Table 6 Palacios Breakwaters Palaclos Harbor, Texas Date(3) 1966 Construction and Rehabilitation History 1970 1983 Two rubble-mound breakwaters were constructed to lengths of 1,700 and 330 ft on the east and west sides, respectively, of the Palacios channel entrance (Figures 6 and 8). The purpose of the structures was to reduce wave energy entering the harbor and shoaling in the harbor slips and entrance channel. The breakwaters were constructed with a core and 2-ft-thick bedding layer of 0,5-in. to 200-lb stone. The core stone was placed to an elevation of +2 ft mlt, a width of 12 ft, and side slopes of 1V:3H and 1V:2H on the outer 700 ft of the east and remaining breakwater sections, respectively. A single layer of 2- to M-ton cover stone was used on the break- waters, with the exception of the outer 590 ft of the east breakwater which was covered with 4- to 6-ton stone. Some toe protection was provided by placing one to two cover stones at the base of the side slopes and extending the bedding layer 5 ft beyond the cover stone. The shoreline, made up of clay banks, was eroding in the general vicinity of the west breakwater. Rubble stone was placed along the shoreline on either side of the breakwater. (No details are available.) The breakwaters were inspected and considered to be in good OF BREAKWATER 1 OF BREAKWATER TYPICAL SECTION SHORE TO STA lOtOO EAST BREAKWATER SHORE TO STA 3»30 WEST BREAKWATER TRES PALACIOS BAY COVER STONE 2-4 T0» TO STA 11*10 6 TON TO STA 17*00 SCALE IN FEET Figure 8.
