Any development, stockpile, refuse, or matter in, along, across, or projecting into any floodplain which might impede, retard, or change the direction of a flow of water, either by itself or by catching or collecting debris carried by such water. The term floodplain encroachment shall not include any device or structure reasonably necessary for flood control or prevention.
A combination of provisions, changes, or adjustments to structures, moveable objects, or properties for the purpose of the reduction or elimination of the potential for flood damage from the base flood.
A. Those portions of the Floodplain Overlay District required for the passage or conveyance of the base flood in which waters will flow at significant depths or with significant velocities. It includes the channel of a river or creek and any adjacent floodplain areas that must be kept free of development and other encroachments so the base flood can be conveyed without substantial increase in flood height.
B. Specifically, the floodway is defined according to the following criteria:
Those areas defined by the effective Flood Insurance Rate Map with cross-hatching overlay of areas in Zone AE;
Those portions of the Floodplain Overlay District that must be kept free of development and other encroachments so the base flood is conveyed with no more than a one foot increase in the water surface elevations, and which areas have been identified as floodway by the Colorado Water Conservation Board within those reports (including technical addendum thereto) listed in Section 4-402 of this Code;
Where the floodway has not been so identified, it is those portions of the Floodplain Overlay District determined to be in the floodway by a detailed hydraulic analysis approved by the County Engineer as set forth in Section 4-407(B)(7) of this Code;
Where the floodway has not been so identified or determined, it is those portions of the Floodplain Overlay District where floodwater from the base flood is 18 inches or greater in depth.
C. However, in no instance shall the floodway extend less than 25 feet from the banks of the river or creek, unless such bank consists of an impervious natural rock wall or cliff which is higher than the flood elevation.

The first two vertical feet of any basement story that are exposed above existing grade are excluded from the above grade floor area calculation. The above grade portion of the basement floor area is calculated by multiplying the total basement floor area by the percentage of the volume of the basement story that is higher than existing grade.
1. If the finished floor surface of the main story of a residence is partially or completely above finished grade, then all floor area in the main story will be considered above grade floor area. All floor area in any stories above the main story will also be considered above grade floor area. The main story is defined as the story that includes, but is not limited to the kitchen, dining room, and living room.
B. Below Grade Floor Area Excepting the portion that is defined as above grade floor area, a portion of the basement floor area in which all or part of the floor is below existing grade. The first two vertical feet of any basement story that are exposed above existing grade are included in the below grade floor area calculation. Below grade floor area is calculated by multiplying the total floor area of the basement by the percentage of the volume of the basement that is below existing grade.

Improvement Location Certificate
An Improvement Location Certificate (“ILC”) is primarily used by mortgage and/or title companies to assist in residential property transactions. This certificate typically documents the location of improvements upon a parcel of land and graphically shows the location of easements and/or other encumbrances affecting the property as disclosed in information provided by the title company. Typically, the surveying methods used in the preparation of an “ILC” are not sufficient to precisely determine the location and dimensions of property lines, or the exact location of improvements upon or adjacent to the subject property. Therefore, an “ILC” should not be construed to be a land survey plat or an improvement survey plat. By State law the professional land surveyor who prepares an “ILC” must use a mandated certification that includes the following phrase “…that it is not to be relied upon for the establishment of fence, building or other future improvement lines…” For more information go to the County Surveyor’s page.

An open fire that can spread unconstrained through the environment. If not quickly controlled, the result can be a firestorm, often termed a “conflagration,” which destroys large amounts of property and threatens lives. Since prehistoric times, wildfires have been a natural force in shaping and changing Colorado’s landscape. Many of the native tree, brush, and grass species have evolved into fire-dependent vegetation. Some are so fire dependent that their combustibility increases with age, thus assuring renewal and continuation of the species. Lightning provides the ignition for most of these naturally occurring fires. Increasingly, human-caused fires may also become firestorms.

This human encroachment into the wildland is an area at increased risk of loss to wildfires.
