1. Definitions
Climate Bonds Initiative (CBI): An investor-focused not-for-profit organisation, promoting large-scale investmentsthat will deliver a global low carbon and climate resilient economy. The Initiative seeks to develop mechanisms tobetter align the interests of investors, industry and government so as to catalyse investments at a speed and scalesufficient to avoid dangerous climate change.
Climate Bond: A climate bond is a bond used to finance – or re-finance - projects needed to address climate. They
range from wind farms and solar and hydropower plants, to rail transport and building sea walls in cities threatened
by rising sea levels. Only a small portion of these bonds have actually been labelled as green or climate bonds by
their issuers.
Certified Climate Bond: A Climate Bond that is certified by the Climate Bonds Standard Board as meeting therequirements of the Climate Bonds Standard, as attested through independent verification.
Climate Bonds Standard (CBS): A screening tool for investors and governments that allows them to identify green
bonds where they can be confident that the funds are being used to deliver climate change solutions. This may bethrough climate mitigation impact and/ or climate adaptation or resilience. The CBS is made up of two parts: theparent standard (Climate Bonds Standard 2.1) and a suite of sector specific eligibility requirements. The parent
standard covers the certification process and pre- and post-issuance requirements for all certified bonds, regardlessof the nature of the capital projects. The Sector Criteria detail specific requirements for assets identified as fallingunder that specific sector. The latest version of the CBS is published on the Climate Bonds Initiative website
Climate Bonds Standard Board (CBSB): A board of independent members that collectively represents $34 trillion ofassets under management. The CBSB is responsible for approving i) Revisions to the Climate Bond Standard,
including the adoption of additional sector Criteria, ii) Approved verifiers, and iii) Applications for Certification of abond under the Climate Bonds Standard. The CBSB is constituted, appointed and supported in line with thegovernance arrangements and processes as published on the Climate Bonds Initiative website.
Climate Bond Certification: allows the issuer to use the Climate Bond Certification Mark in relation to that bond.
Climate Bond Certification is provided once the independent Climate Bonds Standard Board is satisfied the bondconforms with the Climate Bonds Standard.
Green Bond: A Green Bond is one in which proceeds are allocated to environmental projects. The term generally
refers to bonds that have been marketed as “Green”. In theory, Green Bonds proceeds could be used for a wide
variety of environmental projects, but in practice they have mostly been the same as Climate Bonds, with proceeds
going to climate change projects.
Technical Working Group (TWG): A group of key experts from academia, international agencies, industry and NGOs
convened by the Climate Bonds Initiative. The TWG develops Sector-Specific Criteria - detailed technical criteria forthe eligibility of projects and assets as well as guidance on the tracking of eligibility status during the term of thebond. Their draft recommendations are refined through engagement with finance industry experts in convened
Industry Working Groups and through public consultation. Final approval of Sector Criteria is given by the CBSB.
Water Assets: Engineered, nature-based and hybrid water infrastructure for the purposes of water collection,
storage, treatment or distribution, or for flood protection or drought resilience.

2. Introduction
2.1. Purpose & use of the document
The Water Infrastructure Criteria of the Climate Bonds Standard are intended to provide transparent, verifiable,science-based Criteria for screening water infrastructure projects proposed for inclusion under a Certified Climate
Bond. They enable issuers to participate in the certified green bond market, and investors to be confident that theirinvestment is being used for climate-compatible water infrastructure projects.
The Water Infrastructure Criteria themselves are detailed in the full Water Infrastructure Criteria document. That
document details the scope of water infrastructure assets and projects eligible for inclusion in a use-of-proceeds
Certified Climate Bond, and the conditions of that eligibility. Those conditions may include the conduct of a
Mitigation Assessment and/ or and Adaptation and Resilience Assessment. Readers are directed to that document,
available at http://www.climatebonds.net/standard/water, for full information on when such Assessments are neededin respect of water infrastructure projects, and how eligibility is thereby assessed and determined.
This document is a supplementary note to the Water Infrastructure Criteria, to be read and used in conjunction withthem. It provides supplementary guidance for conducting Mitigation and Adaptation & Resilience assessments under
the Criteria.

2.2. Contents of this document
Applying the Water Infrastructure Criteria of the Climate Bonds Standard requires evaluating proposed projects’
climate mitigation impacts, and their ability to address and contribute to aspects of climate adaptation and resilience.
The former is evaluated via a Mitigation Assessment. Section 4 includes specific guidance on this.
The latter is evaluated via an assessment of the Vulnerability Assessment and Adaptation Plan prepared by the issuer.
This assessment is based on a scorecard methodology, comprising a series of binary questions. In Section 5, each ofthese questions are reviewed in turn, to help you better interpret what each one means and what materials areneeded to evaluate compliance. A brief description of the documentation needed is given, as well as a relevant
example for illustrative purposes. Many of the examples used in this guide come from a recent bond scoring the
public utility the San Francisco Public Utilities Commission, and are tailored more to public utility bonds, but the
Guide is intended to be applicable in a variety of contexts.
In addition, Section 5 provides general guidance applicable to conducting both Mitigation and Adaptation andResilience Assessments.

3. General Guidance
Readers of this Guidance Note are reminded that all bonds certified under the Climate Bond Standard must also
comply with the common requirements set for all certified bonds, as well as sector-specific Criteria. These common
requirements are contained in the Parent Standard 2.1. See Standards webpage for this.
More specifically to water infrastructure related bonds, it is also highlighted that the CBI expects that any bondissuing entity seeking certification under the Water Infrastructure Criteria is aware of and in compliance withacceptable guidelines or existing standards related to social and human rights and broader environmental
considerations in the context of water development. Appendix 2 of the Water Infrastructure Criteria document lists
key best practice guidelines in this regard.
In addition, the following clarification points apply more specifically to both the conduct of the Mitigation Assessment
and the Adaptation & Resilience Assessment.

3.1.1. Building on existing references and information sources
Climate mitigation — greenhouse gas accounting — has been well understood by the finance sector for some time,and Mitigation Assessment represents a widespread and well-understood process for the finance and verifiercommunities, and the methodology described here should be familiar.
Terms such as Vulnerability Assessment and Adaptation Plan are much less well understood or appreciated byfinance audiences, but they have been standard practice in water management, infrastructure design and planning,
and reoperation and evaluations systems globally for some years. The best practice for most long-lived infrastructure
investments has increasingly included evaluating climate risks (Vulnerability Assessment) and preparing contingencies
to address those risks (Adaptation Plan), particularly for water-related investments. Many institutions have alreadyswitched to mandatory climate risk reports or “climate proofing” procedures, and climate adaptation and risk
assessment staff are widespread and common. They are not unusual or exotic processes or types of documents torequest. For instance, the City of San Francisco, California, requires climate risk assessments for all infrastructure
investments and allocates support staff to this process.
Supporting documentation for the San Francisco example given includes documents produced by the California
Department of Water Resources, State Water Resources Control Board, the U.S. Environmental Protection Agency,
and the U.S. Geological Survey. Nearly all of the examples used in this guide were accessed electronically, and links
are provided where available. And reaching out to personnel to these types of agencies (and the staff in your own
organization that interacts with them) can aid immensely in the completion of this assessment.
Because the Adaptation and Resilience Assessment in particular will likely require input from multiple municipal
departments, this Guidance is also aimed at connecting investors, underwriters, and auditors to their counterparts inlegal, engineering, and environmental compliance – this will be essential in gathering the necessary information tocomplete the Assessment. In many, if not all cases, the documentation and evidence required will already exist within
the issuing organization or be publicly available.

3.1.2. Project boundaries
When describing projects that are fully new, the project boundaries should be clear. But for expansions ormodifications to existing facilities, the lines may be harder to define. For this, the following guidelines are given:•••

If a utility is upgrading or modifying an existing facility, in general, the evaluation should be limited to the useof proceeds, rather than the whole facility being considered and scored.
If some components for the modification to an existing facility have a longer operational lifetime than theoverall facility, the latter’s operational lifetime should be the standard of judgment.
For projects that depend on other systems (e.g., electricity supplied by other institutions), the “project”
should only include the investment at hand.

4. Conducting a Mitigation Assessment
The Mitigation Component of the Water Infrastructure Criteria is intended to provide transparency over the impactthat the use of proceeds will have on GHG emissions, and the degree of mitigation delivered over the operational
lifetime of the project or asset.
Where no emissions impact is expected, the issuer must disclose the justification for this finding and provide
supporting documentation. This might include circumstances where the investment would not be expected to impact
on energy usage, for example.
Where emissions impact is expected, the issuer is required to estimate the GHG mitigation impact that will bedelivered over the operational lifetime of the project or asset. This impact should be defined in terms of thedecreased emissions or increased sequestration relative to a business as usual baseline.

4.1. Information to be provided by the issuer
The issuer must describe:• The calculations and assumptions used to arrive at an emissions baseline;• Projected emissions over the life of the project and associated estimated GHG mitigation impact comparedto that baseline;• A credible, independently verifiable, method of tracking actual emissions and mitigation impact over the lifeof the bond.

4.2. Assessment Integrity
Both baseline and projected project emissions are theoretical constructs that contain a significant degree of
uncertainty. As such, the assumptions, values and procedures used in the mitigation assessment must be
conservative to ensure that the GHG emission reductions or removals are not over-estimated.

4.3. Acceptable methodologies for determining baselines and estimated performance against
those baselines
The baseline proposed by the issuer may be ‘business-as-usual’ emissions. Or, in the case of a new asset, it may be a
performance standard baseline. For example, CDM Modalities & Procedures allow for the use of performancestandards to determine baselines, e.g. a baseline may be derived as “The average emissions of similar project
activities undertaken in the previous five years, in similar social, economic, environmental and technologicalcircumstances, and whose performance is among the top 20 per cent of their category” (para. 48 of the CDM
Modalities & Procedures at http://www.cdmrulebook.org/337.html).
Baselines will vary depending on infrastructure type and all of the methodologies discussed in this section haveinfrastructure-specific guidelines for baseline emissions calculation.
Baselines can be determined using credible methodologies such as (but not limited to):• The UNFCCC’s Clean Development Mechanism (CDM),• Climate Action Reserve,• American Carbon Registry• National and state / provincial approaches or any other credible, robust methodology.

