Like many cities in the country, nearly half of the water supply during summer is used on lawns and landscapes. These growing demands on water supply make it everyone’s responsibility to rethink appropriate use. This mindset does not need to come at the cost of aesthetics. Xeriscaping is not as simple as replacing plants with drought-tolerant plants. Xeriscape design is both a science and an art form. This requires a holistic approach to design that goes beyond plant selection and irrigation design. It must consider runoff, infiltration, filtration, stormwater and runoff capture, effective irrigation management, soils, mulch, non-living materials, roadway safety, cost and maintenance. We mention this because we have experience designing many types of road corridors for the past fifteen years. Consider our firm for the following reasons: • Within the last two years, we have completed six large-scale xeric designs that have achieved water savings ranging between 31 percent to over 90 percent. We have the tools to calculate your water savings. • Roadway safety can be compromised by landscaping. We are familiar with the MUTCD and AASHTO road design guidelines to ensure that your desire to have a drought tolerant median does not create other problems. • Not every landscape architect is also an irrigation designer. With over 100 irrigation systems designed, our landscape architects are also expert irrigation designers who are knowledgeable and experienced with the latest irrigation products, equipment, technologies and management strategies that increase efficiency and decrease water consumption, maintenance, labor and cost. • Roadway median landscaping requires a holistic approach that considers much more than planting and irrigation. It requires careful examination of many interrelated elements to achieve a functioning and aesthetically-pleasing design. We are ready to work with you to achieve your water reduction and roadway aesthetic goals.

Drought Tolerant Landscape & Irrigation Designs for City Medians2 Considerations for Roadway Landscaping The primary purpose of a road median, traffic circle or roundabout is to increase safety by managing the access of vehicles to adjacent properties and separating vehicular traffic. However, when plants are added, these roadway facilities can improve the aesthetics of streets and increase the environmental benefits. The design of these landscapes requires landscape architects who possess specialty knowledge, skills and abilities. Consideration #1: Soils Description: When it comes to a drought-tolerant/ xeric landscape, soils are as important as the plants and watering strategies. The two primary challenges for soil within roadways are quantity and quality. Medians often have a shallow soil profile and can be compacted, which restricts plant growth and water holding capacity. The quality of existing soils and proposed fills (if any) must be assessed as to their drainage characteristics, compaction potential, organic content, fertility and exposure to foreign materials/soil contaminates. Strategy: Peaks to Plains Design will assess the soils and make design decisions that will provide a sufficent depth of soil for plant growth, as well as ensuring that the it facilitates water holding and moisture dispersion. A detailed approach to soils on your project will help ensure a healthier plants and increased water holding capacity and moisture dispersion. Ultimately, this consideration results in less maintenance, plant replacement cost and water consumption. Proof: On our Diesel Technology Center project in Havre, Montana that recently achieved a 2-Green Globe rating, our consideration of the planting profile and physical properties played a key role in reducing outdoor water consumption by 30 percent. The soils were engineered in such a way to increase water dispersion and holding capacity, which reduced the need for the frequency and intensity of irrigation. Consideration #2: Vegetation Selection Description: While drought tolerance is the main goal for this project, it does not need to come at the expense of aesthetics. Roadside conditions are typically harsh, and selected plants must be tolerant of a variety of site conditions, including the climate, solar exposure and above- and below-ground conditions. Additionally, the plant selections need to be generally low-maintenance and organized to avoid difficult/dangerous maintenance situations. Strategy: Identify plant materials that require minimal soil volumes in order to achieve maximum health. Identify plant stock that are tolerant to magnesium chloride and other de-icing materials. Discuss with the client the realistic life span of plant materials. Consider the annual maintenance requirements for the plant stock (e.g. thinning, removal of dead flowers, pruning). Identify plant material with four season interests. Consider microclimate impacts such as snow drifting, snow plowing and solar exposure. Utilize plant material that is considered drought tolerant. Proof: As the city is making an increased effort to reduce water