Wavescape Irrigation and Landscaping in Alpine carries CSLB license #834624 and has designed sprinkler and drip-irrigation systems across East County San Diego since 2002. Rain Bird HE-VAN high-efficiency variable-arc nozzles and Hunter MP Rotator heads are standard specifications on retrofit jobs, reducing overspray on properties where Suncoast Pest Management treats adjacent turf and shrub beds. Low-voltage landscape lighting design and installation add LED path lights, uplights, and transformer-fed zone circuits to finished hardscape projects on Alpine's hillside parcels. Drainage system design addresses French-drain and catch-basin layouts for Alpine's sloped lots, rerouting surface runoff away from foundations and retaining walls. Transformer and junction-box wiring for 12-volt landscape circuits runs alongside higher-voltage service panels maintained by Tokai Electric Inc on Arnold Way, separating low-voltage landscape loads from residential mains. Keystone retaining-wall installations use interlocking segmental units with geogrid reinforcement at 24-inch vertical intervals for exposed heights exceeding four feet per San Diego County grading-permit requirements.
