Established in 1992, Landsmith Landscape Construction operates from 7710 Marie Ave in La Mesa with CSLB license #318738 covering C-27 Landscaping classification and a scope that includes hydroseeding, hardscape construction, irrigation installation, and concrete flatwork. Grading and drainage work routes surface water away from the building envelope, directing roof-gutter downspout discharge into catch basins that complement the gutter systems installed by roofing contractors like Coastal Crest Roofing. The sole-proprietorship structure under owner Juan Manuel Banales consolidates landscape design, plant procurement, and construction under a single point of contact for residential and commercial projects in the 91941 and 91942 ZIPs. Irrigation rough-in for new landscape installations routes Schedule 40 PVC mainline from the meter to zone valves, a pressurized feed that requires proper backflow prevention devices tested by licensed plumbers like Earl W Fite & Sons Plumbing Inc. Large-scale hydroseeding projects apply a bonded fiber matrix mulch at 3,000 pounds per acre to stabilize cut-and-fill slopes exceeding 2:1 grade ratios before permanent root establishment.
