What is meant by "Post-Construction Stormwater Management"?

Post-Construction Stormwater Management refers to the strategies and practices that are implemented to manage stormwater runoff after a construction project has been completed. This phase is critical because it aims to mitigate the impacts of increased impervious surfaces and changes to the landscape that can lead to elevated volumes of stormwater runoff.

Effective post-construction management includes solutions such as installing retention and detention basins, incorporating bioretention systems, utilizing green roofs, and ensuring that proper landscaping is established to manage water flow. The goal is to control the quality and quantity of stormwater discharges and to prevent flooding, erosion, and pollution of water bodies after the site is operational.

The other options do not accurately represent post-construction stormwater management. Measures taken before construction pertain to pre-construction planning, maintenance activities during construction relate to ongoing management during the building process, and plans for sediment control during demolition refer to activities aimed at controlling sediments before construction activities begin. These aspects focus on different phases of a project, while post-construction specifically addresses the management of stormwater following the completion of construction activities.
