When the LPC permits concrete to replace damaged stone in historic districts, they typically mandate a custom scoring pattern to maintain the classic visual layout. Contractors must tool or saw-cut these joints to specific depths and grid patterns (such as traditional 5-foot by 5-foot squares) to match neighboring properties. Proper decorative scoring not only satisfies landmark design rules but also creates neat control joints that dictate where the concrete will crack as it cures, extending the pavement's life.
