This topic is for posting the response from the District Growth Management Coordinator for the United States Postal Service Suncoast District.
As I have previously stated, the USPS has made centralized mail delivery the standard for all new communities and for all new phases of an existing community. The only way a new phase would continue with curbside service is if the new construction continues less than a block from the existing construction.
Unfortunately Capri Isles is more than a block from any existing properties and so it falls under the centralized mail category.
