The purpose of this map is to show areas that are 600 ft away or less from fire hydrants. This is a conservative number; some fire departments are able to reach structures that are further away from hydrants. The areas within 600 ft are depicted by circle polygons that are colored according to the fire hydrant's water flow rate. A higher flow rate is better, because it means that firefighters can access a greater volume of water in a given timeframe. Uncovered areas may require a tanker shuttle, when tanker trucks are used to haul water from the nearest source to the scene.
This is an interactive map, so please toggle around. The upper-left corner provides buttons to zoom in (+) and out (-). The magnifying glass lets you search for any address of your choosing and will zoom in to that location. The upper-right corner lets you toggle the different data layers on and off. By checking the box, you can toggle the layer on and by unchecking the box you can toggle the layer off. The bottom-right corner provides a legend for the different hydrant flow rates.
