Gun Rock breakwater (Figure
was constructed to a length of
approximately 250 ft.
The Gun Rock breakwater was extended 90 ft seaward, and the 385-ft
Short Point breakwater was constructed. The breakwaters were built
with a 6-ft crown width and
side slopes using 0.5- to 6-ton
stones. The smaller stone sizes were used as core stone. Design
crown elevations were +21 and +24 ft mlw at Gun Rock and Short Point,
respectively. Total cost was ,000 for placing 7,500 tons of stone
(approximate figures).
The breakwaters were inspected and considered to be in good condi-
tion. Because of an adjacent bridge abutment, the Short Point break-
water no longer serves a useful purpose, and no reason for future
maintenance exists.
The Gun Rock breakwater was visually inspected and considered to be
1974
in good condition.
