Sediment As Stormwater Pollution Sediment is a leading pollutant of urban streams, and new local, state and federal regulations require the use of adequate erosion and sediment control (ESC) measures. National and local studies have shown repeatedly that dispersed or “nonpoint” sources of pollution carried by stormwater runoff are major contributors to water pollution.
The National Water Quality Inventory, 1996 Report to Congress stated
that stormwater runoff is the leading cause of water quality impairment
on a nationwide basis. Recent local studies by the U.S. Geological
Survey and Kansas City, Missouri reveal that many pollutants in our area
streams exceed national standards.
Best Management Practices (BMPs) Developers, engineers, and planners must control volumes and quality of stormwater discharges as our watersheds develop--crucial elements for protecting human life and property, maintaining water quality, and creating environmentally sensitive site designs.
Pre- and post-development stormwater best management practices (BMPs) are a major element of environmentally sound development. In the broadest sense, a stormwater BMP is any action or practice aimed at reducing flow rates and pollutant concentrations in urban runoff. In practice, BMPs typically include “nonstructural” practices such as preserving natural vegetation, particularly next to streams; and “structural” practices like vegetated swales, stormwater wetlands, and wet detention basins planted with native vegetation. BMPs are “best practices” because they provide benefits beyond stormwater management, and often cost less over time than traditional practices.
Building construction sites are required to utilize and maintain
adequate erosion and sediment control (ESC) measures per the conditions
of the building permit. To report erosion and drainage concerns on
building construction sites, you may contact the Building Permit and
Inspections Department at 816-439-4530.
Undeveloped lots in
residential subdivisions, large land disturbance areas (grading,
earthmoving, etc.), and City public works projects are required to
utilize and maintain adequate ESC measures per the conditions of the
City Land Disturbance Permit or City construction contract. To report
erosion and drainage concerns on undeveloped or Public Works
construction sites, you may contact the Engineering Division at
Creek Erosion & Drainage Concerns Most drainage concerns on private property are a private or civil matter. The City typically has no jurisdiction or responsibility for drainage or erosion issues on private property unless a public facility is contributing directly to the problem. Water is a "common enemy" and Missouri has a "modified common enemy doctrine" which requires land owners to make reasonable use of their land as it relates to water issues with neighbors.
Property owners are responsible for protecting their own property and may take measures to correct erosion issues. However, the U.S. Army Corps of Engineers has jurisdiction over all waterways of the U.S. so property owners must contact the U.S. Army Corps of Engineers, Kansas City District and City of Liberty for permit requirements prior to any creek stabilization efforts. If you have questions regarding drainage, erosion, or sedimentation issues, you may contact the Engineering Division at 816-439-4500.