GUIDANCE NOTE TO ISSUERS AND VERIFIERS: SUPPLEMENTARY NOTE TO THE WATER INFRASTRUCTURE CRITERIA

Below are brief descriptions and links to four different GHG mitigation methodologies that the issuer may wish to use
for the mitigation assessment.
• In the United States, the American Carbon Registry (ACR), developed by Winrock International, publishes
standards, methodologies, protocols and tools for greenhouse gas (GHG) accounting, which are all based on
International Standards Organization (ISO) 14064 and are routinely reviewed to ensure they reflect soundscientific practice. Proposed water climate bond projects with a wetland restoration component, for example,
could use their Wetland Restoration Methodology Framework module:
http://americancarbonregistry.org/carbon-accounting/standards-methodologies/restoration-of-degradeddeltaic-wetlands-of-the-mississippi-delta/wr-mf-wl_v2-0.pdf. Projects related to low-GHG emitting water
purification systems could use the following methodology: http://americancarbonregistry.org/carbonaccounting/standards-methodologies/low-greenhouse-gas-emitting-safe-drinking-water-productionsystems. General information about the ACR can be found here: http://americancarbonregistry.org/carbonaccounting• In Australia, the Emissions Reduction Fund issues Australian Carbon Credit Units (ACCUs) for emissions
reductions and publishes its own methodology criteria, developed by the government’s Department ofEnvironment and Energy. For information on the approved methodologies for calculating baseline emissions,see the Australian Department of Environment and Energy’s sector-specific guidelines here:
http://www.environment.gov.au/climate-change/emissions-reduction-fund/methods.
• In the United Kingdom, the UK Water Industry Research (UKWIR) team uses its Carbon Accounting
Workbook (CAW) to provide UK water companies with a uniform and transparent approach for GHG
emissions accounting that is in line with both the UK Department of Environment Food and Rural Affairs(Defra) Guidelines and Carbon Reporting Commitment (CRC) requirements. The tool itself is not publicly
available, but more information for UK companies is available here: https://www.ukwir.org/reports/15-CL-0122/129644/Workbook-for-Estimating-Operational-GHG-Emissions-Version-9.
• For countries without national mitigation standards, the UNFCCC’s Clean Development Mechanism (CDM)
provides an accredited system for validating, registering, and monitoring GHG mitigation projects. All
potential projects must be validated by a third party agency and approved by the CDM Executive Board. All
baseline methodologies currently approved by the CDM Executive Board are listed on their website:
https://cdm.unfccc.int/methodologies/standard_base/index.html. Approved CDM methodologies ofparticular interest to the water sector include (but are not limited to):o Energy efficiency and fuel switching measures for industrial facilities:
https://cdm.unfccc.int/methodologies/DB/M4LINVAO7Y1OZBCUWFBVZBXT3546LM
o Methane recovery in wastewater treatment:
https://cdm.unfccc.int/methodologies/DB/5JGU2EUK716KG3UAE2HBVCK16K199K
o Switch from non-renewable biomass for thermal applications by the user:
https://cdm.unfccc.int/methodologies/DB/9LFOR81TCT5FLI1AJYP46CQY8O2J79
o Methane avoidance through separation of solids from wastewater or manure treatment systems:
https://cdm.unfccc.int/methodologies/DB/694L0HKMRM81GWPI2HU0MZBHNHSXYBo Methane emission reduction by adjusted water management practice in rice cultivation:
https://cdm.unfccc.int/methodologies/DB/D14KAKRJEW4OTHEA4YJICOHM26M6BM
Not all GHG reporting methodologies are equally robust; however, most credible GHG reporting programs stem fromthe World Resources Institute and World Business Council on Sustainable Development’s Greenhouse Gas Protocol,
which set the global standard for measuring, managing, and reporting GHG emissions. Therefore, using amethodology which is in compliance with the WRI/WBCSD GHG Protocol is strongly recommended. Information on
this Protocol is available at http://www.ghgprotocol.org/about-ghgp/about-wri-and-wbcsd

5. Conducting an Adaptation & Resilience Assessment
As noted above, the Adaptation and Resilience Component of the Water Infrastructure Criteria consists of anevaluation of the efficacy and thoroughness of the issuer’s Vulnerability Assessment and Adaptation Plan.
What are these documents?
• The Vulnerability Assessment is the document, or series of documents, which both describes the methods
and process used to analyze vulnerability and diagnoses and itemizes any relevant climate risks and impacts
that have been seen to date and that may emerge over the project’s operational lifetime; and• The Adaptation Plan is the document, or series of documents, that collectively constitute a risk management
plan that refers directly to the Vulnerability Assessment, describing responses to address the climate impacts
described in the Vulnerability Assessment. How will these risks be reduced or avoided? Has the project been
made more robust, or will the management plan need to be reevaluated in several years?
• They are therefore paired ‘documents’.
These two documents need not be long. For the purposes of evaluation under the Water Infrastructure Criteria of the
Climate Bonds Standard, the issuer’s Vulnerability Assessment and Adaptation Plan documents may be usefullysummarized into a short document, particularly if the relevant material comes from a number of subsidiary
documents. However, a summary document is not mandated by the standard.
Where will you find them?
In most cases, the issuer institution will have formal processes for evaluating and addressing climate impacts, but acommunication or awareness gap may exist within institutions between finance and design or planning teams.
Within larger organisations, these documents are often prepared by technical, environmental, or engineering
departments — who use them as the basis for developing designs, long-term planning, and defining operating rules.
For some organizations (especially for cities), an environment department or agency may be tasked with creatingurban or regional Vulnerability Assessments and Adaptation Plans. In some cases, a very specific assessment and plan
may be prepared that applies directly to the use of proceeds.
The evidence used to explain or justify particular scores described below may be more complex or technical than the
narrative vulnerability assessment and adaptation plan, hence it might come from a mix of sources from a mix ofdepartments and institutions.
Who should carry out the assessment?
It is recommended that the issuer should first self-score their Vulnerability Assessment and Adaptation Plan, including
gathering the supporting documentation for the scores proposed, and pass this to the verifier. The verifier will thenhave the relevant information to carry out their own review of the issuer’s Vulnerability Assessment and Adaptation
Plan and the provisional scorecard completed by the issuer.
How to carry out the assessment?
The Water Infrastructure Criteria requires the evaluation of the scope and coverage of the issuer’s Vulnerability
Assessment and Adaptation Plan using a scorecard methodology. The scorecard lists a series of binary questions. The
overall score for each section of the scorecard determines whether the project is eligible for certification per theterms of the Adaptation and Resilience Components of the Water Infrastructure Criteria.
Further information on the scoring thresholds used to determine whether overall the completed scorecard meets theeligibility requirements of the Adaptation & Resilience component of the Water Infrastructure Criteria is given in the
Water Infrastructure Criteria document available at http://www.climatebonds.net/standard/water.

What supporting evidence is required?
For each question, “evidence” of analysis / research, or “disclosure” of the relevant regulatory, governance, or legal
documents is required.
For example, allocation question #3 asks, “Is there a distinction between the allocation regimes used in “normal”
times and in times of “extreme/ severe” water shortage?” Evidence to document this could be an urban water planthat lays out adjusted water allocation schedules planned under a variety of climate scenarios. Disclosure might be alink to relevant regulations or statutes in the state or national water code that mandates allocation adjustments
during times of extended or extreme water shortage.
Further examples are incorporated in this document for your reference.

5.1. Working through the Scorecard
The first three parts of the scorecard evaluate the issuers’ Vulnerability Assessment. These three parts are: Allocation,
Governance, and Diagnostic Assessment. Each part consists of a number of associated questions.
•••

Part 1: Allocation addresses how water is shared by users within a given basin or aquifer. With regard to the
proposed bond project, this element of the scorecard concentrates on the potential impact(s) of bondproceeds on water allocation. This is important in the context of climate adaptation as future uncertainty
regarding water supply may impact allocation amounts over time and it is important for any bond projects totake water allocation mechanisms into account.
Part 2: Governance addresses how / whether the use of proceeds takes into account the ways in which water
will be formally shared, negotiated, and governed. Strong water governance is important in ensuring
compliance with allocation mechanisms and helps protect water resources from conflict, overuse, waste, anddegradation.
Part 3: Diagnostic Assessment addresses how / whether the use of proceeds takes into account changes tothe hydrologic system over time. Is the project infrastructure and / or ecosystem resilient to current andprojected climate change impacts on water resources within the basin? For this element, the use of acredible hydrologic model is essential to understanding current and future conditions within the watershed
or aquifer in question.

Sections 5.1.1 to 5.1.3 go through each question in turn across these three parts respectively, providing guidance on
how each question should be interpreted, and the specific nature of evidence required and potential sources for that
information.
The fourth part of the Scorecard includes 5 questions to assess the Adaptation Plan (were one needed). Section 5.1.4
goes through each of these questions in turn, providing guidance on how each question should be interpreted, andthe specific nature of evidence required and potential sources for that information.

5.1.1. Section I of the Scorecard: ALLOCATION Scoring Guide
The first section of the Scorecard deals with how the Vulnerability Assessment addresses water allocation andregulation within the relevant basin or aquifer. Water allocation mechanisms are usually set by the state or local
water regulatory agency.
In the United States, much of this information is now available online, but reaching to agency staff may also be
helpful in collecting evidence / disclosure information.

GUIDANCE NOTE TO ISSUERS AND VERIFIERS: SUPPLEMENTARY NOTE TO THE WATER INFRASTRUCTURE CRITERIAQuestion 1.1: Are there accountability mechanisms in place for the management of water allocation thatare effective at a sub-basin and/or basin scale?
Scoring: 1 if yes, 0 if no, n/a if not applicable
Evidence or Disclosure: Disclosure
What this means: In order to score 1 on this question, there must be water allocation verification or compliancemechanisms in place not only at the project or municipal level, but at the relevant hydrologic scale (for surface water:
the river basin or sub-basin, for groundwater: the aquifer). Sustainable water resource management requires aconnection between management at the project and the hydrologic scale as they influence and impact one another.
Disclosure in this case could include copies of the relevant water code statutes, compliance mechanisms, or water
management plans. Any verification or compliance mechanism must also have the authority and ability to apply
penalties, sanctions, or another type of disciplinary action for non-compliance.
Example from San Francisco, CA: A mixture of state, federal, special commissions and agencies, and lower-level
organizations manage water across the San Francisco Bay / Sacramento River Delta region. The public utility’s
projects must be in compliance with these regulatory institutions or they will face sanction under the State Water
Code.
Relevant committees / regulatory agencies for this region include:
•

•

•

•

Delta Protection Act / Delta Protection Committee: The Delta Protection Act of 1992 created The Delta
Protection Commission, codified in the Public Resources Code (PRC) beginning with section 29700. The Act
declares that, “the Delta is a natural resource of statewide, national, and international significance, containing
irreplaceable resources, and that it is the policy of the State to recognize, preserve, and protect thoseresources of the Delta for the use and enjoyment of current and future generations, in a manner that
protects and enhances the unique values of the Delta as an evolving place.” PRC Section 29760-29767
further instructs that, “Not later than October 1, 1994, the commission shall prepare and adopt, by a majority
vote of the membership of the commission, and thereafter review and maintain, a comprehensive long-term
resource management plan for land uses within the primary zone of the delta.”

such as wetlands, and oversees a Federal Aid program that distributes hundreds of millions of dollars
to State fish and wildlife agencies. https://www.fws.gov/sfbaydelta/index.cfm
U.S. Bureau of Reclamationo Central Valley Project: The project was initially implemented primarily to protect the Central Valley
from chronic water shortages and floods, but the CVP also improves Sacramento River navigation,
supplies domestic and industrial water, generates electric power, conserves fish and wildlife, creates
opportunities for recreation, and enhances water quality. The Bureau of Reclamation is in charge ofwater supply allocation for all CVP contractors. Relevant federal statutes are found here:
http://www.usbr.gov/mp/cvpia/index.html, and disclosure of annual CVP water allocation is here:
http://www.usbr.gov/mp/cvp-water/.

Question 1.2: Are the following factors taken into account in the definition of the available resource
pool?
1.

Non-consumptive uses (e.g., navigation, hydroelectricity)

2. Environmental flow requirements
3. Dry season minimum flow requirements
4. Return flows
5. Inter-annual and inter-seasonal variability
6. Connectivity with other water bodies
7. Climate change impacts
Scoring: 1 point each for yes, maximum of 7 points, n/a if not applicable
Evidence or Disclosure: Evidence
What this means: Evidence of these criteria, expanded upon below, should be included in the relevant water
management plan. What each of these factors mean:
1. Non-consumptive use refers to water uses that do not diminish the amount of water moving through thehydrologic system or significantly alter its quality for other uses. During non-consumptive use, water is either
left instream or, if it is diverted, is returned immediately to the source following its use in the same quantityand quality as when it was diverted.
2. For surface water, are there requirements in place for instream flow levels necessary to maintain theecological function of the water resource and its ecosystem?
3. Most free-flowing waters experience seasonal fluctuations in water levels. For the waterway in question, arethere minimum flow requirements in place during dry/low-flow periods?
4. While return flows are notoriously hard to quantify, are measurements being taken or models employed toestimate the amount of water that is returned to the resource pool once it has been used?
5. As previously mentioned, most surface and some groundwater resources experience flow variability overdifferent timescales, due in part to seasonal changes in precipitation, temperature, the consumptive use rate,
land cover / land use change, and interannual climate patterns such as the El Niño Southern Oscillation(ENSO). Do the resource availability reports take these fluctuations into account?
6. Availability reports should also note whether or not the water resource in question is hydrologicallyconnected to other water resources such as an aquifer, lake, or a larger stream network or basin, as use of
the resource in one area could have a wider impact on these interconnected systems.
7. Does the availability report mention climate change and any predicted impacts climate could have on the
resource’s availability over time?
Example from San Francisco, CA: These factors are governed at the state level by the CA State Water Board, as well
as a variety of specialty groups, such as the San Francisco Public Utilities Commission (PUC), federal and statenavigation standards, SWB and US EPA environmental flow requirements, and CA energy governance committee.

http://www.waterboards.ca.gov/waterrights/water_issues/programs/bay_delta/deltaflow/docs/final_rpt080310.pdf.

