Efforts to incorporate green infrastructure in urban landscapes are growing across the Chesapeake Bay watershed. Local governments are increasingly investing in rain gardens, permeable pavements, green roofs, bioswales, and other practices to decrease flooding and improve water quality. Although trees also provide stormwater benefits, expanding tree canopy in the urban environment is not always identified as a priority. Lancaster City in Pennsylvania serves as an exceptional example of a jurisdiction promoting tree canopy in an effort to augment green infrastructure and improve local water quality.
