San Marino Landscape Design | Huntington-Tier DRB 2026
Landscape design in San Marino is composition at the level the Huntington Library and Botanical Gardens set as the neighborhood standard. The Design Review Board is mandatory and rigorous, the heritage trees on most San Marino estates are individually protected and often older than the houses, and the client expects formal garden craft of a kind that only a handful of LA-area firms still execute properly. NP Line Design has drawn San Gabriel Valley estate landscapes since 2016 and runs build as a CSLB licensed GC since 2023. We prepare architectural-grade DRB submissions, coordinate certified arborists on heritage trees, and design and build formal gardens at Huntington-adjacent tier.

San Marino DRB is mandatory for exterior changes including landscape. The board expects architectural-grade landscape submission: schematic and design development drawings, planting plans with mature heights drawn at 10, 15, and 20 years, materials boards with physical hardscape samples, elevation studies in context, hardscape detail drawings, and a written design narrative. Our last eight 91108 landscape submittals cleared DRB on first or second review.Heritage trees and formal garden composition
Most San Marino estates have heritage trees that are individually protected and often older than the residence. We coordinate with certified arborists on tree preservation, design around root protection zones, and integrate the trees as anchors in the formal garden composition. The Huntington Library and Botanical Gardens set the local standard for formal garden craft (parterre design, allee composition, hand-pruned hedges, ornamental fountains, formal water features); we design and build at that tier where the client wants it.Landscape Design Questions Homeowners Ask About Landscape Design in San Marino
