<br />preventing, and minimizing degradation of surface water, including construction-phasing,
<br />minimizing the length of time soil areas are exposed, prohibitions, and other management
<br />practices published by state or designated area-wide planning agencies. (Refer to the current
<br />versions of the Minnesota Pollution Control Agency's publications, "Protecting Water Quality in
<br />Urban Areas," and, "Storm-Water and Wetlands: Planning and Evaluation Guidelines for
<br />Addressing Potential Impacts of Urban Storm-Water and Snow-Melt Runoff on Wetlands," the
<br />United States Environmental Protection Agency's, "Storm Water Management for Construction
<br />Activities: Developing Pollution Prevention Plans and Best Management Practices," and the
<br />Minnesota Department of Transportation's, "Erosion Control Design Manual" for suitable
<br />BMP's.)

<br />Buffer -A protective vegetated zone located adjacent to a natural resource, such as a
<br />water of the state, that is subject to direct or indirect human alteration. The width of a buffer strip
<br />is the width along each bank of a stream. Therefore a 30 foot wide stream with 100 foot buffer
<br />strips has a total width of 230 feet. Acceptable buffer vegetation includes preserving existing
<br />predevelopment vegetation and/or planting locally distributed native Minnesota trees, shrubs and
<br />grassy vegetation. Alteration of such areas is strictly limited. Buffer areas are designated with
<br />permanent signs. Refer to the City of Ramsey Tree Book and Minnesota Department of Natural
<br />Resources' Minnesota Rules chapter 6216 for a list of exotic, prohibited, regulated, unlisted and
<br />unregulated plant species. Buffer widths in Ramsey are defined in the Wetland Buffer,
<br />Shoreland Protection and River Corridor ordinances found in the City Code.
<br />
<br />Developer - A person, firm, corporation, sole proprietorship, partnership, state agency, or
<br />political subdivision thereof engaged in a land disturbance activity.
<br />
<br />Discharge - The conveyance, channeling, runoff, or drainage, of storm water, including
<br />snowmelt, from a construction site.
<br />
<br />Energy Dissipation - This refers to methods employed at pipe outlets to prevent erosion.
<br />Examples include, but are not limited to; aprons, riprap, splash pads, and gabions that are
<br />designed to prevent erosion.
<br />
<br />Erosion - Any process that wears away the surface ofthe land by the action of water,
<br />wind, ice, or gravity. Erosion can be accelerated by the activities of people and nature.
<br />
<br />Erosion Control- Refers to methods employed to prevent erosion. Examples include
<br />soil stabilization practices, horizontal slope grading, temporary or permanent cover, and
<br />construction phasing.
<br />
<br />Erosion and Sediment Practice Specifications or Practice - The management
<br />procedures, techniques, and methods to control soil erosion and sedimentation as officially
<br />adopted by either the city, county or local watershed group, whichever is more stringent.
<br />
<br />Exposed Soil Areas - All areas of the construction site where the vegetation (trees,
<br />shrubs, brush, etc.) has been removed. This includes topsoil stockpile areas, borrow areas and
