-Grading & Drainage

Grading and drainage design in civil engineering is the work of ensuring a level base, or one with a specified slope, for a construction work such as a foundation, the base course for a road, landscape improvements, or surface drainage. Our civil engineers are expert in grading and drainage design and are update with county and city requirements.

-Demolition Plan
  • Safety First. We believe in safety and strive to provide a practical and safe demolition plan in accordance with county and city requirements before any demolition work takes place.

-Erosion Control Plan

We provide a detailed erosion control plan with consideration of minimizing erosion and sedimentation from rainfall at construction and land development sites.

-Land Development

Level 4 experts provide a wide range of development services to meet the needs of both public and private developers. Whether improving the existing structure or building on vacant land, we offer comprehensive design including but not limited to lot line adjustments, lot mergers, subdivision planning, tentative & final map preparations, and slope stability recommendations.

-Sewer & Water Plan / Utility Improvement Plan

  • We provide designs for sewer and water improvement plan which would be a requirement to satisfy the city or county’s infrastructure needs. We also provide public utility improvement plans for the projects which require the proper design to elevate an existing condition and/or encroachments.


-Geotechnical Exploration & Soil Report

Residential and commercial building projects start with a preliminary geotechnical investigation. These investigations include a detailed subsurface investigation and detailed grading and foundation design recommendation. We take pride in providing these services to our clients in a timely manner. We can also provide separate Percolation Report, Infiltration Report, and Compaction Report as required for some projects.

-Retaining Walls and Deep Foundations

Retaining walls are required to deal with many slope stability issues. We provide high-quality and efficient retaining wall design solutions. Our engineers’ experience in retaining walls design prove valuable in designing using state-of-the-art methods.

-Earthquake Engineering

Most Southern California sites are prone to seismic-related hazard and susceptible to liquefaction. Our field investigations include obtaining in-situ dynamic properties of soils. They are used for an extensive liquefaction analysis and mitigation recommendations using state-of-the-art geotechnical practice methods.
