Watershed scale[edit]

These tools might assist in proposing policies and management programs focusing on conservation and preservation; effect of land use on environmental resources.

  • Municipal stormwater risk management framework

Sourcewater protection water quality risk assessment for climate change[edit]

This project is to develop a science-based handbook for the assessment of source water quality vulnerabilities to climate change. The handbook will assist Source Water Protection Committees with the preparation of Climate Change adaptation policies to address the relevant climate change impacts associated with their source protection areas. The handbook will include guidance and worksheets for carrying out climate change vulnerability assessment in order to incorporate relevant broad scale indicators into the drinking source water vulnerability scoring assessment.

  • Westhoff water balance model
  • Wetland hydrologic analysis tool

Subwatershed scale[edit]

These tools help assess the effect of land use scenarios and urban stormwater practices on different objectives of water balance, stream erosion, water quality , temperature, baseflow, flooding, fisheries, aquatic life. They may assist in choosing preferred strategies based on public acceptance, cost, technical feasibility, ability to meet goals and objectives, potential to enhance environmental impact of strategy on future land uses.

Macroeconomic study[edit]

This project (due 2020) will develop, test and deliver a first-ever methodology and model employing an "Equitable Responsibility" approach for transformational stormwater design. The user-driven model will enable detailed analysis and cross-analysis of multiple parameters for stormwater management (SWM), hydrologic function and cost-benefit comparisons applying scale and infrastructure aggregation, integration and distribution, and climate change scenarios to achieve optimal system performance for mitigation of risks (e.g., flooding, drought, erosion, source water contamination, etc) associated increasing frequency and severity of extreme weather. The methodology and model will also provide for the development of a municipal-cost sharing or equitable responsibility mechanism for drainage basin-scale (and larger scale) SWM systems.

Risk and return and investment tool[edit]

A Tool for water infrastructure that will help municipalities and conservation authorities make evidence-based cost-effective decisions to reduce flood risk. The Tool will perform the following key functions:

  • Fully assess baseline flood risk and quantify the potential impact
  • Evaluate overall risk-reduction that can be achieved by various management options
  • Perform a financial assessment of the return on investment associated with each management option, by comparing life cycle costs to the costs mitigated by reducing flood risk.

Thermal stream index[edit]

  • Hotspot identification tool-sediment
  • Natural assets project

Environmental impact report/ subdivision plan scale[edit]

If your seeking to summarize findings of watershed, subwatershed plans and done on a tributary subcatchment boundary.

Integrated water management tool[edit]

This tool helps to build a strong business case within a sustainability framework (environmental, economic, social) for implementing connected and spatially intensive green infrastructure that can reduce the impacts of stormwater flows (e.g. overland runoff, erosion, and water quality) and provide associated co-benefits to the community. The tool can consider future land use change/ climate change scenarios. The IWM tool can be used to model and determine GI types, sizing and intensity of application at a site/ neighbourhood level to meet SWM criteria while considering the cost and co-benefits of the design. This tool can be used to determine GI opportunities on priority sites identified by the Risk and Return on Investment Tool.

Soil risk assessment tool[edit]

The Soil Risk Assessment (SRA) Tool has been created to predict average annual soil loss from areas which have implemented a variety of ESC measures. The SRA tool can be used to assess the efficiency of ESCs on construction sites and to determine areas of high erosion risk.

Wetland water balance module: Visual Otthymo 5[edit]

Stormwater management planning[edit]

Topsoil and soil amendment calculator[edit]

This best practices guide is intended to provide both the rationale and practical guidance needed to improve conventional urban construction soil management practices in Ontario. It is a useful resource to designers and engineers involved in urban and landscape design, government agencies involved in the permitting and inspection of urban construction projects and contractors involved in urban construction and landscaping.

Post construction maintenance or monitoring[edit]

  • Green infrastructure asset management tool
  • SWM facilities maintenance tracking status asset management tool

Online training modules[edit]