Question 1.3: Is there a distinction between the allocation regimes used in “normal” times and in timesof “extreme/severe” water shortage?
Scoring: 1 if yes, 0 if no, n/a if not applicable
Evidence or Disclosure: Evidence
What this means: Within the relevant water resource management plan(s), is there an arrangement in place formodifying water deliveries (measured as either volume or percentage, or both) during times of extended or extreme
drought? Evidence of this would be a section of the water management plan addressing current / potential water
shortages and how allocation is / will be modified during those times.
Examples from San Francisco, CA: The SFPUC’s Urban Water Management Plan differentiates between allocation
under normal conditions and both short-term (1 year) and longer-term (2-4) year drought conditions. The reduced
allocations during water shortage years are based on a percentage of the total volume delivered under normal
conditions. For example, during a 1 critical dry year, allocation is cut by 10% system-wide; for years 2-4, system-wide
allocation is cut by 22%. These shortage allocations are further divided between retail public utility customers andwholesale users. The 2015 Urban Water Management Plan could be used as Evidence for this question:
http://www.sfwater.org/Modules/ShowDocument.aspx?documentID=8838. The U.S. Bureau of Reclamation also
adjusts its annual CVP water allocation plans based on drought conditions. The most recent example from 2016 isavailable here:
http://www.waterboards.ca.gov/waterrights/water_issues/programs/drought/tucp/docs/febnov_2016plan.pdf, andcould be supplied as Evidence.

Question 1.4: What arrangements are in place, if any, to accommodate the potentially adverse impactsof climate change on the resource pool?
Scoring: 1 if yes, 0 if no, n/a if not applicable
Evidence or Disclosure: Evidence
What this means: Are there plans in place to monitor the status of the water resource in question over time and, if
necessary, revise existing laws and regulations should the water be negatively affected by future climate change? Inorder to score a 1 in this category, the relevant water management plan(s) should employ the best available science
to monitor the resource and formulate a plan for addressing negative climate impacts.
Example from San Francisco, CA: The SFPUC’s 2010 and 2015 Urban Water Management Plans both outline impacts
to date and alternative plans for handling crisis periods:
http://www.sfwater.org/Modules/ShowDocument.aspx?documentID=8838. Additionally, the CA Department of
Water Resources published a detailed Climate Change Handbook for Regional Water Planning in 2011 that addresses
anticipated climate impacts to regional water supplies, as well as response protocols. Available here:
http://www.water.ca.gov/climatechange/CCHandbook.cfm. In 2015, the State Water Board adopted new drought
emergency regulations to deal with extended water shortages:
http://www.waterboards.ca.gov/waterrights/water_issues/programs/drought/emergency_regulations.shtml. Any ofthese examples could be used as Evidence in this scoring exercise.

to pre-defined priority uses, suspension of the regime plan, etc.)
Scoring: 1 if yes, 0 if no, n/a if not applicable
Evidence or Disclosure: Evidence
What this means: Increasing variability in flow can necessitate flexibility in water allocation by the relevant
government agency or public utility. Do extended or extreme drought conditions currently trigger changes by thegovernment agency or public utility to the allocation regime? Examples that could be used as Evidence include water
use restrictions or reduction in allocation authorized / mandated by the state water code.
Example from San Francisco, CA: The California Water Code’s Urban Water Management Planning statutemandates an urban water shortage contingency analysis for water providers that includes, “Stages of action to beundertaken by the urban water supplier in response to water supply shortages, including up to a 50 percent
reduction in water supply, and an outline of specific water supply conditions that are applicable to each stage.” Asmentioned in question #3, the SFPUC’s 2015 Urban Water Management Plan has outlined a water shortage
contingency plan with single and multiple dry year allocation reductions, which could be supplied of Evidence:
http://www.sfwater.org/Modules/ShowDocument.aspx?documentID=8838.

Question 1.6: For international / transboundary basins, is there a legal mechanism in place to define
and enforce water basin allocation agreements?
Scoring: 1 if yes, 0 if no, or N/A if the basin is not shared by two or more countries
Evidence or Disclosure: Disclosure
What this means: If two or more countries share the river basin or aquifer in question, is there a treaty or otherbi/multilateral agreement in place to A) Allocate water between the basin countries and, B) Enforce those allocations?
For the purposes of this scoring exercise, the existence of a shared use treaty or agreement between the riparian
countries constitutes Disclosure.
Example from the United States and Canada: The International Joint Commission (IJC), authorized by the 1909
Boundary Waters Treaty resolves all transboundary water-related disputes between the United States and Canada
and constitutes Disclosure for this question. These rulings are legally binding for all parties. From the IJC’s website:“The International Joint Commission prevents and resolves disputes between the United States ofAmerica and Canada under the 1909 Boundary Waters Treaty and pursues the common good ofboth countries as an independent and objective advisor to the two governments.
In particular, the Commission rules upon applications for approval of projects affecting boundaryor transboundary waters and may regulate the operation of these projects; it assists the twocountries in the protection of the transboundary environment, including the implementation of
the Great Lakes Water Quality Agreement and the improvement of transboundary air quality; andit alerts the governments to emerging issues along the boundary that may give rise to bilateral
disputes.”

GUIDANCE NOTE TO ISSUERS AND VERIFIERS: SUPPLEMENTARY NOTE TO THE WATER INFRASTRUCTURE CRITERIAQuestion 1.7: Are water delivery agreements defined on the basis of actual in situ seasonal/annual
availability instead of volumetric or otherwise inflexible mechanisms?
Scoring: 1 if yes, 0 if no, n/a if not applicable
Evidence or Disclosure: Evidence
What this means: Water delivery amounts can be based on a discrete volume, such as 200 mgd (million gallons perday) or as a percentage of the total resource block available at any given time. In the latter case, the actual volumedelivered may fluctuate depending on the season or annual/decadal precipitation patterns that impact the total
resource pool. Percentage-based water delivery agreements that take these fluctuations into account are preferable
because they are better able to respond and adjust in times of shortage. Evidence for the type of water delivery
mechanisms being used in the basin will most likely be found in the relevant water delivery agreement or regulatory
statute.
Example from San Francisco, CA: Water delivery to Central Valley Project customers are based on in situ conditions.
According to the U.S. Bureau of Reclamation, CVP water delivery amounts are made annually and based on “factorsthat include hydrology, changing river and Delta conditions, storage in CVP reservoirs, regulatory requirements, court
decisions, biological opinions, environmental considerations, operational limitations and input from other agencies
and organizations.” More information here: http://www.usbr.gov/newsroom/newsrelease/detail.cfm?RecordID=52228

Question 1.8: Has a formal environmental flows (e-flows)/sustainable diversion limits or otherenvironmental allocation been defined for the relevant sub-basin or basin? If preexisting, has theenvironmental flows program been updated to account for the new project?
Scoring: 1 if yes, 0 if no, n/a if not applicable
Evidence or Disclosure: Evidence
What this means: Environmental (also called ‘instream’) flow refer to the quantity, quality, and timing of water
moving through the hydrologic system required to maintain basic ecological function of the ecosystem, as well as
meet the needs of the aquatic and terrestrial communities dependent upon it. Environmental flows are left instream
and cannot be used for a non-ecosystem purpose. These can be a volumetric amount, i.e., 30 cfs (cubic feet per
second), or a percentage of total flow. Evidence of environmental flow allocation will be most likely found it therelevant water management plan.
Example from San Francisco, CA: An interagency group has developed a Bay-Delta watershed management plan,
which includes city, country, state, and federal entities. The plan allocates environmental flow targets and is regularly
updated. Referencing this Program would count as evidence for this question:
http://www.waterboards.ca.gov/waterrights/water_issues/programs/bay_delta/deltaflow/final_rpt.shtml. Similarly, for
the Tuolumne River, a detailed SFPUC instream flow plan has been prepared and could also be used for Evidence
purposes: , http://utrep.blogspot.com/2014/04/draft-oshaughnessy-dam-instream-flow.html.
Example from the Potomac River basin, USA: Evidence of environmental flow criteria can be found in the 2013

GUIDANCE NOTE TO ISSUERS AND VERIFIERS: SUPPLEMENTARY NOTE TO THE WATER INFRASTRUCTURE CRITERIAQuestion 1.9: Have designated environmental flows / allocation programs been assured /implemented?
Scoring: 1 if yes, 0 if no, n/a if not applicable
Evidence or Disclosure: Either
What this means: If there are regulatory environmental or instream flow requirements in place, are there monitoringor other verification mechanisms to ensure that these requirements are being met? Disclosure of the relevant statuteor Evidence of an instream flows monitoring program could be used to satisfy verification requirements for thisquestion.
Example from San Francisco, CA: Instream flow criteria, as mandated under the Bay-Delta Plan, are monitored by
the State Water Resources Control Board as well as the Delta Independent Science Board, and is now being
implemented: http://www.waterboards.ca.gov/waterrights/water_issues/programs/bay_delta/deltaflow/

Question 1.10: Has a mechanism been defined to update the environmental flows plan periodically(e.g., every 5 to 10 years) in order to account for changes in allocation, water timing, and water
availability?
Scoring: 1 if yes, 0 if no, n/a if not applicable
Evidence or Disclosure: Evidence
What this means: To ensure that environmental flow requirements reflect conditions in the stream or aquifer, as wellas the best available science, allocation plans should have mechanisms for periodic review built-in to allow changes
to flows based on (potentially) changing environmental requirements. Evidence would be documentation in thewater management plan that outlines periodic review processes.
Example from the Trinity River basin, California, USA: Environmental flow requirements are managed by the multiagency Trinity River Restoration Program, monitored, and updated periodically as part of their Adaptive
Environmental Assessment and Management (AEAM) program. More information about the Trinity River
environmental flow program is available here: http://www.trrp.net/restore/flows/.
Example from San Francisco, CA: The SFPUC’s Urban Water Management Plans also require an update every 5
years to ensure they reflect current conditions and the best available science. From the State Water Code’s Urban
Water Management Planning section: “10621. (a) Each urban water supplier shall update its plan at least once every
five years on or before December 31, in years ending in five and zero.”
http://www.sfwater.org/Modules/ShowDocument.aspx?documentID=8838

Question 1.11: Is the amount of water available for consumptive use in the resource pool linked to a
public planning document? (E.g., a river basin management plan)
A. Yes, the limit is linked to a river basin management plan
B. Yes, the limit is linked to another planning document, please indicate:
C. No, the limit is not linked to any planning document
Scoring: If A or B, 1; if C, 0
Evidence or Disclosure: Evidence
What this means: Consumptive use refers to any water use that removes available water from the system without
returning it (e.g., domestic consumption, crop irrigation, or industrial manufacturing). Is the total volume orpercentage dedicated for consumptive uses tied to a broader river basin management plan that takes bothconsumptive and non-consumptive uses into consideration? The relevant planning document constitutes Evidence
for this question.

