Wallis Ranch presents a rare opportunity to create a new community that carefully blends traces of early California character with a modern touch of today's lifestyle. Natural riparian corridors and rolling open space help to frame the edges of the community as the undulating terrain of Wallis Ranch provides dramatic open vistas and view corridors that help to build its character. The creation of pedestrian-oriented neighborhoods was a majorfeature in the overall design of Wallis Ranch.Each of the eight neighborhoods embodies their own unique characterworkingto create a sharedsense of community throughout the generous mix of housing types. Walkable tree-lined streets,paths and trails,and interconnected spaces,all anchored by a community park and clubhouse that appeal to all residents. The overall landscape theme is a refined interpretation of an Agrarian/California Ranch landscape. Stone walls, orchard grids, and native grass plantings are used to reinforce the theme in key areas. Landscape and open space guidelines described on the following pages are intended to achieve this goal. Basic Design Principles • The streetscape system provides a visually unifying thread for the community.The circulation system is a clear hierarchy of streets that logically steps down in size from the Upper Loop Road to the cul-de-sacs. Street widths and landscape character reinforce the friendly neighborhood ambiance. • The open space system provides the community recreation opportunities and celebrates the agrarian setting. • The community fencing and wall system will be designed to visually recede into the setting to the extent possible. • Management of open space and maintenance of common areas will be an integral component of the landscape system.

With an emphasis on place making, Wallis Ranch invites its visitors in with a sequence of experiences that work to build the character of the community. • The Main Entry sets the thematic tone by incorporating many of the materials that are present throughout the community.The windmill and water tank reinforce the ranch theme as well as serve as some of the community's iconic landmarks. • The Bridge with a prominent mix of rustic charm and contemporary lines,builds a sense of drama as residents and guests traverse it. • The Anton Pavilion greets residents and guests as it overlooks the water quality basin.An ode to the historic school house that once called Wallis Ranch home,the Anton Pavilion serves as a gathering place along the multi-use trail. • The Entry Gate and pedestrian portal mark the arrival to the neighborhoods of Wallis Ranch. • The Community Clubhouse is the heart of Wallis Ranch.All eight neighborhoods surround this space which serves as the primary community gathering space. 1 4 ' • The Main Spine is the backbone of the community carrying the theme throughout the neighborhoods.

Use drought tolerant, deer-resistant plant materials. Select plants appropriate for selling from `East Bay Municipal Utility District Plant & Landscape for Summer — Dry Climates'. As recycled water will be used for irrigation, use plant materials tolerant of reclaimed water. Irrigation ' Irrigation throughout the public rights-of-way, and landscape setbacks shall be accomplished by means of automatically controlled spray, bubbler, and drip irrigation systems. The design shall incorporate water saving techniques and equipment and shall meet the water efficient requirements of the water efficient landscape ordinance adopted by the City of Dublin. Irrigation systems that use recycled water shall conform to the Dublin San Ramon Services District Recycled Water Use Guidelines. All irrigation systems shall be efficiently designed to reduce overspray onto walks, walls, fences, pilasters, street and other non-landscaped areas and into natural open space areas. All irrigation systems within the major streetscapes and common areas shall be designed to accommodate the use of recycled water in the event that it becomes available in the future. Irrigation systems shall be valved separately depending on plant ecosystems, orientation and exposure to sun, shade, and wind. The design shall be sensitive to the water requirements of the plant material selected and similar water using plants shall be valved together. Slope and soil conditions will also be considered when valving irrigation systems. * Y 68hrubs Groundcovcr 0 12 Wallis Ranch Design Guidelines !i i ro If f,INN • . .• ..•-. 1 • .. ..
