Subsidence and erosion caused by waves <br />induced by the navigation channel have caused the loss of a historic beach. <br />Several years ago, the beach was popular and w~ a recreational park for the <br />public. After the creation of the Intra Coastal Waterway Navigation Channel the <br />waves created by ships induced strong erosion and the beach was lost in a few <br />years. Although the shoreline is in some areas protected by rip-rap and a bulkhead, <br />the erosion caused by water surges caused by ship wakes still deteriorating the . <br />shoreline. ' <br /> <br />Presumed Causes (if avallable): <br />Water surges caused by ship wakes are one of the strongest causes of <br />erosion and deterioration of this historic beach. Other presumed cause of the <br />problem is subsidence. The Harris County Coastal Subsidence District estimates <br />that the area has subsided 6-7 feet since 1906. Although subsidence has been <br />minimized in the last 25 years, past subsidence increased the affect of erosion. <br /> <br />1 <br />
