Urbanization and Baseflow Impacts - Evidence-based Water Budget Management an...Robert Muir
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.”
IDF Trend Analysis, Future Climate Projections & System Design for Extreme We...Robert Muir
Presentation on policies promoting climate resilience in Ontario, a review of insurance industry and government agency statements on extreme weather trends, a review of national and local engineering climate datasets annual maximum series and derived IDF trends, particularly southern Ontario. A review of engineering and academic studies for multiple municipalities highlights many unsupported claims on extreme weather trends. Practical design approaches given decreasing or stationary IDF trends, and allowances for future climate changes effects are noted, including the consideration of design stress test analysis with synthetic hyetographs or rain intensity increases. Design hyetographs are shown to be more critical to infrastructure system design than IDF curve shifts in regions such as Southern Ontario.

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.

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.

A case for change transforming solid waste mangement in nova scotiaGord Helm
The Premier identified Nova Scotian's need to embrace positive change. The Provincial and Federal governments are looking to address climate change. Municipalities and businesses are struggling with unsustainable solid waste management costs. The advanced waste conversion technology - enhanced plasma gasification - offers an answer to all of these issues.
CH2M Hill, environmental Engineering firm, presents "Value of an Integrated Planning Approach for Euclid." For the City of Euclid sewer utility, an Integrated Planning approach can address EPA stormwater issues with economic, environmental, and social benefits.
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.
Grey and Green Infrastructure Benefit Cost, Return on Investment Analysis for...Robert Muir
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.

An Economic Analysis of Green v. Grey InfrastructureRobert Muir
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.

6th Annual Low Cost Produced Water Management Marcellus & Uticamarketinglbcg
Despite Marcellus and Utica production bulking up, many operators in the Golden Triangle have gone from high level of activity to extremely low level of activity,with everyone asking the question: What do we do with all this water?
The industry has become highly efficient at recycling 100% of its produced water, butwith operators having consolidated their frac jobs, the burning questions now are :
What are the most cost-effective advanced treatment technologies that can handle fluctuating production rates? What are the producer's selection criteria? What is the overall cost of treating water would be with each system?
Can Marcellus' produced water be used on Utica wells? Is there formation compatibility?
How can injection wells be constructed and operated while ensuring seismic events are mitigated?
How can E&Ps coordinate frac jobs and put infrastructure in place to make water sharing a reality and deliver significant cost savings?
Ultimately, how do we manage this produced water going forward in a low cost environment?
The 6th Annual Low Cost Produced Water Management: Marcellus And Utica 2016, answers each of these questions and more with an industry approved agenda and supported speaker line-up, delivering tangible learning benefits to the minimize the cost per barrel and maintain operations in a low cost environment.

UNDERSTANDING WHAT GREEN WASHING IS!.pdfJulietMogola
Many companies today use green washing to lure the public into thinking they are conserving the environment but in real sense they are doing more harm. There have been such several cases from very big companies here in Kenya and also globally. This ranges from various sectors from manufacturing and goes to consumer products.

Characterization and the Kinetics of drying at the drying oven and with micro...Open Access Research Paper
The objective of this work is to contribute to valorization de Nephelium lappaceum by the characterization of kinetics of drying of seeds of Nephelium lappaceum. The seeds were dehydrated until a constant mass respectively in a drying oven and a microwawe oven. The temperatures and the powers of drying are respectively: 50, 60 and 70°C and 140, 280 and 420 W. The results show that the curves of drying of seeds of Nephelium lappaceum do not present a phase of constant kinetics. The coefficients of diffusion vary between 2.09.10-8 to 2.98. 10-8m-2/s in the interval of 50°C at 70°C and between 4.83×10-07 at 9.04×10-07 m-8/s for the powers going of 140 W with 420 W the relation between Arrhenius and a value of energy of activation of 16.49 kJ. mol-1 expressed the effect of the temperature on effective diffusivity.

