Rock turns up a median 22 ft down
From 1,565 depth-to-rock records inside Stowe (Vermont DEC well records). Logs cluster where people drill wells and bore for roads, so treat this as the town’s pattern, not a site answer.
Half of Stowe's logs reach rock between 10 and 47 ft
Depth to bedrock: 10th–90th percentile whisker, middle-half box, median tick; dashed line = Vermont median.

Rock within 10 ft
29%
of logs (34% across Vermont). Shallow rock means ledge in excavations, refusal for driven piles and rock anchors rather than soil nails; deep ground means taller shoring and more groundwater. 23% of logs here go past 50 ft.
Mapped landslides
31
19 mass failure · 12 landslide. Inventory points from the USGS U.S. Landslide Inventory; many are prehistoric slides mapped from lidar.
03 · Dams & disasters
Lamoille County has drawn $46.8M in federal disaster repair since 2010
FEMA Public Assistance is reported by county, so the figure below is Lamoille County-wide context, not a Stowe number.

$46.8M
Federal share obligated across 502 projects in 19 declared disasters since 2010. The largest category is public utilities (48%); roads & bridges took $14.5M.

Permits in the city’s open-data portal that mention retaining walls, excavation or foundations. Only a handful of portals are read, so this counts what is published, not everything built.

Where these numbers come from
Method, sources & caveats
Stowe is the Census county subdivision 5001570525 (Lamoille County). Every record is placed here by its coordinates, not by the place name the source uses.
- Towns are Census county subdivisions: cities, towns, plantations, and Maine/New Hampshire unorganized territories and townships. Every record is placed in a town by its coordinates (point-in-polygon), not by the source's own place label — so a bridge in Roxbury counts for Boston and a well in 'North Waltham' counts for Waltham.
- Bridges: FHWA NBI 2025, highway structures ≥ 20 ft including large culverts. 'Poor' is FHWA's good/fair/poor rating (lowest of deck, superstructure, substructure or culvert ≤ 4). Percent-poor is shown only for towns with at least 5 structures.
- Depth to bedrock is the median of driller- and boring-reported depths in the town, shown only where at least 10 logs exist. Water-well logs over-sample rural lots and hilltops; one town median never describes a particular site.
- Bedrock depths use the same state databases and filters as the Bedrock & soils module (bedrock wells and borings that reached rock, 0 < depth ≤ 400 ft, exact re-filings dropped), but every log is placed in a town by its coordinates rather than the driller's town field, so town counts can differ slightly between the two pages. Connecticut and Rhode Island have no statewide public well-log database with depths.
- Dams: only high-hazard-potential dams whose latest condition assessment is Poor or Unsatisfactory are counted (live NID). Connecticut and Rhode Island assessments may lag.
- FEMA Public Assistance dollars are federal share obligated for disasters declared since 2010, reported by county — they are county context, not a town figure.
- Grant awards are Massachusetts only (EEA Dam & Seawall program, MVP Action grants, CZM Coastal Resilience). Other states' programs are not yet included.
- Ground-related permit counts cover only the municipal portals the pipeline reads (Boston, Cambridge, Somerville, Worcester, Framingham, Providence, Portsmouth, Hartford and a few others) — an absent count means 'not covered', not zero.
