CHAPTER ONE

Introduction

1 Introduction:

1.1 Introduction RCMB’s Residential Subdivision Guidelines document has been prepared to encompass the following goals: Provide guidance on engineering documentation requirements for residential land development projects

Assist Developers, and other practitioners/professionals to meet RCMB expectations in the design, specification and construction of residential subdivisions

Maintain a consistent quality management framework in which RCMB and developers can operate. The document is divided into 7 sections; Applicant Responsibilities, Road Network Assets, Stormwater Drainage Assets, Earthworks Design, Landscaping and Open Space, Site Management, and Quality Assurance Requirements. The section on Applicant responsibilities has been provided to guide the Applicant on their responsibilities during the different stages of the land division process. -Its objective is to provide a quick reference or checklist for each step, to assist in meeting RCMB expectations and requirements. Subsequent sections provide guidance on documentation requirements, design, and construction of particular assets. The aim of each section is to provide clear direction on suitable design standards for infrastructure. Requirements are based on local experience and industry guidelines. Section 7 refers to Site Management and aims to highlight the developer/contractors responsibilities for compliance with relevant acts during the construction phase of works. RCMB requests that the information is forwarded to them for their records; however they do not assume responsibility for checking all documentation for compliance with relevant legislation. Quality Assurance Requirements are detailed in Section 8. Assets are to be designed and certified by appropriately qualified persons, and documentation provided to professional standards. Hold Points and submission of testing results are to be included in an Inspection and Testing Plan prepared specifically for the works. Test results need to be submitted in appropriate timeframes to ensure completed assets are acceptable. Bonding and Retention Money arrangements are also discussed.

CHAPTER TWO

Responsibilities

of the

Applicant

2 APPLICANT RESPONSIBILITIES:

2.1 Applicant Responsibilities

2.1.1 Engaging Consultants The Applicant should engage the services of qualified and experienced consultants for the preparation of designs and supervision of subdivision works to meet all design and construction requirements and conditions specified by RCMB for the purposes of the development proposal. For construction of roads, bridges, drains and services, required as a condition of land division consent, the Development Act 1993 and Development Regulations, 2008 require detailed construction plans and specifications to be signed by a professional engineer, or at the discretion of the council, a licensed surveyor, and approved by council before the commencement of work. A professional engineer means a person who is eligible for full membership of the Institute of Engineers Australia or registration on the National Professional Engineering Register. Design and supervision of all Civil Works should be carried out by a professional engineer. In this guideline the nominated professional is referred to as the Principal Consulting Engineer. Design and supervision of Landscaping Works should be carried out by a qualified practicing landscape architect.

Rural City of Murray Bridge, V 1.0 2-1

2.1.2 Service Authorities The Applicant / Developer are responsible for all liaisons with the relevant Service Authorities in relation to provision of the services to each individual allotment. Requirements of the respective service authority shall be fully met by the Applicant. These services include: -

• water reticulation and services;

• electrical reticulation including service pillars;

• telecommunication;

• street lighting;

• conduits and pits for telecommunication services;

• gas reticulation and services; and

• wastewater treatment and disposal services.

• DPTI

• Railway Authority All public utilities (water supply, sewer, power, gas and telecommunications services) are to be installed underground. In accordance with the Development Regulations, before the roadway of any proposed road is sealed, the applicant must satisfy the council that all connections for water supply and sewerage services, which need to be laid under the surface of the proposed road, have been made. Where it is necessary to provide mains or service connections across existing roads, RCMB’s preferred method of connection is via directional horizontal boring. Any area disturbed during the installation of services is to be reinstated to the satisfaction of RCMB. For further information on reinstatements in the road reserve refer to Section 3.8. RCMB first preference for wastewater disposal is connection to SA Water. Where connection is not available, a concept plan indicating the proposed method to deal with the collection treatment and disposal of sewerage and sewerage waste is required. Developers may need to consider Community Wastewater Management Systems (CWMS). The Wastewater Management section of the Department of Health, SA should be contacted to provide guidance on the most up to date Design standards, Legal Requirements, and Application requirements of CWMS.


2.2 Land Division Approval Process The Land Division approval process involves three stages. The first stage is Development Approval. The second stage is Section 51 Clearance. The applicant is responsible for the final stage, which is submission to the Lands Titles Office. The applicant must obtain a Section 51 Clearance before they can lodge plans with the Lands Titles Office. The Development Approval stage involves two parts. Initially the application is assessed against the relevant provisions of the Development Plan. Once a satisfactory concept is developed, further detail is usually required to complete the assessment of the Land Division, which usually relates more to the engineering requirements. Section 2.2.1 provides guidance on the information requirements that may be required for RCMB to complete its assessment of a proposal. Following approval of the land division the applicant must seek Section 51 clearance. Land division approvals, usually contain a number of land division conditions, relating to the standard of the roads, stormwater system, or other physical improvements to the land. Section 2.2.2 and Section 2.2.3 outline the documentation requirements that RCMB may require to ensure that RCMB can provide Section 51 clearance of land division conditions.


