Arborgreen at the Newcastle Inner City Bypass
The Newcastle Inner City Bypass, a project worth millions of dollars in New South Wales, is now showing off Arborgreen’s quality range of timber stakes.
According to the Roads and Maritime Services website, the Rankin Park to Jesmond is the final stage of the Newcastle Inner City Bypass. The bypass is located between Rankin Park and Jesmond, to the west of John Hunter hospital.In June 2014, the New South Wales government said it would complete the $280 million Rankin Park to Jesmond section including the $150 million from Restart NSW to push the project forward.
This section is expected to “provide traffic relief to the surrounding road network, in particular the existing route of Lookout Road, Croudace Street and Newcastle Road”.
The 3.4 kilometre four-lane divided road also included “bridge structures along the road to provide drainage, fauna movements and bushwalker access”. The community was involved in 2007, providing their comments to the development.
A spokesperson from Landscape Solutions, said they did the landscaping, garden preparation and planning for the project. Their job was to fill in the missing link in the Newcastle Inner-City Bypass. They started work on the site in October 2013 and by end of January this year, the site was opened for use.
At the moment, Landscape Solutions continue to maintain the area. “Every now and then, they decide to plant in a new area and we plant them,” Landscape Solutions said.
The project used Arborgreen’s timber stakes. The sawn pointed Australian hardwood stakes are used for a wide range of tree planting applications, from seedlings requiring longer lasting stakes to mature tree planting in roadside and urban applications.
“We’ve used Arborgreen before. We picked Arborgreen for this project because of their competitive price and because they’re a local distributor. It’s good quality products for a good price,” the spokesperson said.
The RMS website said the Newcastle Inner City Bypass between the Pacific Highway at Windale and the Pacific Highway at Sandgate will “provide an orbital road linking Newcastle’s radial network”.
“The bypass is being planned and constructed in five major sections. Sections completed to date are the West Charlestown Bypass, Kotara Heights to Rankin Park and Jesmond to Shortland. The two remaining sections are Ranking Park to Jesmond and Shortland to Sandgate.”
In an article by ABC, it said that the NSW government will commit nearly $300 million in the budget to fund the final link for the bypass.
In January this year, the 1.8 kilometres Shortland to Sandgate bypass opened for traffic use. It contained hundreds of plants that Landscape Solutions planted.
An article by Belinda Jane Davis from the Newcastle Herald said “five specifically-designed bridges were built to combat the soft soil in the surrounding wetlands and limit the intrusion on the environment”.
As it was a straightforward project, Landscape Solutions said they had no complications with the whole process. “The only minor issue is just going over the maintenance, but that’s not anything to worry about,” the spokesperson said.
Landscape Solutions planted around 120,000 native grasses and 20,000 shrubs and trees. “It was a very large scale basic sort of work. We will definitely use Arborgreen products in the future,” the spokesperson said.
Corflute guards protect Anembo Park trees
Arborgreen’s Corflute tree guards are now protecting new trees at Anembo Park in Mount Barker, South Australia. The Anembo Park planting is part of a larger project funded by the Australian government to improve the catchments of the Rodwell and Mount Barker Creeks.
Sherie Bain is the Eastern Hills and Plains Project Officer for the Goolwa to Wellington Local Action Planning Association Inc (GWLAP). Sherie managed and coordinated the project as part of her role with the GWLAP – a community based environmental organisation. The project was run together with the District Council of Mount Barker.
“We are working on 35 other sites as part of the same project and works include revegetation, pest animal and weed control and remnant vegetation enhancement,” Sherie said.
Anembo Park is over 29 acres and is located between Mount Barker and Littlehampton on Adelaide Road. It has a softball diamond, two soccer ovals, a hockey pitch, six tennis courts, BMX track, remote control car track, playground with BBQ and seating area, public toilets and a clubhouse with canteen and bar facilities. The site was chosen because of its location – high visibility, easy access and existing red gum overstorey in the creek line. “The high profile nature of the site has made it the focal point of the Rodwell and Mount Barker Creek project. Hundreds of people use the sporting facilities each week and will watch the restoration of waterway as it evolves over time,” Sherie said.
Site preparation started in July 2013, removing the woody weed species from the area. Planting started in June 2014, and was conducted by 65 members of the local soccer club who use the Anembo Park facilities. “Approximately $20,000 has been spent on the project covering the weed control, site preparation, plants and so on,” she said. Sherie added that the durability of the guards made them the most appropriate to use for this site. Corflute tree guards are made from rigid plastic, excellent for protecting young trees from wind damage or foraging animals. They are very durable, very easy to install and remain presentable much longer than other forms of tree guard. Unlike previous models, these guards are welded at one seam and folded at the others. “It is hoped the guards will stay in place and protect the new seedlings in the event of minor flooding and protect them from stray balls and children,” she said.
