A quantification of the total area of the realigned Broadway Drain is calculated from the top of slope to the top of slope, as well as the HWL of the Detroit River. These calculations have been provided in square meters and can be found in Table 5.

Table 5: Proposed Habitat in Broadway Drain

TOTAL HABITAT AREA OF REALIGNEDDRAIN EXCLUDING CULVERTS &SHEETPILE WALLS	TOTAL HABITAT AREA OF REALIGNEDDRAIN INCLUDING CULVERTS &SHEETPILE WALLS	TOTAL AREA OF WATER WITIN REALIGNED DRAIN AT HWLOF DETROIT RIVER
11,675 sq.m	12,300 sq.m	6,350 sq.m

A quantification of the total habitat lost versus habitat created has been calculated for the top of slop to top of slope and at the HWL. These calculations can be observed in Table 6.

A quantification of the indirect habitat lost in the Healy Drain and the Drainage Channel along the former Water Street is shown in Table 8. It is important to note that these areas were calculated using conservative estimates through site photos and air photo interpretation.
