Every Level AI run produces a lot report: one row for each lot, showing how it drains, the level of the house pad, how much it is cut or filled, the lot's flattest and steepest grades, and a Checks column that lists every limit the lot breaks.
Where to find it
In Civil 3D — Tools panel ▸ Tools ▸ Lot Report opens the table in a pane.
In the Allsite.ai web app — Design ▸ Design data ▸ Lot report, for the project's latest results.
As a CSV — the download button saves the visible tables.
Before you read the numbers
One row is one lot. Only normal lots are listed — reserves, roads and joint access lots are not. Rows run in lot-number order.
It is the latest Level AI results run. The table is replaced each time results are generated, so it always matches the design you loaded last.
Check the units. Lengths and levels follow your project units: m and RL (m) on a metric project, ft and RL (ft) on an imperial one. Grades are always percentages.
A dash means there is nothing to report for that cell — for example no building on a vacant lot.
The Summary and the Lots table. Numbered markers: 1 Lot, 2 Type, 3 Drainage, 4 FFL, 5 Cut, 6 Front level, 7 Min grade, 8 Checks.
The Summary
Item | What it tells you |
Result set | The Level AI results set the table was made from. |
Lots | How many lots are in the table. |
Drainage A (front), B (split), C (rear) | How many lots drain each way. A type only appears if some lot uses it. |
Lots with checks | How many lots have a limit broken. Lots that were not measured are not counted here. |
Lots not measured | Lots where no grade could be measured. See Not measured below. |
The Lots table
Column | What it is |
Lot | The lot's parcel number. |
Type | The lot type Level AI was given, for example SINGLE FAMILY TYPE B. The trailing TYPE A / B / C is the drainage the lot was asked for. Where the lot type is blank, the parcel's category is shown instead. |
Drainage | How the lot actually drains after the run. A (front) falls to the front of the lot; B (split) crests part-way along and falls both ways; C (rear) falls to the rear. The requested and delivered types can differ. Any other value is shown as it is. |
FFL | The finished floor level of the lot's largest building, as a level (RL). A dash for a vacant lot. |
Cut, Fill | How deep the building pad is cut into, or filled above, the existing ground under the footprint. These are depths, not volumes, and never negative. On a sloping pad both can be non-zero: the lowest corner is in fill and the highest in cut. The earthworks volumes are on the Cutfill page (see Interpretting Cut-fill table data). |
Front level, Rear level | The lowest finished level along the lot's front boundary and along its rear boundary. They describe the boundary, not the pad. |
Min grade, Max grade | The flattest and steepest grade measured on the lot, as a percentage. Grades are measured along the grade lines Level AI draws on the lot, front to back and along the sides, and stop at retaining walls. |
Checks | Every limit the lot breaks, separated by semicolons. A dash means the lot passes. |
Checks
Message | What it means |
Min grade X% < Y% | The flattest grade on the lot is below the minimum allowed. The water may not drain. |
Front yard / Side yard / Rear yard X% > Y% | The steepest grade in that part of the lot is over that yard's limit. |
Protective slope X% > Y% | The slope from the building to the toe of the protective slope is over its limit. |
Side swale X% > Y% | The swale along the side of the lot is steeper than the flow line slope limit. |
FFL X < min Y | The floor level is below the lowest allowed floor level for the building. |
Fill X m > Y m, Cut X m > Y m | The pad is cut or filled by more than the building allows. A limit of zero means no cut or fill is allowed. |
Not measured | No grade line could be drawn on the lot, so there are no grades to check. Corner lots and pads that wrap around the perimeter are not measured today. A not-measured lot can still show a floor level, cut or fill message after it. |
Only the worst grade in each part of the lot is reported, and each comparison is made at the precision shown, so you will never see a message like “8.00% > 8.00%”.
Settings that change these numbers
Setting | What it changes |
Front, side and rear yard slope maximum; protective slope maximum; flow line slope maximum; default absolute minimum grade (Lot settings) | The limits behind the grade messages. A lot's own values override the project settings. |
Per-lot values on the lot (maximum cut and fill, minimum floor level, minimum and maximum grade, lot type) | The limits for that lot only. |
Buildings, retaining walls and the proposed surface | FFL, Cut and Fill, and where grade lines stop. |
Project units | Every length and level. |
Common questions
The page is empty.
No Level AI results have been generated for this project yet, or the latest results had no proposed surface to measure. Run Level AI and load the results.
Why does a lot say Not measured?
No grade line could be drawn on it. Corner lots are the usual case.
Why do Type and Drainage disagree?
Type shows what the lot was asked for; Drainage shows what the design delivered. If they differ, the surrounding levels would not let the lot drain the requested way.
Why does Cut show a value when the lot looks like fill?
Cut and Fill are measured at the building footprint against the ground under it. A sloping pad can need both.
Where are lot area and frontage?
The table does not include them. Retaining walls and driveways are not in it either.
