The back part 5-6 ft of the lawn where it meets the neighbors propertyproper to hold some water for a few days and almost always stays damp . Both back yards drain towards this area and then are graded slightly from east to west across the back. There is a sewer drain about 100 ft from the corner of our lot at the far back corner of the next lot (currently has not been purchased/built on) to the West (slightly downhill from our yard) and I think our lots are designed to flow that way. ​​​​​​Landscaper says our grade is fine. It is all hard clay around here . So here are the options we are considering .Looking for feedback on which might work or other suggestions. here is the area in question Option 1) lie down stones over the top of the wet area coming out 5-6 ft from the fence creating kind of a dry creek bed . Across the whole back of the property. Something like pictured below but maybe without the edgers on the fence side. Would this look ok? Would this help keep mosquitos down as any standing water would be under the rocks? Do we have to dig down and remove the turf or just kill what grass there is an put down the stone? example: Option 2: run a French drain across the wet area . I'm assuming this would have to run all the way across our property and the neighboring property and dump into the sewer drain? Option 3: have 1 or 2 deep holes dug and filled with stone then covered with top soil. Essentially dry wells. Could also use the nds flo well? How big do the holes need to be for this option? For diy what kind of equipment would one use to dig that deep? Which option is best? Is there a better idea? Thank you

We just moved into a 20 year old home with an existing sprinkler system that does not work properly. It has an Orbit timer controller with four zones. There are four zones around the house. Three zones for above ground sprinklers and a fourth zone for drip or shrub watering. However there are six zone valves wired into the system. I think it was originally a two zone system and then two more zones were added. Just a guess. The first photo is zones 1 & 3. You can see a Hunter PGV valve "A" in the center with 2 red wires. Then there is a Rainbird valve on either side. My guess is the water needs to go through the Hunter valve to send it to either of the Rainbird valves. So, I assume to operate zone 1 on the left I have to open both the Hunter valve "A" and the left Rainbird valve for that zone to get water. Similarly, if the right Rainbird valve is zone 3 then again I have to power both the Hunter "A" and the right Rainbird valve to get water to zone 3. The next photo is the second set of zone valves. Looks just like the first photo. There is a Hunter PGV "B" in the center and a Rainbird valve on either side. The left Rainbird is for zone 4 and the other is for zone 2. So, again I am guessing I need to power both the Hunter "B" and the left Rainbird valve for zone 4 and the Hunter and the right Rainbird for zone 2. So, how do I wire it? Can I wire the Hunter valve and the appropriate zone together? If I do then the Hunter valves are wired to two different zones. Meaning zone 1 gets Hunter "A" and Rainbird 1. Zone 2 gets Hunter "B" and Rainbird 2. Then zone 3 gets Hunter "A" and Rainbird 3. Zone 4 gets Hunter "B" and Rainbird 4. Will this work since the Hunter valves are each wired to two different zones? Or is there a way to just have both of the Hunter valves always open? What is the correct way to do this?