2.2.1 Prior to Development Approval Prior to Granting Development Approval, RCMB’s Engineering Department will need to:

• be satisfied that the development will; a) adequately cater for future vehicular traffic, b) include appropriate provision for non-vehicular traffic such as pedestrians and cyclists, c) make due allowance for major stormwater flow paths and detention or retention areas, d) meet the goals, strategies, and objectives of the RCMS’s Stormwater Management Plan (SMP) and Integrated Water Resources Management Plan (IWRMP).

• have a full appreciation of any potential impacts of the development upon the environment, neighbouring lands, adjoining developments, and existing infrastructure.

• understand the proposed order of development including; a) the staging of the development b) the construction schedule c) the release of land schedule. d) the broader implications of the impact the development will have on the existing stormwater network and other existing infrastructure.

To assist RCMB in its deliberations on these broader scale and long term issues, the Applicant / Developer may be requested to provide: -

• A Site plan showing any existing structures, contours, and proposed

regrading. The details may be incorporated in to the preliminary Road Layout or Stormwater Concept Plan.

• A Road Layout Plan. The degree of documentation will vary depending on the nature and size of the proposed development. For a guide on the minimum requirements see Section 3.2.

• A statement and if necessary a plan, listing estimated traffic flow

figures for the development. This statement or traffic impact plan should be prepared by a suitably qualified person.

• A report on the geotechnical investigations undertaken for the site.

The degree of investigation required will vary depending on the site and the proposed development. For a guide on the minimum requirements for geotechnical investigations see section 5.1.1.


• A Conceptual Stormwater Management Plan and a Water Quality Improvement Plan. The degree of documentation will vary depending on the nature and size of the proposed development. For a guide on the minimum requirements see Section 4.2.

• A Concept Open Space Plan for the whole development setting out

the location type and size of the area for all proposed public open space and proposed function.

• A landscaping concept plan addressing streetscape, site conditions,

design intent, and irrigation demand and source.

• An Existing Trees Survey Plan setting out the location of all existing trees with diameter in excess of 400mm on the development site and within 5 metres of the site boundary. For a guide on the information to be included on the Existing Trees Survey Plan refer to Section 6.3.3.

• A Concept Plan indicating the proposed method to deal with the

collection, treatment and disposal of sewerage, and sewerage waste (including wastewater) from the site.

• Details of the construction staging and an indicative timetable.


2.2.2 Pre-Construction Prior to commencement of construction the developer will need to obtain approval from RCMB of the proposed construction details and specifications for the project, and complete the Pre-Start Meeting Process. The Pre-Start Meeting Process is part of RCMB's quality management framework. The process involves completing a checklist, to verify that all necessary procedures and documentation have been undertaken prior to commencement of works, and a site meeting to provide an opportunity to go through the approved documentation and clarify the relevant conditions and construction requirements. Once approval of construction details has been obtained from RCMB, the Principal Consulting Engineer should complete the Pre-Start Meeting Checklist and submit to Council at least 7 days prior to commencement of works. A copy of the Pre-Start Meeting Information Checklist is included in Appendix 3. Prior to commencement of any work on site the following data as being relevant to a specific stage, must be submitted to RCMB:

• Final road construction drawings including road layout and geometry, signs and linemarking, pavement design, lighting, footpath and shared paths, and special driveways. For further information see Section 3.2

• Final Stormwater Construction Plans, including detailed construction

drawings for all stormwater infrastructure for the stage. For further information see Section 4.2

• A detailed Landscaping and Open Space Plan incorporating

construction details, planting schedules, and a technical specification. For further information see Section 6.2.

• An Irrigation Management Plan. For further information see Section

6.3.8

• A Soil Erosion and Drainage Management Plan. For further information see Section 7.3.

• A copy of the final electrical reticulation drawings, showing the

locations of all transformers, HV switching cubicles and street lighting.

• Technical Specifications and Tender Details.


• Construction Schedule, Inspection and Testing Plan (refer Section 8.3), and Construction Management Plan (refer Section 7.2).

A work permit via the RCMB Application form - Authorisation to alter a public road, must be obtained prior to any work being undertaken within or on RCMB’s road reserve area. A separate agreement form may be required with The Department of Planning, Transport and Infrastructure (DPTI) where works will occur on or adjacent to a road under the care and control of the Commissioner of Highways. It is the Applicant’s responsibility to seek and, if necessary, comply with such an agreement. The applicant is also responsible for obtaining any approvals necessary for the works from other authorities such as the Environment Protection Authority or the Murray-Darling Basin Natural Resources Management Board. The Applicant / Developer shall also submit for each stage of the development a Combined Services Plan (hard copy, presented at a scale 1: 1,000 or larger, and an electronic copy in pdf format). The combined services plan shall clearly show all cadastral information and locations of services including water, sewer, stormwater, and street lighting details.


2.2.3 Prior to Section 51 Clearance Prior to Section 51 Clearance the developer will need to complete the Engineering Clearance Process. The Engineering Clearance Process is part of RCMB's quality management framework. The process involves completing a checklist, to verify that all necessary procedures and documentation have been undertaken, and a site meeting to review and discuss the various components of the works. A copy of the Engineering Clearance Meeting Information Checklist is included in Appendix 3. The Principal Consulting Engineer should only request Engineering Clearance once all the relevant requirements in the check list are complete. The Checklist should be completed and submitted to RCMB at least 7 days prior to the requested meeting date. Prior to granting Engineering Clearance, the Applicant/ Developer will be required to supply the following information to the satisfaction of RCMB:

• An A1 hard copy of the “As Constructed” Drawings for all civil works. All deviations and changes from the For Construction drawings are to be noted and certified by the Principal Consulting Engineer.

