Shadley Associates is a Lexington landscape architecture firm established in 2003 and led by principals JP Shadley and Pamela Shadley. The firm says it works on landscape architecture, site planning, and urban design for public, institutional, commercial, and residential projects. Its work reaches beyond a typical residential yard: a 2007 project report identified JP Shadley and Pamela Shadley as landscape architects leading the design of a garden with marble and granite features, and a later report named the firm as landscape architect for a Massachusetts project. The company also says it is woman-owned, WBE certified, and DBE certified. Before hiring, confirm whether the engagement covers design only or also construction coordination, and ask for comparable examples, schedule, and budget responsibilities. BBB lists the firm as not rated, while Google shows four stars from two ratings; those figures provide little customer review history. Shadley Associates appears suited to clients seeking formal landscape architecture, site planning, or urban design for a complex property or public project. Ask which principal will lead the work and what services continue through construction and maintenance.
