Studio West Landscape Architecture & Planning is a women-owned landscape architecture firm in San Carlos, San Diego, operating from 7185 Navajo Road, Suite A, in the 92119 ZIP. Principal Marian Marum founded the practice in 1979 as Marum Partnership and has maintained a continuous focus on sustainable, water-conserving landscape design across more than four decades of projects spanning military facilities, public infrastructure, civic spaces, healthcare campuses, corporate properties, and educational institutions. Building architects specifying site plans for institutional and commercial projects coordinate grading, drainage, and landscape integration with landscape architects early in the design-development process, and Schall Architects in Allied Gardens works with landscape firms on the site-plan entitlements, setback calculations, and stormwater-management details that San Diego's Development Services Department reviews during permit approval. Navajo Road forms the commercial spine of San Carlos, running between the Lake Murray Boulevard intersection and the Cowles Mountain trailhead area, and the Suite A office sits within the neighborhood's small-business corridor serving the surrounding residential grid of 1970s and 1980s single-family homes. The firm's public-sector portfolio includes landscape master plans, environmental impact analysis support, ADA-compliant pathway and plaza design, and construction-document packages that meet federal, state, and municipal procurement standards — a credential set that separates licensed landscape architects from landscape designers and contractors who operate without the state-licensure requirement. Irrigation design for large-scale landscape installations requires hydraulic calculations, backflow-preventer sizing, and mainline routing that intersects with the property's plumbing infrastructure, and American Plumbing Group in Grantville handles the supply-line connections, meter upgrades, and backflow-device installations that feed the irrigation systems Studio West specifies in its construction documents. San Carlos sits between Lake Murray to the south and the Cowles Mountain ridgeline to the north, and the 92119 ZIP's hillside topography and fire-risk vegetation zones create design constraints that landscape architects address through defensible-space grading, native-plant palettes rated for the wildland-urban interface, and stormwater-retention features that satisfy both the city's municipal storm-water permit and the California Environmental Quality Act. The practice accepts projects across San Diego County, with the Navajo Road base keeping the shortest response times for San Carlos, Del Cerro, Allied Gardens, and the eastern College Area corridor.
