That's such a long run it may be better to have the power company run a service lateral and use a standard residential 37kw pad transformer. But they may have a maximum limit to the length of the underground wire.
If you have 575 volt then you already need a transformer. A residential over head high voltage to single phase is probably cheaper than an industrial 575 to 240v transformer.
To run 37kw on 4,160v they would only need to run about a 12 gauge feeder wire. So the trench, conduit ect would be small, so less parking lot to fix.
