What this means

Residents can expect more stop-sign, speed, and no-parking signage in several areas, including near Reeder and Renshaw, Valley Center Road and Cienega Avenue, Bonita Avenue, and Allen Avenue Elementary. The committee also directed staff to place speed trailers on Baseline Road for two weeks and to keep law enforcement presence in the Shellman Avenue area because of its proximity to a school. Some items were closed with no further action, while others will require follow-up letters or agreements with nearby jurisdictions.
