Geocode blocks/sections of ACT DAs with no addresses

...then geocode back to nearest street name. Is this necessary or is raw lat/lon an acceptable address for PlanningAlerts? 

These blocks tend to be large areas so an alert radius might not capture the single point/address chosen to represent the whole space even if some of the space is in that radius - is there any plans to support polygons? 

There are also still some DAs where the block/section cannot be found (lol.) so NO ADDRESS gets written to the database. Is this okay or should they still be excluded?
