Central Texas Character: Rancho Sienna is situated on the eastern edge of the Texas Hill Country, a region featuring rugged hills consisting of thin layers of soil atop limestone or granite which contributes to its unparalleled diversity and beauty. In the spring, roadsides and fields are splashed with colorful wildflowers. Autumn brings vibrant reds, oranges and yellows as the vegetation announces a new season. Although winters are usually mild with few hard freezes, summers usually mean drought and extreme heat. The native plants of the area are those that can survive and thrive in these extreme conditions. It is difficult for most non-native plants to survive without a lot of supplemental water and soil improvements and fertilizers. Much of Central Texas’s foundation is caliche, is a sedimentary rock that is a hardened deposit of calcium carbonate. Thin clay soil barely covering caliche and large rocks doesn’t seem like a good start for most plants but many plants thrive under these conditions. In fact, there are trees found only here including the sycamore-leaf styrax and the Anacacho orchid tree. Selecting plants that are native and/or well adapted to the area preserves the unique beauty of Central Texas and provides a wide range of plant materials to select from that will be able to endure the region’s extreme conditions. RANCHO SIENNA COMMUNITY DESIGN GUIDELINES - JUNE 2014 5 LANDSCAPE LANDSCAPE DESIGN GUIDELINES ? Did you know... Garden pests account for a mere 1% of all insects in a typical garden. Beneficial insects are nature’s pest control but pesticides kill both pests and beneficial insects alike. 2 Habitat The Hill Country is home to large and small mammals, birds, lizards, and insects. They live in and off of the grasses, wildflowers and trees. Integrating native plants into private yards not only will allow birds and butterflies to pollinate other gardens, but creates a larger network of habitats and havens for many species of wildlife including songbirds and beneficial insects. Enjoy the sights and sounds of nature in your front and back yard. Songbirds and butterflies are welcome visitors, but don’t forget about the insects. Insects are not just food for the birds, they help protect your garden. Beneficial, predator insects keep garden pests away and eliminate the need for toxic chemicals. Water Conservation: While creating habitats and maintaining the natural characteristics of the region are important, the most compelling reason to use native plants is water conservation. Plants that are native to where you live have been growing there successfully for millennia and are well-adapted to the http://www.cals.ncsu.edu/course/ent010/ soils, temperatures, and annual rainfall. Natives can exist on rainfall alone. Rancho Sienna is interested in encouraging water conservation and also educating residents on how to create water-efficient, beautiful landscapes. By using native plants that require less water, you will help conserve this precious resource while saving you time from hand watering during times of water restriction and saving money on your water bills. RANCHO SIENNA COMMUNITY DESIGN GUIDELINES - JUNE 2014 6 LANDSCAPE LANDSCAPE DESIGN GUIDELINES 3 Creating a Native Landscape The challenges of gardening in Central Texas are thin soils, hot weather, droughts, and torrential downpours. FOUR MAIN ISSUES to address in creating a healthy, attractive, and easy to maintain landscape are soils, plant selection, landscape design, and efficient irrigation and drainage. 3.a. Soil Good soil is the foundation of a healthy, drought tolerant landscape. Six to eight inches of compost-amended soil improves plant health, increases a yard’s ability to stay healthy through dry periods by retaining water, and decreases runoff by allowing water to filter through the layers of soil and rock. Soil Amendment: • Reuse native soils whenever possible. • Topsoil shall contain a minimum 20% organic material or compost blended with sand and loam at approximately 10% sand and 65% loam. Caliche, the sedentary rock just below the soil, is not considered topsoil. • Turf grass areas shall have at least six inches (6”) of topsoil. • Planting beds shall have at least six inches (6”) of topsoil. • All soil shall be free of debris and rocks greater than one inch (1”) in diameter. • In order to achieve sufficient soil depth, you may need to add soil. When adding topsoil, combine existing soil with new soil two to three inches (2” -3”) deep to encourage water filtration through layers of soil. 3.b. Edging and Raised Plant Beds: Edging creates clean, visible edges to plant beds. Spaded, or shoveled, edges may be used or the homeowner may want to consider using a structural edge. These materials serve several practical purposes. They allow you to retain more