Water Environment Association of Ontario 2019 Annual Conference, Toronto, Ontario, April 16, 2019 by Robert J. Muir, M.A.Sc., P.Eng., Fabian Papa, MBA, P.Eng. Presentation reviews policies and regulations in Ontario promoting cost-effective infrastructure servicing. Summarizes the assessment of cost effectiveness of grey, green and blended green and grey flood damage reduction strategies on a system-wide basis. Identifies triple-bottom-line benefits of erosion mitigation reduction and water quality improvements due to green infrastructure implementation. Details of the analysis are presented in the proceedings paper also included here: https://www.cityfloodmap.com/2019/03/an-economic-analysis-of-green-v-grey.html The analysis indicates benefit cost ratios for flood control and other benefits and assesses funding impacts on stormwater utility fees in a case study in the City of Markham. Markham's current Flood Control Program consisting largely of grey infrastructure is shown to be cost-effective with benefits exceeding costs by 2 to 1 based on insured loss deferral (and a higher ratio considering higher total losses). Green infrastructure is shown to be less cost-effective at delivering flood control and the cost for achieving water quality benefits exceeds the estimated willingness to pay 'value' of those benefits. The analysis suggests that a critical, strategic evaluation of green infrastructure implementation targets is required prior to system-wide implementation, given cost concerns. ]]>

Green Infrastructure – Cost Effectiveness and Technical Challenges for Flood Mitigation, Robert J. Muir, M.A.Sc., P.Eng. Manager, Stormwater, City of Markham, January 30, 2018 - Mississauga, Ontario The presentation presents regulations and policies regarding cost effective infrastructure, explores green infrastructure capital costs in Ontario based on recent project tender costs and other North American extensive program sources, explores lifecycle cost (LCC) impacts of widespread green infrastructure implementation in Ontario, including cost per household and impacts on the current infrastructure deficit, and presents benefit cost analysis for city-wide grey and green infrastructure strategies including benefit/cost ratios for flood damage reduction. Unit costs of no regret programs such as sanitary downspout disconnection and plumbing isolation programs, and wastewater and stormwater system upgrades, and green infrastructure retrofits are presented per hectare. Gaps in research relying on meta-analysis estimates of flood control benefits that do not consider local engineering or costs are presented. Impacts of green infrastructure on wastewater systems and infiltration stresses is presented, and correlation of wastewater infiltration stresses with local sewer back-up risks is shown for the City of Markham. Water supply risks of green infrastructure relying on infiltration including chloride stresses are explored. The unfavourable benefit-cost profile of green infrastructure and potential impacts on wastewater system flood risks and municipal water supplies suggests a strategic review of implementation targets and policies is warranted to identify financially sustainable and technically-appropriate requirements.]]>

Unit costs of no regret programs such as sanitary downspout disconnection and plumbing isolation programs, and wastewater and stormwater system upgrades, and green infrastructure retrofits are presented per hectare. Gaps in research relying on meta-analysis estimates of flood control benefits that do not consider local engineering or costs are presented. Impacts of green infrastructure on wastewater systems and infiltration stresses is presented, and correlation of wastewater infiltration stresses with local sewer back-up risks is shown for the City of Markham. Water supply risks of green infrastructure relying on infiltration including chloride stresses are explored. The unfavourable benefit-cost profile of green infrastructure and potential impacts on wastewater system flood risks and municipal water supplies suggests a strategic review of implementation targets and policies is warranted to identify financially sustainable and technically-appropriate requirements.

Natural Environment Climate Change Summit, Extreme Weather Resiliency and Climate Adaptation Through Strategic Asset Management & Infrastructure Investments, Robert J. Muir, M.A.Sc., P.Eng., Manager, Stormwater, City of Markham, March 7, 2019, Ajax, Ontario The presentation explores the drivers for cost efficiency assessment infrastructure investments including those to mitigate flooding due to extreme weather and future climate change impacts on high intensity rainfall that contributes to urban flooding. Flood risk factors including severe rainfall trends are explored as well as hydrologic stresses due to urbanization and design standard evolution. Measures to reduce flooding in the City of Markham are explored using benefit cost analysis in the context of its comprehensive city-wide Flood Control Program. The program includes many projects that demonstrate a high return on investment (ROI) for flood risk reduction, making them eligible for Infrastructure Canada's Disaster Mitigation Adaptation Fund (DMAF) grant funding. An evaluation of risk management strategies is presented that includes traditional grey infrastructure engineering solutions such as sewer capacity upgrades, and emerging green infrastructure strategies including engineered and enhanced assets (e.g., bioswales, rain gardens, infiltration trenches, GSI). The strategies take a holistic, system-wide approach to evaluating benefits and lifecycle costs, including initial capital on on-going operation and maintenance costs. The analysis will be presented a t the annual Water Environment Association of Ontario conference in 2019 in Toronto, Ontario.

