Extract from the Citys Aerial Photography (source Landgate February 2016):

With reference to the above two extracts from the Citys Scheme and aerial photography, the context of the site and local area is described below: 1. The subject land is located with the Canning Vale Industrial Estate, which is

characterised by industrial development including distribution warehouses, workshops and showrooms, and situated approximately 13km south-east of the Perth Central Business District and 4km north-east of Jandakot Airport;

2. The subject Lot 1003 was created in 2015 as part of the subdivision of the former Swan Brewery Estate. Lot 1003 is vacant and was cleared of structures and vegetation as part of subdivision works; and

3. Roe Highway is located to the north and a freight rail line is located to the south, which generally delineates the industrial precinct and provides separation to the adjoining residential areas.

Details: With reference to the attached development plans and Applicants supporting planning report dated 12 April 2016 (refer to Attachments 2 and 3), the key aspects of the proposed development includes the construction of the following buildings and structures: 1. 22,243m warehouse with 7,556m external adjoining breeze ways.

The warehouse will be used for the storage and distribution of alcoholic beverages. The warehouse will consist of loading, unloading, dispatch and storage areas, with the main storage area containing floor to ceiling racking used for the storage of beer, cider and wine. Spirits will have their own isolated racking area. Loading and unloading docks are located on the east and west sides of the buildings. Access to the docks will be provided via the internal vehicular thoroughfare (breezeway) which is for the exclusive use of trucks and service vehicles. The thoroughfare wraps around the warehouse and facilitates one-way vehicle movement, which allows trucks to enter and exit the site in a forward gear. Access to the docks will be provided through a manoeuvring area within the site, which will support all required vehicle movements, as well as provide for vehicle parking. The warehouse will be primarily constructed with Colorbond steel in surfmist and cortex finishes. The applicant has advised that the warehouse will employ approximately 120 staff members and operate on a 24 hours a day, 6 days a week basis. The operational hours will increase to 7 days a week during peak periods. The staff members will work varying shifts with approximately 60 staff members on site at any given time and 110 staff members on site during peak times and changeover periods.

2. 700m Battery Charge building adjoining the front of the warehouse. This building is used to charge batteries for the forklifts used on site. Its been provided as a separate room to comply with the ventilation requirements for battery charging areas.

3. 1,248m office and amenities floor space and a 156m of outdoor area for use by staff. Three separate offices areas totaling 1,248m (including staff amenities) are proposed. The offices will provide for the administration activities associated with the direct operations of the distribution warehouse. The primary office building is located at the south side of the warehouse fronting Brewer Road. This office aims to act as the front door for the development. The other office areas are dock offices which are located slightly north of the main office on the eastern and western edges of the warehouse. The eastern office consists of a two storey building, while the western dock office will be a single storey office

building. These offices provide an administrative area to facilitate deliveries, dispatch and logistics for the warehouse.

4. 155 line-marked car bays and space for a further 358 reserved car bays. The 155 line-marked car bays for the use of staff and customers will be located within the front setback area. There are also two reserved/deferred parking areas where an further 358 car bays, required under Table 6 of the Citys Scheme, may be provided to accommodate parking needs for future redevelopment or a change of business operations. One of the deferred car parking areas will be paved as part of this application whilst the other will be landscaped. Further commentary on the provision of parking is provided in the Planning Assessment section.

5. Four (4) access points for vehicles.

A Transport Assessment by Cardno dated 7 April 2016 has been submitted by the applicant in support of this application (refer to Attachment 5). This report concludes that the proposed development will have no impact on the existing road network. A single crossover is provided for entry and exit into the staff and customer car park. This crossover aims to facilitate full vehicle movements onto Brewer Road. Separate truck access points have been provided on the east and west sides of the Brewer Road frontage. These crossovers allow for one (1) way vehicle movements entering and exiting the site. The truck sweep path will allow a B-Double 26m truck to enter the site from the western Brewer Road crossover, maneuvering around the warehouse and exiting via the eastern Brewer Road crossover.

An additional access point is provided via Barley Place. This crossover allows for full truck movements entering and exiting the site. However, this access point is intended to only be used for emergencies and not as part of the day to day operations of the warehouse. The applicant has advised that all of the truck access points will be controlled via motorised boom gates and/or motorised sliding gates. The boom gate at the sites Brewer Road entry has been strategically setback a sufficient distance to allow for two trucks to queue within the site area; therefore reducing the likelihood of any traffic building up on Brewer Road.