• An electronic copy on labeled CD of the “As-Constructed” drawings for

all infrastructure assets in an AutoCAD format supplied in GDA94 MGA Zone 54 and in accordance with the following;

• Separate layers for Roads Assets, Stormwater Assets, Property and

Easement Boundaries, and any other infrastructure.

• The Roads Assets layer shall include the Gazetted road names, Road Centreline, Kerbs, and Footpaths. Attributes of all elements shall be included, such as width, type and materials.

• The Stormwater Assets layer shall include location of all surface

inlets, structures, pits, pipes and outlet structures. Attributes of all elements shall be included, such as Depths, size, and materials.

• A schedule or register of all the infrastructure that will become the

property of RCMB in tabular Excel format listing for each element the location, dimensions, materials, construction date, design life, and maintenance requirements.

• Specifications, Manuals, and Maintenance schedules for any

stormwater quality improvement devices (such as constructed wetlands or ponds, Gross Pollutant Traps, and infiltration systems) detailing the expected ongoing maintenance activities required for the asset.


• Any outstanding Quality Assurance Requirements as detailed in Section 8

• An allotment plan showing the extent and the depth of filling on all

allotments together with a site re-classification for residential footing design, from a suitably qualified professional engineer.

• Certification from the Principal Consulting Engineer, responsible for the supervision of the project, that the development has been constructed in accordance with RCMB approved plans and specifications.

• Copies of all easements to be provided to RCMB and all other Service Authorities.

Bank Guarantees, retention monies for the defects liability period, and bonding arrangements or monetary contribution agreements must be resolved and finalised prior to any Section 51 Clearance being issued by RCMB for the development. For further information regarding bonding and retention monies refer to Section 8.5.


2.3 Final Works Acceptance At the conclusion of the defects liability period the Final Completion Process is carried out. The Final Completion Process is part of RCMB's quality management framework. The process involves completing a checklist, and a Joint Final Inspection. A copy of the Final Completion Meeting Information Checklist is included in Appendix 3. The Principal Consulting Engineer should only request a meeting once all the relevant requirements in the check list are complete. The Checklist should be completed and submitted to RCMB at least 7 days prior to the requested meeting date. Once Final Completion requirements have been satisfied, the developer needs to apply for transfer of ownership of assets to RCMB, and the return of retention monies. The RCMB will execute the termination of the bonding (retention monies) agreement and issue a Certificate of Transfer for the assets. The Final Completion Meeting Information Checklist requires submission of CCTV Footage of internal inspection of all stormwater pipe networks. For specific requirements of CCTV Footage of internal inspection of all stormwater pipe networks see Appendix 2 CCTV Pipe Surveys.

2.4 Liabilities and Insurances

In accordance with Section 245A of the Local Government Act the developer may be required to enter in to a bonding agreement for repairing any damage caused to Council footpaths, roads, kerbing and stormwater pits by inappropriate use of trucks, excavators and other heavy equipment while entering and exiting the construction site. The Developer is responsible for all damage to existing facilities, services and structures sustained as a result of the development of the subdivision, whether those damaged items are in public or private ownership. All damage is to be promptly reinstated to an equivalent standard acceptable to the owner. RCMB will require the Developer to take out all necessary insurance policies to indemnify and protect it and RCMB against any claims that may arise in undertaking the development, until Final Works Acceptance has been obtained from RCMB.


CHAPTER 3

ROAD NETWORK ASSETS

3 ROAD NETWORK ASSETS

3.1 Introduction The road network assets associated with a residential subdivision need to fulfil several functions. Street layout and design should create “A hierarchal street network, which provides for safe and convenient movement, accommodates public utility services and drainage systems, and creates an attractive environment.” - Good Residential Design SA: A resource for planning, designing and developing neighbourhoods and homes, Government of South Australia, 1999. The RCMB Development Plan provides a range of objectives and principles of development control relating to road network assets. Particular reference should be made to the general sections relating to Transportation and Access and Land Division.

3.2 Documentation Requirements Access arrangements are to be submitted with development proposals and should show as a minimum;

• Road hierarchy; • Typical cross sections showing the carriageway widths and the proposed location of services; • Connections to existing streets; • Pedestrian paths and crossings; • Parking provisions (on street and off street where applicable); • Any physical traffic control devices; • Bicycle routes and shared paths;

Proposals that include the construction of public roads will need to provide evidence of consultation with the Public Transport Division of the Department of Planning, Transport and Infrastructure (DPTI) regarding bus routes and bus stops. Prior to commencement of work Final Road Construction Drawings and a specification prepared specifically for the works under consideration, are to be submitted to and approved by RCMB.


Final Road Construction Drawings should detail;

• Road layout and geometry including Plan views and longitudinal sections, Cross sections, Intersection details and traffic management measures.

