Reach 3 Projects

Reach 3 starts at Airport Road in Longmont, and goes west to US 36. This reach is primarily rural, although the St. vrain Creek interacts with the existing sand/gravel mining sites and irrigation ponds. During the flood, large split flow paths cascaded through the reclaimed gravel mining ponds. One split channel resulted in flooding outside of the 100 year floodplain and affected neighborhoods downstream in the City of Longmont.

St. Vrain Creek Restoration – US 36 to Airport Rd
The project in this area, known as “Reach 3” or “The Breaches”, is being managed by Boulder County Parks and Open Space (BCPOS), who hired a consulting team led by Engineering Analytics. The design portion of the project is funded by the Colorado Department of Local Affairs (DOLA) Community Development Block Grant – Disaster Recovery (CDBG-DR). The project team is currently working on developing construction-ready designs.

The construction phase of the project is estimated to begin in 2017 and will be funded by Boulder County, the Natural Resources Conservation Service (NRCS) Emergency Watershed Protection Program (EWP), and the Colorado Water Conservation Board (CWCB).

The SVCC and our stakeholders have provided a number of comment letters with feedback on the project to Boulder County Parks and Open Space. You can find those letters below:

Pella Crossing Reconstruction
Pella Crossing Recreational Area, owned by Boulder County Parks and Open Space, has a special place in many people’s hearts – many loved to fish, hike, view wildlife, and relax at Pella Crossing before the floods. The reconstruction of Pella Crossing began in September 2016, and is expected to be complete by Spring 2017. Boulder County plans to fix the breaches between the ponds, rebuild the trails, and restore the trailhead. This approximately $3M project is being funded by FEMA, the state, and Get Outdoors Colorado (GOCO).
