The term "retrofit" in the context of stormwater systems refers to the process of modifying existing infrastructure to enhance its performance and accommodate new best management practices (BMPs). This approach is crucial for improving the functionality of older systems that may not meet current environmental or regulatory standards.

When retrofitting, engineers and planners aim to adapt the existing systems to address contemporary challenges, such as increased stormwater runoff due to urbanization, climate change impacts, and the need to meet modern water quality standards. This can involve the installation of new features, such as bioretention areas, permeable pavements, or additional detention facilities, which can work in concert with the existing system rather than replacing it entirely.

In contrast, other options suggest alternate actions. Removing outdated systems entirely would not necessarily improve the overall effectiveness or sustainability of stormwater management and could lead to disruption and increased costs. Constructing new facilities from scratch does not align with the concept of retrofitting, which focuses on improving what is already there. Assessing systems for compliance is an important practice, but it does not involve modifying them, which is the core idea behind retrofitting. Therefore, the focus of retrofitting is specifically on enhancing and integrating new practices into existing systems for
