<br />3. The improvements to Barnum Lake and the channel and crossing <br />improvements from the Platte River to Federal Blvd. must be <br />constructed as a unit, since the improvement of Barnum Lake <br />will direct more flow down Weir Gulch than presently. <br />If Barnum Lake is improved without the downstream improve- <br />ments suggested, the possibility exists that suit might be <br />lodged by any downstream resident for damage due to the <br />increase of runoff along the existing channel route. <br /> <br />SOUTH WEIR GULCH <br /> <br />1. Flood plain zone areas subject to inundation by a 100 year <br />storm to prevent further channel encroachment. <br /> <br />4. The Federal Blvd. Detention Reservoir should be started and <br />the base facilities constructed. Additional storage capacity <br />should be developed in the reservoir as uses for the earth <br />removed from the reservoir occur. <br /> <br />2. The proposcd improvcmcnts are relatively low priority. <br />The existing broken concrete riprap chute must be kept in <br />good repair to prevent total failure and significant <br />erosion. The suggested improvements may be postponed until <br />fill material becomes available or until the area is developed <br />as a park. <br /> <br />5. The following areas of channel and crossing construction <br />are essentially the same in priority. <br /> <br />A. !looker St. TO Bryant Ave. <br /> <br />B. Virginia Ave. to Wolff St. <br /> <br />C. Ohio Ave. to Harlan St. <br /> <br />D. Mississippi Ave. to Kipling St. <br /> <br />E. Sheridan culvert. <br /> <br />F. Alameda Ave. culvert. <br /> <br />6. Development of the area from Alameda Ave. to Virginia Ave. <br />and from Wolff St. to Sheridan Blvd. should be considered <br />a Parks Department development since their construction is <br />not essential to the overall drainage system. <br /> <br />NORTH WEIR GULCH <br /> <br />1. Flood plain zone areas subject to inundation by a lOO year <br />storm to prevent further enoroachment on the flood plain. <br /> <br />2. Revise the area where North Weir Gulch enters Main Reservoir <br />to assure that all flow goes directly into the reservoir. <br /> <br />3. Other improvements along the gulch are relatively low priority. <br />Channel construction may await fill material becoming avail- <br />able or possible development as a park by the Parks Department. <br /> <br />4. The enlarged conduit bencath Union Ave. indicated on the <br />master plan may not be necessary, since the existing capacity <br />of the conduit beneath the street is sufficient to pass <br />approximately the 7 year storm. <br /> <br />-122- <br /> <br />-123- <br />
