About
Licensed Professional Engineer and Civil 3D specialist with 14+ years of land development experience delivering grading, drainage, and utility design for residential, commercial, and mixed-use projects.
I help engineering firms, architects, and contractors complete technical tasks quickly and accurately. My focus is fast-turn production and calculations support rather than full project management. If you need clean drawings, solid drainage numbers, or redlines knocked out without handholding, I can jump in and get it done.
Typical work includes:
• Civil 3D grading plans, surfaces, and earthwork volumes
• Storm sewer layouts, pipe networks, and profiles
• Rational method and detention sizing calculations
• Hydraflow/SWMM modeling
• Drainage report exhibits and technical documentation
• Plan set production and redline incorporation
• Quantity takeoffs and constructability checks
I run my own civil engineering practice (Katz LDE), so I’m used to working independently, meeting deadlines, and delivering reviewer-ready work with minimal direction. You get senior-level engineering execution without the overhead or training time.
Available for short-term, task-based, or overflow support. Quick turnaround and clear communication.
