Best type of Rock for Parking Lot?

[Brandon Jack Reneau]

Hello BP!

I am working on developing some land I have into Boat/RV parking. 

That being said....

1) What type of rock did you use? 

2) How was the lot layered?

3) Did you do anything to prevent weeds in the future?

I was considering crushed concrete but I'm not sure if that will be the best choice.

Depends on your soil type

Hill country rock just grade.     

Black soil or sand.

3 inch clean rock or recycled concrete.  4 inches for base.  Wait till it rains then drive something heavy to pack it in.  Then 4 inches or 1 1/2 inch with the fines for the roads.  For the parking I would just use the 3 inch clean.  

Really recommend you use the engineer geogrid fabric for roads. The lay 4 inches of 1 1/2 inch with the fines.   Must be 1 1/2 or larger to work.  Smaller or pea gravel will work thru the mesh.  No potholes ever.  Don’t grade to deep though.

You will get weeds even in rock.  Mix both the 1 year pre emergent and the All kill and spray together. If you’re spraying and it is not dying you have water hemp.  Ask for a spray with strength 10 to 14 on the label and spray higher mix.