• Signs and linemarking • Site regrading details including the extent of any site filling and cutting,

and how these will be treated at the boundary of the road reserve. • Road pavement design including all design criteria

• Parking and driveway plan (including the location and width of splays in

relation to driveway openings at the boundary of each allotment).

• Detailed drawings of any special treatments including pavement widening, special driveways.

• Lighting Plan with luminary, light poles and standard of design details,

and SA Power Networks public lighting agreement document completed by the designer.

• Footpath and shared path details.

3.3 Road Hierarchy and Geometry RCMB has adopted the street classification system detailed in Table 3.3: Standard Residential Road Design Elements. This table sets out the general minimum standard of design elements for the various road classifications.

3.3.1 Street Definitions

• Access Lane An Access Lane can be used for access to a small number of allotments, and should be restricted to a maximum length of 50m. It would typically be a short cul-de-sac. RCMB Typical Detail Drawing No. 2012-5006-001 located in Appendix 5 Drawings depicts the typical cross section of an Access Lane.


• Access Road An Access Road is dominated by the residential environment. The number of dwelling units served should not exceed 30 and the layout of the subdivision should be designed to limit the length of the street to less than 150m. RCMB Typical Detail Drawing No. 2012-5006-002 located in Appendix 5 Drawings depicts the typical cross section of an Access Road.

• Local Streets

A Local Street is one in which the residential environment is dominant, traffic is subservient. The number of dwelling units served should not exceed 100. Speed and volume are low, with a footpath required on at least one side of the road. Vehicle speeds are typically controlled by street length and /or alignment. RCMB Typical Detail Drawing No. 2012-5006-003 located in Appendix 5 Drawings depicts a typical cross section of a Local Street

• Collector Road

Typically a Collector Road is used to concentrate local traffic to an outlet to the Arterial Traffic Road System, without attracting through traffic itself. It will often be designated as a bus route. It will also have wide verges to accommodate pedestrian or shared paths on both sides of the road. There should be no pedestrian movement across it other than at controlled crossing locations. RCMB Typical Detail Drawing No. 2012-5006-004 and 2012-5006-005 located in Appendix 5 Drawings depicts a typical cross sections of a Collector Road. • Rural Road A Rural Road is used in a country or rural environment where the allotment size is considered large enough not to require a concrete kerb and channel. Swale drains are required both sides, with box culverts to service each driveway. Intersections and cul-de-sac’s shall be sealed with an approved AC treatment (Hot Mix). Footpaths are generally not required on a Rural Road, however the RCMB will assess its merit during the development assessment phase. RCMB Typical Detail Drawing No. 2014-500-001 located in Appendix 5 Drawings depicts a typical plan view and cross sections of a Rural Road.


3.3.2 Street Pattern The various street types defined above should be arranged in a logical pattern relative to their respective hierarchy in recognition of the inter-relationship between the various residential types and functions. Further guidance on design of street pattern can be found in “Good Residential Design SA: A resource for planning, designing and developing neighbourhoods and homes”, Government of South Australia, 1999.

3.3.3 Roads within Community Title Land Community Title developments are required to provide access for pedestrians and vehicles, including all those expected to service the development, such as garbage trucks, furniture removal trucks, and fire control vehicles. Adequate treatments will need to be incorporated in the internal access arrangements to enable all vehicles servicing the development to enter and exit in a forward direction. RCMB garbage service vehicles will not normally enter community title developments as the roadways are on private land, not public roads. Exceptions to this may be negotiated between the developer and RCMB where the roads are designed and formed to RCMB specifications to carry garbage vehicles and the owner indemnifies RCMB against any damage to the roadway. Where a developer does not wish to construct roads capable of accommodating the regular garbage service vehicle, they may be required to provide a collection area within the common property of the development and evidence of an arrangement with a private contractor for provision of a garbage collection service. Details of internal roads including layout and pavement design shell be provided during the assessment phase.


3.3.4 Carriageways and Road Reserve Widths Minimum carriageway widths for all road classifications are shown in Table 3.3: Standard Residential Road Design Elements. All road reserves shall be able to accommodate the requirements for footpaths, landscaping, drainage, underground services, street lighting columns, and safe vehicle entry and egress from every individual property. Application of Water Sensitive Urban Design principles is to be considered at all times. Where WSUD approaches are used, flush kerbing is to be provided, as a minimum, to protect the edge of pavement. The street network, including all intersections and T-junctions, must be able to accommodate the AUSTROADS 12.5 metre Single Unit Truck (Austroads Design Vehicles and Turning Path Templates, 2006) without the need for the mounting of kerbs by leading or trailing wheels. Local widening may be required on small radius bends. Cul-De-Sac head layout is to be in accordance with RCMB Typical Detail Drawing No. 2013-5002-001. The design vehicle used is the current garbage service vehicle which has a turning circle of 17.5 metres and a swept path of 18.6 metres. Cross fall on street pavements is to be a minimum of 3.0%. One way cross-fall may be permitted on slopes where one way cross-fall will reduce the amount of earthworks required or for WSUD cross sections. Where the Developer proposes to use geometry that differs from those in the appendix 5 (2012-5006-001 to 2012-5006-005), full details will need to be presented to RCMB for consideration.

