areas of potential flooding were indicated within this system by the
OTTSWMM model for the 1 in 2 year to 1 in 100 year storms.
2. Franmor Drive, Chapel Drive, Dainton Drive, Abbey Lane and part of Armour
Road system – this area drains to the same outfall as the previously described
area joining it about 180 m from the river. Table 4.6.2 shows the estimated
depth of flow in the major system for the 1 in 2 year to 1 in 100 year storms.
Drawing SF-2 shows the extent of potential local flooding in this area for the 1
in 100 year storm. As indicated, the depths are such that although the curbs
would overtop and driveways would be partially flooded, no structures would
be impacted. Hence this may be considered to be “nuisance flooding” which
does not require any specific remedial measures to reduce it. Potential options
to address it are, however, discussed in Section 5.3.
