35 <br />MINNESOTA RULES 6115.0211 <br />D. is of the minimum practicable size; and <br />E. is not an obstruction to flood flows or longshore drift and is adequately designed to resist <br />the natural forces of ice, wind, and wave. <br />Subp. 4. Breakwaters. A permit is required for the construction or reconstruction of all offshore <br />breakwaters. These structures shall be approved if the following general conditions and the additional <br />listed specific conditions are met: <br />A. alternative dock or inland facilities are infeasible; <br />B. the structure is limited to those waters where: <br />(1) prevalent wind, wave, or current conditions along the shoreline are of a magnitude <br />and frequency that preclude the use and maintenance of docks to moor watercraft. Determinations <br />of magnitude and frequency that would inhibit the use of docks is based on supporting facts <br />including: <br />(a) the character of the water involved and its shoreline in relation to exposure to <br />severe wind, wave, or current actions and the configuration and area of the water; <br />(b) the frequency of occurrence of storms producing severe winds and waves based <br />on climatological data for the area; and <br />(c) the average number of days during each month of the navigational season when <br />the shoreline is affected by severe wind, waves, or currents; and <br />(2) the conditions of the site and the number, type, or size of watercraft intended to be <br />moored would preclude the development and use of on -land facilities, such as rollers, winch and <br />track systems, sliderails, or other facilities that could be used to haul watercraft out of the water <br />for on -land storage; <br />C. the facility is adequate in relation to appropriate engineering factors, including but not <br />limited to those listed in part 6115.0201, subpart 5, item E, subitem (2), units (f) to (n); <br />D. the plan is adequate in relation to the geologic and hydrologic factors listed in part <br />6115.0201, subpart 5, item E, subitem (2), units (a) to (e); <br />E. the structure is designed in a compact fashion so as to blend in with the surrounding <br />shoreline and so that all mooring and maneuvering activities can be normally confined to an area <br />bounded by the property lines as extended into the public waters while minimizing the surface area <br />occupied in relation to the number of watercraft to be served; and <br />F. the breakwaters do not exceed the minimum thickness necessary to withstand the <br />anticipated forces consistent with maintenance requirements and are faced with an adequate layer <br />of natural rock riprap of appropriate size and gradation. <br />Subp. 4a. Mooring facilities. Except as provided in part 6115.0210, subpart 4, item A, a permit <br />is required for the construction of all offshore mooring facilities. A mooring facility shall be approved <br />if the following general conditions and the additional listed specific criteria are met: <br />Copyright © 2019 by the Revisor of Statutes, State of Minnesota.
