Construction Best Management Practices (BMPs)

All construction sites are required to implement the City’s minimum construction BMP requirements, which can be found in the City’s BMP Manual. These requirements apply to small and large construction projects that disturb land. The City’s construction BMP handout (PDF) also summarizes the practices that should be implemented at your site.

If your construction site was inspected for storm water compliance, you will receive an inspection summary report from your inspector which will note any BMP deficiencies observed. These BMP deficiencies should be addressed within three (3) days of the date of the inspection or prior to the next rain event, whichever comes first. Documentation of the corrections made at your project site should be sent to your inspector or to Engineering@nationalcityca.gov

Why is my construction site being inspected?

Construction sites within the City’s jurisdiction are subject to the erosion and sediment control practices pursuant to National City Municipal Code Chapter 15.70. City inspectors routinely assess construction sites to ensure that sediment and waste from construction activities are properly managed to prevent pollutants from entering our storm water conveyance system.

My construction site was inspected.  What do I do now?

If there were violations found on your construction site, ensure that the violations are corrected and appropriate proof of the corrections are provided to the inspector or Engineering Department in a timely manner. 

What is a SWPPP?

SWPPP stands for Storm Water Pollution Prevention Plan. It is a document that will describe how a construction site will minimize or prevent pollution. They are required for sites that disturb one acre or more of land and are subject to the State’s Construction General Permit. The City also has the authority to require smaller construction sites within its jurisdiction to develop a SWPPP, where necessary.
