Collier Engineering provided investigation, surveying, design, permitting, and construction support to address a worsening sinkhole along Hickory Hollow Terrace. After evaluating the site and existing stormwater system, Collier developed a solution to repair the sinkhole and replace deteriorated drainage infrastructure beneath the roadway. The team also coordinated with Metro Water Services, TDEC, utilities, and other stakeholders to keep the accelerated project moving forward. After construction, the team restored the roadway and sidewalk, while maintaining access and utility service throughout the project.
