The Village of Libertyville and the Libertyville Township Road District have initiated a preliminary engineering study for a potential reconstruction of the Rockland Road Bridge over the Des Plaines River in the Village of Libertyville and Libertyville Township.
The proposed improvement includes impacts to the Old School Forest Preserve, a Lake County Forest Preserve District (LCFPD) property. The impacts to this resource have been minimized so that the function of the property will be maintained. The Village of Libertyville and Libertyville Township Road District are seeking public comments on the effects that proposed improvements to the Rockland Road Bridge will have on the Old School Forest Preserve. The Old School Forest Preserve, which is under the jurisdiction of the LCFPD, is a significant, publicly owned forest preserve and recreational area. As such, it is subject to protection under Section 4(f) of the U.S. Department of Transportation Act of 1966. For the Rockland Road Bridge Project, the Village of Libertyville and Libertyville Township Road District intend to seek a Section 4(f) “de minimis” impact finding from the Federal Highway Administration based on determination that the project will not adversely affect the features, attributes, or activities that qualify the Old School Forest Preserve for protection under Section 4(f).
Effects of the Rockland Road Bridge project on the Old School Forest Preserve will include the permanent placement of stone rip rap at the base of the easterly abutment to prevent erosion, permanently re-aligning the path connection between the bridge and the Des Plaines River Trail based on coordination with the LCFPD, and temporarily impacting areas adjacent to the roadway to construct retaining walls and gain access to the bridge structure. Mitigation will include the construction of retaining walls and a narrowed roadway cross section to keep roadway grading slopes from adversely affecting the forest preserve property.
