CAUTION - SUBMARINE PIPLINES AND CABLES
Additional uncharted submarine pipelines and
submarine cables may exist within the area of
this chart. Not all submarine pipelines and sub-
marine cables are required to be buried, and
those that were originally buried may have
become exposed. Mariners should use extreme
caution when operating vessels in depths of 
water comparable to their draft in areas where
pipelines and cables may exist, and when
anchoring, dragging or trawling.
Covered wells may be marked by lighted or
unlighted buoys.

NOTE D
The City of Richmond is requesting vessels use extreme caution when turning or anchoring in the vicinity 
of their 72" diameter sewer pipeline which is located 9300 feet offshore of Point Richmond at a depth 
of 26 feet below mean lower low water in approximate position 37°54'47"N, 122°'25'06"W.
