  1. 1. Rosehill Reservoir Rehabilitation Overview Presentation October 2016
  2. 2. Project Team • Engineering & Construction Services • Ken Koson, Sr. Project Manager • Toronto Water • Mike Brannon, Manager, Water Supply • Henry Polvi, Sr. Engineer, Water Supply • Public Consultation Unit • Kate Nelischer, Sr. Public Consultation Coordinator • Associated Engineering • Elia Edwards, Project Manager • Anna Comerton, Assistant Project Manager
  3. 3. Rosehill Reservoir - Background The open-topped Rosehill Reservoir was commissioned in 1874 with a storage capacity of 156 Million Litres of potable water. Aerial photo, 1947Open Reservoir, July 1936
  4. 4. Rosehill Reservoir – Background (cont.) In 1966, the reservoir was expanded to a storage capacity of 270.3 Million Litres and the structure was covered. Reservoir Construction, 1965 Covered Reservoir, 1975
  5. 5. Rosehill Reservoir – Background (cont.) The Rosehill Reservoir is the largest of eleven potable water reservoirs operated by the City of Toronto. • Consists of two cells (West and East) • Operates 24 hours per day and 365 days per year • Stores and distributes potable water provided by the Island Water Treatment Plant (WTP) • Primarily serves the downtown core and mid-town • One of only two reservoirs in downtown area (St. Clair Reservoir is the other)

  9. 9. Rosehill Reservoir – Rehabilitation Needs • The Rosehill Reservoir was last upgraded in 1966 • Due to the age and critical nature of the reservoir infrastructure, rehabilitation and upgrades are required to: • Ensure the structural integrity of the reservoir • Extend the service life of the reservoir • Bring the infrastructure to a state of good repair • Additionally, a new reservoir roof waterproofing membrane is required to protect the stored potable water from infiltration and contamination
  10. 10. Rosehill Reservoir – Goal The Rosehill Reservoir Rehabilitation project is a vital part of the City of Toronto’s drinking water infrastructure. The goal of this project is to bring the reservoir to a state of good repair and extend its service life. While completing this important work, Toronto Water will work with other City Divisions to consider the community’s desires for the future of the reservoir roof and maintain the public’s enjoyment of the space.
  11. 11. Rosehill Reservoir Rehabilitation Project - Design Phase Design Kick-Off Tender Fall 2015 Winter 2017 Fall 2016 Spring 2016 Winter 2016 Summer 2016 Design Phase Spring 2017 Throughout the design phase, the project team delivered notices, sent information to the project email list, updated the project webpage, posted site signage, and met with stakeholder groups (including the SRA board and the Rosehill Garden volunteers).

  14. 14. Construction Phase 1 – Pedestrian Access (Approx. Summer 2017 to Summer 2018) Temporary concrete walkway (pending TRCA approval) Existing pedestrian crosswalk Existing pedestrian crosswalk Sidewalk on north side of Rosehill Ave. (sidewalk on south side will be closed throughout construction) Perimeter pathway Little Park East Cell operating to maintain water supply Park over West Cell closed and West Cell not operating Access point for deliveries to Valve House Temporary site access point for storm sewer rehab to minimize tree impact Main site access point
  15. 15. Construction Phase 2 – Pedestrian Access (Approx. Summer 2018 to Winter 2019) Perimeter pathway Little Park Park over East Cell closed and East Cell not operating Park over West Cell closed but West Cell operating Temporary concrete walkway (pending TRCA approval) Existing pedestrian crosswalk Existing pedestrian crosswalk with push- button activated lights Sidewalk on north side of Rosehill Ave. Access point for deliveries to Valve House Main site access point Temporary closure of playground required during Phase 2 to safely accommodate storm sewer rehab (approx. 4 months)
  16. 16. Construction Phase 3 – Pedestrian Access (Approx. Winter 2019 to Fall 2020) Park pathway Little Park Park pathway (open upon re-opening of portion of park over West Cell) Access via pathway to East and South of Reservoir from Rosehill Ave. restored during Phase 3 (weather dependent) West Cell operating Park over East Cell closed and East Cell not operating Temporary concrete walkway (pending TRCA approval) Existing pedestrian crosswalk Existing pedestrian crosswalk with push- button activated lights Sidewalk on north side of Rosehill Ave. Access point for deliveries to Valve House Playground open Main site access point
  17. 17. Challenges With any construction project, some dust and noise is inevitable. The contractor will be responsible for ensuring the work area is kept cleaned with weekly sweeping and wetting of the site and roads. Every effort will be made to reduce inconveniences to the community.
  18. 18. Truck Traffic During Construction Trucks will be required to dispose of some of the soil from the top of the reservoir and bring new soil when the work is done. The City is working to minimize the impacts of truck traffic on the neighbourhood using the following measures: • Approximately 40% of soil will be reused on-site • Trucks will follow a route designed to minimize disturbance • A maximum of three trucks per hour will be permitted • Truck traffic will be restricted to Monday to Friday between 7 am and 7 pm, as per City by-laws • Daily road and sidewalk cleaning will be implemented
  19. 19. Tree Removal and Protection Of the 258 trees within the reservoir area: • 189 trees will be preserved; • 14 trees will be removed in 2016 by City of Toronto Forestry due to Emerald Ash Borer (not related to the Rosehill Reservoir Rehabilitation) • Approximately 55 trees will be removed and replaced. We are confident the 189 trees can be preserved using a variety of construction techniques. Removed trees will be replaced as per City policy. Trees will not be replanted on top of the reservoir roof. We have tried to balance the need to improve the reservoir to provide safe drinking water with the preservation of the tree canopy.
  20. 20. Tree Removal and Protection (cont.) • Routine tree pruning within anticipated construction limits performed by City of Toronto Forestry until construction begins • The project team is working with staff managing memorial program to address any memorial trees, benches or rocks requiring removal and contacting sponsors.
