Kitiyepumú Park, which translates to “Our Playing Place,” was chosen by the Santa Ynez Band of Chumash Indian’s children as a very fitting name for their beloved park. Wallace Group Landscape Architects and Civil Engineers collaborated to design the park with the environment in mind using locally sourced materials, native vegetation and recycled water generated from the Tribe’s water reclamation facility. Despite the park’s challenging location on a long narrow slope, our skilled team was able to modify the terrain to maximize useable area capable of accommodating a variety of recreational uses to serve in promoting the health and well being of the community.   #wallacegroup #thisislandscapearchitecture #wlam2019 #WLAM2019!

A main goal for many home owners is that their space embody their unique personality, needs and style. Wallace Group landscape architects worked closely with interior designers at Trilogy Monarch Dunes Model Homes in Nipomo, California, to develop eight distinctive design styles and layouts to represent the wide variety of housing options available in the community. The overall model park layout was led by our landscape architect through multiple concept sketches and discussions with client representatives.   #WLAM2019! #wallacegroup #wlam2019 #landscapearchitecture #ASLA #community #housing #design #style #modelhomes #sanluisobispo #nipomo #professionalservices

A space designed with intention and collaboration feeds community connectivity and a defined sense of place. Trilogy Monarch Dunes Model Homes does just that, nestled in Nipomo's eucalyptus tree forest and Monarch Butterfly preserve on California's Central Coast. This remarkable facility took form with early collaboration and commitment from the design team to honor the monarch butterfly and celebrate the natural beauty of the site.   #wlam2019 #WLAM2019! #landscapearchitecture #wallacegroup #centralcoast #thisislandscapearchitecture  #ASLA

April is World Landscape Architecture  Month! One of our favorite projects is the new terminal at the San Luis Obispo County Airport. The outdoor courtyard was designed to provide a sense of calm, as well as provide a preview of the regional landscape, unique to San Luis Obispo. The most impressionable regional features, when flying, driving or hiking in San Luis Obispo, are undeniably, the Nine Sisters. These ancient volcanic peaks also referred to as “Morros,” rhythmically march from the coast of Morro Bay and into the City of San Luis Obispo.

The Society of Civil Engineering Students at Cal Poly SLO hosted 17 colleges on campus for the Pacific Southwest Regional Conference last weekend.  This engineering conference included 19 different engineering and non-engineering events, including the concrete canoe, which was held out at Lake Nacimiento.  Wallace Group is a proud supporter of SCE and Cal Poly and was excited to assist the Cal Poly Planning Team in whatever capacity needed. Principal Engineer, Steve Tanaka assisted the Cal Poly Planning Team with their emergency response planning for the concrete canoe race at Lake Nacimiento, while engineers Sarah Huffman and Wyatt Banker-Hix judged the Transportation Project and Principal, Kari Wagner judged the Environmental Project.  Sarah and Wyatt also represented ASCE at the Concrete Canoe races on Friday answering questions and promoting the students involvement in the national organization.  It was exciting to see the students not only plan the entire event, but to also compete in each of the events at a high level. Cal Poly SLO took first place overall, while UCLA finished second and Cal State Fullerton finished in third.