soil to maintain a sufficient base for plants. Edging can also facilitate maintenance. • Small shrubs, ground covers, and perennials require a minimum of six inches (6”) of soil to be well-rooted. Soil depth should be increased for plants with larger root balls such as large shrubs and trees. Consider raised beds, berms, or terraces in locations where soil is thin. • Landscape beds may be bordered with an acceptable edging material. Edging shall not be installed along sidewalks. • Acceptable Edging Materials: Stone, Steel, Concrete (poured in-place) RANCHO SIENNA COMMUNITY DESIGN GUIDELINES - JUNE 2014 7 LANDSCAPE LANDSCAPE DESIGN GUIDELINES • Unacceptable Edging Materials: Plastic Products, Wood Posts, Landscape Timbers, Rail Road Ties, Scalloped Precast Concrete Edging. • Where steel edging is used, the top of the edging shall be a maximum of one inch (1”) above finish grade of adjacent lawn areas. The top of the edging should be flush with paving where it meets sidewalks or hardscape features. • Add interest to plant beds and edging by adding landscape boulders. Boulders benefit plants by providing shade for roots. Stone Steel • Concrete Landscape boulders Soil depth and quality is important for plants to grow and thrive. This can be achieved by creating raised plant beds. • Raised beds, terraces, or decorative walls must be made of or faced (veneered) with masonry (stone, stucco, or approved equal). Do not use standard concrete blocks, plain or painted. These will help to relate the landscape to the house if constructed of the same material (or complementary in finish and style). • Cut or fill slopes along the exterior of the wall shall be smooth and taper gradually to match existing grades. • Maximum height of decorative walls should be measured from the finished ground elevation on the highest side of the wall and shall not exceed three feet (3 feet) in height. • Be sure that raised beds do not result in soil or moisture against exterior house walls above the level of masonry weeps and the floor. RANCHO SIENNA COMMUNITY DESIGN GUIDELINES - JUNE 2014 8 LANDSCAPE LANDSCAPE DESIGN GUIDELINES • Acceptable Wall Materials: Masonry, Brick, Stone, Stucco, Split-face Concrete Block with cap. • Unacceptable Wall Materials: Standard Concrete Block, plain or painted • Decorative or planter walls that are partially below the finished grade shall be moisture-proofed to avoid unsightly water staining. Terraces Raised stone planter Low stucco wall 3.c. Mulch: Mulch plant beds to combat weeds, keep soil cool and moist, and give your yard a finished look. • All areas planted with trees, perennials, and shrubs shall be finished with a 3 inch deep layer of high quality organic mulch, or rock mulch. • Decomposed granite is a good alternative mulch for many heat loving native plants. • Acceptable Mulch Materials: Shredded Cedar, Shredded Hardwood, Cypress, River Rock, or Decomposed Granite. • Unacceptable Mulch Materials: Lava Rock, Rubber Mulch, Color-Enhanced Wood Mulch, or Redwood Mulch. River rock Decomposed granite RANCHO SIENNA COMMUNITY DESIGN GUIDELINES - JUNE 2014 Wood 9 LANDSCAPE LANDSCAPE DESIGN GUIDELINES 4 Plants A common misconception of native landscapes is that they are unsightly and hard to maintain. Native plants can be both beautiful and hardy. In addition to natives there are well-adapted, non-native plants that perform well in Central Texas soil and climate conditions. Planting native and welladapted plant material has many built-in benefits. They play an important role in creating an attractive and manageable garden at the residential scale, while directly benefiting the environment at the neighborhood, community, and regional scales. ? Did you know... The California Fan Palm, Washingtonia filifera, is the only species of palm tree that is native to the continental United States west of the Hill Country’s Balcones Fault. The use of native and adapted plants in the Texas Hill Country landscape ensures three important things. First, homeowners can appreciate that their landscape will take on the regional character of Central Texas. Second, it will thrive during times of drought. And third, it will not only require less supplemental water, but it will also require a lot less time and maintenance because native plants rarely need pesticides or fertilizers. Attractive, colorful, l f l and d easy to maintain native landscape. l d RANCHO SIENNA COMMUNITY DESIGN GUIDELINES - JUNE 2014 10 LANDSCAPE LANDSCAPE DESIGN GUIDELINES 4.a Plant Selection and Placing: • Shrubs and flowers should be selected from the native and well-adapted plant list at the end of this manual. • No more than 50% of the planting area in the front yard shall be planted in turf. • Invasive plants shall not be used. Refer to Suggested Plant List. • Masses of one