Background/Location

Rainwater and snow melt runs off the surface of traditional pavement and carries pollutants to our water ways. Porous pavement lets water infiltrate into the soil through gaps in all the layers to the groundwater. It also filters pollutants from stormwater and helps protect the water quality of Mill Brook. Since optimum performance of porous pavement depends on these air spaces, sand should not be used in the winter. Porous pavement must be vacuumed (not swept) clean to avoid clogging. Watch the video below to learn more about the porous pavement project on Hurd Field.

Benefits of Porous Pavement

• Reduces the volume and velocity of runoff
• Improves water quality by capturing the water and filtering it
• Replenishes groundwater
• Reduces impacts of flooding during storm events
• Eliminates the need for sanding and reduces the need for road salt in winter months
