Best Management Practices," (as a reference for BMP's) and the Minnesota Department of Transportation's, "Erosion Control Design Manual.") 3.012 Buffer A vegetated area, including, native trees, shrubs and grassy vegetation, that exist or was established to protect a water of the state. Alteration of such areas is strictly limited. 3.013 Developer A person, firm., corporation, sole proprietorship, partnership, state agency, or political subdivision thereof engaged in a land disturbance activity. 3.014 Discharge The conveyance, channeling, runoff, or drainage, of storm water, including snowmelt, from a construction site. 3.015 Energy Dissipation This refers to methods employed at pipe outlets to prevent erosion. Examples include, but are not limited to; aprons, riprap, splash pads, and gabions that are designed to prevent erosion. 3.016 Erosion Any process that wears away the surface of the land by the action of water, wind, ice, or gravity. Erosion can be accelerated by the activities of people and nature. 3.017 Erosion Control Refers to methods employed to prevent erosion. Examples include soil stabilization practices, horizontal slope grading, temporary or permanent cover, and construction phasing. 3.018 Erosion and Sediment Practice Specifications or Practice The management procedures, techniques, and methods to control soil erosion and sedimentation as officially adopted by the either the city, county or local watershed group, whichever is more stringent. 3.019 Exposed Soil Areas All areas of the construction site where the vegetation (including trees, shrubs, and brush) has been removed. This includes topsoil stockpile areas, borrow areas and disposal areas within the construction site. 3.020 Filter Strips A vegetated section of land designed to treat runoff as overland sheet flow. They may be designed in any natural vegetated form from a grassy meadow to a small forest. Their dense vegetated cover facilitates pollutant removal and infiltration. 3.021 Final Stabilization Means that all soil disturbing activities at the site have been completed, and that a uniform perennial vegetative cover with a density of seventy-five (75) percent of the cover for unpaved areas and areas not covered by permanent structures has been established or equivalent permanent stabilization measures have been employed. 3.022 Hydric Soils Soils that are saturated, flooded, or ponded long enough during the growing season to develop anaerobic conditions in the upper part.
