The county Historic Preservation Commission is worried about the effects four state highway improvement projects could have on four historic properties.
Sallie Van Rennselaer, chairman of the county commission, sent the commission's concerns to Delegate Rosemary Hatem Bonsack, D-District 34, earlier this month.
"The last delegation made plans with the state roads department,and we were always fighting them after the decision was made," Van Rennselaer said last week.
"We wanted to make this delegation awarewe'd like to be in on the process, so we can work with them."
Van Rennselaer said the Historic Preservation Commission is concerned about the following projects:
* Widening of Route 7 in Abingdon. The commission says the road work would affect property owned by Michael and Jan Stinchcomb that is a Harford County landmark and is being considered for placement on the National Register of Historic Places.
* Building a Churchville bypass that would cross the Paul Harlanfarm, which is listed on the National Register of Historic Places.
* Rerouting Route 155 into Havre de Grace, which would affect Mount Felix and Sion Hill properties. The Maryland Historical Trust holdsan easement on the Mount Felix property. The easement prevents development. Sion Hill is listed on the National Register of Historic Places.
* Reconstruction of the Route 161 bridge over Deer Creek, which could affect Wilson's Mill, a property on which the Maryland Historical Trust holds an easement.
