Wash Out Area Details (Erosion Control)

Wash Out Area Details (Erosion Control)

Wash Out Area Details (Erosion Control)

(OP)
I am practicing in the state of Georgia.  Our Erosion and Sediment Control Manual vaguely describes having truck/ trailer wash out areas near Contruction entrance/exits (Co).  Does anyone have specificaitons, detail drawings, or a reference of where to find a WASH OUT AREA detail?  

Thanks!

RE: Wash Out Area Details (Erosion Control)

you really don't need much of a detail.  just a gravel pad for the truck to stop on at the driveway so mud can be sprayed off and not tracked on the streets.  Just make sure the wash water drains back onto the site.

RE: Wash Out Area Details (Erosion Control)

we'd always make an area that had a few loads of #34 stone but had the grades sloping toward the detention pond. long hose and good nozzle to help spray off mud. also put aggregate down from there to construction entrance (doesn't make sense to wash off tires then drive right back in the mud).

there's a detail in that little green book or in the manual they give you when you take the 1A or 1B certification class if i remember correctly. maybe one of these would help

I'd bet the washout area is for concrete truck spoils. CA DOT has a standard whick basically a sump made from staked haybales with a polyprope liner laid within.

RE: Wash Out Area Details (Erosion Control)

I am with Hoagie, sounds like you are speaking about concrete truck wash out area(s) ( after discharging load & before heading back to plant) we use silt fencing,placed in circular pattern, to capture  until it sets up, then haul off.  Construction  Exit would be an area of stone etc. where muddy vehicles can be washed off while accessing the project to limit the "tracking" of mud etc. onto the roadway.

RE: Wash Out Area Details (Erosion Control)

In NC we call them mud mats and you just put down oversize stone something larger than 57 and smaller than surge.  As far a concrete goes I would always give the driver an option to dump on site because I have heard some pretty nasty stories about what those guys will do @ quitting time with extra crete.

Please explain the NC terms:  oversize stone something larger than 57 and smaller than surge.

 I am in Arizona.

Thank you.  

RE: Wash Out Area Details (Erosion Control)

#3 sized stone works well.
