Actually, yes I am. No matter what I build in this location will require a building permit. I had to design it to mimic a swimming pool and jacuzzi layout and with minimal digging (only 30 inches). In the event I wanted to sell our home, I will have the flexibility to convert my pond to a pool. Hearing all the horror stories of lessened property values because of a pond, I figured I'll incorporate a design to kill two birds with one stone. The City will see swimming pool, I will see koi pond. The building code requirements are the same.