3.3.5 Design Speeds The general urban speed limit in RCMB is 50km/hr. Subdivision layout and the use of appropriate traffic control devices in street design should be used to limit speeds to those defined in Table 3.3: Standard Residential Road Design Elements

3.3.6 Longitudinal Gradient Longitudinal gradient is to conform to the limits as shown in Table 3.3: Standard Residential Road Design Elements. Vertical curves are to be used on all changes in grade exceeding 1%.

CHAPTER 4

Stormwater Drainage Assets

4 STORMWATER DRAINAGE ASSETS

4.1 Introduction Stormwater management forms an integral part of any development. The RCMB (May 2007) ‘Stormwater Management Plan’ (SMP) and the RCMB (July 2008) ‘Integrated Water Resources Management Plan’ (IWRMP) are the strategic framework, in terms of planning for and managing stormwater and runoff from existing and future developments within RCMB. General factors noted for the Murray Bridge area include:

• Flooding has been a major issue in areas of Murray Bridge over recent years with the major 100 year ARI event being exceeded with an estimated 200-300 year ARI event;

• Seasonal and annual variability in rainfall; and

• High rates of evaporative losses. These factors should be considered in planning and designing stormwater management systems, and the selection and design of stormwater quality improvement devices.


4.2 Documentation Requirements Prior to finalising the assessment of a proposed development RCMB must ensure that the approved development will be provided an adequate degree of flood protection, and that the stormwater management system will adequately treat and dispose of any stormwater generated by the development. The nature of the proposed development will determine the level of information required to be submitted as part of the development application. For all developments, site plans submitted as part of a Development Application should show the following:

• Existing site levels or contours with adjacent road, kerb and drainage invert levels.

• Finished surface levels relative to estimated flood levels. • Proposed levels and grading of pavement. • Conceptual layout of the proposed drainage system and outlet. • The location, positioning and type of proposed Stormwater Quality

Improvement Devices (SQID). • Delineation and area of all sub-catchments. • Minor stormwater flow paths (minQ5), and flow path for the major

event (Q100) A Water Quality Improvement Plan (WQIP) will also be required. Section 4.3.3 discusses the requirements of WQIP's. Engineering calculations may also be required to demonstrate that sufficient space has been allocated to stormwater management infrastructure. In relation to any proposed permanent water bodies predictive modelling will be required of the impacts of the proposed basin on both groundwater quality and water table levels, and geotechnical data upon which the modelling is based. Prior to commencement of any works on site detailed construction plans and specifications are to be submitted to and approved by RCMB. Final Stormwater Construction Drawings should include:

• A General layout plan at a suitable scale showing, Catchment Area, Design Contours, and the general layout of the drainage system, including all drainage easements, reserves and natural water courses.

• A drainage system layout plan at a suitable scale showing pipeline

location, drainage pit location and number, road centreline chainage, and the location of any basins and SQID.

• The drainage system longitudinal sections showing the pipe size, type

and class, road chainages, pipeline grade and hydraulic grade line.


• Detail plans at a suitable scale for all non-standard pits, open channel

designs, and SQID.

• Details of any temporary works, drains or banks proposed as part of the development project.

Engineering calculations may be requested for audit should it be deemed necessary by RCMB.


4.3 Stormwater Drainage Design The following goals, as detailed in the SMP apply to stormwater drainage design in the RCMB. Goal 1: Flood Management • Provide and maintain an adequate degree of flood protection to existing and future development. Goal 2: Water Quality Improvement • Improve water quality to meet the requirements for protection of the receiving environment and downstream water users. Goal 3: Water Use • Maximise the use of stormwater runoff for beneficial purposes while ensuring sufficient water is maintained in creeks and wetlands for environmental purposes. Goal 4: Amenity, Recreation & Environmental Enhancement • Where possible, develop land used for stormwater management purposes to facilitate recreation use, amenity & environmental enhancement. Goal 5: Asset Management • Ensure the condition of stormwater infrastructure is suitable for its intended purpose.

4.3.1 Design Principles The drainage system is to be designed in accordance with the requirements of the Institution of Engineers, Australia publication, “Australian Rainfall and Runoff, a guide to flood estimation Volume 1” Current Edition (AR & R). The design shall cater for the major storm event as well as minor storm events. The overall planning and design of the stormwater management system is to be in accordance with the recommendations of, Department of Planning and Local Government, “Water Sensitive Urban Design Technical Manual for the Greater Adelaide Region”, Government of South Australia, Adelaide, 2009 and Institution of Engineers, Australia publication, “Australian Runoff Quality, a guide to water sensitive urban design” 2006.


4.3.2 Site Discharge Limits The RCMB’s SMP is based on an assumed level of development across the specific catchment area. Development requirements are specified in Section 5 of the SMP for specific catchments. Onsite Detention / Retention performance standards for catchments and zones are specified to manage stormwater discharge to a level that can be accommodated by downstream infrastructure. The peak discharge for the post development state needs to be calculated and appropriate mitigation methods used to reduce the post development peak discharge to the site discharge limit. For areas where performance measures are not specified post development conditions will need to match pre-development conditions, unless it can be demonstrated that there will be no adverse impacts on downstream properties or infrastructure. Where a catchment has no outlet, site discharge volumes will also need to be considered.

