S. Sherman storm drainage work starts next week

Starting next week, Fort Morgan residents can expect traffic disruptions along South Sherman Street as construction work begins on a storm drainage project, according to a city news release.

Work will start Sept. 2 on the project, which will construct a storm drainage system along five blocks of South Sherman. It will continue at least through Oct. 31, as will the related traffic disruptions, the release stated.

The project is part of the city's storm drainage master plan. It resulted from a drainage study and design completed in 2011 for the south quadrant of the city.

The new drainage system will intercept a large portion of surface runoff water coming from West Street before it is conveyed into Burlington Avenue.

This project will not result in a full curb-to-curb resurfacing of South Sherman, which would far exceed the budgeted funding. The areas excavated during the project will be backfilled and resurfaced, but the aim of the project is storm drainage improvement and not primarily road resurfacing.

Partial funding of the estimated $810,000 project is through the Colorado Department of Local Affairs Energy & Mineral Impact Assistance Fund, matched with city capital improvement funding. Edge Contracting Inc. of Golden will perform the work.

The project will create a north-south connection to an existing 66-inch storm pipe that runs east-to-west across South Sherman and moves water to retention east of the city. Approximately 1,500 feet of concrete storm sewer piping, varying between 18-inch and 36-inch diameters, and 1,000 feet of 29-by-45-inch elliptical concrete pipe will be installed, along with associated inlets and manholes.

Construction will require concrete pavement saw-cutting, removal and replacement, as well as curb ramps to comply with the Americans with Disabilities Act and some sidewalk replacements and curb and gutter replacements. The storm drainage improvements will require excavation and pipeline installation depths varying between 2 feet and 18 feet.

Because of the expected traffic impacts, city officials ask residents to be patient and avoid South Sherman Street whenever possible during the project, the release stated.

Detours and extensive traffic control signage will be placed on Sherman and adjacent streets throughout the construction period.
