Step 4: Review

Hold paramount the safety, health, and welfare of the public.

Act for each employer or client as faithful agents or trustees.

Engineers shall be objective and truthful in professional reports, statements, or testimony. They shall include all relevant and pertinent information in such reports, statements, or testimony, which should bear the date indicating when it was current.

Engineers shall not offer, give, solicit, or receive, either directly or indirectly, any contribution to influence the award of a contract by public authority, or which may be reasonably construed by the public as having the effect or intent of influencing the awarding of a contract. They shall not offer any gift or other valuable consideration in order to secure work. They shall not pay a commission, percentage, or brokerage fee in order to secure work, except to a bona fide employee or bona fide established commercial or marketing agencies retained by them.

Engineers shall advise their clients or employers when they believe a project will not be successful.

Engineers shall treat all persons with dignity, respect, fairness and without discrimination.

Engineers are encouraged to participate in civic affairs; career guidance for youths; and work for the advancement of the safety, health, and well-being of their community.

Engineers are encouraged to adhere to the principles of sustainable development1in order to protect the environment for future generations.Footnote 1"Sustainable development" is the challenge of meeting human needs for natural resources, industrial products, energy, food, transportation, shelter, and effective waste management while conserving and protecting environmental quality and the natural resource base essential for future development.

Cited as an analogous situation involving disclosure of tradeoffs between a traditional (fossil-fuel) and sustainable (solar) system, establishing that engineers must include all relevant information, including risks like reduced reliability and additional costs to mitigate that risk.

Cited to support the principle that engineers should proactively suggest sustainable alternatives to clients, harmonizing the duty to be a faithful agent/trustee with the encouragement to adhere to sustainable development principles, and that refusing to perform the task is not an acceptable alternative.

Cited to illustrate how engineers should think creatively beyond binary options when addressing disproportionate impacts on communities, drawing a parallel to the flood control case's underserved community issue.

Mentioned alongside Case 73-9 as additional precedent discussing highway routing and disparate impact, supporting the general takeaway that there is no single correct answer and engineers should be creative.

Mentioned alongside Case 65-9 as additional precedent discussing highway routing and disparate impact, supporting the general takeaway that there is no single correct answer and engineers should be creative.

Engineer K should present both approaches to the City if Engineer K believes both are viable solutions.

Because Engineer K has entered into a contract to design the new flood water control system, Engineer K has an ethical obligation to act as a faithful agent or trustee. Engineer K is ethically obligated to fulfill their contractual obligations to the City and continue to design the Traditional Approach as approved by the City.

The Board's disclosure conclusion should be read as requiring not merely presentation of two design options, but specific and prominent disclosure of the disparate flood-diversion risk to the underserved community. Because this risk implicates the paramount duty to protect public safety, health, and welfare, it functions as a distinct and heightened disclosure obligation that sits above ordinary cost/benefit comparison of design alternatives, and Engineer K's presentation should be evaluated separately for whether it gave this risk the prominence the paramount duty demands, not simply whether both approaches were mentioned.

The Board's faithful agent conclusion should be understood as conditional rather than absolute: Engineer K's obligation to continue implementing the Traditional Approach depends on the City's approval having been made with full knowledge of the disparate impact risk. If new information later emerges that materially changes the risk profile to the underserved community, or if the low-probability event begins to materialize, the faithful agent duty would not shield Engineer K from a renewed obligation to advise the City under III.1.b. and to reassess whether continued implementation still satisfies the paramount duty to public welfare.

Beyond simply presenting both approaches, Engineer K's faithful agent duty and the encouragement to promote sustainable development together suggest an ethical opportunity, though not a strict obligation, to propose mitigation measures or a hybrid design that could reduce the disparate impact within the Traditional Approach framework. The Board's conclusions do not foreclose this option, and a more complete analysis recognizes that faithful agency includes bringing forward creative solutions that reconcile client priorities of cost and speed with public welfare and fairness concerns, rather than treating the choice as strictly binary between the two original alternatives.

Regarding Q101 and Q304: Once the City, fully informed, approved the Traditional Approach and declined to mitigate the disparate flood-diversion risk, Engineer K's paramount duty under I.1. to protect public welfare does not evaporate but narrows in scope. Engineer K retains a continuing obligation to document the risk, ensure it is reflected in design records, and remain alert to any material change in circumstances (e.g., new data increasing the probability of breach) that would trigger a renewed duty to advise the City under III.1.b. However, absent such change, Engineer K is not obligated to unilaterally refuse to implement the City's lawful, informed decision, since the faithful agent duty under I.4. governs implementation once disclosure and advisement duties have been discharged.

