For example, a location with a value of 15% is expected to experience an increase in the total precipitation of the 25-year storm of 15%. Extreme precipitation is an indicator of flooding that can affect infrastructure and operations. Darker shaded areas represent an increase in precipitation and lighter areas are a decrease. Values shown are the median of multiple climate model projections. </SPAN><SPAN STYLE="font-weight:bold;">Potential Impacts ··· </SPAN><SPAN>Agriculture and Food Systems: Heavier precipitation is expected to intensify flooding and inundation of agricultural lands, which can delay spring planting, affect crop quality and quantity, increase erosion and runoff, and increase susceptibility to root diseases. Economic Development: Heavier precipitation is expected to intensify flooding in low-lying areas and require higher capacity storm water drainage systems. Transportation: Heavier precipitation events are expected to intensify flooding, landslides, and erosion, which can interrupt transportation routes, damage infrastructure, and increase maintenance and repair costs. Zoning: Heavier precipitation events are expected to intensify urban flooding and demands on storm water systems, which can affect zoning restrictions on new buildings, and require revised building codes for development in more frequently flooded areas.</SPAN></P></DIV></DIV></DIV> Raymond, C., M.
