The landscape design character of the proposed roadway improvements project for Happy Valley Road from Pima Road to Alma School Road has a Sonoran “Southwest Arid” desert theme emphasizing transparency in the planting design. This theme is influenced by existing native desert plants and inert materials along both sides of Happy Valley Road and the surrounding native Sonoran Southwest desert plant material and abundance of natural inert materials found in the adjacent slopes of the McDowell Mountains—particularly the array of angular fragmented “Desert Pavement” of indegenous brown sandstone formations. The landscape design will include Low Impact Development (LID) best stormwater managemnt practices. The project’s native desert plant palette includes trees, shrubs and cacti which are grouped and arranged to create a natural native desert landscape matching surrounding undisturbed plant material with a commitment to sustainability and water conservation. The primary trees are Desert Ironwood and Foothill Palo Verde supported by shrubs, cacti and accents native to Arizona’s intermediate desert characterized by gray-green foliage, varied textures, and rich, vibrant flower colors. Disturbed or unvegetated areas within the project limits will have a hydroseed application of a specified native seed mix applied. All plant material is listed on the Arizona Department of Water Resources low water use drought tolerant plant list and is in compliance with the City’s Design Guidelines with specific attention to Scottsdale Sensitive Design Principles. Sustainability principles will be integrated in the landscape design reflected in the use of salvaged and relocated native plants and selective use of angular crushed decomposed granite “Desert Pavement” used as ground plane surfacing materials.

The landscape design character of the proposed roadway improvements project for Happy Valley Road from Pima Road to Alma School Road has a Sonoran “Southwest Arid” desert theme emphasizing transparency in the planting design. This theme is influenced by existing native desert plants and inert materials along both sides of Happy Valley Road and the surrounding native Sonoran Southwest desert plant material and abundance of natural inert materials found in the adjacent slopes of the McDowell Mountains—particularly the array of angular fragmented “Desert Pavement” of indegenous brown sandstone formations. The landscape design will include Low Impact Development (LID) best stormwater managemnt practices. The project’s native desert plant palette includes trees, shrubs and cacti which are grouped and arranged to create a natural native desert landscape matching surrounding undisturbed plant material with a commitment to sustainability and water conservation. The primary trees are Desert Ironwood and Foothill Palo Verde supported by shrubs, cacti and accents native to Arizona’s intermediate desert characterized by gray-green foliage, varied textures, and rich, vibrant flower colors. Disturbed or unvegetated areas within the project limits will have a hydroseed application of a specified native seed mix applied. All plant material is listed on the Arizona Department of Water Resources low water use drought tolerant plant list and is in compliance with the City’s Design Guidelines with specific attention to Scottsdale Sensitive Design Principles. Sustainability principles will be integrated in the landscape design reflected in the use of salvaged and relocated native plants and selective use of angular crushed decomposed granite “Desert Pavement” used as ground plane surfacing materials.
