final CsvMapper csvMapper, final boolean includeHeader, final boolean yankColumnRequired, final boolean includePreferredSiteToggle) {

Boolean parameters are a bad idea.

You could end up with functions like:
public void someFunc(true, true, false, false, true)

where there's no context into what the parameter represents.

It would be better if these booleans could be wrapped in something like a csvOptions object, which has attributes like:

csvOptions.includeHeaders
csvOptions.yankColumnRequired
csvOptions.includePreferredSiteToggle
