Drainage / stormwater maintenance at 322 Monte Vista Avenue I am reporting on behalf of Monte Vista Residences, LLC, owner of the immediately adjoining property at 312 Monte Vista Avenue. Please inspect drainage conditions at 322 Monte Vista, specifically the roof/downspout drainage, subterranean parking-area drains, underground stormwater lines, and any sump or collection system. We have observed roof runoff directed toward the parking area, standing water, and physically blocked drains. The parking structure adjoins our property. The photographs supplied with our evidence packet are historical: capture metadata dates the standing-water photograph to December 13, 2022 and the context photographs to March 1, 2022. We request an inspection to establish the present condition and discharge destination. At 312, we continue to experience intermittent basement water intrusion from below despite foundation, gutter, downspout, and drainage work. Contractors who evaluated the conditions have told us that 322's drainage is a likely source or material contributing source. This is our report of their assessments; we are not asserting that causation has been scientifically established. Our December 6, 2022 geotechnical report for the proposed project at 312 recommends controlled roof drainage and addresses water accumulating behind below-grade walls. It provides site context, rather than a diagnosis of 322. Our June 2022 survey is also supplied for context; it does not establish the garage-floor elevation at 322. I first contacted management on September 30, 2026 and have since sent eight follow-ups and inquiries. As of November 11, 2026, no confirmation of corrective work or corrective plan has been provided to us. Oakland Building Maintenance Code section 15.08.230(L) addresses lot drainage, including parking areas, and prevention of surface-water ponding, subject to its occupancy exception. Oakland Building Code section 1815B.1, within OMC 15.04.3.2075, addresses concentrated stormwater flow onto neighboring property, subject to the section's exceptions and approved methods. Please determine whether the drainage is maintained, conveys water to an approved facility, or requires corrective work. This request concerns private-property stormwater drainage; it does not allege a sanitary-sewage discharge.
