Women-owned landscape design-build practice L Watson Design & Co works from Arroyo Drive in Mission Hills on drought-tolerant native gardens, edible beds, hardscape, and rooftop decks. Larger sloped lots with grading and stormwater requirements coordinate with landscape architects such as GroundLevel Landscape Architecture for stamped plans ahead of permit intake. Project types include pond construction, pergola and patio design, and organic vegetable gardens built to client specifications. Low-voltage path and accent lighting installs coordinate with electricians such as CET Electric for transformer placement and trenching around root zones. Material palettes favor decomposed granite, Santa Barbara sandstone flagstone, Corten steel edging, and California native perennials selected for the 92103 microclimate. Full backyard overhauls integrate pond water features, pollinator plantings, and mid-century-modern hardscape into single-concept design-build packages on hillside Mission Hills lots.