6. Front fencing.

The Brewer Road frontage includes an 1800m high black vinyl coated chain wire mesh fence with 3 rows of barbed wire across the top. The boundary fence comprised of an 1800mm high black vinyl coated chain wire mesh fence with looped razor across the top. Both fences will be of a height of 2100mm if including the barbed wire and razor wire components.

Legislation & policy: Town Planning Scheme No. 40 The application has been assessed in respect to Part VI Industrial Development of the Citys Town Planning Scheme No. 40 (the Citys Scheme). The subject site is zoned General Industry under the City Scheme. Under Table 3A, the proposed Warehouse is a P use, meaning the use is permitted, and the Office is an IP use, meaning the use is only permitted where it is incidental to the predominant permitted

use. A copy of the Citys Scheme is available to download from the Citys website via the following link: http://www.canning.wa.gov.au/P/planning-services-2.html State Government Policies The Western Australian Planning Commissions (WAPC) State Planning Policy 4.1: State Industrial Buffer (SPP4.1) outlines the requirement for buffers to reduce impacts on sensitive uses, such as residential dwellings, major recreational areas, hospitals, schools and other institutional uses involving accommodation. The subject proposed is located approximately 800metres from residential properties to the north/north-east and approximately 1kilometre from residential properties to the south. SPP4.1 does not require a buffer for the proposed distribution warehouse. Copies of the WAPC State Planning Policies are available to download from the WAPCs website via the following link: http://www.planning.wa.gov.au/State-planning-policies.asp Local Policies Local Planning Policy SRS223 Assessment of Subdivision and Development in the Canning Vale Industrial Area in Proximity to the Canning Vale Residential Area (Policy SRS223) Policy SRS223 provides guidelines for subdivision and development within the Canning Vale Industrial Estate, which aim to ensure that the scale and nature of industrial development is compatible with and minimises any potential impact on the Canning Vale residential area. Part 2.0 of the policy encourages a number of preferred uses, including distribution warehouses. It is considered that the development complies with the provisions of the policy. Copies of the Citys local planning policies are available to download from the Citys website via the following link: http://www.canning.wa.gov.au/P/planning-services-2.html Consultation: Public Consultation It is acknowledged that the number of marked parking bays does not meet the requirements of Table 3B of the Scheme. However, the applicant has demonstrated the ability to provide more than required number of bays if possible. Based on this, it is considered that adequate parking will be provided to suit the needs of the business, and the development will not have an adverse impact on the surrounding industrial area. As such, the decision was made not the publically advertise this proposal. This variation is further discussed in the Planning Assessment section. Consultation with other Agencies or Consultants The City referred the development proposal to the Water Corporation and the APA Group (due to the sites proximity to the Parmelia Gas Pipeline), as detailed below: 1. Water Corporation (WC):

A new stormwater drain is proposed to assist with the sites internal drainage. The stormwater drain will run north along the eastern edge of the sites boundary, wrapping around the rear of the site to connect to Barley Place. A four stormwater design plans (DWG No. C01, C02, C03 and C04) are contained in Attachment 4, and a Management and Disposal of Site Stormwater report from DWA dated 20 March 2016 is provided in Attachment 3. The additional stormwater drain will allow 865m of underground storage which will contain a 1 in 1-year storm event and 930m of above ground storage to manage peak flows in the 1 in 100 year ARI storm event.

The underground portion of the stormwater drain runs under the proposed staff car parking area. Clause 7.2.5 of the Water Corporations Guidelines for Designers specifies that building within an easement may be permitted subject to protection of service requirements being met. The proposed stormwater drain has been designed with regard to the sites other services and infrastructure, most specifically Water Corporations existing easement for drainage. Engineering details of the proposed stormwater has been provided along with a correspondence from Water Corporation, which approves the proposed stormwater drainage system. The Officer Recommendation includes a condition and advice note relating to appropriate disposal of stormwater.

2. APA Group (APA):

The APAs closest asset is the Parmelia Gas Pipeline (PGP) which is situated within a 9 metre easement running along the southern side of Bannister Road in Canning Vale inside private property. The proposed development is approximately 430 metres to the north of the PGP. This application is outside the Western Australian Planning Commission, Planning Bulletin 87 notification zone and outside the residential/industrial/commercial setback distances. The APA has requested that they are notified prior to storing highly flammable, explosive, acid or corrosive material. In this respect, an advice note has been included in the Officer Recommendation section.

