In response to your questions,

(1) if the ZBA had proper authority to hear this application in light of the ZBA
code, 

The ZBA granted frontage variances, they did not hear an appeal to a PZ decision. So yes they have authority.

(2) if they did have the authority was the decision in keeping
with the code and

If there was a hardship the ZBA could grant the variance. It is up to the ZBA to listen to both sides and decide if there is a legitimate hardship. In this case they decided there was a hardship.

(3) what recourse might be available to dispute the decision. 

Pursuant to state statute, just like IWWA and PZ the recourse is to the Superior Court. No official or other Commission has any oversight over their decisions.

This matter has to go back to PZ for a resubdivision of the lots into 4 lots so there will be another hearing sometime in the future.

As I stated the proposed lots now go back to PZ.,,,a lot in the R-30 zone requires 150 feet of frontage. He got a variance to that requirment, not an appeal of a PZ decision.

As stated its up to the ZBA to determine if a hardship exists or not, so no sense arguing whether they are right or wrong...the decision stands unless overturned by Superior Court.
