I am creating a series of maps featuring a certain set of layers (floodplain zone and critical facilities). Each map will zoom in one of our municipalities (there are 62 in total). It's an utterly repetitive process so I am trying to find a way to automate. An example of the map will be like the pictures shown below:

I zoom to the Bethlehem City, export the map

first zoom

Then I zoom to another municipality and export the map.

2ND zoom

There must be a way to automate this. My initial thought was to iterate through feature selections using iterator in ModelBuilder. Then I got stumped on the "Zoom in" and "Export Map" steps. I couldn't even find tools that do these. But I think there shall be ways to do both of these steps through ArcPy. I wish my ArcPy skills were better, but I guess this is the kind of pain that will push me to learn more about Python.

This does not require ArcPy or ModelBuilder, although ArcPy can certainly help if you encounter more complex map series requirements.

What you describe is the use case for Data Driven Pages:

Data Driven Pages allow you to quickly and easily create a series of layout pages from a single map document. A feature layer, or index layer, divides the map into sections based on each index feature in the layer and generates one page per index feature.

In this case your index layer will be your municipalities layer.

Once you have spent a few seconds enabling Data Driven Pages on your map, you can export it to PDF (one municipality per file or a map book of all municipality maps in one file).
