Shoreland Alterations Chapter 910: Shoreland Overlay District Page 910-7 C. Placement and Design of Roads, Driveways and Parking Areas: 1. Public and private roads and parking areas must be designed to take advantage of natural vegetation and topography to achieve maximum screening from view from public waters. Documentation must be provided by a qualified individual that all roads and parking areas are designed and constructed to minimize and control erosion to public waters consistent with the field office technical guides of the local soil and water conservation district, or other applicable technical materials. 2. Roads, driveways, and parking areas must meet shoreland setbacks and must not be placed within bluff and shore impact zones, when other reasonable and feasible placement alternatives exist. If no alternatives exist, they may be placed within these areas, and must be designed to minimize adverse impacts. 3. Public and private watercraft access ramps, approach roads, and access-related parking areas may be placed within shore impact zones provided the vegetative screening and erosion control conditions of this sub-part are met. For private facilities, the grading and filling provisions of Section 910.040.B.4 of this Ordinance must be met. D. Storm Water Management. (The following regulations shall be applied to all land alterations in the Shoreland District, in addition to the requirements of the Little Canada Stormwater Ordinance, Section 927): 1. When possible, existing natural drainage ways, wetlands, and vegetated soil surfaces must be used to convey, store, filter, and retain storm water runoff before discharge to public waters. 2. 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 in accordance with Best Management Practices. Facilities or methods shall be used to retain sediment on the site. 3. When development density, topographic features, and soil and vegetation conditions are not sufficient to adequately handle storm water 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. 4. When constructed facilities are used for storm water management, documentation must be provided by a qualified individual that they are designed and installed consistent with the field office technical guide of the local soil and water conservation districts. 5. New construction storm water outfalls to public waters must provide for filtering or settling of suspended solids and skimming of surface debris before discharge. 910.050. SPECIAL PROVISIONS FOR COMMERCIAL, INDUSTRIAL AND PUBLIC / SEMI-PUBLIC: Uses without water-oriented needs must be located on lots or parcels without public waters frontage, or if located on lots or parcels with public waters frontage, must either be set back double the normal ordinary high water level setback or be substantially screened from view from the water by vegetation or topography, assuming summer, leaf on conditions. Water-oriented need shall be determined by the Zoning Administrator.
