Stormwater Pollution Prevention Plan

Stormwater Pollution Prevention Plan (SWPPP) is a written document with supporting hydrology and hydraulic calculations and engineered drawings that identifies the conditions that must be met for the pre and post development conditions that must be met to ensure that all of the NYS DEC requirements are met.

What Does A SWPPP Include?

A developed SWPPP typically includes information related to a project such as a site description, hydrology analysis, pre and post construction stormwater practices, spill response plans, inspections, and supporting permitting documentation as required by the regulatory agency.

Engineering design plans including but not limited to grading, stormwater, and erosion and sediment control are included as supporting documentation to the SWPPP.

When Is A SWPPP Required?

A SWPPP requirement is based on the authority of the regulatory agency including state, local, and municipality that applies to your site and/or project. Depending on the coverage and permit you are attempting to obtain a SWPPP may be required for the following purposes:

  • Land disturbance over over 1-acre
  • Construction Activities
  • Changes in Site conditions such as runoff discharge points, topography (grading), sediment control practices, and impervious areas
  • Changes or upgrades to existing stormwater practices

Not sure if your site or project qualifies to submit for a SWPPP Inspection? Lakeside Engineering can help navigate and determine the requirements for your proposed land development or site improvement project.

Step 1

Get started with a Project Inquiry today, or fill out our Project Survey→ to tell us about your project

Step 2

Based on your project type, we will provide you with a custom proposal that outlines the scope of services required to bring your project from start to finish

Step 3
Site Visit

We will visit the project site to analyze site conditions, record accurate dimensions, and collect the necessary photography to ensure your project goes smoothly throughout the process

Step 4

We'll then begin the project design, including drafting and performing the structural calculations required to complete your project

Step 5

You'll get the final say on your project with a clear opportunity for changes, revisions, or requests before project completion

Step 6

Once you are satisfied, our Licensed Professional Engineer will stamp and certify your project
