BETTER EXPLAINING THE MAP FROM LAST FRIDAY



I included a picture of my large 2 1/2 foot by nearly 3 foot map in last Friday's posting about the Stroh Drain, Ditch, and Berm (SDDB). This map originally produced by me in October 2014 is a very detailed map of Uniroyal/Lanxess's property on the east side of the Canagagigue Creek primarily. One can see four of the ponds on the west (left) side of the Creek namely RPW 5,6,7, & 8. RPW stands for retention pond west. On the east (right) side one can see from the top right corner and downwards (south) part of IR-2, then all of RPE-1,2,3,4,5 . IR-2 stands for Iron oxides 2 and RPE stands for Retention Pit East.

Anything outlined in red represents higher elevation ground and lines in blue represent the lowest ground elevation and hence include the Canagagigue Creek and the smaller Stroh Drain (SDDB) in the bottom right hand corner (i.e. south-east)

On the top left corner of the map there are both photographs of the Stroh Drain taken in 2014 as well as topographical maps of the entire site. The topographical maps are produced by the Ontario Ministry of Environment as well as the Grand River Conservation Authority (GRCA). The bottom half of my map is actually taken from a Conestoga Rovers (CRA) May 2013 report regarding GP-1 & 2 (gravel pits 1 & 2) and is titled "Existing Conditions". CRA helpfully included topographical contour lines and unhelpfully left a few short gaps in the contour lines as they crossed the property line between Chemtura/Lanxess and the Stroh farm. In conjunction with multiple other sources these ground contour lines are quite clear and abvious.

One recent addition to my map is not as yet on this computer image and that is the new red line representing the "Berm" in SDDB. The "Berm" is on the immediate east (right) side of the most northern end of the Stroh Drain and may extend close to 165 to 200 metres. I have previously described here in the Elmira Advocate as it likely being so positioned in order to prevent Canagagigue floodwaters from more readily eroding heavily contaminated soils in the very low lying area immediately east of the Stroh Drain that have been deposited via overland gravity flow from RPE 1-5. The flooding creek to the west breaches its channel and flows south-eastwards across the entire south-east corner except for the high diagonal (north-west to south-east) ridge of land outlined in red on the map.

While the ground contour lines on the computer image are not clear they are very clear on my actual map and their direction of ground surface flow is obvious to any honest, unbiased parties. Of course those parties are in very short supply in Elmira, Ontario, Woolwich Township.

P.S. Also likely not visible on the computer image map is the names of the property owners to the immediate south ( i.e. below) namely Martin and to the east (right) of course is Stroh.




This above map shows the 100 year floodline in yellow. Note the long narrow "finger" hanging down on the right side near the Stroh Drain. This represents the high ground produced by the Berm consisting of the soil excavated from the Stroh Drain.