species will eliminate a scattered appearance that is often associated with a native landscape. Grouping a single species into clusters of five to seven plants helps to achieve blocks of color and texture. ? Did you know... Late February through early May and September October are the perfect time for planting perennials, grasses, turf and shrubs. Tree planting season is October - March. • Plant the right plant in the right place. Group sun-loving plants together in the sun and shade-loving plants in the shade. Allow plants adequate space to grow. Refer to Suggested Plant List for suggested spacing. Ornamental Grasses Native Plant Material • Trees shall not be planted in utility easements. Shade trees shall not be planted closer than twenty five feet (25’) from above ground utility lines and five feet (5’) from underground utilities. RANCHO SIENNA COMMUNITY DESIGN GUIDELINES - JUNE 2014 11 LANDSCAPE LANDSCAPE DESIGN GUIDELINES 4.b. Lawn Care: • Reduce turf to meet your aesthetic or family lifestyle needs because grass generally requires more water and chemicals to maintain. • Turfgrass shall have summer dormancy capabilities to insure that landscapes will survive under mandatory water restrictions. ? Did you know... Taller grass shades its own roots, lowering evaporation and requiring less water. So let your grass grow longer in the summertime. Little or No Turf • In a sunny yard, Zoysia is recommended. Buffalo grass is in keeping with the native plant character but can be prone to weeds and does not tolerate a lot of foot traffic. • In order to create a uniform look throughout the community, Bermuda grass must be used in turf areas in front yards and areas visible from the street. Homeowners may choose to use alternate grasses, such as Zoysia or buffalo grass, in rear yards. • Bermuda is a low water-use option but can be invasive. Use hybrid species only e.g. Tif 419 Bermuda. • Fertilization of turf areas shall not be required. If turf areas are fertilized, natural or certified organic fertilizers with less than 4% phosphorus shall be used. RANCHO SIENNA COMMUNITY DESIGN GUIDELINES - JUNE 2014 12 LANDSCAPE LANDSCAPE DESIGN GUIDELINES 5 How to Plant: • Planting at the right time allows plants to establish themselves with minimal stress. Avoid planting during the summer in Central Texas. • To keep plants from sinking into the planting hole over time, dig holes to be only as deep as the root ball in the pot. • For root-bound plants, cut through any roots that seem to be wrapping around and around the root ball. This allows plant roots to grow outward for better stabilization and nutrient and water uptake. ? Did you know... Half of all stormwater pollution comes from residential property. That pollution is from products we use for our yard care and household activities and from our yard waste. • To keep roots from drying out, firmly pack soil back around the plant once it is in the planting hole. • Thoroughly water plants just after planting to help settle the soil and remove air pockets. • Keep soil moist, but not wet, for several months after planting to establish root systems. Before watering, allow soil to become almost dry. • Cut back on irrigation once plants are established. Drought-tolerant plants only require occasional supplemental watering during dry summer months. • Avoid over-watering and enjoy lower water bills. RANCHO SIENNA COMMUNITY DESIGN GUIDELINES - JUNE 2014 13 LANDSCAPE LANDSCAPE DESIGN GUIDELINES 6 Landscape Design Rancho Sienna is part of the Hill Country and each home should be reflective of this natural beauty. Create outdoor rooms and offer a variety of experiences by utilizing plant beds and pathways or hardscape. Several things to consider when designing your landscape are water drainage, sunny and shady areas, and what activities you and your family enjoy. For additional design ideas, visit the Chisholm Trail S.U.D. Landscape Laboratory in Florence or the Lady Bird Johnson Wildflower Center in Austin. 6.a. Drainage Swales and Rain Gardens: • Create a “dry creekbed” to direct water draining on your property. Direct water to a lower spot where it can better infiltrate the soil. • Low areas of your landscape that capture water and allow it to soak into the ground are called “rain gardens.” Rain gardens can either be filled with plants for both wet and dry conditions or they can be filled with only stone. • For rain gardens, do not add weed barrier fabric as this reduces the water’s ability to soak into the ground. • Divert water from roof downspouts into rain gardens. These gardens act as filters for overflowing water on the way to storm sewers. • Rain gardens allow water to soak into the ground. Overflow eventually runs into storm sewers. Low spots make good rain gardens RANCHO SIENNA COMMUNITY DESIGN GUIDELINES - JUNE 2014 Dry creekbed 14 LANDSCAPE LANDSCAPE DESIGN GUIDELINES 6.b. Hardscape • Creating seating areas, outdoor dining areas, or pathways using decorative paving materials. Stamped & stained concrete Decomposed granite and flagstone Seating area • Acceptable Materials: Washed-Aggregate Concrete (aggregate less than 3/8” for slip-resistance), Stamped & Stained Concrete, Decomposed Granite, Stone, Brick or other Unit Paver • Use pervious pavement such as stone without mortar, mulch, or porous concrete to allow water to soak into the ground. 