Construction SWPPP Inspections

Construction stormwater compliance needs regular eyes on the site.

Pond Pro provides construction-phase stormwater inspections supporting project SWPPPs, erosion and sediment controls, BMP implementation, and inspection documentation across South Carolina.

Construction-Phase Inspections

Inspection support while the site is active.

A Stormwater Pollution Prevention Plan is not just a plan-set requirement. It has to be implemented, maintained, inspected, and documented throughout construction.

  • SWPPP implementation reviewObserve whether the site is operating in general alignment with the approved on-site SWPPP and inspection requirements.
  • Erosion & sediment controlsReview visible condition and effectiveness of installed BMPs, perimeter controls, stabilized entrances, inlet protection, and related measures.
  • Stormwater conveyances & discharge areasInspect accessible drainage paths, conveyances, discharge points, and downstream conditions included in the project inspection scope.
  • Inspection documentationDocument observed deficiencies, maintenance needs, corrective-action items, photographs, and other information required by the agreed inspection scope.

Professional engineering background

Pond Pro is led by Grayson Vazquez, PE, a South Carolina-licensed Professional Engineer with experience in grading, drainage, pond systems, engineering, and construction.

This allows Pond Pro to approach construction stormwater inspections with both field practicality and an engineering understanding of how the site is intended to function.

South Carolina Construction Stormwater

Know the permit, project size, and inspection frequency.

South Carolina’s current Construction General Permit sets project-specific requirements for SWPPP implementation, inspection frequency, and inspector qualifications. Local MS4 requirements may add additional obligations.

01

Weekly Inspection Requirements

Under the 2026 South Carolina Construction General Permit, active projects disturbing more than 2 acres are generally subject to inspection at least once each calendar week, with no more than 9 days between inspections.

02

Qualified Inspector Requirements

The permit establishes qualification criteria for inspectors on larger projects. The applicable criteria depend on the project, permit, SWPPP preparer, and inspector’s professional registration or approved certification.

03

On-Site SWPPP Records

The on-site SWPPP commonly includes inspection, rainfall, maintenance, corrective-action, and project records used to demonstrate ongoing implementation of the approved stormwater plan.

Scope note: Construction stormwater requirements vary by project size, permit coverage, local MS4 jurisdiction, approved plans, and current permit conditions. Pond Pro confirms the inspection scope before accepting compliance-related work. This page is general information and is not legal advice.

Construction Inspection FAQ

Common SWPPP inspection questions.

What does a construction stormwater inspection look at?

The exact checklist depends on the project documents and permit. Typical observations include disturbed areas, material storage exposed to precipitation, stormwater conveyances, erosion and sediment BMPs, discharge locations, stabilized entrances, evidence of off-site sediment tracking, and maintenance or corrective-action needs.

How often are inspections required?

Frequency depends on the applicable permit and project. For projects disturbing more than 2 acres under South Carolina’s 2026 Construction General Permit, inspections are generally required at least once per calendar week with no more than 9 days between inspections. Smaller projects and local jurisdictions can have different requirements.

Can Pond Pro also inspect the permanent pond or BMP after construction?

Yes. Pond Pro provides both construction-phase SWPPP inspections and post-construction pond/BMP inspections, including recurring annual inspection support where applicable.

Need construction stormwater inspection support?

Send the project location, acreage, permit information, and any current SWPPP or inspection form. Pond Pro can confirm the appropriate inspection scope.
