1. The Jordan River Erosion Hazard Area (JREHA) is delineated in Figure 25.4 and is based upon the Meander Corridor in the Jordan River Corridor Preservation Study by CH2MHill dated March 2007. Bank stabilization methods may be implemented to remove property from the Jordan River Erosion Hazard Area as identified in this section.
2. Bank Stabilization Measures. Development within the JREHA shall be protected by engineered channel stabilization measures. Such measures may include hard structural features like concrete, rip rap, geotechnical materials, or gabions. These measures may also include bioengineering techniques that use natural materials and harness natural river processes. The following are design requirements for bank stabilization measures.
a. Adverse Impact. Development and bank stabilization within the JREHA shall not create adverse impacts on any adjacent property. An engineering hydraulic and hydrologic analysis shall demonstrate that the proposed improvements will not increase the scour/erosion conditions on neighboring parcels.
b. Replacement of Bank Vegetation. Bank and floodplain vegetation disturbed by construction shall be replaced or enhanced with species acceptable to the Division of Forestry, Fire, and State Lands (Forestry Fire & State Land).
c. Bank Slope. Vertical or steep channel banks shall be regraded to flatter, more stable slopes. In general, bank slopes of 2.5:1 or flatter are required to be stable and support vegetative growth.
d. Toe-Down. Structural measures shall be adequately toed-down below the design scour depth, which shall include consideration of the long-term scour depth. Alternatively, grade control can be provided to limit long-term scour.
e. Overtopping. Bank stabilization measures that do not contain the 100-year flood shall be designed to withstand overtopping as well as flow on the lee side.
f. Bioengineering. Toe protection shall be required to assure proper function of bioengineered bank stabilization measures, given the potential for toe erosioninduced bank failures in the study reach.
g. Bank stabilization measures shall be reviewed and approved by Utah Forestry, Fire, and State Lands, Army Corps of Engineers, and any other governmental agency with jurisdiction over these areas.
