Applicants Response:

Background

MCU21/0083 conditions of approval required 1100L shared bins collected by rear loading waste truck along with an Operational Waste Management Plan.

Clarification was sought from the relevant Planning Officer regarding waste collection for the site. It was raised by the applicant that the site would not be suitable for rear or front in access by waste trucks without significant changes required to the development layout. If Council had wanted  on site waste collection this should have been made part of an information request prior to the issuing of a development approval. The plans approved by Council indicated each unit as having their own waste bins within the individual lots.

An alternative proposal was suggested by the Planning Officer to meet the required 1100L of waste storage capacity, without diminishing street amenity with excessive bins. It was proposed that smaller shared bins (360L & 240L bins) within a communal bin enclosure serviced weekly with possibility to increase service if needed, would satisfy the condition of approval.

This alternative was raised with the Waste Team who were supportive of shared bins in the format of 4 x 360L (equating to 1440L) and 5 x 240L (1,200L) over the required waste storage specified in the conditions of approval.

The bins are proposed to be collected kerbside with weekly collection for general waste 4 x 360L bins sited kerbside and fortnightly 4 x 360L & 5 x240L (9 bins) which is considerably less than the development up the road at 31 Toolar Street, currently having 6x 240L general and 6 x 240L recycling maxing the fortnightly collection at 12 bins.

Waste Collection Schedule:

Toolar Street, Tewantin

Week One
Monday	Tuesday	Wednesday	Thursday	Friday	Saturday	Sunday
	4 x 360L General Waste					
Week Two
Monday	Tuesday	Wednesday	Thursday	Friday	Saturday	Sunday
	4 x 360L General Waste 5 x 240L Recycling					

Extract from email with Planning Officer:

4.1 No Refuse truck required on site therefore load limits not required.

4.2 Location and bin numbers are detailed on RSA BA 8010-B and BA 2010B.

4.3 Domestic general waste and recycling is considered sufficient for the complex as outlined above which meet the minimum service levels. Green Waste Bins are not required.

4.4 Not proposing to have truck on property for waste service.

Response:

5.1 Revised Landscaping Plan (issued 10.01.2023) showing location of services and infrastructure including service pits, bins enclosure etc.

Refer attached revised landscape Plans (Attachment 4).

5.2 Electrical Engineer has prepared preliminary design plans. No requirement for onsite electrical transformer.

Refer attached preliminary electrical plans (Attachment 6)

5.3 There is no requirement for a fire pump. The site has hydrant cover from an existing street hydrant & brigade appliance in accordance with the state planning policy.

Please refer to Attachment 7. HCT Group – Flow and Pressure Test Report demonstrating compliant street hydrant flows are achieved.

Provide a Consolidated Services Plan to demonstrate how the applicable Performance
Outcomes can be achieved. This may include:

5.1. asingle overlayed plan to show areas of deep planting exclusive of services where
trees are capable of being planted and allowed to grow to full form without
management input (heavy pruning, removal, interference with infrastructure

5.2. the location of the Pad Mount Transformer
5.3. the location of the fire fighting booster pump

Response:
Backflow prevention measures are included on the hydraulics consultant's documentation. These

requirements should be approved through the building application process, not operational works.

‘We have nominated gross pollutant trap insert (GP) filters on the grated stormwater pits across the site
‘on our revised stormwater drainage plan attached.


[Attachment: image3.png (image text)]
Provide amended plans and supporting calculations which fully address Condition 30 of
MCU21/0083. If the applicant does not have the capability to undertake modelling, then
a deemed-to-comply approach such as that nominated in Section 4.3 of the Flooding
and Stormwater Management Guidelines (SCC, 2020) may be an acceptable
alternative. Include calculations for the maximum water level in the detention tank and
demonstrate that freeboards are met.

Res:
‘We have included results from our drains analysis for the detention/re-use water tanks sizing on our
revised stormwater drainage plan attached. The analysis has used ensemble temporal patterns sourced
from the Bureau of Meteorology.

3. Some of the nominated Unit FFLs have minimal elevation above the driveway levels and
resulting surface stormwater flows. Consider improving the resilience of the units to local
flooding by providing a step-up into the units from the carport and garage areas.


[Attachment: image8.png (image text)]
 

Provide the required Operational Waste Management Plan that demonstrates
compliance with the conditions. The plan must include but not be limited to:

4.1. Load rating on the underground tanks. Please note that refuse collection trucks
weigh 23.5T

4.2. The location and number of 1100 litre bins
4.3. The expected service levels (Refuse, Recycle and Garden)

4.4. Clarification if the pedestrian shared zone has an awning and suitable horizontal
and vertical clearances are available for the whole length of the refuse collection
truck route within the site

Subject: RE: MCU21/0083 - Clarification Condition 42 & 43
To: Hayley Jamieson <[email protected]>

Hi Hayley,

With regards to the condition requiring a waste management plan:

The policy details the types of developments which must have an Operational Waste Management Plan (OWMP) - this does not mean that developments which do not meet the threshold
can't be required to provide an OWMP.

have sought comment from the waste team with regards to the method of collection from this site and been advised that 10 units would normally have a shared service using 1100ltr bins
to save from having to have a bin area large enough to accommodate 20 x 240It refuse and recycling bins. A shared 1100ltr bin is clearly better than having 20 bins along the street frontage
on service nights. A shared bin or bins can be serviced multiple times per week to achieve the waste collection volume required.

 

The requirement to have a bin wash fa the bin area is to enable the Body Corp to clean bins appropriately and not have 20 bins being washed out in on a small patch of lawn or
the storm water system as the dwellings are not located on suburban blocks of land which can place their bins at the rear of the residence.

   

IFitis not possible to have a service vehicle access the site in a forward direction, which appears to be the case from the plans, then a comparable solution is required. For example, a
central bin area with shared 240It or 360It bins that can be taken to the street for service and returned to the bin area, maybe a service regime like twice weekly.

| hope this clarifies your query — happy to discuss further.
Regards

Patrick
