INTRODUCTION IBI Group was retained by Lotco II Limited to prepare this Servicing Report in support of an Application for Zoning Amendment, Site Plan, and Plan of Common Element Condominium. These applications are intended to facilitate a residential development on Block 53 of Plan 58M-379 and Part of Lot 4, R.P. 622, Ferris Drive in Wellesley. The proposed development will contain 32 semidetached units and 2 blocks of townhousing totalling 13 units all within a common element condominium, plus 3 single detached lots fronting on Ferris Drive. The purpose of this servicing report is to support the detailed site servicing and grading plans that have been completed and confirm that the proposed residential development can be serviced from the existing municipal services that were installed to service Block 53 within the Mill Creek Meadows Subdivision. 1.1 Site Location and Description The subject property is legally described as Block 53 of Registered Plan 58M-379 and Part of Lot 4 Registered Plan 622 (now Part 1, 58R-17959) Township of Wellesley, Regional Municipality of Waterloo. It is located at the northwest corner of Greenwood Drive and Ferris Drive. The subject lands are approximately ha (4.76 acres) in size and are currently vacant. The lands were pre-graded as part of the Mill Creek Meadows Subdivision development in A topsoil stockpile and other miscellaneous material piles currently exist on the site. 1.2 Proposed Development When the subdivision was created Block 53 was zoned for institutional development, but it is no longer required for the institutional use. The portion of Lot 4 which is the subject of this application is currently zoned Urban Residential (UR). Together, the two parcels are proposed to be rezoned to accommodate a condominium development with semi-detached dwellings, townhouse dwellings plus 3 single detached free hold lots fronting on Ferris Drive. The following table summarizes the proposed use of the subject lands.

SERVICING DESIGN A servicing design is required in support of the planning applications and for development of the site. The objective of this report is to support the detailed site servicing and grading design that has been completed for the proposed residential development. As well, the report will confirm that the existing municipal services that were installed as part of the Mill Creek Meadows Subdivision are adequate to service this proposed residential development since this use is different from the proposed use at the time the subdivision was developed. Along with the detailed site servicing and grading plans, this report describes how municipal services will be provided for the proposed development. The following methodology was used in preparing the servicing design: Obtained and reviewed relevant background information that was available; Consulted with Township of Wellesley staff and the Township s consultant; Prepared preliminary servicing designs for the development and determined a preferred servicing alternative; and Prepared detailed site servicing and grading plans. 2.1 Background Information Available background information was reviewed and the relevant information was used in preparing the servicing design for the proposed development. The following is a summary of the information that was reviewed: Geotechnical Investigation, Proposed Mill Creek Meadows Subdivision Chung & Vander Doelen Engineering Ltd. completed a geotechnical investigation for all of the subdivision lands that included Block 53, in January 2004, in support of the subdivision. Stormwater Management Report, Mill Creek Meadows Subdivision CCL/IBI Group completed a stormwater management report for the subdivision, in July 2005, in support of the subdivision. The report analysed the subject lands and outlined stormwater management control criteria to be applied to this site. March 2014 Page 2

