Since 1945, Walter L. Phillips, Inc., has been providing land development engineering services throughout the Washington D.C. metropolitan area. We use our in-depth experience and knowledge to provide high-quality services to our clients to ensure that projects are successfully completed. Our staff of highly-qualified engineers, planners, land surveyors and landscape architects is dedicated to helping transform our clients goals into economically-sound and visually-creative projects.

Over the years, we have developed a broad range of land development engineering experience on a variety of projects, including government, institutional, residential, office, commercial, adaptive reuse, residential infill and mixed-use projects. Through our projects, we have developed long-standing relationships with the Washington D.C. metropolitan area municipalities. It is through these relationships that we are able to work cooperatively with the review agencies to help our clients projects move efficiently through the site plan and zoning processes.

We have also gained valuable experience in low impact design, including the design of innovative stormwater management and site design to meet LEED criteria. We offer comprehensive land development engineering services to assist our clients in all aspects of the land development process, including preliminary feasibility analysis, zoning assistance, site plan approval and construction consultation and as-built services.

With our extensive experience in the Metro DC area, we pride ourselves on bringing outstanding results to everything we do. We work diligently to recognize key aspects of our clients needs and provide clear alternatives in a responsive manner. We work to anticipate changes before they happen, and help clients and employees adapt to those changes.
