How do you get excavated material from the cut area to the fill area without driving heavy equipment over the septic system?
A 2nd driveway for the shop off the main road? different from the house? Here you wouldnt be able to do that, because of the 911 system,they dont allow 2 driveways for one address might want to be sure you can do that..people do have 2 driveways,around here but they are grandfathered in
My shop i had to cut into a hill about 5 feet, i hired a guy with an excavator to do the job,still took a few days to prepare my site, we also have rock around here, i had to rent a mama jama tracked jack hammer to break them up too
How do you get excavated material from the cut area to the fill area without driving heavy equipment over the septic system?
A couple of things.
First, in most jurisdictions you cannot regrade or contour your property so that it increases the natural flow and quantity of water that goes from your property to that of a neighbor. So that pipe is not a good idea.
Secondly, when I design a site, I try to minimize changes to the existing contours as much as possible. And I avoid retaining walls at all costs. They are expensive to build in a way that will allow water to pass around them and avoid having hydrostatic pressure topple them.
I always place buildings where no cut is required, except the removal of organic material. Then I create a building pad with compacted fill, that raises the finish floor elevation 6" to 8" above the highest adjacent grade.
The beauty of your site is the rolling terrain. I would be careful not to turn it into a flat parking lot or bowling green. In fact, I would landscape it in ways that highlighted the natural beauty of it's sloping features.
And instead of a big block of a giant industrial looking garage, I would be looking for ways to break it into a more variegated and residential look.
Just a thought.
Additional:
I just took a longer look at your site. What is the size and scope of the intended shop/garage space? If it is to be a very large, active and noisy space, then a detached location is needed. If it is to mostly add garage space with some additional space for shop activities, then I would simply add on to the existing garage. The present plan uses up half your lot, between drive and shop.
Another question.
Why not put the new shop even with the existing house?
That would shorten the driveway considerably and turn all the space behind the shop into private back yard area. And there is still adequate room between the shop and house to access that back yard space. Might even put a garage door on the back to create a pass through garage.
What you are proposing right now, has a driveway almost long enough for a runway.
One more idea.
When you fill enough to get a reasonable driveway along that property line, you will block the flow of any potential water unless you install a culvert under it.
So I would take a problem and make it a feature.
In the low point where water could collect, I would create a dry pond, or even a wet pond. Make it a focal point of the front yard. You could even curve the drive around one side of it to create visual interest and reflect the curve of the existing drive. I would make the entrance from the road a little ways from the property line, not right at the line. This would give space to plant trees and shrubs to block views of the garage from the road. Likewise, I would plant a screen along the property line.
The curved drive would also require less fill since it would follow a higher contour. And move the shop away from the property line a bit too. This will allow future additions on the side.
And when you excavate the low point to make a true depression for a pond, the spoils can be used for fill for the drive right adjacent to that. You might not even need to get material from the play area. What you are creating is a retention pond, dressed up as a dry or wet pond "Landscape feature".
Something like this:
i only included a pipe under drive not the 80 foot you were talking about. i couldnt reallly understand that one. It seemed like you could get positive grade on the surface and not need to pipe it but hard to tell.
you will need site plan. They are expensive. Minor is 5 to 7k and full which is what you might need is like 10k.
I am in VA and in our county you can only disturb 2500 sf and change grade 18" before you need a permit. That means just your driveway in back would need to be done in two parts maybe three because you cut out tsoil and fill with stone and cut material goes? outside drive? part of B section to fill?
Anyway, you have too many neighbors to do under the radar unless all your neighbors are GOOD friends.
If you get plan you should get it for your shop you want to build and drive and dirt and all at once.
One in our county VA you can only build a 1000 sf building on a walk through permit. your 30x40 would need permit and site plan because they add 10 feet to each side and since you need to access it you would disturb ten foot lane to get to it. This puts you way over.
So if you get permit for the dirt move then you have to do it all over again for the drive and the garage.
If you have to bite a bullet do it once.
What is your area of cut? 100 by 60? if so at average 2 foot cut thats 450 cyards of dirt. 45 dump truck loads. Day or two with the right equimpment. Not a tractor or a backhoe. forever with tractor and a week with backhoe including move to new site. probably small truck best when ground is dry.