4.3.3 Water Quality Improvement Prior to development approval a Water Quality Improvement Plan (WQIP) is required. The objective of the WQIP is to present a conceptual design, supported by sufficient design data, to demonstrate that the objectives of the RCMB Development Plan and SMP will be achieved, in relation to Water Quality. The RCMB Development Plan requires stormwater quality to be of a physical, chemical and biological condition equivalent to or better than its pre-developed state. SMP objectives for Water Quality Improvement include;

• Improve the quality of stormwater discharged downstream, with particular emphasis given to nutrients and suspended solids.

• Minimise the quantity of gross pollutants discharged to the River to

improve amenity and safety.

• Intercept and/or separate pollutants at source from land uses and activities having a high potential for pollutant generation.

The WQIP is to Address these objectives. A suggested methodology is that presented in Chapter 3, Department of Planning and Local Government, “Water Sensitive Urban Design Technical Manual for the Greater Adelaide Region”. It should be noted that for small scale developments, not all steps in the process may be required. The development of a WQIP is discussed further in Appendix 1.


4.4 Detailed Design

4.4.1 Hydrological and Hydraulic Calculations Drainage is to be designed to accommodate runoff from lots based on current available zoning information or proposed future zonings, where applicable. The impervious site coverage of residential lots should be based on Table 4.1.

Lot Size (m2)

Impervious Site Area (m2)

Fraction Impervious (%)

<500 90> 500 300 60 800 360 45

1200 450 37.5 1500 500 33

2000 or greater 30

Table 4.1 Impervious Site Area based on Lot Size Road reserves are to be assumed 100% impervious for the pavement area and 50% impervious for verge areas. Rainfall Intensity-Frequency-Duration data for RCMB is included in Appendix 4. For continuous simulation modelling the designer shall seek confirmation from RCMB on the suitability of hydrological data. For rational method calculations the maximum time of concentration used in urban areas should be 20 minutes unless sufficient evidence is provided to justify a greater time. The minimum time of concentration in an urban area used for calculations is to be 5 minutes. For hydraulic analysis, the highest value is to be adopted of the top of the outlet pipe, or the 1 in 100 yr ARI flood level for downstream water surface levels. Where engineering calculations are requested for audit by RCMB they are to be submitted in the following format; For the Minor Drainage system

• Hydrological calculation summary sheets in the form of the example given in Technical Note 6 of AR & R.

• Hydraulic calculation summary sheets in the form of the example given

in Technical Note 9 of AR & R.


Major Drainage system design will normally be undertaken with the aid of computer software programs. It is the designers’ responsibility to provide the RCMB with sufficient information to confirm that the adopted software and assumptions are suitable. As a minimum the following information will need to be provided;

• Name and version of software package. • Full details of the modelling assumptions. • Review of model calibration and sensitivity analysis. • Copy of the model’s “error listing” output file.

4.4.2 Major System Criteria The major storm event is the 1 in 100 year ARI; however in some instances a higher ARI may be required for specific infrastructure. The overland flow path must be contained within reserves a minimum of 10 metres wide, and not enter into private property. The maximum allowable depth of water is 0.2 metres and the maximum velocity x depth product is to be limited to 0.4m2/s. RCMB Development Plan requires 300mm freeboard between the 1 in 100 year ARI flood level and all floor levels. In conjunction with the design of the major drainage system consideration is to be given to ensuring lot levels provide suitable building conditions to achieve this requirement. Where existing overland flow paths exist, developments are to be planned to ensure that the capacity of the existing overland flow path is maintained, and there are no adverse impacts on adjoining properties. RCMB will not permit the use of levees in new developments.

4.4.3 Minor System Criteria The Minor drainage system is to be designed to accommodate the 1 in 5 year ARI. The desirable maximum Inlet Pit depth is 1.5m to facilitate maintenance. Inlet Pits are to be located to satisfy the following;

• Gutter flow widths limited to 2.5m for the 1 in 5 year ARI • Maximum pit spacing 90m where flow widths are not critical. • At the mid-point of allotment frontages to minimise conflict with

service conduits and future driveways. • Upstream of pedestrian paths and kerb ramps. • Swale depths limited to 200mm


Junction pits/Manholes are to be provided:

• At all changes in direction and grade. • At junctions • To enable access for maintenance.

Piped systems are to be designed to satisfy the following;

• Maximum water level to be 150mm below the surface level of pits • Reductions in pipe sizes for downstream pipes are not permitted. • Flow velocities between 0.6m/s and 5m/s. • All pipe sections are to be designed to be free draining.

The design of the minor drainage system should incorporate Water Sensitive Urban Design (WSUD) elements to provide for the deceleration, detention, infiltration and cleansing of stormwater.

4.4.4 Existing Watercourses The Major drainage system should be based on the existing system of natural watercourses. The treatment and rehabilitation of existing watercourses is dependent on their condition, and the site context. The choice of treatment should be based on a review of the site, catchment and receiving waters. Refer to “Australian Runoff Quality” (ARQ) Chapter 12 Urban Waterways for guidance on the selection of appropriate treatment and rehabilitation. For the localised modification of alignment and cross section, and reinforcement at specific locations, the use of ‘soft’ engineered solutions is encouraged. Solutions must be adequately designed and established to ensure long term stability. Designs should consider the use of geotextiles and plantings to provide erosion resistance where possible. Where rock armour is required, partially embedded or grouted natural rocks/boulders should be used, with planting between rocks to soften visual impacts. Where site constraints limit the available space for channel rehabilitation, Gabion Mattresses are to be used. Concrete lining is generally unacceptable. An extended maintenance period (i.e. greater than the minimum 12 month defects liability maintenance period often specified) may be required until the channel has sufficiently stabilised and vegetative cover is well established.


