[CC 1988 § 47.050; Ord. No. 578 § 1, 10-17-1988; Ord. No. 1323 § 1, 7-20-1998; Ord. No. 1748 § 1, 8-5-2002; Ord. No. 2882 § 5, 8-2-2010; Ord. No. 2969 § 4, 4-18-2011; Ord. No. 3634 § 1, 1-17-2017]
A. 
Slope changes shall be designed to keep slope lengths and gradients to a minimum. Finished grades in excess of twenty percent (20%) slopes (five to one (5:1)) shall be hydro-seeded and mulched at one hundred (100) pounds per one thousand (1,000) square feet. Finished grades shall not exceed a three to one (3:1) slope (thirty-three percent (33%)) unless the excavation is through rock or the excavation or fill is adequately protected (a designed head wall or toe wall may be required). Retaining walls greater than four (4) feet in height shall be considered permanent structures and shall be constructed in accordance with the requirements of the International Building Code or the International Residential Code as adopted by the City of Lake Saint Louis as part of the Comprehensive Construction Code.
B. 
Sediment and erosion control plans shall provide for sediment or debris basins, silt traps or filters, staked straw bales or other approved measures to remove sediment from runoff waters. Developments of two (2) acres or more shall be required to construct sediment basins. Siltation control measures shall be initiated prior to any land disturbance and shall be maintained until vegetative cover is established at a sufficient density to provide erosion control on the site.
C. 
Temporary access shall be provided for all construction sites prior to any land disturbance to minimize curb damage and mud deposits on the streets. Said temporary access paths shall be rocked to a minimum depth of four (4) inches. An underlayment of stabilization fabric is required to keep the rock from becoming saturated with mud. Note, for residential lots temporary driveways are to be rocked immediately after foundation walls are backfilled and before the subfloor installation. All deliveries of material to the construction site shall be required to use the temporary driveway.
D. 
Where natural vegetation is removed during grading, revegetation of the site shall be initiated as soon as is practicable following the initiation of grading work. Vegetation in sufficient density to provide effective erosion control must be re-established within thirty (30) days following completion of major grading work. Unless otherwise approved in the phasing and sequencing provisions of the site's approved Erosion and Sedimentation Control Plan, temporary seeding (applied at a sufficient density, along with mulch and fertilizer as detailed in the "Engineering and Plan Preparation Manual" found in Appendix A to Title IV) must occur within fifteen (15) days following the commencement of major grading activities. Permanent type grasses shall be established as soon as possible after grading has been completed. Cultivation of seed and continued maintenance of site in such a manner as to assure germination and healthy vegetative cover is the responsibility of the developer.
E. 
When grading operations are completed or suspended for thirty (30) days, permanent grass must be established at sufficient density to provide effective erosion control. Between permanent grass seeding periods, temporary cover shall be provided.
F. 
Increased runoff caused by changed soil and surface conditions during and after grading must be accommodated. Whenever there is an increase in the amount or velocity of surface runoff, channels will be stabilized adequately to prevent erosion. Where water runoff is fast enough to cause significant erosion, debris or sediment basins, diversions or other appropriate structures shall be constructed.
G. 
Sites shall be laid out to provide positive drainage. Individual site drainage shall be coordinated with the area's general storm drainage pattern. Drainage shall be away from buildings and designed to prevent stormwater runoff from flowing onto adjacent properties.
1. 
No water runoff shall drain directly or indirectly into a sanitary sewer.
2. 
Ground adjoining development sites shall be protected from accelerated and increased surface water, silt and other effects of erosion.
3. 
Water runoff from parking lots, paved sites, buildings, etc., above the area to be developed shall be directed to debris or sediment basins, diversions, concrete gutters and/or underground outlet systems.
H. 
Buildings, decks, patios, parking lots and other improvements shall be set back a minimum of twenty-five (25) feet from the top of existing stream banks. Variances will include designed streambank erosion control measures and shall be approved by the City Engineer or Building Inspector. FEMA and U.S. Army Corps of Engineers guidelines shall apply for site development in areas designated as flood plains and/or wetlands. Every effort shall be made to protect permanent vegetation from harm during the construction process.
I. 
Occupancy permits will not be issued until final grading has been completed and lots have been seeded and mulched or sodded. When conditions prevent ground cover from being established, an occupancy permit may be issued by submitting an escrow deposit sufficient to guarantee completion.
J. 
Erosion and Sediment Control Plans are understood to be inexact. City staff shall have the authority to require additional countermeasures consistent with policies and standards adopted by the City when the countermeasures or best management practices installed or employed by the contractor on a site are deemed inadequate or ineffective. Those additional measures must be maintained as if a part of the original Erosion and Sediment Control Plan.
[CC 1988 § 47.060; Ord. No. 578 § 1, 10-17-1988; Ord. No. 1323 § 1, 7-20-1998; Ord. No. 3634 § 1, 1-17-2017]
A. 
No land disturbing, construction or other associated activities are permitted that cause mud, soil, earth, sand, gravel, rock, stone, concrete, building materials or other materials to be deposited on public streets. Trucks and other construction equipment should be cleaned on site to prevent mud from being deposited on public streets.
B. 
If mud, material or debris is deposited on a public or private street, the general contractor, subdivision representative, firm or corporation responsible for the development site concerned shall have the responsibility to take reasonable steps to modify the practices on the site to eliminate further deposits on the street and must remove the same from the street throughout the day as practical to provide for safe operation and use of the street by the public. For collector and arterial streets, the City Inspector may require mechanical sweeping of the street up to three (3) times per day in addition to other measures deemed necessary for safe operation of the street. For local streets the responsible party must clean the street of all debris at the end of each working day.
C. 
