Stormwater Diversions & Easements
When your site has no lawful point of discharge, or council's pipe runs through the middle of it, the drainage problem becomes a legal one too.
What you receive
Stormwater diversion or extension design plan
Hydraulic Grade Line analysis of the existing and proposed system
Inter-allotment drainage design
Technical documentation supporting an easement application
Integration into your Stormwater Management Plan
How we do it
Assessment of existing council and inter-allotment drainage capacity
Design of diversions, extensions and new connections
Hydrologic and hydraulic modelling of existing and proposed systems
Easement alignment, width and depth determination
Documentation supporting easement creation or a section 88B instrument
Negotiation support with council engineers, and technical input where a neighbouring-property easement is required
When you need it
Sites with no direct fall to the street, landlocked and battle-axe allotments, existing council drainage crossing the site, subdivisions creating new lots, or a consent condition requiring an easement to drain water.
