EXECUTIVE SUMMARY

A Terms of Reference (TOR) was previously submitted in October 2015 as part of the initial submission to

the Town. Following that, a revised TOR was submitted in May 2016 as part of the second submission of

the EIR/FSS for the subject lands (Appendix 5). This updated November 2016 TOR has been further

revised for the updated and revised November 2016 EIR/FSS document.

This updated TOR document responds to comments received from the Town of Oakville and Conservation

Halton (CH) dated October 12th, 2016 and October 13

th, 2016 respectively.

This TOR focuses on the OGDI subject lands which was determined through existing information obtained

from the approved Taplow Creek, Glen Oak Creek, and 16 Mile Creek EIR/FSS as prepared by Stantec

Consulting Ltd. (December 12, 2010). The EIR/FSS was prepared for the new Oakville Hospital and a

District Energy Site located on lands to the west and north of the Oakville subject lands.

This TOR also takes into consideration the updated report to the EIR/FSS as prepared by WalterFedy

(May, 2012) which focused on the hydrologic modelling component of the stormwater management pond

for the hospital lands and the external Regional Detention Facilities (RDF).

The TOR for the Oakville Green Health Sciences and Technology District EIR/FSS has been prepared by

MMM Group Limited and WalterFedy to address the following:

(i) Hydrogeology;

(ii) Stormwater Management;

(iii) Ecology; and,

(iv) Servicing.

It is to be noted that the information as included in this TOR is provided for the revised November 2016

EIR/FSS addendum which will be a stand-alone addendum document. The November 2016 EIR/FSS

addendum document will focus on the Glen Oak and serve as an addendum/supplementary document to

the approved 2010 EIR/FSS for the Hospital Development and District Energy Site.

The EIR/FSS addendum and Stormwater Management Report will be completed to the satisfaction of the

Town of Oakville, Conservation Halton and Halton Region prior to Draft Plan Approval.

1.0 INTRODUCTION

Oakville Green Development Inc. (OGDI) has retained MMM Group Limited (MMM), MHBC Planning,

Urban Design & Landscape Architecture and WalterFedy to coordinate planning approvals for a proposed

development on the north side of Dundas Street West, east of Third Line within the Town of Oakville.

MHBC submitted a Regional Official Plan Amendment (ROPA), Official Plan Amendment (OPA), Zoning

By-law Amendment (ZBLA), applications with supporting studies, which are required by the Town of

Oakville for a complete application under the requirements of the Planning Act. WalterFedy has been

retained to complete the stormwater management component of the EIR/FSS in conjunction with MMM.

Applications were made to the Town of Oakville for a ROPA, OPA and ZBLA in October of 2015. A

complete application notice was issued by the Region on January 6th, 2016.

OGDI is proposing the creation of a Health Sciences and Technology District in the Town. The District is

intended to function as a unique growth area focused around the new Oakville hospital that will provide for

an innovative employment community consisting of development that supports the health sciences,

engineering and technology sectors, as well as integrated, supportive uses. This District will be

implemented throughout three phases and will achieve approximately 12,600 jobs and 3,150 residents for

the Town and Region. Figure 1 below shows the location of the subject lands.

1.2 Development Proposal

The proposed development consists of a Health Sciences and Technology District adjacent to the newly

constructed Oakville hospital. The proposal will include a total of 3 phases, which will include a mix of

employment use, office use, residential use, commercial and retail use, luxury condominium use, hotel

and conference centre uses, medical and assisted living uses, and a Technology Innovation Center.

The site is proposed to be divided into five main blocks. The five development blocks within the District

have been designed to attract and accommodate a variety of uses. The mix of uses has been developed

in accordance with the Town and Regional policy directions to provide for a predominance of primary

employment uses followed by secondary employment uses and residential uses.

Primary Job Uses will include such uses as technology, institutional uses, and office uses. Secondary Job

Uses will include such uses as rehabilitation, transition and long term care facilities, hotels, and retail and

service commercial uses. Lastly there are residential uses. This mix of land uses will meet the desired

ratio of 3 primary jobs to 1 secondary job to 1 resident where primary and secondary jobs are the drivers

of the application.

