On the map

• When opening the page, you will see on the map, engine polygons that are colored based on fire risk, overlaid by hydrant points. You are free to use the "Map Views" dropdown to select which feature(s) you would like to see.
• Toggling the "Hydrant opacity" and "Engine opacity" sliders can adjust the transparency level of hydrant points and fire engines appearance on the map.
• Clicking on each hydrant point or each engine polygon will show a popup window that displays its basic information. However, since there are over 25000 hydrant points with a high density shown on the map, if you would like to check information for individual hydrants, it will be better for you to turn off the engine layer first by clicking the "Map Views" dropdown and de-select "engines".

On the sidebar: Customize hydrant inspection prioritization and views

• If you want to build hydrant inspection prioritization, in "Factors to prioritize", you need to check at least one of the four factors; you are also free to check two or three or all factors with any combinations.

• Please select "Update map" after making your selection to view the hydrant priorities based on your customization distributed across the City. The priorities are score from 1 to 10, 1 is the top priority and 10 is the lowest priority. If you want to only view hydrants of a specific priority, you need to check "Filter by priority?" and toggle the slider to choose the priority value you would like to see. Finally, click again on"Update map" to see the results on the map.
• If you want to view a specifc engine to see how its hydrant priorities look like, after you make selections in "Factors to prioritize", you can choose to skip "Filter by priority" and simply check "Filter by engine?".
