191114 Section 33.0 DESIGN GUIDELINES TRAVERTINE SPECIFIC PLAN AMENDMENT – 2019 Page 3-1 DESIGN GUIDELINES The guidelines contained in this section identify unifying elements for design of buildings and landscaping within the Travertine development in order to compliments its surrounding community. The exhibits provided are intended as conceptual illustrations and do not depict final designs, or plans. 3.1 Purpose and Intent The Design Guidelines have been developed to achieve a high quality, cohesive design concept for the community that will develop within the Travertine Specific Plan. These design guidelines provide the foundation for the design and construction of an aesthetically unified residential and tourist commercial development incorporating the natural environment and the local history of the surrounding area. The design guidelines are intended to: • Ensure the extensive open space elements of the plan are visible and available to all residents. • Assist in implementing the design intent of the Specific Plan by establishing project compatibility among different residential densities and land uses. • Provide a consistent approach to site planning and the design of buildings, streets, signage, walls and fences, lighting, landscaping and other+ design elements that will endure the life of the community. • Ensure the placement of structures consider the environmental conditions including sun orientation, prevailing winds and on and off-site views. • Ensure the residential development edges are softened by landscape whenever possible. • Promote the orientation of residential products to maximize vistas and access to open space uses. • Offer a variety of residential products, styles and lot configurations that will ease monotony and help to create a pleasing distinction of home types. • Ensure manufactured slopes have varied gradients and where appropriate are shaped to mimic natural landforms • Provide for a varied street scene by staggering front setbacks and garage orientations • Ensure all land uses are cohesively situated within the projects natural setting 3.2 Introduction The Travertine residential and tourist commercial land use plan has been designed to make the most of the benefits of the distinguishing qualities of its location and topography. The land use plan is influenced by and is sensitive to the environment in which the community is located. The Design Guidelines adopted as part of the Travertine Specific Plan consist of two principal components: Landscape Design Elements and Architectural Design Elements. These components define the design concept, physical character and overall design vision of Travertine. The Design Guidelines establish the framework to achieve a harmonious compatibility between the residential neighborhoods and project design features. 3.3 Theme Travertine draws its inspiration from the desert environment in which it is situated. The project’s unique setting finds itself at the base of the Santa Rosa mountains and upon completion will be surrounded by tens of thousands of acres of permanent open space as a backdrop for this one of a kind community. The large landforms, known as the historic Martinez Rock Slide as well as Coral Mountain acts as an inspiration for theming the project in terms of form, color, and scale. The goal of this project is to provide the highest quality residential and tourist commercial master planned community. DRAFT 3.0 DESIGN GUIDELINES TRAVERTINE SPECIFIC PLAN AMENDMENT – 2019 Page 3-2 The Resort/Spa portion of the project will provide a unique setting for wellness. The Resort/Spa will cater to a high-end clientele interested in state-of-the-art holistic healing methods as well as a recovery center that will define this exclusive Resort/Spa. The massing and scale of the Resort/Spa architecture is intended to blend with and mimic the Coral Mountain topography which borders the Resort/Spa. Architectural designs for the Travertine community may be contemporary or traditional interpretations of the common contemporary desert themed architecture; as long as they are comprised of a consistent and appropriate design vocabulary that is true to the principles of the style and stay within the constraints of location, program, and budget. It is the intention of these guidelines to foster a community of unique environmental design solutions that are appropriate for the project. 3.4 Architectural Design Elements The integrity of the architectural character of the project will be maintained through the application of guidelines stipulated within the plan and throughout the site. When used together the styles should be designed to create a neighborhood character that will be sustainable over time. Each home should contribute to the architectural character of the neighborhood. Design elements such as porches, recessed windows, architectural details and accents, garage configurations and orientations, and articulated elevations are encouraged to enhance individual homes and to promote the overall neighborhood character. The Architectural Guidelines suggest themes compatible with the Coachella Valley character but are not intended to limit expressions of varying architectural styles. The Architectural Guidelines section outlines selected architectural styles and massing by the proposed home types and densities for the project. Examples of six typical home sizes are listed below and styles can be found in Exhibits 3.1-3.6. Examples of typical estates, resort residential and villas are depicted in Exhibits 3.7-3.9. Low Density Residential • Estate Homes, Exhibit 3.1 • Single Family Luxury, Exhibit 3.2 • Single Family Mid, Exhibit 3.3 • Single Family Entry, Exhibit 3.4 Medium Density Residential • Patio Homes, Exhibit 3.5 • Single Family Attached Units, Exhibit 3.6 Every development proposal within the Travertine Specific Plan shall be reviewed by the City of La Quinta Planning Commission to