Sometimes a picture makes a point more succinctly than several paragraphs of text, or several minutes of speech. Last night the City Council was discussing a proposed bond issue to replace our public safety radio system and to spread our existing fire & rescue resources out to four new stations in better locations. I was trying to inform the city council of the benefit or relocating the fire & rescue resources. Essentially, the bigger footprint reduces the number of address outside our reach in four minutes by 66%.
Pink polygons are the current four minute travel time coverage, and the new coverage area after we move to the four new locations. Dark gray background is the current city limits. Yellow dots are the 9,783 addresses inside the city, but more than four minutes from a station. This is a nice use for an animated .gif, even though the argument failed to carry the day.
