Item - 2024.SC13.2

The Scarborough Community Council recommends that:

1. City Council designate the lands municipally known as 1891 Eglinton Avenue East, as a Class 4 Noise Area pursuant to Ministry of Environment Environmental Noise Guideline - Stationary and Transportation Sources - Approval and Planning Publication NPC-300, August 2013, as shown in Attachment 3 to the report (April 17, 2024) from the Director, Community Planning,.

2. City Council direct the Interim Chief Planner and Executive Director, City Planning or their designate to forward a copy of the City Council Decision Document to the Ministry of Environment Conservation and Parks (MECP).

This report recommends that City Council designate a portion of the lands known municipally as 1891 Eglinton Avenue as a Class 4 Noise Area under the NPC-300 noise guidelines administered by the Ministry of Environment, Conservation and Parks (MECP).

City Council accepted a settlement offer for a portion of the subject site which will result in lands at 1891 Eglinton Avenue East being redeveloped with a mixed use proposal consisting of a total of four buildings: three towers, with heights of 48 storeys (Building A), 44 storeys (Building B), 44 storeys (Building C), and one mid-rise building with a height of 12 storeys (Building D). The buildings would comprise a total gross floor area (GFA) of approximately 106,831 square metres of which102,190 square metres is residential gross floor area and 4,641 square metres is non-residential gross floor area. A total of approximately 1,700 residential units are proposed.

A Detailed Noise and Vibration Impact Study was prepared by RWDI to support to the proposed development at 1891 Eglinton Avenue East which concludes that the proposed development site is suitable for a Class 4 designation as defined in the NPC-300 Environmental Noise Guideline. The study was peer-reviewed for the City by RJ Burnside and Associates Limited and they concluded that the Class 4 area designation for the proposed development site is supportable.

Under NPC-300, a Class 4 Area designation allows for higher daytime and night-time sound level limits than would otherwise be permitted in relation to a noise sensitive land use such as residential dwellings and associated outdoor living areas. Any impact of the permitted higher levels would be mitigated by noise control measures that are part of the development of sensitive uses. Similarly, the slight increase in permitted noise levels provide for the continued operation of surrounding employment uses without impact caused by the introduction of residential uses on the subject lands. The Class 4 designation would apply to the identified portion of 1891 Eglinton Avenue East shown in Attachment 3 to this report and any future development of the site would be subject to further peer-review and potentially further reporting to City Council.
