Neighbors Warn of Slide Zone; Staff Says Geologist Must Sign Off Before Permits

Neighbors said the geotechnical report is incomplete for a state-mapped landslide zone; staff said a supplemental report must satisfy the county peer-review geologist before any permit.

Attorney Challenges CEQA Exemption for Kensington Variance; Commissioners Unpersuaded

Neighbors and Owners Clash Over Who Measured Century-Old Culvert

Appellants say the culvert's size was never reliably established and engineering markups are inconsistent; the owners say they measured and documented it in good faith.

Why it matters: The dispute turned on whether the culvert size must be fixed now or can wait for building permit review, which determined whether a rehearing was warranted.

Commissioners Say Last-Minute Document Dumps Leave Them Underprepared

Commissioners complained that multi-page submissions arrive hours before hearings; staff said state law bars blocking them and the commission may continue items.