Climate Bonds Initiative April 201816

GUIDANCE NOTE TO ISSUERS AND VERIFIERS: SUPPLEMENTARY NOTE TO THE WATER INFRASTRUCTURE CRITERIAExample from San Francisco, CA: The State Water Board implements the Basin Plan. All designated beneficial uses,
including all consumptive uses, are tied to the Basin Plan:“By law, the Water Board is required to develop, adopt (after public hearing), and implement a Basin Plan for the
Region. The Basin Plan is the master policy document that contains descriptions of the legal, technical, andprogrammatic bases of water quality regulation in the Region. The plan must include:• A statement of beneficial water uses that the Water Board will protect;• The water quality objectives needed to protect the designated beneficial water uses; and• The strategies and time schedules for achieving the water quality objectives.”
http://www.waterboards.ca.gov/sanfranciscobay/water_issues/programs/planningtmdls/basinplan/web/bp_ch1.shtml#
1.4.

Question 1.12: If present, is the river basin plan a statutory instrument that must be followed rather thana guiding document?
Scoring: 1 if yes, 0 if no, n/a if not applicable
Evidence or Disclosure: Either
What this means: Does the planning document referenced in question 11 have legally binding compliancemechanisms in place? Most likely this will require Disclosure of the relevant statute, but Evidence of compliancemechanisms within the basin plan is also acceptable.
Example from San Francisco, CA: The Bay-Delta Plan is required and authorized under California Water Code
Section 85000 (The Delta Reform Act of 2009):
http://leginfo.legislature.ca.gov/faces/billNavClient.xhtml?bill_id=200920107SB1&search_keywords.
As such, it is a statutory document, requiring compliance with the criteria developed by the plan. More information isavailable here: http://www.waterboards.ca.gov/waterrights/water_issues/programs/bay_delta/.

5.1.2. Section II of the Scorecard: GOVERNANCE Scoring Guide
The section of the Scorecard includes the following questions relating to how the Vulnerability Assessment addresses
the policy and governance mechanisms in place to manage and ensure user compliance with relevant water
regulations.

Question 2.1: How are water entitlements defined?
A. Purpose that water may be used for
B. Maximum area that may be irrigatedC. Maximum volume that may be taken in a nominated period
D. Proportion of any water allocated to a defined resource pool
E. No formal definition exists
Scoring: A - D = 1; E = 0; n/a if not applicable
Evidence or Disclosure: Disclosure
What this means: Water can be allocated in a variety of ways – by usage type, maximum volume, etc. In many places,
multiple criteria are used. The most common allocation methods are included (A-D) in this question. While answers
A-D all achieve a score of 1, from an adaptive water governance perspective, answer D is preferable. Water allocation
should be proportional to the amount available within the resource pool to give flexibility during times of shortageand ensure enough water remains instream to ensure proper ecosystem function.

Climate Bonds Initiative April 201817

GUIDANCE NOTE TO ISSUERS AND VERIFIERS: SUPPLEMENTARY NOTE TO THE WATER INFRASTRUCTURE CRITERIAThis question requires Disclosure in the form of the legal statute or document that defines how water entitlements
are measured. In the United States, this is often found in the state water code.
Example from San Francisco, CA: Both A and D. California, like many U.S. states, has a list of approved “beneficial
uses” to which water can be allocated. Beneficial uses include things like navigation, human consumption, irrigation,industrial use, and ecosystem services (i.e., “environmental flows”). According to the state water code, water cannot
be allocated for use in any way that is not covered by the list. Disclosure from the state water code:
Article 4. Beneficial Use [1240. - 1244.] (Article 4 enacted by Stats. 1943, Ch. 368.) § 1240. The appropriationmust be for some useful or beneficial purpose, and when the appropriator or his successor in interest ceases
to use it for such a purpose the right ceases. (Enacted by Stats. 1943, Ch. 368.)
http://www.waterboards.ca.gov/laws_regulations/docs/wrlaws.pdf.
California also allocates water proportionally based on maximum volume available. This comes into play primarily
during times of drought, when the State Water Resources Department can adjust the percentage of water deliveries
made to State Water Project (SWP) permittees, and Water Code section 1058.5 mandates that the State Water
Resources Control Board must curtail water diversions when sufficient flows in a watershed are not available because
the water is needed to satisfy senior rights or provide a correlative share of equally senior rights (i.e., riparian rights),
or is needed to meet public trust and water quality requirements. Disclosure: http://www.leginfo.ca.gov/cgibin/displaycode?section=wat&group=01001-02000&file=1050-1060.

Question 2.2: Is the surface water system currently considered to be:
A. Over-allocatedB. Over-used
C. Neither over-allocated nor over-used
Scoring: A = 0.5, B = 0, C = 1, n/a if not applicable
Evidence or Disclosure: Evidence
What this means: A. Over-allocation means that the current usage rate is within sustainable limits but there would be
a problem if all legally approved entitlements to abstract water were used at their full allotment. Over-used refers toa situation where existing abstractions exceed the estimated proportion of the resource that can be taken on asustainable basis. Evidence of either of these conditions could be in the form of a basin report or water resourcesmanagement plan that shows allocation and withdrawal percentages for the given waterway or aquifer.
Example from San Francisco, CA: The Sacramento-San Joaquin basin is currently over-allocated, meaning that
there is not enough water in the system to sustainably supply existing allocation agreements and water rights, whileleaving enough water instream to provide ecosystem services. This has led to chronic shortages and considerable
water stress, particularly during the current drought, which began in 2012. This water rights allocation report,
completed by scientists at the University of California – Davis, shows high levels of over allocation for the Sacramento,
Tuolumne, and San Joaquin rivers: https://watershed.ucdavis.edu/files/biblio/WaterRights_UCDavis_study.pdf.

Climate Bonds Initiative April 201818

GUIDANCE NOTE TO ISSUERS AND VERIFIERS: SUPPLEMENTARY NOTE TO THE WATER INFRASTRUCTURE CRITERIAQuestion 2.3: If monitored and the investment uses groundwater, is the groundwater water systemcurrently considered to be:
A. Over-allocatedB. Over-used
C. Neither over-allocated nor over-used
Scoring: A = 0.5, B = 0, C = 1, n/a if not applicable
Evidence or Disclosure: Evidence
What this means: Similar to the previous question, except referring to groundwater withdrawals. Only relevant if
groundwater is being used by the proposed bond project. Evidence of this would be an aquifer study or monitoring
report that shows current allocation and aquifer withdrawals.
Example from Australia: Groundwater in the Australian states of South Australia and Victoria are cooperatively
managed and monitored under the 1985 Victoria-South Australia Groundwater Agreement. According to the Border
Groundwaters Agreement Review Committee (BGARC), several of the shared aquifers are over-used meaning they
are being withdrawn faster than they can be sustainably replenished. Thus, if the potential bond project planned towithdraw water from one of these over-used aquifers, they would receive a score of 0 on this question. The mostrecent annual report from the BGARC is available here:
http://www.parliament.sa.gov.au/HOUSEOFASSEMBLY/BUSINESSOFTHEASSEMBLY/RECORDSANDPAPERS/TABLEDPAPERSANDPETITIONS/Pages/TabledPapersandPetitions.aspx?TPLoadDoc=true&TPDocType=0&TPP=53&TPS=2&TPIte

Question 2.4: How are limits on the amount/rate of abstraction defined?
A. There is a limit in the volume of water that can be abstracted
B. There is a limit to the proportion (e.g. percentage) of water that can be abstracted
C. There are restrictions on who can abstract the water (but no limit on how much water can be abstracted)

D. There is no explicit limit on water abstraction
Scoring: A = 0.5, B = 1, C = 0.5, D = 0, n/a if not applicable
Evidence or Disclosure: Evidence
What this means: Within the relevant water management plan, have the upper limits of water withdrawal been
defined? If so, how are they defined? The ideal limitations are proportional to the in situ amount of water available
in the pool, since water levels can and do fluctuate. If the withdrawal limits are based on a total volume, during timesof low flow, it may mean that the water withdrawn either reduces the resource pool to the point of ecosystem
impairment, or fully depletes the resource. Degraded habitat can lead to degraded water quality and quantity, further
reducing the amount of water available. On the other hand, if withdrawal limits are proportional, when water levels
drop, so too does the amount withdrawn, ensuring that more is left instream for ecosystem use.
Example from the United Kingdom: The UK Environment Agency sets abstraction limits using the percentage of thetotal resource pool. More information on water abstraction limits can be found in this document, which also serves as

GUIDANCE NOTE TO ISSUERS AND VERIFIERS: SUPPLEMENTARY NOTE TO THE WATER INFRASTRUCTURE CRITERIAQuestion 2.5: Are governance arrangements in place for dealing with exceptional circumstances (suchas drought, floods, or severe pollution events), especially around coordinated infrastructure operations?
Scoring: 1 if yes, 0 if no, n/a if not applicable
Evidence or Disclosure: Disclosure
What this means: Are there laws, policies, statutes, or management regulations in place to manage water
infrastructure during emergency situations? This is relevant for all water infrastructure, but particularly important for
combined systems such as stormwater, wastewater, and drinking water treatment facilities. Disclosure might include
the relevant statutes or laws governing emergency circumstances.
Example from San Francisco, CA: Yes, there are explicit plans for extreme events including drought, flooding, andsevere pollution, crossing a number of institutional levels. The most relevant for this issuance are described in the
Urban Water Management Plan:
Also, emergency water rights curtailments are allowed under Water Code section 1058.5, which mandates that theState Water Resources Control Board must curtail water diversions when sufficient flows in a watershed are notavailable because the water is needed to satisfy senior rights or provide a correlative share of equally senior rights(i.e., riparian rights), or is needed to meet public trust and water quality requirements. Disclosure:
http://www.leginfo.ca.gov/cgi-bin/displaycode?section=wat&group=01001-02000&file=1050-1060.
Example from Potomac River: Yes, the ICPRB holds annual drought exercises and manages reservoir operations
during times of drought; they also coordinate emergency spill operations. More information is available on theirwebsite here: https://www.potomacriver.org/focus-areas/water-resources-and-drinking-water/
They are also tasked with completing the Comprehensive Management Plan for the Potomac River, which is currently
being finalized. More information about the comprehensive plan is available here:
https://www.potomacriver.org/focus-areas/water-resources-and-drinking-water/water-resources/planning/basinwide-comprehensive-plan/

Question 2.6: Is there a process for re-evaluating recent decadal trends in seasonal precipitation andflow OR recharge regime, in order to evaluate “normal” baseline conditions?
Scoring: 1 if yes, 0 if no, n/a if not applicable
Evidence or Disclosure: Disclosure
What this means: Baseline conditions refer to the recorded “status-quo” surface water levels or aquifer(groundwater) recharge rate at any given time during the year. Climate change and other factors such as land use
and withdrawal rates can alter these baselines over time, reducing their accuracy and usefulness in planning andallocating water from the resource pool. As such, it is important that periodic review is undertaken by the relevant
water resources management division to determine if the baseline conditions are in fact changing and if a change in
withdrawal rates / volume is thus warranted. In order to score a 1 on this question, there must be a sanctioned review
process in place within the water management plan to monitor baseline conditions over time and update the plan if
and when necessary. Disclosure would be the management plan itself.
Example from San Francisco, CA: Yes. The Urban Water Management Plan is a periodic review document, based onrecent trends in water usage and flows. In accordance with the Urban Water Management Planning Act (California
Water Code Division 6, Part 2.6, Sections 10610 through 10656), the plan is updated every 5 years. Disclosure:

