What is the FNGLA recommendation for using drains in landscapes?

The FNGLA recommends using drains in landscapes primarily to effectively manage stormwater and reduce erosion. Proper drainage systems are crucial in directing excess water away from areas where it can accumulate, thus preventing flooding and minimizing soil erosion. When stormwater is managed well, it helps to protect the integrity of the landscape, supports plant health by preventing waterlogging, and reduces run-off that can carry pollutants into local waterways. This approach not only enhances the functionality of the landscape but also promotes sustainability by preserving ecological balance. Other options focus on aesthetics or negative outcomes, which do not align with the primary goal of effective landscape management concerning drainage.
