VICINITY MAP

S ounding and elevations are in feet and refer to the plane of NOS Mean Lower Low W ater (MLLW ). Epoch 1983-2001. T ide correction Based on Geoid 2012A using R eal T ime K inematic (R T K ).

Horizontal Datum: W GS -84. P rojected coordinate system: Lambert Grid P rojection, S tate P lane, W ashington North Z one, 4601, S urveyed in North American Datum of 1983/2011, P lotted in North American Datum of 1983/91.

Horizontal units are U.S . S urvey Feet.

T he information depicted on this map represents the results of surveys made on the date indicated and can only be considered as indicating the general conditions ex isting at that time.

S oundings taken above the datum plane are prefix ed with a (+) sign.

S ounding and elevations are in feet and refer to the plane of NOS Mean Lower Low W ater (MLLW ). Epoch 1983-2001. T ide correction Based on Geoid 2012A using R eal T ime K inematic (R T K ).

Horizontal Datum: W GS -84. P rojected coordinate system: Lambert Grid P rojection, S tate P lane, W ashington North Z one, 4601, S urveyed in North American Datum of 1983/2011, P lotted in North American Datum of 1983/91.

Horizontal units are U.S . S urvey Feet.

T he information depicted on this map represents the results of surveys made on the date indicated and can only be considered as indicating the general conditions ex isting at that time.

S oundings taken above the datum plane are prefix ed with a (+) sign.

T he location of navigation aids are provided by the U.S . Coast Guard or the Corps of Engineers.