GUIDANCE NOTE TO ISSUERS AND VERIFIERS: SUPPLEMENTARY NOTE TO THE WATER INFRASTRUCTURE CRITERIAQuestion 2.7: Is there a formal process for dealing with new entrants?
Scoring: 1 if yes, 0 if no, n/a if not applicable
Evidence or Disclosure: Disclosure
What this means: When there are prospective water users desiring to use the resource pool, are there formal
permitting processes in place to determine if there is enough water to allocate to the new user(s), what uses areallowed, how much they can withdraw, from which point, at what rate, etc.? This will most likely be found in the stateor national water code; Disclosure consists of the relevant statue or law regarding the water permitting process.
Example from San Francisco, CA: In the western United States, each state has its own water permitting process
based on the doctrine of prior appropriation, also known as first-in-time, first-in-right. In California, the State Water
Board defines and regulates the water rights permitting application process. Detailed information on this process canbe found here: http://www.waterboards.ca.gov/waterrights/board_info/water_rights_process.shtml; the Water Rights
Commission Act of 1914, which established the water permitting system, is available here:
http://repository.uchastings.edu/cgi/viewcontent.cgi?article=1061&context=ca_ballot_props
Example from Potomac River: New entrants are managed at the state level. In Maryland, for example, there is anextensive permitting process, outlined here: http://www.dsd.state.md.us/comar/SubtitleSearch.aspx?search=26.17.06.*

Question 2.8: For existing entitlements, is there a formal process for increasing, varying, or adjustinguse(s)?
Scoring: 1 if yes, 0 if no, n/a if not applicable
Evidence or Disclosure: Disclosure
What this means: Water rights permits typically define the total volume or percentage of the resource pool that canbe withdrawn, the rate of withdrawal, season of use, point of diversion, and type of use. If the permit holder wants tochange any of these criteria, is there a formal process for them to do so? Like the previous question, Disclosure is
likely found in the relevant water rights permitting statute or law.
Example from San Francisco, CA: This process is also defined by the State Water Board. From the Board’s website:“Any change in purpose, place of use, or point of diversion requires Board approval. The proposed change cannot
initiate a new right or injure any other legal user of water.” More information is available here:
http://www.waterboards.ca.gov/waterrights/board_info/water_rights_process.shtml#process

Question 2.9: Is there policy coherence across sectors (agriculture, energy, environment, urban) that
affect water resources allocation, such as a regional, national, or basin-wide Integrated Water
Resources Management (IWRM) plan?
Scoring: 1 if yes, 0 if no, n/a if not applicable
Evidence or Disclosure: Evidence
What this means: Are water-related policies across sectors and governance scales (local, state, regional, national)
consistent with one another? This question returns to the concept of basin-scale planning. If there is a basin or subbasin management plan in place, does it include inter-agency policy planning guidelines or mechanisms to ensure
coherent policies across sectors and scales? Without such provisions in place, laws and regulations can (and do!)contradict or impair one another. Evidence of policy coherence would be the existence of interagency task forces orworking groups, or an integrated water management policy or plan.
Example from San Francisco, CA: Inter-agency coherence is managed through several mechanisms. There areinteragency processes at the state level, such as the interagency drought task force:

https://www.gov.ca.gov/docs/12.17.13_Drought_Task_Force.pdf, http://drought.ca.gov/; as well as the aforementioned
environmental flows work, both of which could be used as evidence of policy coherence across sectors. Moreinformation about integrated water management in California can be found here:
http://www.water.ca.gov/irwm/resources/ncro.cfm

Question 2.10: Are obligations for return flows and discharges specified and enforced?
Scoring: 1 if yes, 0 if no, n/a if not applicable
Evidence or Disclosure: Disclosure
What this means: Are there expected to be return flows (i.e., water returning to the resource pool following its
removal, primarily through sub-surface infiltration or surface runoff) associated with the proposed bond project? Are
those flows quantified and, if so, is there monitoring in place to ensure that the water being returned to the source
meets applicable water quality requirements?
Example from San Francisco, CA: In California, there is a network of state, local and federal agencies involved in themonitoring of return flows as part of their overall water monitoring programs in the Sacramento – San Joaquin delta.

More information is also available through the California Department of Water Resources Data Exchange
Center: http://www.cdec.water.ca.gov/

Question 2.11: Is there a mechanism to address impacts from users who are not required to hold awater entitlement but can still take water from the resource pool?
Scoring: 1 if yes, 0 if no, n/a if not applicable
Evidence or Disclosure: Disclosure
What this means: Many water uses with a relatively small withdrawal volume or percentage, such as household use,
lawn care, stock watering, etc. are routinely exempt from official entitlement processes, such as permitting
requirements. Taken together, however, these withdrawals can make a significant dent in the resource pool. In orderto score a 1 on this question, these unregulated withdrawals must be addressed by the water management plan orregulatory framework.
In the case of California, these uses are handled very explicitly, with robust regulatory mechanisms in place. Most of
the details are described in relation to the state’s Water Boards:
http://www.waterboards.ca.gov/waterrights/board_info/water_rights_process.shtml. Relevant text there includes:•

A riparian right entitles the landowner to use a correlative share of the water flowing past his or her property.
Riparian rights do not require permits, licenses, or government approval, but they apply only to the water
which would naturally flow in the stream. Riparian rights do not entitle a water use to divert water to storage
in a reservoir for use in the dry season or to use water on land outside of the watershed. Riparian rights
remain with the property when it changes hands, although parcels severed from the adjacent water source
generally lose their right to the water….

•

The Water Commission Act of 1914 established today’s permit process. The Act created the agency that later
evolved into the State Board and granted it the authority to administer permits and licenses for California’s
surface water. The act was the predecessor to today’s water Code provisions governing appropriation….

•

Permittees run the gamut from water districts and electric utilities to farmers and ranchers. Besides riparianright holders and ground water users, permits are not required of users of purchased water or those who use

Climate Bonds Initiative April 201822

GUIDANCE NOTE TO ISSUERS AND VERIFIERS: SUPPLEMENTARY NOTE TO THE WATER INFRASTRUCTURE CRITERIA
water from springs or standing pools lacking natural outlets on the land where they are located. However,unauthorized appropriation of water is against the law and can result in court action and fines.
Other options are possible too. For instance, in an OECD report on water allocation, water users without an explicit(i.e., permitted) entitlement may use quite different systems:•

In Alberta, Canada, in the case of collective entitlements, allocation of water among individual users within agroup of users is based on a bargaining process and informal trading. In the Yellow River Basin, China,
collective entitlements are assigned to an institution representing water users. Irrigation districts and public
water companies access water to consume by paying a fee. In some irrigation districts, authorities assign
water abstraction rights to clients under a permit system. For Costa Rica, in the case of collective
entitlements, the Ministry of Energy and Environment grants a concession to each Society of Water Users
according to the Water Law. These societies have the authority to decide internally the form of water
distribution amongst their members through agreements of the general assembly of members, or throughtheir own regulations. In Spain, there are both individual and collective entitlements. Collective entitlements
may be granted to Water Users Associations or Irrigators Communities, for instance. Finally, in the case ofFrance, the recently created Single Collective Management Bodies (OUGC) provide a structure and incentives
for irrigators to devise their own rules to allocate a set volume of water among themselves at the catchmentlevel. These rules are subject to approval by the Ministry of Ecology, Sustainable Development and Energy.
(p. 73, OECD 2015)

Question 2.12: Is there a pre-defined set of priority uses within the resource pool? (E.g., according to orin addition to an allocation regime)
Scoring: 1 if yes, 0 if no, n/a if not applicable
Evidence or Disclosure: Disclosure
What this means: Many states maintain a list of approved or priority uses for their water resources. These“beneficial” uses often include activities like irrigation, navigation, domestic consumption, energy production,industrial use, recreation, and environmental flows. In order to receive a water permit or right, the applicant must
demonstrate that they will use the water for one or more of these sanctioned purposes. Often times, once the permit
is granted, the water must go to that designated use and cannot be used for other purposes without a formal change
to the permit (this was addressed in question #8). Designated priority uses may also come into play during times ofshortage when decisions must be made about which uses continue to receive their full allotment.
Example from San Francisco, CA: Priority usage is clearly defined at the state level.
From the state Water Code

Question 2.13: If there are new entrants and/if entitlement holders want to increase the volume of water
they use in the resource pool, can new entitlements be issued or existing entitlements be augmented?
A. Yes, no restrictions
B. No, catchment is closed
C. Yes, if conditional on:• Assessment of third party impacts• Environmental impact assessment (EIA)• Existing user(s) forgoing use
Scoring: A = 0, B = 1, C = 1 (if conditions include one or more of 1-3, n/a if not applicable
Evidence or Disclosure: Disclosure
What this means: Has the resource pool been fully allocated, meaning that no new permits can be issued? If so, thecatchment (basin) is closed. If not, can new permits be issued or existing water permits be enlarged? If so, are there
conditions set on the new / revised permits based on potential injury to other users, potential environmental impacts,or the forfeit of usage by current permit holders? For example, in the U.S. state of California, existing water rights canbe altered only if they do not cause injury to other permitted users in the basin, including the environment.
Disclosure consists of the relevant rules and regulations related to water permitting alterations.
Example from San Francisco, CA: Permits are managed by the State Water Resources Control Board. Changes topermits and the issuance of new permits is allowed, but with restrictions. Permitting regulations are available here:
http://www.swrcb.ca.gov/waterrights/water_issues/programs/applications/#permitting.

Question 2.14: Are withdrawals monitored, with clear and legally robust sanctions?
Scoring: 1 if yes, 0 if no, n/a if not applicable
Evidence or Disclosure: Evidence
What this means: To score 1 on this question, there must be a verification mechanism in place to monitor withdrawal
amounts and ensure compliance with all applicable state and federal water regulations. The public utility, irrigation
district, or other monitoring entity must be legally able to apply penalties or sanctions for non-compliance.
Example from San Francisco, CA: Sanctions for illegal water withdrawals are clear, legally binding, and subject tocivil and criminal actions. Evidence from the state Water Code: “The State Board also is responsible for investigating
possible illegal, wasteful or unreasonable uses of water, either in response to a complaint or on the State Board’s own
initiative. If the State Board’s staff investigation determines that a misuse of water is occurring, the Board generally
notifies the affected persons and allows a reasonable period of time to terminate the misuse. The State Board may
also hold a hearing to determine if a misuse of water has occurred or is occurring. Water users who do not terminate
a misuse of water are subject to various administrative enforcement measures including possible fines and revocationof a permit or license. In appropriate cases, the State Board may also seek judicial relief in the courts.”
As of 2015, the State has also adopted even more stringent monitoring and reporting guidelines for water withdrawal
infractions, excerpted here:

Question 2.15: Are there conflict resolution mechanisms in place?
Scoring: 1 if yes, 0 if no, n/a if not applicable
Evidence or Disclosure: Either
What this means: When dealing with water rights, conflicts between users, government officials, and nongovernmental organizations are quite common. In order to score 1 on this question, there must be a legally binding
dispute resolution mechanism or process in place to deal with these issues when they arise. Disclosure would be theexistence of a dispute resolution mechanism, Evidence could be a less formal, i.e., non-statutory, process foraddressing and resolving disputes within the water management plan.
Example from the Danube River Protection Convention: This legally binding river management convention includes
an Article addressing dispute resolution, which counts as Disclosure for the purposes of this scoring exercise. The
two mechanisms they sanction are settlement through the International Court of Justice or through the use of theirown arbitration mechanism, outlined in the text.

Article 24
Settlement of disputes(1) If a dispute arises between two or more Contracting Parties about the interpretation or application of thisConvention, they shall seek a solution by negotiation or by any other means of dispute settlement
acceptable to the parties to the dispute, if appropriate with assistance by the International Commission.

