In a rapidly growing desert metropolis such as Phoenix, the question of which water conservation measures and factors actually save water and which do not is an obviously important one. The water-related decisions made today and in the years to come will have lasting impact on the future of this area, including upon its sustainability. Estimates from the City of Phoenix suggest that, in non-SRP-areas, water demand will exceed water supply by the year 2025--absent droughts or intervention.

This report documents and analyzes the results of a multivariate regression analysis designed to estimate the effects on residential, single-family water consumption of a host of factors, particularly water conservation policies.

The study reported here was designed to examine the impact of background meteorological conditions on the propagation of noise from urban freeways in the Phoenix area. The aim was to understand and predict how sound waves emanating from highways respond to the vertical profiles of atmospheric temperature gradients and velocity shear, so that sound measurements can be interpreted with regard to the environmental variability.
