KDOT Access Management Policy
4.4.10 Drainage considerations
Drainage pipes used in KDOT’s R/W should meet KDOT’s Pipe Policy, dated July 11, 2008, or the
current version. The Pipe Policy provides information on the different pipe types and when and
where they may be used based on differing soil conditions. The policy may be found at
http://www.ksdot.org/burlocalproj/BLPDocuments/KDOT_Pipe_Policy.pdf.
In addition, the most recent version of KDOT’s Drainage Design Manual should be used for all
aspects of drainage design with respect to access, especially in sizing drainage pipes. The Drainage
Design Manual may be found at http://kart.ksdot.org/.
Access points must be designed and constructed so that they do not adversely affect drainage
of the highway or adjacent properties. The drainage and the stability of the highway sub-grade
must not be impaired. In no case may the construction of an access cause water to flow across the
highway, pond on the shoulder or ditch, or result in erosion within the highway R/W. In order to
prevent drainage from the access flowing onto the roadway, the profile of the access can be
designed to accommodate either uphill or downhill grades from the roadway to the access.
Drainage collected by ditches, gutters, or pipes on private property will not be discharged into the
highway drainage system unless expressly approved by KDOT. The owner may be required to
submit a drainage report to KDOT, justifying the drainage system proposed and the pipe or storm
sewer size to be used.
4.4.10.a Curb and gutter
Where drainage is carried along an existing highway curb and gutter, the access will be constructed
with a short rise in elevation to prevent runoff from spilling into private property. The flow line of
the highway gutter through the access must be restored. Where curbs are cut for the construction of
access, the entire curb and gutter section must be removed. Removal of only the raised portion of
the curb and then paving over the broken section will not be allowed. Design details for curb and
gutter (Type I, Type II and Type III) are shown in Figure 4-59. Gutter details are given in
Figure 4-60, and protection curb details are shown in Figure 4-61. City details for curb and gutter
may be used as approved by the District Engineer.
KDOT curb & gutter guidelines should be used on curb & gutter sections. On City Connecting
Links (CCL), city standards may be substituted as approved by KDOT.
