3 PEOPLE ENGINEERING ENVIRONMENTS FUNCTIONAL SERVICING REPORT 120 HURON STREET CITY OF GUELPH NOVEMBER 2017 GMBP FILE: INTRODUCTION In support of the Zoning Bylaw Amendment Application for 120 Huron Street, GM BluePlan Engineering Limited have prepared this report to identify the site servicing and stormwater management requirements for the site. The topographic survey of the site was completed by ACI Survey Consultants (dated May 16, 2014). The proposed conceptual site layout was prepared by ABA Architects Inc. (November 3, 2017). 2. SITE INFORMATION The 2.51-hectare site is located at 120 Huron Street within the City of Guelph (see Figure No. 1). The site is bound by Alice Street to the north, Guelph Junction Railway lands to the east, existing development to the south and Huron Street to the west. The site currently consists of an existing four (4) storey 18,200 sq. ft. concrete and brick factory building, a two (2) storey office building and shed. The existing office building and shed will be demolished and the factory building will be refurbished into a 70 unit apartment. The remainder of the site is to be further developed with 60 townhouse units (2,000 sq. ft. each) including 18 townhouses which will front onto Huron Street. In May of 2014, ACI Survey Consultants completed a topographic survey of the site. The site was found to be generally flat with very little change in grade across the site. In general, the north half of the site drains towards Alice Street and the south half of the site generally drains towards Huron Street and adjacent lands. Under existing conditions, the site is generally flat with very little change in grade across the site. In general, the north half of the site generally slopes towards Alice Street and the south half of the site generally slopes towards Huron Street. The centerline road elevation along Huron Street, across the frontage of the site, ranges from (approximately) to (approximately). The centerline road elevation along Alice Street, across the frontage of the site ranges from (approximately) to (approximately). Based on the results of the Geotechnical Investigation performed by Peritus Environmental Consultants (dated April 2017), the soil classifications on site consists of sand, gravel, sandy gravel, and silt. The groundwater elevation within the monitoring wells ranged between m and m. PAGE 1 OF 9

4 FUNCTIONAL SERVICING REPORT 120 HURON STREET GMBP FILE: NOVEMBER PROPOSED DEVELOPMENT 3.1 Site Grading The grade and elevations of the site, along with the internal private roadways, is controlled by the elevation of the existing four storey building, the existing centerline road elevation of Huron Street and the major overland flow route through the site. The site will be graded to match the existing elevations along the property limits. Access to the site is currently provided via Huron Street. Upon development, access to the site is proposed to be provided via two (2) driveway entrances along Huron Street. 3.2 Water Supply Water supply is currently provided via a 50mm diameter water service lateral extended from the existing 200 mm diameter watermain on Alice Street. There is also an existing 300 mm diameter watermain along Huron Street. As per Section of the City of Guelph s 2016 Development Engineering Manual, cluster townhome developments require two (2) connections to the City watermains, including backflow prevention at the property limits, to create a looped connection. A looped watermain connection is proposed to be provided via the extension of two (2) - 150mm diameter watermains from the existing 300 mm diameter watermain on Huron Street. This looped watermain connection will service both the existing building and the townhouse units. As part of these works, the existing 50mm diameter water service lateral on Alice Street will be capped at the main and abandoned. To ensure adequate fire protection for both the apartment building and townhouses, three (3) on-site fire hydrants are anticipated to be required. The exact location of the on-site fire hydrants will be confirmed as part of the site plan approval process. 3.3 Sanitary Service Sanitary service for 120 Huron Street is currently provided via two (2) existing sanitary service laterals. The existing 4 storey building is currently serviced via a connection to the existing 200 mm diameter sanitary sewer on Alice Street. The existing 3 storey office building and shed are currently serviced via a connection to the existing 200 mm diameter sanitary sewer on Huron Street. Sanitary service for the existing building will be provided via the extension of a 150mm diameter sanitary sewer, ultimately discharging to the existing 250mm diameter sanitary sewer on Huron Street (northerly direction). Sanitary service for the townhouses will be provided via the extension of a 200mm diameter sanitary sewer, ultimately discharging to the existing 225mm diameter sanitary sewer on Huron Street (southerly direction). As part of these works, the existing sanitary service lateral will be plugged and abandoned at property line. PAGE 2 OF 9

