RE: WATER MANAGEMENT REPORT FOR PROPOSED EXPANSION AUSTRALIAN CHRISTIAN COLLEGE – LOT 90 DP1224210 FARM ROAD

RIVERSTONE

1.0 Introduction Demlakian Consulting Engineers have been commissioned to prepare stormwater and water management concept plans for the proposed development at the above site. These plans and this report have been formulated to address the requirements of Blacktown City Council Development Control Plans, in particular Part J, Water Sensitive Urban Design and Integrated Water Cycle Management (2015).

This report should be read in conjunction with Demlakian Consulting Engineers Drawings 213025/ SW00 to SW011 (Revision N) which outlines the proposed storm water management system. Reference should also be made to the Architectural Drawings prepared by Lippmann Partnership, on which basis this report has been prepared.

The Australian Christian College is currently located at Farm Road Riverstone (Lot 90 in DP1224210), and consist of a number of school buildings and demountables. A previous Development Application was submitted and approved for the construction of an additional school building on this property. (Determination No: 13-634 dated 27th June 2013). Subsequently the school has purchased the above site, and this current submission is to locate a building similar to the above approval on the more recently purchased site. This site currently contains a domestic dwelling and several outbuildings. In addressing the water and storm water management issues, a similar approach has been taken to the previously approval, and similar design parameters have been adopted to those previously discussed and agreed with Council.

2.0 Proposed Development The works involve demolition of the existing site structures, filling of some existing farm dams, construction of a new three storey building with associated ground level pavements and

car parking. The works include the construction of link roadways, storm water drainage and other infrastructure. The proposed development will only affect the North portion of the Lot, as indicated in Figure 1. The affected part of the site has an area of 0.947 hectares (“Design Area”). Since the remainder of the site essentially remains in its existing state it has not been considered as part of the Design Area. The design area of the site generally consists of vegetation, with some small buildings and a dam. The development proposes the construction of a new three storey building, a carpark and a bus turning bay, as shown in the Drawings. All runoff from landscaped and paved areas will be directed through a series of pits containing enviropods to an onsite detention (OSD) tank located beneath the new roadway and through a proprietary water quality treatment device within the onsite detention tank. The new driveway/bus bay area proposed on the pre-existing school site was approved as part of the previous DA and as per previous conditions, runoff from this area will only be treated by an existing gross pollutant trap at the downstream property boundary. The roof area of the new building will drain to rainwater tanks and serve as reuse water. Overflow from the rainwater tanks will also be directed to the OSD tank. The site is also impacted by an upstream catchment located to the east. Since the proposed location of the new building impacts the current overland flow through the property, this flow will be intercepted and bypassed through the site in a piped drainage system. Approximately 60% of the design area is proposed to be impervious surfaces, such as roofs and pavements, with the remainder to remain as lawns and landscaping.

Figure 2 – Upstream Catchment

3.0 Storm Water Management Strategy

The site is currently accessed from Farm Road and is surrounded by rural residential properties to the east and south and the existing school to the west. The site is relatively flat in nature with a minor slope running from East to West. Key issues for the site relate to water conservation, control of storm water flows and flooding impacts on adjoining properties, and water quality control. The site parameters and the proposed site layout lend themselves to an efficient control of the above factors. The attached storm water management drawings indicate the manner in which these objectives are achieved. A summary of key factors is outlined in the following sections of this report.

The following strategy has been adopted to manage the impacts from storm water. Upstream Overland Flow As noted above the site is impacted by an upstream catchment located to the east of Lot 8. Since the proposed location of the new building impacts the current overland flow through Lot 8, this flow will be intercepted and bypassed through the site in a piped drainage system. To ensure flows to not pond on the property to the east of the site the proposed driveway aisle and car parking will be constructed at a level at or below the existing boundary level. Flow will be allowed to enter the site at the existing low point and will be collected in a large grated entry pit. From this point the overland flow will be bypassed through the site to the existing 300x900 box culvert located at the front of the school property and thence to the existing headwall located in the north-western corner and discharging to the west of the current school site.


The proposed bypass pipeline will consist of twin 900 mm diameter pipes. Twin pipes have been adopted to allow for redundancy in the case of partial blockage. The large entry pit has been adopted to minimise the impact of partial blockage of the pit grating. The twin pipes will be provided under the driveway to a point in front of the existing school. At this location a surcharge pit will be provided with a connection to the existing 300 x 900 box culvert. In the event of full blockage of the 300x900 box culvert the flows in the system will have a downstream control of RL19.050 at which location the twin pipe system will surcharge and flow overland across the existing overland flow channel formed in the entry driveway to the existing school. This is in accordance with the design parameters approved by Council at the time of construction of the school based on a design provided by Healy Castle and Associates and approved by Council. The performance requirements of this system are as follows:

• As previously agreed with Council Engineers at the time of Determination No: 13-634 dated 27th June 2013, the catchment to the east of the site was determined as 5.66 hectares. Refer to Figure 2 for the catchment diagram.