Regarding Q102: Engineer K's disclosure of the disparate impact risk during the City Council meeting satisfies the affirmative duty under I.1. and III.1.b. to advise the client of foreseeable harms, because the disclosure was made before the City's final decision, included the low-probability/high-volume conditions, and identified the affected population. The paramount public welfare duty in this context is a duty of disclosure and advisement to the responsible public decision-making body, not an independent veto power over the client's informed policy choice; thus no further affirmative action (such as refusing to proceed) was ethically required at the disclosure stage.

Regarding Q103: While Engineer K was not ethically required to unilaterally develop a hybrid mitigated design before presenting the two approaches, the encouragement toward sustainable development (III.2.d.) and the dignity and fairness obligation to the underserved community (III.1.f.) suggest that proposing a low-cost mitigation add-on to the Traditional Approach (e.g., localized floodwater diversion controls) would have been a professionally responsible enhancement to the disclosure, even though it was not a strict ethical mandate given time and the two-option scope the City had approved for stakeholder review.

Regarding Q201: The tension between faithful agency (I.4.) and the welfare of the underserved community (I.1., III.1.f.) is resolved procedurally rather than substantively in this case: Engineer K discharges the public welfare duty by ensuring the City, as the accountable public body, receives complete and truthful information about the disparate risk before deciding. Once that disclosure occurs and the City makes an informed, lawful decision, the faithful agent duty resumes primacy for implementation, because engineers are not empowered to override democratically accountable client decisions absent an imminent, undisclosed, or illegal danger.

Regarding Q301: From a deontological standpoint, Engineer K fulfilled the duty of complete and truthful disclosure under II.3.a. and the complete reporting duty by presenting both approaches with their respective risks and benefits, including the disparate impact risk, notwithstanding a personal preference for the Sustainable Approach. The duty of truthful disclosure is satisfied by comprehensiveness and objectivity of information provided, not by the engineer's subjective preference being suppressed or promoted; therefore Engineer K's personal belief does not create a competing duty requiring one-sided presentation.

Regarding Q401: If Engineer K had not discovered the disparate impact risk prior to the Council meeting, the Board's conclusion that presenting both approaches satisfies disclosure obligations would still hold as to the design alternatives themselves, but a new ethical question would arise regarding due diligence: the paramount public welfare duty under I.1. arguably requires engineers to proactively investigate foreseeable risks such as differential flood impacts on vulnerable populations before finalizing recommendations, meaning non-discovery due to inadequate analysis could itself constitute an ethical lapse distinct from the disclosure question actually addressed by the Board.

Regarding Q402: Had the City approved the Traditional Approach without ever being informed of the disparate impact risk, the Board's conclusion that Engineer K must act as a faithful agent and continue design work would not straightforwardly apply, because faithful agency presupposes that the client's decision was adequately informed. In that counterfactual scenario, Engineer K's overriding duty under I.1. and III.1.b. to disclose known material risks would take precedence over continued implementation until the City was properly informed, meaning continued work without disclosure could itself violate the Code.

Regarding Q403: The Board's recommendation that Engineer K present both viable approaches would apply with equal or greater force if Engineer K had no personal preference, since the underlying rationale is the engineer's objectivity and completeness obligation under II.3.a. rather than a corrective measure against bias. The presence of a personal preference in the actual case simply heightens the importance of the objectivity duty, but the disclosure obligation itself is preference-independent and would exist regardless.

The tension between Faithful Agent Loyalty to the City and Public Welfare of the Underserved Community was resolved procedurally rather than substantively: Engineer K's duty was satisfied by complete and objective disclosure of the disparate risk to decision-makers, not by requiring Engineer K to refuse implementation or unilaterally alter the design once the City, as the accountable public body, knowingly accepted the risk. This suggests that under the Code, the paramount public welfare obligation (I.1.) is discharged at the point of full and honest disclosure to a legitimate public authority, after which the faithful agent duty (I.4.) governs continued professional conduct, even though the underlying risk to the community remains unmitigated.

Objective Truthful Reporting on Design and Complete Disclosure of Design Alternatives functioned as constraints that neutralized Engineer K's personal preference for the Sustainable Approach: rather than creating a conflict, the objectivity duty required Engineer K to bracket personal judgment and present both technically viable alternatives on their merits. This shows that Sustainable Development Adherence Encouragement (an aspirational, 'encouraged' provision under III.2.d.) cannot override the mandatory disclosure and objectivity obligations under II.3.a., establishing a hierarchy in which encouraged conduct principles yield to core reporting duties when they might otherwise bias professional judgment.

