From a Holly Street neighbor:

After contacting the police about so many vehicles running the stop sign at Oregon Hill Parkway and Pine St, they sent out an engineer to look at it. They got back to me today with a summary:
The RPD traffic division has contacted the Department of Public Works regarding the traffic issues you brought to our attention. Together, they have devised the following plan of action:
– Oregon Hill Pkwy and Pine St
o DPW plans to place a stop bar and improve the placement of the stop sign.
– Holly and Pine
o DPW will place a stop ahead sign and replace the stop sign for the eastbound movement
