If my memory serves it had to do with outdoor "amplified sound" and the developer was asking for a variance (? I might have the word wrong - basically it was one in a list of things they wanted approval for that was different from the Traditional Neighborhood Development code - the future use code of the parcel). The developer wanted to have sound/noise approval extend for use on a "case by case" basis, but as a planning member said - that is so vague it could include 365 days of case-by-case events involving outdoor noise/amplified sound. The developer clarified that was not the intent (the engineer referenced live music during an art show as an example of intent) and he/they would be willing for that request to be modified so it was agreed that the language would be changed before it was voted on. I think it was left that it would comply with whatever the normal sound ordinance is per the county. Definitely the "case by case" language was removed.
Unrelated to sound...
The variances related to density (or "intensity" as one member corrected) were being asked because the size of the parcel (3ish acres). If that was the only reason, I'm surprised that the adjacent parcel (also zoned TND) was not purchased recently as it was for sale last month. Obviously the architectural plans for the main parcel have already been completed so it would have complicated matters, but it could have given more land to the project so the density/intensity may not have needed as much (requested) modification from the code.
Minutes are not posted, but a video from the proceedings is on the county website, on the line marked 8/13/15, this project was toward the end of the night's agenda:
