1 2. Development must be planned and conducted in a manner that will minimize the 2 extent of disturbed areas,runoff velocities, erosion potential, and reduce and delay 3 runoff volumes. Disturbed areas must be stabilized and protected as soon as 4 possible and facilities or methods used to retain sediment on the site. 5 3. When development density, topographic features, and soil and vegetation 6 conditions are not sufficient to adequately handle stormwater runoff using natural 7 features and vegetation, various types of constructed facilities such as diversions, 8 settling basins, skimming devices, dikes, waterways, and ponds may be used. 9 Preference must be given to designs using surface drainage, vegetation, and 10 infiltration rather than buried pipes and manmade materials and facilities. 11 b. Specific standards: 12 1. Impervious surface coverage of lots must not exceed 25 percent of the lot area. 13 2. When constructed facilities are used for stormwater management, documentation 14 must be provided by a qualified individual that they are designed and installed 15 consistent with the field office technical guide of the local soil and water 16 conservation districts. 17 3. New constructed stormwater outfalls to public waters must provide for filtering or 18 settling of suspended solids and skimming of surface debris before discharge. 19 (5) Special provisions for commercial, industrial, public/semipublic, agricultural, forestry and 20 extractive uses and mining of metallic minerals and peat. 21 a. Standards for commercial, industrial,public, and semipublic uses. 22 1. Surface water-oriented commercial uses and industrial,public, or semipublic uses 23 with similar needs to have access to and use of public waters may be located on 24 parcels or lots with frontage on public waters. Those uses with water-oriented 25 needs must meet the following standards: 26 (i) In addition to meeting impervious coverage limits, setbacks, and other 27 zoning standards in this subdivision, the uses must be designed to 28 incorporate topographic and vegetative screening of parking areas and 29 structures; 30 (ii) Uses that require short-term watercraft mooring for patrons must centralize 31 these facilities and design them to avoid obstructions of navigation and to be 32 the minimum size necessary to meet the need; and 33 (iii) Uses that depend on patrons arriving by watercraft may use signs and 34 lighting to convey needed information to the public, subject to the following 35 general standards: 36 A. No advertising signs or supporting facilities for signs may be placed 37 in or upon public waters. Signs conveying information or safety 38 messages may be placed in or on public waters by a public authority 39 or under a permit issued by the county sheriff; 40 B. Signs may be placed, when necessary,within the shore impact zone if 41 they are designed and sized to be the minimum necessary to convey 42 needed information. They must only convey the location and name of 43 the establishment and the general types of goods or services available. 44 The signs must not contain other detailed information such as product 45 brands and prices, must not be located higher than ten feet above the 46 ground, and must not exceed 32 square feet in size. If illuminated by 47 artificial lights, the lights must be shielded or directed to prevent 48 illumination out across public waters; and 49 C. Other outside lighting may be located within the shore impact zone or 50 over public waters if it is used primarily to illuminate potential safety 51 hazards and is shielded or otherwise directed to prevent direct Page 125 of 141
