    This area is low land that really has nowhere to drain to.
    Any ideas of how to help the area from staying flooded for so long after rain?

    I was wondering if topdressing a inch or so of sand would help it drain better.
    any thoughts?
    see pictures. The area slopes downward towards the truck way in the back of picture 1 ,and levels off and pools.

    I can do a rain garden for some areas but don't know how or if at all can help the large level areas.

    A drain tile would solve the problem. It looks like there is a drop off way in the back of the property, so you could make it exit there.

    The only problem would be on the near side (of pics) of the driveway and being able to run the pipe under the driveway.

    What's your soil like down there? We have done a dry well with an area like that in sandy soil that works well. If you have clay, run a long french drain into the woods.

    What he said...you could also find someone to auger deep holes and fill with gravel to act as catch basins and cap with dirt and seed of course for the water to drain into

    Down here you can not drain your water onto another person property. Yes I know its just woods but here its not legal just like dumping limbs on the property.I would go with a dry well also or a small fish pond.

    Sand does not help drainage into soil that won't take in water. It will displace water if put on the surface.

    Sand has bigger voids between particles so that WHEN it is the soil it can hold more water than soil with smaller voids and water passes through it more easily.

    The idea of gravel filled trenches or holes is good because the spaces between the gravel can hold a lot of water until the soil has a chance to absorb it.

    You can also use large vertical pipes with holes drilled all around and stone outside. You can get a rim and grate for the pipe to make it a leaching catch basin out of it. The pipe holds a lot of water. the bigger hole for gravel increases the surface area of the existing soil to absorb the water. The sides of the hole will absorb water as of course the bottom of the hole does, too. More surface = more absorption. More voids = more storage. (inside of pipe is total void)

    Checkout NDS, ADS or ACO for their drainage products. They all have solutions to your problem.

    If there is a porous soil layer within easy digging depth, french drains, vertical drain pipe or NDS Flo-wells would work well. If these are not practical solutions, pipe it to somewhere that it won't be an issue, perhaps create a rain garden. You can determine the porosity of the soil by performing a percolation test, or check the soil map of the USDA. http://websoilsurvey.nrcs.usda.gov/app/
    A simple and effective poor man's perk test is to dig down a few feet with a post hole digger, manual works well, and fill the holes with water and monitor the time it takes for the water to drain out. Anything longer than a day will be a problem, but depending on the time of year and the soil texture; you examine this as you dig the holes, less than 12 hours is good, and quicker is better. If the digging is to tough with a post hole digger, not just because of rocks, you may want to reassess the dry well idea.

    The simple solution is to get the standing water away from the sidewalk and driveway and get it back into the aquifer or watershed that your property is a part of. The idea of sand on top of the existing soil will act as a good filter for contaminants, but it won't make the water go away any faster.

    Is some of that water coming from the downspouts at the house? If so, handle them first, hopefully into their own dry wells or piped away, downhill. I would think about a channel drain in the driveway at the natural low point and pipe that away to a dry well or open air, downhill.

    Whats a channel drain? is that like a drain that is installed in the driveway itself(cut the concrete and install?

    Also won't sand on top of the area make it firmer to walk on??

    The problem with this property is how low lying it is. It is so low that the water table is not too far down, so it's almost like a pond.
    they may just have to live with it and deal with the areas they occupy most.

    thanks for ideas..
