(A) Criteria. A stormwater flow control plan shall be prepared for any earth change subject to permit requirements. The plan shall be designed to effectively reduce accelerated soil erosion and sedimentation during construction and after construction is completed.
(B) Contents. The plan submitted pursuant to this section shall include the following:
(1) A map or maps at a scale of not more than 100 feet to the inch or as otherwise determined by the enforcement agency, including a legal description and site location drawing which includes the proximity of any proposed earth change to lakes or streams, or both; predominant land features; and contour intervals or sufficient spot elevations to determine existing and proposed ground slope.
(2) A soils survey or written description of the soil types of the exposed land area subject to the proposed earth change.
(3) A description and the location of the physical limits of each proposed earth change.
(4) Location of all lakes, streams and protected wetlands partially or completely contained within the boundaries of the site or within 500 feet of the site boundary.
(5) A description and the location of all existing and proposed on-site stormwater management facilities and measures.
(6) The timing and sequence of each proposed earth change.
(7) Stormwater flow calculations utilizing the rational method or the U.S.D.A. Natural Resources Conservation Service method approved by the enforcement agency.
(8) A program for the continued maintenance of all permanent stormwater flow control facilities and measures as listed in § 156.09, if applicable.
(9) In the event there are severe development limitations in regards to the existing site characteristics, the enforcement agency may require that a residential or high erosion risk plan be prepared by a licensed professional civil engineer.
(10) Other information which the enforcement agency requires to review the impact of the proposed earth change in relationship to the standards and requirements of this chapter.
