Based on the predicted noise impacts, additional façade treatments are required for road traffic
noise. Refer to Section 9 for construction recommendations.

An assessment of the worst affected ground level private recreation areas was conducted with the
results presented in Table 11.

                         Table 11: Ground Level Private Recreation Areas – SDAP Criteria
                                                                        Complies SDAP
                                                  Predicted dB(A)
                              Location                                 Criteria 60dB(A)
                                                      LA10(18hr)
                                                                        LA10(18hr) yes/no
                             Lots 52-74                ≤60                    Yes
                             Lots 47-51                ≤60                    Yes


On the condition the barrier recommendations in Section 9.1 are implemented, compliance is
predicted for ground level private recreation areas.
