This project is the single largest flood control
project ever undertaken by the Urban Drainage and Flood Control District,
and/or the City and County of Denver and represents state-of-the-art water
resource engineering. When completed, this project will remove 320 acres
of land within north Denver from the 100-year floodplain.
This project has been divided into three (3) separate final design and
construction phases. Phase I, which was completed in May 1997, constructed
2,000 linear feet of channel improvements including flood levees, greenway
trails, bank stabilization, aquatic and wildlife habitat improvements,
landscape plantings, and the removal of a large abandoned sanitary sewer,
which bridged the river.
Phase II, completed in August 1998, included construction of additional
floodwalls and flood levees, bank stabilization, greenway trails, aquatic
and wildlife habitat, and landscape plantings.
The Phase III construction (Fall 2005 thru 2008) included the removal of the Burlington Ditch /O’Brian diversion dam
downstream of Franklin Street. These ditch facilities irrigate over
100,000 acres of land and are the facilities that fill Barr Lake. This
project includes the construction of a diversion approach channel and box
culvert, a new diversion dam with boat landings upstream and downstream
for safety purposes and the construction of a fish ladder over the new
diversion dam.
Also included are the construction of grade control weirs, the construction of the Franklin Street trail underpass, the
construction of a new pedestrian bridge, removal and replacement of the
Union Pacific Railroad (UPRR) bridge downstream of Franklin Street, and
removal, relocation of a 42-inch live sanitary sewer and reconstruction of the 36-inch Denver Water Department water
line. In addition, this project incorporates construction of scour
protection for the project at the Franklin Street bridge, aquatic and
wildlife habitat improvements, and appurtenant facilities.
404 Permitting, regulatory permitting, and FEMA floodplain submittals have
been key parts of this project. |
