Hambden Hills

Audit Analysis

Hambden Hills is a 40-year urban tree preservation project under the City Forest Credits standard with VVB-confirmed additionality and a 10% buffer pool, but it relies on a project-specific baseline, lacks a quantified leakage deduction in the available record, and shows a minor discrepancy between the PDD and validation ERR figures. The project is structurally sound for a CFC tree-preservation credit but sits in a less transparent registry with several monitoring and safeguards details not stated in the extracted documents.

Project Description

Red Flags

• ⚠PDD (2025-09-10) lists 6,599 total ERR while the validation report (2026-01-30) and verification report both state 5,939 — a ~9% downward revision that is not explicitly explained in the available documents.
• ⚠The verification report (2026-01-28) marks reversal events as 'not addressed' while the validation report (2026-01-30) states 'none reported'; the 10% buffer pool exists but the verification report does not confirm its adequacy or the status of the 660 credits already contributed to the Reversal Pool.
• ⚠Leakage is described as 'quantified' in the justification field, yet no specific deduction percentage appears in any extracted document, leaving the actual magnitude of the leakage adjustment unverifiable.