6.c. Habitat Many people enjoy the sights and sounds of songbirds calling, frogs croaking, or butterflies floating by. Attracting wildlife such as hummingbirds and songbirds, lizards, and insects is easy if you provide food, water, cover, and places to raise young. • Create a buffet for wildlife with nectar, pollen, nuts, seeds, and berries by planting a variety of native plants. • Bird baths, small ponds, and rain gardens provide water for wildlife. Animals need water for drinking and some need it for breeding. RANCHO SIENNA COMMUNITY DESIGN GUIDELINES - JUNE 2014 Plant diversity and boulders create habitat 15 LANDSCAPE LANDSCAPE DESIGN GUIDELINES • Offer shelter from predators and bad weather with stacked rock walls and landscape boulders, planting layers of vegetation, or by planting evergreen shrubs. • Dense shrubs, a bird house, or pond are examples of places wildlife need to mate and raise their young. 7 Irrigation Shrubs, trees and lawn all need water, but not the same amount of water. Be sure to water plants according to their need. Know your watering schedule and change it seasonally. Whether you’re hand watering or using modern efficient irrigation equipment, here are few things to keep in mind. 7.a. Efficiency • Water no more than twice a week and comply with watering restrictions of the local jurisdiction(s) during drought. • Group plants with similar water needs together. This is called “Hydrozoning”. ? • Apply only enough water to moisten the root zone of plants six to eight inches (6”- 8”) deep, then allow soil to dry before watering again. In thin Hill Country soils, apply a maximum of 1/2” of water twice a week. • The best time to water is from dusk to dawn. Sun and wind cause evaporation and keeps plants from getting the water they need. Early morning watering allows the sun to dry the plants’ foliage, preventing pest problems. RANCHO SIENNA COMMUNITY DESIGN GUIDELINES - JUNE 2014 Did you know... According to the Irrigation Association, up to a 50% water savings can be achieved by increasing soil depth for a turf area from 4” to 8”. Compost increases the water holding capacity of soil which decreases runoff and improves plant health. 16 LANDSCAPE LANDSCAPE DESIGN GUIDELINES • Another way to decrease evaporation is to use low-angle sprinklers that produce droplets of water. Also consider low flow (drip and micro spray) equipment. • When hand watering or using irrigation system, “cycle and soak”. Apply a little water at a time allowing water to soak in and decreasing run-off. • Direct sprinklers toward lawn and away from pavement. RANCHO SIENNA COMMUNITY DESIGN GUIDELINES - JUNE 2014 17 LANDSCAPE LANDSCAPE DESIGN GUIDELINES 7.b. Irrigation System Types ? Did you know... Evaporation Today there are many types of automatic irrigation systems can be as that reduce water use by incorporating low-output or low-flow sprinklers, and controllers that use weather-based calculations high as 40% during and environmental conditions to determine the amount of water the heat of summer, applied to a landscape based on the plants’ water needs. Use so be sure to water at a sprinkler that emits large drops of water close to the ground dusk and dawn. and avoid one that sprays a fine mist into the air. Drip irrigation systems take longer to wet the soil but they lose very little water to evaporation. Because different plants require varying amounts of water, several types of heads may be used on one site. Different zones should be used for these varying irrigation head types and plants. Bubblers work well for trees by providing a large amount of water, drip irrigation is well suited for shrubs and ground cover because water is applied on the ground and close to the roots, while sprays and rotating streams water turf areas.

Rainwater Harvesting • Use of rain barrels, tanks, and bladders to capture water from roofs and reuse on landscapes is encouraged. • Rain barrels must be located in rear yard or side yards with surrounding planting, or fencing to screen the view from the street. • To use captured rainwater for automatic irrigation, a small pump is required to pressurize the water for use. A licensed irrigator with experience in rain water harvesting can assist in the design of a complete system.