5 FUNCTIONAL SERVICING REPORT 120 HURON STREET GMBP FILE: NOVEMBER 2017 The following is a summary of the anticipated sanitary sewer design flows discharging to the existing 200mm diameter sanitary sewer on Huron Street. Table 1: Proposed Development 6 L/s/ha Anticipated Sanitary Design Flow to Huron Street Anticipated Sanitary Design Flow m 3 /s Sanitary Sewer Capacity - North 1.2%) m 3 /s Proposed Development 6 L/s/ha m 3 /s Sanitary Sewer Capacity - South 0.3%) m 3 /s Therefore, in our opinion the existing 200mm and 225mm diameter sanitary sewers on Huron Street have sufficient capacity to convey the anticipated design flows from the proposed development. 3.4 Storm Service Storm service for 120 Huron Street is currently provided via a catchbasin on the south side of the four storey building which connects to the existing 300mm storm sewer on Huron Street. As part of the development, all onsite storm sewers will be sized to convey the 5-year design storm event. Major storm runoff will sheetflow overland uncontrolled towards Huron Street and Alice Street. Based on the invert elevations of the existing storm sewers on Huron Street and Alice Street, as well as the stormwater management criteria provided by the City of Guelph, the development is proposed to be serviced via the extension of two (2) 300 mm diameter storm sewer service laterals from the existing 300 mm diameter storm sewers on Huron Street. 3.5 Stormwater Management Design Stormwater Management Criteria A summary of the stormwater management criteria for 120 Huron Street, as per the City of Guelph, is as follows: 1. Post-development flow rates are to be attenuated to pre development levels for the City of Guelph s 2, 5, 25, and 100 year design storm events based on a runoff coefficient of On site control and storage (roof top/parking lot/ponds/superpipes) may be required to attenuate flows. 3. Major storms are to be routed overland to the City s R.O.W. without exceeding a maximum parking lot pond depth of 0.3m. 4. Clean runoff (roof water) should be directed to pervious areas for infiltration to encourage ground water recharge (Low Impact Development). 5. Quality control facilities (70% TSS Removal) are required to remove suspended solids (oil and grit) from areas draining driveways and parking lots. 6. Existing overland drainage patterns from adjoining properties must be maintained. PAGE 3 OF 9

6 FUNCTIONAL SERVICING REPORT 120 HURON STREET GMBP FILE: NOVEMBER 2017 The City of Guelph Chicago Rainfall Distribution parameters were used to provide the mass rainfall data. The 2, 5, 25, and 100-year design storm event results are appended. The Chicago Rainfall Distribution parameters and the total depth of rainfall for the analysis are as follows: Table 2: City of Guelph Chicago Rainfall Distribution Parameters 2-Year 5-Year 25-Year 100-Year a = b = c = r = Duration (minutes) = Depth (mm) = The Horton infiltration method was used in the runoff calculations. The parameters used in MIDUSS are as follows: Table 3: Horton Infiltration Values for City of Guelph Impervious Areas Pervious Areas Maximum Infiltration 0 mm/hr 75 mm/hr Minimum Infiltration 0 mm/hr 12.5 mm/hr Lag Constant 0.0 hr 0.25 hr Depression Storage 1.5 mm 5 mm Allowable Release Rates The allowable release rates from the site will be equivalent to the pre-development flow rates based on a runoff coefficient of 0.4. Therefore, using the Rational method, the allowable release rates from the 2.51-hectare drainage area under post-development conditions are as follows: Table No. 4: Allowable Release Rates 2-Year 5-Year 25-Year 100-Year Allowable Release m 3 /s m 3 /s m 3 /s m 3 /s Post-Development Drainage Areas For the post-development condition analysis, the site was analyzed as four (4) drainage catchments (see Figure No. 2). Catchment 100 (0.20-hectares, 100% Impervious) represents the rooftop of the existing building. Since the rooftop of the existing building is flat, and roof drains are provided under the Ontario Building Code, natural storage and attenuation of stormwater will occur. Runoff from Catchment 100 will be attenuated through the use of four (4) roof drains with six (6) weirs open per drain, based on the minimum of one roof drain every 464.5m 2 (5,000 ft 2 ) of rooftop area and that the average depth of water stored on the rooftop will not exceed the design criteria of 100 mm, with a maximum storage depth of 150 mm at the roof drains. Please note a roof drain with six (6) weirs represents a standard, fully open roof drain with no flow control features. PAGE 4 OF 9