4.4.5 Detention and Retention Detention and retention of stormwater may be required to ensure that runoff does not exceed pre-development flow rates, and volumes. Water Sensitive Urban Design involves retention-based stormwater management. At the subdivision scale this includes stormwater harvesting and reuse, and maintaining soil moisture through infiltration measures incorporated in the drainage system. Detention implies holding of runoff for relatively short periods of time to reduce peak flows. Detention should only be adopted under the following situations;

a) where soil types or topography are unsuited to retention technologies, b) where maximum yield from runoff is desirable with control of peak

flows, c) or to supplement retention strategies when sufficient land area Is not

available. Initial sizing of detention and retention may be undertaken using manual techniques in order to determine the order of magnitude of the storage required. The final sizing however, should be completed with the aid of computer models, and water balance calculations. In addition to local catchment analysis, an assessment should also be made of the impact on a catchment wide basis. Detention and retention storages may have multiple uses such as pollution control, environmental enhancement, aesthetics, as well as hydraulic functions. Large systems must be incorporated in subdivision design, and located in a drainage reserve, or Public Open Space (POS). They may incorporate elements such as sedimentation basins, constructed wetlands, and ponds. Their design is to consider the following provisions;

• Side slopes are to be a maximum of 1 vertical to 6 horizontal • Depth indicators provided indicating maximum depth in the basin • Unfenced landscape areas limited to 100 year ARI ponded depth of

1.2m. • The outlet/inlet grates designed such that any child will be able to crawl

away from the grate under all operating conditions. • A stormwater pollutant trap should be installed upstream.

Detention and retention can be incorporated at the street scale, to minimise the requirements of a major detention/retention structure. They may incorporate elements such as Swales, infiltration devices, and small basins.


Smaller systems may be located in POS, road verges, in medians or traffic islands, or on private land. Their design is to consider the following provisions;

• Detailed assessment of soil types and potential impacts on adjoining structures and infrastructure

• Pre-treatment of stormwater is required prior to entering infiltration devices

• Landscaping should be low maintenance • Emptying time limited to 12 hours for ARI of 1 year or less, 1.5 days

ARI 5 years, 3.5 days ARI 100 years Systems located on Private land will require the registered proprietor(s) of the lot(s) to enter into a covenant pursuant to Section 97A of the Land Title Act 1994, to ensure management of the system is in accordance with the approved report and plans.

4.4.6 Outlet Design Connection to existing RCMB infrastructure should be based on a survey undertaken for the works. Outlets into natural watercourses and open channels are required to incorporate works designed to provide protection from local scouring and undermining of the outlet structure, and include measures to dissipate the outflow velocity. Vegetated swales may be required downstream from piped outlets to achieve water quality improvement targets. Where the outlet is to Public Open Space (POS), the requirements of the Development Plan for POS need to be considered. The opportunity to construct or enhance a natural self sustaining drainage channel (as opposed to enclosed pipe drainage) is encouraged. Where the stormwater discharge is across POS designated for active recreation, piped drainage must be provided for a 1in 1 year ARI event to ensure that the function or the amenity is not diminished.


4.4.7 Residential Allotment Connections A stormwater connection point is required for each allotment in a subdivision. Where allotments grade away from the street frontage rear of allotment (ROA) drainage shall be provided. All ROA drains shall be contained within easements. Such drains shall be designed to accommodate a 1 in 10 year ARI event. ROA stormwater drainage shall also be provided where the allotments back onto reserves. Land divisions in the Country Living Zone may be exempt from requiring ROA drainage provided; site conditions are suitable for on-site disposal, all allotments are greater then 2000 square metres, and any existing dwellings and outbuildings are provided with detention/retention capable of treating and disposing of the 1in 100 year ARI 3 hour duration runoff volume.

4.4.8 Drainage Easements

Easements need to be provided over all drains in any allotments not being a road reserve. Unless otherwise required by RCMB such easements are to be a minimum of 3 metres wide. The width of easements will need to be increased where the easement contains more than one drain, pipes are located deeper than 1.5m, or pipe diameters are greater than 450mm. Where a development relies on an adjoining property to provide back of allotment drainage or an outlet for the proposed drainage system, a Deed of Agreement signed by benefited and burdened parties is required prior to development approval. The Deed of Agreement shall set out the requirements for the creation and piping of the easement, including construction and maintenance activities, and facilitate future access to the drainage network by RCMB.


4.5 Drainage Construction Standards

4.5.1 Stormwater Pipes Stormwater drainage pipes and box culverts shall be of reinforced concrete construction conforming to AS1597 and AS4058 respectively, and in accordance with the following.

