This is a big week in the historic district – say goodbye to the shed roofs. Whether you liked them or hated them, they will be no more at the end of the week. Once the shed roofs are gone, sidewalks will be ripped out and replaced. Property owners are working with an architect to design new façades – The 600 and 800 block facades will be completed by November 15, while the 700 block facades will be installed in 2011.
