Introduction

 

The owners of both 24 and 26 Gale Road, Maroubra, have written to Council advising of a range of ongoing and increasing damage to their properties and adjacent public infrastructure being caused by the large roots of a mature Council owned Ficus ‘Hillii’ (Hill’s Weeping fig) street tree growing on the nature strip outside their properties.

 

Issues

 

Initially, on 20 November 2012, the owners of 24 Gale Road, Maroubra, emailed Council advising that they were concerned about large fig tree branches overhanging their residence posing a threat to their safety during high winds and storm events. 

 

Subject to receipt of this correspondence I inspected the subject tree but could find no visual evidence to justify the removal of such a large and healthy street tree asset. I did, however, arrange for the tree to be extensively pruned to negate some of the concerns relating to property overhang.

 

The property owners were subsequently advised that Council would not accede to their request for this tree to be removed and that any such request would have to be supported by compelling evidence of significant and ongoing damage being caused by such a tree.

 

The owners of both 24 and 26 Gale Road, Maroubra, then wrote to Council in early January 2013 and collectively nominated a range of damage being caused by the subject fig tree, including regular sewer blockages, expensive sewer pipe replacement, structural damage to front gate pillars, raised internal pavers, ongoing and increasing damage to the Council footpath and driveway crossover and proximity of tree roots to internal services such as gas and water. Both property owners emphasised they appreciated the visual significance of the tree but expressed they had major concerns about its long term retention.

 

The subject tree is approximately eighteen metres in height with a canopy spread of between sixteen-eighteen metres. It is in good health and contributes significantly to the Gale Road streetscape. It is also an important provider of habitat and food source for a variety of native birdlife and other fauna.

 

Over the past decade the adjacent footpath has had to be repaired on a number of occasions because of tree root damage but roots continue to enter both properties as well as cause ongoing damage to public infrastructure. On 8 February 2013 Council’s Tree Gang trenched along the front property boundaries and this revealed masses of tree roots have completely undermined the surrounding footpath area, driveway and adjacent internal driveway.

 

Council’s Tree Gang arborists advise that it would not be possible to remove the amount of damaging tree root material required to abate the damage being caused by the roots of this large street tree without seriously compromising its stability and long-term viability. The subject tree also has to be regularly pruned out of overhead powerlines and well clear of adjacent service wires.

 

Relationship to City Plan

 

The relationship with the City Plan is as follows:

 

Outcome 10:     A Healthy Environment.

Direction 10b:    Environmental risks and impacts are strategically managed.

Key Action:       Develop and implement policies, programs and strategies to manage environmental risks and impacts.

 

Financial impact statement

 

It is estimated that the removal of the Hill’s Weeping fig outside 24-26 Gale Road, Maroubra, and its replacement with one-two super-advanced Waterhousia floribunda (Weeping Lilly Pillys) would cost in the vicinity of $4,000. The required funds would come from Council’s annual tree management budget.

 

Conclusion

 

The Council owned Ficus ‘Hillii’ street tree growing outside 24-26 Gale Road, Maroubra, is in very good health and contributes in a very positive way to the surrounding streetscape.

 

It is estimated that the tree is approximately sixty years old and up until now Council has been committed to retaining it, despite the fact that associated tree root damage has progressively increased in both frequency and severity.

 

The tree has been assessed as having significant scenic and amenity value and with providing important habitat and food source for a variety of fauna. Because of the damage being caused by its roots, the impact of removal on land degradation would be negligible. Using Australian Standard ASDR99307 the tree has been calculated to have an amenity value of $21,600.

 

It has also been calculated that the tree has a moderate hazard rating but this will increase if the tree is retained and the impact of regular root pruning begins to take its toll. However, because of the size and amount of root material required to be removed from the tree to effectively deal with the damage being caused by its roots, root pruning is regrettably not in any way a viable option. This is supported by the findings and recommendation made by Council’s Tree Gang when a trench was dug adjacent to where the tree is located. Effectively, therefore, the only practicable long-term management option is to remove the subject Ficus ‘Hillii’ and to replace it with a more appropriate tree species – as nominated in Council’s Street Tree Masterplan.

 

The removal of this tree will have a detrimental impact on the Gale Road streetscape that will in no way be able to be mitigated in the short term by the planting of advanced replacement trees. However, Weeping Lilly Pillys are a fast growing species that will attain a sizable dimension at maturity and they would replicate to some degree the overall shape of this fig tree should it be removed.

 

 

Recommendation

 

That the large Council owned Ficus ‘Hillii’ (Hill’s Weeping fig) growing outside 24-26 Gale Road, Maroubra, be removed and replaced with one-two Waterhousia floribunda (Weeping Lilly Pillys) – as nominated in Council’s Street Tree Masterplan.

Subject:                  Tree Removal - Outside 113-117 Gale road, Maroubra

Folder No:                   F2004/07359

Author:                   Bryan Bourke, Tree Management Officer     

 

Introduction

 

The owners of 117 Gale Road, Maroubra, wrote to Council on 23 November 2012 advising of a range of ongoing and increasing structural damage to several properties and adjacent public infrastructure being caused by the large roots of two mature Council owned Ficus ‘Hillii’ (Hill’s Weeping figs) street trees growing on the nature strip outside 113-117 Gale Road, Maroubra. This correspondence was accompanied by a petition signed by ten surrounding property owners requesting that the two subject trees be removed and replaced with more appropriate species.

 

Subsequent to the receipt of this correspondence, the owners of 115 Gale Road, Maroubra, wrote to Council on 4 December 2012 also advising of a range of problems associated with these two street trees and requesting their removal.

