  2. Impervious surface - Wikipedia

    en.wikipedia.org/wiki/Impervious_surface

    Impervious surface percentage in various cities. The percentage imperviousness, commonly referred to as PIMP in calculations, is an important factor when considering drainage of water. It is calculated by measuring the percentage of a catchment area which is made up of impervious surfaces such as roads, roofs and other paved surfaces.

  3. Urban runoff - Wikipedia

    en.wikipedia.org/wiki/Urban_runoff

    As stormwater is channeled into storm drains and surface waters, the natural sediment load discharged to receiving waters decreases, but the water flow and velocity increases. In fact, the impervious cover in a typical city creates five times the runoff of a typical woodland of the same size. [9] [clarification needed]

  4. Surface runoff - Wikipedia

    en.wikipedia.org/wiki/Surface_runoff

    Surface runoff often occurs because impervious areas (such as roofs and pavement) do not allow water to soak into the ground. Furthermore, runoff can occur either through natural or human-made processes. [1] Surface runoff is a major component of the water cycle. It is the primary agent of soil erosion by water.

    Surface water flooding is especially dangerous for cities with a high proportion of impervious soil coverage and hard surfaces—such as roads and parking lots—that prevent rainwater from being ...

  6. Permeable paving - Wikipedia

    en.wikipedia.org/wiki/Permeable_paving

    Permeable pavement surfaces may be composed of; pervious concrete, porous asphalt, paving stones, or interlocking pavers. [1] Unlike traditional impervious paving materials such as concrete and asphalt, permeable paving systems allow stormwater to percolate and infiltrate through the pavement and into the aggregate layers and/or soil below. In ...

  7. Stormwater fee - Wikipedia

    en.wikipedia.org/wiki/Stormwater_fee

    A stormwater fee is a charge imposed on real estate owners for pollution in stormwater drainage from impervious surface runoff.. This system imposes a tax that is proportional to the total impervious area on a particular property, including concrete or asphalt driveways and roofs, that do not allow rain to infiltrate.

  8. Urban flooding - Wikipedia

    en.wikipedia.org/wiki/Urban_flooding

    Any activities that enlarge the impermeable surface areas in a city can increase the flood risk. Impermeable surface areas are generated through soil sealing as this reduces drainage options of floodwaters. [3]: 925 As the pace of urbanization accelerates around the world, urban flooding has the potential to affect more people. [3]: 925
