1.0 Introduction

1.1 SITE INFORMATION & PURPOSE OF REPORT

RioCan Estate Investment Trust is proposing to rezone a lot located on the south west corner of Stony Plain Road and 149 Street within the West Jasper Place neighbourhood to DC2. The site is currently zoned as CB1 in the City of Edmonton. This sanitary and storm servicing study has been prepared on behalf of the client for the 4.291 ha redevelopment located in Lots 5-8 Block 61 Plan 9022422.

The site is proposed to be a mixed-use development consisting of public spaces and amenity areas, low to high-rise residential buildings and retail commercial spaces.

Specifically, this report shall provide an inventory of existing storm and sanitary outlets from the site and considers the capacity of the downstream sewer systems.

The purpose of this report is to assess the storm and sanitary flows anticipated to discharge from the subject site and to seek acceptance from the City of Edmonton for the proposed servicing strategy.

1.2 EXISTING CONDITIONS

The subject site is currently comprised of several commercial areas and parking spaces which encompass a total area of approximately 4.291 ha. The subject site is primarily surrounded by residential areas to the south and west and other commercial and institutional areas to the north and east. See Figure 1 for an aerial image of the areas and site location plan.

1.3 BACKGROUND INFORMATION

The information presented in this report is based on the review of the following information:

As-constructed drawings on file with the City of Edmonton for the external services on bordering roads (Stony Plain Road, 151 Street, 100 Avenue, 149 Street).

City of Edmonton Design Standards and Specifications

Stony Plain Shopping Centre Site Plan – Mechanical and Storm Water Management (Descon Mechanical Ltd., July 1990)

2.0 Storm Servicing

2.1 APPROACH TO DOWNSTREAM STORM CAPACITY REVIEW

Below is an analysis of the existing storm system for the subject site, followed by an analysis of restricted post development stormwater flow. This section outlines the anticipated changes in stormwater flow to the system, models the existing storm system and provides recommendations for site servicing based on an interpretation of the downstream capacity.

2.2 EXISTING STORM SERVICE AND PRE-DEVELOPMENT FLOW

As per the background information mentioned above, the existing site is comprised of impervious surfaces. The overland drainage is split and is directed to different catch basins which then drains to manholes complete with orifices that restricts the flow at the outlet.

See Figure 2 Appendix A for the existing sewer and services locations. Existing catch basin and orifice information were used to calculate the pre-development storm flow as summarized in Table 1. An assumption of 0.35 m maximum ponding above the lowest catch basin for each drainage basin was used to back calculate the existing discharge control rate. Detailed pre-development flow calculations can be found in Appendix A. The average calculated current-development controlled flow from the site area of 4.291 ha is 26.63 L/s/ha for a total controlled release of 114.25 L/s.

2.3 POST-DEVELOPMENT FLOW

In accordance with City policy (Drainage Servicing Report – Terms of Reference), all storm servicing of the site will be subject to peak stormwater runoff control at an allowable discharge rate equal to the pre-development flow of 26.63 L/s/ha. The future development was assumed to have a post-development runoff coefficient of 0.95, which is representative of the subject site based on preliminary concepts. Table 2 summarizes the post-development storm flow calculations and detailed calculations can be found in Appendix B. See Figure 3 in Appendix B for an overview of the storm servicing.

2.4 STORAGE VOLUME

To achieve the flow attenuation necessary for the post development flow, the site will require onsite stormwater storage. The storage volumes per storm event scenario within the City of Edmonton Design and Construction Standards were calculated and are summarized in Table 3. To provide a conservative estimate of the amount of stormwater storage potentially required, the governing 100-year storm event was used to determine the onsite stormwater storage required for the allowable discharge rate of 26.63 L/s/ha for the proposed development. Detailed storage calculations can be found in Appendix B.

2.5 PROPOSED STORM SERVICING LOCATION AND STORMWATER FLOW CHANGES

The controlled peak outflows from Phase 1, 2, 3, and 4 shown in Table 2 will ultimately discharge into the existing storm sewers located adjacent to the four Phases. See Figure 3 in Appendix B for an overview of the storm servicing.

