minimum building opening. This is more restrictive than what is required by RCWD <br />Rule, as shown in Table 5.1. However, if this three-foot freeboard requirement is <br />considered a hardship, the standard could be lowered to two feet if certain conditions <br />can be met. Table 5.1 shows the requirements of the RCWD with regard to low floor <br />and low entry freeboard requirements. Atlas 14 rainfall data shall be used to calculate <br />the 100-year high water elevation. <br />Table 5.1 Hugo Requirements for Low Floor and Low Entry Freeboard Requirements <br />Freeboard <br />Regional Flood <br />Detention Basins, <br />Infiltration and Biofiltration <br />Rain <br />Elevations <br />Wetlands & <br />Basins <br />Gardens <br />Stormwater <br />Ponds <br />100-yr <br />EOF <br />100-yr <br />EOF <br />Bottom <br />100-yr <br />EOF <br />EOF <br />Low Floor <br />2.0 ft <br />1.0 ft <br />0.0 ft <br />NA <br />0.0 ft <br />NA <br />NA <br />NA <br />Low <br />3.0 ft <br />NA <br />3.0 ft <br />1.0 ft <br />NA <br />3.0 ft <br />1.0 <br />0.5 ft <br />Opening <br />ft <br />6. Wetlands will be protected within the City boundaries to assure that the value of <br />wetlands in relation to their surface water quantity benefits are not impacted. Where <br />appropriate and feasible the City will support the improved function and value of <br />degraded and drained wetlands in order to provide increased water quality treatment, <br />flood attenuation and storage, plant diversity, and wildlife, fisheries, and amphibian <br />habitat. <br />7. The City will identify and manage landlocked basins to minimize flooding and <br />preserve the natural hydrology of landlocked basins in accordance with RCWD Rule <br />C.5(e), BCWD rule 2.4.1(a), 2.4.1(b) and 7.3.1, and CMSCWD Rules Policy 7.1.4. <br />8. The City will require compensatory storage equal to the storage losses resulting from <br />floodplain fill. Floodplain elevations within the RCWD will be based on RCWD's flood <br />models and the associated regulatory flood elevations. All floodplain permitting <br />activities shall be subject to RCWD, BCWD, or CMSCWD rules. <br />9. The City will require that the peak rate of runoff for any area that drains to Brown's <br />Creek be limited to the pre -settlement rate of runoff when it is deemed reasonable <br />and feasible to do so. <br />10. The City will require that those areas within the CMSCWD be required to a <br />stormwater discharge rate equal to pre -development rate and volume as calculated <br />by the approved curve numbers for upland areas. <br />11. The City will implement the use of the RCWD flood models and associated regulatory <br />floodplain elevations to enforce freeboard requirements and floodplain alterations. <br />12. The City will ensure no net loss of flood storage capacity. To that end, no person <br />shall alter or fill land below the 100-year flood elevation of any waterbody, wetland, or <br />stormwater management basin or place fill in a landlocked basin without first <br />obtaining a permit from the appropriate jurisdiction. <br />5.5.

Goal <br />The City of Hugo will protect and manage wetlands in conformance with the requirements <br />of the Wetland Conservation Act of 1991 and RCWD Rule F. <br />SECTION 5 <br />
