• CULVERT 117 <br />This culvert will be permanent under BB Road at the Sunshine Ranch Corner. It will handle the peak <br />flows from Ditches C12 and C13. This is a combined peak flow of 38.8 cfs. A 36" CMP is needed. <br />CULVERT 118 <br />This culvert carries the peak flows from Ditches C1 And C2 under the BB Road. It is temporary until <br />reclamation is approved and the ditches will be removed. <br />CULVERTS 119-128 <br />These culverts are 13" x 17" arched culverts of 35 feet length which are placed along the BB Detour <br />Road as required by the County. Since Ditch C1 captures almost all of the drainage area above the <br />road, very little drainage flows into these culverts, therefore, no design has been shown. The <br />capacity of each culvert is approximately 3.4 cfs. <br /> <br />CULVERT 129 <br />This 18" CMP will permanently carry the drainage from Basin 13 under the reconstructed BB Road. <br />It is sized fore the peak flow of 4.1 cfs from Ditch C24. <br />• xav~sEDmnxcxzooe Attachment 2.05.3(3)-1-77 <br />
