SECTION 101.0: SCOPE
101.1 Title: These regulations shall be known as the "Land Disturbance Code" of St. Louis County, Missouri, hereinafter referred to as "this Code."
101.2 Introduction: On construction or land disturbance sites, soil is highly vulnerable to erosion by wind and water. Eroded soil endangers water resources by reducing water quality and causing the siltation of aquatic habitat for fish and other desirable species. Deposits of eroded soil also necessitate maintenance of sewers and ditches and the dredging of lakes. In addition, clearing and grading during construction cause the loss of native vegetation necessary for terrestrial and aquatic habitat. Construction activities also utilize materials and generate wastes, which if not properly controlled can pollute receiving waters.
101.3 Purpose: The purpose of this Code is to safeguard persons, protect property, and prevent damage to the environment in St. Louis County. This Code will also promote the public welfare by guiding, regulating, and controlling the design, construction, use, and maintenance of any development or other activity that disturbs or breaks the topsoil or results in the movement of earth on land in St. Louis County.
101.4 Scope: This Code provides for the safety, health and welfare of the public by regulating and controlling the design, construction, use, and maintenance of any development or other activity that disturbs land surfaces or results in the movement of earth in the unincorporated part of St. Louis County, Missouri.

SECTION 201.0 GENERAL
201.1 Design: The design of erosion and settlement controls required for land disturbance activities shall comply with the following minimum requirements:
1. Land disturbance, erosion and sediment control practices, and watercourse crossings shall be adequate to prevent transportation of sediment from the site.
2. Materials brought to any site or property under a permit issued under this Code, where said material is intended to be utilized as fill material at the site for land disturbance, erosion or sediment control, shall consist of clean uncontaminated earth, soil, dirt, sand, rocks, gravel or masonry materials only.
3. Cut and fill slopes shall be no greater than 3:1 except as approved by the Department of Public Works or the Department of Highways and Traffic to meet other community or environmental objectives.
4. Clearing and grading of natural resources, such as forests and wetlands, shall not be permitted, except when in compliance with all other County Ordinances.
5. Clearing techniques that retain existing vegetation to the maximum extent practicable shall be used and the time period for disturbed areas to be without vegetative cover shall be minimized to the extent practical.
6. Clearing, except that necessary to establish sediment control devices, shall not begin until all sediment control devices have been installed and have been stabilized.
7. Phasing shall be required on all sites disturbing greater than thirty (30) acres of land. The size of each phase will be established by the Department of Planning at the time of plan review for the issuance of a major Land Disturbance permit.
201.2 Erosion Control Design: Erosion control requirements shall include the following:
1. Soil stabilization shall be completed within five days of clearing or inactivity in construction.
2. If seeding or another vegetative erosion control method is used, it shall become established within two weeks or the site shall be re-seeded or a non-vegetative option employed.
3. Techniques shall be employed to ensure stabilization on steep slopes and in drainage ways.
4. Soil stockpiles must be stabilized or covered at the end of each workday or perimeter controls must be in place to prevent silt from the stockpile from leaving the site.
5. The entire site must be stabilized, using a heavy mulch layer or another method that does not require germination to control erosion, at the close of the construction season.
6. Techniques shall be employed to prevent the blowing of dust or sediment from the site.
7. Techniques shall be employed to divert upland runoff past disturbed slopes.
201.3 Sediment Control Design: Sediment control requirements shall include:
1. Settling basins, sediment traps, or tanks and perimeter controls.
2. Settling basins shall be provided for each drainage area within 10 or more acres disturbed at one time and shall be sized to contain 0.5 inch of sediment from the drainage area and be able to contain a 2-year, 24-hour storm. If the provision of a basin of this size is impractical, other similarly effective Best Management Practices (BMP), as evaluated and specified in the Storm Water Pollution Prevention Plan (SWPPP), shall be provided.
3. Settling basins shall be designed in a manner that allows adaptation to provide long-term storm water management, as required by the County department(s) having enforcement authority and responsibilities described in Section 103.0 of this Code.
4. Settling basins shall have stabilized spillways to minimize the potential for erosion of the spillway or basin embankment.
5. Protection for adjacent properties by the use of a vegetated buffer strip in combination with perimeter controls.
201.4 Watercourse Design: Watercourse protection requirements shall include:
1. Encroachment into or crossings of active water courses/riparian areas and wetlands shall be avoided to the maximum extent practicable. All County, state and federal permits and approvals shall be obtained by a permit holder prior to beginning work authorized by a County Land Disturbance permit.
