Representative Matters

  • Defended several companies, ranging from family-owned businesses to a publicly traded international corporation, in citizen suit actions under the Clean Water Act (CWA) for alleged stormwater permit violations. Each action required an evaluation of stormwater practices necessary to achieve permit compliance, defensive litigation in federal court, and negotiation of a favorable resolution.
  • Represents a Fortune 500 company in environmental matters involving contaminated sites. Frequently assists client with environmental risk evaluation, advises client in negotiating remediation and settlement agreements, and serves as lead litigation counsel.
  • Represents clients in large, multi-party Superfund allocations. Works closely with experts to position clients for a favorable resolution, whether through a non-judicial allocation process or litigation.
  • Defended a local municipality against a State Environmental Policy Act (SEPA) challenge to the adequacy of its Environmental Impact Statement (EIS). The hearing examiner dismissed several of the challenger’s claims in response to a motion filed by the municipality and ultimately upheld the EIS after the presentation of factual evidence and expert witness testimony at the hearing.
  • Defended a property owner against dozens of construction claims arising out of a six-story, 126-room hotel. Worked closely with the client, project architect, and construction claims consultant to evaluate and value the claims. The matter was resolved in the client’s favor through a series of structured mediations without engaging in costly and prolonged litigation.
  • Defended a local housing authority against construction claims filed by the general contractor seeking millions of dollars in additional compensation for delay, overtime, home office overhead, and differing site conditions. The matter was resolved successfully after a two-week arbitration.
  • Drafted and developed a series of construction contracts for an owner/general contractor, including lump-sum and not-to-exceed contracts and supporting documents (lien release forms, change order forms, payment certification forms, etc.).
  • Represented a corporate client in a breach of contract action arising from defective components purchased from an out-of-state supplier. A key component of the case involved developing expert analysis and testimony to support the causal link between the component’s failure and the supplier’s manufacturing process.
  • Obtained summary judgment dismissal of claims filed under Washington’s Consumer Protection Act (CPA) against a national non-profit thrift store chain.
  • Prosecuted a breach of contract claim in federal court on behalf of a consulting firm against a large, regional hospital for the recovery of sums due on the contract. The matter was settled on terms favorable to the client shortly after the close of discovery.
