ALTO Access  Requests

This map logs locations that have received ALTO requests for access to collect environmental data on properties, either as a 'door knocker' or an express post mail legal 'Permission to Access' document.  ALTO has confirmed that participation is voluntary at this point.

Locations are manually pinned by volunteers based on addresses, coordinates or intersections provided. Our goal is to try to provide information to those who are affected.

Please contact us if you have received this notice so we can add to this map. Please contact us if you believe we have made an error.
