Our Commercial Stormwater Engineering Process

1
Phase 1

Assess Existing Conditions

  • Site inspection and existing infrastructure evaluation
  • Stormwater master plan analysis with existing and proposed conditions modeling
  • Level of service improvement assessment
  • Floodplain mapping and flood zone verification
2
Phase 2

Acquire & Review Record Documents

  • Collect existing plans, survey data, and as-built documentation
  • Review permit history and regulatory compliance records
  • Identify all applicable regulatory requirements across jurisdictions
  • Map the full regulatory framework (WMD, county, city, FDOT)
3
Phase 3

Professional Analysis & Engineering Design

  • Hydrologic and hydraulic modeling for site-specific conditions
  • Retention/detention system sizing and design
  • BMP and water quality treatment engineering
  • Underground drainage, conveyance, and erosion control design
  • Design storm performance verification
4
Phase 4

Permit Applications & Compliance

  • Environmental Resource Permit (ERP) applications
  • NPDES/CGP filing and NOI submission
  • Water Management District coordination
  • FDOT drainage connection approvals
  • Multi-agency review management through approval
5
Phase 5

Construction Oversight & RFB Management

  • Construction phase engineering services
  • SWPPP monitoring and inspection oversight
  • Post-construction certification documentation
  • As-built verification against approved plans

From initial assessment to post-construction certification, we manage the entire stormwater engineering lifecycle.

When You Need Commercial Stormwater Engineering

These situations require professional stormwater engineering from a licensed Professional Engineer.

New Commercial Development or Redevelopment

All new commercial construction requires engineered stormwater management plans and permits.

Land Disturbance of 1+ Acre

SWPPP and Construction Generic Permit (CGP) are mandatory for any project disturbing one or more acres.

Connections to Public Drainage Works

Connecting to municipal drainage infrastructure requires engineering analysis and permit approval.

Modifications to Existing Stormwater Infrastructure

Any changes to existing stormwater systems require engineering review and may trigger new permit requirements.

Site Plan Approval Requirements

Stormwater management plans are a core component of commercial site plan entitlement packages.

Changes to Impervious Surface Area

Adding pavement, buildings, or other impervious surfaces triggers stormwater calculation and permit requirements.

5-Year Stormwater System Recertification

Properties in Palm Beach and Broward counties require PE inspection and recertification every 5 years.

Stormwater System Failure or Non-Compliance Notice

Emergency engineering assessment and remediation design for failing or non-compliant stormwater systems.

Frequently Asked Questions

A comprehensive commercial stormwater management plan includes: stormwater master plan report with existing and proposed conditions modeling, level of service analysis, retention/detention system design, water quality calculations (BMP/LID), erosion and sediment control plans, SWPPP documentation, PE-stamped plan sets, and floodplain mapping documentation.
Florida commercial stormwater projects typically require: Environmental Resource Permits (ERPs) from the relevant Water Management District, NPDES/CGP permits for sites disturbing 1+ acre, FDOT drainage connection permits for projects near state roads, and local building/site plan permits. Multi-agency coordination is often required.
Timelines depend on project scale: small commercial sites (under 1 acre) typically require 2–6 months for design and permitting. Mid-sized projects (1–5 acres) require 6–12 months. Large commercial or industrial projects can require 12–18+ months for complete design, permitting, and construction phase services.
A Stormwater Pollution Prevention Plan (SWPPP) is required under Florida’s Construction Generic Permit for any project disturbing 1 or more acres with stormwater discharge to surface waters or MS4 systems. It includes site descriptions, erosion/sediment controls, inspection schedules, spill prevention, and recordkeeping requirements.
Properties in Palm Beach and Broward counties with on-site drainage infrastructure require professional evaluation every 5 years to ensure systems operate as originally designed and permitted. Inspection covers catch basins, stormwater outfalls, exfiltration trenches, control structures, and retention/detention areas. Non-compliance can result in code violations, fines, and insurance issues.
