site details
Background
The subject application follows on compliance action after a complaint was received regarding earthworks (dam) on the subject property.
A site inspection was undertaken on 02/07/2020 and an email was sent, to the owner of the subject property, outlining the requirements for the dam works being self-assessable.
Initially, the information provided by the applicant indicated that the dam works were self-assessable, but the scope of works increased (i.e. internal access driveway, crossing a mapped waterway, to access a new shed), hence triggering the requirement for an operational works application (earthworks).
The works being assessed (earthworks) created the necessity of a secondary driveway, which Council is willing to accept as part of the subject approval.

Pavement design for privately owned works must be undertaken in accordance with the relevant standards.  Structural integrity of the driveway and car park areas will remain the responsibility of the property owner/developer and must be certified by an RPEQ.
Works within Road Reserve/Reinstatement
Safe pedestrian access on all streets in the vicinity of the development must be maintained at all times. Should footpath/road closures be necessary to carry out construction works, Council’s Engineering Officer must be notified prior to the proposed closure and all requirements complied with.
All frontage works must match neatly with existing road and verge/footpath features. Additional works beyond the frontage may be required to provide an acceptable transition to existing road and verge/footpath profiles.
Electrical conduits or other services proposed to be installed within existing and proposed road reserves under existing sealed carriageways, concrete pathways, concrete/sealed driveways or significant vegetation must be installed by boring. Trenching is not permitted, unless specifically approved by Council.
Site Access and Driveways
Driveway crossover must be constructed in accordance with council’s Standard Drawing RS-56.
Any existing unnecessary or redundant property accesses must be removed, and the kerb, footpath and verge area reinstated to match the existing footpath and/or verge treatments. Grassed verge areas to be reinstated must be provided with 100 mm topsoil and grass seed or turf, and must be maintained by the developer until established.
The following must be complied with during the construction of the required crossover/driveway:
The driveway must have 1.5 metres (minimum) of flexible pavement abutting into the existing road edge;
The driveway surfacing must consist of either an approved hot mixed asphaltic concrete or patterned/plain concrete;
The driveway must be in accordance with the requirements of AS2890.1 Off-Street Car Parking for longitudinal and crossfall gradients;
The driveway must be constructed so as not to concentrate or direct stormwater runoff onto neighbouring properties;
Where there is an existing pedestrian path, a matching crossfall must be provided for the driveway on the alignment of the path, for the full width of the path;
The property access must be located a minimum of 1m clear of existing power poles, streetlights or other signage. The developer is responsible for any necessary relocation of existing services to provide this clearance and must contact the relevant service authorities and comply with their requirements in relation to these works.
Earthworks and Retaining Walls
All earthworks must be undertaken in accordance with the provisions of AS 3798 Guidelines on Earthworks for Commercial and Residential Development, with geotechnical testing undertaken in accordance with Section 8 of the Standard, and to a minimum of ‘Level 2’ as defined in Appendix B. Test results as required by AS 3798, and a certificate of quality and uniformity of fill must be provided by a RPEQ and submitted to Council prior to the final inspection.
Fall protection must be provided to retaining walls that are over 1m high.
Slope and batters are a maximum grade of:
1 in 6 where in proximity to waterbodies;
1 in 4 for grassed areas;
1 in 3 for planted areas;
1 in 2 for combined structural engineering and planting solutions.
Stormwater Drainage
Appropriate scour protection must be provided at the outlet of all stormwater pipes including temporary outlets.
Works associated with this permit must not adversely impact on the existing drainage conditions on other properties (e.g. by blocking or interfering with natural overland flows).
Construction of all internal stormwater drainage works must comply with the relevant section/s of Australian Standard AS/NZS 3500.3.
Erosion and Sediment Control
Prescribed Water Contaminants (as defined in Schedule 10 of Environmental Protection Regulation 2019) must not be released from the site or to waters within the site, or be likely to be released should rainfall occur, unless all reasonable and practicable measures are taken to prevent or minimise the release and concentration of contamination.
Sediment and erosion control measures must be in place prior to works commencing. If such measures are not in place or are not satisfactory, “on the spot” fines may be issued. Such fines can be issued if sediments from the site are found to enter or have the potential to enter Council’s stormwater system, natural waterways, any downstream stormwater filtration system or adversely impacting on other properties.  The sediment and erosion control design and measures have NOT been approved, it is the site's Supervising Engineer who is responsible for ensuring that the sediment and erosion control measures have:
Been duly designed by an RPEQ or CPESC and constructed in accordance with "best practise" methods;
Been revised by an RPEQ or CPESC to address the issues raised by changes in the projected construction schedule and/or methods;
Been revised to address predicted rainfall events; and
Achieve the desired environmental outcomes.
Council may request further controls to be installed should the implemented measures be found inefficient.
