2 Agenda Project Background Class EA Process The Problem Alternative Solutions Facilities Sites Scoring System Scoring Outcome Next Steps 2

3 Project Background EA initiated in October 2017 to investigate solutions to problems with current water storage facilities Current water storage is an elevated tank located at General Coach and in-ground reservoir on York St. Elevated tank constructed in 1935 moved to Hensall in Total volume for storage is 455m tank inspection by Landmark Municipal Services raised issues concerning corrosion with the interior and safety issues with the tank exterior. Previous studies had confirmed that the tank was too low and too small to be effective. 3

5 Municipal Class Environmental Assessment (Class EA) Planning and Design Process for Municipal Water, Wastewater and Road Projects Conducted to Evaluate the Potential Impacts of Municipal Projects and Impact Mitigation Involves Consultation with the Public, Aboriginal Communities, Regulatory Agencies, Adjacent Property Owners Requires Consideration of Natural, Social, Cultural, Economic and Built Environments 5

6 Class EA Study Phases 6

7 The Problem The existing water storage facility, servicing the community of Hensall, is not adequate. Investigations have established that the structure is both too small and too low to provide adequate pressures throughout the community and to maintain efficient operation of the water system. Furthermore, the facility is over 80 years old and requires significant repairs to maintain system functions. 7

8 Alternative Solutions Alternative 1 Construct a new water storage facility in Hensall Requires selection of storage facility type and location Alternative 2 Limit community development Alternative 3 - Do Nothing 8

9 Alternative Storage Solutions Alternative Facility Types Reservoirs Elevated Tanks Standpipes 9

10 Evaluation of Alternative Facility Types Type of Facility Reservoir Elevated Tank* Standpipe Advantages Disadvantages can be expanded minimal visual impact energy and maintenance costs require pumps to maintain pressure larger footprint gravity storage energy efficient can be a focal point in the community small footprint not expandable shadowing and visual impacts energy efficient small footprint not expandable shadowing and visual impacts not as cost efficient mechanically more complex * Preferred Storage Type 10

11 Alternative Sites Site 1: NW corner of Mill & Soldan Street Site 2A & 2B: Hensall Road East Site 3: York Street west of Oxford Existing elevated tank site 11

13 Site 2A & 2B Hensall Road Looking west sites are on the right 13

14 Site 3 School Site Looking west toward site 14

15 Required Watermain Upgrades 15

16 Scoring System Ranked sites by scoring a number of social, economic, technical and environmental impacts or factors. Each factor or impact for each site, was scored from 1 (very poor in meeting criterion) to 3 (superior in meeting criterion) Sites with higher scores were considered to have fewer potential impacts (or impacts that can be mitigated) or were judged to perform better 16

17 Factors Examined Need to purchase property Impact to adjacent properties Significant natural and/or cultural features present Disruption of natural features Impact on future development Visibility for economic development Connections to water distribution grid (more is better) Provide fire flow for areas of concern Capital costs for watermain and an elevated tank Ability to stage watermain construction Will new watermain replace inadequate watermain 17

18 Cost Summary Site Alternative Watermain Capital Cost 1 Elevated Tank Capital Cost 2 Total Site #1 Soldan Street $0 $3,165,000 $3,165,000 Site #2 Hensall Road $600,000 $3,125,000 $3,725,000 Site #3 School Site $700,000 $3,245,000 $3,945,000 Notes: 1. Includes 20% for engineering and contingencies. 2. Includes 12% for engineering and contingencies. 3. Does not include costs for 250mm dia watermain built previously on Mill Street 4. Does not include demolition costs for existing tank estimated at $100, Costs are based on 2018 construction. 18
