DESCRIPTION OF WORK
Project purpose: Improvements to and connection of Louis Stephens Drive Extension (SR 1632) from O'Kelly Chapel
Road (SR 1628)/Little Drive (SR 2153) in RTP to Poplar Pike Lane in Morrisville. Also, intersection improvements at Louis
Stephens Drive (SR 1632) and McCrimmon Parkway (SR 1635)
Existing structure: Existing two-barrel structure conveys UT to Kit Creek at 26+00 Lt/Rt. There are no anticipated
improvements to the structure. However, a grass swale ditch will convey stormwater runoff to the stream channel above
the culvert inlet.
IMPACT SUMMARY
Permanent Stream: 15 linear feet of permanent stream impact associated with bank stabilization of UT to Kit Creek.
Temporary Stream: 19 linear feet of temporary stream impact with dewatering to conduct bank stabilization in the dry
at UT to Kit Creek.
Wetland: 0.14 ac of permanent wetland impacts at Site 1 and 0.19 ac of permanent wetland impacts at Site 2. These
impacts are associated with the roadway improvements.
Is mitigation proposed for project?: Yes, mitigation is proposed for wetland only impacts this project. Previous
conversations with Eric Alsmeyer indicate 1:1 mitigation ratio at Wetland Site 1 and 2:1 mitigation ratio at Wetland Site
2.
