WHAT IS THE FLOODPLAIN?
A floodplain is the lowland adjacent to a river, lake or creek.
Floodplains are designated by the frequency of the flood that is large enough to cover them, for example, the 10-year, 25-year or 100-year floodplain. Flood frequencies are determined by plotting a graph of the size of all known floods for an area and determining how often floods of a particular size occur.
Another way of expressing the flood frequency is the chance of occurrence in a given year, which is the percentage of the probability of flooding each year. For example, the 100-year flood has a 1% chance of occurring in any given year.
Most of the known floodplains in the U.S. have been mapped by the Flood Insurance Administration, one of the parts of the Federal Emergency Management Agency. Copies of all of these maps for Independence are kept by Public Works.
Anyone can purchase flood insurance, whether their property is in the floodplain or not, so check with your insurance agent. For floodplain information, call (816) 325-7618 or email firstname.lastname@example.org.
WHAT IS GRADING?
Grading is any excavating or filling or combination of both.
Grading may change the contour of the land and may alter drainage. A permit is required if more than 50 cubic yards of dirt will be moved. The fee for the permit is dependent on the number of cubic yards to be moved.
Permits may be required for clearing and grubbing work depending on the size and type of work being done. Please contact Shaun Carter for information regarding grading, or clearing and grubbing work. Call (816) 325-7613 or e-mail email@example.com.
WHAT IS EROSION?
Erosion is the removal of soil particles by the flow of water.
Grading and clearing work can cause erosion. Proper measures are required to prevent erosion. These may include silt fencing or hay bales. The fee for an erosion control permit is $150 per acre. For more information, call (816) 325-7613 or e-mail firstname.lastname@example.org.
Ditches are the property owner's responsibility to maintain. Public Works does have a program for re-grading ditches through a contractor at the property owner's expense. For more information, call (816) 325-7781 or e-mail email@example.com.
Property owners are responsibility for cleaning and maintaining driveway pipes. Public Works does have a program for replacing driveway pipes through a contractor at the property owner's expense. Driveway pipes are generally in the right-of-way, so replacement requires a permit. For more information, call (816) 325-7781 or e-mail firstname.lastname@example.org.
The City cleans and replaces crossroad pipes. Curbs and gutters are the property owner's responsibility to maintain. For more information, call (816) 325-7781 or e-mail
To protect your basement from flooding, the ground should slope away from your house. Downspouts should drain away from the house's foundation but should not drain onto your neighbor's property. For more information, call (816) 325-7613 or e-mail email@example.com.
Septic systems are installed in areas where no public sewers are available. New lots must be at least 3 acres for a septic system. A permit ($10) is required for all new systems and repairs to existing systems. Systems are inspected to ensure compliance with Missouri Department of Health rules. Permits may be obtained at the Public Works Department on the third floor of City Hall. For more information, call (816) 325-7613 or email firstname.lastname@example.org.
