IMPERVIOUS VS. PERVIOUS PAVEMENT/ MATERIAL There are two primary types of pavement: pervious and impervious. Pervious pavement is designed to let water naturally seep through it and go down into the soil beneath. Impervious pavement does not allow water to seep through it. Instead, with impervious pavement, water runs off into storm drains that are lined along the road or paved surface at particular intervals. DISADVANTAGES OF IMPERVIOUS PAVEMENT: The number one contributor to urban flooding is impervious surface. Concrete and asphalt do not absorb water and instead create runoff from flash flooding from stormwater during rain events. Stormwater runoff floods streets then moves into homes and businesses creating extreme flood damage and safety hazards. Drainage systems for impervious surfaces can quickly get overcome and overwhelmed by heavy rain as they have limited inlets and storage capacity. THE BENEFITS OF PERVIOUS PAVEMENT • Promotes infiltration of stormwater • There are many pervious surface and paving material choices • Paver systems are easy to repair or replace • Slows stormwater runoff • Helps clean the stormwater through filtering it through the base material and soil • Beneficial to street trees as roots can have more access to air and water • Pavers enhance curbside appeal and increase property value • Groundwater recharge where soils and geologic conditions allow NOTE; ANY QUESTIONS CONTACT ROBERT LAWSON, ZONING OFFICER AT 908 259-3023 OR EMAIL: [email protected].
