This solution will <br />solve the most flooding problems with one major line and <br />four lateral lines that will take the runoff eastward to <br />the Rio Grande River. <br /> <br />2) Flapgates should be installed on all existing and proposed <br />lines that drain directly into the Rio Grande River to pre- <br />vent backflow problems that have occurred to date. <br /> <br />3) Other recommended solutions outlined in Basins I-VI should <br />be implemented as soon as funding allows, taking into con- <br />sideration such items as availability of contractors, staff <br />requirements, acquisition of land and right-of-way, etc. <br />Priorities may change from the Engineer's listing of solu- <br />tions, depending on many of th~ items mentioned above. <br /> <br />4) Drainage studies should be conducted for each new develop- <br />ment in order to ensure that the volume of runoff will not <br />overload the city's existing or planned storm sewer system. <br /> <br />5) This drainage plan should be used as a planning tool for <br />the City and County of Alamosa for planning future develop- <br />ments and improvements to the existing storm sewer system. <br /> <br />6) Additional studies should be funded by federal and state <br />agencies to evaluate alternatives for protecting the com- <br />munity from flooding by the Rio Grande River, a topic not <br />addressed in this study. <br /> <br />7) Additional survey data should be obtained during the final <br />design of storm sewer facilities to distinquish curbs and <br />gutters, street cross slopes, sump locations, specific <br />driveway details, etc. <br /> <br />-9- <br />
