In 2022-2023, HMB conducted mist net surveys, capturing 98 bats, including the listed northern long-eared bat, leading to a Biological Opinion from USFWS. Additionally, HMB completed six 404/401 permit applications, documenting stream and wetland impacts and proposing mitigation measures. | Mountain Parkway ExpansionPSAEnvironmentalSecondary Service Areas: Highways & Roads |
 | Bridging Kentucky ProgramPrimary Service Area: EnvironmentalSecondary Service Areas: Highways & Roads HMB has completed archaeological and cultural historic surveys as part of the Bridging Kentucky Program, and performed work continuously over a five year period. The work included cemetery delineations and documentation for KYTC bridge rehabilitations or reconstructions in Districts 1, 2, 3, 5, 6, 8, and 9. Our team surveyed and documented 263 bridge locations, working closely with the State Historic Preservation Office and KYTC to establish field methods and reporting protocols. We performed intensive pedestrian surveys, shovel probing, deep auger testing, and extensive background research. Despite the project's aggressive schedule, our team consistently delivered on time, showing the dedication to delivering quality solutions. | Bridging Kentucky ProgramPSAEnvironmentalSecondary Service Areas: Highways & Roads |
