NEWS AND UPDATES...

Starting Monday, August 17, 2020, the City and County of Broomfield and their contractor, GoodLand Construction, will begin construction on the Quail Creek Channel Improvements at Broadlands project.  Construction is expected to be complete in November 2020.

Council approved a construction agreement for the Quail Creek Channel Improvements at Broadlands project with GoodLand Construction on June 23, 2020.  The project will pipe a section of the Westlake Lateral to limit the amount of flow entering the irrigation ditch, and regrade the area so excess flows will run into Quail Creek drainageway as originally contemplated rather than into the Westlake Lateral irrigation ditch. This project will eliminate the flooding concerns of adjacent residential properties and erosion issues through the drainageway/irrigation ditch.  Staff is currently working with Broomfield and FRICO to ensure all paperwork, including permits, bonds and insurance, are in order for construction to commence.  

BACKGROUND

When the Broadlands subdivision and Broadlands Golf Course were originally built, the area was graded such that Quail Creek drainage flows are routed into the Westlake Lateral irrigation ditch just upstream (northwest) of the Sunnyslope subdivision, rather than into the Quail Creek drainage way in the Broadlands Golf Course.

The Westlake Lateral overtops with the additional storm flows and has caused erosion and flood damage to adjacent properties along Creek Drive in the Sunnyslope subdivision, and damage to the irrigation diversion structures.

Affected residents have contacted the City Council and the City and County Manager’s office on several occasions concerned about flood damage.

Broomfield has a large sanitary sewer line that runs parallel to the ditch that is at risk with continued erosion. The sewer main serves over 1,000 homes in the Aspen Creek, Broadlands, Country Estates, Sunny Slope and Whistlepig subdivisions.

Broomfield staff have been working with the Farmers Reservoir and Irrigation Company (FRICO) since 2016 to develop a solution and agree to maintenance terms of this section of the Westlake Lateral.

FRICO has recently approved the design plans and a construction and maintenance agreement for the project.

The proposed project will pipe a section of the Westlake Lateral to limit the amount of flow entering the irrigation ditch, and regrade the area so excess flows will run into the Quail Creek drainage way as originally contemplated rather than into the Westlake Lateral irrigation ditch.  The project will eliminate the flooding and erosion problems noted above.

The project also includes modifications, removals, and repairs to the existing irrigation diversion structures and construction of a maintenance access path.
