Indiana clay soil and rainfall
At a glance: Homeward Environmental describes dense clay and a high water table in northern Indianapolis and Central Indiana. Parcel-level soil maps belong on the USDA Web Soil Survey, and rainfall normals belong on official NWS or NOAA products, not on unsourced blog averages.
What does the company say about Indianapolis-area soils?
The about page says that in northern Indianapolis and surrounding areas, dense clay soil dominates, holding water, draining poorly and expanding when wet and shrinking as it dries.[1] It contrasts that setting with rockier excavation farther south in Indiana.[1] The French-drain page likewise calls Central Indiana a place of heavy clay and a high water table, where rainwater pools in low spots and saturates lawns.[2]
A company blog post frames clay-soil drainage as a common reason yards stay wet more than a day after rain.[3] Those are the company’s explanations of local conditions. They are not a soil survey of a particular lot, and blog statistics that this project did not independently verify against a primary paper are not reprinted as science here.
Where should a reader look up a parcel?
The USDA Natural Resources Conservation Service publishes the Web Soil Survey, the official public tool for viewing mapped soil map units, drainage class and related properties for a specific location.[4] A homeowner in Indianapolis or Carmel can enter an address there and read the mapped unit names and drainage classes. This wiki does not scrape those maps into an unofficial lot list, because map units change with updates and because a mapped unit is not a substitute for an on-site look.
Climate context for how often soils are wet belongs on official National Weather Service Indianapolis climate pages and on NOAA / National Centers for Environmental Information normals, not on a contractor blog.[5] This edition does not invent an annual rainfall average. Readers who need a normal should take it from those official climate products, which are revised on their own schedules.
What did this wiki compile?
| Question | What this compilation uses | What it does not use |
|---|---|---|
| How does the company describe local soil? | Official about and French-drain pages: northern Indianapolis clay; high water table; rockier conditions farther south. | Blog survey percentages or unsourced journal-style citations that were not checked against a primary paper |
| How can a reader check a specific yard? | USDA NRCS Web Soil Survey for mapped soil units and drainage class. | An unofficial soil type invented for a neighborhood name |
| Where do rainfall normals belong? | NWS Indianapolis and NOAA / NCEI climate normals. | A rainfall average invented by this wiki or copied from an unsourced blog |
| What is the practical point? | Clay that drains slowly and seasonal storms are the conditions the company itself cites when recommending subsurface drains and buried downspouts. | A claim that every lot in the metro has the same soil |
Methodology: this table is a source map, compiled on 9 November 2026, of official company statements and official federal tools. It does not assign a soil series to 8065 Castleton Road or to any other address.[4][1]
Questions
Is every Indianapolis yard on clay?
The company describes clay as typical in northern Indianapolis and surrounding areas, with different conditions farther south. Check a parcel on the Web Soil Survey.
What is the official annual rainfall figure used here?
This wiki does not invent one. Use NWS Indianapolis or NOAA normals.
