Bank stabilization for the Master Plan alignment and the mini- <br />mum maintenance alignment will be in accordance with those <br />methodologies presented in Section 2.3 - Riverbank Protection. <br />For the Master Plan alignment, the various acceptable types of <br />bank stabilization are presented in the Master Plan drawings <br />and differ slightly from the requirements specified in Section <br />2.1 - Types of River Alignment and 2.2 - Revegetation of Berms. <br />The principal differentiation is in the required stabilization <br />scheme. In most cases, where the Master Plan alignment de- <br />viates from the requirements specified, the areal extent of the <br />recommended slope stabilization scheme will extend beyond those <br />required if the minimum maintenance alignment were adhered to <br />rigorously. <br />Ffien the alignment of the South Platte River conforms to either <br />the recommended Master Plan alignment or the minimum mainten- <br />ance alignment, the minimum allowable top width without pitside <br />bank protection will be 200 feet. This top width presumes that <br />the river banks will be stabilized by the owner in accordance <br />with the requirements specified in the Master Plan or as part <br />of the minimum maintenance alignment. <br />When the requirements of the Master Plan alignment or the mini- <br />mum maintenance alignment are adhered to and, in addition to <br />complying with the requirements for river bank stabilization, <br />the pitside slope of civerside berms are stabilized in accord- <br />ance with Section 2.4 - Pitside Bank Protection, the minimum <br />allowable top width for riverside berms will be 100 feet. <br />2.7 $ERM TOP WIDTH-LATERAL BERMS <br />This section specifies the minimum top width for lateral berms located <br />adjacent to the South Platte River and oriented perpendicular to the <br />river.
