Turn restrictive signage was installed prior to 2000 to address resident-shared concerns about perceived excessive traffic volume or cut-through traffic on neighborhood streets. In 2000, the Neighborhood Traffic Calming (NTC) program prohibited such restrictive measures as a method of traffic calming.
In 2011, the County Board adopted a policy to “maintain and enhance a grid-style street network” in the Streets Elements of the County’s Master Transportation Plan. In support of this policy, County transportation staff no longer recommending street closures, restricting traffic flow to one-way, or implementing turn restrictions with the intent of lowering traffic volumes on specific streets.
In 2013, the NTC program transformed into the Neighborhood Complete Streets (NCS) program to ensure that streets are designed for all users of the roadway network.
