This study estimates the potential economic impact of investment in a cold inspection facility at the Mariposa Port of Entry in Nogales, AZ. The study models estimates of volume and value of fresh produce currently diverted to other ports of entry that could potentially travel through Nogales. Potential increases in trade flows for select perishable produce commodities (asparagus, avocados, blackberries, raspberries, and strawberries) through Nogales are then used to estimate the economic impacts to the Arizona economy. Furthermore, the study presents a benefit-cost analysis for the project based upon modeled increases in trade flows. Revised September 2019.
