Air quality measures improve the environment and reduce the brown cloud. Some air quality measures we have implemented are:
- Implementation and the use of GIS technology to develop routing plans and combining trips to reduce routine maintenance vehicle miles traveled.
- Installation of magnetic locks on park restroom facility doors to reduce staff trips to lock and unlock doors.
- Installation of software to remotely control District computers to reduce trips to facility locations.
Annual tree and shrub plantings in the parks and along the trails to help cleanse the air by intercepting airborne particles, reducing heat, and absorbing such pollutants as carbon monoxide, sulfur dioxide, and nitrogen dioxide. Trees remove this air pollution by lowering air temperature, through respiration, and by retaining particulates.
