Oro Valley Town Council
Dear Council Members,
I am sending this information regarding the abandoned Vistoso Golf course pond. I am a resident of Oro Valley residing in the Vistoso

I am a retired professional engineer and am providing this information as a resident to assist you with your decision making process.
Calculations are included. If your wish further explanation my contact information is provided.
