**New construction requirements are coming**

A SWPPP is required for construction sites greater than one acre in size (disturbed land area). Otherwise, an Erosion Control Plan is required. If your project requires a SWPPP, the County of Orange has BMP information as well as a SWPPP template available. Call Will Holoman at 949-497-0781 for more details on the City's SWPPP program.

From the Regional Board's construction program website:

Dischargers whose projects disturb 1 or more acres of soil or whose projects disturb less than 1 acre but are part of a larger common plan of development that in total disturbs 1 or more acres, are required to obtain coverage under the General Permit for Discharges of Storm Water Associated with Construction Activity (Construction General Permit, 99-08-DWQ). Construction activity subject to this permit includes clearing, grading and disturbances to the ground such as stockpiling, or excavation, but does not include regular maintenance activities performed to restore the original line, grade, or capacity of the facility.

The Construction General Permit requires the development and implementation of a Storm Water Pollution Prevention Plan (SWPPP). The SWPPP should contain a site map(s) which shows the construction site perimeter, existing and proposed buildings, lots, roadways, storm water collection and discharge points, general topography both before and after construction, and drainage patterns across the project.
