6622-17 - James Canyon Drive Permanent Repairs/James Creek & Little James Creek Stream Res

This project consists of repairing flood damaged roads and creeks in Boulder County. Prior to September 2013 James Canyon Drive was a paved roadway approximately 27 feet wide in the Boulder County foothills with James Creek running along one side. With the flooding event many sections of the roadway were washed away. A 20-foot wide temporary roadway was constructed to carry traffic. Work will consist of constructing a paved roadway including embankment, rockery, retaining walls, permanent drainage structures, signing, striping and construction traffic control. The project is approximately 4.8 miles in length.
 
In addition, the project includes restoration of portions of James Creek and Little James Creek that were scoured and degraded by flooding in September 2013. There will be approximately 6,300 feet of stream restoration work within a 4.4 mile stretch of James and Little James Creeks. The project will increase channel and floodplain complexity through the use of benches and large woody debris to promote sediment storage and habitat development.  The proposed project will use earthwork, in-stream structures, and native plantings to provide flood protection and erosion control. 
 The Contractor will coordinate work during construction with the Engineer and the Stream Restoration Specialist as site conditions are variable.
