WHAT TYPES OF CONTROLS ARE THE PROJECTS SUBJECT TO?

There are two types of projects that may be subject to the Manual: Small Projects and Regulated Projects (both of which may be subject to trash controls). The distinction between Small Projects and Regulated Projects is based on the amount of impervious surface that is created or replaced. The decision tree, below, may be used to assist in determining the project category.

Types of Controls Projects Are Subject To_Decision Tree

1. Detached single family homes that create and/or replace 2,500 sq ft. or more of impervious surface are considered small projects.

2. Projects that do not fall within the Phase II Permit Area subject to this manual as shown in Figure 2-1 may still be subject to the requirements of this manual as determined by the jurisdiction.

3. Other State Water Resources Control Board General Orders may apply to the project (e.g., Construction General Permit or Industrial General Permit).
