What operating system version of Member Tools are you using? The issue may be a mapping program error or it could be a platform version of Member Tools issue. I notice that the online Ward Directory and Map as well as Android Member Tools use Google Maps. I assume the same would be used for iOS Member Tools, but I am not certain.
Check to see if the same thing happens in the online Ward Directory and Map for those new member households in the new development areas. For those situations where the issue is the same for Member Tools as well as the Ward Directory and Map then it is most likely a Google Maps issue. I have noticed the location of the map point in new development areas to lag as much as a year until Google updates their maps. For those Google Maps issues what I get are two separate 'general' mapping plots. One is the mapped location is in the center of the street, from street end to street end, when Google does not have a house number location. The other is in the center of the zip code if they do not have the street mapped for a new, or unknown, street. I have submitted location updates to Google using geographic coordinates and they generally get corrected within three weeks or so.
I have been able to correct most mapping location errors using the Ward Directory and Map. This can be done even if Google does not know where the address should be. Ask your ward clerk to update, or verify, the address location in the online Ward Directory and Map. He will need to know where the address actually is to move the location plot. This should correct the 'general' mapping error if it is caused by an unknown location by Google.
