Blue Green Infrastructure Design Typologies for Streetscapes
These design typologies will assist those planning, designing, constructing and maintaining blue green infrastructure assets for streetscapes.
Blue Green Infrastructure contains vegetation that is passively irrigated with stormwater. These include Water Sensitive Urban Design features like raingardens and raingarden tree pits which reduce pollution entering our local waterways.
These design typologies will assist those planning, designing, constructing and maintaining blue green infrastructure assets for streetscapes. Each typology contains relevant design drawings, design advice, MUSIC modelling parameters, recommended construction hold points and ongoing maintenance schedules.
The development of these typologies has been assisted by Melbourne Water as part of the Living Rivers Program.
The purpose of this information is to assist you in developing your Blue Green Infrastructure project. Some of the drawings associated with this typology are not yet included in the Engineering Standard Drawings. We are currently identifying sites for potential trials. You will need to work with our Infrastructure and Assets team and Urban Forest team to finalise your design and obtain relevant approvals.
Typology 2 – Rectangular back of kerb raingarden
Rectangular back of kerb raingardens are suitable to use when there is at least 1.2 metres of space behind the back of kerb that is not essential for pedestrian movement or other street functions.
Typology 3 - Covered back of kerb raingarden tree pit
Covered back of kerb raingarden tree pits are suitable for heavily used footpaths where there is limited space behind the back of kerb that is not essential for pedestrian movement or other street functions.
Typology 4 - Large outstand raingarden
Large outstand raingardens are suitable to use in streets with 90-degree kerbside parking and a space for a raingarden adjacent to car parking bays. A spoon drain in the road intercepts stormwater runoff flowing towards the kerb and directs it into a raingarden constructed between 90-degree car parks.
Typology 5 - Small outstand raingarden
Small outstand raingardens are suitable to use in streets with parallel kerbside parking and space for a raingarden adjacent to car parking bays. A spoon drain in the road intercepts stormwater runoff flowing towards the kerb and directs it into a raingarden constructed between parallel parks.
Typology 6 – Bluestone channel raingarden tree pit
Bluestone channel raingarden tree pits are suitable to use in narrow, low speed streets where a tree can be accommodated within a gutter channel consisting of a strip of bluestone pavers.
Typology 7 – Side of road passive irrigation tree trench
Side of road passive irrigation tree trenches are suitable to use in footpaths where multiple new trees are being installed in the footpath and it is possible to install a structural soil trench between the trees. The surface around the tree is flush with the footpath surface so there is minimal impact on the width of footpath available for pedestrians.
Typology 9 – Outstand with surrounding permeable pavement
Outstands with surrounding permeable pavement are suitable to use in streets with kerbside parking and space for a tree to be planted adjacent to the parking bays.
Typology 10 - Permeable Footpath
Permeable footpaths are suitable for use where there is a footpath above a current or planned vegetation root zone. Permeable footpaths support vegetation by increasing the soil moisture and oxygen content.
