Assuming a building footprint of up to 5000 sq ft, use could not support the need for a lot of parking (probably <20 spaces).Not interested in auto maintenance and other uses that require disposal (and potential runoff/dumping) of large volume of hazardous materials.Long term, I'd prefer something that contributes to the improvement of this area (e.g. a used car lot might be OK for a couple of years just to generate income, but I'd want to find something more beneficial after that).

I'd be more than happy to discuss any issues with anyone at any time.

You've got your hands full over there and I'd love to connect!

If so, I'd love to chat.