The central block in the District is to be developed as the Technology Innovation Centre of the District.

This Technology Innovation will be constructed as part of Phase 1.

1.3 Document Approach

The approach to the EIR/FSS addendum document is to include an executive summary which will pull

together the various components of the document. The report will also include appendices which will serve

as stand-alone reports.

Each component as described in this TOR will be included in the overall EIR/FSS.

2.0 HYDROGEOLOGY

As noted, a scoped EIR/FSS was prepared by Stantec Consulting Ltd. (December 12, 2010) for the new

Oakville Hospital and a District Energy Site located on lands to the west and north of the subject lands.

While the 2010 EIR/FSS did carry out some works the OGDI lands (a single borehole/monitoring well

located at the south part of the subject lands), it was understood by the EIR/FSS’s authors that “when

ORC proceeds with the development of these lands that a further and more detailed EIR/FSS will have to

be completed to the satisfaction of the approval agencies.” The hydrologic component of the study will

follow the ‘Requirements for Completion of Hydrogeological Studies to Facilitate Conservation Halton’s

Reviews’ guideline, Conservation Halton (November 2014).

Subsequent to the publication of the Stantec EIR/FSS, the new Oakville Hospital has been built, no work

has been carried out at the formerly proposed District Energy site, and the proponent’s site has been

regraded with the addition of fill materials, and the construction of a large, L-shaped, stormwater

management pond in the centre of the lands (the Glen Oak Regional Detention Facility).

The purpose of the hydrogeological report for the Oakville Green Health Sciences and Technology District

will be to update the information contained in the original scoped EIS/FSS report as prepared by Stantec

and to study the proponent’s lands in greater detail than was the case at the time of the original report.

Additional information regarding the Provincially Significant Wetland (PSW), located to the north of the

proponent’s lands will also be collected as requested by CH via email on September 16th, 2015.

The hydrogeological study shall be scoped, but shall also include lands extending beyond the proponent’s

property that also provide contributions to the PSW. The study shall meet the requirements outlined in the

Town of Oakville’s North Oakville Environmental Implementation Report and Functional Servicing Study

Terms of Reference (Revised May 2013). Although our study is to be scoped, the potential of the

proposed development and other development properties to affect the PSW, will be examined, and if

negative effects are anticipated, then the report will also discuss measures to mitigate such effects to the

wetland (access to the Provincially Significant Wetland will require that permission to enter be received

from CH).

The following is proposed as part of the Hydrogeology works:

(i) A review of available background studies and reports will be carried out. The original EIR/FSS

report will be thoroughly reviewed as part of this activity;

(ii) A field program will be developed to characterize the existing hydrogeological conditions at the

subject lands and within the PSW. The field activities will include site inspections and the drilling

of an adequate number of boreholes equipped with monitoring wells and mini-piezometers to

permit seasonal groundwater level monitoring, water quality sampling and hydraulic conductivity

testing. Groundwater monitoring would be carried out quarterly in order to collect one year’s worth

of data at the site, supplemented with continuous data logger readings at selected monitors and

mini-piezometers.

Figure 2, Proposed Borehole Monitoring Wells and Mini-Piezometers provides the location of the

borehole monitoring wells and mini-piezometers that are in place on the site and at the adjacent

PSW.

Six existing borehole and monitoring well locations are installed as part of this TOR, identified as

MMM15-01 to MMM15-06. Three existing monitoring wells from a previous environmental site



1415034-001

5

assessment study are located at the southwest and identified as SE-MW-101 to SE-MW-103 and

data from these wells will be utilized by MMM in our hydrogeological study. Two monitoring wells

from the original EIR/FSS are also shown on the figure: MW104-08 no longer exists having been

covered over by fill materials, while MW105-08 currently exists (permission to access this well

from the owner would be required).

Seven mini-piezometer locations are present within the PSW, with six of these locations

constructed from previous investigations. MP15-01 is a mini-piezometer station that has been

installed as a nest, with both shallow and deeper mini-piezometers along with a surface water

level monitoring station.

