20210817 Pearsons Rd, Arborist Report 2

3. Inspection Results

3.5 Site Map Figure D, Cut & Fill plan, shows the trees within the waterway corridor have a bio
retention basin, cut/fill, a swale drain as well as a footpath/bikeway affecting them.
There are significant changes in the hydrology in this area as well as the diversion of surface
water to the existing creek.
A storm water line and outlet are also shown on the STORMWATER CATCHMENT PLAN
160-001-400, which intersects many of the waterway corridor trees outside of the cut/fill area.
It appears as though a stand of Paperbarks can be retained to the east of the bioretention basin
outside of the swale area.
The remaining allotment has been cleared of vegetation which inturn would put additional stress
on the taller upper canopy species within the waterway corridor. The Swamp Mahoganys would
be the most affected by the exposure. Cut and or fill works within their SRZ (structural Root Zone)
would see these upper-canopy species become a high risk rating classification to the surrounding
residential properties as well as the future proposed properties.
