Palacios Breakwaters 
Palacios Harbor, Texas 
Date(s) Construction and Rehabilitation History 
1966 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 200-1b 
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 4-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. 
1970 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.) 
1983 The breakwaters were inspected and considered to be in good condition.
