On June 26, 2019, California Governor Newsom signed the Fiscal Year 2019-2020 State Budget into law, allocating $1.75 billion to increase housing production. Twenty-nine percent of these funds—$500 million—are allocated to the Infill Infrastructure Grant Program (IIG), which provides gap funding for infrastructure improvements critical to residential and mixed-use infill development. Infill development provides broad environmental benefits including reducing sprawl, vehicle miles traveled, and greenhouse gas emissions. At the local level, these approaches increase walkability, provide a sense of place, and reduce exposure to hazardous substances and contamination through cleanup of former industrial sites.
