DRAFT 1/5/95 the grading and filling provisions of 1102.09, Subd 2 of this ordinance must be met. Subd. 4. Stormwater Management. A. Impervious surface coverage of lots must not exceed the impervious surface percentage of lot area outlined in Section 1102.07 C4 of this ordinance. B. When possible, existing natural drainageways, wetlands and vegetated soil surfaces must be used to convey, store, filter, and retain stormwater runoff before discharge to public waters. C. Development must be planned and conducted in a manner that will minimize the extent of disturbed areas, runoff velocities, erosion potential, and reduce and delay runoff volumes. Disturbed areas must be stabilized and protected as soon as possible and facilities or methods used to retain sediment on the site. D. When development density, topographic features, and soil and vegetation conditions are not sufficient to adequately handle stormwater runoff using natural features and vegetation, various types of constructed facilities such as diversions, settling basins, skimming devices, dikes, waterways, and ponds may be used. Preference must be given to designs using surface drainage, vegetation, and infiltration rather than buried pipes and man-made materials and facilities. Residential, commercial and industrial subdivisions and site plans shall provide for the collection and treatment of storm water in compliance with the City Storm Water Management Plan if determined that the site improvements will result in increased runoff directly entering a public water. All grading and drainage plans shall require review and approval by the City Engineer and the Rice Creek Watershed District. E. When constructed facilities are used for stormwater management, documentation must be provided by a qualified individual that they are designed and installed consistent with the Lino Lakes Local Water Management Plan. F. Newly constructed stormwater outfalls to public waters must provide for filtering or settling of suspended solids and skimming of surface debris before discharge. 1102.10 Special Provisions for Commercial, Industrial, Public/Semipublic, Agricultural, Forestry and Extractive Uses and Mining of Metallic Minerals and Peat. Subdivision 1. Standards for Commercial, Industrial, Public and Semipublic Uses. Surface water -oriented commercial uses and industrial, public, or semipublic uses with similar needs to have access to and use of public waters may be located on parcels or lots with frontage on public waters. Those uses with water -oriented needs must meet the following standards: Page 24
