New developments also need police, fire, and ambulance services resulting in more equipment and more personnel to cover the expanding population. New developments mean new children, thus, new schools. These new schools must cover all ages and grade ranges, elementary through high school. Developments mean new roads, road-widening, road lights, traffic lights, and road work equipment. Also, more personnel are required to do all the work.
More people generate more trash.
Landfills will fill-up quicker, and new waste disposal sites will need to be found. As the population gets older, services will have to be provided for the increase in senior citizens. With every new road, lawn, sidewalk, and roof, pollution increases. Street runoff of automotive waste, herbicides, pesticides, fertilizer, and animal waste can affect natural areas next to the development areas. Compacted soils in the development area also increase this runoff.