Planting plans shall emphasize native, ornamental grasses and other plants that are native and/or well adapted to Central Texas for long-term success of your yard. RANCHO SIENNA COMMUNITY DESIGN GUIDELINES - JUNE 2014 20 LANDSCAPE LANDSCAPE DESIGN GUIDELINES 9 Landscape Requirements 1. Plant no more than 50% of your yard in turf grass. 2. Soil in planted areas, including turf and plant beds, shall be a minimum of 6” of high quality topsoil. Topsoil shall be native soil from the site, or fertile, friable, blended sand/loam/compost topsoil. Non-native topsoil shall contain not less than 20% organic matter (compost) that is blended through the soil. Incorporate topsoil into existing surface by first loosening any compacted soils. Do not place more than 2” of topsoil within the drip zone of existing trees; instead feather from deeper topsoil to the drip zone. 3. Trees and plant beds shall be topped with a 3” deep layer of high quality organic mulch. 4. See Design Guidelines for list of acceptable materials for edging, raised plant beds, mulch, and hardscapes. 5. Rock mulch or river gravel may be used in areas that are narrow or areas with foot traffic and/or seating. No more than 20% of a yard within public view may contain an unplanted area. An unplanted area is an area of more than 30 square feet without a plant. If rock mulch is used, plant material shall be incorporated to soften these spaces. 6. Group plants based on sun and water requirements. 7. At minimum, 90% of plant material shall come from Suggested Plant List located in these guidelines. No invasive plants or plants from the Do Not Plant List are allowed. 8. Plant beds shall be sized appropriately to allow correct spacing of plants within the beds. Plants need sufficient space from structures and other plants to grow to full size. 9. Non-turf planting may include ground cover plants of appropriate size. Such plantings shall minimize encroachment onto the sidewalk. Avoid planting plants with spines or sharp edges near walkways or pedestrian areas. 10. Turf in front yards and areas visible from the street must be Bermuda hybrid seed or sod as specified in the Suggested Plant List of this guide. Homeowners may choose to use alternate grasses, such as Zoysia or buffalo grass, in rear yards. 11. Trees shall not be planted in utility easements. RANCHO SIENNA COMMUNITY DESIGN GUIDELINES - JUNE 2014 21 LANDSCAPE LANDSCAPE DESIGN GUIDELINES 12. A minimum distance of fifteen feet (15’) shall be maintained between all shade trees. Trees are to be planted a minimum of four feet (4’) behind the sidewalk. 13. For Builders installing landscapes, each house floor plan shall contain a different planting plan. These guidelines are to be applied to landscape improvements on each lot, within public view. Home builders remain responsible for landscape requirements within public rights-of-way, including designated street trees, sod and irrigation between street curbs and sidewalk. 14. Before digging deep into the ground, verify where utility lines are located. At least three days before you are ready to dig, call the Rancho Sienna Reviewer office at 254-793-3103 and call 1-800-DIG-TESS (344-8377) and provide the location of your excavation project. 15. Trees: • Before submitting a plot plan for approval, builder shall visit the home site to catalog existing trees and ensure minimal impact to existing trees. Submitted plot plans should indicate any existing trees to be maintained (per the Neighborhood Diagram and per on-site visit) as well any smaller trees that must be removed. • Builders will get “credit” for protecting trees on the home site; those trees will count toward the minimum tree requirement of at least two trees. Trees should only be removed when necessary to properly place a home on a home site. Tree and Shrub Chart: Refer to Section 5.12 Suggested Plant List.

Submittals The Applicant shall submit drawings of a typical landscape for each house floor plan to be built at Rancho Sienna. Upon completion of the landscape installation, the RSR shall review the installation for compliance with the requirements and shall issue written comments or approval. Favorable reviews of initial submittals will neither imply nor guarantee acceptance of subsequent design submittals. Applicant’s Landscape Plan, Installation, and Review 1. Applicant shall visit site to note slope and drainage conditions, utility locations, and to verify existing site conditions. 2. The landscape must be constructed in accordance with Rancho Sienna Residential Landscape Requirements. Approval is required by the RSR prior to construction of any modifications to approved house floor plans. 3. Upon completion of landscape, the Applicant shall submit Checklist and Review and a site plan (at a minimum scale of 1”=20’) to RSR for review. The site plan, one for each house floor plan, shall show typical boundary lines, setbacks, and easements. The outline of the house is to be shown with dimensions sufficient to show typical location on the lot. Driveways, walkways, sidewalks, and patios are to be shown. Landscape beds, turf areas, locations of tree and plant species and quantity must be shown. The Applicant must consider adjacent lot’s landscape plan to avoid repetition of landscapes. 4. All plans shall include the following “Landscape Plan Notes”: A. A minimum of 90% of installed plant material for each lot shall be from the Suggested Plant List in the Ranch Sienna Design Guidelines and Residential Landscape Requirements. No invasive plants or plants from the Do Not Plant List are allowed. RANCHO SIENNA COMMUNITY DESIGN GUIDELINES - JUNE 2014 42 LANDSCAPE LANDSCAPE DESIGN GUIDELINES B. The minimum size of all plants shall be in accordance with the Suggested Plant List in the Rancho Sienna Design Guidelines and Residential Landscape Requirements. C. Narrow areas of turf less than 3 feet wide shall be avoided. D.
