The firm’s innovative environmental designs are inspired by broader natural and cultural landscape elements and processes. At the regional scale, O2’s approach includes the identification of Green Networks of important landscape patterns as well as the identification of natural assets that deliver vital ecosystem goods and services. At the urban scale, low impact development techniques and sustainable urban watershed management figure prominently in the firm’s work. At the local and site scale, innovative stormwater collection systems, rain gardens, bio-swales, and numerous other green technologies aid the creation of sustainable landscapes.
