Investigate What Is Under and Beside the Asphalt

Water, unsupported edges and movement below the surface can interact. Record the relationship before selecting a finish.

001 / Guide section

Follow runoff routes

Record where water enters the paved area, where it slows, how it crosses or leaves and what changes after significant rain. Roof discharge and adjacent ground can matter as much as the paved grade.

  • Up-slope water sources
  • Ponding and clearing time
  • Low edge or outlet
  • Downhill receiving area
002 / Guide section

Read the edge condition

Cracking or breakup along an unconfined edge can accompany shoulder erosion, vehicle loading or loss of adjacent support. Photograph both the asphalt and the material beside it.

  • Edge drop-off
  • Shoulder erosion
  • Vegetation or root pressure
  • Turning loads near the edge
003 / Guide section

Map movement and soft zones

Depressions, recurring repairs and soft areas should become location-specific questions about excavation, base correction and drainage—not assumptions about a uniform section.

  • Location and approximate size
  • Change after rainfall
  • Relationship to wheel paths
  • Nearby repairs or utilities
004 / Guide section

Keep ditches and culverts inside the boundary

A ditch, culvert or public approach can trigger separate permissions or design questions. Confirm current City requirements for the exact address and scope before proposing changes.

  • Ownership and jurisdiction
  • Public versus private connection
  • Outlet and downstream impact
  • Qualified design review when needed
Local evidence boundary

The City describes condition management and inspection for municipal roads. It supports condition-led thinking, but it is not a private-driveway specification and does not imply municipal affiliation. City of Maple Ridge pavement-program context ↗