The onsite storage can be provided by way of several options or combination of options such as rooftop storage or onsite underground storage tanks. As well, a flow control mechanism, for example an orifice plate, may be required for tie-in to the city system. Another option is to implement LID (Low Impact Development) in the redevelopment which can reduce the volume of stormwater runoff. This will be addressed further at the detailed design stage and based on the actual site development and servicing location plans.

2.6 IMPACT TO EXISTING DRAINAGE NETWORK

The capacities of the receiving storm sewers are shown in Table 4.

The allowable site discharge during the 1:5 year storm event for Phase 3 would be 37.97 L/s into MH236723 with a pre-development controlled discharge at Orifice D of 39.64 L/s. Based on the calculations shown in Table 2, the post development for Phase 3 would use 35.2% of the available capacity in the existing 375 mm storm sewer in 100 Avenue while the pre-development flow used 36.7% resulting in a slight decrease. Based on the calculated stormwater flows shown in Table 4 and that there is no upstream flow entering the system other than local pickup, it is determined that there is remaining 70.03 L/s available capacity in the receiving storm sewer main and therefore should not have capacity issues.


August 21, 2019


The allowable site discharge during the 1:5 year storm event for Phase 4 would be 20.61 L/s into MH233805 with a pre-development controlled discharge at Orifice A into 600mm pipe downstream of MH233805 of 29.92 L/s. Combined with Phase 3 flows, the discharge would be 58.58 L/s compared to a pre-development flow of 69.56 L/s. Based on the calculations shown in Table 2, the post development flow for Phase 3 & 4 would use 21.5% of the available capacity in the existing 600 mm storm sewer in 151 Street compared to a pre-development flow utilization of 25.6% before draining into the existing 1500 mm storm sewer.

The allowable site discharge during the 1:5-year storm event for Phase 1 & 2 would be 58.58 L/s into MH 252038 with a pre-development controlled discharge to Orifice B of 29.56 L/s. Combined with Phase 3 & 4 flows the discharge would be 114.26L/s compared to a pre-development flow of 99.12L/s. This increase is due to the larger area of the site being directed to this area which was initially discharged to a different basin (Orifice C – 15.13L/s). Based on the calculations shown in Table 2, the post development for Phase 1-4 would use 0.98% of the available capacity in the existing 1800 mm. This compares to the pre-development that used 0.86%. Based on the City’s policy (Drainage Servicing Report – Terms of Reference), there should be no further analysis required for proposed peak storm flow contributions less than 10%.

Discharge to 149 Street has been removed due to capacity issues for the 250 mm storm service that we were tying into. This would remove 15.13 L/s of storm flow from the system.

3.0 Sanitary Servicing

3.1 APPROACH TO DOWNSTREAM SANITARY CAPACITY REVIEW

Below is an analysis of the existing sanitary system for the subject site, followed by an analysis of the proposed sanitary contributions with the redevelopment. This section outlines the anticipated changes in sanitary flow to the system and provides recommendations for site servicing based on an interpretation of the downstream capacity.

3.2 EXISTING SANITARY SERVICES

Based on the available drawings, it was identified that the commercial spaces on the west side of the subject site are currently serviced to the 525 mm sanitary sewer in 151 Street which drains northward. The commercial spaces on the east side of the subject site are currently serviced to the 200 mm sanitary sewer in 149 Street which drains southward to 100 Avenue then westward towards 151 Street. The commercial spaces on the north side of the subject site are currently serviced to the 200 mm sanitary sewer in Stony Plain Road which drains westward to 151 Street then continues north.

The existing dry weather flow was estimated based on the gross floor areas, current land uses, and flow data taken from the Edmonton Design and Construction Standards. The sanitary flows contributed by the existing development are summarized in Table 5 below and detailed calculations are presented in Table 8 of Appendix C.

3.3 PROPOSED SANITARY SERVICING & REDEVELOPMENT SEWAGE FLOW

Jasper Gates is proposed to be redeveloped into low to high-rise residential buildings with commercial and retail spaces. The proposed sanitary servicing & redevelopment sewage flow for each site is based on the following latest concept information available at the time of this report:

Phase 1 – Total of 360 residential units and approximately 8,200 m2 of potential commercial/retail space



Phase 4 – Total of 120 residential units

The sanitary flows contributed by the proposed development are summarized in Table 6 below and detailed calculations are presented in Table 9 of Appendix C.

