Rock turns up a median 30 ft down
From 31 depth-to-rock records inside North Oxford (Maine Geological Survey wells database). Logs cluster where people drill wells and bore for roads, so treat this as the town’s pattern, not a site answer.
Half of North Oxford's logs reach rock between 18 and 50 ft

of logs (40% across Maine). 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.

03 · Dams & disasters
Oxford County has drawn $22.7M in federal disaster repair since 2010
FEMA Public Assistance is reported by county, so the figure below is Oxford County-wide context, not a North Oxford number.
FEMA Public Assistance, Oxford County
$22.7M
Federal share obligated across 392 projects in 7 declared disasters since 2010. The largest category is roads & bridges (70%); roads & bridges took $15.8M.

Where these numbers come from
Method, sources & caveats
North Oxford is the Census county subdivision 2301752575 (Oxford 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.
