DEL-42 Emergency Culvert

This project consisted of emergency repairs for a large sinkhole that had developed at the existing culvert location due to heavy rainfall. 2LMN prepared plans based on ODOT’s hydraulic analysis for a replacement 120” CMP pipe with a paved invert and designed solider pile and lagging walls for the inlet and outlet of the culvert. In addition, 2LMN designed a full height headwall at the outlet of the culvert to minimize its overall length and alleviate the need for additional right-of-way acquisition. Adding to the complexity of this project was the need for the Greenwood Lake Dam to be decommissioned. Therefore, 2LMN provided survey services at various times to record the removal elevations of the stacked stone half-moon riser at the inlet of the dam as the water elevation of the lake was allowed to slowly dissipate. At the close of the project, 2LMN provided final as built survey elevations to serve as part of the dam decommission records for ODNR.
