City Code Chapter 11, Sec. 11.55, shall be and hereby is amended by adding Items #10 and #11 to read as follows: Subd.7. REGULATIONS AND REQUIREMENTS FOR ALL LAND ALTERATIONS A. 10. All new storm water quality facilities shall be designed based on National Urban Runoff Program (NURP Design Criteria), as follows: (a) A permanent pond surface equal to 2% of the impervious area draining to the pond or 1% of the entire area draining to the pond, whichever amount is greater; (b) An average permanent pool depth of 4 to 10 feet; (c) A permanent pool length to width ratio of 3:1 or greater; (d) A minimum protective shelf extending 10 feet into the permanent pool with a slope of 10:1, beyond which slopes should not exceed 3:1; (e) All storm water quality facilities shall have a devise to keep oil, grease, and other floatable material from moving downstream as a result of normal operations. 11. Construction site erosion and sediment control shall be mitigated by the following criteria which shall apply only to construction activities that result in runoff leaving the site. (a) Channelized runoff from adjacent areas passing through the site shall be diverted around disturbed areas, if practical. Otherwise, the channel shall be protected as described as follows. Sheet flow runoff from adjacent areas greater than 10,000 sq. ft. in area shall be diverted around disturbed areas, unless shown to have result in runoff rate of less than 0.5 cubic feet/second across the disturbed area for the one year storm. Diverted runoff shall be conveyed in a manner that will not erode the conveyance and receiving channels. (b) All activities on the site shall be conducted in a logical sequence to minimize the area of bare soil exposed at any one time. (c) Runoff from the entire disturbed area on site shall be controlled by meeting either subsections 1 and 2 or 1 and 3. 1. All disturbed ground left inactive for 14 or more days shall be stabilized by seeding or sodding (only available prior to September 15) or by mulching or covering or other equivalent control measure. 2. For sites with more than 10 acres disturbed at one time, or if a channel originates in the disturbed area, one or more temporary permanent sedimentation basins shall be constructed. Each sedimentation basin shall have a surface area of at least 1% of the area draining to the basin and at least 3 feet of depth in constructed in accordance with accepted design specifications. Sediment shall be removed to maintain a depth of 3 feet. The basin discharge rate shall also be sufficiently low as to not cause erosion along the discharge channel or the receiving water. 3. For sites with less than 10 acres disturbed at one time, silt fences, straw bales, or equivalent control measures shall be placed along the side slope and down slope sides of the site. If a channel or area of concentrated runoff passes through the site, silt fences shall be placed along the channel edges to reduce sediment reaching the channel. The use of silt fences, straw bales, or equivalent control measures must include a maintenance and inspection schedule, and assurances that they will be removed when no longer needed. (d) Any soil or dirt storage piles containing more than 25 cubic yards of material should not be located with a down slope drainage length of less than 25 feet from the toe of the pile to a roadway or drainage channel. If remaining for more than 7 days, they shall be stabilized by mulching, vegetative cover, tarps, or other means. Erosion from piles which will be in existence for less than 7 days shall be controlled by placing straw bales or silt fence barriers around the pile. In street utility repair or dirt storage piles located closer than 25 feet of a roadway or a drainage channel must be covered with tarps or suitable alternative control, if exposed for more than 7 days, and the storm drain inlets must be protected with straw bale or other appropriate filtering barriers. Section 2. City Code Chapter 1, entitled "General Provisions and Definitions Applicable to the Entire City Code Including Penalty for Violation" and Section 11.99 entitled "Violation a Misdemeanor" are hereby adopted in their entirety, by reference, as though repeated verbatim herein. Section 3. This ordinance shall become effective from and after its passage and publication.
