2. What is erosion control and when is it required?

Erosion occurs when water or wind action moves soil. Erosion control methods attempt to limit this process. In order to minimize erosion, developers must use best management practices to limit soil movement. Examples of this include silt fences and erosion control blankets around a project site. All projects submitted for final engineering review are also examined by the Kane-Dupage Soil Conservation District (KDSCD) to insure sufficient erosion control methods are being used.

KDSCD and the Engineering Department inspect sites to assure these practices are well managed during construction. All of these efforts are required to protect waterways in Kane County from excessive silt.

1. What is an easement?

An easement is a legal provision tied to a property that modifies the rights of the owner. Conventionally, most properties have a utility easement. These easements allow the city or a utility company to access the property for a specific purpose, such as repairing a power line.

Easements are marked on your property's plat of survey. Plats of survey are given to the property owner, Lending Institution and Title Company.

3. My mortgage lender says I need flood insurance, how is this need determined?

Mortgage lenders often hire outside technical consultants to complete the floodplain determination portion of a mortgage or refinancing loan.

4. What is the 100-year floodplain?

The 100-year floodplain, or base floodplain is that area adjacent to rivers, streams and lakes that has been determined to have a 1% statistical chance of being flooded in any given year. The Federal Emergency Management Agency (FEMA) completes hydrologic and hydraulic studies of watercourses and water bodies to determine flood elevations relative to local topography. FEMA uses the term Flood Insurance Study (FIS) for these investigations. An individual FIS is completed for each municipality or county. The floodplain maps, called Flood Insurance Rate Maps (FIRMs) are the companion documents to the FIS.
