(a) Design Requirements. All new development, including additions or extensions to existing buildings, shall meet the design requirements of this section.
(1) All principal buildings shall be set back at least sixty-five feet from the ordinary high water mark.
(2) Within thirty-five feet of the ordinary high water mark, a maximum of 400 square feet of land shall be covered by impervious surfaces, including all structures and paving for each 100 linear feet of water frontage.
(3) No unsightly, offensive, or potentially polluting material, including, but not limited to, lawn clippings, leaves, garbage, trash, refuse, junk vehicles, junk, appliances, or toxic materials may be dumped or stored within thirty-five feet of the ordinary high water mark.
(4) Structures that extend more than five feet into the water are prohibited.
(5) Pumphouses that exceed three feet in height or nine feet in total square feet in size are prohibited.
(6) Accessory structures may not be located within five feet of the high water mark.
(7) Natural vegetation shall be maintained wherever possible. If the removal of vegetation is required, reestablishment of a compatible plant material shall be required.
(8) Existing mature trees shall be retained and incorporated into the site design where feasible. Trees in excess of six-inch caliper must be replaced by an equivalent amount, type, and quality of tree. Removal of mature trees of twelve-inch caliper or greater will be discouraged.
(9) Natural drainage courses shall be protected from grading activity.
(10) Where known, groundwater flow patterns shall not be interrupted.
(11) Slopes created by the grading of the site should generally not exceed a slope ratio of one foot of vertical slope to three feet of horizontal distance.
(12) Buildings shall be clustered as much as possible to retain open space and surrounding tree cover and to minimize changes in topography.
(13) Screening along roadways shall make maximum use of berming and landscaping but shall not interfere with site distances.
(b) Natural Vegetative Buffer. A thirty-five foot wide strip of land bordering the river shall be maintained in its natural state. Natural state shall mean native plants, shrubbery, tall grasses, and trees.
(1) Removal of vegetation in the natural vegetative buffer shall be limited to no more than twenty-five percent of the length of this buffer, provided that cutting of this twenty-five percent shall not create a clear-cut opening greater than twenty-five feet wide for every 100 feet of shoreline.
(2) Natural shrubbery, trees, or other vegetation shall be preserved as far as practical and, where removed, shall be replaced with other naturally occurring vegetation that is equally effective in retarding runoff, preventing erosion, and preserving natural beauty. A mowed lawn is not a desirable vegetative buffer adjacent to the shoreline.
(3) Native plants, shrubbery, and trees are encouraged when new vegetation is planted.
(4) Existing soil and organic matter shall not be altered or disturbed within the natural vegetative buffer.
(5) These provisions shall not apply to the removal of dead, diseased, or dying trees, at the discretion of the landowner.
(c) Drainage of Surface Water. Proper site surface drainage shall be provided so that the removal of surface waters will not adversely affect neighboring properties or the public storm drainage system. If practical, stormwater shall be removed from all roof areas, canopies, and paved areas and carried away in an underground drainage system. The peak rate of stormwater runoff from the site shall not increase as a result of the proposed development, and temporary onsite storage to reduce peak runoff from the site is encouraged. Surface water in all paved areas shall be collected at intervals so that it will not obstruct the flow of vehicular or pedestrian traffic and so that it will not create ponding.
