Appendix I - Historical Drawings 5-15-24.pdf

Appendix I is a set of historical drawings prepared by Wade, Trim & Associates, Inc. for the Wayne County Department of Public Services, related to the North Huron Valley-Rouge Valley Wastewater Control System's Middle Rouge Interceptor Relief project. The drawings cover the sewer infrastructure route from Telegraph Road to Inkster Road, and from Ford Road to Merriman Road, spanning multiple segments with detailed topographical and engineering specifications. The drawings are marked "For Reference Only, Datum is Shifted" and include plan and profile views of the proposed sewer interceptor relief system, showing existing terrain, golf course boundaries, and the Middle Rouge River.

The historical drawings provide technical reference information for a complex wastewater infrastructure project, featuring multiple alignment options (such as Alternate-B) and detailed elevation profiles ranging from approximately 590 to 675 feet. The documents include specifications for 24-inch diameter pipes with varying grades, multiple trench sections, and engineering notes about construction methods, right-of-way considerations, and geometric alignments. The drawings are part of the documentation for the North Huron Valley-Rouge Valley Wastewater Control System project, suggesting a significant municipal infrastructure improvement initiative involving precise engineering and environmental considerations along the specified road corridors in Wayne County, Michigan.
