Site and drainage plans that keep water where it belongs
Water is one of the biggest threats to a home. Poor drainage can cause damp, flooding and soil movement that damages your footings. A good site and drainage plan manages where water goes before it becomes a problem.
What’s in a site and drainage plan?
[CLIENT TO CONFIRM: standard inclusions.]
- Existing and finished ground levels
- Finished floor level of your home
- Cut and fill and any retaining walls
- Stormwater pipes, pits and discharge points
- Rainwater tanks and detention where council requires them
- Paving and surface drainage falls away from the home
- Driveway levels and crossover
Why it matters
Protects your footings
Keeping water away from your home helps keep soil moisture even, which reduces soil movement on reactive sites.
Meets council requirements
Councils have stormwater requirements, and many need to see how water will be managed as part of your application.
Avoids neighbour disputes
Stormwater needs to be directed properly rather than onto neighbouring land. A clear plan helps avoid problems down the track.
Especially important for
- Sloping blocks
- Knockdown rebuilds and infill sites where homes are close together
- Subdivisions and multiple dwellings
- Sites with low points or limited places to discharge stormwater
Part of your engineering package
Site and drainage plans are prepared alongside your footing design and retaining walls, so the levels, structure and drainage all work together.
