Comprehensive Condition Survey and Storm Waves, Circulation, and Sedimentation Study, Dana Point Harbor, California
Abstract
Dana Point Harbor is located in the City of Dana Point, midway between Los Angeles and San Diego, along the southern Orange County Coast of California, as depicted in Figure 1-1. The harbor consists of dual protective breakwaters (East and West Breakwaters), two recreational marina basins, a turning basin, two anchorage basins, a boat launch ramp area, a bathing beach, and several shallow-draft navigation channels. The development of Dana Point Harbor was initiated in 1949 and an optimal design plan was later selected after various design alternatives were formulated and evaluated. Construction of the dual breakwaters at Dana Point Harbor commenced in 1963 and was completed in 1968. The harbor operation for boat occupation and recreational purpose began after the completion of channel and basin dredging in 1970. Table 1-1 presents the physical dimension of the dual protective breakwaters as well as various project depths in the channels and basins. At the time of construction, both the East and West Breakwaters were designed as a semi-permeable structure as comprised of multiple layers of riprap stones without an impermeable core layer. The weight of riprap stones in the outer layers range from 6 tons at the landward end to as heavy as 20 tons in the structure head area. Small voids were left intentionally during stone placement to allow currents partially flowing through the breakwaters, thereby promoting better water circulation within the harbor.
