I can not recommend a lawyer...again, it would violate the rules of this forum (they will not let me personally represent contacts made here nor make referrals) but I can point you herehttp://www.azbar.org/FindaLawyer
As a good resource for AZ lawyers.
Happy to address your additional questions
"To prove the damages, I will use the charges incurred when my water was shutoff ostensibly based on the board adopted water shutoff policy. "
That is great. Get proof...that is, be able to bring in proof to the court about the total. Show records of the exact amount. If you can show you incurred a cost based on the boards violation of A.R.S. 33-1805? That is what you are shooting for.
You want to be able to link the violation of the statute, by the defendant, to financial harm suffered by yourself. If you can do that? Then you have "damages". I mention bringing proof, since you need to prove up your damages...so if you can show invoices or some record to give the exact dollar amount? That is what the court is looking for.
You are using the term perjury... technically that is not accurate. Perjury is a sworn statement, in court, that is a lie. What you are describing, if I read the question correctly, is the defendant is making fall assertions in their pleadings. That is not the same as perjury. I would address it with a response to the court that details the errors or omissions and why you believe they are false. If you can show they are lying? That is very helpful for your position (helps destroy their credibility) but do not overstate your case...in that regard, best not to call it something it is not.
Less is more. Pick the major points they are lying or mistaken over...no need to "get into the weeds" if you can avoid it...if you have them on a few major points that they are lying? That is typically all you need.