The case illustrates an unresolved gap between procedural fairness and substantive fairness: Dignity and Fairness to Underserved Community was honored in the sense that the community's risk was identified and disclosed, but the principle was not given weight sufficient to alter the outcome once cost and schedule considerations dominated the City's deliberation. This indicates that the Code, as currently structured, does not clearly establish an affirmative duty for engineers to advocate beyond disclosure for vulnerable populations who lack direct decision-making power, leaving a normative gap between the paramount welfare clause (I.1.) and its practical enforcement mechanism.

Engineer K personally believes the Sustainable Approach is better. Should Engineer K have only presented information about the Sustainable Approach?

Does Engineer K have any ethical obligations after the City approves the Traditional Approach?

Given that Engineer K discovered a disparate flood-diversion risk to an underserved community, does Engineer K have an ongoing obligation to advocate for mitigation measures even after the City approved the Traditional Approach without addressing that risk?

Did Engineer K's disclosure of the disparate impact risk to the underserved community meet the threshold required by the paramount duty to protect public safety, health, and welfare, or was more affirmative action required before proceeding with design?

Should Engineer K have proposed a hybrid or mitigated version of the Traditional Approach that addressed the disparate impact on the underserved community, rather than presenting only the two original alternatives?

Does the City's decision to accept a low-probability but high-impact risk to an underserved community, driven by cost and schedule concerns, raise separate ethical or documentation obligations for Engineer K distinct from the general duty to follow client direction?

How should Engineer K balance the duty to act as a faithful agent of the City against the paramount obligation to protect the welfare of the underserved community affected by the Traditional Approach?

Does Engineer K's personal belief that the Sustainable Approach better fulfills sustainability principles conflict with the duty to provide complete, objective disclosure of both design alternatives?

How should the encouragement to adhere to sustainable development principles be weighed against the City's authority to approve a less sustainable but lower-cost, faster Traditional Approach?

Does the principle of dignity and fairness to the underserved community conflict with Engineer K's obligation to defer to the City's final decision on the design approach?

From a deontological perspective, did Engineer K fulfill their duty of complete and truthful disclosure by presenting both the Traditional and Sustainable Approaches despite a personal preference for the latter?

From a consequentialist perspective, does the City's informed decision to accept the low-probability risk to the underserved community justify Engineer K's continued participation in implementing the Traditional Approach?

Did Engineer K act with professional integrity by setting aside personal belief in the Sustainable Approach's superiority to give the City a balanced presentation of both options?

From a deontological perspective, did Engineer K's duty to protect public welfare require any further action toward the underserved community once the City approved the Traditional Approach despite the known disparate impact risk?

If Engineer K had not discovered the disparate impact risk on the underserved community before the City Council meeting, would the Board still conclude that Engineer K satisfied the duty of complete disclosure by presenting both approaches?

If the City had approved the Traditional Approach without ever being informed of the disparate impact risk to the underserved community, would the Board still find that Engineer K's obligation to act as a faithful agent requires continuing implementation?

If Engineer K had no personal preference between the two approaches, would the Board's conclusion that Engineer K should present both viable alternatives still apply with the same force?

If the City had directed Engineer K to skip stakeholder meetings entirely, would the Board still conclude that Engineer K adequately fulfilled the duty to present complete information on both design alternatives?

Because this decision follows directly from Engineer K's full disclosure of the disparate flooding impact, its lack of any fulfilling or violating edge underscores that the ethical burden shifted entirely to City leadership, whose approval nonetheless perpetuates the mitigation risk and drives implementation forward regardless of the equity concerns raised.

By fulfilling the objective and truthful reporting obligation and the duty to include all pertinent information, and by being guided by objectivity, dignity, and public welfare, this disclosure ensured that the disparate impact discovered in design development was transparently passed to the City before the approval decision, even though it could not itself prevent the City from later accepting the residual risk.

Guided by public health, safety, and welfare, Engineer K's acceptance of the engagement in response to severe flooding escalation set in motion the entire causal chain, meaning the safety-oriented justification for taking on the project is what gives ethical weight to everything that follows, including the eventual discovery of disparate impacts.

This action fulfills the duty to advise the client on project success and is guided by sustainable development and public safety, but because it directly causes the discovery of a disparate impact, it shows how a professionally sound design process can still surface serious equity problems that must be disclosed rather than concealed.