5.1.3. Section III of the Scorecard: DIAGNOSTIC ASSESSMENT Scoring Guide
This is the final section of the Scorecard that assesses the Vulnerability Assessment. It deals with the technicalcomponents of water management and planning, including hydrologic models, historical climate data, and future
uncertainty. In order to score well in this section, robust hydrologic models of the water resource in question shouldbe employed by the issuer to ensure that the bond proceeds go towards investments that are robust to futureclimate scenarios. A good place to start tracking down this information is with your environmental planning or water
resources department. Civil engineering may also be a useful resource. For example, in the United States, the U.S.
Army Corps of Engineers manages hydrological analysis and climate change preparedness as it relates to U.S. water
infrastructure. Reaching out to technical leads within these departments is recommended, as some of the data may
not be publicly available or difficult to track down / verify independently.

Question 3.1: Does a water resources model of the proposed investment and ecosystem (or proposed
modifications to existing investment and ecosystem) exist? Specify model types, such as WEAP,
SWAT, RIBASIM, USACE applications). Scale should be at least sub-basin.
Scoring: 1 if yes, 0 if no, n/a if not applicable
Evidence or Disclosure: Evidence
What this means: Hydrological models such as the Water Evaluation and Planning (WEAP) system are computer
programs that use mathematical equations to represent relevant processes in the hydrologic cycle. These decision
support tools (DSTs) are used by planners to simulate water demand, supply, cycling, instream flow requirements,
ground and surface water storage capacity, climate change, and more within a given basin or sub-basin. These canbe open-source, like WEAP, or proprietary systems. Hydrological models can be used to simulate the impact of anew project or the modification of existing infrastructure or management regimes on the relevant hydrologic systemover time, under a variety of conditions. In order to score 1 on this question, a hydrological model must be used todetermine the potential hydrological impacts of the proposed bond project. Evidence is the hydrologic model itself.
Example from the Potomac basin: For basin planning and e-flow modeling, the Interstate Commission on the
Potomac River Basin (ICPRB) uses the USGS Hydrological Simulation Program—Fortran (HSPF) model:
http://water.usgs.gov/software/HSPF/. Every five years, the ICPRB also uses a long-term water-planning tool called
the Potomac River and Reservoir Simulation Model (PRRISM) to evaluate whether future water demands can be metby the current WMA water supply system under a variety of future climate change scenarios. More information about
this tool and the Commission’s climate forecasting for the Potomac River is covered in this report:
https://www.potomacriver.org/wp-content/uploads/2014/12/ICPRB13-071.pdf
Example from San Francisco, CA: California uses the HFAM II model, which is a continuous simulation model
designed for both historical and forecast analysis. More information about this model is available here:
http://www.hydrocomp.com/HfamSoftware/Hfam%20II%20Description.htm.

Climate Bonds Initiative April 201826

GUIDANCE NOTE TO ISSUERS AND VERIFIERS: SUPPLEMENTARY NOTE TO THE WATER INFRASTRUCTURE CRITERIAQuestion 3.2: Can the system model the response of the managed water system to varied hydrologic
inputs and varied climate conditions?
Scoring: 1 if yes, 0 if no, n/a if not applicable
Evidence or Disclosure: Evidence
What this means: Using a model that can be adjusted to simulate a variety of hydrologic and climatic conditions overdifferent time scales is potentially important in determining the proposed bond project’s impact on the water
resource over time. Because there is a considerable level of uncertainty around climate change impacts at the local
or basin scale, it is important to model multiple scenarios to better prepare for a range of future conditions.
Independent of climate change, the managed water system can be altered by a variety of inputs such as population
growth or land use management, and those should be accounted for as well. Evidence for this is the ability of themodel to be adjusted to multiple climate and hydrologic conditions.
Example from San Francisco, CA: The HFAM II model referenced in Question 1 of this section is a comprehensivemodeling system that simulates hydrologic processes (runoff from rainfall and snowmelt, channel flow) and theoperation of existing or planned water resource facilities (reservoirs, hydro plants, irrigation systems). It can be
adjusted to simulate a wide variety of historical, current, and future scenarios. It has been used for design or
operations analysis for many large irrigation, water supply and hydroelectric projects.
http://www.hydrocomp.com/HfamSoftware/Hfam%20II%20Description.htm

Question 3.3: Are environmental performance limits (ecosystem, species, ecological community) and/or
ecosystem services specified?
Scoring: 1 if yes, 0 if no, n/a if not applicable
Evidence or Disclosure: Evidence
What this means: Questions 3-7 in this section deal with environmental performance limits and their application to
the hydrologic model. “Environmental performance limits” is a term of art that refers to the ecological andhydrological variables that can be monitored and evaluated to define the limits of environmental tolerance. These
performance limits can be variously defined, such as in relation to environmental water quality, flow rates, ecosystemservices such as water purification, habitat qualities or population levels for endangered or significant species, or thepresence / absence of groups of species composing particular ecological communities. Performance limits are theindicators of progress, success, or failure of environmental variables. In many cases, these environmental performance
limits will have some regulatory or legal component. Environmental performance limits should be specific, clear, andoperational. They are probably monitored by environmental or natural resource staff. In some cases, they may also
include terrestrial systems, such as forests that support water quality services. For credit here, these should beincorporated into the monitoring and evaluation process — ideally represented through the modeling software but
they may also be defined in more qualitative or non-model based regulatory guidelines or strictures and/or explicit
boundaries defined internally or by external groups.
Example from San Francisco, CA: Ecosystem performance limits are taken into account in the HFAM II model andare defined and monitored / evaluated by the California Climate Change Technical Advisory Group, which include
flow regime and snowpack timing and levels.

Question 3.4: Can these performance limits be defined and quantified using the water resources
model?
Scoring: 1 if yes, 0 if no, n/a if not applicable
Evidence or Disclosure: Evidence
What this means: Can the hydrologic model incorporate the relevant environmental performance limits? Evidence of
this includes the ability to calibrate the model to simulate environmental performance under a variety of current andfuture climate conditions.

Climate Bonds Initiative April 201827

GUIDANCE NOTE TO ISSUERS AND VERIFIERS: SUPPLEMENTARY NOTE TO THE WATER INFRASTRUCTURE CRITERIAExample from San Francisco, CA: This memo on the Upper Tuolumne River provides a good example and can beused as Evidence to show what the HFAM II model can simulate in terms of quantified environmental performance
limits for precipitation and runoff in a variety of future climatic scenarios:
https://infrastructure.sfwater.org/fds/fds.aspx?lib=SFPUC&doc=751346&data=289268210. The full report is available
here: http://utrep.blogspot.com/2012/12/tuolumne-climate-change-sensitivity.html.

Question 3.5: Have these limits been defined based on expert knowledge and/or scientific analysis?
Scoring: 1 if yes, 0 if no, n/a if not applicable
Evidence or Disclosure: Evidence
What this means: Environmental performance limits should not be arbitrarily set; they should be based on scientificanalysis. Evidence could be a description of how the environmental performance limits were calculated – either by ahydrologic / climate model or through another form of rigorous scientific analysis.
Example from San Francisco, CA: In the case of the Upper Tuolumne River basin, yes, the environmental
performance limits of the hydrologic system are defined based on the HFAM II model outputs (i.e., scientific analysis).

Question 3.6: Are these performance limits linked to infrastructure operating parameters?
Scoring: 1 if yes, 0 if no, n/a if not applicable
Evidence or Disclosure: Evidence
Example from San Francisco, CA: HFAM II can specify infrastructure operating rules, in this case for the San Pedro
dam on the Tuolumne River. This allows the modeler to simulate changes to dam operations and climate scenarios
on stream flow and Hetch Hetchy Reservoir levels. http://utrep.blogspot.com/2012/12/tuolumne-climate-changesensitivity.html.

Question 3.7: Are these limits linked to an environmental flows regime?
Scoring: 1 if yes, 0 if no, n/a if not applicable
Evidence or Disclosure: Evidence
What this means: An environmental flows regime refers to the flow regime required in a river to achieve desired
ecological objectives. Understanding the environmental performance limits of these ecological objectives can help
determine the flow level required to maintain overall eco and hydrological function.
Example from San Francisco, CA: The Upper Tuolumne River Ecosystem Program manages the environmental flow
regime for the Tuolumne River. Their 2012 report, using modeled data from HFAM II, documents potential changes
to environmental performance of the hydrologic system, including environmental flow levels, under a range of futureclimate and water resource management scenarios. The report can be found here:
http://utrep.blogspot.com/2012/12/tuolumne-climate-change-sensitivity.html.

Question 3.8: For new projects, is there an ecological baseline evaluation describing the pre-impact
state?
Scoring: 1 if yes, 0 if no, n/a if not applicable
Evidence or Disclosure: Evidence
What this means: Evaluating current (pre-project) ecological conditions (“baselines”) provide a reference that helps
managers understand, track, and quantify project impacts (if any) over time.
In order to score 1 on this question, an ecological evaluation must be done prior to project approval andcommencement. In this case, Evidence would be the baseline evaluation.

Climate Bonds Initiative April 201828

GUIDANCE NOTE TO ISSUERS AND VERIFIERS: SUPPLEMENTARY NOTE TO THE WATER INFRASTRUCTURE CRITERIAExample from San Francisco, CA: One of the primary goals of the Upper Tuolumne River Ecosystem Program is to“describe historical and present day upper Tuolumne River ecosystem conditions and assess the relationship ofhistorical and present day conditions to Hetch Hetchy Project operations.” Baseline conditions for the river can befound in the Upper Tuolumne River: Description of River Ecosystem and Recommended Monitoring Actions report,
accessed here: http://utrep.blogspot.com/p/reports-and-publications.html. This report could be used as Evidence ofa baseline assessment.

Question 3.9: For rehabilitation / reoperation projects, is there an ecological baseline evaluation
available before the projects was developed?
Scoring: 1 if yes, 0 if no, n/a if not applicable
Evidence or Disclosure: Evidence
What this means: In order to score 1 on this question an ecological evaluation of the resource pool would need tohave been completed prior to the original project’s commencement. The evaluation does not have to have been
completed by the issuer, but the issuer needs to have access to it.
Example from San Francisco, CA: Environmental conditions have been monitored in the Sacramento – San Joaquindelta under the Environmental Monitoring Program (EMP) since 1971. The program is carried out jointly by the UnitedStates Bureau of Reclamation (USBR) and the California Department of Water Resources (DWR), with assistance fromthe California Department of Fish and Game (CDFG) and the United States Geological Survey (USGS). The primary
purpose of the EMP is to provide necessary information for compliance with flow-related water quality standards
specified in the water right permits. In addition, the EMP also provides information on a wide range of chemical,
physical and biological baseline variables. All of this data can be submitted as Evidence. More information isavailable here: http://www.water.ca.gov/iep/activities/emp.cfm

Question 3.10: Has there been an analysis that details impacts related to infrastructure construction
and operation that has been provided?
Scoring: 1 if yes, 0 if no, n/a if not applicable
Evidence or Disclosure: Evidence
What this means: The construction process can have a significant environmental impact, as can the ongoing
operations and management of the project / investment itself. Have both aspects been formally evaluated? Evidence
could be an environmental impact assessment or statement documenting projected impacts from construction andoperation of the project.
Example from Duluth, Minnesota, USA: In 2015, St. Louis County submitted an Environmental Assessment
Worksheet (EAW) to the state pollution control agency for an aquatic habitat restoration project that would use
dredge material from the St. Louis River navigation channel to recreate the optimal water depth and flow conditions
needed to support benthic habitat in the river’s estuary. Even though this is a restoration project, there can still be
impacts to the waterway, particularly during the construction phase. As part of the assessment, the project proposer
is required to address impacts from placing dredged material in the project area, and identify best management
practices (BMPs) to mitigate any adverse impacts. According to the EAW, these impacts include:…short-term turbidity impacts in the water column where the dredged material is placed and also
downstream of this area… To help offset impacts to the fishery, the work will not occur during spawningperiods as required in all state and federal agency permit requirements… the Proposer does not anticipate
the Project will create long-term contaminant releases.
Furthermore, the ecological risk assessment does not expect significant adverse long-terms changes frombackground levels for either contaminants or pathogenic organisms.

http://www.water.ca.gov/pubs/environment/hetch_hetchy_restoration_study/hetch_hetchy_restoration_study_appendi
ces.pdf.

