I feel like im seeing conflicting or vague stuff about the signage for this credit. We are going after the option for SSc4.3 in which electric charging stations are provided for 3% of parking capacity. so do the signs that go in front of these spaces still use the same words: "low-emission/fuel efficient vehicle parking only" or does it need to say something like "electric car charging parking only"? (so that hybrids don't park in a charging station)? or are these all the same thing? I wish under each option they told you EXACTLY what wording to use but in the absence of that im just not positive. please help! thanks
