Industrial Civil Site Compliance & Permitting Support 

Client: Confidential Industrial Site Owner
Project Area: Multi-building Industrial facility
Status: Completed
Role: Prime Civil Engineer & Permitting Consultant

Project Overview

Lentz Engineering is currently assisting a confidential energy services client with civil engineering and permitting services to bring their multi-structure commercial site into full compliance with local development regulations. The property was cited for unpermitted structures, requiring immediate action to assess existing improvements, develop as-built documentation, and secure civil permits through Harris County.

Our team conducted onsite investigations, identified permit violations, and is preparing comprehensive civil construction drawings to support detention infrastructure, grading, and utility planning. This project required close coordination with county officials to meet deadlines, address code violations, and support the client in navigating a complex permitting path for legacy development.

Key Services Provided

  • Onsite investigation and assessment of existing site conditions and unpermitted structures

  • Coordination with local regulatory agencies to determine permitting and platting requirements

  • Preparation of full civil construction drawings including site plan, grading, drainage, detention, and SWPPP

  • Development of drainage and detention calculations for multiple existing and proposed systems

  • Review and analysis of legacy plans, with updates to reflect actual site improvements

  • Berm and channel redesign to accommodate revised stormwater flow and compliance needs

  • Platting services and boundary adjustments to align site with current development standards

  • Permit processing and response to review comments with Harris County authorities

    Project Highlights

    • Supported resolution of multiple code violations on an active industrial site without disrupting operations

    • Delivered a comprehensive permitting strategy for previously unrecorded structures

    • Engaged directly with county engineering and inspections staff to clarify compliance expectations

    • Developed scalable drainage and detention solutions across multiple infrastructure zones

    • Enabled the client to maintain business continuity while bringing the site into full regulatory compliance