Figure 2 - Proposed Borehole Monitoring Wells and Mini-Piezometers

(iii) The collected field data would be assessed and used in subsequent analyses such as the water

balances, including a feature based water balance of the PSW, and to provide evidence of the

existing conditions at the site and at the PSW. The field data we collect would also be compared

against previous data collected by Stantec for their EIR/FSS to confirm if conditions at the site

have remained the same or have changed after the placement of the fill on site

(iv) An updated water balance analysis would be prepared for the proponent’s lands incorporating the

results of the field data from the subject lands, and incorporating the proposed site plan. Pre-

development and post-development infiltration volumes would be calculated based on existing

and future site conditions;

(v) A feature-based water balance analysis would be prepared for the PSW incorporating the results

of the field data from the subject lands and adjacent lands where available, and incorporating the



1415034-001

6

proposed site plan, and plans, as available, for developable lands beyond the proponent’s site.

Pre-development and post-development infiltration volumes would be calculated based on existing

and future site conditions; and,

(vi) A report will be prepared and submitted that describes the regional hydrogeological setting, details

the field activities carried out on the subject lands, identifies the site specific hydrogeological

conditions, discusses the water balance and the implications of development on the local setting

(e.g., the Provincially Significant Wetland), provides recommendations for mitigation measures

and LIDs, construction constraints (e.g., anticipated dewatering needs, construction into the water

table, etc.). The report will be sufficiently detailed to be used in support of a Draft Plan

application.

Infiltration Approach

It should be noted that there will be limited infiltration opportunities on the subject lands due to the

proposed underground parking to be situated below the entirety of the subject lands.

A review of potential infiltration methods suitable to the site will be carried out and recommendations will

be made as to viable methods to be used on site and their locations.

3.0 FUNCTIONAL SERVICING STUDY

An Area Servicing Plan (ASP) was prepared by WalterFedy (June 2014) for the Sixteen Hollow

Employment Area and has been approved by the Region of Halton. This report outlines the Regional

water and wastewater servicing for the area, including the subject lands. Based on initial discussions with

the Region, it is our understanding that an update to the approved ASP is not required for the

development of these lands. Instead only a Functional Servicing Study (FSS) will be prepared to address

the serviceability and impact of the proposed development.

The FSS will address municipal servicing (water distribution, wastewater collection and stormwater

drainage) and grading. It will adhere to Town of Oakville requirements for such a report, as well as the

Region’s requirements for ASP documents. The report will build off of the approved ASP as noted above,

in order to confirm that the established servicing strategies can accommodate the proposed increase in

density on the subject lands. As such, the water and wastewater sections of the report will effectively

serve as updates to the ASP and satisfy the Region in this regard.

As requested by the Region of Halton via email on September 14th, 2015, the FSS will address the

servicing requirements for the local watermains and local wastewater mains that will be required to service

this development internally The local watermain and wastewater system will be determined conceptually,

sized, etc.

The FSS will address the phasing of the development as well as any potential dead-end

watermains/looping (which will not likely be proposed) and how this will impact the proposed local

servicing as requested by the Region.

With regards to the future extension of Proudfoot Trail, and any potential connections requiring servicing,

future coordination will need to occur with Graydon Banning Ltd. (Mattamy Homes).

The updated Functional Servicing Study does not address the proposed crossing of areas regulated by

CH at this time as requested by CH via email on September 16th 2015.

Water Servicing

The water servicing portion of the study is to incorporate the following:

1) Existing Water System Analysis

a) Identify the existing system and improvements required based on forecasted growth.

2) Proposed Water System

a) Develop a preliminary plan for the trunk water infrastructure;

b) Perform a modeling analysis of the water system; and,

c) Identify opportunities and constraints.

3) Proposed Water System Development Charge (DC)

a) Review land requirements (if any) for proposed works;

b) Review cost and timing of DC infrastructure; and,

c) Identify potential Municipal Class EA projects.



1415034-001

Wastewater

The wastewater portion of the study is to incorporate the following:

1) Existing Wastewater System Analysis

a) Identify the existing system and drainage areas impacted by the development; and,

b) Identify opportunities and constraints.

