Prairie Parkway Street Expansion

CGA was retained by the City of Cedar Falls to provide survey, traffic and roadway analysis, and design of a 4-lane boulevard street extension 3/4 of a mile in length that includes a roundabout for future street connections.  A SWPPP, storm water management plan, and construction staking were also included in the project.

CGA conducted a traffic analysis in order to assist the City in determining the desired street section, i.e. two-lane, three-lane with center turn lane, four-lane, four-lane boulevard, etc.  CGA utilized existing available traffic reports and traffic volume counts for this analysis.  CGA also conducted an analysis on a future intersection midway through the corridor in order to determine which type of intersection would operate most efficiently.  A detailed traffic report was prepared and submitted to the City which concluded that a four-lane boulevard with a two-lane roundabout intersection was most efficient for the extension.

The design consisted of 3/4 of a mile of four-lane boulevard matching into an existing roundabout on the south and an existing 4-lane boulevard on the north.  A 120 foot radius dual lane roundabout was designed in the middle of the corridor to provide for a future cross street to be intersected with the proposed street.  This project included storm sewer design and a detailed storm water management report was prepared along with a SWPPP.
