This is a Project Design document and competitive sealed bid solicitation prepared by the Lancaster County Conservation District for the Supplee Farm Restoration Project, a natural channel stream restoration initiative located on approximately 3,500 linear feet of Conowingo Creek in Fulton Township, Lancaster County, Pennsylvania. The project encompasses comprehensive stream restoration services including installation of in-stream habitat structures (toe logs, root wads, brush mattresses, mudsills, single log vanes, rock cross vanes, riffles, and random boulder clusters), riparian bank stabilization with rock toe placement and geotextile materials, bankfull bench grading, one permanent rock-bottom stream crossing and one temporary crossing, streambank fencing, a 35-foot average width riparian buffer, final grading, and vegetative stabilization using specified seed mixes. The design was completed in 2023 by G. Chamberlain and identifies two wetland sites and vernal pools within the project area. A mandatory pre-bid site showing is scheduled for January 20, 2026 at 1:00 PM EST, with bid submission deadline of 12:00 AM EST on February 7, 2026 via the PennBid online platform. The public bid opening occurs on February 9, 2026 at 10:00 AM EST, with anticipated bid award on March 10, 2026 at 10:00 AM EST.