2) Proposed Wastewater System

a) Develop a preliminary drainage and servicing plan for the trunk wastewater infrastructure;

b) Perform an analysis of the wastewater system to determine sizing and phasing; and,

c) Review Alternate designs.

3) Proposed Wastewater System Development Charge (DC)

a) Develop preliminary plan and profile drawings for DC sewers;

b) Review land requirements (if any) for proposed works;

c) Review cost and timing of DC infrastructure; and,

d) Identify potential Municipal Class EA projects.

Stormwater Drainage

The stormwater drainage portion of the study is to incorporate the following:

Proposed Stormwater Drainage System

a) Develop a preliminary drainage and servicing plan for the major stormwater infrastructure;

b) Perform an analysis of the stormwater system to determine sizing and phasing; and,

c) MMM servicing will work with WalterFedy with respect to the Stormwater Management Design.

Grading

A preliminary grading analysis will be performed to ensure the development of the subject lands is

consistent with the natural heritage system constraints and the stormwater management requirements for

the lands. Grading will take into consideration the boundary conditions such as existing and proposed

right-of-ways, the existing stormwater management pond, existing watercourses, significant slopes,

woodlots and adjacent wetlands and floodplains. The proposed grading will consider the ability to service

and grade the future development blocks. Ideally, a cut/fill balance with minimal earth movement will be

achieved with minimal rock cut required into the underlying shale bedrock. Grading analysis will be

completed in accordance with Section 3.4 of the May 2013 North Oakville EIR/FSS Terms of Reference

document.

4.0 STORMWATER MANAGEMENT (WalterFedy)

WalterFedy has prepared the following TOR to assist in preparation of a site plan design that would

support a reduction in the size of the Glen Oak Regional Detention Facility (RDF) on the subject lands.

The Stormwater Management Report will detail monitoring and reporting requirements within the

appendices of the report as per Section 4.0 of the May 2013 EIR/FSS Terms of Reference document.

WalterFedy previously prepared an update to the approved 2010 EIR/FSS for the New Oakville Hospital

as part of the Hospital Infrastructure Partnership (HIP) with EllisDon. The updated information pertained to

a hydrologic analysis of the stormwater management pond for the hospital lands. This EIR/FSS update

provided the analysis and design to support the design and construction of the Glen Oak RDF. This report

was extensively reviewed by the Town of Oakville and Conservation Halton. The EIR/FSS in support of

the hospital development is complete at this time and has been approved and adopted by the Town of

Oakville and Conservation Halton to support future development within the delineated Taplow, Glen Oak,

and 16 Mile Creek watersheds.

As background, in preparation of WalterFedy’s previous design on behalf of HIP, WalterFedy made formal

submissions to the Town of Oakville and Conservation Halton considering the anticipated development of

the contributing drainage area and the Hospital.

In reviewing their design, WalterFedy notes that the formally approved design of the Glen Oak RDF

utilizes approximately 60% of the available capacity in the Glen Oak Pond. The objective of this redesign

will be to more efficiently utilize the land area to support the maximum development potential of the

employment lands around the present Glen Oak RDF.

The following outlines the TOR which will be conducted as part of the Glen Oak RDF:

(i) Technical Analysis and Design

WalterFedy proposes to prepare the hydrologic analysis and provide re-configuration design input for the

Glen Oak RDF based on site plan layouts provided by other members of the project team. Preparation of

the revised analysis will consider the following:

The District Energy Site may be used to provide both regional and on-site stormwater

management that will support reduced storage requirements on the OGDI lands;

Prepare a conservative detention storage design that does not rely on Low Impact Development

(LID) techniques beyond capture of the first 12 mm of runoff from each roof top surface and the

assumption that approximately 50% of each roof area is occupied by a green roof system.

Assumption that the pond block on the Oakville Hospital site will be decommissioned and the

stormwater runoff from the east side of the site will be redirected to the municipal pond proposed

on the OGDI lands; and,

Optimization of the pond size to provide the required storage volume to effectively treat

stormwater runoff in the watershed.

