152 Shan ley Street Vision Statement SITE AND CONTEXT Page 01 of 06 amp Existing 4 & 1 Storer The subject property is addressed 152 Shanley Street and is located at the northwesterly Building on the Site corner of Shanley Street and nuke Street West.. The site is 0.35 hectares (4.87 acres) in area and i5 currently occupied by a building which is 4 storeys in height along the [duke Street frontage and a portion of the Shanley Street frontage .and a 1 storey section of the building oriented along the Shanley Street frontage. The 4 storey and 1 storey buildings were constructed independently of one another and were originally used for light industrial purposes most recently by Electrohome and subsequently Art Fite Advertising. There has been limited use and maintenance of the buildings since 1990 when Art Rite Advertising declared bankruptcy. The property is privately -owned, in tax arrears and widely considered to be an "eyesore'" in the neighbourhood. lfnap: Map of subject proper it ]IMPIM The Site Requires The subject property is known to be contaminated and will require remediation with the Environmental objectives of preventing further movement of the contamination off-site and to prevent Rernediation vapour 1ntrusions into existing. and/or future buildings. The type and extent of the known contamination is outJIned in a Ministry of Environment and Climate Change Franz report. The principle source of contamination is TCE, which is a chlorinated solvent (a common degreaser), and is the result of pour disposal practices of waste paints and solvents by Art Rite Advertisingvia a pit that was excavated through floor slab wvthin the northeast part of the 4 storey portion of the building,. Accordingly, ori -site soil contamination is most significant directly beneath the building as well there is contamination of groundwater flows principally in a northeast direction. There are no known impacts of vapour intrusions into nearby homes. Remediation often involves a combination sof removal/disposal and risk assessment measures (measure that contain vapour intrusions). Risk assessment measures are more demanding and expensive for residential development compared to many other uses. However, risk assessment measures are less demanding and expensive if residential development is separated by iron -sensitive uses such as a first floor commercial space or an underground or above ground parking structure. known as 'grade separators'. An underground parking structure would assist greatly in remediating for vapour intrusions, Remediation of this site has a high potential to impact the building's structural integrity, since as noted, the contamination is most significant beneath the existing building, i.e. it would difficult to access without undermining the building. Also, it is very difficult to retrofit an existing building to prevent vapour intrusions. At the present time, the cost of remediation is greater than the value of the property with the existing building and the current pJanning permissions.
