This study was releasing water. This study was undertaken to assist Jacksonville in undertaken to assist Jacksonville in evaluating how to better integrate evaluating how to better integrate trees into their stormwater trees into their stormwater management programs. More management programs. More specifically, the study covers the role specifically, the study covers the role that trees play in stormwater that trees play in stormwater management and shows how the city management and shows how the city can benefit from tree conservation can benefit from tree conservation and replanting. It also evaluates ways and replanting. It also evaluates ways for the city to improve forest for the city to improve forest management as the city develops. management as the city develops.
