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