DRAINAGE FACILITIES

Includes gutters, swales, pipes, conduits and superstructures for the collection and conducting of stormwater to an adequate facility for the storage and disposal of the stormwater.

GROUNDWATER TABLE

The elevation of the top of the water stored in the highest aquifer in the subsoils, at the location of the proposed structure, including but not limited to so-called "perched water," except that where it is demonstrated that removal of the impervious layer underlying the perched water will substantially lower the level of the water, the lower water surface shall be considered the groundwater table. In locations where the groundwater is subject to tidal action, the mean high elevation of the groundwater surface shall be considered the groundwater table.

LATERAL SUPPORT

The resistance to active horizontal pressure of soils provided by either the passive pressure of the adjoining soils or by a retaining wall or structure.

NATURAL DRAINAGE

The stormwater runoff resulting from topographical and geographical surface conditions prior to clearing, regrading or construction.

REGRADE

To change the elevation of the ground surface, either temporarily or permanently.

STABILIZATION

Treatment of subsoils to increase ability to resist lateral pressures and/or treatment of surface to resist wind and water erosion.
