How to best organize multiple taxonomies when the content resides on categories?

I'm working on a website about public health that has a somewhat confusing data structure. It currently opens up to a list of location categories (one-to-many) that contain a content page and a list of "hotspot types" (also one-to-many), and each hotspot type contains a short content page and a link to a map with locations of that type.

For instance:

• Healthy Eating (category)
  • Community Gardens (hotspot type)
    • Map links
  • Farmer's Markets
    • Map links
• Active Living
• ...

Additionally, there's also a second taxonomy, location types (many-to-many) that basically applies to every hotspot type and is also a content page. Examples of those are "Where we live", "Where we work", "Where we play", etc.

Now, my client requested that we focus the website on this second taxonomy, showing the list of all 6 possible variations on the landing page. This taxonomy should be emphasized, but the categories should still be present somewhere.

My problem here is that while this type of structure is not totally uncommon as categories and tags for blog posts are pretty similar, on that case, the final post is the focus and the page where all the "final content" really resides. On my case, the most crucial content resides on the pages describing each taxonomy, while the last element of the structure is just a mark on the map. I'm finding this structure pretty confusing, but maybe I'm missing something.

Does anyone have suggestions on how to structure this type of information so that the relationship between the elements is clear to the user while retaining the content emphasis requested by the client?

The current website is live, you can find it on http://www.cookcountypublichealth.org/healthy-hotspot. The list of categories is down the page, while the second taxonomy, location types, can be found under Places that Can Affect Your Health on the sidebar.