consumption, we have been able to integrate native and drought-tolerant plants into our palettes. The Ccara Building at Ferguson Farm is a design of ours demonstrating how aesthetic goals were achieved by providing color through the use of perennial plants. Due to the use of drought-tolerant plants, water consumption was reduced by 68 percent. In the I-25 Entryway Corridor Study in Casper, the recommendations for the placement of plant material took into consideration snow drifting and solar exposure. Tree placement must occur outside of the highway clear zone, and any massing of shrubs took into consideration the aspect, slope and surrounding improvements that could affect where snow will accumulate. Peaks to Plains DesignPC 3 Consideration #3: Safety Description: The overriding spatial deisgn considerations for roadway landscaping are those that address the safety of the corridor. The principle considerations are: visibility, clear zones, pedestrian safety and animal deterrence. No matter the design, sight lines must be preserved near intersections and driveways. The reflectivity or glare produced by materials should not distract drivers. Materials within the medians should visually contrast the roadway to assist drivers easily separate medians with driving lanes, particularly at night. Clear zones need to be maintained to provide a recovery area for the roadway. Pedestrian safety must also be considered at crosswalks, such as providing refuge areas on wider roadways. Finally, the design should reduce animal-vehicle conflicts by considering foliage that animals prefer, especially browsing species. Strategy: Urban roads have clear zone requirements as dictated by local agencies or follow the AASHTO’s “A Policy on the Geometric Design of Highways and Streets.” The FHWA also has resources regarding aesthetics and safety under “Context Sensitive Design” and “Roundabouts.” The combination of soft and hardscape materials at the approaches to intersections must account for traffic signage, visibility and geometric configurations. Proof: The aesthetic considerations for the Billings Airport Road project included berming the center of the roundabout in order to reduce headlight glare and to give drivers a visual cue that they will be maneuvering through the roundabout. At the Alkali Creek end of the project, a more native landscape treatment included the selection of specific grass species that did not attract antelope and deer, and wildflower plant materials could not attract avian species, due the proximity to the airport runway. Consideration #4: Maintenance Logistics Description: Long after the design and construction phase services are complete, the success of the installation relies on a systematic and integrated approach to maintenance. Maintenance success relies on both quality and quantity of the personnel and program. Maintenance personnel tend to have a high turn over rate and are often entry level jobs or maintenance is left to volunteer groups. Snow plowing and de-icing materials often migrate onto the medians, causing changes in soil chemistry or damaging plant material. Over Vegetation to deter browsing animals helps to reduce vehicle-animal conflicts. The Alkali Creek Interchange required clear zone setbacks, a specialty seed mix and a thoughtful compositon of planting soil in order to have vegetation survive without irrigation. The redesign for two traffic circles in Valley West proposes using non-living materials for aesthetics, while reducing water use and maintenance costs. Drought Tolerant Landscape & Irrigation Designs for City Medians4 time, the ease of maintenance outweighs the design decisions made due to life safety or technological factors, and ultimately the installation decays. Strategy: Include the anticipated maintenance personnel in the design review in order to identify any concerns related to maintenance. Discuss with the roads division the need for OSHA and lane closure requirements for personnel and equipment to access the medians. Design median edges to allow for road debris to accumulate and shed chemicals. Prepare a maintenance manual that outlines the design intent, the rationale for the design decisions made and the technical aspects that should be used in training. Identify a full- time city employee who is responsible for annual training on the maintenance for the system. Consider an annual contract with Peaks to Plains Design or another 3rd party to monitor irrigation consumption. Proof: Peaks to Plains Design designed the medians on the US Highway 93 South near the Stevensville Wye for the Montana Department of Transportation. The design took into account highway construction practices of extending pavement through the median, causing a drainage block. Our solution required the contractor use alternative construction methods where a deeper soil profile was necessary. An entryway median for the Bitterroot Heights Subdivision was technically dedicated as city park, but the city required the developer to maintain the median, who then allocated it to the HOA. The