walkways and occasional tree planters can provide shade across the Mall without obstructing visibility. e. Structures and Improvements. Small side courts, rest areas and pedestrian amenities (benches, picnic tables, etc.), should be located throughout the Mall; however, pedestrian circulation should be prioritized. Shade trees and canopies may be used to create comfortable spaces on a long University Mall. Small plazas and seating areas provide shaded intimate spaces with the University Mall. University Mall with centralized hardscaping and landscaping Typical open greens within a University Mall B-14 | 01.07.17 | CITY OF PALM DESERT UNIVERSITY NEIGHBORHOOD SPECIFIC PLAN SECTION B.1 | GENERAL LANDSCAPE GUIDELINES Building shade paired with greenery helps to dramatically cool an area. Front yards may either take on a more natural, rugged landscape appearance or a more minimal, formal appearance. Succulents and other desert plants can be potted or planted in yard areas. D. Private Lot Landscape Guidelines 1. General Guidelines Each lot should provide landscaped and permanently pervious open space as required for the applicable building type. See Appendix A.6 On-Site Open Space Standards. 2. Front Yard Landscapes Plantings in yard areas fronting on streets should be appropriate to the scale, orientation and purpose of the yard. Appropriate plant materials and designs for specific frontage yard types are as follows: a. Single-family front yards. At facades, foundation shrubs and ground cover should be planted against the facade. At garden walls, low shrubs and wall vines or tall shrubs should be planted against the wall. b. Multi-dwelling front yards. Lawn, ground cover and low shrubs should compose the front yard landscape. Shrubs should be massed or configured as maintained hedges. Hardscape may be used adjacent to entrances and in seating areas. Tree shapes, sizes and types should be planted at the edge of the private space, but at all times should be in proportion to the height and mass of the building facade. 3. Other Yard Landscapes Side and rear yard plantings should be planted to insure privacy and create buffers. Rear yards and property lines do not need to be landscaped, except as required to the extent that they affect the quality of the public space. 4. Recommended Plant Materials See the Recommended Plant List at the end of this Section and Appendix A. CITY OF PALM DESERT UNIVERSITY NEIGHBORHOOD SPECIFIC PLAN | 01.07.17 | B-15 LANDSCAPE GUIDELINES | APPENDIX B Backyards with pools should minimize lawn areas, while also incorporating drought tolerant landscape areas. A yard with flagstone pavers and fountain Sideyards can incorporate planters, pots, and landscaped areas. B-16 | 01.07.17 | CITY OF PALM DESERT UNIVERSITY NEIGHBORHOOD SPECIFIC PLAN SECTION B.1 | GENERAL LANDSCAPE GUIDELINES Colorful desert landscapes with native, drought-tolerant plants and permeable ground cover materials. Drip irrigation can provide a specific amount of water directly to the base of a plant, avoiding watering unplanted areas. A landscape with native and adapted drought-tolerant plants will require little irrigation. 5. Irrigation Water efficient landscaping should be introduced, beginning with a soil and climate analysis to determine the most appropriate landscape design, including the selection of indigenous and native-in-character, drought tolerant plants to reduce irrigation requirements. Lawn should be restricted to particular areas of passive and active recreation. Wherever lawn is used the select- ed species should be a deep-rooted variety with low watering requirements. Where irrigation is required, high efficiency irrigation technology with low pressure applications such as drip, soaker hose, systems with rain shut-off devices and low volume spray systems should be used. The efficiency and uniformity of a low water flow rate reduces evaporation and runoff and encourag- es deep percolation. After the initial growth period of 3 to 7 years, irrigation should be limited.

Installation of a desert detention area Rain chains help to divert and store rainwater from gutters An appropriately landscaped rainwater garden in a desert climate 6. Stormwater Management Runoff from buildings should be reduced through the reduction in the overall building footprint. Roof runoff can be collected and diverted to underground drywells where water can slowly infiltrate. Drywells are sloped and located at a distance from the building foundations. Alternatively, buildings can be designed with rain-chains, stone streambeds and stone filters, porous pavers and rainwater gardens adjacent to the side of the building. Roof runoff is collected into gutters, which direct water down the rain-chains, and into rock filters. Rock filters and ephemeral graded stone streambeds further direct stormwater into the rainwater gardens. The rainwater gardens are landscaped depressions, where roof runoff and ground surface runoff is directed, through grading, into the depression. These gardens filter, absorb and treat stormwater on site, provide visual identification, and promote education of residents through “celebra- tion” of stormwater management.
