Need a quick way to determine a list of valid topics for an address

[carlyleec]

Right now valid topics are determined based on the data cache (which we are trying to eliminate) such that if there are crime attributes for an address then the crime topic will be shown in the topics list. The same thing goes for development. Likewise, if its in the city then we show the trash and recycling topics. If we have an address or addresses we can show the property topic. If the street is in the street's geocoder then we show the street maintenance topic. You get the idea...all these depend on the data cache layer.

So...

We need a way to come up with a list of valid topics based solely on the latitude and longitude coordinates of an address and the topic's geometry or the geometry of administrative boundary (like city and county limits). We don't currently have any admin boundaries but I can add them to the ArcGIS for Server instance.
