The City of Hillsboro saw the need for a new residential housing development and hired AE2S to design new underground infrastructure and street construction for the new Riverbend Addition. The project consisted of a new sanitary lift station, new water and sewer utilities systems, the construction of new curb and gutter with a bituminous street surface, and new street lighting. The bituminous street section consisted of a 12” aggregate base course, geotextile fabric, drain tile tied into storm sewer to ensure adequate subsurface drainage, and 4 ½” of asphalt pavement. Approximately 2206 lineal feet of reinforced concrete (RCP) storm sewer was placed in this project. To accommodate the new ditch regrading, shaping, and drainage associated with the East Side drainage project, dual 36” RCP culverts were placed under the two new approaches to the Riverbend Addition.

AE2S was retained to perform an in-depth stormwater management plan as well as an extensive analysis of site earthwork quantities for an initial area of the Urban Plains development in Fargo, ND. HydroCAD and XP-SWMM models were set up to replicated existing/proposed topography, soils, anad land use. A detailed topographic survey was conducted to assess site earthowrk quantities and ground elevations. This data was used to create digital topographic models of the existing and proposed surfaces.
