The boundaries were created considering the City of Edinburgh Council ward boundaries, the Church of Scotland's parish boundaries and where the existing membership was living.  These boundaries are a guide for the Association on where to base its concerns, but are not to be taken as rigid.  The Association's concerns also include areas outwith these boundaries that may have some impact on Colinton or where appropriate to support like-minded associations (dominantly those for the areas immediately surrounding Colinton).
