(C) Performance standards (SR).
(1) Screening.
(a) Generally. Screening consisting of native trees and shrubs covering a minimum of 75% of the area (leaf-on conditions) is required in the shore impact zone, bluff impact zone and wetland setback in order to retain the scenic beauty and rural character as viewed from lakes. To obtain a permit in this district, a revegetation plan acceptable to the Zoning Administrator shall be required for existing properties that do not meet this standard.
(b) Screening, alternate approach. As an alternative to the screening requirements of division (C)(1)(a) above, a property owner seeking a permit may opt to discontinue turf maintenance (mowing) within the shore impact zone and allow the natural vegetation to reestablish in this area. An area to provide access to the lake can be maintained so long as it does not exceed 10% of the width of the lot or 15 feet in width, whichever is less.
(2) Dwelling, guest quarters. For lots that meet the minimum requirements in division (B) above in regards to guest quarters, a guest quarters may be constructed in accordance with the following restrictions:
(a) Shall be located along with the principal structure on the smallest lot meeting the above requirements.
(b) Shall be a minimum of 400 square feet and maximum of 600 square feet and shall not exceed 15 feet in height;
(c) Shall be located to reduce its visibility as viewed from public waters and adjacent shorelands; and
(d) Shall be screened to reduce its visibility as viewed from public waters and adjacent shorelands by vegetation, topography, increased setback, color or other uses acceptable to the city, assuming summer leaf-on conditions.
(3) Dwelling, guest quarters - alternate approach. All lots that meet the minimum requirements of division (B) above in regards to single-family dwellings, or meet the requirements of § 152.006 of this chapter, a guest quarters may be constructed in accordance with the following limitations.
(a) The total number of bedrooms on the property shall not exceed five.
(b) The impervious coverage requirements of division (B) above must be met.
(c) The building height of an accessory structure may be increased to 25 feet where necessary to accommodate a second-story dwelling unit.
(d) The guest house shall be located to reduce its visibility as viewed from public waters and adjacent shorelands.
(e) The guest house shall be screened to reduce its visibility as viewed from public waters and adjacent shorelands by vegetation, topography, increased setback, color or other uses acceptable to the city, assuming leaf-on conditions.
(4) Stairways, lifts and landings. Stairways and lifts are the only accepted method for achieving access up and down bluffs and steep slopes to shore areas. Topographic alteration to obtain access is not allowed. Stairways, lifts and landings must meet the following design requirements.
(a) Stairways and lifts must not exceed four feet in width on residential lots. Wider stairways may be used for commercial properties, public open-space recreational properties and planned unit developments.
(b) Landings for stairways and lifts on residential lots must not exceed 32 square feet in area.
(c) Canopies or roofs are not allowed on stairways, lifts or landings.
(d) Stairways, lifts and landings may be either constructed above the ground on posts or pilings or placed into the ground; provided, they are designed and built in a manner that ensures control of soil erosion.
(e) Stairways, lifts and landing must be located in the most visually inconspicuous portions of lots, as viewed from the surface of the public water assuming summer, leaf-on conditions, whenever practical.
(f) Facilities such as ramps, lifts or mobility paths for physically handicapped persons are also allowed for achieving access to shore areas; provided that, the dimensional and performance standards of divisions (C)(4)(a) to (C)(4)(e) above are complied with.
(5) Fertilizer and pesticides. Use of fertilizer and pesticides in the shoreland impact zone or setback must be done in such a way as to minimize runoff into the shore impact zone or public water by the use of earth, vegetation or both.
(6) Impervious coverage. Impervious coverage may be increased by 5% if the following is provided:
(a) A storm water retention plan be submitted showing containment of the five-year, 24-hour storm event on the parcel; and
(b) Direct runoff of storm water to adjacent water bodies, including wetlands and adjacent parcels, shall be eliminated through the use of berms, filtration strips, swales or other permanent means.
(7) Construction. During construction, no material or temporary soil deposits shall be placed within the drip line of any existing tree to be preserved. Drip lines shall be delineated by snow-fencing or silt-fencing during construction. No equipment shall operate within six feet of any preserved tree, nor shall such equipment be operated at any time in such a manner as to break, tear, bruise or otherwise injure any living or dormant tree to be preserved.
(8) Establishment of primary use. All garages permitted without principle dwelling units shall have adequate buildable area for a principle dwelling unit, a sewer treatment system and a well. Applicants for garages without principle dwelling units shall submit a sewer design by a licensed designer for the future principle structure before obtaining a permit.
(9) Outside storage. Storage of one fish house, not licensed as a recreational vehicle, is allowed if stored not less than ten feet distance from any property line and not within the OHW setback.
(10) Fences. Fences not exceeding 72 inches in height may be constructed except within the OHW setback area. Fences not exceeding 36 inches may be constructed within the OHW setback area so long as the fencing is transparent. Under no circumstances shall a fence be constructed closer than ten feet from the surface of a public road. Materials shall consist of usual fencing materials with posts and fence of metal, wood, concrete, brick or smooth wire. Barbed or electrified wire is prohibited.
