The City-Retained Inspection Engineer Private Developer Dual-Service Prohibition Obligation and the Developer-Compensated Public Inspection Dual-Interest Non-Acceptance Constraint both prohibit this arrangement: Firm A cannot adequately represent the city's interests while simultaneously serving private developer clients whose approval interests conflict with rigorous public oversight, and the developer-direct fee-payment structure creates a financial dependency that structurally compromises impartiality regardless of any separate consulting relationship. The Regulated-Party Fee-Payment Public Review Impartiality Non-Compromise Constraint further establishes that the developer's status as fee-payer does not diminish Firm A's obligation of impartiality to the city. Against this, BER 74-2's Small Municipality Public Interest Justification permits a consulting firm to serve as municipal engineer while also performing private work where small municipalities require access to competent engineering services, and the Firm A City Infrastructure Standard Primacy in Inspection obligation could theoretically be honored through procedural safeguards.

The Multi-Hat Dual-Client Adequate Representation Impossibility Recognition Obligation establishes that the cumulative multiplicity of roles, designer, reviewer, and inspector for the same infrastructure, creates a conflict so fundamental that adequate representation of the city's separate interests becomes impossible and is not curable through disclosure or consent. The City-Retained Engineer Self-Design-Review Prohibition Obligation independently prohibits self-review because an inspector who designed the work has a reputational and financial interest in validating prior design decisions rather than identifying deficiencies, eliminating the independent engineering judgment the city's review function is designed to provide. The BER 62-7 County Commission Engineer Self-Review Conflict Prohibition reinforces this by condemning an engineer who passes judgment on behalf of a public client on work the engineer itself performed. Against this, BER 82-4's Review-Recommendation Non-Decision Permissibility framework found that an engineer holding multiple public and private roles did not violate ethics where the engineer only reviewed, recommended, and oversaw plans rather than making final decisions.

The Firm A Public Role Marketing Exploitation Prohibition and the Firm A Competitive Fairness Non-Exploitation of City Contract obligation both prohibit using the city engineer position as a marketing instrument: a publicly conferred advantage may not be weaponized as a commercial differentiator against competitors who lack access to the same publicly conferred position. The Non-Self-Serving Advisory Obligation independently prohibits engineers from structuring their commercial conduct to serve their own financial interests at the expense of the public client's interests. The Fairness in Competition principle establishes that the marketing conduct distorts the competitive market for engineering services because competing firms cannot offer equivalent cost savings without holding the city contract. Even under the most permissive reading of BER 74-2, which tolerates dual municipal and private roles in small municipalities, no precedent sanctions affirmative exploitation of a public role as a private marketing instrument.

The Non-Self-Serving Advisory Obligation prohibits engineers in public service from using their public position for private commercial advantage. The Fairness in Competition principle requires that competitive advantages in the engineering market derive from technical capability and efficiency rather than from publicly conferred regulatory authority. The Public Position Marketing Exploitation Prohibition independently condemns the conversion of a public appointment into a sales proposition, separate from any structural conflict-of-interest analysis. Even the most permissive reading of BER 74-2, which tolerates dual municipal and private roles in small municipalities, does not sanction affirmative exploitation of a public role as a private marketing instrument.

The Disclosure Insufficiency for Structural Conflict principle holds that when divided loyalty inheres in the role relationship itself rather than arising from particular circumstances, no disclosure or consent mechanism can dissolve the conflict because the city's consent would mean only that it knowingly accepted a compromised inspection regime, not that inspection would in fact be uncompromised. The Divided Loyalty Irreconcilability principle from BER 62-7 holds that simultaneous conflicting loyalties cannot be reconciled by procedural means. The Abstention-Based Conflict Mitigation Permissibility Principle from BER 75-7 supports the view that disclosure paired with recusal from discrete conflicted decisions can be sufficient where roles are separable and substitutable decision-makers exist. The Compensating-Party–Benefiting-Party Misalignment Conflict Principle identifies that the city's meaningful informed consent is structurally limited by its dependence on Firm A.
