Residential Development on Dundas Street West

 

Site Location:
The site is strategically located on the south side of Dundas Street West, between Annette Street and Brad Street in Toronto. The total site area spans approximately 1,849 m², offering significant potential for urban development.

 

Proposed Development:
The proposed development, designed by Architects Alliance (dated November 17, 2017), features an 8-storey residential building with two levels of underground parking. The ground level includes eight townhouses fronting Dundas Street West on the north portion of the site. In total, the development comprises 110 residential units. 

 

Services Provided by N & N Engineers LTD:
N & N Engineers LTD specializes in delivering innovative and sustainable engineering solutions for urban developments. For this project, the following services were provided to ensure functional servicing, stormwater management, and compliance with municipal and environmental regulations:

 

 1. Functional Servicing Report:

Comprehensive review of the existing municipal infrastructure to assess its capacity to support the proposed development.
Detailed servicing requirements, including water, sanitary, and storm systems.

 

2. Stormwater Management Report:

The stormwater management system for the development incorporates underground retention and detention tanks to store and control stormwater, reducing peak flow and preventing sewer overload. A water balance retention tank captures and retains 5mm of rainfall for reuse, infiltration, or evapotranspiration. A stormwater treatment facility with a storm filter device removes 80% of total suspended solids before discharge. Flood flow management tanks provide 100-year storm storage, attenuating runoff before controlled release. Catch basins and trench drains collect runoff from paved areas and direct it to the underground storm tank. An emergency overflow system ensures safe drainage to Dundas Street West during extreme storm events, preventing site and neighboring property flooding. This system ensures compliance with Toronto Green Standards while enhancing water quality and flood protection.

 

3. Site Servicing Plan:

Engineering designs for water, sanitary, and stormwater connections.

 

4. Grading Plan:

Detailed grading strategies to optimize site design and drainage.

 

5. Erosion Control Plan:

Mitigation measures to minimize erosion during and after construction.

 

6. Sanitary Sewer System Analysis:

Evaluation of the combined sanitary sewer system using MOECC Procedure F-5-5 standards to ensure compatibility and capacity for the proposed development.

 

7. Groundwater Drainage System Design:

Mechanical drawings and strategies for effective groundwater drainage to support underground parking levels.

 

Purpose and Impact:
The engineering reports prepared by N & N Engineers LTD enable City staff to assess the development's impact on existing municipal infrastructure while ensuring compliance with rezoning and environmental requirements. These services showcase N & N Engineers LTD's commitment to providing cost-effective, sustainable, and innovative solutions for urban development projects.