• A time of concentration of 10 minutes was agreed for the flow, with a subsequent 100 year ARI rainfall intensity of 167 mm per hour.

• A runoff coefficient of 0.58 was agreed. • A design flow of 1.52 cubic metres per second was adopted. • Calculations are presented on the drawings demonstrating the hydraulic grade line in

the 1% AEP event allowing for full blockage of the 300x900 culvert, and 25% blockage in each of the 900 mm diameter pipes. As demonstrated the system flows adequately with an upstream ponding depth of 150 mm maximum which is anticipated to be less than the upstream flow depth.

Accordingly the proposed piped bypass system meets the requirements for diverting the upstream overland flows in the event of a 100 year ARI storm event. Drainage from Proposed Building and Pavements Stormwater runoff from the roof of the new structure will be drained to in-ground rainwater tanks located on the western side of the building. Collected roof water will then be re-used for toilet flushing and irrigation of landscaped areas thus achieving the water conservation objectives. In addition water tanks serve a valuable purpose in reducing pollutant loads in the storm water discharge from the site and also reduce the quantity of water discharged.

Ground surfaces will be directed to an on site detention tank that will be installed beneath the new section of roadway. Water quality objectives will be achieved by draining surface flows through pits containing enviropods and onto a proprietary water quality treatment device being installed within the on-site detention tank. This will treat the stormwater runoff before it leaves the site and allow it to achieve the water quality treatment objectives.


4.0 Water Conservation Measures A spreadsheet has been created to demonstrate that the frequency of overflow draining from the site post development does not exceed the frequency of overflow exiting the site prior to construction. A summary page is enclosed with this report.

The spreadsheet has been created using the daily rainfall data produced by the Bureau of Meteorology over a 20year period (1992-2012). To calculate the water overflowing from the design area into the neighbouring property to the west for the post construction site layout, the daily runoff from the paved and unpaved areas of the site has been calculated and added where applicable to the overflow volume from the rainwater tank. The spreadsheet calculates the volume of overflow on a day to day basis and on days where the volume of the water tank has been exceeded the runoff into the neighbouring property has been calculated. From this spreadsheet it was calculated that the site overflowed into the neighbouring property a total of 1812 days in 20 years in accordance with the developed conditions. Therefore overflow occurs 25.4% of the time and there is a total of 172,701 cubic metres of overflow over 20 years. For the pre-developed site, storm water from the same site area that has not infiltrated into the soil has flowed directly into the neighbouring property to the west. From this spreadsheet it was calculated that the site overflowed into the neighbouring property a total of 1791 days in 20 years. Therefore overflow occurs 14.2% of the time and there is a total of 152,155 cubic metres of overflow over 20years. Therefore there is an increase in overflow volume between pre and post development of 13%. Whilst water tanks provide for storage and water consumption, an onsite detention tank is required to reduce the peak site runoff in the post developed case. Refer to Section 5- Stormwater Quantity Modelling.

The daily water usage from the rainwater tank for flushing of toilets was calculated to be 2,700 L/day from the daily water usage rates supplied by The Government of South Australia in the document Water Smart: Rainwater Tanks for Toilet Flushing. Additionally, 1,500 L/day was allowed for drip irrigation based on the requirements for the landscaped areas on the property. Therefore the total daily water usage from the rainwater tank for the post-developed property is 4,200 L/day. Further, it is assumed that as there are no rainwater tanks on the pre-developed site the daily rainwater tank usage is zero in the pre developed case. In the post construction design of the site all of the roof area of the new structure is being drained to the rainwater tanks which are reusing the collected water to flush the toilets and provide drip irrigation to the surrounding landscaped areas. Using the assumptions previously stated that the site requires 2700L/day from the rainwater tank for irrigation purposes and 1500L/day for flushing of the toilets, the excel spreadsheet has calculated the amount of water entering and leaving the tank each day and summed the amount of days that there was not enough water for irrigation and toilet flushing purposes. In 20 years, the rainwater tank will be empty 1226 days which is equal to 16.8% of the time. Therefore in 20 years the rainwater tank is adequate for supplying the developments non potable demand for water 80% of the time.

Thus, the water conservation objective of for 80% of the sites non potable demand to be fulfilled using non potable sources, as per section 4.3 of the Blacktown Development Control Plan 2015 is achieved.


