Frequently Asked Questions
Find answers to common questions about SWPPP compliance, erosion control services, and our process.
What is a SWPPP and when is it required in Texas?
A Stormwater Pollution Prevention Plan (SWPPP) is required by the Texas Commission on Environmental Quality (TCEQ) for any construction project that disturbs one or more acres of land, or is part of a larger common plan of development exceeding one acre. Under TCEQ Permit TXR150000, the SWPPP must outline all erosion and sediment control Best Management Practices (BMPs) that will be implemented during construction. Non-compliance can result in fines of up to $25,000 per day per violation.
How long does it take to prepare a SWPPP?
A standard SWPPP can typically be prepared within 5-10 business days, depending on the complexity of the project and site conditions. Expedited services are available for time-sensitive projects. The SWPPP must be completed and the Notice of Intent (NOI) filed with TCEQ at least 7 days before construction activity begins
What is the difference between hydroseeding and hydromulching?
Hydroseeding applies a slurry of seed, water, fertilizer, and mulch to establish vegetation quickly on disturbed areas. Hydromulching uses a thicker mulch application focused on immediate erosion protection, often without seed, to stabilize soil on slopes and disturbed areas. Both are effective erosion control BMPs commonly used on Houston-area construction sites to achieve the 70% vegetative cover required for SWPPP termination.
How often are SWPPP inspections required in Texas?
TCEQ requires SWPPP inspections at least once every 14 calendar days, and within 24 hours after a rainfall event of 0.5 inches or more. Houston’s average of 49+ inches of annual rainfall means storm-triggered inspections are frequent. Each inspection must be documented with detailed reports covering BMP condition, maintenance needs, and corrective actions taken.
What areas do you serve in the Houston metro?
We serve the entire Greater Houston metropolitan area, including Katy, Sugar Land, The Woodlands, Pearland, Cypress, League City, Conroe, Baytown, Pasadena, and over 100 surrounding communities across Harris, Fort Bend, Montgomery, Brazoria, Galveston, and Liberty Counties in Southeast Texas.
Do you handle both residential and commercial projects?
Yes. We provide erosion control and SWPPP services for residential subdivisions, commercial construction, municipal infrastructure, industrial sites, road and highway projects, and renewable energy installations. Whether your project disturbs 1 acre or 500 acres, our team has the experience and equipment to handle it.
What is a Notice of Intent (NOI) and how do I file one?
A Notice of Intent (NOI) is a formal notification filed with TCEQ through the STEERS online system indicating that a construction project will be covered under the TPDES Construction General Permit (TXR150000). It must be filed at least 7 days before construction begins. Houston Erosion Control handles the entire NOI filing process for our clients, including STEERS account setup and permit coordination.
Can you take over SWPPP management for an existing project?
Absolutely. We regularly assume SWPPP management at any stage of construction. This includes conducting an initial site assessment, updating existing documentation, installing or repairing BMPs, and providing ongoing inspections and maintenance. We can also help resolve existing compliance issues or prepare for upcoming TCEQ inspections.
How much does erosion control cost in Houston?
Erosion control costs vary based on project size, site conditions, and the specific BMPs required. Silt fencing typically ranges from $3-$8 per linear foot installed. Hydroseeding costs $0.08-$0.20 per square foot. Construction entrances range from $1,500-$6,000. SWPPP documentation packages and inspection services are quoted per project.

What makes Houston Erosion Control different from other providers?
Most competitors in the Houston market either write SWPPP documents OR install BMPs — we do both. As a turnkey SWPPP and erosion control contractor, we provide one point of contact for compliance documentation, field installation, ongoing inspections, and maintenance. This integrated approach means faster timelines, less coordination friction, and lower risk for builders and developers.
