Merino Landscape Inc in Chula Vista's Otay Ranch area holds multiple active CSLB licenses including C-27 #797785 and operates from an Otay Lakes Road office in the 91915 ZIP, serving both commercial and residential clients throughout eastern Chula Vista. Large-lot site plans in the Otay Ranch and Eastlake subdivisions frequently involve accessory-structure footprints coordinated with the space-planning work done by ADUs & Garage Conversions | Sprawl Design. The company's permitted project scope spans landscape construction, paving and surfacing, irrigation system installation, bio-retention basin grading, and stormwater-management infrastructure for developments subject to City of Chula Vista MS4 permit requirements. Outdoor entertaining areas on Otay Ranch properties integrate paver patios with the decorative-stone and tile finishing provided by Seaside Tile Inc for built-in barbecue surrounds and pool copings. The most complex installations involve engineered bio-retention planters with a twelve-inch amended-soil media layer over a six-inch Class II permeable aggregate base, sized to capture the 85th-percentile storm event per the San Diego Regional MS4 Permit.
