Mr. Allen also has over 17 years of landscape technical advisory experience, working with public agencies and private clients to formulate landscape guidelines that conform to water conservation ordinances, grouping appropriate plantings per WUCOLS (Water Use Classification of Landscape Species), maintenance guidelines, design using native plants, water conservation, analysis of water efficient irrigation equipment, water management, central control system conversion, water audits, and water demand analysis.


Mr. Allen has significant experience in preparing irrigation point of connection master plans, demand analyses, hydraulic analyses and coordinating this information with multi-disciplinary teams in both the public and private sector.


As a child Brett used to help his parents with landscaping projects around the house and he also enjoyed helping his grandpa in the vegetable garden.  He took an immediate interest in plants, how they developed and grew (or didn’t). As Brett grew older he became responsible for caring for their many fruit trees and large property, furthering his interest in plants and the landscape. 

When he started high school, Brett soon joined the Future Farmers of America (FFA) and began competing in plant identification and landscape design against teams from around the state.  Students were encouraged to practice their skills in a real world environment, so he started a small business designing and installing landscapes for the many new tract homes popping up around his school.


Brett says he owes much of his success in this field to the initial experience that FFA provided, and he eventually earned various scholarships which ultimately paid for his attendance at Arizona State University and his degree in Landscape Architecture. Landscape architecture has become very important to him because he enjoys making outdoor spaces work for people, creating a sense of place and adding value to them, as well as promoting water and energy savings through well designed landscapes.
