How to Monetize his Vacant City Lot?

[Larry Tanner]

I was hoping some sharp minds here could give me some ideas in my situation.

I own a vacant city lot in my city, it's right across the alley from my home.  I inherited it over 20 years ago and it's basically a liability more than anything (meaning, it costs me money with no prospect of making me money).  Taxes are cheap (less than $100 a year) but I have to spend time with upkeep.

Here are the details of the land and what I have looked into to monetize it (and failed), with a diagram in case that helps.

Land details:

• Zoned Residential
• Situated next to (but below) the busiest road in my city.
• About 8,000 sq ft (with about 1/5th being an embankment)
• Irregular shape/contour
• No utilities at this time.

Monetization I have looked into (and failed)...

• Build a small home on it and rent it. 
  NOT ALLOWED. City will not allow development of a home on the lot.
• Rent space to billboard company - Called 2 billboard companies
  NOT ALLOWED - city does not allow any new billboards to be erected inside the city limits.
• Build multi-bay garage and rent each bay out for car storage
  NOT ALLOWED - local law prohibits erecting of secondary structures without a primary structure.
• Rent to seasonal businesses like flower tents, local farmer, etc. Land is not 100% ideal for this (you will see in the diagram, it sit below the major artery road) but any rent would be worth considering.
  NOT ALLOWED - property not zoned commercial.

If any of you have any suggestions on how to monetize such a property, I'd love to hear them.  I'm fresh out of any ideas at this point.

Here's a diagram of the lot in case that helps...
