Dugmore Design Studio in Encinitas's Olivenhain community holds California Registered Landscape Architect license #3365, providing design services from concept development through construction documentation since 1994. Indoor-outdoor spatial flow on Olivenhain estate lots frequently aligns with interior planning from firms like Casa Contour Interior Design to unify material palettes across thresholds. Both principals hold Master of Landscape Architecture degrees — one from the University of Pennsylvania and one from California State Polytechnic University at Pomona — with combined prior experience at the San Diego County Planning Department. Irrigation design for large-acreage Olivenhain properties requires backflow-preventer installation and mainline routing through plumbing contractors such as Yogi's Plumbing & Drain Service for municipal cross-connection compliance. Construction document packages include grading plans, planting plans, and irrigation hydraulic calculations scaled for residential parcels exceeding one acre along Rancho Santa Fe Road.
