Board of Adjustment
A board established by county ordinance with the authority to order the issuance of variances, hear and decide appeals from a member of the affected public and review any order, requirement, decision, or determination made by any administrative official charged with enforcing any ordinance adopted pursuant to the provision of MN Statutes, order the issuance of permits for buildings in areas designated for future public use on an official map and perform such other duties as required by the official controls.
Building Line
A line parallel to a lot line or the ordinary high water level at the required setback beyond which a structure may not extend.

Rare and distinctive wetlands, characterized by a substrate of non-acidic peat and dependent on a constant supply of cold, oxygen-poor ground water rich in calcium and magnesium bicarbonates.
Class V Injection Well
A shallow well used to place a variety of fluids directly below the land surface, which includes a domestic SSTS serving more than 20 people. Must meet certain requirements and do not endanger underground sources of drinking water.
Conditional Use
A land use or development as defined by the ordinance that would not be appropriate generally, but may be allowed with appropriate restrictions as provided by official controls.
Design Flow (SSTS)
The daily volume of wastewater for which an SSTS is designed to treat and discharge.
Drainageway
Any natural or artificial water course, including but not limited to, streams, rivers, creeks, ditches, channels, canals, conduits, culverts, waterways, gullies, ravines, or washes, in which waters flow in a definite direction or course, either continually or intermittently; and including any area adjacent thereto which is subject to inundation by reason of overflow or floodwater.
Dredging
The process by which soil materials are mechanically transported by water from a body of water in order to increase the body of water depth.
Dredge Spoils
The sediment material dredged from the bottom of a body of water.
Ecosystem Services
The conditions and processes through which natural systems sustain and fulfill human life. This includes water regulation and supply, soil formation, nutrient cycling, flood and storm protection, raw materials such as timber, air quality and carbon sequestration, and biological and genetic resources.
Equal Degree of Encroachment
A method of determining the location of floodway boundaries so that floodplain lands on both sides of a stream are capable of conveying a proportionate share of flood flows.
Flood Frequency
The frequency for which it is expected that a specific flood stage or discharge may be equaled or exceeded.
Flood Fringe
The portion of the floodplain outside of the floodway.
Floodplain
The beds proper and the areas adjoining a wetland, lake or watercourse which have been or hereafter may be covered by the regional flood.
Floodway
The bed of a wetland or lake and the channel of a watercourse and those portions of the adjoining floodplain which are reasonably required to carry or store the regional flood discharge.
General Development Lake
These lakes are generally large, deep lakes or lakes of varying sized and depths with high levels and mixes of existing development at the time of the original classification. Often extensively used for recreation.
Impervious Surface
A constructed hard surface that either prevents or retards the entry of water into the soil and causes water to run off the surface in greater quantities and at an increased rate of flow than prior to development. Examples include rooftops, sidewalks, driveways, parking lots.
Karst
The type of geologic terrain underlain by carbonate rocks where significant solution of the rock has occurred due to flowing ground water.
Management Plan (SSTS)
A plan that describes necessary and recommended routine operational and maintenance requirements, periodic examination, adjustment, and testing, and the frequency of each to ensure system performance meets the treatment expectations.
Micro WECS
A WECS of 5 kW nameplate generating capacity or less and total height of 45 feet or less.
Non-Commercial WECS
A WECS between 5 and 99 kW in total name plate generating capacity and a total height between 46 and 199 feet.
Official Controls
Legislatively defined and enacted policies, standards, precise detailed maps and other criteria, all of which control the physical development of the County and are the means of translating into ordinances all or any part of the general objectives of the comprehensive plan.
Ordinary High Water Mark (OHWM)
The boundary of public waters and wetlands, and shall be an elevation delineation the highest water level which has been maintained for a sufficient period of time to leave evidence upon the landscape, commonly that point where the natural vegetation changes from predominantly aquatic to predominantly terrestrial.
For watercourses, OHW level is the elevation of the top of the bank of the channel. For reservoirs and flowages, OHW level is operating elevation of the normal summer pool.
Pervious Surface
A surface which allows the penetration of water into the ground.
Practical Difficulty
Used in connection with granting a variance, means that the property owner proposes to use the property in a reasonable manner not permitted by an official control. The plight is due to circumstances unique to the property.
Process Wastewaters
Waters and/or precipitation, including rain or snow, which comes into contact with manure, litter, bedding, or other raw material or intermediate or final material or product used in or resulting from the production of animals.
Reach
A hydraulic engineering term used to describe longitudinal segments of a stream or river influenced by a natural or man-made obstruction, such as the segment of a river between two bridge crossings.
Regulatory Flood Protection Elevation
An elevation no lower than 1 foot above the elevation of the regional flood, plus any increases in flood elevation caused by encroachments on the floodplain that result from designation of a floodway.
Riparian
Adjacent to or living on the shore of a water body.
Sediment Control
Methods employed to prevent sediment from leaving the site; including silt fences, sediment traps, earth dikes, drainage swales, check dams, subsurface drains, pipe slope drains, storm drain inlet protection.
Sensitive Land
Land area that may include bodies of water, sites of biodiversity, bluffs, or geological sensitive areas.
Shore Impact Zone
Land located between the ordinary high water level of a public water and a line parallel to it at a setback of fifty (50) percent of the structure setback.
SSTS
Subsurface Sewage Treatment System. Includes ISTS or MSTS.
Variance
Any modification or variation of official controls where it is determined that, by reason of exceptional circumstances, the strict enforcement of the official controls would cause unnecessary practical difficulties.
Environmental Assessment Worksheets (EAW)
Rapidly assess whether or not a proposed action has the potential for significant environmental effects.
Environmental Impact Statements (EIS)
Provide information for governmental units, the proposer of the project and other persons to evaluate proposed projects which have the potential for significant environmental effects, to consider alternatives to the proposed projects and to explore methods for reducing adverse environmental effects.
