Commercial Storm Water Management
Commercial properties face complex storm water management challenges that require professional engineering to solve. Our team delivers comprehensive stormwater solutions — from initial assessment through permitting and construction oversight — to keep your property compliant and protected.
Engineering solutions for commercial properties facing complex storm water management challenges across Florida. Our team of Licensed Professional Engineers delivers solutions tailored to Florida's unique drainage challenges.
Commercial stormwater management in Florida is governed by a web of federal, state, and local regulations that can be difficult to navigate without specialized expertise. The South Florida Water Management District (SFWMD) requires Environmental Resource Permits for most commercial projects that affect surface water, while county and municipal building departments enforce their own drainage codes. Non-compliance can result in fines, stop-work orders, and liability for downstream flooding.
Our engineering team brings deep experience across the full spectrum of commercial stormwater challenges. We design systems for new development, retrofit aging infrastructure on existing properties, and help property owners return to compliance after violations. Every project begins with a thorough assessment of existing conditions — including review of original permit documents, field inspection of drainage infrastructure, and analysis of system performance during storm events.
From shopping centers and office parks to industrial facilities and HOA communities, we design stormwater systems that manage peak flows, treat water quality before discharge, and meet all regulatory requirements. Our designs account for Florida's high-intensity rainfall, flat topography, high water tables, and the specific regulations of your project's jurisdiction. We also develop long-term capital improvement programs that help property owners budget for necessary upgrades and stay ahead of system failures.
Comprehensive Site Design
Full stormwater management system design including pipe networks, retention and detention systems, outfall structures, and water quality treatment — engineered for Florida's regulatory requirements
Water Quality Pre-Treatment
Nutrient removal systems, sediment control BMPs, baffle boxes, and exfiltration trenches designed to meet SFWMD and FDEP water quality standards before discharge
Flood Control Engineering
Detention and retention pond design, overflow structures, and conveyance systems sized to manage peak flows from Florida's 25-year and 100-year storm events
Permit Compliance
Complete permit analysis and application management for SFWMD Environmental Resource Permits, county building permits, FDEP permits, and NPDES compliance
Infrastructure Assessment
Comprehensive evaluation of existing stormwater systems including pipe condition assessment, pond capacity analysis, and outfall performance review
Capital Improvement Planning
Strategic 5-year plans that prioritize stormwater upgrades, establish budgets, and schedule improvements to prevent system failures and maintain compliance
- Achieve and maintain full regulatory compliance with SFWMD, county, and municipal requirements
- Protect commercial assets from flood damage and associated business interruption
- Reduce long-term maintenance and repair expenses through proper engineering
- Develop a prioritized 5-year capital improvement program for budgeting
- Reduce the impact and cost of sudden infrastructure failures
- Minimize liability exposure from downstream flooding or water quality violations
Our engineers inspect your property's stormwater infrastructure, evaluate drainage performance, identify problem areas, and document existing system components. We photograph conditions and collect data needed for engineering analysis.
We obtain original permit documents, as-built drawings, and maintenance records from agencies and property files. This historical data reveals design intent, permitted capacities, and any modifications that may have occurred since construction.
Using field data and record documents, our Licensed Professional Engineers perform hydrologic and hydraulic analysis, design system improvements or new infrastructure, and prepare construction-ready drawings with detailed specifications.
We prepare and submit all required permit applications — including SFWMD ERPs, county building permits, and FDEP authorizations. Our team manages reviewer correspondence and resolves comments to keep approvals on track.
During construction, we provide engineering oversight to verify the stormwater system is built according to our design. This includes shop drawing review, field inspections, and as-built certification upon completion.
Before You Start: Survey Data Required
Our engineers need elevation data to design your stormwater management system. A current topographic survey provides the contours, grades, and existing drainage structures we use to calculate flow paths and pipe sizes.
Understanding regulatory requirements is critical for any drainage project in Florida.
- SFWMD Environmental Resource Permits (ERP) are required for commercial projects that affect wetlands, floodplains, or surface water management systems within the district
- NPDES stormwater permits are required for construction sites disturbing one acre or more, and for certain industrial and commercial operations discharging to waters of the state
- County building departments require engineer-stamped stormwater management plans for new development, redevelopment, and site modifications exceeding impervious area thresholds
- Water quality pre-treatment is required before discharge from commercial properties, with specific nutrient loading and Total Maximum Daily Load (TMDL) requirements varying by basin
- FDEP permits may be required for projects near wetlands, Outstanding Florida Waters, or within Areas of Critical State Concern
- Retention and detention systems must be designed per the applicable water management district criteria, typically managing the first inch of rainfall for water quality and the 25-year/72-hour storm for flood control
Florida Property Challenges
Parking Lot Flooding
Undersized or clogged storm drain systems lead to standing water that damages pavement, creates liability risks, and drives away customers. We design systems that handle even Florida's heaviest rainfall events.
Retention Pond Failures
Aging retention ponds lose capacity due to sediment buildup, bank erosion, and vegetation overgrowth. When ponds fail, properties flood and permit violations follow. We engineer restoration plans.
NPDES Compliance Violations
Commercial properties must prevent polluted stormwater from entering waterways. Failed inspections lead to fines and legal action. Our water quality BMP designs achieve and maintain compliance.
Development Permit Delays
Complex commercial projects require Environmental Resource Permits from SFWMD or other water management districts. Incomplete or incorrect submittals cause costly delays. Our 100% approval rate prevents this.
HOA Community Drainage Failures
Aging community drainage infrastructure — shared retention ponds, outfall pipes, swales between homes — requires professional engineering assessment and capital improvement planning.
