The Southern Downs Regional Council (SDRC) successfully lodged two grant submissions allowing for upgrades to the Stanthorpe Streetscape and Rogers Street carpark. This was a joint initiative of the SDRC and the Queensland Government designed to improve the aesthetics and useability of the Stanthorpe business centre. Council commissioned The Stanthorpe Streetscape Plan, and the report identified the need for a component of the overall streetscape upgrade to include improvements to the stormwater infrastructure as businesses within the CBD were subject to regular inundation.
The Rogers Street carpark was an integral part of the streetscape plan designed to provide more off-street parking with throughways to the main street and shops. GenEng Solutions were initially engaged to develop a design and stormwater report for the construction of a stormwater line from Maryland Street, down Fromes Lane and through the Rogers Street carpark. The recommendations from this report were adopted by Council and used as a basis on which to build further modelling for the Stanthorpe Southern Entry component of the streetscape upgrade. GenEng delivered the following:
- Stormwater modelling to identify peak runoff rates from the contributing catchments for the purpose of calculating preliminary sizes of stormwater infrastructure to reach required immunity levels
- Concept and detailed design for the stormwater upgrade of Maryland and Folkestone Streets (Stanthorpe Southern Entry)
- Detailed design for the Rogers Street carpark (including civil and lighting works)
- Detailed design of the Stanthorpe Southern Entry roundabout including provision of carparking, landscaping opportunities in traffic islands, and stormwater drainage improvements
Approach
As the stormwater design needed to be incorporated into different phases of the streetscape upgrade, close liaison with Council and the urban designers was necessary.
CHALLENGES
The stormwater upgrade was restricted by the presence of adjacent building foundations which required a fit-for-purpose design and the use of alternative construction materials to meet constructability requirements and space limitations.
OUTCOME
Our civil designs fit very well with the urban design resulting in the laneway project winning an IPWEAQ award and the community being able to enjoy a vibrant public space.
