Tudor Wharf Draft Environmental Impact Report EOEA # 6744 



typically deposited as the result of 

 tidal action or in marsh areas along the 

 shore line of a slowly rising sea. This 

 organic soil strata ranged up to 14 ft. 

 in thickness where encountered with the 

 top of the strata noted from E. 4.5 to 

 El. 14.5 (BCB). 



Miscellaneous Fill A man-made layer of 

 fill was placed across the site to the 

 present grade. This fill layer consists 

 primarily of an unsorted mixture of 

 medium to fine sand, silt and clay with 

 varying amounts of cinders, brick and 

 cobblestone and was found to vary from 

 approximately 4.5 to 18.5 ft thickness. 



Groundwater Conditions Groundwater levels 

 noted in the available subsurface data 

 indicate groundwater levels ranging from 

 El. 3.8 to El 8.5 (BCB). Note that due to 

 the granular nature of the miscellaneous 

 fill soils and the close proximity to 

 Boston Harbor, groundwater levels are 

 anticipated to reflect changing tide 

 levels.
