Secondary Service Areas: Highways & Roads

HMB performed the I-275 Graves Road Interchange Justification Study (IJS), Phase I design, and environmental design under contract with KYTC and in partnership with Boone County. Three preliminary alternatives were developed: a regular diamond interchange, a partial cloverleaf interchange, and improvements to the existing network. HMB also evaluated enhancements to Graves Road and KY 20, including roundabouts and bicycle/pedestrian facilities. The environmental team provided a comprehensive overview report and addressed potential issues, including viewshed concerns for a historic property. The project proceeded as a design-build, with HMB supporting KYTC through the procurement process, ensuring efficient and thorough environmental services.

HMB was selected to perform key components of The Brent Spence Bridge Corridor Project. HMB assisted KYTC and ODOT by updating numerous environmental documents. The project, in development for over two decades, received $1.6 billion in federal funding in 2022, ensuring its progression to construction. HMB's scope of contributions included:
  • Noise Studies: HMB identified over 1,500 noise receptors, modeled complex layouts, and completed barrier wall analyses within four months, leading to Kentucky's first transparent noise barrier wall.

  • Biological Assessment: HMB obtained Section 7 clearance from USFWS, performing a mussel survey and habitat assessment for listed bats, and expedited the Biological Assessment process.

  • Stream and Wetland Assessment: Conducted assessments for ODOT, summarizing findings for regulatory agencies.

  • Goebel Park Section 6(f) Analysis: Coordinated with KYTC, FHWA, and NPS on documentation and mapping for the 6(f) conversion.

These efforts demonstrate HMB’s expertise in comprehensive environmental services for major transportation projects.

KYTC Noise Screening Tool & Guidance Manual Update

KYTC Noise Screening Tool & Guidance Manual Update

Primary Service Area: Environmental
Secondary Service Areas: Highways & Roads

In summer 2019, KYTC tasked HMB with developing a screening tool to eliminate full highway traffic noise impact analyses for low-level projects. HMB researched policies from other state DOTs, FHWA, and AASHTO, proposing two screening methods: using project-specific values to predict noise levels and measuring distances between noise receptors. After a successful proof of concept, HMB built a user-friendly screening tool and received FHWA approval in May 2020. The tool has saved KYTC significant time and money by streamlining noise analysis processes. Concurrently, HMB updated KYTC's 2015 noise policy, enhancing clarity and revising cost reasonableness criteria. The updated policy was approved and implemented on July 1, 2020.
