unbound forwarding local and dnssec proxy

I am uncertain as to how to configure unbound to do the following:
    - forward local domains to a local authoritative server and not cache.
    - forward all other non-local requests to a dnssec proxy and cache the results.

I am having difficulty getting this to work the way I understand the configuration options.

Setup:
OpenBSD 6.2
unbound 1.6.6
nsd 4.1.10
dnscrypt-proxy 1.9.5

unbound.conf
