Most older subdivisions have very little restrictions on cutting down trees. If you are in a condo it may be that the association would have rules to govern the removal of trees. I don't know whether you are in a house or a condo, but that subdivision has mostly large lots and the homes were built in the 70's, so it would be my guess that you have no rules. If you are still concerned, don't have an association, you can contact any title company and they can give you a copy of the covenants for that subdivision. It may be that those rules (or covenants) are on your as-built survey, considering the year built.
