Stormwater Authority Division

Bridging Regulatory Compliance with Environmental Stewardship


Stormwater Engineering Management Services

Z6 Commissioning’s Stormwater Engineering – Identifying the risk, Managing the response.

Any doubts as to the vital importance of Stormwater Management would quickly evaporate after engaging in a conversation with anyone who experienced the effects of Hurricane Harvey first hand. Z6 Commissioning’s Stormwater Authority Division was established to mitigate the detrimental effects of flood and destructive water levels and surges. From small site-specific projects to county or region-wide assessments, Z6 Commissioning is the authority for all aspects of stormwater management.

Stormwater Engineering

1. Flood Mitigation Operations (planning, design, construction oversight)

2. Wet and Dry Flood Proofing (FEMA)


Our stormwater engineering services encompass the spectrum of initial project conception to post-event analysis. Initial project conception addresses the flood risk mitigation needs during the planning phase of the project. We work closely with clients to establish their tolerable risks to flood damage. Next, we provide a project scope that clearly defines the flood mitigation features (both structural and non-structural), the anticipated project budget, and potential impacts to current operations during construction, operation and maintenance. This phase incorporates close coordination with the client, including users and operations personnel, to secure the best overall flood risk mitigation system for the best value.

Following any stormwater event, our extensive forensic investigation includes onsite damage assessment, “as-built” drawing reviews, and hydraulic modeling, structural engineering and geotechnical engineering reviews as needed, along with client interviews to understand operations and listen to users that have event-specific information. This post-event analysis is a vital step in the flood mitigation operation; the information gathered forms the foundation for developing the flood mitigation features. Once the post-event analysis is complete, we encourage all of our clients to continue into the project conception phase to establish the tolerable risks of any proposed flood mitigation plan.

Project Management

Start to finish project coordination.

Our project management services range from small single-use sites with one owner and one design team to large regional sites with multiple stakeholders and design teams. As project manager, our first and foremost responsibility is to ensure the best outcome with the best value for our client. Our project management services primarily focus on general civil construction from project planning to project closeout. Past projects have undertaken issues of flood control, channels, levees, floodwalls, dams, flood mitigation operations, wet flood proofing, dry flood proofing, navigation channels, dredge material disposal, geotechnical engineering, and structural engineering issues.

Geotechnical Engineering

1. Foundation investigation oversight

2. Earthen structure design (dams, levees, flood control channels, shallow and deep draft navigation channels, harbors and other navigation features)

3. General civil construction activities (shallow foundations and general site work oversight)

Our geotechnical engineering services focus on plan formulation, field investigation oversight, and construction oversight. We provide owner agent services to clients to ensure the project scope, design, and construction are beneficial investments. We work closely with clients to verify the proposed construction is commensurate with their needs, budget, and timeframe. We aid clients in evaluating, selecting and overseeing design firm proposals and provide design reviews to ensure they receives the best value design for their needs. Our construction oversight services include daily inspections for contract compliance, third-party materials testing, progress reviews, and dispute resolution.

Structural Engineering

1. Windstorm Engineering

2. Concrete Design

3. Steel Design

Unveiling Hidden Leaks

Harness the power of Electronic Roof Leak Detection to unveil hidden leaks, ensuring your roof’s integrity and longevity.

Technology for Roof Security

Our advanced ELD services provide precise leak detection, utilizing technology to secure your roof against water damage and subsequent costly repairs.

How It Works

There are two methods of ELD:

Low Voltage Vector Mapping

Low Voltage Vector Mapping requires a wet surface which makes it the method-of-choice for green roofs and/or rainy days. Wet surfaces create a conductive medium over the entire surface of the roof. A trace wire is applied to the perimeter of the roof area to be tested. This trace wire is then connected to a pulse generator. From the pulse generator, a ground wire is connected to a penetration in the structural roof deck to complete the circuit covering the testing area. The penetrations and drains in the roof system are then isolated and connected to the perimeter trace wire. The roof membrane acts as a barrier between the electrical circuit. If there are any breaches in the roofing membrane, current will flow through this breech and connect the circuit, detected by a trained Z6 technician utilizing a receiver and a set of probes. The technician traces the sensor’s direction until all breaches are identified.

High Voltage Testing

High Voltage ELD testing is performed on dry, horizontal and/or vertical surfaces. The Z6 technician connects a ground wire to a penetration in the structural deck. A portable generator with an electrode brush made of highly conductive bristles is utilized to emit an extremely high voltage (low amperage for safety) current to the roof deck. The technician then sweeps over the roof
membrane acting as a barrier with this conductive brush to cover all horizontal and vertical roof surfaces. When a breach is passed over, the electrical circuit is completed and a signal is emitted that identifies the exact location of the membrane breech, regardless of the size.

Why Electronic Leak Detection?

Cost Savings: Testing is completed within hours instead of days required for the traditional flood testing approach.

Non-Invasive: Leaks are discovered without saturating the penetrated area.

Targeted Accuracy: Identify pinhole leaks and breaches for the most efficient diagnosis, saving time and decreasing labor costs.

Quality Control: Ensure quality assurance integrity to certify the watertight, safe, and sustainable performance of new roof membranes.

Eco-Friendly: Reduced water consumption and lower energy bills by not flooding the roof.

Meet LEED Initiatives: Verify green roof membranes prior to installing overburden.

Warranty Compliance: Requirements can be validated through verification, enabling faster hand over.

Reduced Risk: Reduces the possibilities of trapping water under the membrane leading to both wet insulation and mold growth.


1. Insulated and non-insulated low-slope roof systems (excluding metal-coated and carbon black EPDM membranes)
2. Ballasted roof systems (low voltage)
3. Ponded and flooded roofs (low voltage)
4. Green roofs (hot applied and cold applied membranes)
5. Plaza decks and balconies
6. Horizontal and vertical roof and waterproofing membranes
7. Patios, planters and waterproofing between split slabs
8. Pools and fountains
