Understand Your Stormwater BMP — Before Problems Start
Stormwater Best Management Practices (BMPs) are engineered systems that protect your property, your community, and your local environment from flooding, erosion, and water-quality issues. This guide explains what they are, how they work, and why they must be maintained.
COMMON TYPES OF STORMWATER BMPs
1. Retention & Detention Ponds
Engineered basins designed to capture, store, and slowly release stormwater.
Common problems: erosion, sediment buildup, bank failure, clogged inlets/outlets.
2. Bioswales & Swales
Shallow, vegetated channels that move stormwater while filtering pollutants.
Common problems: improper grading, sedimentation, vegetation loss.
3. Permeable Pavement BMPs
Allows water to pass through instead of running off.
Common problems: clogging from sediment and organics.
4. Rain Gardens / Bioretention Areas
Capture and infiltrate runoff using soil, plants, and engineered media.
Common problems: ponding, plant death, clogging, soil compaction.
5. Drainage Systems & Catch Basins
Move water off surfaces and into controlled conveyance pathways.
Common problems: pipe collapse, clogging, root intrusion, basin overflow.
6. Outfalls & Energy Dissipation Systems
Where stormwater exits the system into a pond, creek, or channel.
Common problems: scour, blowouts, undermining, bank collapse.
7. Infiltration Trenches & Filters
Allow runoff to soak into the ground.
Common problems: clogging, failure to infiltrate, sediment migration.
Your turnkey stormwater partner
Enforcement is tightening. Most properties find out with a Notice of Violation.
Federal pressure is pushing state and local governments to crack down, and most property managers don’t know it’s coming until a Notice of Violation lands on their desk. The ones who do know rarely know where to start.
We help you navigate stormwater, mitigate risk, and create a predictable remediation plan that works for your budget.
What Is a Stormwater BMP?
A Stormwater BMP (Best Management Practice) is an engineered system designed to manage, control, and filter stormwater runoff.
Its purpose is to:
- Prevent flooding
- Reduce erosion
- Protect water quality
- Capture or slow stormwater
- Filter pollutants before they reach downstream systems
- Prevent structural damage to surrounding land
BMPs are required under NPDES and MS4 stormwater regulations for properties across the United States.
Key Insight:
BMPs are not natural features. They are man-made systems that require ongoing inspections, cleaning, and maintenance to function properly.
WHY BMPs MATTER
Stormwater BMPs Are Critical Infrastructure — Just Like Roads, Pipes, and Utilities
When BMPs fail or clog, the entire property is impacted.
Consequences of neglected BMPs:
- Flooding of yards, paths, greens, roads, and buildings
- Erosion along slopes, embankments, and pond edges
- Sediment buildup leading to pond shallowing
- Poor water quality, algae blooms, and contamination
- Sinkholes, washouts, and infrastructure undermining
- Regulatory violations, fines, and NOVs
- Higher long-term repair costs
A healthy BMP protects:
- Property value
- Aesthetics
- Resident/member experience
- Environmental health
- Compliance status
- Your bottom line
Why BMP Maintenance Is Required
Stormwater BMPs must be inspected and maintained — it’s the law.
Under MS4 and NPDES regulations, properties are responsible for keeping their BMPs functioning.
Failure to maintain them leads to:
- NOVs (Notices of Violation)
- Fines
- Required emergency repairs
- Increased liability
- Environmental penalties
Common required maintenance activities:
- Sediment and debris removal
- Clearing inlets/outlets
- Shoreline stabilization and erosion control
- Drainage pipe cleaning
- Vegetation restoration
- Outfall and structure cleaning
- Grading correction
- Bank and slope repair
Important:
Most BMP failures happen because nobody is performing routine maintenance.
Signs your BMP Is Failing
Use this as a diagnostic checklist:
- Standing water where it shouldn’t be
- Erosion, washouts, or slumping banks
- Sediment buildup, murky water, or browning pond edges
- Iron staining or algae blooms
- Clogged drainage structures
- Water flowing around, not through, the system
- Overflowing catch basins or inlets
- Outfalls washing out or scouring holes
- Sinkholes or depressions near stormwater features
If any of these are happening, the BMP is underperforming or failing.
Our BMP Support Services
We offer full-service support for stormwater BMPs, including:
- Stormwater BMP inspections (CEPSCI standards)
- Annual and quarterly maintenance plans
- Sediment removal and erosion repair
- Drainage system cleaning and restoration
- Outfall stabilization
- Bank and slope reinforcement
- Vegetation and ecosystem rebuilding
- Reporting and compliance documentation
We evaluate your BMP like a regulator—but help you fix issues before fines or failures.
Who This Page Is for
This BMP guide is designed for:
- HOA property managers
- Golf course superintendents
- Municipal stormwater staff
- Commercial facilities
- Developers and EPC firms
- Lakefront, pond, and riverfront property owners
Understanding your BMP is the first step to protecting your property.
What we do
Stormwater services, start to finish
Not sure where to start? We assess your property, prioritize what matters most, and build a plan around your budget, so every dollar goes toward the right solution.
Compliance, Inspection & Maintenance
Know where you stand before a regulator tells you. Inspections, documented O&M programs and ongoing maintenance keep your property compliant year round.
Sediment, Erosion & Environmental Stabilization
Stop erosion before it spreads. We repair pond banks, refurbish riprap and stabilize shorelines with proven and bioengineered methods.
Stormwater & Sewer Infrastructure
We repair and replace water mains, sewer lines, storm pipes, manholes and pumps, safely and with minimal disruption to your property.
Stormwater Drainage Systems
Storm drain replacement, pipe installation, catch basin repair, hydro vac cleaning and outfall clearing.
Ditching & Grading
Poor grading is often the root cause of drainage problems. We reshape swales, regrade slopes and rebuild drainage pathways.
Outfalls & Emergency Stabilization
When erosion turns urgent, we respond fast to washouts, scour damage and channel breaches, stabilizing the site before it gets worse.
What clients say
Superintendents and managers who have worked with us
“Their guidance and project coordination ultimately saved us nearly $400,000 while delivering an excellent outcome. I would highly recommend them to anyone looking for an honest, knowledgeable team that puts the client relationship first.”
Kyle Callahan
Director of Golf Course and Grounds, Thornblade Club
“Right from the start, they were transparent, flexible, and always kept us well-informed. Moreover, as a contractor operating in a golf environment, their understanding for golf etiquette was truly commendable, demonstrating a deep respect for our space and its users.”
Joey Franco
Superintendent, Daniel Island Club, Charleston SC
“I’ve got to hand it to them, they knew exactly what they were doing. They sat down with us, really listened to our concerns, and came up with a plan that worked for our unique situation.”