Planning assessment: The development application has been assessed with regard to relevant provisions contained in the abovementioned legislation and policies. The City is satisfied that the development complies with the relevant planning controls, and subsequently recommends approval subject to conditions. In making a decision on this development application, the local government (or in this instance the Metro Central JDAP) is required to have due regard to the matters listed under clause 67 of the Deemed Provisions. In addition, clause 64 of the Deemed Provisions enables the decision maker to consider variations to requirements and standards of the Citys Scheme. In this instance, the application requires the consideration of a reduced number of line-marked car parking bays. Table 3B of the Citys Scheme requires the provision of 261 car parking bays for the proposed warehouse and office land uses. The application proposes the construction and line marking of 155 car bays within the front setback area between the building and Brewer Road. A Transport Assessment by Cardno dated 7 April 2016 has been submitted by the applicant in support of this application (refer to Attachment 5). This report concludes that notes that during peak operational periods the development is expected to accommodate a maximum of 110 people on site at the peak time of 2pm, generating a maximum demand for 110 car bays to be utilised by employees. This will leave a total of 45 car bays free for the use of customers and visitors to the site, not including the use of reserve bays. The report concludes that the provision of 155 car bays is considered to be sufficient to cater for the projected parking demand. Should an issue arise, however, the use of parking reserve areas is available.

The provision of 155 car bays in lieu of 261 bays for the proposed land uses is supported by the City on the basis that: 1. The development provides an adequate number of car parking bays to cater for

the projected parking demand of the business; 2. Two parking reserve areas are available for any future changes to car parking

needs. In this respect, the Officer Recommendation includes a condition requiring the provision of a parking management strategy. This strategy will provide flexibility for the business to manage their parking needs without having to seek an amendment to the development approval; and

3. Based on reasons 1 and 2 above, the reduced provision of parking will not negatively impact on surrounding industrial businesses.

Conclusion: It is considered that the development proposal meets the relevant planning requirements. The proposal incorporates a building design and landscaping which will provide attractive and efficient development in the area. It is therefore recommended that the development application be approved subject to conditions, as listed in the Officer Recommendation section.

DEVELOPMENT OF LOT 1003 BREWER ROAD, CANNING VALE MANAGEMENT AND DISPOSAL OF SITE STORMWATER

At the request of Mr David Paz of Linc Property, David Wills and Associates have been engaged to investigate options available for the discharge of stormwater from the development of the proposed development of Lot 1003 Brewer Road, Canning Vale whilst minimising the volume of site storage to compensate the flows. This report will be used to gain Statutory Authority approval. 1. BACKGROUND

The former Swan Brewery site, located north of Baile Road, Canning Vale was an area of approximately 40 ha in size. Recently, this land has been redeveloped as an Industrial subdivision by Linc Property Pty Ltd comprising 90+ new lots, which included the largest lot 1003 of 6.41 ha. The Water Corporation is responsible for the Vinnicombe Drive Compensating Basin which exists just to the north east of the site refer to Site Plan below. It is understood that the original design of this Compensating Basin of approximately 8500 m2 in size, accounted for runoff from impervious surfaces on the full Swan Brewery 40 ha site as well as the adjacent Industrial land subdivision bound by Tacoma Circuit, Ernst Clarke and Baile Roads.

Stage 5 of the subdivision development (Lot 1003) was originally proposed to be further split into smaller Industrial lots. The Developer now intends to develop the Lot to establish a single large Industrial site for BevChain Australia Pty Ltd. The stormwater drainage for the overall subdivision development was to collect all of the new Municipal Road reserve impervious surfaces in a series of roadside catchpits and underground drainage pipes. This stormwater has been designed to be conveyed to the Water Corporation Vinnicombe Drive Compensating Basin via a network of underground pipe drains. All lots within the subdivision were required to contain storms of 1 in 100 year events and discharge the storm water generated from the site by infiltration (the subdivision arrangement does not allow for connection of any subdivision lots to the Vinnicombe Drive Compensating Basin) Given the reduction in impervious area from the original Swan Brewery site contributing flows to the Vinnicombe Compensating Basin, Linc Properties wanted to investigate the opportunity for Lot 1003 to discharge an amount of stormwater from impervious surfaces into the Water Corporation system. Any discharge from Lot 1003, will be required to be consistent with Water Sensitive Urban Design (WSUD) principles of the Department of Water and the Water Corporation Main Drain design requirements. 2. MEETING THE DEPARTMENT OF WATER WSUD REQUIREMENTS

In order to meet the Department of Water WSUD requirements, it is understood that the following criteria is applicable for the subject sites to:

Manage stormwater runoff from constructed impervious surfaces generated by the 1 in 1 year ARI storm of 60 minutes duration, at its source consistent with Water Sensitive Urban Design (WSUD) principles.