5.0 Storm Water Runoff Management The Development Consent Conditions (Determination No: 13-634, Condition 6.11.2.1) issued by Blacktown City Council in response to the previously approved DA submission, state that onsite detention of stormwater runoff from the site must be provided to achieve the following:

i. Nominated Discharge PSD: 147l/s/ha for 100%; 101l/s/ha for 90%; 562l/s/ha

for 80% ii. Nominated Storage SSR: 264 cu.m/ha for 100%; 301 cu.m/ha for 90%; 473

cu.m/ha for 80% As 100% of the developed area will drain to the on-site detention tank, the following permissible site discharge and site storage capacity have been calculated: - Site Area Draining to OSD= 0.947 ha (100% of the developed site area) - PSD = 147 l/s/ha (for 100% of the developed area being directed to the OSD tank) = 147 x 0.947 = 139 l/s - SSR = 264 cu.m/ha (for 100% of the developed area being directed to the OSD

tank) = 264 x 0.947 = 250 cu.m


6.0 Storm Water Quality Modelling Stormwater Quality: Urban development increases the pollution load entering local waterways. All developments in the Blacktown City Council are required to meet minimum treatment objectives in accordance with Table 2 of the Blacktown Development Control Plan 2015. The following stormwater quality load reduction controls are required:

i. 90% reduction in the post development mean annual load of Gross Pollutants (GP) ii. 85% reduction in the post development mean annual load of Total Suspended Solids

(TSS) iii. 65% reduction in the post development mean annual load of Total Phosphorus (TP) iv. 45% reduction in the post development mean annual load of Total Nitrogen (TN) v. 90% reduction in the post development mean annual load of Total Hydrocarbons

(TH)

These pollution load reductions have been modelled using Model for Urban Stormwater. Improvement Conceptualisation (MUSIC). The proposed development has been modelled MUSIC by Storm Water 360 on our behalf. (files available on request). - Figure 4 shows a schematic of the Music model. A summary of inputs and assumptions are outlined below.

Figure 4: Music Model Schematic As approved for the previous DA, the following has been adopted: - Roof to Rainwater Tank - Overflow from Rainwater Tank to Onsite Detention Tank - Landscaping to Onsite Detention Tank - Overland Flow from adjoining properties piped to Existing Headwall


7.0 Flood Emergency Response Plan The 1 in 100 year flood level in the area of the site has been calculated at 17.3m as obtained from a council letter dated 22nd February 2013 (File no: 120315/3). This is well beneath the lowest proposed floor level of the site. The proposed construction has a Floor Level RL= 19.8. Therefore, the development is not affected by the Flood Planning Levels within the area. As presented in Figure 5, the 1/100 year storm will only affect a small portion of the site located on the western boundary of the site. This storm event will impact the site at the approximate location of the car park but not approach the buildings. Therefore, during this storm event there should be no need to evacuate the school.

Figure 5: Flood Zoning Map The site is affected by the Probable Maximum Flood (PMF) level. This level as obtained from a council letter dated 22nd February 2013 (File no: 120315/3) is calculated as 26.4m in the area. This is 6.6m above the floor level of the proposed building. If evacuation from the site is required during an event of this nature, adequate warning times would be provided as a vast area surrounding the site will be affected. The areas highlighted in white in Figure 5 are not affected by the PMF. The following route should be taken by inhabitants of the school to access safe areas that are not affected by the PMF and to prevent crossing areas that are affected by the 1/100 year storm event:

- Exit the site from the Southern boundary and cross through the neighbouring properties to reach Robert Street.

- Travel South along Robert Street past the Walker Parade intersection. The area south of this intersection is not affected by the PMF.

Should road access be required the following route should be taken, however it should be noted that a small section of Farm Road subject to the 1/100 year flood will need to be crossed:


- Exit the site and travel East down Farm Road - Turn Right onto Cleveland Road - Turn Right onto Walker Street - Turn Left onto Robert Street. The area south of this intersection is not affected by

the PMF. Enclosed is a copy of the Emergency Flood Management Plan that the school will implement to ensure a safe flood emergency evacuation plan.

8.0 Conclusion The development of the site has been designed to ensure that there is minimal increase to the stormwater runoff flow rate from the site and will mitigate negative impacts on the surrounding properties both in routine and extreme events. The proposed drainage plan complies with the requirement of section 4.4 of the Blacktown Control Development 2015 which limits the post development flow of water from site to the predevelopment flow. The rainwater tanks proposed as part of the new construction will have a combined storage of 100,000L. The volume of these tanks ensures that the sites demand for non potable water is 80% satisfied by non potable sources. Therefore, the design satisfies section 4.3 Water Conservation of the Blacktown Development Control Plan 2015. The stormwater quality and treatment solution proposed has been designed to ensure that Blacktown City Council treatment targets and requirements are reasonably met. The design ensures that stormwater off the site as a result of the new construction will have limited effects on the downstream water quality. Yours Faithfully,
