I’m a professional Civil Engineer specializing in USA civil engineering, site plans, grading and drainage plans, stormwater management, land development, utility layouts, erosion control, and permit-ready civil drawings. I provide detailed residential, commercial, and industrial civil design using AutoCAD and Civil 3D. My services include site development, parking lot design, drainage calculations, SWPPP, septic plans, and PE-stamped drawings where authorized. I deliver accurate, code-conscious solutions tailored to city and county permit requirements.
FAQ
What data do I need to provide to start?
Share your project location/coordinates and topographic data DEM, CAD contours, or survey. If you don't have rainfall or soil data, I can extract regional datasets for you.
Will the report meet local city council/permit standards?
Yes. I build models following USACE, Eurocode, FEMA, or local municipal criteria to ensure your drainage report passes authority review.
Which software versions do you use, and do I get source files?
I use the latest HEC-RAS 1D/2D, HEC-HMS, SWMM, and GIS/Civil 3D. Native source files .prj, .dss, shapefiles are included in Standard and Premium packages.
Can you perform 2D hydraulic modeling for complex sites?
Yes. I build 2D HEC-RAS models for complex terrain, urban areas, and overland flow, providing high-resolution 2D flood inundation maps depth and velocity.
What if the city council requests revisions?
Standard and Premium orders include revision passes to address municipal review feedback, update model parameters, or modify design elements.