Green infrastructure, low impact development practices (LIDs), also called stormwater management best management practices (SWM BMPs), are often proposed to restore water balance functions and mitigate impacts or urbanization on runoff and recharge. One argument is that baseflows are lowered due to reduced infiltration and discharges to watercourses. It is a simple textbook theory. What does the data show? The following slide presentation was prepared to respond to the Ontario draft LID guidance manual in early 2017 since water balance impacts have been cited as justification for this infrastructure. Local studies show that baseflows have increased over decades of urbanization, calling into question the need for such measures considering that potential impact has not materialized. As noted in TRCA's Approved Updated Assessment Report under the Clean Water Act, at most gauges there was an upward trend in baseflows which prompted this: "These overall increases to baseflow volumes are contrary to the common thought that increased impervious cover leads to reduced baseflow" - so for those keeping score, data - one, common thought - zero. TMIG also analyzed baseflows in the GTA and noted “The seven-day average consecutive low flow data provides an indication of the observed baseflows within a watercourse, and hence is a suitable measure for determining whether baseflow trends exist in an urbanizing area. The trend analysis identified noticeable baseflow trends in 13 of the 24 recording stations. Of these eight urban and two rural stations exhibited an upward trend, suggesting increasing baseflow.”]]>

This presentation was made to the Southern Ontario Municipal Stormwater Discussion Group on September 27, 2018 in Brantford, Ontario. It describes benefit-cost analysis to show the return on investment (ROI) of infrastructure improvements to reduce flood damages (insured and total), and to achieve other benefits including erosion mitigation and water quality improvements. Earlier benefit cost analyses for projects ranging from the Winnipeg floodway to the Stratford, Ontario storm system master plan are shown. The benefit-cost ratio of an Ontario flood control study is shown including a comparison of grey and green infrastructure cost effectiveness - analysis shows the grey infrastructure solution can meet the current Disaster Mitigation Adaptation Fund (DMAF) benefit/cost threshold of 2:1 required to be eligible for federal funding. In addition, city-wide analysis of grey infrastructure storm and sanitary system upgrades and green infrastructure / low impact development infrastructure strategies is summarized. Results show that the grey infrastructure solution can meet the DMAF benefit/cost threshold of 2:1 but that the benefit/cost of green infrastructure is substantially below it considering flood reduction benefits. When other benefits are considered, and targeted implementation of green infrastructure is considered (e.g., representing 25% of the urban area with limited overland drainage design standards) and considering additional benefits including a substantial 'willingness to pay' estimate for water quality improvements, costs continue to exceed benefits. The insurance industry and some affiliated research groups have suggested that natural infrastructure or green infrastructure should be considered to improve climate resilience and reduce flood damages - this analysis would suggest that approach is misguided and could misdirect scare resources to ineffective strategies. ]]>

The insurance industry and some affiliated research groups have suggested that natural infrastructure or green infrastructure should be considered to improve climate resilience and reduce flood damages - this analysis would suggest that approach is misguided and could misdirect scare resources to ineffective strategies. ]]> Sun, 30 Sep 2018 14:26:44 GMT /slideshow/grey-and-green-infrastructure-benefit-cost-return-on-investment-analysis-for-flood-control-and-asset-management/117448736 RobertMuir3@slideshare.net(RobertMuir3) Grey and Green Infrastructure Benefit Cost, Return on Investment Analysis for Flood Control and Asset Management RobertMuir3 This presentation was made to the Southern Ontario Municipal Stormwater Discussion Group on September 27, 2018 in Brantford, Ontario. It describes benefit-cost analysis to show the return on investment (ROI) of infrastructure improvements to reduce flood damages (insured and total), and to achieve other benefits including erosion mitigation and water quality improvements. Earlier benefit cost analyses for projects ranging from the Winnipeg floodway to the Stratford, Ontario storm system master plan are shown. The benefit-cost ratio of an Ontario flood control study is shown including a comparison of grey and green infrastructure cost effectiveness - analysis shows the grey infrastructure solution can meet the current Disaster Mitigation Adaptation Fund (DMAF) benefit/cost threshold of 2:1 required to be eligible for federal funding. In addition, city-wide analysis of grey infrastructure storm and sanitary system upgrades and green infrastructure / low impact development infrastructure strategies is summarized.

Review of urban flood risk mapping methods to guide risk reduction strategies. Tiered vulnerability assessment for urban storm (overland pluvial and sewer), sanitary / wastewater and riverine systems is illustrated from "Flood Plain to Floor Drain", consistent with the author's design standards guideline for best practices and projects in existing communities. Example risk mapping / tiered vulnerability evaluations in Markham, Ontario and Stratford, Ontario are shown emphasizing where simple and intermediate risk assessment can guide no-regret, practically deployed policies and programs to reduce urban flood risk, and there advanced risk assessment can guide minor and major capital projects as part of more comprehensive studies in high risk areas that warrant infrastructure investments to lower flood damages in specific local systems. Presentation was made as part of the Ontario Urban Flooding Collaborative organized by Green Communities Canada. ]]>
