Rock Design Associates LLC was established with the foundational commitment that we will deliver beautiful, dynamic, innovative, and responsible design strategies for our clients. With a broad range of public and private clients our landscapes are imagined with a deep understanding and appreciation of each site’s heritage, a respect for the natural environment, and a recognition of the social context in which they exist. Our approach to landscape architecture, environmental planning, and design relies on collaboration within our own practice as well as the collaboration with our clients, our colleagues, and our consultants. We find that it is through the innate complexity of place and the multilayered influences on those places that we understand a site’s unique history, nature, and cultural value. RDA also believes deeply in the element of time as a key driver of any design and that our work is elevated by the enduring commitment of those who steward and maintain these creations now and into the future.
