Short Milne Property Wetland Delineation and Rare Plant Survey, City of Boulder Open Space and Mountain Parks
On the City of Boulder Open Space and Mountain Parks (OSMP) Short Milne property, the September 2013 flooding caused a breach in the bank of an adjacent gravel pit pond, re-alignment of Boulder Creek, and blocked flow to the Green Ditch. Temporary repairs were made in the spring of 2014. Prior to beginning permanent repairs, OSMP hired AEC to complete a wetland delineation and rare plant survey of the complex, 60-acre parcel. Following completion of the delineation and rare plant survey, AEC prepared a Wetland Delineation Report and Rare Plant Survey Report per USACE and US Fish and Wildlife Criteria, respectively.
North Clear Creek Sediment Removal and Channel Restoration, Clear Creek Watershed Foundation, Gilpin County
During the September 2013 flooding, crusher fines and associated sediment from a quarry were released into North Clear Creek via a steep, unnamed tributary. The Clear Creek Watershed Foundation (CCWF) managed removal of 2,500 cubic yards of crusher fines and restoration of approximately 0.45 acre of the creek channel. Auckland Environmental Consulting (AEC) completed a wetland delineation, USACE coordination, and Section 404 permitting.