I would get site plan even if only to site the building footprint this would get site plan portion done and then it is just your architectural stuff needed.
I would cut high area fill low area cut in drive re grade and stone driveway and rough area for pad for garage and stone it. finish grade it all and see the piss out of it.
All of that could be done in a few days with an excavator, track bobcat and truck and roller (for stone at least). If you can truck cut to fill area. Probably need it dry and only if you have good ground that wont rut up with traffic.
Track bobcat should be 750 a day (10 hour)
Excavator from 1000 to 1400 a day maybe plus move
roller one time shot for 1000
dump truck for 750 a day.
so for 8 or 9 k you should be able to cut and fill a and b cut in driveway cut in "flat" area for parking and garage area and install stone and compact. Plus 2 k for stone and whatever for a cmp (pipe) or the plastic under drive ($300) and some seeding.
Total 12k for dirt and stone and pipe then you seed and straw it.
Plus you will have silt fence for 600 to 800 feet at a couple bucks a foot.
plus your site plan.
Let me know if area is correct.
I like the way you think! Always churning and running through possibilities!
I did this with a kitchen remodel in a previous house. I thought about it for 5 years before finally pulling the trigger. I shared my layout idea with the kitchen architect (who was nice but had that "I am the expert" aura) and he stated he would give me some ideas that he was sure would be awesome. He came back and said he can't improve on what I came up with.
Not that I was surprised - I had been living in the house for 5+ years and thinking about constantly.
Back to the yard - yes a culvert (pipe) would be under the driveway to the back to allow for the natural waterway.
I have thought about extending the two parking spots out front into a circular driveway:
![]()
My only concern about messing with any area around the trees in front of the house, is the root system. I can only bring in 1-2" of topsoil without harming the trees. Any kind of pond or circular driveway would more than like harm them and we want to keep them....
Ayuh,.... My thought as well,....
Put a culvert at the road, where the driveway starts, 'n control the water, at the surface out to it with a swale along side the driveway,...
bczygan - I like the design! I will be sharing it with my wife. Only reservation with it is the size of the garage - 12ft ceilings for a lift and attic trusses will seem like another full size house between mine and the neighbor. Being in the back corner keeps it more of a "secondary building". (but it would be on higher ground back there and look larger in height - sheesh, always something)
A couple of things to make it seem a subsidiary structure to the main structure, and not a house in it's own right.
Step it back slightly from the main house.
Place plantings that will eventually block a view of the the entire building from any vantage point on the road. In other words, you only get glances of parts of the garage.
Set it slightly down slope from the house.
The curved drive and pond used as a focal point draw attention away from it.
BTW, If you extend a drive from the existing 2 parking spaces to this new garage, and it's driveway, you can get a complete circle in and out. Or you can eliminate the separate drive for the garage. It could even be rotated 90 degrees so the door faced the house.
And the reason I come up with lots of alternatives.....that is the design process you go through as an Architectural Designer. You identify all the existing conditions, and add to that all the needs and desires of the client. Then you take the requirements of the city or other jurisdiction and throw them in the mix. BTW, what are your setbacks here? And you temper all this with budget considerations, local Architectural styles and then work through all the possibilities, measuring and comparing until you get a balanced solution.
It's a similar process for designing anything.

Actually there would be a culvert right at the road also. There is a road run-off dip 2 feet off the road. In the below pic there would be on on the other side of the leland cypress along the road:
![]()
The dotted red lines would be the 80 ft pipe across the side yard from the trees to the neighbors yard. I could theoretically just do a pipe under the driveway. but my thinking is getting a nice even gentle slope from the back of the property to the road (for the side yard only - can't affect the tree area) since the tree area is the low spot I need the pipe to siphon off any water from the tree area to the low spot at the neighbors yard. The pipe across the whole length would be if I grade the side area to match the thin yellow line (fill in the entire "dip" across the side yard)
OP . . . re-think everything using Bczygan idea as starting point. He's got great ideas of using slope as advantage to add interest to property.
