Boulder County Commissioners approve two stream improvement projects


From the Longmont Times-Call (John Fryar):

Commissioners Ben Pearlman and Will Toor approved an application by the county’s Parks and Open Space Department and the U.S. Army Corps of Engineers to rechannel and restore riparian and wetland habitat along a stretch of Lower Boulder Creek that runs through county-owned land between 109th and 115th streets northwest of Erie.

Pearlman and Toor also approved the city of Boulder’s application to improve in-stream habitat for native and non-native fish and restore riparian areas on a stretch of South Boulder Creek, a project that includes city-owned Open Space and Mountain Parks properties that extend into unincorporated Boulder County south of U.S. Highway 36 and west of Cherryvale Road.

The county’s project, which still must get final Corps of Engineers approval, would excavate a new, meandering stream channel about 6,400 feet long on the south side of the existing stream channel in which Lower Boulder Creek flows northeast.

Lower Boulder Creek’s existing straight channel through the area was created during past gravel mining operations and earthen levees were built along parts of its banks. That, the county staff reported to commissioners, disconnected the stream channel from its historic floodplain and created “a degraded and impoverished stream environment.”

After the new channel is excavated, Lower Boulder Creek’s current straight channel would be plugged and its path converted to a groundwater-fed wetland.
