beach

A beach is a field of sand or fine gravel adjacent to a body of water. It is listed as an amenity for a particular property when it belongs to that property and is designated for the recreational use of that property's tenants, customers, or users.

The sandy or fine-gravel area lies beside a body of water and belongs to the property. It is designated for recreation by that property's tenants, customers, or other users.

A nearby public beach is not the property's beach amenity merely because it is convenient to reach. A sundeck provides an outdoor place to relax in the sun without requiring a sandy shore beside water.