 

Issues

 

These two property owners have detailed a range of damage being caused by the roots of the subject fig trees, including cracking and undermining of their front fences, ongoing and increasing damage to Council infrastructure (footpaths and driveways) and tree root damage being caused inside the actual properties.

 

The two trees average eighteen-twenty metres in height with canopy spreads of around eighteen metres. They are both in good health and contribute significantly to the Gale Road streetscape. They are also important providers of habitat and food source for a variety of native birdlife and other fauna.

 

Over the past decade the adjacent footpath has had to be repaired because of tree root damage but roots continue cause ongoing and increasing damage to public infrastructure. Roots from both trees form a huge mass that has completely undermined the surrounding footpath area, driveways and adjacent front fences. Council recently trenched along the front of 113-117 Gale Road and this revealed a number of large fig tree roots entering all three properties.

 

Council’s Tree Gang advises that it would not be possible to remove the amount of damaging tree root material required to abate the damage being caused by the roots of these trees without seriously compromising their stability and long-term viability. If any root pruning were to take place there is every likelihood that one or both trees would topple onto Gale Road and bring down adjacent overhead powerlines and service wires as well as damaging a range of underground services. Both trees have had to be regularly pruned away from those overhead powerlines and domestic service wires to maintain statutory clearances and branches have to be regularly pruned back from overhanging the residences.

 

Property owners have identified fig tree roots growing within the front of their properties and one property owner is convinced that cracks in the wall at the front of his residence have been caused by fig tree roots. That same property owner had to postpone internal driveway works until Council’s Tree Gang had severed enough fig tree material to allow those works to continue.

Relationship to City Plan

 

The relationship with the City Plan is as follows:

 

Outcome 10:     A Healthy Environment.

Direction 10b:    Environmental risks and impacts are strategically managed.

Key Action:       Develop and implement policies, programs and strategies to manage environmental risks and impacts.

 

Financial impact statement

 

It is estimated that the removal of the two Hill’s Weeping figs outside 113-117 Gale Road, Maroubra, and their replacement with an appropriate number of advanced Eucalyptus haemastoma (Scribbly gums) would cost in the vicinity of $6,000. The required funds would come from Council’s annual tree management budget.

 

Conclusion

 

The two Council owned Ficus ‘Hillii’ street trees growing outside 113-117 Gale Road, Maroubra, have significant visual and historic significance.

 

These trees are estimated to be approximately sixty years old and up until this point Council has been committed to retaining them, despite the fact that associated tree root damage has progressively increased in both frequency and severity.

 

Both trees have been assessed as having significant scenic and amenity value and with providing important habitat and food source for a variety of fauna. Because of the damage being caused by their roots, the impact of removal of one or both trees on land degradation would be negligible. Using Australian Standard ASDR99307 the trees have been assessed as each having an amenity value of $21,600. It has also been calculated that the trees have a moderate hazard rating but this will increase as the trees age and weather events become more severe. Because of the size and amount of root material required to be removed from both trees to effectively deal with the damage being caused by their roots, root pruning is not in any way a viable option. This is supported by the findings and recommendations made by Council’s Tree Gang arborists when a trench was dug adjacent to where the trees are located.

 

Effectively, therefore, the only practicable long-term management option is to remove the two subject trees and to replace them with a more appropriate tree species – as nominated in Council’s Street Tree Masterplan. The removal of these trees will certainly have a detrimental impact on the Gale Road streetscape that will in no way be able to be mitigated by the planting of advanced replacement trees. However, they are the only two examples of this tree species growing along this section of street and they are quite incongruous compared to other more appropriately sized species.

 

 

Recommendation

 

That the two Council owned Ficus ‘Hillii’ (Hill’s Weeping figs) growing outside 113-117 Gale Road, Maroubra, be removed and replaced with an appropriate number of Eucalyptus haemastoma (Scribbly gums) – as nominated in Council’s Street Tree Masterplan.

Subject:                  Cleaning Service Provision for Australian Turf Club

Folder No:                   F2004/07286

Introduction

 

Council has been approached to provide cleaning services for special events at Randwick racecourse.

 

Issues

 

The venue will be utilised for an all-day event from 10.00am on 9 March 2013. The site is required for a second event commencing at 1.00pm 10 March 2013.  The area required to be cleaned will be the infield that is accessed via High Street and the vehicle tunnel that has a 3.4m height restriction. 

 

During the event it is virtually impossible for the waste to be collected due to crowd movements and hence that presents a big problem with crushed cans and bottles and especially water bottle tops that all get to be trampled in to the ground over the duration of the event.

 

The infield paddock will be set up as a music festival with a number of stages, stalls, seating decks and elevated viewing platforms but typically the areas is 30,000m2.  The waste will be predominantly PET bottles and cans, with the potential for a small amount of paper and food waste.


We have proposed:

 

1.   The services of three street sweeping vehicles and operators

2.   The three units to be onsite ready to commence operation from 11.30PM on Saturday 9 March 2013 working continuously until 3.30AM collecting as much volume as possible.

3.   The organisers will provide an  onsite empty station (location TBC) consisting of a number of 10m3 skip bins with a load height of less than 1100mm for the units to empty in to.  This would save the units from emptying at a transfer station offsite.

 

Relationship to City Plan

 

The relationship with the City Plan is as follows:

 

Outcome 6:       A Liveable City.

Direction 6b:      Our town Centres, beaches, public places and streets are safe, inviting, clean and support a recognisable image of our City.

 

Financial impact statement

 

Council Officers have negotiated a rate of $200 per hour per vehicle with a minimum of four (4) hours.

 


Conclusion

 

This provides an opportunity for Council staff to provide a service ordinarily provided by a private contractor.

 

 

Recommendation

 

That the report be received and noted.
