Trees at Work: Natural Stormwater Solutions

The original tree planted on Arbor Day 2025 that led the initiative to apply for Tree City status.

As Arbor Day and Earth Day approach, it is a good time to reflect on the important role trees play in our community. In addition to their beauty, trees provide essential environmental benefits.

During a rainfall, trees act as natural umbrellas. Their leaves and bark capture and hold water, slowing the rate at which it reaches the ground. Depending on the size and species, a single tree can store 100 gallons or more of water before becoming saturated. Across a community, this adds up quickly.

This process, known as stormwater interception, helps reduce runoff by an estimated 2 to 7 percent annually. When combined with natural landscaping, that reduction can be even greater – sometimes managing most or all rainfall on site. By slowing and absorbing water, trees help limit flooding, reduce strain on drainage systems and lower long-term infrastructure costs.

Tree roots also play a critical role below the surface. They stabilize soil, filter pollutants and help recharge groundwater, which supports drinking water supplies for many communities.

Planting and maintaining trees are simple and powerful ways to protect our environment and support long-term sustainability. This Arbor Day, consider how even one tree can make a meaningful difference.