There are 3,000 seedlings on the site. A mixture of 16 local native species for riparian environments were used, including sedges, rushes, grasses, shrubs, and trees. “The GWLAP aims to support local businesses wherever possible and have a great relationship with the local Arborgreen store in Mount Barker. The GWLAP purchases approximately 50,000 tree guards from Arborgreen annually.”
Sherie said they were not able to use Corflute guards on all the sedges that were planted “as the creek level was predicted to rise soon after the completion of the planting”. Instead, the sedges were all marked with stakes and the remaining guards were used at a council wetland 500 metres downstream.
A month after the planting was finished Sherie said everything is looking great. “The guards have stood up to some wild weather and are doing their job.”
SA Goyder Reserve gets the Arborgreen treatment
Goyder Reserve in Mylor, South Australia has been revegetated with the help of Arborgreen products.
The project involved willows being removed over several years from Goyder and Cooper Reserves, spanning opposite banks of the same watercourse near the township of Mylor in the Adelaide hills. Stephen Anderson from Environmental Regeneration Australia (E.R.A.) said they were engaged by the District Officer for Natural Resources, Adelaide and Mount Lofty Ranges to assist with weed control and additional planting of local native seedlings. This was the first year of planting on Cooper Reserve with efforts having been focused on Goyder in previous years.
“The Natural Resource Management Board (NRM) assisted the Mt Barker Council and this year the Adelaide Hills Council to undertake exotic species removal and re-vegetation. The aim is to restore native species to stabilise the creek banks and bed as well as improve biodiversity, aesthetics and amenity for park users,” Anderson said. E.R.A. has been involved in the management of the site for two years with approximately $5000 spent on maintenance and re-vegetation after willow removal. E.R.A. used Arborgreen’s welded coreflute guards with a heavy, flat profile hardwood stake.
“We find this product from Arborgreen is consistently of high quality with little breakage or UV degradation and it can be reused multiple times if desired. We understand it is also recyclable.The punched slots in the guard prevent it from splitting where the stake is inserted and the hardwood stake can be driven into difficult ground with greater force. The flat stake is particularly important as it prevents the guard from spinning in the wind and damaging the seedling,” he said.
A range of native plant species has been planted on the site with a particular focus on planting sedges, rushes and watercourse-adapted shrubs (such as tea tree and bottlebrush) with soil-binding root systems along the toe of the bank. Trees and shrubs, such as eucalypts and wattles, have been planted on the upper bank, around 5,000 stems in total of all species having been planted over three years. Arborgreen at Mt Barker have supplied E.R.A. with various products for several years now.
“They are able to source the right products and equipment for our needs and act on our feedback. The service is always prompt and friendly. Like E.R.A, Arborgreen is Adelaide Hills based. This means most jobs involve travel across a broad region. Flexibility with delivery and minimal additional cost is crucial to E.R.A. being able to offer the best price and service to its own customers,” Anderson said. He added that they encountered some difficulties at the site as it is “highly prone to bank erosion”.
“Our efforts are aimed at planting fast growing plants with networks of fine roots immediately after weeds are removed to restabilise the banks. Some woody and creeping weeds, which once formed the exotic understory, are still present and require further attention whilst the new plants establish on the site. So far plantings on Goyder Reserve look like they have established well,” Anderson said.
“The results have been improved for vulnerable species and niches by using tree guards, which have performed well where installed. The absence of the willows has allowed more light into the site and ultimately will aid in the establishment of new vegetation. A healthier watercourse supporting more diverse aquatic life will also lead to better water and a better local environment,” he said.
SurePave: Part of a sustainable home
An environmentally friendly home in Bald Knob has used SurePave to complete its theme.
The total project involved the renovation of an existing home at Bald Knob, halfway between Landsborough and Maleny on the range overlooking the Sunshine Coast, north of Brisbane, Queensland. The home, which was originally constructed in 1986, has a high degree of automation such as lighting, security, floor heating and more. It has an open plan design with extensive verandas using eco glass and modern finishes.
It also has water conservation facilities such as the 85,000 litres rainwater storage and an advanced secondary wastewater treatment plant (treated water suitable for irrigation). n order to continue the sustainability theme of the project, “the traditional concrete or asphalt driveway was discarded in favour of a gravel driveway”.
