Moraga GAD adopts Hetfield Estates plan of control after questions about deep excavations and secondary access
Summary
The GAD board approved Resolution 02‑2026 adopting the Hetfield Estates Plan of Control; board members pressed staff about extensive corrective grading, keyways, on‑site geotechnical oversight and a developer commitment to fund an all‑weather secondary access if access to Sanders Ranch is denied for 10 years.
The Moraga Town Geological Hazard Abatement District board approved Resolution 02‑2026 to adopt the Hetfield Estates Plan of Control, a required document that sets the GAD’s responsibilities for the development’s drainage, retaining structures, monitoring and vegetation management.
The plan — reviewed in coordination with the Town of Moraga Planning Department — lists the GAD’s proposed duties at the Hetfield site, including surface drainage improvements, a bioretention basin, storm‑drain systems, retaining walls, emergency access roads, corrective grading elements (keyways and subdrains) and long‑term vegetation management for fire safety.
During board discussion, members raised detailed questions about the scope of on‑site corrective grading and the stability measures being implemented. A board member asking about deep excavations pressed whether the GAD was providing geotechnical oversight on site; staff and the presenter confirmed active, on‑site geotechnical work. "The deep excavations are what we consider remedial or corrective grading," the presenter said, describing the keyways as intended to prevent horizontal movement.
Board members also asked about a planned secondary egress to Sanders Ranch. Staff said the developer has set aside funds to construct an all‑weather connection if necessary; the plan includes a condition that the developer offer the connection annually for 10 years, and if access is denied throughout that period the funds would transfer to the GAD for use on access improvements.
A motion to adopt the plan was moved, seconded and the chair announced the measure carried.
The plan’s responsibility matrix is large given the site constraints and planned conservation easements; staff noted that per‑unit assessments for Hetfield are likely to be higher than for other parts of the GAD because of the extensive corrective grading and ongoing monitoring obligations.
