Civil Engineering Services in Pasadena & Los Angeles
Before construction begins, your site needs to be engineered. ATP provides civil engineering documentation — grading plans, drainage design, erosion control, and site utility coordination — prepared to city submission standards as part of the design process.
Civil Engineering Services ATP Provides
ATP develops civil engineering documentation for residential and commercial projects throughout Los Angeles. Every set of civil plans is tailored to your specific site conditions, zoning requirements, and city submission standards.
Grading Plans
Detailed grading documentation showing how the land will be shaped, cut, and filled to prepare the site for construction — required for most new builds, additions, and hillside projects before a grading permit is issued.
Drainage Design
Engineering documentation showing how surface water and runoff will be managed on your site — designed to protect the structure, neighboring properties, and meet city drainage requirements.
Erosion Control Plans
Site erosion control measures designed to prevent soil displacement during and after construction — required by most Los Angeles area cities as part of the grading permit process.
Retaining Wall Design
Civil engineering documentation for retaining walls required to manage grade changes on sloped or hillside lots — coordinated with structural engineering and grading plans.
Site Utility Coordination
Documentation showing how water, sewer, and drainage systems connect from the street to your site — required before construction begins and coordinated with city utility departments.
Land Consultant Coordination
ATP coordinates with surveyors, geotechnical engineers, and land consultants to ensure all site data is accurate and reflected in civil engineering documentation before plans are finalized.
Everything Involved in Your Civil Engineering Documentation
Civil engineering involves coordination across multiple disciplines — architecture, structural, geotechnical, and city review. ATP manages every component to ensure your civil plans are complete, code-compliant, and ready for city submission.
Site Analysis & Existing Conditions Review
Before civil plans are developed, ATP reviews your property's existing conditions — topography, drainage patterns, soil type, and any site constraints that will affect civil engineering design.
Grading & Drainage Coordination
ATP develops grading and drainage plans in coordination with architectural and structural documentation — ensuring all site work is aligned with the proposed construction before city submission.
Geotechnical Coordination
ATP coordinates with geotechnical engineers on soils reports and site investigation findings — ensuring civil engineering design reflects actual site conditions before plans are finalized.
Retaining Wall & Structural Coordination
Where retaining walls are required, ATP coordinates civil engineering documentation with structural engineering plans — ensuring both sets are fully aligned before city submission.
City Plan Check Support
When the city issues civil engineering corrections, ATP reviews each item, coordinates required revisions, and manages resubmittal to keep your approval on schedule.
Grading Permit Coordination
ATP manages grading permit submission and coordination with city departments — separate from but aligned with the building permit process where both are required simultaneously.
How Civil Engineering Works With ATP
Civil engineering documentation is developed as part of ATP's coordinated design process — integrated with architectural and structural plans from the start. Here's how ATP manages civil engineering from consultation through permit approval.
Consultation
ATP reviews your project scope, property conditions, and civil engineering requirements. This is where we determine what civil documentation is required, identify any site constraints, and outline the design path forward. No commitment required at this stage.
Site Analysis & Existing Conditions Review
ATP reviews your property's topography, drainage patterns, soil conditions, and any existing site constraints that will shape civil engineering design before work begins.
Geotechnical Coordination
Where required, ATP coordinates soils investigation and geotechnical reporting to ensure civil and foundation design is based on actual site conditions.
Civil Plan Development
ATP develops complete civil engineering documentation — grading plans, drainage design, erosion control, retaining wall design, and site utility coordination — aligned with architectural and structural plans.
Plan Check Submission & Support
ATP submits civil plans to the appropriate city departments and manages the plan check process — tracking status, responding to corrections, and coordinating revisions through full permit approval.

Frequently Asked Questions About Civil Engineering
Do I need civil engineering for my project?
Most new construction, hillside projects, ADUs, and large additions require civil engineering documentation — particularly grading and drainage plans — before a grading permit is issued. The specific civil engineering requirements for your project depend on scope, site conditions, and jurisdiction. ATP reviews this during your initial consultation.
Is civil engineering included with architectural and structural plans?
Civil engineering is coordinated as part of ATP's design process where required by your project scope and site conditions. Whether it is included as part of a broader design engagement or handled as a standalone service depends on your specific project — ATP will outline exactly what is required during consultation.
What is a grading permit and do I need one?
A grading permit authorizes earth movement on your site — cutting, filling, and shaping the land before construction begins. Most new builds, hillside projects, and projects with significant grade changes require a grading permit before construction can begin. ATP manages grading permit submission and coordination as part of the civil engineering process.
Does ATP handle civil engineering for hillside projects?
Yes. Civil engineering is particularly critical on hillside and sloped lots — grading, drainage, erosion control, and retaining wall design all require careful coordination on hillside sites. ATP has direct experience managing civil engineering on complex hillside projects throughout Los Angeles.
What is the difference between civil engineering and structural engineering?
Structural engineering focuses on the building itself — foundation design, framing systems, and load calculations. Civil engineering focuses on the land the building sits on — grading, drainage, erosion control, and site utility coordination. Both disciplines are required on most new construction projects and are developed in coordination with each other.
Does ATP coordinate with geotechnical engineers?
Yes. ATP coordinates with geotechnical engineers on soils reports and site investigation findings — ensuring civil and foundation design reflects actual site conditions before plans are finalized and submitted.
Can ATP step in if my civil engineering plans are incomplete or deficient?
Yes. For clients with existing civil plans that are incomplete or need correction, ATP can review current documentation, identify issues, and coordinate revisions before city submission.
