sedimenr supply will benefit these pres~ntly eroding sites. Consideration should be made of ' containicig the channel somewhat, to protect private and public property. S'~ite 4 is located on Figure 3a, and is a tributary to Fountain Creek that crosses beneath I~ighwa~r 24 and beneath the County Rc,ad adjacent to the Creek. Figure 7 was taken looking upstreani at a headcut maving upstream toward the I-~ighway 24 crossing. Figure 8 was taken looking iiownstream toward Fountain Creek. The gully is generating a significant amount of sedimemt that is contributing to aggradatnon of Fountain Creek. The headcut is in the highway right-of-vray and will eventually endanger the drainage culvert. Headcutting is continuing on the ; opposite side of the highway. Consideration should be given to stopping this erosion. , f Siite 5 is located on Figure 3 a, and is another situation of drainage from Highway 24 right- of-way. Figure 9 shows the drainage mEandering across the undeveloped pasture between the ~ hnghw~y and the County Road. Significant sedimentation is being generated as the flow meanders , arnd in the; headcut moving upstream along the roadside drainage. ~ Site 6 is the County Road bridge crossing site of Fountain Creek, and is located on Figure i 3a. The s~tream bed appears to be aggrada.tional at the site, and banks upstream and downstream ; ~ are erodi:ng, as shown in Fagure 10. Consideration should be given to armoring the raad ~' embankme;nt using stone riprap and to constn~cting an approach section to direct the flow smoothly ~ in$o the btidge opening. ~ Si1:e 7 is also shown in Figure 3a, and is the long reach of Fountain Creek from the County Road brid~;e upstream to Aspen Garden Wa~, near the concrete plant. The entire reach has highly . er~dible banks, some in excess of 20 feet in height. Two primary failure mechanisms were identified along the r~yach: erosion from overbank drainage, and bank failure due to erosion at the toe of t9~e 8 -
