Be sure to read the article in the October Property Owners Association bulletin. (page 12) It explains in detail the developer has been "mistakenly" overcharging some residents who elected to pay off their infrastructure bonds. In the cited example the resident was charged almost $1,400 when the charge should have been just over $700.
As a result of this residents diligence, the District procedures were changed to protect "future" payments. For the hundreds of those overcharged in the past, there is apparently no concern.
Sounds like a great class action lawsuit!
