These engineering drawings prepared by Herbert, Rowland and Grubic, Inc. for the Dauphin County Board of Commissioners detail the Race Street Improvements Project located in Millersburg Borough, Pennsylvania. The project involves full depth reconstruction of Race Street, including roadway improvements, ADA ramp installations, curb replacements, and associated infrastructure upgrades. The design documents cover multiple street intersections including Race Street, Pine Street, Plum Street, Union Street, Cherry Street, and Center Street, with specific focus on roadway geometry, drainage, and accessibility enhancements.

The technical drawings provide comprehensive details for road reconstruction, including typical sections showing pavement base course, asphalt mixture design, geotextile placement, and erosion control measures. The project incorporates several critical elements such as compost filter socks for sediment control, ADA compliant curb ramps at multiple intersections, and careful consideration of existing utilities and property boundaries. Specific technical specifications include 6-inch subbase depth, various asphalt mixture layers, and precise elevation measurements to ensure proper drainage and alignment with existing infrastructure. The documentation suggests a holistic approach to street reconstruction that balances engineering precision with environmental considerations and accessibility standards.
