How can you plan for the rainy season?
It’s getting towards the end of September, and Fall is approaching quickly (tomorrow, September 22nd, to be exact). We want to get our clients thinking about preparing for the rainy season. In this two-part series, we will discuss general planning strategies for getting ready for winter. Whether it’s an El Nino or a mild to moderate winter, these steps should help you prepare your site.
Permit requirements: The California Construction Stormwater General Permit requires a combination of sediment and erosion control be in place to contain disturbed soil areas during rain events. Regional Water Quality Control Board staff also strong discourage having too much disturbed area open during the rainy season.
Check out our tips below…
Have rain gauge on-site in an accessible location; not behind locked gate that inspector can’t get to (see our full article on Rain Gauge Tips)
Have your SWPPP Binder with reports on-site; in foreman’s truck, trailer or a waterproof box
Following up with Tip #2, Electronic reports are okay as long as they are quickly accessible via computer in the job trailer or on foreman’s laptop
Make sure SWPPP BMP Drawings are up to date, and modify for winterization plan
Check NOAA.gov for weather forecast daily
Cover as much disturbed soil area as possible
Reduce grading to the minimum
Have a mud-free way to get to the jobsite. Our suggestion, rock or pave roads leading to your site
Avoid opening up new areas that can’t be finished before the rainy season starts
Remove creek diversions and finish waterway work prior to October 15 (or dates set in environmental permits)