Facilitated under the guidance of dignity, respect, and fairness toward all persons, this meeting's role in producing a stakeholder opinion split shows that even a fair and respectful process can expose real disagreement among affected parties, foreshadowing the equity tensions that the later disparate impact discovery would formalize.

Because Implementation Continuation follows directly from the City's Municipal Approval Decision made after Full Information Disclosure, Engineer K's proceeding fulfills the Faithful Agent or Trustee Obligation to carry out the client's informed decision, even though it leaves the Mitigation Risk Persistence unresolved, so the action is guided by Public Health, Safety, and Welfare concerns that were satisfied through disclosure rather than through the engineering choice itself.

The question arises because Engineer K's personal belief in one design's superiority creates tension between the professional obligation to advocate for perceived public benefit and the obligation to serve as a neutral, complete informant so the City can exercise its own decision-making authority.

This question arises because approval by a public client does not automatically discharge an engineer's independent obligations to public safety and equitable treatment when a known, unresolved risk to an underserved community remains after the decision.

The question arises because the disparate impact discovery created a duty of ongoing concern for the underserved community's welfare that was not resolved by the City's approval of an alternative lacking mitigation, leaving unclear whether Engineer K's professional role obligations terminate at disclosure or persist through implementation.

The question arises because the paramount public welfare duty is open ended regarding what counts as sufficient action once a risk is known, so disclosure satisfies a minimal reporting warrant but may fall short of a more demanding protective warrant.

This question arises because the disparate impact discovery reveals a gap between what was technically disclosed and what could have been proactively designed, creating tension between an engineer's role as a neutral reporter of alternatives and as an active protector of public welfare and fairness.

The question arises because the City's decision does not eliminate ambiguity about whether Engineer K's professional and ethical duties are fully discharged by informing the client, or whether the disproportionate risk to an underserved community creates a distinct, non-delegable obligation for the engineer.

The question arises because the same set of facts, a disparate impact on an underserved community combined with a pending City decision, simultaneously activates the engineer's loyalty duty to the client and the paramount duty to protect public welfare, and the NSPE Code does not specify which obligation controls when they diverge.

The question arises because Engineer K's personal belief in sustainability values intersects with a professional obligation to remain neutral, and the stakeholder split and disparate impact findings heighten the stakes of how that belief might shape the disclosure to the City.

The question arises because encouragement toward sustainable development is only advisory while municipal approval authority is decisive, creating uncertainty over how much weight the engineer's sustainability recommendation should carry against the City's legitimate discretion.

The question arises because the engineer's technical finding of disparate flood risk to a vulnerable population creates a moral claim that competes with the professional norm of deferring to the client's final authority over engineering design choices.

The question arises because Engineer K's personal preference for the Sustainable Approach creates suspicion about whether the disclosure was truly neutral, even though the formal duty to present both approaches was technically performed.

The question arises because a consequentialist framing invites weighing aggregate risk against client autonomy, but the City's decision to accept risk on behalf of a community that did not consent creates a direct clash between deferential and welfare-protective professional obligations.

The question arises because Engineer K had to balance faithful agency and objective reporting against a personal belief and a professional duty to encourage sustainable outcomes, and the disparate impact discovery raises doubt about whether neutral presentation was sufficient given the stakes for the underserved community.

The question arises because Engineer K fulfilled procedural obligations of disclosure and faithful agency, yet the City's decision left a known risk unaddressed for a vulnerable population, forcing a deontological inquiry into whether duty extends beyond procedural compliance into substantive outcomes.

The question arises because the timing of Engineer K's discovery of the disparate impact risk determines whether the applicable warrant is a general duty to disclose alternatives or a heightened duty to disclose specific harms to an underserved community, and the Board's judgment about satisfaction of duty hinges on which warrant governs.

The question arises because the hypothetical removes the City's awareness of disparate impact, stripping the approval of the informed basis normally required to justify unquestioning agent loyalty, thus forcing a reexamination of whether faithful agency obligations survive when the underlying decision was uninformed.

The question emerges because the Board's original conclusion assumed or implied that Engineer K's duty to present alternatives was motivated in part by managing personal preference amid a divided stakeholder debate, so removing that preference exposes an ambiguity about whether the disclosure warrant is agent-centered or welfare-centered.

This question arises because the case bundles two distinct obligations, disclosing technical alternatives and engaging the public, into one narrative, so removing the City-directed stakeholder process isolates whether Engineer K's duty to present complete information depends on that public engagement step or can be satisfied through direct client reporting alone.

