Rock turns up a median 20 ft down

From 393 depth-to-rock records inside Cavendish (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 Cavendish's logs reach rock between 7 and 45 ft

Depth to bedrock: 10th–90th percentile whisker, middle-half box, median tick; dashed line = Vermont median.

Rock within 10 ft

38%

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. 21% of logs here go past 50 ft.

Mapped landslides

8

8 mass failure. Inventory points from the USGS U.S. Landslide Inventory; many are prehistoric slides mapped from lidar.

03 · Dams & disasters

Windsor County has drawn $90.5M in federal disaster repair since 2010

FEMA Public Assistance is reported by county, so the figure below is Windsor County-wide context, not a Cavendish number.

FEMA Public Assistance, Windsor County

$90.5M

Federal share obligated across 1,345 projects in 8 declared disasters since 2010. The largest category is roads & bridges (86%); roads & bridges took $77.4M.

Where these numbers come from

Method, sources & caveats

Cavendish is the Census county subdivision 5002712250 (Windsor 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.
