Narrow stalls lead to drivers taking up two spaces .. Try different stall angles to better utilize the lot.

What shape is the existing surface in ? Unless there is extensive rutting and cracking, it may be better to forget all milling and just overlay what's there. If you have to match surface grades ( like at drainage inlets , gutters and driveways) it may be cheaper and faster just to spot mill...

Go to work for the DOT , study job plans and contracts. Inspect job sites. Watch how "designs" get translated into actual on-the-ground activities. Talk to the contractors ; monitor costs and change orders. See how close the final product matches the original design. DOT employment will also...

Is the ground water seepage associated with rainfall or does it occur in dry seasons? Did the appearance of the ground water coincide with any other construction work in the area ? Look for evidence of utility trench backfill settling. If the water is seeping up over the storm drain trench, it’s...

Another spot where a specific address and Google street view would be useful...

And don't forget to add queueing distance and separate turn lanes for trucks exiting your site to get on the highway. And a turn around area between the signal and the security gate for public cars that enter the driveway by mistake.

Maybe divide the ponds to allow one side to be taken out of service and the water level lowered to kill the weed . See http://www.ci.austin.tx.us/news/2007/drawdown_extended.htm

If there is a "one Call" or "call before you dig" service in your area...call that number and ask for the manager. In most cases the underground people will also mark or identify above ground stuff. They can also get you the name and contact of the utility manager

1. Always better to replace what was there with the same stuff to preserve the original engineer's design. 2. On the other hand, if you want to upgrade to current standards, there should be a specific design recommended by the roads controlling authority. In most cases, for dead end roads...

. Ask the client to show you some existing 1:1 slopes in the area with similar soils. Did the slope re-vegetate? Did the slopes erode? Are the slopes mowed ? The client may have experience, but unless he has actual examples, be careful....be very careful

Most top soils contain organic matter that will rot and decay and dissolve when submerged. So even it the soil is compacted, eventually the loss of organic material will allow water to pass thru and drain the pond. Unless the top soil tests as a high clay/ silt content and low organic, I’d...

And make sure you get a contractor who has experience placing asphalt in small, tight confined spaces . Most contractors are used to working in parking lots where there is room to turn dumptrucks and pavers. And make sure the contractor has experience in setting and meeting flater grades ; all...
