Noise

After contacting Livability Court yesterday, I found out, unfortunately, that the noise ordinance in Charleston is only in effect PRIOR to 7am. It would seem the only solution is to press for a change in the ordinance. So far, Palmetto Commercial Properties, the parking lot owner, has been very willing to relay noise concerns to the maintenance company, Dabney & Sons, LLC; Dabney, however, has not been willing to follow the voluntary 8am guideline I've requested. Any thoughts? Anyone else concerned with noisy leafblowers?