The erosion and sediment control measures must be designed, installed and maintained in accordance with the supervising engineer instructions and the current best practice standards * (Refer to Advisory Note).
The developer must ensure non-essential exposure of soil is prevented by restricting the extent of disturbance and minimising the duration of soil exposure to adverse weather conditions and effectively turf, cover or stabilise any disturbed area without delay and prior to rainfall occurring.
The developer must ensure sediment does not leave the site or enter onto adjoining properties or Council’s drainage system due to surface runoff or on tyres of vehicles and/or machinery. It is essential to implement appropriate approved erosion and sediment control measures throughout the site during all phases of construction including vehicle shakedown pad/grid (or similar) at the access to the construction site. Where sediments or other contaminants are deposited on a road, they must be removed so as not to enter Council’s drainage system or waterways.
Prior to the completion of the development and commencement of use, all site surfaces must be effectively stabilised using methods which have achieved effective short-term stabilisation and which will continue to achieve effective stabilisation in the medium to long-term. For the purpose of this condition, an effectively stabilised surface is defined as one that does not, or is not likely to result in visible evidence of soil loss caused by sheet, rill or gully erosion or lead to sedimentation, or lead to water contamination.
Damage to Services and Assets
Any damage caused to existing services and assets as a result of the development works must be repaired at no cost to the asset owner at the following times:
where the damage would cause a hazard to pedestrian or vehicle safety, immediately; or
where otherwise, upon completion of the works associated with the development.
Any repair work which proposes to alter the alignment or level of existing services and assets must first be referred to the relevant service authority for approval.
FOLLOWING CONSTRUCTION
Certification
Upon completion of the work a certificate must be issued by an RPEQ certifying that the works have been constructed in accordance with the Operational Works permit.
A final inspection and approval of the works and completed reinstatement works by Council’s Inspector is required. Please contact Council on 5329 6500 to arrange for the inspection.

Advisory notes
The following notes are included for guidance and information purposes only and do not form part of the assessment manager conditions:
General Advisory Notes
Council has undertaken an audit check of the Operational Works drawings in relations to the proposed works.  A detailed check of the calculations and drawings has not been undertaken, as they have been certified by a RPEQ. The RPEQ bears full responsibility for all aspects of the engineering design.  Council reserves the right to require further amendments and/or additions at a later date should design errors become apparent.
Council reserves the right to call up any performance bond held or levy charges against the property, should emergency works be required to be undertaken by Council to make the site safe due to inactivity on the development site for extended periods of time.
Should any changes or modifications to the approved plans be required as a result of construction constraints, a “Request to change an existing approval” under the Planning Act 2016 must be made. Amended plans clearly indicating the changes must be lodged with this application along with the appropriate fees.
Prestart and Inspections Request
Contact Council on 5329 6500 to arrange a prestart or an inspection giving a minimum of 5 business days’ notice of preferred inspection time.
If Council officers are required to undertake additional inspections of the same works, a reinspection fee will be applicable in accordance with Council’s Fees and Charges register applicable at the time.
A minimum maintenance period of 12 months will apply to all municipal works and thereafter until such time as the works are performing in accordance with the approved design unless noted otherwise
Environmental Advisory Notes
The Environmental Protection Act 1994 states that a person must not carry out any activity that causes, or is likely to cause, environmental harm unless the person takes all reasonable and practicable measures to prevent or minimise the harm. Environmental harm includes environmental nuisance. In this regard persons and entities, involved in the civil, earthworks, construction and landscaping phases of this development are to adhere to their ‘general environmental duty’ to minimise the risk of causing environmental harm.
Erosion and Sediment Control
Accepted best practice standards include International Erosion Control Association Australasia Best Practice Erosion and Sediment Control
Qualified Person, for the purpose of erosion and sediment control is a Certified Professional in Erosion and Sediment Control (CPESC) or suitably experienced Registered Professional Engineer of Queensland (RPEQ).
As a general rule, a site is determined to have achieved effective short-term stabilisation if at the time of the final inspection:
Methods of stabilisation are:
appropriate for slopes and slope lengths; and
are consistent with best practice environmental management practices such as in the Manual for Erosion and Sediment Control or the IECA Manual; and
Stormwater runoff from the site is not currently, and is not likely to result in visible evidence of sedimentation or erosion, or lead to water contamination.
If at the time of request for the final inspection, the method of short-term stabilisation has not achieved a level of stability that Council's Officers believe will have a high probability of achieving long term stability (i.e. until house construction has occurred on all lots), Council Officers may take the following matters into consideration in determining whether the site is capable of achieving medium to long-term stability:
evidence that the site has been effectively stabilised in the short term;
evidence that soil has been adequately ameliorated;
evidence that seed of annual and perennial grass species has been applied at an adequate rate; and
that grass seed has germinated at a density that is likely to achieve an effective grass cover.
