As autumn paints our neighborhoods with brilliant foliage, the seasonal leaf drop brings more than just beauty — it brings responsibility. Crisp, fallen leaves may seem harmless scattered across your yard, but when left unchecked, leaves and other yard waste like grass clippings, dead foliage, twigs, and branches that are not properly bagged or contained can pose unique challenges in a city like ours.

During rainfall, a city’s many hard, paved surfaces cause stormwater to flow quickly. When yard waste is swept into the streets, it collects on the top of storm drains where it can block the flow of water through the grate. Because storm drains are not designed to convey physical debris, this can cause water to back up, contributing to the risk of localized flooding in streets and wet basements. These mats of debris can also begin to trap additional items like litter, worsening the problem.

Large quantities of decomposing leaves also release nutrients into stormwater, which then flows into nearby waterways and can trigger algae blooms that may alter local water chemistry. This can negatively impact fish and other wildlife.

Regular yard maintenance during the fall isn’t just about curb appeal, it’s a frontline defense against water pollution. You can play a vital role in protecting our community and waterways by taking extra precautions while maintaining your yard this fall.
