Re: 3353 Cambie Street, Vancouver

Rainwater Management Plan We have prepared this Rainwater Management Plan for this commercial development at 3353 Cambie Street, Vancouver, to comply with the Green Building Policy for Rezoning (Green Infrastructure Implementation Plan). System Summary The system is designed so that no additional on-site storm water will be discharged to the municipal system. This is achieved by a combination of methods that fall under Tiers 1, 2 and 3. Below are the Criteria used to determine the Rainwater Management Plan and the most stringent Criteria will be implemented at the site. 1. Retain the first 24mm of rainfall in 24 hours as listed in the Rainwater Management

Bulletin in effect since July 11, 2018. 2. Control the 5-year post-development flow to 5-year pre-development flow rate (use

2014 IDF 5-year storm event rate as pre-development and 2100 IDF 5-year storm event rate as post-development condition).

3. LEED v4 (85th percentile storm event detained).

CRITERIA DESCRIPTION VOLUME REQUIRED

1 Retain the first 24mm of rainfall in 24 hours 20.82 m3.

2 Control the 5-year, 24-hr 2014 post-development flow to 5-year 24-hr 2100 post-development flow rate

4.26 m3.

3 LEED v4 (85th percentile storm event detained)

17.88 m3.

Rainwater detention for Criteria 1 is the worst case. Thus, by addressing Criteria 1, all the remaining Criteria will be automatically addressed. An oil interceptor is added to the onsite system to achieve the 80% TSS removal as per the Rainwater Management Bulletin dated July 11, 2018.

System Based on VanMap orthophotos, the pre-development site is almost at 100% hard surface with an asphalt parking lot to the west and a relatively flat building roof to the east. Please refer to Figure 1, 2016 Orthophotos and Figure 2, 1999 Orthophotos in Appendix 1. The Preliminary Rainwater Management Plan is prepared based on the architectural layout prepared by Radiant City Architecture Inc., dated December 13, 2019, and in the absence of the onsite landscape drawing. Based on the current architectural layout and discussion with the architect, the outdoor space for the daycare on the second floor can be covered with topsoil and sod. (Tier 1). Rainwater falling on the covered outdoor area on the second floor can be directed to the landscaped area. (Tier 2). The roof drain will be directed to a stormwater detention system and the maximum release rate will be set to the pre-development rate at 0.0095 cu. m/s to satisfy City requirements. For an extreme storm event, stormwater on the second floor will be directed to the area drain in the landscaped area, which will be set 0.03m higher than the sod elevation to collect the flow. Stormwater will then be directed to the oil interceptor. A bypass system will be used to safely release the overflow to the municipal system to prevent flooding of the development. As per the water quality requirements, water (24mm for low pollutant generating surfaces like roofs, and 48mm for high pollutant generating surfaces like driveways) that leaves the site must be treated to a standard of 80% TSS removal. All water leaving the site will first be directed to a stormceptor unit to remove a minimum of 80% TSS. The proposed location of the stormceptor unit and model number has been provided in Appendix 1. The location will be confirmed during in the DP stage. A Section 219 Rainwater Management Agreement Covenant will be required once the Final RWMP is accepted by the City. The Final RWMP will be attached to the covenant and be registered on the property’s title. After construction, the Engineer of Record will be required to inspect the RWM system and determine whether it has been substantially completed according to the covenant and Final RWM plan. Please let me know if you have any questions. Yours truly, CitiWest Consulting Ltd. Peter Yue, P. Eng. Project Engineer PY/py Attach.

Calculation

Site Location: 3353 Cambie Street Total Site Area: 868 m2 Pre-development run-off coefficient calculation Parking lot 503.3 m2

Roof 364.7 m2

Total 868.0 m2

Average Runoff coefficient for the site = [503.3 x 0.8 + 364.7 x 0.85] / 868 = 0.821 Proposed development run-off coefficient calculation Landscape area on ground level: 0 m2 Patio and other hardscape area fronting Cambie Street: 73.58 m2 Patio and other hardscape area on second floor: 114.04 m2

Landscape area on second floor: 219.88 m2 Rooftop at 6th level area: 448.24 m2 Hardscape fronting Tupper Street 12.26 m2 Total Site Area: 868 m2

Average Runoff coefficient for the site = [73.58 x 0.8 + 114.04 x 0.85 + 219.88 x 0.18 + 448.24 x 0.85 + 12.26 x 0.8] / 868 = 0.6753 Criteria 1 24mm x (868m2) = 20.832 m3

Criteria 2 Refer to the excel = 4.256 m3

Criteria 3 20.6mm x (868m2) = 17.88 m3

Rainwater detention for Criteria 1 is the worst case. Thus, by addressing Criteria 1, all the remaining Criteria will be automatically addressed.

Rainwater retention (landscape on slab) Landscape area on second floor = 219.88 m2 Soil depth = 450mm Void ratio for topsoil = 0.25 Volume in soil for retention = 219.88 m3 x 0.45 x 0.25 = 24.74 m3

24.74 m3> 20.83m3 (Criteria 1)

Landscape on slab (second floor) is capable of retaining the required volume.


Release Rate The rainfall intensity, I, is based on the City of Vancouver Intensity Duration Frequency (IDF) curves and the 5-year 10-minute duration to be 48mm/hr.

Area of the site = 868 m2

Pre-development runoff coefficient = 0.82 Q5 (pre-development for 10-min event) = (0.82 x 48mm x 0.868 ha)/3600 = 9.49 L/s. Maximum release rate for post-development is set at 9.49 L/s.

Drawing Notes

1. This drawing reflects the intent of the design. Verify existing conditions and dimensions on site and report any discrepancies between drawings and site conditions to the Architect prior to construction.

2. Noted dimensions take precedence over scaled dimensions. 3. If this drawing is copied or not printed at full size, verify drawing scale

before scaling dimensions. 4. Site dimensions are approximate (refer to survey as necessary.) 5. Read drawings in conjunction with Architectural Notes, Specifications

and Site Instructions, and drawings and specifications of other disciplines, including Structural, Electrical, Mechanical, Plumbing, Civil and Interior Design. Report discrepancies or conflicts to the Architect.

6. Where conflicts arise between notes, specifications, drawings, manufacturers’ instructions, general trade practices and statutory requirements, the more stringent shall apply. In cases where the conflict impacts the cost or any visible aspect of the work, advise the Architect.

7. All proposed substitutions and deviations from drawings, notes and specifications shall be submitted in writing to the Architect for written approval prior to construction.

8. These drawings are not record drawings nor as-built drawings and may not be relied on for any purposes other than the current project.

Standards

1. All work shall conform to statutory requirements, including applicable Building, Electrical, Plumbing, Gas and Fire Codes, local Codes and Bylaws, Building Inspector requests, and Safety and Health Standards.

2. All work requiring the involvement of a professional engineer is to be carried out under the authority of an appropriate registered engineer.

3. Installation of all materials, equipment, fixtures and systems shall be done in accordance with Manufacturers’ instructions.

4. Where construction or installation requires additional elements not specifically shown in these drawing, such elements shall be deemed to be included and shall be provided.
