Essential Planning Steps
1. Create a Site Plan
A detailed site plan is required by both utility companies and permitting offices. Your site plan should include:
- Property boundaries
- Existing structures
- Proposed electrical service location
- Utility easements
- Access routes
2. Determine Service Requirements
Work with a licensed electrician to determine your electrical needs:
- Service size (100, 200, or 400 amps)
- Overhead vs. underground service
- Meter location
- Main panel requirements
- Future expansion needs
3. Obtain Necessary Permits
Washington State requires specific permits for electrical work:
- Electrical permit from L&I
- Excavation permit (if needed)
- Right-of-way permit (if crossing public property)
- Environmental permits (if applicable)
- Local building permits
“According to the National Fire Protection Association, about 38,000 reported home fires are reported each year resulting in about 1,200 injuries and $668 million in direct property damage due to electrical issues.”
Working with experienced professionals during the planning phase can help you avoid costly mistakes and delays. A qualified excavation contractor can assess your site’s specific challenges and recommend the most efficient approach for preparing your property.

Proper site preparation is critical for a successful electrical service installation. This phase involves several key steps that must be completed correctly to ensure safety, compliance, and long-term reliability of your electrical service.
Essential Site Preparation Steps
1. Property Clearing
Before excavation can begin, the site must be properly cleared:
- Remove vegetation along service route
- Clear obstacles and debris
- Identify and mark existing utilities
- Establish access routes for equipment
2. Underground Utility Locating
Washington law requires locating existing utilities:
- Call 811 at least two business days before digging

- Document all markings
- Verify private utility locations
3. Trench Excavation
Proper trenching is critical for underground service:
- Minimum 24″ depth per WA code
- Proper width for conduit installation
- Sloped sides for safety
- Appropriate bedding material
4. Conduit Installation
Conduit protects underground electrical lines:
- Correct conduit type and size
- Proper joints and connections
- Pull strings for wire installation
- Inspection before backfilling
Equipment and Expertise Required
Site preparation for electrical service requires specialized equipment and expertise. Professional excavation contractors have the necessary tools and knowledge to complete the work efficiently and safely:
Specialized Equipment
- Mini-excavators for precise trenching
- Trenchers for long, straight runs
- Compaction equipment for proper backfilling
- Laser levels for maintaining proper depth
- Underground utility locators
Professional Expertise
- Knowledge of soil conditions and stability
- Understanding of electrical code requirements

Learn About Our Electrical Excavation ServicesCommon Challenges and Solutions
Preparing property for electrical service in Washington State can present various challenges. Understanding these potential obstacles and their solutions helps ensure a smoother project experience.
Rocky Soil Conditions
Challenge: Washington’s varied terrain often includes rocky soil that complicates excavation.
Solution: Specialized equipment like rock hammers and larger excavators can effectively manage rocky conditions. In extreme cases, alternative routing may be considered.
Wetlands and Environmental Areas
Challenge: Many Washington properties contain wetlands or environmentally sensitive areas with strict regulations.
Solution: Professional environmental assessment and specialized permitting can address these concerns. Horizontal directional drilling may be used to minimize impact.
Utility Conflicts
Challenge: Existing underground utilities may conflict with planned electrical service routes.
Solution: Comprehensive utility locating services and ground-penetrating radar can identify conflicts early. Route adjustments can be made during the planning phase.
Steep Terrain
Challenge: Washington’s hilly landscapes can make standard trenching difficult and potentially hazardous.
Solution: Terraced excavation approaches and erosion control measures can safely accommodate slopes. Specialized equipment operators with hillside experience are essential.
Permit Delays
Challenge: Complex permitting processes can cause significant project delays.
Solution: Early application submission and working with contractors familiar with local permitting processes can minimize delays. Pre-application meetings with officials often help identify requirements early.
Weather Constraints
Challenge: Washington’s rainy seasons can impact excavation work and create muddy conditions.
Solution: Careful project timing and temporary weather protection measures can mitigate weather impacts. Proper drainage and soil stabilization techniques help manage wet conditions.
Working with experienced professionals who understand Washington’s unique challenges is the best way to overcome these obstacles. At Indepth Excavation, we’ve successfully managed these challenges on countless properties throughout Snohomish County and beyond.

Get Expert Help for Challenging SitesFrequently Asked Questions
How long does the entire process of preparing property for electrical service typically take in Washington State?
The complete process typically takes 6-12 weeks from initial application to final connection. This timeline includes permit acquisition (2-4 weeks), site preparation (1-2 weeks), electrical installation (1-2 weeks), inspections (1-2 weeks), and utility connection (1-2 weeks). Weather conditions, property challenges, and permit complexities can extend this timeline.
What permits are required for new electrical service in Snohomish County?
In Snohomish County, you’ll typically need an electrical permit from Washington State Labor & Industries, a utility connection permit from your local utility provider, and potentially an excavation permit if working in public right-of-way areas. Properties with environmental designations may require additional permits. Indepth Excavation can help identify all necessary permits for your specific property.
Can I do the excavation work myself to save money?
While homeowners can legally perform excavation on their own property, we strongly recommend professional excavation services for electrical installations. Improper trenching depth, inadequate conduit installation, or damage to existing utilities can lead to failed inspections, service delays, and potentially dangerous conditions. Professional excavation ensures code compliance and proper documentation for inspections.
How deep must electrical service trenches be in Washington State?
Washington State follows the National Electrical Code (NEC) requirements for trench depth. For direct burial cables, the minimum depth is 24 inches. When using conduit, the minimum depth is typically 18 inches for residential applications. However, local utility providers may have additional requirements, sometimes specifying depths of 30-36 inches. Our team ensures all trenching meets or exceeds both state code and utility provider specifications.
How do I coordinate between excavation contractors and electricians?
Coordination between excavation contractors and electricians is crucial for a successful installation. At Indepth Excavation, we work closely with licensed electrical contractors like Melby Electric to ensure seamless project management. We can either work with your chosen electrician or recommend qualified partners who understand Washington State requirements.
