Low-Impact Development: How LID Works in Different Regions


While Low-Impact Development (LID) practices are often presented as a ‘cure-all’ for stormwater programs, regional climatic differences greatly impact the effectiveness of LID in reducing stormwater runoff. As such, a LID practice that works well in the Southeast may not be the best solution in the Northwest. So…are you implementing the correct LID practice for your climate?

Join returning speaker Doug Beyerlein, P.E., P.H., D.WRE, as we discuss the different types of LID (impervious area disconnection, rain gardens, bioswales, bioretention, permeable pavement, and green roofs), and how each type of LID works in varying climates to reduce stormwater runoff. Long gone are the days when only adding a rain garden would make your stormwater problems disappear. Understanding the effectiveness of a specific LID practice in your region is critical to selecting the best solution to solve a site-specific stormwater problem.

In this online training webinar, we’ll discuss climatic conditions that impact LID effectiveness in all four regions of the country: Mid-Atlantic, Southeast, Southwest, and Pacific Northwest. First, we’ll overview the different LID practices and how they each reduce stormwater runoff. We’ll then explore computer modeling results for each of the four climatic regions to determine how different LID practices perform and why certain LID practices excel in specific environments. We’ll wrap up by discussing LID design, including the most important factor in reducing stormwater runoff: the native soil infiltration rate.