Contained at Appendix A, is a calculation of the stormwater runoff volume from the subject site to meet the above requirement is 865 m3 of stormwater generated by the 1 in 1 year ARI storm event. It is proposed that this volume of water be stored below ground and infiltrated through native sands to recharge the groundwater table well below the finished ground surface. This underground storage volume is in addition to any storage necessary to avoid impact on the Vinnicombe Drive Compensating Basin and Water Corporation requirements. 3. MEETING THE WATER CORPORATION REQUIREMENTS TO AVOID ANY IMPACT UPON THE

VINNICOMBE DRIVE COMPENSATING BASIN

The Vinnicombe Drive Compensating Basin forms part of the Bannister Creek Main Drain system which was developed from the late 1960s to service an industrial using the Australian Rainfall and Runoff (ARR) 19581. Generally, pipe systems were designed for 1 in 5-year Average Recurrence Interval (ARI) storm event. At that time, the compensating basin was designed for a 1 in 10 year ARI storm of critical duration, with 0.3, freeboard. There was no allowance for onsite infiltration which is significant. The run off coefficient was a blanket value of 0.5 with an expectation that some on site compensation was required, no matter the size of the lot. 1 Australian Rainfall and Runoff, Edition 1 First Report of the Stormwater Standards, The Institution of Engineers Australia, Barton, ACT, 1958

of 5

While the ARR 1958 rainfall intensities are slightly higher for shorter duration storm events, they are slightly lower for longer duration storm events compared to the ARR 19872 which is the current design criteria to be applied. Given the slightly higher rainfall intensities of the 1958 ARR for the longer duration storm events, an additional factor of safety is provided to the Compensating Basin with lower rainfall intensities now being experienced for corresponding long duration storm events using the current criteria. Referencing the ARR 1958 method for calculation of peak flow, the site discharge would be in the region of be 2745L/sec during the design 1 in 10-year storm event, based on a time of concentration for the overall site of 31 minutes. The time of concentration was estimated consistent with the ARR1958 principles, using the Friend Equation with a Horton value (surface roughness) based on a paved surface (n = 0.011) and catchment length of 900m. Empirically, the time of concentration appears appropriate given the area and imperviousness of the site. NearMap aerial photography dating back to 2008 also provides verification of the site conditions and assumptions, prior to the subdivision development. For further comparison, the volume of runoff from the entire 39.3 ha of the Swan Brewery site for a 1 in 10 year ARR1958 storm event of 12 hours duration was shown to be within 2% of the equivalent volume using the ARR 1987 method for the same duration, based on a coefficient of runoff of 0.50. Calculations to support each of the above hypotheses are provided at Appendix B of this report. With the permissible site discharge rate of 2743L/sec established (see Appendix B), 1476 L/sec of flow from Municipal Road Reserves (see calculations in Appendix C) has been allowed for a 1 in 100 year ARI storm event. The balance of 1267 L/sec can be used to discharge the stormwater runoff from Lot 1003. Lot 1003 has an area of approximately 6.41 hectares. Assuming a run off coefficient of 0.9, the impervious area will be approximately 5.77ha. To meet the Department of Water criteria of a 1 in 1 year ARI storm of 60 minutes duration, which results in an intensity of 16.4 mm per hour, a retained volume of 865 cubic metres is required before any water can discharge from the site. This volume will be provided within the lot and ensure that this water is discharged by infiltration before there is any overflow into the Water Corporations Vinnicombe Drive Compensating Basin. Therefore, to calculate the additional required storage within the lot will require to investigate the series of storm events up to 1 in 100 year ARI of varying durations to determine a;

1) The peak discharge from the site; and 2) The required onsite storage.

