Trees assist in stormwater management by slowing the rate at which rainfall reaches the ground through canopy interception and improving soil absorption. Planting new trees helps to conserve and enhance our existing tree canopy. Increased tree canopy coverage can slow runoff rates and reduce stress on the stormwater infrastructure system by reducing peak flows.
Tree selection should be appropriate for the planting site. Standards for shade tree planting, including a list of suggested varieties can be found here, under the Shade trees section.