6 BLOCK 53 FERRIS DRIVE PLAN 58M-379 & Part of Lot 4, Registered Plan 622 Mill Creek Meadows Subdivision Engineering Design Drawings CCL/IBI Group prepared the detailed engineering drawings and sewer design sheets for the subdivision. The for construction drawings were issued October 31, 2005 and the complete asrecorded set of drawings are dated November 16, Grading Design The lands currently drain overland from south to north and into the Campbell Drain, which then outlets to Firella Creek to the west. Existing elevations on the site vary from a high elevation of about 364.7m on the south side of the site, to a low elevation of 359.4m in the northwest corner of the site. There is one larger topsoil stockpile and several smaller piles of miscellaneous materials currently on the site, along with a berm approximately 1.0m in height fronting Greenwood Hill Road. In order to provide adequate grades for the roads and residential units on the site, a grading operation will need to be undertaken. After stripping any remaining topsoil and removing any piles of unsuitable material, on-site cut and fill, as well as imported fill, will be required to attain the required grading. The Geotechnical Investigation completed by Chung & Vander Doelen Engineering Ltd. has a section on site grading which should be reviewed prior to any grading operations. A site grading plan for the proposed development has been prepared for the site plan application. Road grades vary from 0.5% to 2.9%, which are suitable for this type of development. The grading of the lots and parcels has been designed so that minor drainage will go into the site storm sewer system and major flows will follow the road system to an overland drainage swale at the west end of the site that outlets to the Campbell Drain. The backyards of Parcels 15 to 32 will continue to drain overland to the north. 2.3 Sanitary Sewer Design A sanitary sewer was installed between Lots 48 and 49, Plan 58M-379 during the development of the Mill Creek Meadows Subdivision to service Block 53. An existing maintenance hole is located just inside the property of Block 53 which will be the connection and outlet point of the internal sanitary system. Gravity sewers, 200mm diameter, will be installed within the common element roads and along an easement. A sanitary service lateral, 125mm diameter, will be installed for each unit. The three lots fronting on Ferris Drive will have a sanitary service lateral to the sanitary sewer on Ferris Drive. See the site servicing plan for details of the sanitary sewer system. A sanitary sewer design sheet and sanitary drainage area plan have been prepared for the development. The total peak flow generated from the development has been compared with the flow determined from the subdivision sanitary sewer design sheet for Block 53. The sanitary flow from the proposed development going to the existing sewer between Lots 48 and 49 is 3.79 L/s and the flow from the subdivision design sheet is 5.70 L/s; therefore the downstream sanitary sewer has capacity for the proposed residential development. As well, the sanitary sewer and downstream sewers that the three lots on Ferris Drive outlet into have more than adequate capacity. The sanitary sewer design sheets are included in Appendix A.

7 BLOCK 53 FERRIS DRIVE PLAN 58M-379 & Part of Lot 4, Registered Plan Watermain Design A 300mm watermain exists on Ferris Drive along the frontage of Block 53. A 150mm watermain will be connected to this watermain and extended through the site within the common element roads. A 25mm water service will be installed for each unit. The three lots fronting on Ferris Drive will have a water service connection to the watermain on Ferris Drive. Hydrants will be spaced throughout the site to provide the firefighting requirements for the development. See the site servicing plan for details of the water servicing system. 2.5 Storm Sewer Design and Stormwater Management A storm sewer was installed between Lots 47 and 48, Plan 58M-379 during the development of the Mill Creek Meadows Subdivision to service Block 53. An existing ditch-inlet maintenance hole is located just inside the property of Block 53 which will be the connection and outlet point of the internal storm sewer system. Storm sewers, 250mm to 450mm diameter, will be installed within the common element roads and along an easement. A storm service lateral, 100mm diameter, will be installed for each unit. The three lots fronting on Ferris Drive will have a storm service connection to the storm sewer on Ferris Drive. A ditch-inlet catchbasin will be installed to capture drainage from the rear yards of units 1-8 and 33-39, and the future development of the adjacent property at the corner of Ferris Drive and Greenwood Hill Road; the storm sewer has been sized to accommodate the development of this property to a 0.70 runoff coefficient. See the site servicing plan for details of the storm sewer system. A storm sewer design sheet and storm drainage area plan have been prepared for the development. The total peak flow generated from the development has been compared with the flow determined from the subdivision storm sewer design sheet for Block 53. The flow from the proposed development is m 3 /s and the flow from the subdivision design sheet is m 3 /s; therefore the downstream storm sewer has capacity for the proposed residential development. The storm sewer design sheets are included in Appendix B. IBI Group has also prepared a Stormwater Management Design Brief in support of these applications and the proposed development. A copy of the Brief is included as Appendix C. 3. CONCLUSIONS This Servicing Report describes a servicing design that provides adequate municipal services for the proposed residential development at Block 53, Plan 58M-379 and Part Lot 4 R.P. 622, Ferris Drive in Wellesley. The following can be concluded: An existing sanitary sewer located between Lots 48 and 49 of the Mill Creek Meadows Subdivision will provide a sanitary sewer outlet for the site and has the capacity to service the site; An existing watermain on Ferris Drive will be connected into to provide water for the site; and The existing stormwater management pond for the subdivision has been designed to provide quantity and quality control for the stormwater runoff generated by the proposed development, March 2014 Page 4
