Ciorba provided preliminary and design engineering services to reconstruct 3,000 feet of Helen Road (from Cedar Avenue to Plum Grove Road). We developed conceptual alternative cross sections for the roadway and presented them at a neighborhood public meeting. Local residents were concerned that the improvements would promote “cut-through” traffic. Other concerns raised were on-street parking restrictions and localized flooding problems.
After approval of the proposed roadway cross section, we prepared the design plans, specifications, and cost estimates. Construction was paid for with Motor Fuel Tax funds.
Improvements consisted of replacing the narrow two-lane rural roadway with a new 30-foot wide bituminous pavement with curb and gutter. We developed a new roadway profile to improve pavement and parkway drainage. To alleviate local flooding, our design plan included the construction of a new storm system to replace the existing ditches and culverts. We designed the storm sewer to allow for future connections to collect additional runoff from nearby flood prone areas.
