Pavers with drainage.

I'm pretty clueless about such things but is concrete with a french drain an option? Or some sort of drain that controls the runoff.

You definitely want a solid surface for the w/c. So either pavers or concrete.

What run off? IMO you need a proper walkway as mentioned maybe pavers it depends on the amount of slope. From what I see I can’t imagine a wheel chair getting past the pool equipement and the thorogh the gate. Take some pics from further back so we can see the whole situation.

mulch with large pavers (walking path pavers, not a solid walkway).

I’m thinking that even with pavers, that is tight for wheelchair.

ideas using Jim's suggestion:

Grade is, or should be, sloping away from your house. It seems to be only about 4' until you hit a fence. Is that your's or the neighbor's? Does the grade continue to slope away from the house on the other side of the fence?

Runoff must run somewhere. As long as you are not concentrating it and dumping it on the neighbor, he should be fine.

It would either be a shredded mulch path, gravel or a paver path. What will work depends on the slope which you are not illustrating well in the photos. You must view across slope, not in line with it, to capture it.

Hello,

I would need to stand in my neighbour's yard to come across the slope, The grade continues to slope away from the fence, which is ours, and into the neighbour's yard. Thank you!

How about decomposed granite?

For a wheel chair, you MUST have a paved path. An option I have used is to 'dish' the paving so that the runoff goes down the centre and to wherever you want to dispose of it. It does mean you get water in your shoes if you're using the path in a heavy

IMO run off to a large degree should be handled by your eavestrough with tha not going intot he neighbors at all. I still need to see pics from the front of the house to this areaand also the actual width of this space

Dig Doug's Designs has great skills.

That ?gas meter? and any buried electrical lines might be an issue as to paving the entire path, though. KNOW what utilities are beneath the soil before digging, especially before digging deep.

Paving the path might also be a problem with servicing anything located in the path related to your pool if there are buried electrical or water lines there.

A solid sloped path in icy weather could be more of a slippery slope than pavers with grass or moss or any ground cover in between.

You might consider creating the gentle slope and then covering it entirely with pebbles packed into the ground as smoothly as possible, with or without a double row of pavers for supporting wheels - filling in with more tiny pebbles as the slope changes with the wear of use. Pebbles could be dug through to get to underground pipes and wires and put back in place, albeit dirty, and covered with a new layer as needed.

Also unclear what you mean about runoff making neighbors upset?.....and ..i too....cannot understand why you would consider your mother using this path in a wheelchair...

@btydrvn this is the only path down to the pool and I would like to be able to include my mother in our family events poolside, rather than having her handicap necessitate her to remain on the upper level. I recognize that this might not be possible, but certainly would try to do everything I could to facilitate it for her happiness. Thank you for your question.

Facilitating your mother’s access should be the #1 goal so don’t give up! Do you know what a step ramp is? A ramp with regular low bumps or steps that are gentle enough to roll over but enough of an impediment to slow a runaway wheelchair or divert storm water runoff. Widely used in nyc parks.

@kitasei2 this is very helpful! Thank you so very much.

Since the priority is your mother's use of the path, bury parallel rows of cap blocks end to end, literally touching each other with their tops level with the top of the ground so rainwater will flow over them and you'll have created concrete tracks for the wheels of the wheel chair. To know where the tracks should go -- take the wheel chair out to the path and find out where the tracks land.

.

How long is this space? Take some measurements and do the math -- buy some blocks.

Home Depot carries a 8" wide 4" thick 16" long cap block $1.38 each.

My limited math math skills suggest : 45 blocks x 16" = 720" or (divided by 12") a total of 60' so you'd get a 30' parallel row of blocks out of that for $62.10 + tax -- and Home Depot will load them in your vehicle for you.

You already have some blocks for creating flower beds -- perhaps you could use those?
