Article 5
Sec 7.05.002

The following words and phrases, when used in this Article, shall have the meaning set out herein:

BUFFER is vegetated area or zone, including trees, shrubs, and herbaceous vegetation, that exists or is established to protect a stream system or other water resource.

BUFFER PLAN is a plan approved by the City pursuant to Section 7.05.004 of this Article.

CONSTRUCTION FENCING is four foot (4') high orange mesh, or other vibrant color approved by the City.

DEVELOPMENT means any human-made change to improved or unimproved real estate that requires an application or permit to be filed with the City, including but not limited to, buildings, fences and other structures; mining, dredging and drilling operations; grading, site clearance, paving, excavation and filling; storage of equipment and materials.

DIRECTOR is the Director of Water Pollution Control or any duly authorized representative.

MIDDLE ZONE means the variable width zone that lies between the streamside zone and the outer zone of the stream buffer.

OUTER ZONE means the zone that is adjacent to the outer boundary of the middle zone of the stream buffer.

RECREATIONAL USE is any recreational use which utilizes a pervious facility such as picnic areas, playgrounds, paths and trails. It does not include parking lots and paved facilities or other uses involving impervious surfaces, such as hard surface tennis and basketball courts.

STORM SEWER SYSTEM is the system of conveyance of storm water which includes structures such as pipes, culverts, paved channels, catch basins and storm drains.

STORM WATER MANAGEMENT PROGRAM is the program developed by the City to satisfy the requirements of 40 CFR Part 122.26(d) and 10 CSR 20-6, 200(4), as may be amended from time to time.

STREAM is a body of running water moving over the earth's surface that flows at least part of the year, such as a creek, rivulet or river. Storm sewer systems and roadside ditches are not considered streams. Streams regulated by this Article are shown on the Stream Map.

STREAM BANK is a line formed by the outer boundary of the stream as delineated by the bank-full or channel-forming flow caused by approximately the two-year rainfall event.

STREAM BUFFER is the area or zone established to protect a stream system.

STREAM CORRIDOR is a stream and the adjacent buffer that is set aside in conformance to this Article and which is substantially preserved in a natural state.

STREAM MAP is the map approved by the City pursuant to Section 7.05.003 of this Article.

STREAM ORDER is a classification system for streams based on stream hierarchy and the position within a watershed. The smaller the stream, the lower its numerical classification. Stream order is determined by a combination of factors, including the confluence of smaller streams, increased flow from contributing water sources and the size of the watershed that feeds the stream. First order streams are the smallest streams regulated by this Article; the term does not include roadside ditches. Streams orders are designated on the Stream Map adopted pursuant to this Article.

STREAM SETBACK means the specified distance from each side of a stream bank or water resource in which restrictions on development activities and land uses are imposed.

STREAMSIDE ZONE means the thirty-five foot (35') zone adjacent to the stream bank.

VIEW CORRIDOR is one or more areas, not to collectively exceed the lesser of (i) seventy five feet (75') or (ii) forty percent (40%) of the width of any platted lot or parcel which is within a stream buffer, which may be pruned by permit to a level of not less than three feet (3') above the ground to provide aesthetic views of streams for the owner of such lot or parcel.

WATER POLLUTION HAZARD means any land use or activity that causes a relatively high risk of potential water pollution.

WETLANDS are those areas that are inundated or saturated by surface water 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.
