(OP)
I am trying to find the formula to convert lumens at the street light to effective lumins at the street at varying distances from the light standard. Also, does anyone have any common sense standards for spacing of street lights within a subdivision?

If their not on the NYSERDA website, try the lighting institute at www.RPI.edu. They are the authors of the reports.

Lighting manufacturer's will usually furnish you with design calculations for your layout or help you develop a pattern. With so many variables, there's no quick and easy formula.
