GORST PLANNED ACTION EIS | AFFECTED ENVIRONMENT, SIGNIFICANT IMPACTS, AND MITIGATION MEASURESTable 3.10-4Archaeologically Sensitive Landforms Likely Present in the Study AreaLandform Age Accessibility ResourcesSalt marsh Holocene Inundated for short periods duringthe day.Tide flat Holocene Inundated for long periods duringthe day.Fish, waterfowl, plants, terrestrialmammals.Fish, shellfish.Subtidal coastal Holocene Permanently inundated. Fish, aquatic plants.Berm Holocene Seasonally inundated. Tool stone, grasses.Intertidal beach Holocene Inundated for long periods duringthe day.Fish, shellfish, tool stone, aquatic plants.Upland plain Pleistocene Permanently accessible. Terrestrial mammals and plants, tool stone,ochre.Nearshorelacustrine/marshHolocene Seasonally accessible. Waterfowl, fish, plants, terrestrialmammals.Several specific activities are likely to have occurred in the Study Area given expectations about human behaviorand landforms and their attributes (e.g., stability and accessibility) discussed above. The precontact property typespresented in this section are modeled after types, developed by Lewarch and Larson (2003:6-1–6 11), that focus oncharacterizing the activities represented by an archaeological assemblage (e.g., fishing and fish capture location).The precontact property types that may be present within the Study Area are as follows:• Fish Capture and Processing• Shellfish Processing• Lithic Procurement and Processing• Plant Collection and Processing• Terrestrial Mammal Hunting and Butchering• Habitation• Multiple Processing ActivitiesHistoric Built Environment ResourcesSeveral historic built environment resources have been identified within the Study Area; however a completeinventory of buildings and structures older than 50 years has not been completed. The Study Area contains thelocation of domestic, industrial, recreation, or other activities that have the potential to contain buildings andstructures older than 50 years. A review of the land use history and historical development reveals that theresidential, commercial, and industrial areas were established within the Study Area and that there is highpotential for buildings and structures older than 50 years to be currently located within the Study Area.ImpactsImpacts Common to All AlternativesWatershedImpacts that can adversely affect important cultural resources include anything that might significantly destroy oralter the important features of a cultural resource. Direct and indirect effects to cultural resources can result fromhuman activities or natural events. Under all alternatives, development would occur throughout the Gorstwatershed, to varying degrees as allowed by zoning and applicable regulations.
