I will prepare structural engineering and county permit drawings for california and tx


About this gig
Need professional engineering drawings and permit documentation for a project in California or Texas?
I provide structural engineering drawings, county permit plans, grading and drainage plans, and stormwater documentation tailored to your project requirements.
Whether you are a homeowner, contractor, builder, architect, or property developer, I focus on clear, coordinated plans that support construction planning and the permit review process.
My work considers site conditions, elevations, drainage flow, grading requirements, structural details, and applicable local criteria. Services can also include Stormwater Pollution Prevention Plan (SWPPP) documentation, where required by the project and permit conditions.
To get started, share your project location, existing plans or survey, proposed site layout, and any available county comments or permit checklist. I will review the available information and confirm the appropriate scope before work begins.
Message me before ordering for large or complex projects. Lets establish the right documentation package for your project.

FAQ
Can you prepare grading and drainage plans using my existing survey?
Existing boundary and topographic surveys can support grading and drainage design. I review elevations, site conditions, proposed improvements, and drainage patterns. Missing information or additional engineering calculations will be identified as needed.
Can you include SWPPP and stormwater documentation for California or Texas permits?
SWPPP and stormwater documentation are available based on project scope and permit requirements. Requirements depend on construction activities, disturbed acreage, discharge conditions, and applicable state and local regulations.
Can you coordinate structural drawings with grading and drainage plans?
Yes. When both services are included, I coordinate relevant building locations, elevations, site grading, drainage flow, and supporting details to reduce conflicts between the drawing sets. Any missing or inconsistent information is identified for clarification rather than assumed to be verified.