The analysis will be prepared considering an ultimate development condition. Intermediate development

conditions will be developed that consider critical stages of development within the watershed in

subsequent detailed submissions. Definition of these development scenarios will be finalized with input

from the Town of Oakville and Conservation Halton. The scenarios are presently summarized as follows:



1415034-001

10

Pre-Development Conditions – this is the pre-development model approved in the original Stantec

EIR/FSS used as a comparison benchmark for all other scenarios when assessing impacts.

Existing Conditions – this scenario considers the current development conditions around the Hospital. The

Hospital is fully developed with a private stormwater management pond. The lands tributary to both the

Taplow Creek RDF and Glen Oak-16 Mile Creek RDF are fully graded and stabilized. Hospital Gate has

been constructed to Burnhampthorpe Road William Halton Parkway (two-lane roadway). Third Line has

been extended to ErinoaksKids Development which is fully developed.

Existing (Pre-HHS Development) Conditions – this is the pre-development model approved in the original

Stantec EIR/FSS used as a comparison benchmark for all other scenarios when assessing impacts.

Current Conditions – this scenario considers the current development conditions around the Hospital. The

Hospital is fully developed with a private stormwater management pond. The lands tributary to both the

Taplow Creek RDF and Glen Oak-16 Mile Creek RDF are fully graded and stabilized. Hospital Gate has

been constructed to William Halton Parkway (two-lane roadway). Third Line has been extended to

ErinOaksKids Development which is fully developed.

Interim Scenario 1 – this scenario considers build out of the Hospital, and the Oakville Green Development

lands are graded. The Glen Oak RDF has been reduced in volume and altered as part of the site plan for

the Oakville Green Development and the municipal pond on the District energy Lands has been

constructed and the plug is removed from the upstream end of the Glenorchy diversion channel. Mattamy

Homes lands are assumed to be 50 percent developed. William Halton Parkway has been expanded from

a 2-lane to 4-lane roadway. The pond configuration represents the ultimate pond sizing and design and

any supporting stormwater management measures are in place. Orifices at the outlet of any stormwater

management measures have been sized to meet the design criteria with the limited contributing

impervious drainage area.

Interim Scenario 2a – This scenario considers Phase 1A and 1B development of the Oakville Green

Development lands (approximately 60 percent). The Oakville Hydro (former District Energy) lands are

developed. The employment lands are assumed to be 70 percent developed during this scenario. The

Mattamy Homes lands are assumed to be fully developed. The section of William Halton Parkway east of

Third Line has been extended including the 16 Mile Creek bridge structure.

Interim Scenario 2b – This scenario considers Phase 2 development of the Oakville Green Development

lands (approximately 80 percent buildout). The employment lands are fully developed. The Oakville Hydro

(former District Energy) lands are developed. William Halton Parkway has been extended east and is

developed between the Oakville Green Development lands and Oakville Hydro lands. The Mattamy

Homes lands are assumed to be fully developed.

Ultimate Scenario 3 – This scenario considers a fully-developed Oakville Green site with all other

parameters the same as Scenario 2c. This scenario is the ultimate build out scenario and considers full

build out of the Hospital, the Oakville Green Development lands, the Employment Lands to the north, the

community park, the District Energy Site, Mattamy Homes, and Halton Healthcare has decommissioned

the on site pond.

The design will be undertaken utilizing alternative pond configurations, stage-storage-discharge

relationships, and modifications to the contributing drainage areas to account for the anticipated

development area and reduced pond footprint. The analyses will consider both a design storm approach

as required by the Town of Oakville, and a continuous analysis as required by Conservation Halton.



1415034-001

11

WalterFedy’s tasks for preparation the detention facility design are summarized as follows:

Prepare grading plan and stage-storage relationships for the proposed stormwater management

option;

Prepare hydrologic model (event and continuous simulations);

Iterate model to develop appropriate outlet configurations for each facility;

Obtain agreement the proposed stormwater management approach in the watershed;

Prepare outlet configurations for intermediate scenarios; and

Prepare final EIR/FSS.

