The City of Colton set out to improve the existing infrastructure under two vital county roads that intersect in their community.  Undersized, cast-iron water main and vitrified clay pipe under Minnehaha County Routes 110 and 149 were in desperate need of replacement.  In addition, the City did not have a sufficient water main loop to provide the necessary flows in the event of a fire.  The geotechnical investigation revealed that the soils in Colton were low strength and unstable and thus recommended that all utility trench backfill be replaced and that sub-grade improvements be considered to extend the life of the roadway for two roads that carry significant agricultural and truck traffic.  Banner assisted in determining the most effective sub-grade treatment and found that soil cement stabilization was the most economical solution for the City.  The project also implemented recycled materials.  The existing surfacing and base course were processed-in-place to be reused as base course.  This provided the City significant construction cost savings.  Banner coordinated with SD DENR, BNSF Railroad, Minnehaha County, and the SD DOT to obtain the proper permits and approvals for the project.  Special services Banner provided included assisting the City in procuring additional funding that was necessary for the trench and sub-grade improvements.  Banner also held pre-construction public meetings to inform the public of the upcoming improvements and prepared monthly progress updates for public distribution.