2 Australian Rainfall and Runoff, Edition 3 A Guide to Flood Estimation, The Institution of Engineers Australia, Barton, ACT, 1987

of 5

The maximum discharge from the site has been conservatively set at 1267 Litres per second (original pre-developed site flow rate less flow rate from subdivision Municipal Road reserves). As the calculation of required storage volume has been undertaken graphically rather than numerically using a sophisticated model, an average discharge of 975 L/sec has been assumed from the site. This is approximately 75% of the peak discharge which is in accordance with previous modelling undertaken in such situations. The graphical approach is very conservative as the peak discharge from the site road system will occur at approximately 31 minutes. Based upon the graphical solution using the current 1987 ARR rainfall intensities, it is calculated that the maximum additional volume required to be contained within the site shall be 930 m3. The 1200mm diameter reinforced concrete outfall pipe connecting to the Vinnicombe Drive Compensating Basin to the old Swan Brewery site is also more than capable of discharging the anticipated 2743L/sec total combined flow resulting from rainfall on the Municipal Road Reserve and subject site impervious surfaces during the 1 in 100 year ARI storm event. The capacity of the pipe is in excess of 2648 L/sec at its as constructed grade of 1 in 310. However, as the invent of the pipe is more than 4m below the surface, the hydraulic grade line can easily be increased during peak flow events. At a hydraulic grade of 1 in 270 (2.3m below the surface), the 2743 L/sec total approach flow entering the 1200mm diameter pipe can easily be achieved. Calculations and a graphical solution of this storage volume are provided at Appendix C of this report. It is proposed that the 930 m3 be stored above ground within the car park/access areas at a maximum depth of 200mm according to the provisions contained in AS3500.3 Plumbing and Drainage Part 3: Stormwater drainage. This 930 m3 is additional to the 865 m3 required to retain the 1 in 1 year ARI 60-minute duration storm event on the subject site. The long term duration storm events of between 36 and 72 hours have also been assessed for their effect on total volumetric discharge to the Vinnicombe Drive Compensating Basin. For both long duration storm events, the original design total runoff volume (according to ARR1958) from the 39.3ha Swan Brewery site exceeds that generated by Lot 1003 and the adjacent Municipal Road Reserves for the 1 in 100 year ARI storm event (to ARR 1987). The post developed volumetric totals from Lot 1003 and the adjacent Municipal Road Reserves include allowance for the peak discharge restrictions and infiltration of captured stormwater through native Bassendean Sands to the groundwater table below surface (assuming a conservative long term infiltration rate of 4.3m/day). Calculations are provided at Appendix D of this report indicating the volumetric discharge totals. A concept plan showing the overall proposal to deal with stormwater runoff from associated with the development of Lot 1003 is attached at Appendix E of this report.

4. CONCLUSIONS

Lot 1003 will be developed allowing excess flow and storage capacity from the original design of the area to be utilized to reduce the onsite storage volume to contain a 1 in 100-year storm event of critical duration of site. 865 m3 of underground storage to contain a 1 in 1-year storm of 60 minutes duration will be constructed. This will recharge the groundwater table below the finished surface of the subject site, consistent with WSUD principles a large percentage of all rain fall will be discharged using this method. An addition 930 m3 of above ground storage will be created to deal with peak flows up the 1 in 100 year ARI storm event of critical duration. The Water Corporation or City of Canning systems will not be compromised, nor over loaded. with respect to the development of Lot 1003 proceeding.

Appendix A Calculation of Lot 1003 storage volume to meet WSUD principles

A1

Calculation of storage required to meet Department of Water WSUD principles Using the Rational Method, the volume of stormwater to manage stormwater runoff from constructed impervious surfaces generated by the 1 in 1 year ARI storm of 60 minutes duration, at its source consistent with Water Sensitive Urban Design (WSUD) principles, is calculated as follows:

= 60

360

Where: V is the volume of stormwater in (m3); d is the storm duration (60 min); C is the C10 runoff coefficient based on the impervious surface area and the 1-hour

duration storm intensity according to ARR1987 0.90 for Lot 1003 with a site fraction imperviousness of 1.0;

I is the rainfall intensity in (mm/h) 15mm/h, and A is the catchment area (ha) 6.411 ha for Lot 1003.

Computing the above, the total volume of stormwater in 60-minute duration storm event to be retained on site to meet Department of Water requirements is 865 m3. This volume is proposed to be stored below ground and infiltrated through native sands to recharge the groundwater table well below the finished ground surface.
