Cross Drain Location and Size
There are several sections where the capacities of the road side ditch conveyance are limited. Six
CSP cross drains (Nos. 1, 2, 4, 5, 6, and 9) were located, modeled and sized just up-gradient of
. these low capacity sections. The purpose of these cross drains is to route storm water from the
road side ditch to the trunk line, or to the main channel that is located on the other side of the
road. Four minor cross drains (Nos. 3, 7, 8, and 10) were also designed for draining storm water
from depression spots. The discharges flowing through these cross drains are minimal (estimated
less than 1 cfs). Therefore, these minor cross drains were designed based solely on site conditions
and not modeled by using SEDCAD 4. Cross drain data are listed in Table 6 and shown on Plate
I. Refer to the Tune 2005 Design Plans, Sheets SS-2, SS-3, and DR-1 to DR-5.
