Cheryl Corson draws on decades of design and management practice to present the broadest framework within which landscape property managers, contractors, and design professionals may create customized, site-specific sustainable landscape maintenance plans.

Many resources exist offering guidance on maintaining Stormwater BMPs (best management practices), but nothing on how to sustainably manage properties so that design intent, historic resources, the regulatory environment, and worker safety are also accounted for. This manual supports a new communication paradigm between designer, contractor, and client which places the landscape itself at the forefront of maintenance decisions.

With financial and in-kind support from the District of Columbia Department of Energy & Environment, the Chesapeake Conservation Landscaping Council, the Low Impact Development Center, and the Maryland Sea Grant College, this manual was written to serve as the maintenance reference for the Chesapeake Bay Landscape Professional (CBLP) voluntary certification program.
