FILE # LA19-000003 <br />19 February 2019 <br />Page 3 of 4 <br /> <br />(2) Structures will have a low flood damage potential; <br />(3) Structures will be constructed an placed so as to offer a minimal obstruction to the <br />flow of flood waters; <br />(4) Service utilities, such as electrical and heating equipment, within these structures <br />must be elevated to or above the regulatory flood protection elevation or properly <br />floodproofed; <br />(5) Structures must be elevated on fill or structurally dry floodproofed in accordance with <br />the FP1 or FP2 floodproofing classifications in the state building code. All floodproofed <br />structures must be adequately anchored to prevent flotation, collapse or lateral <br />movement and designed to equalize hydrostatic flood forces on exterior walls. <br />(6) As an alternative, an accessory structure may be internally/wet floodproofed to the <br />FP3 or FP4 floodproofing classifications in the state building code, provided the <br />accessory structure constitutes a minimal investment and does not exceed 576 square <br />feet in size. Designs for meeting this requirement must either be certified by a <br />registered professional engineer or meet or exceed the following criteria: <br />a. To allow for the equalization of hydrostatic pressure, there must be a minimum of <br />two "automatic" openings in the outside walls of the structure, with a total net <br />area of not less than one square inch for every square foot of enclosed area <br />subject to flooding; and <br />b. There must be openings on at least two sides of the structure and the bottom of <br />all openings must be no higher than one foot above the lowest adjacent grade to <br />the structure. Using human intervention to open a garage door prior to flooding <br />will not satisfy this requirement for automatic openings. <br />(d) Structural works for flood control that will change the course, current or cross section of <br />protected wetlands or public waters are subject to the provisions of Minn. Stat. § <br />103G.245. <br />(e) A levee, dike or floodwall constructed in the floodway must not cause an increase to the <br />one percent chance or regional flood. The technical analysis must assume equal <br />conveyance or storage loss on both sides of a stream. <br />(f) Floodway developments must not adversely affect the hydraulic capacity of the channel <br />and adjoining floodplain of any tributary watercourse or drainage system. <br />A CUP may be granted subject to such conditions as the Council may prescribe. Additionally, <br />a CUP shall remain in effect as long as the conditions imposed by the City Council are <br />observed, but nothing in this section shall prevent the city from enacting or amending official <br />controls to change the status of conditional uses. <br /> <br />Conditional Use Permit Analysis <br />Orono’s concurrent jurisdiction over permanent docks is primarily via the City’s floodplain <br />regulations, which provide no significant standards pertinent to the approval of permanent <br />docks. Both permanent and seasonal docks fall under the zoning category of accessory <br />structures, so with the exception of the RS District, one cannot have a permanent or seasonal <br />dock without a principal residence structure. This property is zoned RR-1B. <br /> <br />There are no specific Building Code construction standards for docks. The City will require that a <br />zoning permit be issued to document the existence and construction of the permanent dock and
