Environmental risk
KOW guidance on Phase I Environmental Site Assessments, historical property uses, recognized environmental conditions, and next-step diligence.
Why this topic matters
Technical context for a better-informed decision.
Environmental due diligence organizes current and historical information so lenders, purchasers, owners, and counsel can understand which conditions may matter to a real estate decision. Timing, access, records, interviews, site history, and data gaps all affect the usefulness of the work.
KOW’s environmental-risk coverage explains assessment scope and process in practical terms. It does not replace site-specific professional judgment, legal advice, or additional investigation when the available evidence indicates that more work may be appropriate.
