Basin II <br /> <br />As with the previous basin, it is recommended to improve the <br />existing ditches to carry stormwater to the Rio Grande River as <br />the areas develop. This vacant area is planned for development <br />in the near future. The area should be filled'and graded to <br />alleviate the ponding problem that presently exists. The three <br />streets (Clark Street, Wolf Street, and Oliver Avenue) should <br />have larger inlets installed that either connect to a new pipe <br />system or are connected to the old system. For conveying the <br />water away from this area, there are two alternatives. <br /> <br />Alternative 1. Connect a new storm sewer system from Wolf <br />Street and Oliver Avenue to the existing system at the cor- <br />ner of Clark Street and Duke Drive with an l8-inch pipe. <br />Approximately 800 feet of l8-inch diameter pipe, inlets, <br />and cross-pans would be installed to collect and chanel- <br />ize the stormwater. This alternative eliminates only a <br />small percentage of the ponding problem because the 18- <br />inch diameter pipe has a 3 cfs capacity. <br /> <br />Alternative 2. Install a new 48-inch line from the corner <br />of Clark Street and Douglas Drive, east in Clark to the <br />Rio Grande River, and from Wolf Street and Clark Street to <br />Wolf Street and Oliver Avenue. Some of the lines from the <br />existing system can be connected to this new line. <br /> <br />System Improvements <br /> <br /> Pipe Pipe <br /> Size Length <br />From To (inches) (feet) <br />Intersection of Douglas Rio Grande 48 2,200 <br />Drive and Clark Street River <br />Intersection of Oliver Above line 36 575 <br />Avenue and Wolf Street <br /> <br />-36- <br />
