Join your neighbors and local scientists to document the highest tides of the year! Teams will use community science kits to explore how low-lying spots along the waterfront are affected by high tides. Measure flooding and take pictures alongside local experts. San Rafael is one of the Bay Area's most vulnerable cities to sea level rise, and the information you collect will help our community prepare. Waterproof boots recommended! This event is free but please register in advance with Kate.Hagemann@cityofsanrafael.org.
