ARNOLD ASSOCIATES, landscape architects and site planners established in Princeton & Trenton, NJ in 1971 by Henry Arnold (emeritus), has executed over 900 commissions. The Firm's work covers a wide range of site conditions and client needs in the United States and abroad. Our disciplines cover a range of services, including site layout, irrigation, drainage design, vehicular and pedestrian circulation, grading, and planting design. The Firm specializes in urban tree planting techniques for sustainable urban street trees. These disciplines have been applied in the context of urban spaces, parks, commercial, mixed-use developments, residential, retail, institutional, and civic projects.
The office is a partnership organized to allow the Principal's involvement from conceptual design through project completion. The policy of maintaining highly trained in-house staff and associating with the best specialist consultants has proven an effective way to secure both operational efficiency and design excellence.
Past commissions vary in scale and complexity, ranging from major open spaces and memorials on the Washington, DC Mall, to the more restrictive design for a small interior plaza in Rockefeller Center, Manhattan. The large number of these projects that have been built and their durability provide a measure of the firm's effectiveness as rigorous professionals and artists.
