0.2 seems to be the standard regulation around NH.

I'm used to seeing 0 past the property line which implies shielding the lights.

I've been convinced we should hold the current standard at 1.0. I'm sure the dark sky people will fight it.

Varies by location, but we've got some fierce shielding requirements, max height of light poles, etc. At residential property lines there is also a 0 footcandle restriction.

I always describe our 0.2 footcandles standard as equivalent to "a full moon on a cloudless night". I see no point on deviating from that and the PC seems to agree with me.

Our standard is 1.0 footcandle at a property line of adjacent residential property.

Other question that will reveal, that I've only just begun being the person with the light meter figuring this stuff out, where do you point the meter when taking the measurement? Do you hold it at ground level? Point it at the light source?
