Locate (through records or research) and interview participants in the market IE; investigate.  

The California Department of Justice, in conjunction with the California Department of Housing and Community Development, is investigating the charging of School Impact fees.

I like the Series approach, but not all states offer the entity, if yours does, investigate the option.I'm in awe of the stupidity here suggesting convoluted BS right after an attorney just addressed the issues, it's as if what he mentioned didn't even sink in and that there was some greater insight as to the ways to out smart reality.
