November 2004, following voter approval. The City of Coronado has attempted to have a tunnel built from the Coronado bridge to the San Diego Naval Base numerous times, and hired Ledford Enterprises to help with the lobbying process in 2002 and 2006. The city endorsed a proposed study in 2004 to determine possible alternatives to resolve the traffic issues, which included keeping the status quo. On June 8, 2010, Coronado voters decided against Proposition H, which would have advised the city to undergo further investigation into building the tunnel. This concluded ten years of studies and proposals by the city of Coronado to find a way to reduce traffic to the naval station during rush hour. Critics of the proposal did not believe that the tunnel would resolve the traffic issues on the northern part of SR 75 or on SR 282. Following this, the Coronado City Council voted to abolish the Tunnel Commission that had been formed to study the issue. Efforts were underway by Imperial Beach city officials to improve the reputation and economic standing of the Palm Avenue area in the first decade of the 21st century. The area was described by the San Diego Union-Tribune as a "hodgepodge of vacant land and aging apartment buildings and businesses, many in need of a coat of paint" in 2003. Residents hoped to revitalize the area, providing commerce right next to an entrance to the beach. City officials offered local business owners loans for necessary construction or rehabilitation in 2005. The Imperial Beach city council approved the redevelopment of the Palm Avenue corridor in 2008, following a study in 2003. A Palm Avenue Commercial Corridor Master Plan was endorsed in February 2009, in efforts to improve the commercial area. In September 2012, the Imperial Beach city council raised objections over the Caltrans decision to increase the speed limit on SR 75 to from on the portion of the highway from Delaware Street to the western Imperial Beach city limit due to concerns about safety. The rest of the highway was to retain the speed limit.
