PROJECT INTRODUCTION 2 PURPOSE OF THE PROJECT The T own of East Gwillimbury is undertaking a T own-wide Water and Wastewater M aster Plan. The M aster Plan will identify long-term strategies for servicing the current and future populations, based on the projected growth for the T own to the year 2041. Problem Statement: The T own of East Gwillimbury is projected to experience significant population and employment growth over the next 25 years. As a result of this growth, a safe, e efficient, and r reliable source of water and wastewater services will become increasingly important and challenging. The Town’s water and wastewater systems will need to be expanded as necessary to accommodate this growth. M ASTER PLANNING PROCESS Complete a comprehensive review of background documentation, existing water and wastewater system and key relevant studies A M aster Plan is a l long term plan that provides a ‘roadmap’ of the water and wastewater infrastructure requirements based on the Identify opportunities and constraints to improve the water and existing and future growth projections to the year 2041. wastewater network based on existing and future populations. At the end of this study, the key deliverables will be: Calculate the future water and wastewater flows, and update the T own’s water and wastewater models 1. The completed M aster Plan Report documenting the preferred solution, process and analyses that were conducted. Develop alternative servicing solutions for future growth 2. A list of future infrastructure projects recommended for the T own to implement the M aster Plan, with high-level cost estimates and Evaluate the alternatives, using a set of criteria determined as part of the M aster Plan, to arrive at a preferred servicing solution timing. 3. A map indicating where these future infrastructure projects will be Prepare cost estimates and timing for recommended future located. infrastructure projects to implement the M aster Plan
WHY ARE WE CONDUCTING THIS REVIEW? 3 PLANNED GROWTH The T own is undertaking a review of the 2009 Water and Wastewater M aster Plan to accommodate the T own’s current and projected growth and to ensure that sufficient servicing can be provided to facilitate growth to 2041. Since the Y ork Region water and sewer networks form a backbone to the East Gwillimbury networks, this M aster Plan builds on Y ork Region’s M aster Plan. The current M aster Plan also reflects updates to provincial policy. The settlement areas such as Green Lane West, Holland Landing, Sharon, Queensville and M ount Albert are intended to accommodate the T own’s forecasted growth.

M UNICIP AL CLASS ENVIRONM ENTAL ASSESSM ENT 4 WHAT IS A M UNICIP AL CLASS EA The M unicipal Class Environmental Assessment (EA) was approved in 1990 under the Ontario Environmental Assessment Act as a way to streamline the planning of municipal infrastructure while managing environmental impacts, receive stakeholder and resident feedback, and ensure a transparent evaluation and decision process. The M unicipal Class EA Planning and Design process can include up to a total of 5 5 phases. The required phases to be completed are based on the type of study that is being conducted. At a minimum, a M aster Plan must follow the first 2 2 phases. Phases 3 through 5 are usually completed as part of a separate process when the time comes to implement the recommended infrastructure projects. The East Gwillimbury Water and Wastewater PIC #1 M aster Plan will be completed using Approach 1 of the Class EA M aster Planning process. This means that the study is We are here (PIC #2) conducted at a broad level and will result in a list of recommended infrastructure projects. Specific Class EA’s for Schedule B projects will be completed closer to the time of the project ’s implementation and after the M aster Plan is finalized.
SCREENING OF AL TERNATIVE SOLUTIONS 5 The alternative solutions have been screened based on the following : � Policy and Regulation Compatibility – Does the alternative comply with the Provincial and T own policies related to growth management and land development? � Does the Solution Address the Problem Statement - Alternatives that do not address the Problem Statement do not satisfy the M aster Plan’s core objective to support future growth to 2041. Future planning policies and opportunities to provide water and wastewater servicing for existing and future development would not be adhered to in selecting this alternative. 2. Water Efficiency / Conservation 1. Do Nothing The T own currently has a Water Conservation strategy that limits This alternative represents a scenario where no improvements or Outdoor Water Use (By-Law 2002-100). Implementation of expansions would be undertaken. This alternative does not comply further water conservation and reduction strategies to reduce with Provincial and T own policy related to growth. With the “Do water consumption may have marginal benefits. Water Nothing” alternative, municipal water and wastewater efficiency/conservation does not address future development infrastructure will be inadequate for future development. requirements Policy/regulation compatibility?

STUDY AREA 7 EXISTING WATER SYSTEM – CENTRAL GROWTH AREA Water projects outlined in the M aster Plan either address existing system deficiencies or are required due to growth. Within the Central Growth Area, three projects had alternative solutions which were assessed based on the criteria outlined on Board 6. Project alternatives are presented on B Board 9. Water Issue #1: Lower Fire Flows noted in the Queensville Sideroad/Sand Road Area Water Issue #2: There is currently only one watermain connection between the new Holland Landing subdivision and the existing system on Bradford Street
STUDY AREA 8 EXISTING WATER SYSTEM – M OUNT ALBERT The only water projects required within M ount Albert were due to growth. One of the projects in M ount Albert had alternative solutions which were assessed based on the criteria outlined on Board 6. Project alternatives are presented on B Board 10. Water Issue #3: Servicing required for the new development south west of M ount Albert Road and Ninth Line Y ork Region is currently carrying out an Environmental Assessment (EA) to investigate Water Quality in this area.