assure its conformance with the intent of the architectural guidelines stated and illustrated within the document. However, it is intended that any other suitable designs proposed that may not be specifically mentioned in this document, but is consistent with the initial theme, may be considered and approved for use. The guidelines below describe general attributes that are common to all architectural examples, yet it is the way that they are adapted and modified to suit a particular style that creates a richness of diversity in a master planned community. Accordingly, these Design Guidelines are provided as a resource to those involved in the design and implementation of this Specific Plan and illustrative in nature and meant to be flexible and respond to the changes in taste over time. DRAFT 3.0 DESIGN GUIDELINES TRAVERTINE SPECIFIC PLAN AMENDMENT – 2019 Page 3-3 Massing and Scale: • The size and scale of the building shall be proportionate to the size of the lot and building’s setting in compliance to setbacks; • Provide variable setback to different parts of the dwelling unit to encourage vertical and horizontal massing breaks; • Varied garage layouts and floor plan configurations that create more desirable proportions and neighborhood curb appeal; • Projections and recesses that provide shadow and depth; • The addition of balconies or porches is highly encouraged to improve the scale and massing of two- story homes. • The solar orientation of the buildings will be a key consideration in the design in order to reduce the impact of the development on the local utilities. • Building Articulation: • The roof ridgelines, heights and slopes of the homes shall be appropriate to the intended architectural style; • Design elements such as fireplaces and chimneys add interest with added articulation to home designs. • Porches, Balconies, Stoops, and Decks • Front porches, balconies, covered terraces, courtyards are key elements used to provide outdoor living spaces; • Porches, balconies and covered terraces shall be authentic to the architectural style of the home; • Porches, balconies and covered terraces should be in proportion to the scale of the building; • Decks and balconies shall be of adequate size to serve as outdoor spaces; • Decks and balconies of adjacent homes shall be staggered to protect privacy of neighbors and • Decks and balcony posts, trims and balustrade railings shall be consistent with the architectural style of the home 3.4.1 Color The proposed architectural color motif will be desert compatible, using a palette of earth tones. This harmonious and pleasing palette will be completed with a variety of accents, roof tones and textures, with complementary window moldings and architectural detailing. The predominantly earth tone structure colors will range from beiges, gray-green tones, mauves, whites, creams, tan, sand, light browns, and similar earth tones 3.4.2 Materials Roofing material shall be compatible with architectural features and resistant to the harsh desert climate. In addition, stucco, rock façade, tile, and materials resistant to the desert environment will be utilized in the construction of the buildings onsite. Energy efficiency will be a major consideration when designing the homes and buildings in the development. Unsuitable materials, such as unprotected exposed metal, equipment and venting, unprotected wood, and vinyl, will be prohibited. Examples of materials that may be used are found in Exhibit 3.10. Sustainability is a major consideration of the City of La Quinta and the region as a whole. When possible, rapidly renewable materials will be considered and used in the construction of the buildings in Travertine. It also will be important to consider the construction waste generated from the site and prevent raw materials from entering the landfills by making a conscious effort to minimize waste and utilize recycling programs. DRAFT 3.0 DESIGN GUIDELINES TRAVERTINE SPECIFIC PLAN AMENDMENT – 2019 Page 3-4 3.4.3 Fences and Walls For purposes of this section, “fence” or “wall” means any type of fence, wall, retaining wall, sound attenuation wall, screen or windscreen. The terms “fence” and “wall” are used interchangeably in this section to mean any or all of the preceding structures. All fencing and wall use are subject to the City of La Quinta municipal 9.60.030 Fences and walls should reflect the materials and design of the approved home façade. The treatment of the wall should match the architectural treatment of the residential building, or the walls and/or fences that are an integral part of the garden design. Examples of materials that may be used for fences and walls are found in Exhibit 3.11. Low freestanding courtyard walls, gateposts and entry monuments under six (6) feet high may be integrated into the driveway or auto court-design. Walls, fences, terraces and outdoor landscape areas should appear to be extensions of indoor areas and the building architecture, rather than as independent elements. Walls shall be architecturally compatible with the house and built of similar materials and colors “Drive through” archways or beams may be permitted on a case by case basis with the approval of the City. The design concept, therefore, is to make fences and walls blend with both the architecture and the landscape, while still providing privacy and security consistent with the needs of individual lot owners. Fences and walls placed on lots shall be an extension of the colors and materials of the adjacent residential architecture, visually compatible and be of materials related to the land (such as stone). They may occur as an extension of house living spaces, to frame courtyards or to direct views. Wrought iron fencing styles and downslope fencing techniques are encouraged to maintain views. The following requirements apply to all fences and walls within the Travertine Community: 1. Walls and fences should be kept as low as possible while performing their intended function. Wall height should be minimized to avoid a “fortress” appearance. The design of fences and walls, as well as the materials used, should be consistent with the overall house design. 