Connect to Site Stormwater System is a residential building-planning choice in the Price Your Build estimator. Retaining-wall drainage must relieve water pressure safely and connect to a planned discharge route.
What this option means
Retaining-wall drainage must relieve water pressure safely and connect to a planned discharge route.
Why it affects the estimate
The estimator uses this selection to establish an early allowance. Final cost depends on the approved drawings, site conditions, supplier system, installation method and contractor scope.
Before proceeding
Confirm the engineer’s wall detail, filter media, drainage layer, outlet route, erosion protection and stormwater capacity.
Compare the final specification, exclusions and installation detail against supplier and contractor quotations.
Confirm the relevant professional, municipal and product requirements for the actual project.