However, OP you've been delusional on two things:
a) NEVER, ever, never going to be able to put 80 ft pipe dumping water to neighbor's property - - - - NOT going to be allowed.
b) Also delusional talk to have heavy equipment driving over septic field. Do NOT do it, as you're just asking for trouble. Avoid driving over at all costs.
Consider also NOT having hard driveway (ie asphalt) that entire length of property to the garage. If you kept new garage reasonable distance from road, you could use pavers which would still allow water to permeate the soil and are considered "temporary" for tax purposes (thus not taxable). That giant asphalt driveway you were thinking will cost you big time in Real Estate taxes every year to eternity.
Ayuh,.... You can still forget about the 80' of pipe, just grade the entire hill, string line straight downhill to the point of the raodside culvert,....
All of any surface water would pitch to the culvert, or at worst flow over the new driveway,...
That's the purpose of Boxin' in the driveway,...
Insteada built Up, it's built In, so water can flow wherever it's always flowed,...
You've got the drop to work with,...
The pipe will funnel the water,... that could cause erosion on the neighbor,..
A gradual slope will disperse the water, so no flows, no erosion,...
Buy the 20' culvert for the road entrance,...
Save the money on the 80'er, 'n just regrade the surface,...
Bondo - yes the idea is string line straight from the back yard to the trees(street) and most of any water would run that way. But look at this pic. I did the slope in the pink arrows:
![]()
By the red wagon, you see the ground starts sloping toward the trees. The orange circle area is the lowest spot on the property. If I string line straight to match the thin yellow line, any water in orange is effectively trapped. That is the reason for the pipe all the way across. I could just build up the swell under the driveway and have a small pipe there. But the original idea is to take the 400 cu. yards of dirt from the back yard and fill the whole swell to "string line" straight and have the pipe "replace" the swell for any potential overflow from the orange area. I have not altered the water flow in anyway. If we had 2 feet of water dumped today, it would rush from the orange area, down the swell, and into the swell in the neighbors yard, under his driveway and away it goes.
Thanks again everyone for taking the time to respond and engage. It is very much appreciated and you all are giving me lots of perspectives and things to think about!
Ayuh,... That's also how I see it,... but the 80' pipe is unnecessary,...
If the tiny hump where the little shrubs are, out by the road, is cut down, 'n pushed into the swale(not a swell),....
The water will most likely perk into the ground, 'n not "Run" anywhere,...
But,... in a Torrential downpour, it could flow to the road, 'n away,....
That way, the guy next door can only bytch at the town, for the road drainage, 'n will have No recourse against You, for divertin' any water,...
You'd end up with a tiny bit of swale through, from the low spot at the trees to the right, over to the left toward the new drive, exitin' the lot to the right of the new drive,...
Ya don't need to waste the money on 80' of pipe,...
Life would be so much easier if you put the garage North of the house.
Hope you REALLY can think outside-the-box and consider other options. Thus far, appears you are NOT able to do that. Seem hard headed when experts like Bczygan tell you 80 ft solid steel pipe directly pointed at neighbor's property will NOT fly with any approval process. You'll be effectively creating funnel (ie the steel tube) whereas before a wide surface area absorbed the water. That funnel is directly pointed to the neighbor's property . . . just the PERCEPTION (ie the look and feel) of that 80 ft pipe will NEVER fly by the approval board!!
If however, you have significant political and monetary "pull" then you might "try" your 80 ft pipe idea (ie build it and hope for forgiveness later). However, if I was your neighbor I'd have it tore out after you built it with help of Fed's to overrule local board. Thus, you'd be paying for dirt moving at least TWICE, and maybe THREE times!
Now alternatively, if you dug pond down at edge of property (on your land) and had the 80 ft pipe dump into your own runoff pond, then it "might" fly . . . however, only if that pond didn't frequently overflow onto the neighbor's property. Same Catch 22 applies that you'll not be able to make changes that effectively create new concentrated water flows onto a neighbor's property.
All this guessing is just that a WAG. You'll need topographical surveys by a professional as other GJer's have indicated. Good luck.