Frank van Schagen and his wife Sandra are the owners, project managers and constructors of the driveway. With our architect, Mick Hellen of Aardvarc Architects West End Brisbane, we designed the renovation and extensions to the existing home that would make it a 21st century dwelling,” Frank said.
“However, with the slopes on the site, gravel would be unstable if not restrained laterally, hence various options were researched. From our research, SurePave was identified as potentially providing a good solution,” he added.
Frank said he contacted Arborgreen early in 2013 and discussed SurePave as well as seeking references for other sites where the product has been used before. Arborgreen also provided a sample of the product in the early stage of discussions.
“Although neither site had used gravel fill but instead used decomposed granite or soil/grass, we were impressed with the product’s performance and look,” Frank said.
The home was constructed by Ross Sinclair Constructions from November 2012 to November 2013. In late May this year, “the compacted road base driveway area laid in January was trimmed to ensure proper drainage”.
“Geofabric was laid over the road base to prevent fine material migrating upwards into the gravel layer. A screededsand layer was laid over the geofabric to remove any undulations in the road base and provide a flat surface on which to lay the SurePave,” he said. urePave was laid on the sand base and 10mm-20mm Mary River gravel was placed into the SurePave and compacted with a flat plate compactor. “Additional, gravel was placed to cover the SurePave to a depth of approximately 20mm.”
Frank said SurePave was chosen for several reasons – product construction (recycled plastic), product design (four sided clipping system and two panels per square metre), observed performance (reference site inspection), and ease of construction.
SurePave offers an attractive alternative for larger areas to the usually unattractive concrete and asphalt pavements – one that is free-draining, structurally strong, aesthetically appealing, cost effective and environmentally friendly.
SurePave is used by property developers, architects, civil engineers and landscape designers in residential and commercial settings. The proprietary lightweight polypropylene interlocking grid structure is designed to stabilise and support grass and gravel, giving these areas the ability to withstand heavy foot and vehicle traffic.
“Bald Knob is a relatively high rainfall area and we assessed that the high permeability of the SurePave/gravel surface would ensure that water flows from the driveway area would be more easily controlled to the drainage pit and the dispersion area in the garden further down the block,” Frank said.
“The price of the product was comparable to others in the market. However, quality and other criteria was assessed as superior,” he added.
The product installation instructions were followed and no installation problems occurred. Although plants are not part of the driveway, they will be planted in areas alongside the driveway as part of the site landscaping.
At this stage, a planting design using Australian natives has been prepared and will be implemented over the next few months,” he said.
“The driveway looks spectacular, we could not be more pleased with the result. Comments from our neighbours, who were all intrigued by what we were doing, have also been most complimentary regarding our innovative solution to our driveway surface,” Frank said.
Successful new development in Maitland
Arborgreen’s reliability has made it the company of choice for the Waterford County Billabong Park project in the City of Maitland, New South Wales. The project is a series of four water quality control basins and turfed surrounds, which included two stages of the residential subdivision. Civil construction began in late 2013 with the landscaping commencing only February this year. The project finished in April 2014.
Joel Barry from Landscape Group said the project consisted of 8,000m2 of mulching, 6,000m2 of jute matting and the planting and establishment of over 100,000 plants.
The project used Arborgreen’s jute matting and pins. The Eko Mat Jute is a very effective means of establishing vegetation quickly and stabilising slopes. “Over the past five years, we have used Arborgreen's rootstop in all street tree plantings at Waterford County. We chose to use Aborgreen due to locality, reliability and competitive pricing,” Barry said.
Although there were no “real issues” during the project, Barry said the summer conditions made establishment difficult “as the basins were empty and water trucks were used”. “However, the season broke and conditions became more favourable. An earthen bund and dish drain was constructed to prevent scouring of mulched embankments of basin walls,” Barry said.
As of today, the “above average autumn rainfall has made establishment relatively simple with minimal plant loss and vigorous plant growth”. He said that regular maintenance has kept the weeds under control and that there have been no major issues since the project finished.
Around 100,000 tubestocks were planted with species including Lomandra Hystrix, Lomandra Longifolia, Carex Appressa, Ficinia Nodosa, Juncus Usitatus, Schoenoplectus Validus, Baumea Aurticulata and Eleocharis.
Several hundred trees were also planted with species including Casuarina Cunninghamiana, Melaleuca Styphelioides, Ficus Rubiginosa, Eucalyptus Microcorys, Corymbia Maculata and Corymbia Citriodora.
