What is permeable paving?

Permeable paving refers to hardscape surfaces designed to allow water to pass through and drain into the soil beneath, rather than running off into storm drains or flooding low spots. In the Charlotte area, where stormwater management is increasingly regulated under local ordinances, permeable surfaces help properties meet required retention standards while still providing functional walkways, driveways, and patios.

Common permeable paving options include permeable pavers (concrete or stone units set with open joints), porous concrete or asphalt that contain voids for water infiltration, and gravel or aggregate pathways. Each type offers different durability and aesthetics, and the choice depends on intended use, soil conditions, and design goals.

Permeable paving serves multiple purposes in landscape design. It reduces the volume and velocity of stormwater runoff that can erode landscapes or overwhelm municipal systems. It also allows groundwater recharge, helps filter pollutants naturally, and reduces heat island effects compared to solid impervious surfaces. Many Charlotte-area properties are incorporating permeable surfaces into new construction or renovation projects to comply with stormwater codes while improving site drainage and environmental performance.

Landscape designers familiar with local stormwater requirements can specify and install permeable paving to meet both regulatory needs and client site conditions.
