Infrastructure Master Plan

The IMP project team is pleased to publish the As We Heard It (AWHI) report and Benefits to Existing (BTE) document.

This AWHI report embodies the project team's commitment to gathering, analyzing, and integrating comprehensive feedback from community groups, residents and industry experts. The report summarizes feedback from the June public engagement on the summary of the draft IMP.

We also share the draft Benefits to Existing (BTE) document, which explains the basis for attributing IMP project costs to existing ratepayers. The balance of project costs would be covered by the development industry.

Thank you to everyone who participated in the consultations on the Preliminary Policies and Program Recommendations of the Infrastructure Master Plan (May to July 2022). The IMP Team have reviewed and responded to the feedback received. The following document provides summaries of those comments:

As we heard it report

There will be another opportunity to provide feedback on the proposed IMP in late Spring 2023. More details will soon follow on Engage Ottawa!

The following are the project’s key milestones and anticipated dates:

• City of Ottawa Council adoption of New Official Plan ─ October 2021
• Ministry of Municipal Affairs and Housing Approval of New Official Plan – November 2022
• Infrastructure Master Plan Public Engagement Event ─ Q2 2023
• City of Ottawa Planning Committee to consider Infrastructure Master Plan ─ Q3 2023

The preliminary policies and program recommendations of the Infrastructure Master Plan (IMP) is now ready for review. The draft document includes detailed infrastructure-related policies that support the New Official Plan and provide clarification on City expectations related to infrastructure planning, approvals, and implementation. It also includes new program recommendations to support intensification.

Resident and stakeholder input regarding this document is being requested at this stage and will be taken into account as the City prepares the draft final IMP for consideration by City Council. If you have any comments or feedback on the document, please fill out the feedback form by July 22, 2022.

Development of the IMP is currently in progress, including several major components that address drinking water, wastewater, and stormwater management required to support the Official Plan objectives. The IMP will also enable associated greenfield and intensification development in urban areas and rural villages. A status update on key aspects of the plan and preliminary conclusions are provided below.

Intensification Capacity Management

The City is completing several studies to support the management of infrastructure capacity as intensification increases in existing neighbourhoods. These studies fall into the following three categories:

• Review of best practices in place in other major Canadian cities;
• Analysis of local water distribution and wastewater collection systems performance in existing neighbourhoods; and
• Review of strategic options for managing stormwater.

Through these studies, the following must be taken into consideration when developing the new IMP:

• Existing grading and development constraints limit opportunities to improve storm drainage system capacities;
• A regulatory mechanism will be required to enforce on-site stormwater management on virtually all intensification development projects where there is an increase in imperviousness. The proposed approach includes development of a design guide, sizing tables, approved servicing concept illustrations and standard drawings to simplify the design process for property owners;
• New City programs will be required to identify and prioritize upgrades to local water and sanitary systems based on intensification development pressure, asset condition, and existing system vulnerabilities; and
• A growth financing mechanism, such as Development Charges, will be needed to support these programs.

Early findings from these studies indicate that water and wastewater system capacity is available to support significant increases in intensification in most areas of the City. The key reasons for this are as follows:

• Per capita water demands have been dropping steadily over the last 30 years;
• Redevelopment in many areas of the City provides opportunities to remove wet weather flow from the sanitary sewer system; for example, through elimination of existing foundation drain connections;
• On-site stormwater management provides opportunities to reduce flows to the City’s combined sewers, allowing capacity for future sanitary flows;
• Local watermain sizing is not typically governed by average daily water demand;
• Pipe sizing standards govern the sizing of the upstream sections of local sanitary networks.

Water and Wastewater Master Plans

Studies to support updated Water and Wastewater Master Plans are in progress to identify the major infrastructure projects needed to support growth to 2046 and beyond. These major projects will account for land use intensification, greenfield development on vacant urban lands in established areas, and any urban expansion lands approved by Council in February 2021.

Detailed models of the existing water distribution system and wastewater collection system have been improved, updated, and calibrated based on monitoring data to support development of the Water and Wastewater Master Plans.

Gross City-wide projections were approved by Council in May 2021. Detailed local projections are currently being developed, which consider greenfield development and intensification-based development to support preparation of the plans.

Stormwater Master Plan

An updated Stormwater Master Plan (SMP) is also an important aspect of the IMP update. Generally, major stormwater infrastructure required to support greenfield development will continue to be planned and implemented by the development industry, subject to City approval processes. The Stormwater Master Plan will include recommendations for City-wide studies and programs, processes, and policies required to ensure resilience of Stormwater Management (SWM) systems and protection of receiving watercourses. It will also establish high-level requirements for stormwater management in expansion areas, including on sites with Low Impact Development (LID). LID involves the management and reduction of runoff as close to the site as possible to better mitigate impacts on receiving watercourses, compared to conventional approaches which treat stormwater at downstream locations.

The SMP will include an overview of existing and future conditions, including constraints and opportunities associated with existing infrastructure and natural drainage systems. Future conditions will consider local climate projections. The SMP also presents the strategy for developing stormwater management retrofit plans in existing development areas.

Rural Servicing

Expansion to the City’s village boundaries are not being contemplated in the New Official Plan. As such, it is not anticipated that any new infrastructure projects to support village growth will be identified in the IMP. However, the IMP will provide a status report on village development and the supporting infrastructure projects that were identified in previous editions of the IMP. Private servicing issues in the rural area will also be reviewed.

The Infrastructure Master Plan Update includes:

• Affordability lens – cost-effective infrastructure
• Resiliency lens – potential impacts associated with climate change and system failure conditions.
• Actions supporting infrastructure policies in the new Official Plan
• Descriptions of infrastructure systems and planning programs

The anticipated outcomes are:

• Recommended water and wastewater infrastructure projects needed to provide service to 2046
• Future system performance
• Cost estimates and funding sources for each project
• Approximate year of implementation

The IMP update is supported by several technical studies. The studies will:

• analyze the performance of the water and wastewater infrastructure under the full range of potential operating conditions, today and in the future;
• review and update system design criteria;
• develop strategies to adapt to the impacts of climate change;
• assess the servicing requirements created by suburban growth and intensification, including new high-density development around rapid transit stations;
• identify growth-related water and wastewater projects and cost estimates;
• consider opportunities to coordinate rehabilitation of existing infrastructure in the central area with planned projects, to save money and limit disruption to the public;
• examine the options available to support safe and cost-effective village growth;
• identify high level stormwater management concepts, criteria and study requirements for growth areas to support system resiliency; and
• evaluate and document opportunities for stormwater retrofit in existing areas, and Low Impact Development measures in growth areas to mitigate development impacts on City watercourses.