2. The New Orleans Hurricane Protection System: What Went Wrong and
Why-- 10 Lessons Learned from Katrina by the ASCE Hurricane Katrina
External Review Panel and the USACE Interagency Performance Evaluation
Task Force
1. Failure to think globally and act locally-We must account for climate
change
2. Failure to absorb new knowledge
3. Failure to understand, manage, and communicate risk-Need to take
rigorous risk based approach,
4. Failure to build quality in
5. Failure to build in resilience
6. Failure to provide redundancy
7. Failure to see that the sum of many parts does not equal a system
8. The buck couldn’t find a place to stop--Poor organization, lack of
accountability
9. Beware of interfaces: materials and jurisdiction
10. Follow the money-People responsible for design and construction had no
control of the monies.
3. Contentious issues require a commitment to
listen carefully and work together for solutions
to be effective
4. Trust, Legitimacy and Relevance of
Science
• Building trust can be
accomplished by developing
partnerships within local
governments and
stakeholders
• Through participation and
familiarity in the process
people will facilitate a deeper
trust in science products.
7. Regulatory Drivers
• Consent decrees and Long term control plans for CSO
separation
• NPDES MS4 Phase I and Phase II has been largely an
issue of due diligence with respect to SWMP
• TMDLs are based on WQ standards—due diligence
does not matter
• 80% TSS Removal will not meet “no net increase
standard”
• GI and LID will be needed to meet TMDL requirements
8. In the News…..
What is difference between these outcomes?
Negotiated plans using Green Infrastructure to
reduce reliance on Gray Infrastructure
12. • The environmental and water quality
benefits of LID are well established,
• There are considerable economic,
infrastructure, and adaptation
planning benefits that are NOT WELL
KNOWN from using LID-based
strategies.
Benefits of LID and Green
Infrastructure
14. Not All Costs are Equal
When implementing stormwater
improvements, it is important to consider:
who pays, how, and when.
1. Existing municipal programs and long-term
bonds
2. Stormwater Utilities—fees upon amount of
SW generated
3. Developer, Owner, Consumer

19. A Low Impact Development
Approach at Greenland
Meadows
Greenland, New Hampshire
Utilizing an LID approach that featured acres of
porous asphalt and a gravel wetland, a cost-
competitive drainage system was designed for a
large retail development. The total impervious
area of the development – mainly from rooftops
and non-porous parking areas – is approximately
25.6 acres. This project had an estimated 26%
cost reduction due to cost avoidance in
associated drainage infrastructure (ponds and
piping) with the use of Low Impact Development.

• The original cost estimate using gray
infrastructure was $144 million (2009
dollars).
• Gray-Green design including a total of
$11 million allocated for green solutions,
the cost estimate for this integrated
approach was $81 million.
• A savings of $63 million for the city

Scenarios
• GI will provided
a 22% reduction
in LTCP capital
cost
• Funds for labor,
supplies, and
equipment
• Replacing
energy
demands of
grey
infrastructure
O&M burden shifts to people in
replace of heavy energy
demand
26. Economic Conclusions
• Green Infrastructure is being embraced nationally due to reduced demand
on gray infrastructure
• GI has value for social and economic in addition to environmental
• LID may add expense on a per item basis
• Project cost reductions were observed from 6% in residential developments
to as high as 26% in commercial projects.
• Municipal use of GI reported cost reductions of 21% to as high as 44%.
• Benefits extend to municipal, private, and commercial entities
• Transfer of monies from infrastructure to jobs associated with the
maintenance activities.
• From a sustainability perspective, a range of benefits includes reductions in
flood damage and increased resiliency of drainage infrastructure;
• Reductions of 33 to 50% in energy demands for heating and cooling.
• A 50% reduction in time to sale, and increased property values of 12-16%.
• Other benefits were incentives in the form of rebates, cost-sharing, and tax
credits. IE. Impervious cover charge
26
28. WHY DO WE CARE?
• System performance
determines the degree and
intensity of usage of a
technology, and influence the
cost of implementation
• Municipalities will be
developing implementation
plans for managing nutrients
• Improvements in performance
could result in reduced cost of
implementation
29. Design and Performance
Not all bioretention systems function equally
• There is a tremendous
amount of variety within
design specifications and
resulting performance that is
not well understood
• Bioretention systems vary
widely with respect to design
features

43. Commercial Street
Reconstruction Porous
Pavement
Provincetown, Massachusetts
In 2012 Provincetown began the installation of
over 5,000’ of the first “Porous Municipal Main
Street”. The project addressed existing
infrastructure problems with flooding and
drainage along a main thoroughfare that has
tremendous traffic during the busy tourist
season. A high durability asphalt mix-design
was chosen to meet the commercial traffic
requirements. Through the use of widespread
infiltration, the design seeks to manage
stormwater and beach impairments which
occur from the discharge of untreated runoff
from many outfalls. Beach closures at these
outfalls were eliminated in 2013 and numbered
18 in 2011, and 9 in 2012.
44. Provincetown
• Harbor is listed on the 2010 Integrated List of
Waters as a “Category 4a” water body – TMDL for