2. Appropriate materials for walls and fencing include tube steel, river rock stone veneer, split face block and slumpstone block. 3. Fence and wall colors should match or complement the color of the building. 4. Tops of retaining walls should blend with natural contours. Ends of walls should not end abruptly, but are to transition into existing landforms, rock outcroppings and vegetation. 5. Plant materials are encouraged to be woven in and around fences to help fences merge with the landscape. 6. Adjacent to a Nonresidential Zone or Uses, the maximum fence height between a residential zone or use and a nonresidential zone or use shall be eight feet. Prohibited Fence Materials and Construction Fences include, the use of barbed wire, razor wire, chain link, or similar materials in or on fences is prohibited in all residential districts. Chain link fencing is permitted for temporary construction fences when authorized by a minor use permit issued in accordance with Section 9.210.020. Said minor use permit shall not be approved until a permit for grading, or construction, has been filed for, whichever comes first. 3.5 Landscape Design Elements The primary purpose of the design guidelines for landscape architecture is to ensure that landscape treatments and materials utilized in Travertine will enhance the high-quality aesthetic impression to be achieved while also complementing the physical design and architectural features of the community. It will also be important for the sustainability of the project to consider only those plant materials that utilize DRAFT 3.0 DESIGN GUIDELINES TRAVERTINE SPECIFIC PLAN AMENDMENT – 2019 Page 3-5 minimal amounts of water. The landscape elements are planned to accent entrances and soften hard surfaces and structures. Landscape materials and elements selected should be appropriate for the climate of the area which includes hot dry summers and moderate winters. All landscape materials are in compliance with CVWD standards. Examples of landscape treatments are found in Exhibits 3.11–3.31. The experience of both arriving and leaving the Travertine project from the north east extension of Jefferson Street will be enhanced by the abundance of open space between the dike and the Resort/Spa property. The area between the dike and Resort/Spa will be permanent open space under the control and management of the CVWD. Proximity to the open space will heighten the exclusivity and the feeling of protection provided by this project feature. Generous setbacks will be provided along Jefferson Street and the edges of development. The open space and landscape elements will emulate the simplicity and beauty of the existing environment. The Landscape Design Guidelines section presents general imagery for entries, streetscapes, community slope, parks, trails and project edge conditions. A plant palette provides a specific list of plants that reinforces the community design character and which is compatible with the surrounding natural open space. The plant lists are organized by plant type and are found in Table 4.

The primary community landscape elements shown in Exhibits 3.12-3.24 are: • Project Entries / Gates; • Jefferson Streetscape; • Loop Roads Streetscape; • Parks and Trails; • Community Slope; • Round-A-Bouts; • Golf Course and Open Space; and Edge Conditions. These landscape elements will occur throughout the community and unite Travertine under a common design theme and plant palette. General guidelines and design criteria for the community landscape elements are described throughout this section. All landscape plans will be submitted to the City for review and approval. The following Exhibits display conceptual ideas of desert themes and layouts for the Travertine Project. The landscaped sections, Exhibits 3.25–3.31 show the relationship of the project land uses to one another and from the built environment to the projects’ natural edges. 3.5.1 Project Entries and Gates: The extension of the secondary arterial connection between Jefferson and Avenue 62 will be an ungated public road. Gating will occur to serve the uphill and downhill portion of the project, both of which are in the loop roads, connected to the Jefferson and Avenue 62 arterial road. A third gate is proposed at the entry to the Resort/Spa (PA-2). The treatment of 4 primary gated project entries and the roundabout intersections within the Travertine Specific Plan area establishes the overall community character for the project while forming a design hierarchy. These thematic features are created through a blend of hardscape elements and plant materials which become the first impression for all visitors and residents entering the community. These entry experiences will help define the character of Travertine DRAFT 3.0 DESIGN GUIDELINES TRAVERTINE SPECIFIC PLAN AMENDMENT – 2019 Page 3-9 by complementing the surrounding natural environment, shown in Exhibit 3.3.20. 