Coastal SAGE Landscape Architecture operates from 2nd Street in Encinitas's Old Encinitas district as a woman-owned, SBA-certified Small Disadvantaged Business firm established in 1997. The principal holds PLA and FASLA designations — Fellow of the American Society of Landscape Architects — and coordinates indoor-outdoor spatial continuity with designers such as JY Design Interiors on residential commissions. Specialty practice areas include rainwater harvesting with underground cistern design, greywater irrigation systems, and permaculture-based planting plans aligned with California's Model Water Efficient Landscape Ordinance. Native and climate-adapted plant specifications draw from coastal nurseries like Barrels & Branches for regionally appropriate species suited to the Self Realization Fellowship corridor. Highest-tier projects integrate bio-swale stormwater management, rain-garden infiltration basins, and reclaimed-water irrigation networks across multi-parcel community developments requiring CEQA environmental review.