Question 3.11: Are lost species and/or lost or modified ecosystem functions specified for restoration in
the environmental evaluation?
Scoring: 1 if yes, 0 if no, n/a if not applicable
Evidence or Disclosure: Evidence
What this means: In regions that have experienced the loss of native species and/or normal (“baseline”) ecosystem
function, does the bond project include a plan to address these losses through habitat restoration, reintroduction,
improved environmental flows, etc.? If so, the plan can be used as Evidence for this question.
Example from San Francisco, CA: Restoration activities are explicitly laid out in the 2010 flow criteria development
document, beginning on page 43, available here:
http://www.waterboards.ca.gov/waterrights/water_issues/programs/bay_delta/deltaflow/docs/final_rpt080310.pdf

Question 3.12: Have regional protected areas / nature reserves been included in the analysis for
impacts from the investment asset and future climate impacts?
Scoring: 1 if yes, 0 if no, n/a if not applicable
Evidence or Disclosure: Evidence
What this means: Protected areas or reserves refer to legally-designated areas that are off-limits to resource
extraction such as logging, fishing, or, mining, and may have limits on non-extractive human activities within thereserve such as boating or hiking. While your proposed bond project is likely located outside of these areas, it may
still impact these reserves. To score 1 on this question, protected areas and the potential impacts to them must be
taken into account in the environmental assessment.
Example from San Francisco, CA: For a good example, refer to the Upper Tuolumne River Ecosystem Program,which is led by the SFPUC and includes operation of the San Pedro dam, Hetch Hetchy Reservoir. The Upper
Tuolumne also flows through Yosemite National Park. The park is taken into water resource management decisions
and conditions within the park are monitored to ensure that river operations are not having a detrimental impact on
the protected area. Monitoring reports from the park could be used as Evidence for this question.
http://utrep.blogspot.com/p/reports-and-publications.html

Question 3.13: Does the model include analysis of regression relationships between climateparameters and flow conditions using time series of historical climate and streamflow data?
Scoring: 1 if yes, 0 if no, n/a if not applicable
Evidence or Disclosure: Evidence
What this means: Historical climate and streamflow data is often used to model future hydrologic conditions undera range of climate scenarios. Evidence for this question will likely come from the model itself. If you’re unsure, checkwith the hydrologic model developers.
Example from San Francisco, CA: The HFAM II uses regression analysis to estimate the relationship between
streamflow and climate change over time. Evidence from the Upper Tuolumne River basin study:
The current Tuolumne HFAM model system includes: HFAM program, version 2.3 watershed input files that describe
the physical characteristics of the watershed (topography, soils, vegetation, channel reaches) and the operations ofreservoir spillways and outlets, diversions, tunnels and power houses

Question 3.14: Does the model include climate information from a multi-modal ensemble of climate
projections (e.g., from the Climate Wizard or the World Bank’s Climate Portal) to assess the likelihoodof climate risks for the specified investment horizon(s)?
Scoring: 1 if yes, 0 if no, n/a if not applicable
Evidence or Disclosure: Evidence
What this means: Climate risks may vary over time, so it is important to understand and plan for these potential risks
over the expected lifetime of the project. This is particularly important for projects involving water infrastructure that
may be in place for 50+ years. Most hydrologic models, such as WEAP, use climate projections from theIntergovernmental Panel on Climate Change (IPCC) to model future climate risks such as droughts or flooding over avariety of timescales (usually 10-100 years). If you’re unsure where the climate data used by your hydrologic model
comes from, check with the model developer.
Example from San Francisco, CA: The HFAM II uses IPCC climate projections to model climate risks at the basin
scale over multiple time scales. More information can be found here:
http://www.hydrocomp.com/applications/Climate%20Change.htm

Question 3.15: Are changes in the frequency and severity of rare weather events such as droughts andfloods included?
Scoring: 1 if yes, 0 if no, n/a if not applicable
Evidence or Disclosure: Evidence
What this means: Changes to the frequency, timing, and severity of extreme hydrologic events are predicted undermost of the IPCC’s future climate scenarios. A robust hydrologic model should be able to model these changes.
Example from San Francisco, CA: According to the San Francisco Public Utilities Commission’s 2012 report on thesensitivity of the upper Tuolumne River to climate change, the HFAM II model predicts that in critically dry years,
reductions in annual runoff into the Hetch Hetchy Reservoir would be significantly greater, with runoff decreasing up
to 46.5% from present day conditions by 2100. These predictions can be used as Evidence for this question. Report isavailable here: http://utrep.blogspot.com/p/reports-and-publications.html.

Question 3.16: Are sub-annual changes in precipitation seasonality included?
Scoring: 1 if yes, 0 if no, n/a if not applicable
Evidence or Disclosure: Evidence
What this means: Similar to the previous question, climate change may induce changes to seasonal precipitation
patterns. In the Pacific Northwest of the United States, for example, it is predicted that summer rainfall may decrease
by up to 30% over the next century, with rain accumulating primarily in heavy, infrequent downpours. The hydrologic
model used for the adaptation plan should be able to simulate these changes.
Example from Alaska, USA: Scientists at Texas A&M University employed the widely-used Soil and Water
Assessment Tool (SWAT) to model monthly stream flow under different climate scenarios in the Cook Inlet watershedof south-central Alaska. Like the C2VSim model, SWAT is a physically based, continuous time watershed model thatis used to predict the impacts of land management practices on water and sediment in complex watersheds over aranges of scales over an extended period of time. Its time-steps can be adjusted for annual, seasonal, and monthly
changes. The data provided by the model can help inform future adaptation planning and response efforts in southcentral Alaska, and beyond. More information about the Cook Inlet project can be found in a 2015 paper published

about the SWAT model that could be used as Evidence for this question can be found here: www.swat.tamu.edu.

Question 3.17: Is GCM climate data complemented with an analysis of glacial melt water and sea level
rise risks, where appropriate (e.g., high or coastal elevation sites)?
Scoring: 1 if yes, 0 if no, n/a if not applicable
Evidence or Disclosure: Evidence
What this means: In addition to climate change, rapid glacial melting and rising sea levels may significantly impact
many regions around the world. Increasing flood events in alpine areas near existing glaciers and along low-lying
coasts are widely predicted over the next 10-100 years. If the proposed bond project is located in or near a region
that may be affected by glacial melt or sea level rise, does the hydrologic model take these factors into account?
Example from San Francisco, CA: Because San Francisco is located in a low-lying coastal delta, even a small
amount of sea level rise is predicted to impact its freshwater supplies. Sea level rise is addressed in many places,
including the following coastal planning document: http://onesanfrancisco.org/wp-content/uploads/Guidance-forIncorporating-Sea-Level-Rise-into-Capital-Planning1.pdf, which could be submitted as Evidence.

Question 3.18: Is paleo-climatic data (e.g., between 10,000 and >1000 years before present) included?
Scoring: 1 if yes, 0 if no, n/a if not applicable
Evidence or Disclosure: Evidence
What this means: Paleo-climatic data refers to historical climate data from past geological ages, such as the
Pleistocene. This data comes from a wide variety of sources including tree-rings, ice cores, and lake sediment andhelps scientists understand past instances of rapid climate change as well as the consequences for biotic communities
living at that time. Reports detailing paleo-climatic data and its use in the hydrologic model constitute Evidence forthis question.
Example from San Francisco, CA: Not currently included in the model, but is planned using this document:
http://www.water.ca.gov/waterconditions/docs/tree_ring_report_for_web.pdf.

Question 3.19: Is the number of model runs and duration of model runs disclosed?
Scoring: 1 if yes, 0 if no, n/a if not applicable
Evidence or Disclosure: Evidence
What this means: Various data sets should be explored through the hydrologic-climate model through multiple
simulations and runs, essentially testing hypotheses, system sensitivity, and alternate conditions. For Evidence
purposes, you can confirm the simulation model type with the developer.
Example from San Francisco, CA: The HFAM II software is a continuous simulation model, which runs every hour,
tracking interactions between meteorological data and streamflow over time. Described here:

The California Central Valley Groundwater-Surface Water Simulation Model (C2VSim) is another dynamic hydrologic
model used to simulate water movement through land surface, groundwater, and surface water flow systems in

What this means: A sensitivity analysis in this context refers to the degree to which a given system or component ofa system is affected by changes to future water conditions. The change can be direct: for example, the sensitivity of agiven fish species to a 2C rise in water temperature. It can also be indirect: for example, damages caused by coastal
flooding due to sea level rise. The sensitivity analysis itself is the Evidence for this question.
Example from San Francisco, CA: The San Francisco Public Utilities Commission’s Sewer System Improvement
Program (SSIP) is addressing the sensitivity of its wastewater / stormwater infrastructure to changing climate and sea
level rise. More information about this program can be found here: http://www.sfwater.org/index.aspx?page=116

Question 3.21: Is directly measured climate data available for more than 30 years and incorporated into
the VA?
Scoring: 1 if yes, 0 if no, n/a if not applicable
Evidence or Disclosure: Evidence
What this means: Historical climate data (30 years or more) for the basin or sub-basin in question should always be
incorporated into a vulnerability assessment when it is available because the longer period of record gives a clearer
picture of the typical climatic cycles (seasonal, annual, decadal) that may impact the basin’s hydrologic cycle. Data
from a shorter time period may miss these longer-term cycles and will be less useful for accurate vulnerability analysis
and future planning. The historical climate data can be provided as Evidence for this question.
Example from San Francisco, CA: Directly measured climate data dating to 1976 was included in the Public Utilities
Commission’s vulnerability assessment and 2015 Urban Water Management Plan, referenced throughout thisdocument. This data was used to develop a design drought sequence more severe than the worst drought onrecord, and rationed allocation amounts for multiple dry years.
In the Upper Tuolumne River basin, directly measured climate data dating to 1922 has been used by University ofCalifornia – Davis and Environmental Defense to model future stream flow. Data from these models were also
incorporated into the 2006 Hetch Hetchy Restoration Study, available here:
http://www.water.ca.gov/pubs/environment/hetch_hetchy_restoration_study/hetch_hetchy_restoration_study_report.p
df.