median was being over watered. Once the city parks department regained control, they were able to properly set the irrigation control clock and monitor the water use. Consideration #5: Irrigation & Clock Management (Smart Control) Description: While it is generally accepted that drip irrigation is the most effective delivery system to reduce water use, the strategy (e.g. surface versus subsurface), product selection, technology and clock management are critical to ensure the most efficient use of water. Pressure loss is also a critical issue in roadway design due to the length of pipe. The entry median to Bitterroot Heights Subdivision. Note how the sloped edges prevent debris from entering the planting bed and provides more soil volume for the ornamental trees. US Highway 93 South median cross section detail. Two planting soil profile depths allowed for woody plant stock root development and drainage from the center of the median. Peaks to Plains DesignPC 5 Have you ever seen an irrigation system running while its raining? Technology, such as rain sensors, shut off systems during rain events. (stock photo) This design for the Sidney Streetscape included rain gardens that were integrated into the curb to reduce the amount of storm water runoff and improve water quality. This would serve as the irrigation for the plant material in the garden, too. Strategy: We design using smart control technology that uses real-time weather data to increase water efficiency by reducing watering times and intensity. The smart control technology also provides the end-user with countless functions to assist in effect water management, as well as assists in maintenance of the irrigation system by helping to detect breaks. Proof: Our Northwest Pipe project in Billings achieved a 90 percent water use reduction, and it demonstrates how a combination of careful design, technology, soils and plants reduce water use. This project used drip irrigation that delivers water to the base of the plant, eliminating watering areas of the bed without plant material. The smart control technology allowed for the controller to make real- time adjustments based on the climate conditions present. Consideration #6: Stormwater Run-off & Median Drainage Description: Not all medians need to be at grade or raised. Some medians can be depressions that collect and detain storm water. A median depression (bioswale) must have the ability to quickly capture and hold runoff without erosion. The edge treatment of a median depression must be closely coordinated with city engineering, and the median often carries a series of important utilities. A bioswale or an at-grade median can reduce the amount of runoff and improve the water quality into the storm sewer system. Raised medians are often placed on top of asphalt pavement. Drainage from the vegetation becomes an issue from rain events and irrigation water. A subsurface drainage system should be integrated into the soil profile to allow for proper water holding capacity. Strategy: Peaks to Plains Design’s landscape architects and civil engineers will work with the city’s public works department to locate storm sewer and other utilities. We will perform storm water calculations that will help identify the intensity and duration of rainfall to properly size drainage infrastructure. In roundabouts and traffic circles, there are usually manholes placed where a grade should be raised. We consult OSHA requirements and city standards to determine of a manhole can have its rim raised. Proof: Peaks to Plains Design did a streetscape design for the City of Sidney. The four-block area did not have any existing storm sewer infrastructure. We designed rain gardens into the curb line of the project. The gardens consisted of a planter “vault” that encompassed three levels of water detention and treatment. Overflow was allowed from the vault to continue flowing water towards the end of the block. Drought Tolerant Landscape & Irrigation Designs for City Medians6 Airport Road Billings, Montana Peaks to Plains Design was the project landscape architect for a highway reconstruction project for Montana State Highway 3, locally known as Airport Road. City leaders considered this 3-mile corridor as one of the gateways to the city. Peaks to Plains Design worked with the project engineers to implement context-sensitive design considerations. The project starts at the entry to the Billings Logan Airport, with a multi-lane roundabout. The landscape architect worked with the Airport authority to develop an aesthetically pleasing site entry through landscape enhancements, planning for future signage and careful selection of plant material that does not conflict with the wildlife mitigation requirements for airports. In addition, the landscape architect designed an efficient irrigation system that tied into the large system supplied by the airport. The design considerations for the new multi-lane roundabout took into consideration the FHWA standards, clear-zone requirements and long-term maintenance considerations. The landscape architect