OP any "small" miss can set you back on time and dollars. 1. Have an Engineering firm pull together. Many Many issues can come up, that they should identify. Soil compaction, setbacks, zoning, utility access, road access, etc etc. The color of your Fire Hydrant nearest you. Is it private or public? Do you need to spend $100,000 to bring Water or sewer lines to your property? Are you talking a Putt Putt golf course or a 5-story condominium next to a river, etc. More details help. 2.