Question 3.22: Does the VA show that climate change has already had an impact on operations andenvironmental targets? Are these impacts specified and, to the extent possible, quantified?
Scoring: 1 if yes, 0 if no. If yes, an adaptation plan is needed.
Evidence or Disclosure: Evidence
What this means: Climate change and sea level rise are already impacting infrastructure and the environment inmany places around the world. Quantifying these impacts is notoriously difficult, but efforts to do so are becoming
more common. If the vulnerability assessment demonstrates that climate change and/or sea level rise is alreadyoccurring, an adaptation plan that addresses these changes and how the utility plans to adjust is needed. Adaptationplans are discussed further in Section 4.1.6.
Example from San Francisco, CA: The San Francisco Sea Level Rise strategy document addresses both thevulnerability of the system and the city’s adaptation plan. More information can be found here:

GUIDANCE NOTE TO ISSUERS AND VERIFIERS: SUPPLEMENTARY NOTE TO THE WATER INFRASTRUCTURE CRITERIAQuestion 3.23: Does the VA show that climate change will have an impact on operations andenvironmental targets over the operational lifespan? Are these impacts specified and, to the extent
possible, quantified?
Scoring: 1 if yes, 0 if no. If yes, an adaptation plan is needed.
What this means: Similar to the previous question, if the vulnerability report indicates a future impact from climatechange or sea level rise, an adaptation plan is also needed.
Example from San Francisco, CA: In the same planning document, the text states: “As a consequence of rising sea
level, San Francisco will experience more frequent and severe coastal flooding than in the past. Areas that currently
experience infrequent flooding will be inundated more often and more areas along our shorelines will be exposed toperiodic flooding than in the past or today. Sea level rise, therefore, poses a pervasive and increasing threat along
San Francisco’s shorelines.” Using data from the National Research Council (2012), it goes onto quantify the potential
amount of sea level rise over the next 100 years (See Table X.)
Example from Potomac River: Yes, as mentioned in question 1 of this section, there is a climate change planningdocument detailing potential climate impacts for the region, which indicates that there are several

Question 3.24: Is there a discussion of the uncertainties associated with projected climate impacts on
both operations and environmental impacts?
Scoring: 1 if yes, 0 if no, n/a if not applicable
Evidence or Disclosure: Evidence
What this means: There is a great deal of uncertainty about the specific impacts of climate change, particularly at thebasin scale. The best available science now informs us that there are likely to be a variety of impacts related toprecipitation patterns and the timing and frequency of extreme weather events, wildfire, and drought. Thus, multiple
projections are used to simulate a range of future scenarios. Vulnerability assessment and resource planning should
acknowledge this uncertainty and address how uncertainty and risk will be dealt with.
Example from San Francisco, CA: Uncertainty is thoroughly addressed in the CA Water Resources Department’s
Climate Change Handbook for Regional Water Planning. Planning is based on the projected “worst case scenarios”
for both drought and sea level rise. This document could be submitted as Evidence for this scoring question:
http://www.water.ca.gov/climatechange/docs/Section%207%20Planning%20Under%20Uncertainty-Final.pdf.
Example from Potomac River basin: Uncertainty is built into the ICPRB’s planning documents, including the 2010
Washington Metropolitan Area Water Supply Reliability Study Part 2: Potential Impacts of Climate Change report,
excerpted here:
Limitations and Uncertainties
Projections of future climate are subject to considerable uncertainty, since global climate models cannot
capture the full complexity of the earth’s inter-related land, water, and atmospheric systems. Thought it ispredicted that precipitation will increase on a global scale, in many areas, including the Potomac River basin,models differ on whether precipitation will increase or decrease. Watershed models are used to simulate theeffect of a changing climate on stream flows, adding additional uncertainty.
Finally, though it’s believed that as the earth warms, the variability of climate is likely to increase, withextreme weather events becoming more frequent and more intense, this change is not well represented bymost currently available global model output. This study uses the historical variability in temperature andprecipitation from a relatively short period to represent potential future variability. This historical period
includes a moderate drought, but does not capture the full range of conditions that could be experienced in

Section IV of the Scorecard: Adaptation Plan scoring guide (if applicable)

If the issuers’ Vulnerability Assessment states that there are realized and/or potential climate impacts, the issuer willneed to prepare and provide for assessment their associated adaptation plan. In that circumstance, the fourth sectionof the Scorecard is used to evaluate that Adaptation Plan.
There are 5 questions in this fourth section, which are explained below.

Question AP.1: Is there a plan to restore or secure lost / modified ecosystem functions / species?
Confer Vulnerability Assessment
Scoring: 1 if yes, 0 if noEvidence or Disclosure: Evidence

What this means: A primary function of the adaptation plan should be to address existing and potential changes tothe ecosystem function of the water resource, meaning changes to the quantity, quality, location, and timing of waterin the system. Such changes can have a negative effect on the biogeochemical processes required for native plant
and animal survival, as well as on the ecosystem services that nourish and fulfill human life. Specific steps to botharrest current and/or future degradation and improve ecosystem function under a changing climate should be
included in the plan. Examples could include riparian corridor restoration to improve stream bank stabilization and offchannel habitat for aquatic and riparian-dependent species, or an aquifer recharge project intended to replenish
depleted groundwater reserves and reduce land subsidence.
Example from San Francisco, CA: The Tuolumne River environmental flows management plan addresses ecosystemservices as well as species loss. The Upper Tuolumne River Ecosystem Program (UTREP) has been implemented to
conduct long-term, collaborative, science-based investigations designed to (1) describe historical and present day
upper Tuolumne River ecosystem conditions, (2) assess their relationship to Hetch Hetchy Project reservoir
operations, and (3) develop projects and plans for improving ecosystem conditions on a long-term, adaptively
managed basis. Under the umbrella of UTREP, many projects to monitor and address ecosystem function andbiodiversity have been undertaken. Here are links to a few of these projects:••

The Looking Downstream Project: This project is designed to better understand the physical and ecologicalprocesses of the Tuolumne River. A primary goal of the project is to “provide information that water
managers can use to manage environmental water releases from O’Shaughnessy Dam in ways that will moreclosely replicate natural physical processes and benefit water-dependent ecosystems downstream of thedam.” More information is available here:
https://drive.google.com/file/d/0ByXbtqrXtQ1LX3U5Q0ZsckRJU28/view
O’Shaughnessy Dam Instream Flow Management Plan: The purpose of this project is to “describe thedevelopment and implementation of a new instream flow regime for O’Shaughnessy Dam that is designed to
mimic natural hydrology and provide broad support for physical processes, habitats, and native species
within the Hetch Hetchy Reach of the upper Tuolumne River.” This plan is currently in Phase II and more

Question AP.2: Is the adaptation plan for environmental targets / infrastructure robust across specified
observed / recent climate conditions? Confer Vulnerability Assessment.
Scoring: 1 if yes, 0 if noEvidence or Disclosure: Evidence
What this means: The goals of the adaptation plan should be tied to specific, verifiable, current climate conditions.
In the case of San Francisco, changes in the timing of spring runoff have already led to lower summer soil moisture as
reduced winter snowpack and earlier spring runoff have decreased summer stream and base flows. These alterations
to the hydrologic cycle have widespread implications for ecosystem function and biodiversity in the region, watersupply for San Francisco and San Joaquin Valley farmers, and power generation at the O’Shaughnessy and La Grange
dams. Thus, the Public Utilities Commission’s environmental targets should specifically address the issues of watertiming and storage in the adaptation plan.
Example from San Francisco, CA: As mentioned, the observed impacts of both climate change and sea level rise
have already been significant in the Sacramento – San Joaquin watershed. The Sewer System Improvement Project(SSIP) is designed to be robust to current impacts, including excess stormwater / wastewater discharge, flooding, andsaltwater intrusion. More information is available here: http://sfwater.org/index.aspx?page=607.

Question AP.3: Is the adaptation plan for environmental targets / infrastructure robust across specified
projected climate conditions? Confer Vulnerability Assessment.
Scoring: 1 if yes, 0 if noEvidence or Disclosure: Evidence
What this means: Similar to the previous question, but addressing future conditions. Predicting the future trajectoryof climate change and its associated impacts at the watershed level is a challenging task and there is a great deal of
uncertainty involved. However, based on current impacts and downscaled climate models, climate scientists havebeen able to identify a range of projected scenarios that can be anticipated and planned for with confidence. For
example, in many low-lying coastal areas sea level is predicted to rise anywhere from 1 – 4 feet (0.3-1.4 meters) overthe next 75 years. Adaptation plans for these regions should address how project managers will ensure the resilienceof project infrastructure and / or ecosystem function under multiple elevated water conditions.
Example from San Francisco, CA: The SSIP has extensive plans for changes in a range of outcomes for sea level riseand climate variability. For example, in 2010, a design standard was drafted to incorporate the infrastructure impacts
of projected sea level rise in the planning, design, construction, operation, and maintenance of facilities directly or
indirectly related to the wastewater system, coastal erosion, overflow structure protection, and flooding, using tidal
projections based on a 1.4 m (55 in.) sea level rise by 2100. IPCC future warming scenarios project sea level rise of
0.5-1.4 m above 1990 levels and the design standard uses the most severe scenario for its planning guidelines.
Combining historical data and future projections based on the 1.4 m benchmark, Figure X demonstrates thevulnerability of San Francisco’s existing combined sewer infrastructure to overflow during high tides. This
information can then be used in the SSIP decision-making process.
More recently, a Sea Level Rise Coordinating Committee was formed by the San Francisco Planning Department andis overseeing the development of a city-wide Sea Level Adaptation Plan, due to be completed in 2018. Moreinformation can be found on the committee’s website, here: http://sf-planning.org/sea-level-rise-action-plan .
The San Francisco Public Utilities Commission is also a co-founder of the Water Utility Climate Alliance (WUCA), a
partnership between 10 of the largest water providers in the United States. The Alliance works to assess and adapt tothe potential effects of climate change through collaborative action, and to improve water management decision

making in the face of climate uncertainty. Recent publications include Embracing Uncertainty: A Case Study
Examination of How Climate Change is Shifting Water Utility Planning and Changes in Water Use Under Regional
Climate Change Scenarios. Both are available on the WUCA website: www.wucaonline.org.

Question AP.4: Is there a monitoring plan designed to track ongoing progress and impacts to informfuture decisions?
Scoring: 1 if yes, 0 if noEvidence or Disclosure: Evidence
What this means: Because there is an inherent level of uncertainty about future climate conditions, the adaptation
plan should include monitoring mechanisms and review processes in order to ensure project effectiveness and, if
necessary, to make adjustments. For example, if riparian habitat restoration is undertaken along a stream corridor to
improve ecosystem function, there should be monitoring before, during, and after the restoration activity takes placein order to gauge its effectiveness in achieving the outcomes it was designed for, both now and in the future.
Monitoring data can also be fed into larger stream monitoring networks that track climate change over time.
Example from San Francisco, CA: The Urban Water Management Plan for San Francisco is updated every 5 years
and documents ongoing efforts to reduce urban water demand and comply with the California Urban Water
Conservation Council. One such effort is the city-wide upgrade to San Francisco’s water metering system. The newmeters are helping to improve reliable water use monitoring and track compliance with water efficiency targets overtime. Detailed discussion is available in Section 9 of the report, found here:
http://www.sfwater.org/Modules/ShowDocument.aspx?documentID=8839

Question AP.5: Is there a plan to reconsider on a periodic basis the VA for operational parameters,
governance and allocation shifts, and environmental performance targets?
Scoring: 1 if yes, 0 if noEvidence or Disclosure: Evidence
What this means: Adaptation planning is about precisely that: adapting. An adaptation plan must be able to adjust
to novel conditions over time because climate change is a dynamic series of processes interacting with changing
conditions on the ground and it is impossible to predict precisely how future interactions will play out.
As such, it is important to periodically review the vulnerability assessment to ensure that the information is still
accurate and relevant to the adaptation plan, to conditions on the ground, and the best available science. Evidenceof this could be a management plan that includes a program review timeline and process.
Example from San Francisco, CA: As mentioned in the previous example, the Urban Water Management Plan is
updated every 5 years. The most recent report was produced in 2015. The Sea Level Rise Action Plan also employs acyclical review process for its sea level rise adaptation planning, outlined here: http://default.sfplanning.org/plansand-programs/planning-for-the-city/sea-level-rise/160309_SLRAP_Final_ED.pdf.
Vulnerability assessment feeds into adaptation planning and implementation, monitoring of implementation feeds
back into vulnerability assessment and future adaptation planning. More information about this process can be foundin the project’s executive summary, available here: http://default.sfplanning.org/plans-and-programs/planning-forthe-city/sea-level-rise/160309_SLRAP_Executive_Summary_EDreduced.pdf
Example from the Danube River: The Danube River Basin Management Plan operates on a 6-year cycle to ensurethat its management objectives and activities reflect best practices and any changes to current or future climate
projections. The current plan, covering the period of 2016-2021 is available from the International Commission for
the Protection of the Danube River: www.icpdr.org/main/management-plans-danube-river-basin-published.
