Priority, shaded parking for low emission vehicles would boost their use. The recommendations submitted by the Urban Heat Island Reduction Task force are simple as well. Studies indicate that ambient temperatures in city centers can be up to eight degrees higher than those in the surrounding countryside. The group proposes that the Planning Department adopt a series of new policies and change existing ordinances to encourage and mandate major increases in tree canopy. The shade and evaporative cooling from trees lowers urban temperatures, lessening the formation of ozone.
Trees also absorb ozone, nitrogen oxides, and particulate matter.
They also suggest increasing the use of light-colored, heat reflective materials on roof and street surfaces to lower temperatures. The Building Codes Task Force recommends specific uniform guidelines for the eight-county region that would reduce energy consumption. The report looks to today's technology for help, suggesting that city building codes be revised to reflect available high-efficiency lighting, air conditioners, major appliances, and programmable thermostats. The task force even suggests a licensing system for building operators, who would be required to attend classes on energy efficiency. The general recommendations outlined in the reports are similar to those being explored and adopted in many parts of the country today.
