Crist Road Widening

  •    •  

Our team provided surveying and engineering services for the widening of Crist Road, which also included replacing ditch flow with an underground drainage system. As adjacent properties developed, the local connector street was built in sections, and once all the tracts developed, a 700-foot gap remained. The City’s goals were to install the final pavement section and complete the storm system to meet current technical standards. During the project, we discovered that two adjacent parking lots had curb openings that drained into a bar ditch being filled with the new road. To overcome this, we provided Y-inlets with aprons and flumes to intercept the flow near the right-of-way line and direct it to the new storm sewer.

As part of the project, we also discovered that the existing downstream storm sewer in Naaman Forest Road was not designed to current City standards. We analyzed and sized alternative storm sewers–one that assumed a free outfall at the downstream connection, and another that accounted for the downstream surcharge. The City elected to install a 100-year system within the project limits only, and postpone any downstream system upgrades to a potential future project.
