Hi there. In this changeset you've edited the boundary of "Unincorporated Colma" to include the admin_level=8 tag. This is inappropriate for an unincorporated area. admin_level=8 are reserved for areas with a town government (e.g., a mayor and city council). This unincorporated area should either be removed entirely or not be tagged as an incorporated town.

Thanks!
