• • • Shoreland Management Overlay (3) Placement and design of roads, driveways, and parking areas. (a) 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 Lino Lakes local water management plan. (b) Roads, driveways, and parking areas must meet structure setbacks and must not be placed within 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. (c) 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 division are met. For private facilities, the grading and filling provisions of division (2) of this chapter must be met. (4) Stormwater management. (a) Impervious surface coverage of lots must not exceed the impervious surface percentage of lot area outlined in § 1102.07 of this chapter. (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.
