Remmington Arms and Polaris also just opened plants, and Boeing already had a huge presence there as well as Toyota.  

The water leaking from the cracks will be found by any plants, trees especially.But, even if these problems exist a good roto-rootering will clear them up.  

This is also the location of the world's 2nd largest solar generating plant. 

Recently I've read the news of Boeing laying off several hundred workers at its Everett plant. 

@Carson Plant depends on the state you are in.

I tried to save some money but putting some wood chips, I might have to invest and plant some grass. 

No landscape other than planted grass, no amenity area, no storm utilities (the property sheet drained to a ditch), no appliances, super low end fixtures, no perimeter fence, 8’ ceilings, all siding, no masonry facade and the city gave the property to the developer and waived impact fees.

In California there is a tax break for planting fruit or nut trees on your property, although it may only be for the tax value of the trees.

With all the developments you mentioned and with Denver affordability reaching a ceiling in much of the metro area, Elyrea/Swansea/Globeville is very much in the path of progress, but at the same time the smelting plants and refineries of ASARCO literally poisoned that area to death for many, many decades, making the soil extremely toxic. 

The addition of Supersonic's new aircraft plant in Melbourne should be another boost for the county adding 700 new high paying jobs at the plant alone.