7 FUNCTIONAL SERVICING REPORT 120 HURON STREET GMBP FILE: NOVEMBER 2017 Runoff generated from Catchment 100 will be directed to the stormwater detention structure located in the basement of the existing building, ultimately discharging to the existing 300mm diameter storm sewer on Huron Street. Catchment 101 (1.17-hectares, 90% Impervious) represents the parking areas and asphalt driving areas associated with the proposed apartment building. Runoff generated from Catchment 101 will be directed to the stormwater detention structure in the basement of the apartment building, ultimately discharging to the existing 300mm diameter storm sewer on Huron Street. Catchment 200 (0.86-hectares, 60% Impervious) represents an east portion of the site including the majority of the proposed townhouse units as well as associated parking and asphalt driving areas. Runoff generated from Catchment 200 will be directed to the on-site stormwater management facility, ultimately discharging to the existing 300mm diameter storm sewer on Huron Street. Catchment 300 (0.13-hectares, 65% Impervious) represents a southwest portion of the site. Runoff generated from Catchment 300 will sheetflow uncontrolled towards Huron Street. Catchment 301 (0.15-hectares, 55% Impervious) represents a northwest portion of the site. Runoff generated from Catchment 301 will sheetflow uncontrolled towards Huron Street and Alice Street. Quality control for stormwater runoff generated from Catchment 100 and 101 will be provided via an oil/grit separator unit (Stormceptor STC 1500, or approved equal) prior to discharge to the existing storm sewer on Huron Street. Quality control for stormwater runoff generated from Catchment 200 will be provided via an oil/grit separator unit (Stormceptor STC 750, or approved equal) prior to discharge to the existing storm sewer on Huron Street. Details of the oil/grit separator sizing have been included in Appendix A Routing Table No. 5: Catchment 100 Rooftop Stage/Storage/Discharge Capacities (Existing Building) Peak Flow (m 3 /s) Available Capacity Storage Volume (m 3 ) Storage Elevation (m) Peak Flow (m 3 /s) Actual Capacity Used Storage Volume (m 3 ) Storage Elevation (m) Rooftop Year Year Year Year Overflow PAGE 5 OF 9

Table No. 9: Comparison of Allowable Release Rates and Post-Development Flow Rates Allowable Release Rate Post Development Flow Rate 2-Year 5-Year 25-Year 100-Year m 3 /s m 3 /s m 3 /s m 3 /s m 3 /s m 3 /s m 3 /s m 3 /s Therefore, the post-development flow rates during the 2, 5, 25 and 100-year design storm events have been attenuated to less than the allowable release rates. See Appendix A for the Storm Sewer Design Calculation Sheet indicating individual sewer flows and capacities. Note that minor stormwater flows will discharge from the site via the storm sewer connection to the 300mm diameter storm sewer on Huron Street. Major stormwater flows will discharge overland to the Huron Street right-of-way. PAGE 7 OF 9

10 4. MAINTENANCE PLAN FUNCTIONAL SERVICING REPORT 120 HURON STREET GMBP FILE: NOVEMBER 2017 To ensure that the stormwater management system continues to function as designed and constructed, we recommend that the following inspections and maintenance activities be completed on an annual basis: 1. Is there any noticeable damage to the asphalt and grassed areas (i.e. erosion, blockages)? If yes, complete any necessary repairs. 2. Inspect all roof drains and associated piping. Remove and dispose of any accumulated sediment trash/litter debris (i.e. leaves). 3. Inspect the oil/grit structure and complete any necessary maintenance/repair activities as identified by the manufacturer. 4. Inspect all catchbasins and manholes. Remove and dispose of any accumulated sediment, trash/litter, debris (i.e. sediment, garbage, leaves, etc.). 5. Inspect all overflow locations. Remove and dispose of any accumulated sediment trash/litter, debris (i.e. sediment, garbage, leaves, etc.). Please note that any structures identified during the annual inspection to be worn, missing or damaged are to be repaired or replaced within 48 hours. 5. SEDIMENT AND EROSION CONTROL PLAN A silt fence will be installed along the property boundary in all locations where runoff will discharge from the site to adjacent lands. The silt fence will serve to minimize the opportunity for waterborne sediments to be washed on to the adjacent properties. Upon completion of the grading, any area not subject to active construction within 30 days will be topsoiled and hydroseeded as per OPSS 572 Once manholes, catch basins or inlet risers have been installed, the grates will be wrapped in woven geotextile filter cloth. This feature will be maintained until all building and landscaping has been completed. Inspection and maintenance of all silt fencing will start after installation is complete. The fence will be inspected on a weekly basis during active construction or after a rainfall event of 13 mm or greater. Maintenance will be carried out, within 48 hours, on any part of the facility found to need repair. Once construction and landscaping has been substantially completed, the silt fence will be removed, any accumulated sediment will be removed and the landscaping will be completed. After construction of the complete development, erosion will not occur and sediment transport will be minimal. 6. UTILITIES The proposed development will be serviced via utility connections (Guelph Hydro Inc., Rogers Cable, Union Gas, Bell Canada, Canada Post, etc.). As part of the site plan approval process for the development, the size and point of connection within right-of-ways for each utility will be confirmed. PAGE 8 OF 9
