The best source to reference is the local code enforcement officials. Parking lot lighting requirements vary greatly between jurisdictions. Lots of rural areas may not have any parking lot min. light level requirements. Others may have a dark sky ordinance / limit how much backlight/uplight/glare (BUG ratings) you can have. If you're not already, recommend having the site lighting calc'd to also make sure you're not bleeding light into adjacent properties or roadways - asking for a lawsuit from an annoyed neighbor, or someone that gets in an accident because their visibility was limited due to glare.
Another thing to watch out for is height limitations the AHJ will allow for the poles (although with LV 40W fixtures I'm guessing you're doing building mounted lighting?).
Last thing I'll mention, which isn't REALLY related to your original post, is to make sure your pole locations will be OK with the utilities and transportation services near your project - primarily the electric company and the railroad company (if applicable). I've been burned a couple of times for encroaching on their easements.
