Design and Construction Program Notes
Paul Hindman, P.E., Manager, Design and Construction Program

In 2005, the Design and Construction program continued to assist local governments in designing and building many major flood control projects. Internally, we divide the responsibilities amongst our staff by political boundaries. Laura Kroeger is in charge of Boulder, Adams and Broomfield Counties, Ken Mackenzie is responsible for Denver and Jefferson Counties, and Paul Hindman watches over Douglas and Arapahoe Counties.

Throughout the entire program, in 2005 we committed 6.8 million to projects. As shown in the attached table, the Design and Construction Program continues to manage over 80 projects. Some have been ongoing for many years with multiple phases while others are just getting started.

A couple of projects deserve special recognition. One of those is the Littles Creek project in Littleton. Laura Kroeger, the District’s Project Engineer assigned to the Project, was responsible for administering the construction aspects of the project. This was the third phase of improvements to Littles Creek (between Broadway and Apache Road) that Urban Drainage and the City of Littleton teamed up with engineers from ASCG, INC. and constructors from Flatiron Constructors, Inc. to improve the drainageway along the center of Sterne Parkway in Littleton. The $703,000 project lasted six months and was completed in September.


Littles Creek at Apache Road

Following completion of this last phase, all structures between Elati Street and Apache Road will have been removed from the 100-year floodplain. The first two phases in the project consisted of replacing the bridges of several street crossings, and of course, channel improvements. Phase 3 focused on collecting the upstream storm water plus the local storm sewer flows into a 100-year crossing under Sterne Parkway. It was designed with a three-sided precast box and a cast-in-place slab & low-flow channel, several storm sewer improvements ranging from 18" to 48" RCP, and a new intersection with curb, gutter and sidewalk. Amcor produced the 175 linear feet of 28' wide by 5' high side boxes while Flatiron used a 300-ton hydraulic crane to place the boxes (see photo). Notably, the boxes were placed in less than two days without complication.

The second project of note for 2005 was the Tennyson Street Bridge across Lakewood Gulch. Ken MacKenzie oversaw this project for the Urban Drainage and Flood Control District who partnered with the City and County of Denver to complete yet another flood control project on Lakewood Gulch. This was the third bridge replacement along the gulch and was completed in July of this 2005. To see this 1.7 million dollar project a success, civil engineers and landscape design specialists teamed up from select consulting firms such as Kiowa Engineering, Bates Engineering, and Design Concepts. The single span bridge replaced a 7' by 6' box culvert, and has the capacity to pass the 100-year flood. The bike trail parallels Lakewood Gulch underneath the bridge, eliminating the on-grade crossing currently in place. Also, the channel was lined with grouted flagstone, a definite compliment to the surrounding area. This feature is just another part of the new improvements Design and Construction continues to test out in the Denver area.