Given that Engineer K held a personal preference but regarded both approaches as viable, the board concluded that professional objectivity required presenting both rather than filtering the City's options through personal belief.

Given the existence of a binding design contract and a City approval that followed presentation of alternatives, the board concluded that Engineer K's ethical obligation shifted to faithful implementation of the client's chosen design.

Because the risk discovered was not generic but fell disproportionately on an underserved community, the board reframed the original disclosure conclusion as demanding prominent, specific communication of that disparate risk rather than mere mention of two options.

Given that the faithful agent duty in Conclusion_2 rested on an implicit assumption of informed City consent, the board clarified that this duty is conditional and would yield to a renewed advisory obligation under III.1.b if the risk picture materially worsens.

Because sustainability provisions are worded as encouragement rather than strict obligation, and because a hybrid design was plausible without abandoning the Traditional Approach, the board concluded that proposing mitigation was an ethical opportunity for Engineer K rather than a binding requirement.

Given that the City was fully informed and knowingly declined mitigation, the board concluded Engineer K's paramount duty survives only as a narrowed obligation to document and monitor, not as a mandate to unilaterally resist implementation, because the faithful agent duty resumes primacy absent a triggering change in facts.

Given that Engineer K disclosed the specific risk parameters and affected community before the City voted, the board concluded the disclosure threshold for public welfare was met, because the duty at this stage is one of advisement rather than override authority.

Given that Engineer K worked within a City-defined two-option scope and limited time, the board concluded that proposing a mitigated hybrid design would have been a professionally responsible enhancement but not a strict ethical requirement, because III.2.d. and III.1.f. operate as encouragements rather than mandates in this context.

Given that the City received full and truthful information and made a lawful, accountable decision, the board concluded the faithful agent duty resumes primacy for implementation, because engineers lack authority to override informed democratic decisions absent imminent or undisclosed illegality.

Given that Engineer K presented comprehensive and objective information on both approaches including the disparate impact risk, the board concluded the duty of truthful disclosure was fulfilled, because personal preference does not create a competing obligation once objectivity and completeness are maintained.

Given that Engineer K in the actual case had already discovered the risk before advising the City, the Board's disclosure-adequacy conclusion presupposed that discovery; had discovery not occurred, the Board reasons a distinct question of due-diligence failure under I.1. would arise rather than simply reaffirming the disclosure conclusion.

Because the actual case involved the City approving the Traditional Approach only after being told of the risk, the Board's faithful-agent conclusion depended on that informed approval; absent such disclosure, the Board reasons the overriding I.1. and III.1.b. disclosure duty would require Engineer K to inform the City before proceeding rather than to simply continue design work.

Since the Board grounded the disclosure recommendation in II.3.a. objectivity rather than in neutralizing Engineer K's actual preference, it reasons the same disclosure obligation would apply, and apply with equal force, even in a hypothetical case where Engineer K had no preference at all.

Because Engineer K disclosed the disparate risk fully and the City, as the publicly accountable decision-maker, knowingly chose to accept it for cost and schedule reasons, the Board concludes the paramount welfare duty was satisfied at disclosure, after which faithful agency permits (and requires) continued implementation despite the community's risk remaining unaddressed.

Given that Engineer K's preference for the Sustainable Approach was personal rather than grounded in the Traditional Approach's technical unviability, the Board reasons the mandatory II.3.a. objectivity and disclosure duties required presenting both alternatives on their merits, subordinating the encouraged III.2.d. sustainability principle to those core reporting obligations.

Because Engineer K disclosed the disparate risk and the City nonetheless approved the Traditional Approach after weighing cost and schedule, the board concluded that procedural fairness was met but substantive fairness was not assured, exposing a gap in how the Code's paramount welfare principle is operationalized for populations without direct decision-making power.

Should Engineer K present both the Traditional Approach and the Sustainable Approach to the City with complete, objective information, or advocate primarily for the Sustainable Approach based on personal belief?

Should Engineer K specifically and prominently disclose the disparate flood-diversion risk to the underserved community, and additionally propose a mitigation option, or fold that risk into the general comparison of the two alternatives?

After the City's informed approval of the Traditional Approach, should Engineer K continue implementing the design while documenting and monitoring the disparate risk, or refuse to proceed until mitigation is added, or simply continue without further action?

Should Engineer K continue implementing the Traditional Approach as directed by the City, or refuse to proceed until further mitigation is adopted for the underserved community?

Should Engineer K present only the two original design alternatives, or proactively develop and propose a hybrid mitigated design addressing the disparate impact before presenting options to the City?
