Centennial Trail Culvert Repairs

Wade Road to Hilltop Road:

Notice 9-28-17:

Approximately 100 lineal feet of the Centennial Trail between Wade Road and Hilltop Road will be closed to all users with no access from the north or south on Wednesday, October 10, 2017 between 8:30 am and 4:00 pm for the purpose of conducting a geotechnical investigation for culvert repair

Background:

In January 2017 a culvert conveying a small un-named creek under the Centennial Trail collapsed causing a sinkhole extending from the trail surface down to the pipe. The hole has been temporarily filled with gravel and the area secured with fencing closing one lane of the trail along with equestrian trail section.

Action:

Parks has hired a Consultant to perform investigative work including a geotechnical investigation, critical areas study and drainage review, followed by preparation of construction documents. This project will require several permits which may be seasonally sensitive. Construction repairs of this section are likely not to occur until Summer 2018 and will require several days of trail closure.

Update 9-28-17:
Video work of the other eight culverts along this section of trail was performed under the consultant contract. One additional culvert showed signs of failure so additional investigative work requiring closure of trail is necessary; five other culverts require joint repair or linings.
