<br />Coon Creek - There are three on-stream reservoirs on Coon Creek that help to reduce the <br />flood peaks in their immediate vicinity. These are Grant A Lake, Beer Sisters Lake, and an <br />unnamed reservoir at the upstream study limit. <br /> <br />Lena Gulch - Channelization has been completed through the Den ver West Office Park. The <br />improvements are sufficient to provide protection for the office buildings in this area. <br /> <br />Lena Gulch Tributary - Channel improvements have been constructed from approximately <br />the mouth upstream to Pike Street. Good flood protection is provided to residences in this <br />area. <br /> <br />Leyden Creek - Leyden Lake, located just upstream of Indiana Street, provides some storage <br />routing during flood events. The 100-year peak discharge is reduced from 3,750 cfs to <br />2,200 cfs downstream of the lake. <br /> <br />Lilley Gulch - There is one small reservoir just downstream of South Kipling Street and <br />several places where ponding could occur behind road embankments. However, these areas <br />do not provide enough storage to significantly affect the peak discharges. <br /> <br />North Branch Coon Creek - An unnamed reservoir located just upstream of South Simms <br />Street provides little flood peak reduction. <br /> <br />Ralston Creek - Ralston Reservoir, located west of State Highway 93, provides some storage <br />routing during flood events. Blunn Reservoir is inoperative, but may provide additional flood <br />protection in the future. <br /> <br />SJ CD 6100 - Webster Pond, located just upstream from Webster Street, provides some flood <br />storage area, but has a minor effect on the peak discharges. Channel improvements have been <br />constructed between Lamar Street and Pierce Street, which provide good flood protection in <br />this area. <br /> <br />SJCD 6200 North Tributary - Channel improvements have been constructed between Ken <br />Caryl Avenue and South Kendall Boulevard, and a storm sewer has been installed between <br />Ken Caryl A venue and Platte Canyon Road. These facilities provide a moderate degree of <br />flood protection in this area. <br /> <br />Troublesome Creek - There are several small on-stream ponds that have a negligible effect on <br />peak discharges. <br /> <br />Van Bibber Creek - Channel improvements have been constructed along the north side of <br />West 58th Avenue. <br /> <br />Van Bibber Tributary - Ramstetter Reservoir, which is located at the upstream end of the area <br />studied, near State Highway 93, provides minimal routing effect to the peak discharges. <br /> <br />In the City of Arvada, flood protection measures on the study streams consist primarily of <br />channelization projects and improvements to a number of important bridges. Future <br />protection measures on the streams were designed, as outlined in the UDFCD plans entitled <br /> <br />22 <br />
