(e) Any land within the boundaries or jurisdiction of the village on which there is located a permanent stormwater control measure which was installed pursuant to this section.
2. The erosion control administrator reserves the right to require any land disturbing activity, regardless of disturbed area or type of activity, to comply with this section if it is determined to be the cause of, or a contributor to, substantial existing or potential erosion, sediment, or stormwater impact.
(C) Permanent Soil Erosion, Sediment And Stormwater Control Measures:
1. Erosion And Sediment Control Measures: All control measures required under this section shall conform to the design criteria, standards, and specifications provided in the applicable standards, referenced in appendix B attached to the ordinance codified herein, now in effect or as hereafter amended. All control measures installed shall be sufficient to prevent observable sediment from leaving the site during a 5-year frequency storm event. All sediment that moves off site due to construction activity will be cleaned up before the end of the same workday. All sediment that moves off site due to storm events will be cleaned up before the end of the next workday. For example, installing a rock construction drive or cleaning tires could be used to minimize tracking of sediment onto public roads.
2. Permanent Stormwater Control Measures: Stormwater detention facilities shall be designed for a minimum 25-year rainfall event and ten (10) minute duration. Each stormwater detention area shall be provided with a method of emergency overflow in the event that a rainfall event in excess of a 25-year rainfall event occurs. This emergency overflow facility shall be designed to function without attention or maintenance. Detention facilities shall be designed to have a dry bottom except when inundated immediately following a storm event. The stormwater runoff rate from the site shall not exceed the 2- year predevelopment stormwater runoff rate from the site. Evaluation of submitted plans shall be based on the stormwater design analysis and example in appendix A attached to the ordinance codified herein.
3. Regional Stormwater Control Systems: To allow for the beneficial development and maintenance of regional stormwater management systems, where they are available and they are appropriate, an applicant may submit a design dependent on such a system. The applicant may submit documentation of the approval for the use of the regional stormwater management facility from the governmental agency having jurisdiction over it. The applicant shall submit evidence showing that there will be no adverse flooding impact to any receiving stream between the point of discharge and the regional stormwater facility. If the erosion control administrator approves the use of a regional stormwater management system, the applicant shall be exempt from the requirements in this section for permanent on site stormwater controls. Such exemption shall not apply to any temporary stormwater control measures required by this section.
(D) Temporary Soil Erosion, Sediment And Stormwater Control Measures:
1. Temporary Control Measures Required: On site sediment control measures shall be constructed and functional prior to initiating land disturbing activities on the site. Fully functioning temporary sediment control measures (including, but not limited to, perimeter sediment controls) shall remain in place until the ground is stabilized with permanent ground cover. In cases where it is not practical to leave the temporary sediment control measures in place prior to establishing permanent ground cover (for example, when control measures need to be removed in order to grade the area or install pavement or sod), an exception will be made only if one of the conditions listed below will be met. In no way does adhering to one of the conditions below relieve the owner of responsibility to clean up or repair any damages caused from sediment or stormwater runoff leaving the site.
2. Permanent Ground Cover: Permanent ground cover shall be established with pavement, aggregate or sod within three (3) working days of the removal of temporary sediment barriers; or
3. Permanent Vegetation: Permanent vegetation shall be established by seeding with anchored mulch or erosion control blanket within three (3) working days of final grading in the spring or fall seeding periods. All disturbed areas must have permanent ground cover established within six (6) months of the project completion, or within six (6) months of occupancy, whichever comes first. Summer seeding is acceptable on project areas which shall be watered. This does not apply to concentrated flow areas.
4. Maintenance: Sediment control measures and temporary stormwater control measures are to be maintained so they are operating effectively until permanent ground surface protection and permanent stormwater control measures are established in a manner specified in the applicable permit issued pursuant to this section.
5. Additional Control Measures: The erosion control administrator may require additional control measures pursuant to the standards if determined as necessary after site inspection, and prior to issuing the permit.
(E) Retrofitting Presently Developed Sites: In instances where the project involves a presently developed site, the applicant may request an exemption from fully complying with the stormwater control requirements. The erosion control administrator shall determine the type and extent of compliance required based on existing and proposed site conditions, and the impact of stormwater runoff on the surrounding area. This exemption will only be granted in cases where the proposed condition of the site will not be significantly different from the existing condition as determined by the erosion control administrator. The purpose of this subsection is to allow for alterations to presently developed sites without a major redesign of the existing (or nonexisting) stormwater system, while assuring that all projects will be moving closer to compliance with the stormwater control requirements of this section.
(F) Residential; Erosion And Sediment Control Permit: Before commencing any project involving construction of a new single- or two-family dwelling, addition, garage or foundation, or commencing on any project disturbing an area greater than five thousand (5,000) square feet, the owner of the land, or his representative, shall file an application for a residential (1- and 2-family dwelling) erosion and sediment control permit, accompanied by a residential erosion and sediment control site plan. See appendix B attached to the ordinance codified herein for erosion, sediment and stormwater control standards.
If more than one acre of ground is being disturbed, the project must comply with the Illinois environmental protection agency (IEPA) by submitting to the IEPA a storm water pollution prevention plan (SWPPP) and notice of intent. A copy of the approved permit by the EPA must be submitted to the village of Creve Coeur before the village will issue a permit.
