A. 
The purpose of this Article is to protect and further the public interest by regulating land disturbance, filling, stripping and soil storage in connection with the clearing and grading of land for construction-related or other purposes. With these regulations, the County will promote the coexistence of the natural environment with planned development, assist in the County's efforts to comply with the Phase II Storm Water National Pollutant Discharge Elimination System (NPDES) regulations, provide effective stormwater management, protect property from damage due to flooding and erosion, improve water quality and reduce water pollution, control construction site impacts on stormwater, prevent non-stormwater discharges into the storm sewer system, protect natural stream assets using buffer strips, and protect valuable natural water resources. This includes protection of existing vegetation for use as buffer strips. The County hereby recognizes that the nature of temporary construction controls is time critical. Techniques and objectives are encouraged by the County to promote coexistence of the natural environment and planned development. It is also the purpose of this Article to encourage responsible development and minimize the impacts of development.
B. 
This Article establishes substantive and procedural requirements to:
1. 
Protect the water quality of the streams, rivers, lakes and drainage areas within Jefferson County. To be in compliance with the Phase II Stormwater National Pollutant Discharge Elimination System (NPDES) as mandated through the Clean Water Act, specific activities shall be undertaken and regulated by the County. This Article establishes substantive and procedural and enforcement requirements for:
a. 
Illicit discharge detection and elimination;
b. 
Construction site stormwater runoff control; and
c. 
Post-construction stormwater management in new development and redevelopment.
The Erosion and Sediment Control/Stormwater Management Design Manual contains the activities and BMPs required to fulfill these requirements.
2. 
Protect and enhance the water quality of watercourses, water bodies and wetlands by controlling erosion, sedimentation and related environmental damage caused by construction-related or other activities; and
3. 
Encourage creative approaches to development, including low impact development (LID), that are designed and implemented to be sensitive to the natural environment thereby resulting in high quality development for those who visit, reside and work in the County.

[Ord. No. 17-0244, 4-24-2017]
A. 
It is the policy of the County that all land disturbance activity be performed in a manner consistent with the requirements of this Chapter, except as otherwise specifically provided, in a manner that promotes the co-existence of the natural environment and quality, planned development, effective stormwater management and responsible development.
1. 
Regulations. The Director may prepare or cause to be prepared and may recommend the adoption of regulations necessary to implement this Chapter.
2. 
Construction Standards. The Director is hereby authorized to prepare for adoption by the County construction standards for erosion and sediment controls based upon sound engineering judgment. Copies of any such construction standards shall be available in the office of the Department of Public Works.
3. 
County's Right To Enter. In making an application for a permit covered by this Chapter, the applicant or the landowner performing or allowing the work shall cooperate with the County in the processing and administering of the permits, including being reasonably available for site inspections, so that the County may verify compliance with the approved plan. If work is necessary to bring the site into compliance with the approved plan prior to entering the site, the County shall contact the applicant's responsible personnel or the landowner and give them the opportunity to accompany the County personnel on any site visit. Except in an emergency, the County shall give an applicant or landowner at least twelve (12) hours' prior notice of any such inspection.
4. 
Waiver Of Requirements. The Director is hereby authorized to waive any requirement contained in this Article upon a finding that for the purposes and policy of this Article, as set forth in Sections 505.140 and 505.160 respectively, are otherwise accomplished.
[Ord. No. 17-0244, 4-24-2017]
A. 
Grading erosion control practices, sediment control practices and waterway crossings shall comply with the erosion and sediment control/stormwater design criteria and shall be adequate to prevent erosion and the transportation of sediment from the site to the maximum extent practicable. Cut and fill slopes shall be no greater than 3:1, except where recommended on an engineering soils report prepared by an engineer licensed in the State of Missouri.
B. 
Buffer Strips.
1. 
Clearing and grading of natural resources, such as buffer strips along designated natural streams, forests and wetlands, shall not be permitted, except when in compliance with this Chapter. No land disturbance shall occur on any parcel of land that is within or partially within a defined buffer strip unless the land disturbance is in compliance with the provisions of this Chapter.
2. 
Land disturbance and development shall not occur in floodways, unless allowed by a floodplain development permit as approved by the County.
3. 
Land disturbance or development shall not occur along watercourses within twenty-five (25) feet from the top of the bank on first (1st) and second (2nd) order streams and one hundred (100) feet from the top of the bank on third (3rd) and higher order streams, wetlands and sink holes, except as provided for in Subsection (D) of this Section. This strip of land is called the buffer strip and consists of the area of land extending along a side of a stream. If a watershed plan has been developed for a watershed within Jefferson County and accepted by the County Council as an element of the Master Plan, unique conditions in that watershed may dictate the need for a wider buffer strip. In those cases, the recommendation for riparian buffer strips in the watershed plan will be the controlling factor.
4. 
Buffer strips are divided into two (2) zones, the streamside zone and the outer zone. The "streamside zone" is the area within twenty-five (25) feet from the top of the bank on first (1st) and second (2nd) order streams and fifty (50) feet from the top of the bank on third (3rd) and higher order streams, wetlands and sink holes. The "outer zone" is the area outside of the streamside zone within one hundred (100) feet from the top of the bank on third (3rd) and higher order streams, wetlands and sink holes.

