Slow Streets- Additional Locations. In case you haven’t noticed the signs on Westpark,Hesby, Beck, Irvine, Otsego and multiple other streets in and around the Valley Village Park neighborhood, we have been identified as a “slow street”.
“Slow Streets” are neighborhood streets where traffic is temporarily calmed and limited to local traffic only to allow people to safely utilize the streets for biking, exercising, and play.
