Established in 2010 and operating under CSLB C-27 license #1032433, Cabanas Landscape is the irrigation-and-sustainable-landscape operation run by Sebastian Cabanas from Narragansett Avenue in OB. Drip-system design and irrigation diagnostics make up the core service line, with mainline repairs and backflow-preventer replacements frequently handed off to Sunset Cliffs Plumbing when a project crosses the meter side of the property water supply. Sebastian's San Diego Mesa College background and field range span irrigation refreshes at La Jolla residences and water-stressed vineyard work in Ramona, which informs the drought-adapted plant palettes used on OB projects. Water-use calibration — matching emitter flow to plant evapotranspiration rates and scheduling zones by microclimate — is the precision work that trims MWD tier-two water pricing and prevents foundation erosion on sloped OB lots. Hardscape scopes that exceed C-27 landscape authority, such as ADU footprint pours and attached patio construction, tie in through general-construction crews at Ohana Builders during larger whole-yard redesigns. The most technical projects are complete front-and-rear-yard conversions on sloped Ocean Beach lots where graywater capture, smart controllers, and California-native plant palettes have to be engineered together from a single master plan.
