In 2006, California voters approved Proposition 1B which established $2 billion in potential funding for local streets and roads. These funds are distributed by formula to cities and counties throughout the state. Of this particular Prop 1B funding source, San Diego County has received over $69.3 million.
On October 15, 2009, the County Board of Supervisors adopted a resolution designating up to $41.5 million in Proposition 1B funding for specific local streets and roads projects. This designation was for $31.1 million from fiscal year 2009-10 and $10.4 million from fiscal year 2008-09. The October 2009 resolution was in addition to funds received for fiscal year 2007-08 and superseded prior resolutions that designated Proposition 1B funds. Since that date, the Board has reallocated some Prop 1B funding and on January 25, 2012 approved a new funding plan.
