Underground utility locating protects your commercial project in Sunnyvale, CA before any digging starts. Coastline Utility Inc. can locate and map gas lines, water supply lines, electrical conduits, and fiber optic cables across the city. We work on Sunnyvale’s residential streets and Silicon Valley commercial sites every week. A single utility strike can stop a project for days and cost tens of thousands of dollars in repairs and fines. Our team brings precision equipment and California-licensed expertise to every job. We handle backyard pool digs in Cherry Chase and heavy civil construction near Moffett Park. You get a clear utility map, fast turnaround, and full confidence before excavation begins.

Sunnyvale Construction Projects Require Precise Underground Utility Locating

Sunnyvale sits on dense layers of public utilities built up since the 1950s. Water supply lines, gas lines, sewer mains, storm drain pipes, and fiber optic cables crisscross beneath every block. New tech-campus builds, road work, and home remodels add fresh utility installations each year. California Government Code Section 4216 requires every excavator to mark and verify underground utilities before any dig. USA North 811 marks public lines only — public utility locators do not cover private services on your property. Coastline Utility closes that gap. We deliver private utility locating that meets Cal-OSHA safety standards and protects every utility trenching project from first cut to final backfill.

Utility Locating Services Coastline Provides in Sunnyvale

Coastline provides a full set of utility locating services for Sunnyvale contractors, property managers, and homeowners. Each service pairs precision equipment with experienced field technicians. You get accurate utility maps, photo documentation, and direct contact with the technician who walked your site.

• Private Utility Locating and Utility Mapping: Our utility locators mark every private line on your property. You receive color-coded surface marks and a full utility map before work begins.
• CCTV Pipe Inspection: High-resolution cameras travel inside drain and sewer lines to find blockages, root intrusion, and cracks. You get video footage and sewer and storm maps you can hand directly to a plumber.
• Concrete Scanning: Subsurface concrete scanning locates rebar, post-tension cables, and embedded conduits before cutting or coring. This service prevents costly damage to slabs, walls, and decks.
• Leak Detection: Acoustic and tracer methods pinpoint hidden water and gas leaks without tearing up your yard or hardscape.
• Potholing and Pipeline Exposure: Vacuum excavation creates small, non-destructive test holes that confirm pipe depth and material. This pothole location layout protects your crew during underground pipeline construction and pipeline replacement work.

Technology Behind Every Coastline Utility Locating Job

Coastline pairs three locating methods on every job to confirm results. No single tool finds every line, so we cross-verify with multiple technologies. This approach delivers reliable results that hold up on your construction documents and at the dig face.

• Ground Penetrating Radar (GPR): A GPR scan sends radar pulses into the ground to detect both metallic and non-metallic targets. Ground penetrating radar is the primary method for plastic water lines, fiber conduits, and unmarked utilities.
• Electromagnetic Pipe Locating: Electromagnetic detection traces a signal through metallic pipes and tracer wires. Electromagnetic pipe locating returns exact depth and direction for conductive utility lines.
• Vacuum Excavation: Vacuum excavation softens soil with pressurized air or water, then removes it without damaging buried lines. The outcome is precise underground utility detection at the exact dig point.