specified the multiple levels of native grass re-vegetation and soil amendment profiles. The anchor end of the project included a new interchange with Alkali Creek Road. Peaks to Plains Design incorporated native sandstone boulders to recreate the vertical element and provide a means for modified soil structure to support the re-vegetation of trees and shrubs native to the area. In addition, the landscape architect research and provided recommendations on the architectural concrete finishes for retaining walls, bridge abutments and other features. The construction value for Peaks to Plains Design’s scope of work is approximately $1.2 Million. Featured Project Experience Peaks to Plains DesignPC 7 Downtown Image Enhancement Sidney, Montana Peaks to Plains Design prepared streetscape plans for the community of Sidney, Montana. Downtown businesses owners were interested in developing event spaces and enhancing the streetscape facade with landscape augmentations and site furniture. Each concept took into consideration the function of the existing businesses on Main Street, traffic calming techniques, opportunities for outdoor patios and public gathering spaces. Of particular interest was the potential reconfiguration of the courthouse front lawn. Other projects affecting the concepts included additions to the County’s justice center, library and an adjacent MDT project. Peaks to Plains Design developed several concepts for the reconfiguration of parking and provided graphic illustrations for use as a communication tool to help Sidney residents visualize and market the plan. Construction document preparation for this streetscape enhancement project was completed in 2014. The 4-block project consisted of modifying the existing downtown Main Street corridor to provide for streetscape enhancements, alternative storm water collection and treatment measures, street lighting, sidewalk and ADA pedestrian ramp improvements, landscaping, irrigation and roadway rehabilitation. As part of this project, the existing roadway geometry was evaluated and narrowed to provide for parallel parking and an innovative landscape enhancement design that serves as both aesthetic improvements as well as providing storm water collection, treatment and detention facilities to help correct existing drainage issues. The plant material selected provided both a functional and aesthetic component, including the filtering of storm water. Once the rain gardens were inundated, the remaining water would run to the storm water piping system, which was already in place. The pre-treatment and use of storm water will help with capacity issues in the existing system. In addition, the use of green streets would not require an irrigation system installation, reducing project costs and long-term maintenance. Drought Tolerant Landscape & Irrigation Designs for City Medians8 I-25 Entryway Corridor Study Casper, Wyoming The Casper Area MPO consists of the City of Casper, Towns of Evansville, Bar Nunn and Mills, Natrona County and the Wyoming Department of Transportation. Historically, Casper has been a regional hub of energy activity with oil refineries, railway and trucking depots and secondary industries supporting the energy sector. Development was loosely controlled along major thoroughfares, resulting in blighted areas along the I-25 corridor as the boom and bust cycle of energy production affected the region. The primary objective of the project provides a policy document for shaping the Interstate corridor into a visually appealing and cohesive gateway into the community. Eleven interstate interchanges, overpasses and underpasses were evaluated as a part of the study. The resulting design guidelines for improvements within the rights- of-way for I-25 provides project designers with the tools to apply design standards to new construction and renovation projects. The plan examines visual improvements that reflect the latest trends in highway safety, landscape design and structural improvements. Peaks to Plains Design facilitated three community listening sessions, utilizing the latest technology in public participation. The research included factors that affect the design such as viewshed analysis, microclimate, clear zones and non-motorized transportation issues. The resulting design guidelines focused on structural bridge elements, regulatory, warning and guide signs, way finding signs, lighting and landscaping. Maintenance considerations were a critical component of the plan. The team developed conceptual designs for each of the eleven study areas, including plan view renderings and visual simulations that depict both creative and functional solutions. A section of the plan focused on policy considerations such as zoning and site development regulations, preservation of views and property/ business owner incentives. Top: Highway median existing. Bottom: Median after (visual simulation). Synthetic grass and a highway rated cable rail barrier are two solutions to improve an otherwise weed infested median with no access to maintenance or irrigation.
