The Quincy Steet Cannery is located at the waters edge on the Pbrt Townsend waterfront
and is constructed directly on top of the southeast-facing bulktiead, imnediately adjacent to
the old.Quincy !.teet lerry Dock. As can b€ seen from the photograph in Figft Zltle
approximate ordin4ry high water na{k is midyvay up the bulkhea4 aia poiniabouiT fert
above the foot of the bulktiead.
The base of the bulkhead is at atidal elevation of approximately + 2.5, (above mean lower
low water = MLLW). The intertidal area imneAateiy adjacent to the bulkheaA'rna
extending seaward from it for l0 to 15 feet is composed of large, broken slabs of concrete.
Seaward ofthese concrete slabs the intertidal subJtate is comlosed of san4 grauetaod o;
the southwest aspect ofthe property, larger cobbles and stones. Alo4g tncsoithwest
boundary qf the Cannerybulkhead is a sandy beach, with a sligbtly clivated rock and gavel
bar extending out into the lower intertidal.

INTERTIDAL BIOTA
the'
Ulva and Enteromorpha in this area is not aftache{ but washes arouud with the dsitg and
falling tide. It appears that the area is not well flushed by longshore curients or tidal action,
as algae, leaves and wood chips are cornmon in this nearshore area.
Three small patches of eelgrass were noted within 30 feet ofthe bulkfiead. Two patches of
the local eelgrass Zostera marina are located on the southeast margn ofthe inJertidal as
shorin on Figure 3. The larg64 denser patch is approximately 6'by 3' in size and is 27'
seaward of the bulkhead. A smaller, spaf,se patch approximately 5' by 2' insize is located
another 4 feet seaward ofthe dense patch. On the sotrthwest portion of the intertidal area"
near the rock rubble bar, a small, sparse patch (approximately I' by 3') of Japanese eelgnss,
Z. iaponiium is present on the sandy bottom.
A variety of invertebrate species typical of the local intertidal fauna was observe4 including
small red rock crabs CCancer antennarius), and several species of starfish and sea cucunbers.
SUM1UARY
The intertidal area in front of the bulkhead at the Quincy Steet Cannery site is primarily a
rocky-shore intertidal fauna and flora. Two species of eelgrass are present in sandy 6reas of
the intertidal at 18' and27'from the bulkfiead wall. The other algal species in the arda are
predominantly tllva aud Enteromorpha- much of which is not attached"
The southeaslem exposure of the site will allowthe intertidal in front ofthe bgtksead tobe
fully expos.d to r, ''iight at all times,of the year, so that there should be no inaAing effects
resultingfromthecantileveredl0-footwidewallcwaypropgsedforthesite. " '.
