Welcome to the UNHSC-NEMO Innovative Stormwater Management Database!

This searchable and amendable database is designed to highlight innovative BMP strategies, such as Low Impact Development (LID) designs, implemented throughout the state and region. LID design originated in Maryland in the 1990's to reduce the negative impacts of traditional development on watershed areas and receiving waters. The goal of LID is to limit generation of runoff from developed areas and preserve the natural or predevelopment hydrology of a site. Bioretention areas, rain gardens, gravel wetlands, and pervious pavements are some of the innovative stormwater best management practices (BMPs) that can be designed to mitigate the adverse impacts impervious surfaces.

This database consists of an interactive map showing the locations of various BMPs around the state. Clicking on a town will return information from a database about LID practices in that town. A link to a one-page document (pdf) with more detailed information such as the installation date, installer, and engineer will also appear. There is also a unique update feature that allows users familiar with additional LID installations to add regional examples to the database. We hope that these tools can demonstrate real world examples of successful innovative BMP installations throughout the region. Lack of performance data or implementation examples is often the limiting factor of more widespread acceptance and use of innovative stormwater BMPs. We hope this information is useful for anyone who wants to start using these innovative techniques to protect our water resources!
