The City of Redlands must lower its water consumption by 20% by the year 2020 or risk losing state water grants. To tackle this problem, Redlands wants a better understanding of how residential water is currently being consumed. Income, population density, and vegetation were explored as possible indicators of water consumption.
Required layers: Imagery and census data
The imagery was used to create a vegetation index, which defined a range of high to low vegetation. Census data was used to collect income and population density information.
Once all of the data were processed, a correlation analysis was used to identify which of these three factors was the best indicator for water consumption.
Population density and household income were good indicators of water consumption , however, vegetation was a significantly better indicator. The vegetation may be a good indicator because Redlands is a part of the chaparral eco-region, which is known for dry climate.
With this information, Redlands can now target areas with the highest vegetation and highest water consumption to help lower their total consumption.
