The following is an example of a current Maryland project in which the Maryland State Highway Administration (SHA) had to balance impacts between natural resources and Section 4(f) cultural resources. Regulatory agencies required the SHA to develop project alternatives that minimize impacts to a local stream and its floodplain, and to two Section 4(f) cultural resources on either side of the existing alignment. OVERVIEW The Arcadia property consists of an archeologically distinct 45-room
Georgian mansion and several outbuildings overlooking the Monocacy Battlefield
of the Civil War. Wounded soldiers from the Confederate Army were taken
to Arcadia during the battle. The property is listed on the National
Register of Historic Places (NRHP). The Markell property is a farmstead
consisting of a neoclassically
Research has yet to conclusively link the Markell Farmstead property with specific Civil War activity beyond the movement of troops across the property. The property is eligible for listing on the NRHP for its architecture and structural integrity. PURPOSE & NEED CHALLENGE
While this alternative would completely avoid both of the historic sites, it presents several problems, including the need for a new creek crossing in the same location as the existing crossing, and the use of several Frederick County roads that could serve as detour routes during construction. The detour would be approximately three miles and require costly interim improvements to the Frederick County roads, including an upgrade of the local roadway network to accommodate the additional traffic from MD 85. Other concerns were raised regarding heavy trucks that travel to the commercial distribution facilities along MD 85. With the closing of the Ballenger Creek crossing, these vehicles would be forced to use the local roadway network, which was not designed to handle a large volume of heavy trucks. Moreover, many of these roads traverse residential areas and could therefore pose additional safety concerns. In addition to the various issues regarding construction, traffic volume and safety, the Section 4(f) Avoidance option presented serious environmental concerns among the Federal Highway Administration (FHWA), the U.S. Army Corps of Engineers (USACE), the Maryland Department of Natural Resources (DNR), and the Maryland Department of the Environment (MDE). Specifically, agency officials raised questions about the level of impacts to Ballenger Creek and its floodplain. While everyone agreed that there is no practical way to avoid stream and floodplain impacts entirely, there was a general consensus that impacts resulting from this option would be substantial. In response to these concerns, the SHA developed two more optionsa stream minimization alternative, which focuses on minimizing impacts to Ballenger Creek and its floodplain, and a balancing alternative, which focuses on minimizing impacts to the two historic sites, as well as the creek and its floodplain.
