Impervious surfaces definition

Impervious surfaces means those areas which prevent or impede the infiltration of stormwater into the soil as it entered in natural conditions prior to development. Common impervious areas include, but are not limited to, rooftops, sidewalks, walkways, patio areas, driveways, parking lots, storage areas, compacted gravel and soil surfaces, awnings and other fabric or plastic coverings.

Impervious surfaces means any hard surface that prevents or hinders the absorption of water into the soil, or that causes reduced quality of runoff water, or causes water to runoff in greater quantities or at greater flow rates than the natural surface.

Impervious surfaces means hard-surfaced areas which prevent or retard the entry of water into the soil mantle and/or cause water to run off the surface in greater quantities or at an increased rate of flow than under natural conditions. Common impervious surfaces include, but are not limited to, rooftops, concrete or asphalt roads, sidewalks and paving, walkways, patio areas, driveways, parking lots or storage areas and gravel, hard-packed dirt, oiled or other surfaces which similarly impede the natural infiltration of surface water or runoff patterns existent prior to development.

Examples of Impervious surfaces in a sentence

• Impervious surfaces are defined as material that does not allow water to percolate into the soil on the Protected Property, including, but not limited to, buildings with or without flooring, paved areas, and any other surfaces that are covered by asphalt, concrete, or roofs.

• Impervious surfaces are defined as material that does not allow water to percolate into the soil on the Protected Property, including, but not limited to, buildings, with or without flooring, paved areas, and any other surfaces that are covered by asphalt, concrete, or roofs.

• Impervious surfaces include concrete unless unsealed cracks or holes are present.

• Impervious surfaces also include building foundations, porches, decks, patios, sidewalks, play courts (tennis, basketball, etc.), pools, and other improvements that impede the absorption of water.

• Impervious surfaces shall include pavement, buildings, public and private roadways, and all other surfaces with similar runoff characteristics.

More Definitions of Impervious surfaces

Impervious surfaces means those surface areas which either prevent or retard saturation of water into the land surface and cause water to run off the land surface in greater quantities or at an increased rate of flow from that present under natural conditions preexistent to development. Examples of impervious surfaces include, but are not limited to, rooftops, concrete or asphalt sidewalks, walkways, patio areas, driveways, parking lots or storage areas and gravel, oil, macadam, or other surfaces which similarly impact the natural saturation or runoff patterns which existed prior to development.

Impervious surfaces means those areas of a lot or development covered by roofs, terraces, outside balconies, canopies, or paved surfaces such as driveways, sidewalks, courts, streets, or parking areas. A surface paved with an accepted asphalt or other acceptable material which, after compaction, is not thicker than one and one-half inches shall not be considered impervious, provided such surface will pass an amount of water equivalent to one- half inch of rainfall per hour and is underlaid by permeable soil;

Impervious surfaces means a constructed surface such as sidewalks, roads, parking lots or driveways covered by water impenetrable materials such as asphalt, concrete, brick, pavers, stone and/or highly compacted soils.

Impervious surfaces means those areas that prevent or impede the infiltration of stormwater into the soil as it entered in natural conditions prior to development. Common impervious areas include, but are not limited to, rooftops, sidewalks, walkways, patio areas, driveways, parking lots,

Impervious surfaces means areas that do not allow significant amounts of water to penetrate.

Impervious surfaces means a hard surface area which either prevents or retards the entry of water into the soil mantle, and/or which causes water to run off the surface in greater quantities or at an increased rate of flow from the flow present under natural conditions prior to development.

Impervious surfaces means those surfaces, improvements and structures that cannot effectively infiltrate snow melt and stormwater into the ground, including but not limited to: parking areas, driveways, streets, sidewalks, areas of concrete, asphalt, gravel or other compacted aggregate, swimming pools, and areas covered by the outdoor storage of goods or materials which do not absorb water.