Under the proposed conditions, the sanitary services for all Phases will tie into the existing sanitary sewers adjacent to the site. In comparing the pre-development and post development sanitary flows, Phase 1-4 will result in a total increase of sanitary flow due to the increase in residential and commercial spaces. Figure 4 in Appendix C illustrates the proposed sanitary servicing strategy.

Phase 1 will generate sewage flows of 21.03 L/s compared to the current development flow of 8.58L/s. From pipe section MH 252058 to MH 252059 this is 3.0-9.6% of the receiving 525mm pipe capacity, before combining with Phase 2 flows.

Phase 2 will generate sewage flows of 15.10 L/s compared to the current development flow of 9.61L/s. From pipe section MH 252063 to MH252059 this is 42-65.7% of the 200mm pipe capacity, before combining with Phase 1 flows. No additional flows are present in this section of pipe.

Phase 1 & 2 combined will generate of sewage flow of 36.13L/s compared to the current development flow of 18.19L/s. From pipe section MH252059 to MH252078 this is 9.95 -22.4% of the 525/600mm pipe capacity. After MH252078 the sanitary discharges in the 1500mm sanitary trunk running south along 151Street.

Phase 3 will generate sewage flows 20.83L/s at MH 238279 compared to the current development flow of 20.73L/s (Ex Area 3 & 4 combined). In addition, 9.71L/s of existing sanitary flow will be removed between MH 241828 to MH 238279. From pipe section MH 238279 to MH311051 this flow will use up 66.1% of the 250mm pipe capacity. An additional 4.12L/s of flow was calculated to come from upstream flows bringing the total capacity being used to 79.2%.

Phase 4 will generate sewage flows of 2.59L/s at MH311051 where combined with Phase 3 flows will total 23.42L/s. From pipe section MH311051 to MH 238274 where it ties into the 1500mm sanitary trunk running south this flow will use up 10.5% of the 525mm pipe capacity.

4.0 Conclusion

This report was prepared to provide an assessment of the storm and sanitary servicing and the anticipated effects of sanitary flow and storm discharge from the redevelopment of the Jasper Gates site located corner of Stony Plain Road and 149 Street and to provide context for future discussion.

Phase 1 storm service will tie into MH252038 and will drain to an existing 1800 mm storm sewer pipe in Stony Plain Road. An onsite stormwater storage of approximately 693.53 m3 is recommended with a 26.63 L/s/ha allowable discharge rate. The sanitary service will tie into MH252058 and will drain to an existing 525 mm sanitary sewer pipe in 151 Street.

Phase 2 storm service will tie into MH252038 and will drain to an existing 1800 mm storm sewer pipe in Stony Plain Road. An onsite stormwater storage of approximately 268.76 m3 is recommended with a 26.63 L/s/ha allowable discharge rate. The sanitary service will tie into MH141063 and will drain to an existing 200 mm sanitary sewer pipe also in Stony Plain Road.

Phase 3 storm service will tie into MH236723 and will drain to an existing 375 mm storm sewer pipe in 100 Avenue. An onsite stormwater storage of approximately 656.25 m3 is recommended with a 26.63 L/s/ha allowable discharge rate. The sanitary service will tie into MH238279 and will drain to an existing 250 mm sanitary sewer pipe in 100 Avenue.

Phase 4 storm service will tie into MH238305 and will drain to an existing 600 mm storm sewer pipe in 151 Street. An onsite stormwater storage of approximately 314.25 m3 is recommended with a 35 L/s/ha allowable discharge rate. The sanitary service will tie into MH311051 and will drain to an existing 1500 mm sanitary sewer trunk in 151 Street.

The total proposed stormwater discharge will stay the same at 114.25 L/s. As the average pre-development discharge of 26.63L/s/ha will stay the same post development. The total proposed sanitary flows generated by the redevelopment will result in an increase from 38.92 L/s to 59.55L/s. This increase is due to the added commercial and residential spaces in the subject site. These increases are negligible considering that there is available capacity remaining in the downstream sewer trunks based on the calculations.

We trust this meets with your requirements and the City can confirm and provide acceptance of the proposed servicing strategy presented in this report.
