Grand Avenue Storm Sewer

West Des Moines, IA

Shive-Hattery provided roadway and utility design, surveys, right-of-way documents, and full construction phase services for a multi-phase roadway and sewer upgrade. Phase 1 involved reconstruction of the Fuller Road/Grand Avenue Intersection and extension of a new storm outfall sewer along Fuller Road. This project received federal STP funding and involved obtaining a categorical exclusion upon securing all environmental clearances including wetlands, archeological, cultural resources and endangered species, Land survey services included boundary surveys and right of way acquisition plats.

Work included relocation of all public utilities; grading; installation of new storm, water and sanitary systems; construction of a retaining wall south of Heatherwood Drive; pavement removal and replacement; and construction of new traffic signals. Intersection improvements involved widening the intersection of Grand Avenue and Fuller Road to provide left turn lanes from each approach. The project also involved hydraulic analysis and modeling of an upstream drainage basin and design of a 72-inch outfall storm sewer along Fuller Road which discharged into Jordan Creek under a separate project.

Phase 2 consisted of reconstructing the roadway from approximately 300 feet north of the Fuller Road/Grand Avenue intersection northerly 0.73 miles to the railroad crossing near Delavan Drive. The FHWA funded project consisted of converting a two lane rural section to a four lane urban section from the Grand Avenue/Fuller Road intersection to an existing bridge over Jordan Creek. This section required relocation of a stream channel to protect the widened roadway from damage from the previously migrating stream channel. It also required use of a modified urban cross section to limit earthwork requirements and to minimize impacts to adjacent properties.
 
The project also consisted of reconstructing and widening a four lane urban section to a five lane section from the bridge over Jordan Creek northerly to the railroad crossing. Construction of a multipurpose trail along this segment of the project crossing under the bridge at Jordan Creek was also included.

Phase 3 used STP Funds to reconstruct a 1.5 mile conversion of a two-lane rural roadway to a five-lane urban section. The project extended along a variety of land uses including developed and undeveloped residential properties, industrial areas, and commercial zones. A particularly challenging aspect of this project involved design of the new urban section adjacent to an existing rural section. The adjacent property had experienced drainage problems, which were complicated by the proposed urban cross section that was to be raised by an additional four feet. The ultimate solution was to shift the roadway alignment to accommodate the geometric and profile changes. Services included design of grading, paving, drainage systems, storm sewer, a box culvert and intersection improvements.
