Mainsail Drainage Project

Mariner’s Cove residents may have noticed JULIE posting flags for digging. The drainage project is ready to begin. The project will replace the existing drainage which will improve the flow of storm water and prevent flooding in the area. Construction will most likely begin on Monday, March 30th. Please be aware that the intersection at Mainsail and Windjammer may be blocked. Signs will be posted and if your home if affected, you will receive a notice from the engineering company. We apologize for any inconvenience.