Except as otherwise provided, the County must provide written notice to the permittee or a representative of the permittee when a stop work order is issued. A copy of the order, in the case of work for which there is a permit, shall be mailed by first class mail, postage pre-paid, to the address listed by the permittee on the permit. In the case of work for which there is no permit, a copy of the order shall be mailed to the person listed as owner of the property by Jefferson County. That notice must specify the extent to which work is stopped and the conditions under which work may resume. The permittee is responsible for the actions of agents of the permittee and must notify those agents when a stop work order is issued that will affect an area within which the agents are to work. In this regard, "agent" is defined as any person who acts at the instruction, with the permission, or to the benefit of the permittee. A hearing shall be held before the Director within forty-eight (48) hours after the issuance of the stop work order unless resolved prior to the time of the hearing.

County's Right To Correct And Recover Costs On Active Land Disturbance Sites.
1. 
Within ten (10) days after posting the order, the County (if the deficiencies specified in the stop work order have not been satisfied) may issue a notice of intent to the permittee, owner or land user of the County's intent to perform work necessary to comply with this Chapter pursuant to the guarantee agreement. The County may go on the land and commence work after fourteen (14) days from issuing the notice of intent. The costs incurred by the County to perform this work shall be paid out of the performance guarantee required by Section 505.200.
2. 
Whenever the County finds that a default has occurred in the performance of any term or condition of the permit, approved plan, performance guarantee or a violation of Section 505.130(C) has occurred, written notice of default must be given to the permittee and to the surety or issuing organization or entity. The notice must state the work to be done, the estimated cost and the specified period of time deemed by the County to be reasonably necessary for completion of the work.
3. 
In the event of any default in the performance of any term or condition of the permit or performance guarantee, the County, the surety, the issuing organization or entity or any person employed or engaged on its behalf has a right to go upon the site to complete the required work necessary to control erosion and sedimentation or to protect properties, watercourses and persons. In the event the County undertakes this work with the funds from a forfeited performance guaranty, the funds must be used to pay the cost of contracting, including engineering and administration, for necessary restoration of the site to control erosion and sediment/stormwater within the requirements of the approved plan, permit, performance guarantee or this Chapter.
4. 
In the event any soil, earth, sand, gravel, rock, stone or other material that is caused to be deposited upon or to roll, flow or wash upon any public or private property in violation hereof and is not removed after notice as provided in Section 505.290(A), the County may cause the removal. The failure to remove shall be treated as a default on the performance guarantee and remedy the default as authorized by Section 505.280(D)(4).
5. 
Revocation Of Permit.
a. 
The Director shall revoke the permit if the permittee fails or refuses to cease work pursuant to a stop work order issued in conformity with this Chapter.
b. 
The County shall immediately revoke the permit upon failure of any permittee to maintain the performance guarantee.
F. 
County's Right to Correct and Recover Costs On Repairs to Permanent Stormwater BMPs.
1. 
The County may issue a Notice of Corrective Action Required when it performs an inspection on a Stormwater BMP and finds it to not be in compliance with the original design requirements. Inspections may be triggered from complaints of insufficient care or as part of a routine inspection to ensure compliance.
2. 
After a Notice of Corrective Actions Required, the responsible party will have thirty (30) days to correct the deficiency or enter into a contract with a third party who will be acting on their behalf. If the BMP services parts of the Urbanized Area of the County and no corrective actions are taken within thirty (30) days of the Notice of Corrective Actions Required, the County will issue a Notice of Intent to the responsible party. The County may go on the property and perform corrective actions after thirty (30) days from issuing the Notice of Intent. The cost incurred by the County to perform the work will be recuperated per the guidelines in Section 505.050.

Other Laws. Neither this Chapter nor any decision made with respect hereto exempts the applicant or any other person from other requirements of the County Code or from State and Federal laws or from procuring other required permits, nor do they limit the right of any person to maintain, at any time, any appropriate action, at law or in equity, for relief or damages against the applicant or any person arising from the activity regulated by this Chapter.
