East Side Road Closures

"Members and Tenants. We are getting to a portion of the park where complete and lengthy road closures are unavoidable due to there being no room for a pass thru lane for vehicle access, and we cannot have the contractor doing double work to allow vehicles to pass thru at their convenience. Upon notification here is how the road closures will work for the rest of the east side or as necessary. 

The road will be open from Midnight to 8.30 am (will be changed around tide changes), 12 to 12:30 pm and again from 5 to 5.30 pm. If you will need to get to or from your lot during other times of the day it may be necessary for you to park on the west side parking, or near the mailboxes. Although the road may be open sporadically during the day the contractor due to the diameter of the road will not be able to guarantee thru traffic at any other times of the day. The times may be adjusted daily do to tide levels and scheduling conflicts, and we will do our best to give ample notice, but cannot guarantee that more than a few hours’ notice can be given due to the conditions on the ground changing all the time.  We apologize for any inconvenience it may cause and will try and minimize it as much as possible. The east side road closures should not last more than four weeks depending on weather and other unanticipated issues.

If you need rides to your vehicle or from your lot during Key by the Sea business hours please call the office and we will try if available to pick you up via Golf cart and get you as close to your destination as possible.

Sincerely Management
