Left Hand Creek Master Plan

The plan recommends a number of flood mitigation and creek restoration projects that could be implemented with additional funding. Some of these projects have a watershed-wide scope, and others are specific to certain stream reaches. Several potential sources of funding could be used to implement recommended projects.

  • Reach 3B Project Final Notice

    Recently, LWOG received funding to design and implement restoration along Lefthand Creek between Airport Road and Highway 119. The specific elements of this proposed project are to restore this 2,200 foot section of the creek  in order to restore geomorphic function, improve flood resiliency, facilitate restoration of recreational access, and reduce flood risks as outlined in the 2014 Left Hand Creek Watershed Master Plan.  The project will include the following elements:  rebuild floodplain benches/stabilize banks; narrow the active channel, add riffle/pool complexity, and reestablish riparian vegetation; clean excessive sediment at road crossings in particular, and along the entire creek section as required; establish a compound channel, including a low flow channel which will promote appropriate sediment transport and a floodplain to provide conveyance of water and debris during floods; remove sediment and debris from 87th Street bridge crossing, which will enlarge and stabilize the channel and facilitate reopening of the existing bike path underpass that is currently covered in sediment; and perform passive restoration and re-vegetation.

  • Lefthand Canyon Dr Road Closures and Delays

    Lefthand Canyon Dr will be under construction beginning on Monday, Dec. 18 causing road closures and delays.  Central Fedaral Lands, CFL, hired Kelley Trucking to work on the project.  They will reconstruct areas damaged by the 2013 flood and improve the overall safety of Lefthand Canyon Dr.

    Dec. 18 through May 20,  2016, the portion of the road between Old Stage Rd and James Canyon Dr will be completely closed from 8 a.m. to noon and again 12:30 to 4 p.m. Monday through Friday.  Travelers can anticipate 30 minute delays on Saturdays and no construction on Sundays.

    More construction is planned between US 36 and Lickskillet Dr.  This work will happen May 21 through the end of the project in November, 2016.  Boulder County plans for 1-hour delays during the week with no construction on the weekends.

    Boulder County, CFL (a division of the Federal Highway Administration), and Kelley Trucking will host a public meeting on Monday, Dec. 7 to discuss the project.  Residents are invited to learn more and ask any questions regarding the road closures and construction.  The meeting will be held at Altona Grange, 9386 N. 39th St, Boulder from 6 to 7 p.m.

    Boulder County Transportation Director George Gerstle said Kelley Trucking will also construct four bridges and restore portions of Left Hand Creek next to the road to improve the health of the watershed.

    More information can be found on Boulder County’s website.

  • RFP for James Creek Designs

    LWOG is now accepting proposals for James Creek 30% designs.

    This project will provide a 30% design for James Creek reaches 16-1 and 16-2, and a technical review of completed restoration work in reach 18.  LWOG seeks a qualified consultant(s) to assess and develop design documents that will inform future rehabilitation & resilience efforts.  The planning process will build upon relevant prior analyses, utilize or develop modified hydrologic and hydraulic models, and assess the current and desired geomorphic condition to determine the most technically feasible and cost-effective resilient restoration alternative. This work will assess impacts to the stream corridors and develop 30% designs for mitigation of flooding and sedimentation, and the restoration of the stream corridors to a resilient condition.
