F.., <br /> The land area occupied by any use or development permitted by this chapter that will displace floodwaters shall <br /> not exceed two percent of the land area of that portion of the lot located in the density fringe area.The limitations <br /> of this section shall not apply to those uses listed in EMC 19.30.340. <br /> 19.30.330 Density fringe area: maximum allowable obstruction. <br /> The maximum width(sum of widths)of all new construction,substantial improvements or other development shall <br /> not exceed 15 percent of the length of a line drawn perpendicular to the known floodwater flow direction at the <br /> point where the development(s)is located.The length of said line shall not extend beyond the property boundary <br /> or the edge of the density fringe area,whichever is less.The limitations of this section shall not apply to those uses <br /> listed in EMC 19.30.340. <br /> 19.30.340 Density fringe area:exceptions to maximum allowable density and obstruction limitations. <br /> The following uses shall be exempt from the maximum allowable density and obstruction limitations of EMC <br /> 19.30.320 and 19.30.330: <br /> A. Water-dependent utilities; <br /> B. Dikes; <br /> C. Utility facilities;and <br /> D. Public works,when the project proponent demonstrates that the floodwater displacement effects of the <br /> proposal when considered together with the maximum potential floodwater displacement allowed by EMC <br /> 19.30.320 and 19.30.330 shall not cause a cumulative increase in the base flood elevation of more than one <br /> foot. Floodwater displacement information shall be obtained and certified by a professional engineer. <br /> 19.30.350 Density fringe area: recording required when density and obstruction allowances are <br /> increased. <br /> When the density and/or the allowable obstruction area in a density fringe designation is increased pursuant to <br /> EMC 19.30.320 and 19.30.330,the property owner shall record with the Auditor's office a notice in a form <br /> approved by Planning and Development Services describing the related flood hazard permit number,subject <br /> property assessor number(s)and structures included in the density fringe area calculations. <br /> 19.30.360 Density fringe area:general provisions. <br /> The following regulations shall apply to all development in the density fringe area: <br /> A. Identified natural drainage channels that are secondary to the river channel(s)in discharging floodwaters <br /> downstream during flood periods shall be preserved or maintained as open space. <br /> B. All structures and development shall be oriented parallel to known floodwater flow directions in order to <br /> minimize flow obstruction. Determination of such orientation shall be based upon topographical and historical <br /> flood data.When such information is not available,orientation shall be in an upstream-downstream direction, <br /> parallel with the adjacent river channel except that such orientation shall not be required for utility <br /> transmission lines-permitted by EMC 19.30.370(G),and roads permitted by EMC 19.30.370(M). <br /> C. All new construction and substantial improvements shall comply with the flood hazard protection standards of <br /> EMC 19.30.090. <br /> 19.30.370 Density fringe area: permitted uses. <br /> The following uses are permitted in the density fringe area: <br /> A. Agriculture,including: <br /> 1. Accessory agricultural structures such as but not limited to barns,milking parlors,silos, manure tanks,and <br /> loafing sheds that provide direct support for primary agricultural activities including tilling of the soil, <br /> raising of crops,horticulture,viticulture,small livestock,poultry,pasturing,grazing,dairying and/or <br /> animal husbandry;and <br /> 2. Livestock protection mounds,when the mounds do not consist of solid waste as defined by this title;and <br /> 3. Manure pits and lagoons; <br /> 20 <br /> 126 <br />
