    Need some opinions here. Customer is having water pooling on the walk in front of front door. The yard slopes towards the house. Maybe 2 ft drop over a 30 or 40 ft span from street to house. Forms a sort of "bowl" where the water stands (pic 3). Sediment dried on walkway (pic4). Pictures 1 and 2 are just a more distant view. There really isnt anywhere to run a drain to move the water out of the area. I was thinking of doing a sort of French drain / dry well sort of creation. This would also involve bringing the flower bed along the walkway even with the right side of door (facing house). Bed would be 1.5 to 2 ft wide and about 12 ft wider and would hide the drain. Anyone have some other ideas?

    Can you put a collection drain there, and use gravity to let it drain to the side.

    If gravity is not in your favor, the only real option is a sump pump and catch basic sunk below grade. just need 110v power, and the ability to dig a large hole.

    Can't you put in a French Drain and trench it to the curb outlet?? I think that would be your only option unless they want it re-graded?

    We do alot of jobs like this, and we've found the cheapest, easiest solution is a swale to carry the water from there around the corner of the house, doesnt take much dirt work, and the grate is simple, but your are going to have to grade everything towards the grate.. Another thing, somebody mentioned a pump, you can do that, but we are in the process of trying to move the water away from a house, a very similar situation, and there is a pump there now, but it cant keep up with the water flow, and there doesnt look to be near as much fall as the lot in the pictures...

    The first thing to do is to reduce as much of the sources of water as practicle and possible. Start with a gutter on the porch.

    Second is to investigate re-grading to drain away water on the surface. That can be to continue on or to a retention basin (rain garden, bioswale, or whatever you want to call it).

    Third is to inestigate using catch basins to collect the water. Then to determine if the soil can absorb it efficiently (drywell, leachpit,...) or if there is a place to "daylight" the pipe effectively.

    Would it maybe make sense to plant a bunch of shrubs or something along the front of the house that may absorb a lot of this water??

    No, you are not going to vacuum up a surface water with plants.

    Other things you could do are to reduce compaction and you could even use a soil srfactant in the broader area to help absorb more water.

    Don't think a pump is something they will want to do. The issue is, I believe, the problem area is created by a very slight funnel effect. The swale type idea is what I was leaning towards with the bed extension and closed end "french drain."

    As AGLA stated, determine the soil conditions and permeability. This may have a simple solution if a permeable soil layer is not too deep. Direct whatever water coming from the roof away from this are if possible or run it into french drains or the newer, modular containment & dispersion systems that are much more efficient than rock filled french drains.

    A collection pipe buried under the soil, in a smaller swale, leading to a group of buried, NDS Flo-Wells would be an option if a permeable soil layer is within easy digging depth. You can determine the number of Flo-Wells with a calculator available on the NDS site.
    NDS also sells a corrugated drain pipe wrapped in packing peanuts, sorry I can't remember the product name, but is ideal for catching water under a swale and directing it to open air or a containment/dispersion system.

    The idea of using plants is not out of the question, but not to absorb the water, but as part of a rain garden that will collect the water and allow it to slowly recharge the ground water. There is an excellent list of available rain garden plants that can solve a problem as well as beautify it.
