Since Ditch C1 captures almost all of the drainage area above the road, <br />very drainage little flows into these culverts. Therefore, no design has been shown. The capacity <br />of each 13" culvert is approximately 5.1 cfs and each 18" culvert is approximately 11.2 cfs. <br />Culvert 129 <br />This 18" CMP will be permanent under BB Road. It is sized for the peak flow from Ditch C24. <br />Attachment 2.05.3(3)-1 Page 38 June 2016 (TR -73) <br />
