B&L was retained to review existing GIS data and establish a Conditions Assessment and Classification system to help automate data collection and inventory the conditions of 65 miles of carriageways within the Minnewaska State Park Preserve and Mohonk Preserve. The inventory task involves aspects of road development including geometric issues, road width, drainage conditions, vegetation management, potential vistas and related structures such as bridges and culverts. B&L collected the data using handheld GPS equipment having sub-meter horizontal accuracy and a two-person all-terrain vehicle.

From this GIS mapping, B&L developed a carriage road naming and stationing convention to assist with documenting work needed on the extensive trail network. After the inventory and analysis was completed, B&L performed an existing systems assessment, cultural resources assessment, maintenance assessment, rehabilitation assessment, and opinion of probable cost. All of this was presented to the client in a Restoration and Maintenance Manual for the Shawangunk Carriage Roads Systems. This manual offers a guide to estimate costs of restoration, reconstruction, and maintenance.
