The contractor mocked up a small section of cobbles so we could get an idea of how the point bar area will look. The area will use cobbles that are approximately 6" in diameter, with coarse sand spread between them for stability. The mock-up shown above used materials on hand rather than the materials we want in the final product, so is has road sub-base instead of sand. This worked well enough, but didn't look very good. Even with the larger sub-base material, the field of cobbles was quite stable. The area will be uneven to maintain a natural look, but will be fairly easy to walk on (though not for those in high heels or toddlers just learning to walk).