3.5.2 Jefferson and Loop Road Streetscapes: The landscape character of Jefferson Street will be relaxed with large expansive parkways, and sloping setbacks to development. The two roundabout intersections on Jefferson provide access to the residential neighborhoods along the loop roads. The parkways along the loop roads are designed with a 9-foot parkway in order to provide ample room for a pedestrian walk separated from the street by a landscape buffer, shown in Exhibit 3.14 and Exhibit 3.15. Local street landscapes will be designed in a unified matter with the master road system of the project, see Exhibit 3.24. The landscape character of the streets in Travertine is a significant element in creating the perception of the community character unification and quality. These common landscaped areas link vehicular and pedestrian traffic to the neighborhoods and the community amenities. The streetscapes are treated as community spaces providing a clear hierarchy of pedestrian and vehicular circulation. Shrubs, low groundcovers, grasses and perennials will be used to reduce maintenance, conserve water and provide a buffered separation between pedestrian and vehicular traffic. Utility features will be coordinated with the landscape plan to ensure that above-ground utility structures are visually screened. Sections 10-12, Exhibit30, show the Jefferson Street landscaped slopes where the gradient has been softened to a 5:1 ration to both emulate the natural slope of the property and provide spacious setbacks between the street and the residential land uses. Section 11 cuts through two residential uses and the secondary access to the Resort/Spa from the Travertine community. 3.5.3 On-Street and Off-street trails: Private trails are located on Jefferson Street and throughout the community. The proposed system of trails and paths throughout the Specific Plan area forms a centerpiece of the park and recreation plan. The trail system provides a link for walkers, joggers and cyclists, connecting neighborhoods, parks and open spaces. The landscape areas within Travertine focus on the use of plant materials characteristic of Coachella Valley materials and colors. It is important to make a strong connection with the natural open space surrounding the community, while also providing a pleasing landscape for common areas within the streetscapes and off-street trail areas. The informal landscape theme of the spine trail will include benches, and areas to relax and enjoy the views of the surrounding mountains and valleys. Native and non-native trees will provide shaded areas and shrubs and grasses will add color and texture.See Table 9 for a list of prohibited invasive ornamental plants.

Shade trees, benches and picnic areas, tot lots and dog parks will make these passive parks an enjoyable space for the residents to meet. The community parks will supplement the private parks located within the individual residential developments, see Exhibit 3.17. A community clubhouse is proposed for the community park north of Jefferson Street. Sections 1-3, Exhibit 3.27, show the natural condition along the projects’ western boundary to the development. The multi-use trail runs along the western boundary and separates the natural environment from the projects graded slopes. Slopes along this edge are generally graded at a 2:1 ratio; along with the outer edge, they will also be reinforced for flood protection. Sections 13-15, Exhibit 3.31, the spine trail that connects both community parks are shown in Section 13. This trail will be 10 feet wide and will accommodate pedestrians and cyclists to provide off-street access to the community amenities. Section 14 demonstrates the loop road system and the generous setbacks to residential development. Slope gradients on either side of the street are at a 5:1 ratio to allow for landscape and distance to separate homes from the street. Section 15 is located on Jefferson Street between DRAFT 3.0 DESIGN GUIDELINES TRAVERTINE SPECIFIC PLAN AMENDMENT – 2019 Page 3-11 the two-project round-a-bouts. Again, the slope gradients are softened to a 5:1 ratio to provide large setbacks to residential uses. 3.5.5 Public hiking trails: Public hiking trails surround the perimeter of Travertine and can be accessed from the staging areas located on the south side of Jefferson Street near Avenue 62, the staging area to the north of the project on the east side of Jefferson. These trails are routed along some of the most scenic locations in the area and will connect hikers to the Boo-Hoff trail. 3.5.4 Golf Course: Golf course uses will transition to the low-water landscaping options presented in the plant palette . Turf will be limited to those areas of active golf uses; the course will have a desert theme. The transition between the golf course and the Martinez Rock Slide, and the transition between the golf course and the sensitive archaeological area in the east are illustrated in Exhibit 3.19. The golf course and its amenities will be set against a desert landscape with mountain vistas views. Additionally, the landscape of the Jefferson Street corridor and the adjacent slope is illustrated in Exhibit 3.14. Sections 4-6, Exhibit 3.28, represent the relationship of golf uses along the southern edge of the property to the golf facility uses and residential uses. Sections 7-9, Exhibit 3.29, generally represent the north eastern boundary of the project and show the relationship between the residential uses, the trail and beyond the property boundary to the natural ground. Section 9 shows the connection between the Resort/Spa use and the preserved Coral Mountain. 3.5.5 Plant Material Guidelines: It is the intent of these guidelines to provide flexibility and diversity in plant material selection, while maintaining a limited palette in order to give greater unity and thematic identity to the community. The Travertine landscape plan will be limited to the plant palette contained in Table 4, which is in compliance with CVWD requirements for low-water landscaping and reflects the desert environment of the surrounding areas. The goal of the landscape plan is to achieve water conservation through the design of the plan and use of native materials. The limited selection of materials used in simple, significant composition, complementary to adjacent common landscape area and reinforcing the individual architectural and site setting is encouraged. Overall plant material selection for given project areas shall have compatible, drought resistant characteristics. Irrigation programming can then be designed to minimize water application for the entire landscape setting, and will require smart landscaping systems. DRAFT