Pond grading will be completed in accordance with Section 3.4 of the May 2013 North Oakville

EIR/FSS Terms of Reference document and the North Oakville Urban Stormwater Management

Ponds: Criteria & Design Guidelines Draft Revised: January 2012.

(ii) Monitoring Program Development

Because it is anticipated that the Town of Oakville and Conservation Halton will require that a monitoring

program be developed to demonstrate that the performance of the constructed pond is in compliance with

the approved design, WalterFedy proposes to prepare a monitoring program proposal consistent with the

program developed and implemented in support of the Glen Oak RDF in its current configuration.

WalterFedy proposes to revise the previous monitoring program to suit the proposed configuration.

(iii) Monitoring Program Implementation

It is anticipated that the Town of Oakville and Conservation Halton will require three years of monitoring

following full build out. The Town will require that the design engineer certify that the pond is functioning in

accordance with the original design, or develop an understanding of the differences that they find

acceptable. WalterFedy proposes to provide the monitoring services on an annual basis in accordance

with the following estimated effort:

Install monitoring equipment in the spring of each year (includes confined space entry);

Equipment Rental for the season including maintenance of the equipment (one velocity area

probe and flow triggered sampler at each inlet and outlet);

Conduct mid-season inspections (3);

Decommission monitoring equipment in the fall; and,

Prepare annual monitoring report and respond to comments.

4.1 Floodplain Delineation

The floodplain delineation line was also documented as part of the previously approved 2010 EIR/FSS and updated in the 2012 report. As the proposed development on the subject lands will not encroach into the floodplain as defined, this TOR and forthcoming EIR/FSS addendum report will not include any further work on floodplain analysis. The delineated Regional Storm floodplain will be included on site plan drawings along with the meanderbelt to illustrate that the draft plan limits do not encroach within either natural hazard area.



1415034-001

12

5.0 ECOLOGY

In terms of the ecological component to the EIR/FSS addendum, it has been confirmed that the

Provincially Significant Wetland (PSW) to the east of the subject lands, which forms part of the Oakville-

Milton West Wetland Complex, was staked on April 19th, 2011. The delineation and final buffer

surrounding this feature will be incorporated into the EIR/FSS addendum.

Typically, an EIR is carried out on a subcatchment basis, which forms the study area for the EIR as

described within the Town of Oakville’s ToR for the North Oakville EIR/FSS revised May 2013. The

previous approved Stantec EIR/FSS, which included the subject lands in review, comprised of the three

subwatersheds identified in the North Oakville Creeks Subwatershed Study (NOCSS), GO1116 (Glen Oak

Creek), SM1117a, and SM117.

The EIR addendum will address:

(i) The differences in land use and ecological function within the subject lands as compared to the

previous Stantec EIR/FSS;

(ii) Summary of the NSH for the areas adjacent to the subject lands; and,

(iii) Potential ecological impacts to the PSW located immediately adjacent to the subject lands as it

relates to the proposed development plan for the Oakville Green Health Sciences and Technology

District development plan.

The EIR addendum will also address Provincial Policies contained within the 2014 PPS which pertain to

development and site alteration on adjacent lands to natural heritage features and areas identified in

policies 2.1.4, 2.1.5, and 2.1.6 of the 2014 PPS.

5.1 Wetland Delineation

As part of the PSW staking which was completed in April of 2011, this TOR and forthcoming EIR/FSS

addendum report will not include further wetland delineation work as this was previously completed. Our

work proposes to stay outside of the PSW, therefore no further work will be conducted as part of our work.

The finalized survey limits for the PSW and 30 m buffer were overlaid on the land survey as prepared by

MMM Group dated July 9, 2015 submitted with the initial submission to the Town and Region on

September 18th, 2015.

6.0 CONCLUSIONS

This updated November 2016 TOR document serves to provide as a summary of the works and analysis

as contained in the updated and revised November 2016 EIR/FSS addendum for the subject lands. The

November 2016 TOR reflects all comments received to date from the Town, Region of Halton and

Conservation Halton.

As noted, the EIR/FSS addendum will serve as supplementary information to the already approved

EIR/FSS document for the new Oakville Hospital and District Energy sites.