Mud deposited on the street as a result of stormwater BMP failures shall be removed within twenty-four (24) hours of a notice issued in accordance with Section 540.070.
D. 
Notification will be made by personal contact, telephone, electronic mail, or the site will be posted. The notification will include the time notified and deadline for abating the violation.
E. 
Nothing contained in this Section shall relieve a contractor, permittee, individual, firm or corporation from liability for damages resulting from their actions and practices.
[CC 1988 § 47.070; Ord. No. 578 § 1, 10-17-1988; Ord. No. 1323 § 1, 7-20-1998; Ord. No. 2882 § 6, 8-2-2010; Ord. No. 3634 § 1, 1-17-2017]
A. 
Inspections. By applying for permits in Title IV or Title V, the applicant consents to the City inspecting the grading or excavation of a site that is subject to an Erosion and Sediment Control Plan and all work in progress (the "work"). Inspection records as required by the Missouri Department of Natural Resources Land Disturbance Permit may be requested and available for review during normal business hours by City staff. Sites not subject to an Erosion and Sediment Control Plan may be inspected by City staff in the same manner outlined in Section 220.140.
B. 
Standard. The current edition of St. Charles County Standard Specifications for Subdivision Street Construction, Section 806 Erosion and Sediment Control, shall be the standard for inspections under this Chapter.
C. 
Corrections.
1. 
The City may inspect the work (the "initial inspection") and, if the inspector determines that there is a potential failure to comply with the requirements of this Chapter, notify the permittee or the permittee's representative (the "permittee") in writing of the items that need to be corrected (the "notice to correct"). The notice to correct shall at a minimum state the nature of the non-compliance, any practice or approved plan deficiency, required corrective action, and compliance time. The time limit for making the corrections shall be a minimum of seven (7) calendar days unless, in the opinion of the Director of Public Works, an imminent hazard and/or emergency exists, in which injury to persons or significant property damage is imminent (an "emergency"), at which time the City shall immediately notify the permittee of such hazard and/or emergency and shall require corrective work to begin immediately.
2. 
The permittee, if not present on the site during the initial inspection, shall have a reasonable opportunity to accompany the City's inspector on a subsequent site visit (the "site visit") to discuss the items in the notice to correct. A permittee desiring to accompany the inspector on a site visit shall make himself/herself available for the site visit no later than five (5) days after the date of issuance of the notice to correct; failure to do so will waive the site visit. After any site visit, the inspector may amend the notice to correct to reflect any agreements by the inspector and the permittee at the site visit pertaining to corrective action or compliance time and shall send such amended notice to correct to the permittee.
3. 
Upon the sooner of:
a. 
The permittee's notice that completion of the corrections set forth in the notice of correction and notification of the inspector of same, or
b. 
The expiration of the time for compliance set forth in the notice to correct, the Director of Public Works or his/her designee shall cause the work to be reinspected to determine the status of compliance (the "compliance inspection"). If the compliance inspection shows that the items on the notice to correct have been corrected, the inspector shall notify the permittee of same. Written notification that the matter is corrected and the matter is closed may be provided to the permittee upon his/her request. If the compliance inspection reveals a failure to correct some or all of the items on the notice to correct, the Director of Public Works shall notify the permittee of the deficient items that were not corrected in violation of this Chapter. The City may then proceed with all remedies for such violations set forth in Subsections (E) and (F) below.
D. 
Violations. All persons failing to comply with such notice to correct within the time period stated therein shall be deemed in violation of this Section. Notwithstanding the foregoing and except in the case of an emergency, failure of the City to allow the permittee an opportunity to accompany the inspector on a site visit as set forth in Subsection (B) above shall prohibit any further enforcement action or penalty being imposed by the City on the permittee with respect to any notice to correct arising from such initial inspection. Nothing herein shall be construed to limit the City's ability to immediately respond to complaints or concerns regarding erosion and/or stormwater control for compliance with its MS4 Permit.
E. 
Responsible Parties. The owner of a property may be cited in addition to the permittee for any offense listed in this Chapter.
F. 
Penalties. Anyone violating any of the provisions of this Chapter shall be subject to the general penalty provisions of Section 100.210. In addition to the penalties hereinabove authorized and established, the City Attorney is authorized to take such other actions at law or in equity as may be required to halt, terminate, remove, or otherwise eliminate any violation of this Chapter. The Director of Public Works may seize any performance guarantee established to ensure compliance with this Chapter including bringing the site into compliance with the approved sediment and erosion control plan.
G. 
Stop Work Orders. The Director of Public Works or Community Development shall have the power to order all work to be stopped on any building(s), structure(s), grading, storm sewer, or other construction activity, where such work is being done in violation of any provisions of this Chapter, or where work is being done, in the development as a whole, that is in violation of this Chapter. Such order shall stop work on all projects the subject contractor or subcontractor is currently engaged in at the discretion of the Community Development Administrator when he/she reasonably believes that the violation that is the subject of the stop work order materially affects the health, safety and welfare of the community and is unlikely to be corrected without such action. For purposes of this provision, the discretion of the Community Development Administrator to extend any stop work order to other work in the development as a whole, or in any other development, shall extend to work being performed under the "control" of the primary entity to which the stop work order applies or is under the control of any entity which is a "control entity" of the primary entity to which the stop work order applies as those terms are defined in Section 135.260 of the Municipal Code. Such stop work orders may be given orally and may be enforced when so given provided, however, that any oral stop work order shall be followed by a written order within two (2) hours. All work that is stopped shall not be resumed except upon permission of the Community Development Administrator. Written stop work orders may be served by any Police Officer, any Public Works Department employee or any Community Development Department employee and may be served by personal service or by posting on the premises affected.
