Proposition <br />68 authorized the Urban Flood Protection (UFP) grant program, which seeks to fund multi- <br />benefit projects that address flooding in urban areas. <br />The City experiences significant flooding during intense rain events, particularly in the <br />Downtown area. Minimal slope and an undersized stormdrain system combine to facilitate <br />routinely flooded areas, which can have a negative impact on the health and safety of <br />Santa Ana residents, affect businesses, and cause property damage. The projected <br />increase in high-intensity storms caused by climate change will exacerbate these issues <br />and staff is actively working to identify impactful projects to help reduce flooding in the <br />City. <br />One such project is the Downtown Flood Reduction and Stormwater Infiltration Project. <br />This multi-benefit project takes a two-pronged approach at reducing flooding Downtown <br />via the reconstruction and upgrade of the stormdrain infrastructure along Third Street and <br />the construction of a subsurface infiltration system that will capture and infiltrate
