Boundary Survey
The process of locating property lines by establishing a property corners of a parcel for building permit purposes, or locating easement lines or to resolve property disputes.
*Made by traversing.
Cadastral Survey
are made to resurvey/retrace the boundarries of municipalities & of state, federal jurisdictions & other public lands within public land surveying systems of the United States.
Geodetic Survey
When surveys are such wide extent that the curvature of the earth is a matter of importance they are called geodetic surveys.
*generally make use of a coordinate system to locate points on the earth.
Metes and bounds
The survey describes land by boundary dimensions and shapes.
Record or As-Built Survey
For locating existing structures on a parcel of land a record or as-built survey is conducted.
Existing Topography
mapping of the existing (pre-development) land surface elevations, water bodies, geology, and other features that describe a piece of property.
Flood Plain
area adjacent to a stream of body of water that is susceptible to flooding.
Floodway
the channel of a river or other watercourse and the adjacent land areas that must be reserved in order to discharge the 100-year flood without cumulatively increasing the water surface elevation.
Karst
areas where the dissolution of limestone or other soluble rocks has produced cliffs, sinkholes, caves, underground streams, and other similar features.
Ponds
a small, still body of water.
Property Use
evaluating the existing property use is important in understanding the impact from the proposed development or the project site.
Soil Type (or hydrologic soil group)
a term used to estimate the stormwater runoff potential. Defined by “A” “B” “C” or “D”
“A” Lowest Runoff / Highest Infiltration Rate
“D” Highest Runoff / Lowest infiltration Rate
Stream
a body of moving water in a natural channel, such as a creek or river.
Stream Buffer
a natural area boundary between a development and stream that helps protect water quality by filtering pollution and infiltrating stormwater runoff.
Vegetated Cover
vegetation can heavily influence the runoff potential from a site.
Wetland
wetlands occur at the transition zone between land and water / those areas that are inundated or saturated by surface or groundwater at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions.
Waters of the State
All rivers, streams, lakes and other bodies of surface and subsurface water lying within or forming a part of the boundaries of the state which are not entirely confined and located completely upon lands owned, leased, or otherwise controlled by a single person or by two or more persons jointly or as tenants in common and includes waters of the United States lying within the state.
Arid Areas
areas with an average annual rainfall of 0 to 10 inches.
Best Management Practices
schedules of activities, prohibitions of practices, maintenance procedures, and other management practices to prevent or reduce the discharge of pollutants to waters of the United States.
Includes treatment requirements, operating procedures, and practice to control plant site runoff, spillage or leaks, sludge or waste disposal, or drainage from raw material storage.
Commencement of Construction Activities
the initial disturbance of soils associated with clearing, grading, or excavating activities or other construction related activities (ex. stockpiling of fill material)
Control Measure
used in this permit, refers to any BMP or other method used to prevent or reduce the discharge of pollutants to waters of the United States.
Discharge
used without qualification means the “discharge of a pollutant”
Discharge of Storm Water Associated with Construction Activity
used in this permit, refers to a discharge of pollutants in storm water from areas where soil disturbing activities (ex. clearing, grading or excavation), construction materials or equipment storage or maintenance (ex. fill piles, borrow area, concrete truck washout, fueling), or other industrial storm water directly related to construction process (ex. concrete or asphalt batch plants) are located.
Eligible
qualified for authorization to discharge stormwater under this general permit.
Facility or Activity
means any “point source” or any other facility or activity (including land or appurtenances thereto) that is subject to regulation under the NPDES program.
Federal Facility
any buildings, installations, structures, land, public works, equipment, aircraft, vessels, and other vehicles and property, owned by, or constructed or manufactured for the purpose of leasing to, the Federal government.
Final Stabilization
All soil disturbing activities at the site have been completed.
Indian Country
All land within the limits of any Indian reservation under the jurisdiction of the United States.
All dependent Indian communities with the borders of the United States whether within the originally or subsequently acquired territory thereof, and whether within the limits of a state.
All Indian allotments, the Indian titles to which have not been extinguished, including rights-of-ways running through the same.
Large Construction Activity
includes clearing, grading, and excavating resulting in a land disturbance that will disturb equal to or greater than five acres of land or will disturb less than five acres of total land area but is part of a larger common plan of development or sale that will ultimately disturb equal to or greater than five acres.
Does not include routine maintenance that is performed to maintain the original line and grade, hydraulic capacity, or original purpose of the site.
Municipal Separate Storm Sewer System or MS4
a conveyance or system of conveyances (including roads with drainage systems, municipal streets, catch basins, curbs, gutters, ditches, man-made channels, or storm drains)
New Project
the “commencement of construction activities” occurs after the effective date of this permit.
Ongoing Project
the “commencement of construction activities” occurs before the effective date of this permit.
Operator or Owner
the owner or operator of any “ facility or activity” subject to regulation under NPDES program.
Permitting Authority
the United States Environmental Protection Agency, EPA, a regional administrator of the Environmental Protection Agency or an authorized representative.
Point Source
any discernible, confined, and discrete conveyance, including but not limited to, any pipe, ditch, channel, tunnel, conduit, well, discrete fissure, container, rolling stock concentrated animal feeding operation, landfill leachate collection system, vessel or other floating craft from which pollutants are or may be discharged.
This term does not include return flows from irrigated agriculture or agricultural storm water runoff.
Pollutant
dredged spoil, solid waste, sewage, garbage, sewage sludge, chemical wastes, biological materials, heat, wrecked or discarded equipment, rock, sand, cellar dirt and industrial or municipal waste.
Receiving Water
the water of the united states into which the regulated storm water discharges.
Runoff Coefficient
the fraction of total rainfall that will appear at the conveyance as runoff.
Semi-Arid Areas
areas with an average annual rainfall of 10 to 20 inches.
Site
the land or water area where any “facility or activity” is physically located or conducted, including adjacent land used in connection with the facility or activity.
Small Construction Activity
includes clearing, grading, and excavating resulting in a land disturbance that will disturb equal to or greater than one acre and less than five acres of land or will disturb less than one acre of land but is part of a larger common plan of development or sale that will ultimately disturb equal to or greater than one acre and less than five acres.
Storm Water
storm water runoff, snow melt runoff and surface runoff and drainage.
