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 /> 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 /> 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 <br />
