Perimeter drainage planning for White Rock hillside lots

Four planning paths: perimeter replacement, sump systems, camera access, and surface drainage. Each detail page explains common fit, scope sequence, cost factors, and questions to ask. Start with the topic that matches the symptom, or send an inquiry if you are unsure.

Perimeter Drain Replacement

Review excavation, filter-protected pipe, clean gravel, access, and discharge when a perimeter line may be clogged or collapsed.

Scope questions for full or partial replacement when accessible evidence suggests silt, roots, offsets, or collapse.

On a sloped property, the symptom may sit below the source. A replacement plan should document the suspected failure, excavation access, pipe and filter protection, cleanouts, the lawful discharge route, backfill, finished grade, and restoration. Camera evidence can help when a usable access point exists, but it does not make every buried section visible.

Sump Pump Installation

Compare sump pits, primary pumps, controls, check valves, alarms, and backup where gravity alone may not provide a reliable outlet.

Planning questions for pits, pumps, controls, backup power, check valves, alarms, and discharge.

A sump can be part of the drainage path when gravity is insufficient, but pump size alone does not explain performance. A careful review considers the basin, feeder lines, cycling behaviour, controls, check valves, power-loss risk, and where discharged water goes. The final route should avoid sending water back toward the footing.

Drain Camera Inspection

Understand what a camera can and cannot show inside an accessible perimeter line before major excavation is approved.

Understand reachable pipe evidence and its limits before major excavation is authorized.

When a cleanout or other suitable entry exists, a camera may show roots, silt, offsets, standing water, or collapse along the reachable run. Not every perimeter system is accessible, and a camera view is not proof of unseen sections. Ask that video findings, limitations, and the reason for any proposed repair or replacement be written into the scope.

Surface Drainage Corrections

Review reverse grade, downspout discharge, low spots, and lower-yard ponding that may increase water beside a foundation.

Review reverse grade, downspouts, low spots, and the lawful surface-water route.

Downspouts ending beside a wall, low spots, and reverse grade can add water at the foundation during rain. Surface corrections may be worth assessing before excavation, but they are not a substitute for a failed perimeter line. A written plan should identify where roof and surface water can lawfully go and how the finished grade will remain stable.
