Methods improving the gently sloping revetment to enhance coastal use were investigated through field observations along ten coasts in Chiba Prefecture. The shapes of the revetment such as slope and height of step were measured. For use of the gently sloping revetment as steps, the height less than 20cm is preferred, whereas for the use as the chair step, height larger than 20cm is preferred. Uneven surface of the revetment in the longshore direction is not recommended for use. A method attaching a wooden chair to the revetment for the use of the steps is proposed to avoid strong heat conduction from the concrete surface in summer.
