A Great Alternative for Borough Residents! - Impervious vs Pervious Pavement Material

IMPERVIOUS VS. PERVIOUS PAVEMENT/ MATERIALlogo

There are two primary types of pavement: pervious and impervious. Previous
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
the paved surface at particular intervals.

DISADVANTAGES OF IMPERVIOUS PAVEMENT:

The number one contributor to urban flooding is impervious surfaces. Concrete and
asphalt do not absorb water and instead create runoff from flash flooding from
stormwater during rain events. Stormwater runoff floods streets then move 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 previous 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