• Minimum pipe size of 375mm, rubber ring joint, minimum Class 2 • Minimum box culvert size of 450mm x 300mm • Minimum clear cover over pipes or culverts shall be 600mm in

general or in accordance with the manufacturers’ specification, AS3725 or otherwise approved by RCMB.

Alternative products are to be submitted to RCMB for approval.


4.5.2 Side Entry Pits and Manholes Side entry pits shall be of reinforced concrete construction in accordance with RCMB Typical Detail Drawing No. 2012-5003-001 and 2012-5003-002 located in Appendix 5 Manholes/Junction pits shall be of reinforced concrete construction a minimum of 900 x 900 mm internal dimension, in accordance with RCMB Typical Detail Drawing No. 2012-5011-001 located in Appendix 5 Alternative details are to be shown on construction plans, submitted to RCMB for approval. All pre-cast pits are to be reinforced concrete construction conforming to AS4198. Circular pits shall be a minimum of 1050mm diameter.

4.5.3 Rear of Allotment (ROA) Drainage The minimum diameter of the pipe for ROA drains shall be 150mm and each allotment shall be provided with a minimum 450mm x 450mm grated inlet pit/junction box, located at the lowest corner of each respective allotment. Junction pits shall be provided at all changes in direction and grade. Longitudinal grades shall be a minimum of 1%. ROA drainage shall be constructed from either fibre reinforced concrete drainage pipe, reinforced concrete pipe, or PVC-U pipe which shall conform respectively to the requirements of AS4139, AS4058 and AS1254. Cover shall be a minimum of 0.6 metres in accordance with the requirements of AS3725, or AS2032. Pits shall comply with AS4198, be constructed of concrete, and have tamper proof lids suitable for sustaining expected loads, in accordance with AS3996.


4.5.4 Pipe Connection to Council Infrastructure Prior to backfilling, the works at the connection must be inspected by RCMB Engineering Department for approval Connection to existing stormwater pipe This method can be used where the diameter of the entry pipe is 375mm or less, and the host pipe diameter is at least 3 times larger than the entry pipe diameter. The connection shall be made in the middle third of the host pipe with a 300mm long stub. Reinforcement in the host pipe is to be cut and formed into a collar, and the stub concreted in to the collar, providing 150mm concrete all round the joint, and rendering the inside of the joint. Inspection of the joint by RCMB is required prior to connection of the entry pipe. Connection to existing side entry pit or manhole An assessment of the required pit modification is to be undertaken at the design stage, to ensure hydraulic properties will not be adversely affected. The connection shall only be made through the wall of the pit (not through a corner) and a minimum of 150mm clearance is required between the outside face of the pipe and the pit corner. The pipe must be sealed using cement mortar and finished flush with the internal wall. Where the entry pipe diameter exceeds 200 mm, the pipe must be installed at the pit invert. A minimum 150 mm clear distance is required between the inlet pipes. Other Connections For complex manholes, or for larger diameter entry pipes, new manholes must be constructed.


CHAPTER 5

DESIGN OF EARTHWORKS

5 Earthworks Design

5.1 Earthworks Design Existing site conditions need to be determined to identify any potential risks, and plan future works. In some cases site regrading may be required to provide suitable building conditions for residential development. Developers, consultants, builders etc. should contact RCMB Engineering Department for advice on the requirements of any geotechnical investigations, and building floor levels during the concept and planning stage of proposed new developments.

5.1.1 Geotechnical Investigations Prior to development approval, or as part of detailed design, a geotechnical investigation will be required to identify possible impacts or design issues associated with the development. The investigation should include, as a minimum the details set out below;

• Test pitting over the site to minimum depths of 2.5m to establish and

record the presence of any possible rock or groundwater.

• Classification of all different soils encountered on the site, using visual tactile methods by an experienced technician or engineering geologist and verified if necessary by NATA registered laboratory testing.

• Preparation of a stratigraphical model for the site, including a

description of the underlying geology, and soil formation processes, and identification of any potential slip zones, or areas subject to riverbank collapse.

• Definition of the extent of any fill encountered.

The above information shall form the basis of the design of, drainage, and earthworks, associated with the development. Where potential slip zones or areas of possible river bank collapse are identified development may be restricted, based on the level of risk. It should be noted that for sites that involve filling of clay soils at depths greater than 0.4m and sand soils greater than 0.8m a detailed geotechnical investigation is required, prior to development approval, in accordance with AS1726 – Geotechnical Site Investigations. The report shall be certified by a chartered professional engineer registered with the geomechanics society.


5.1.2 Site Regrading Design Requirements Consideration should be given to future building requirements in the design of site regrading. Generally allowing 300mm from the invert of the gutter to the finished ground level at the building line will accommodate future building requirements. Site regrading details are to be approved in conjunction with submission of other engineering details. Normally the detail will be incorporated in Road Design Plans; however in some cases a separate plan may be required. Where site regrading is proposed details shown on plans shall include;

• the depth of cut and fill, • grades of batters and their finished treatment, • location and details of any earth retaining structures, • volumes of any excess or deficiency in material.

Filling on allotments shall be undertaken in a controlled manner, to enable re-classification of the site to support standard residential footings designed in accordance with AS2870. Batters shall be a maximum grade of 1 vertical to 4 horizontal on private property, or otherwise determined by geotechnical investigations. On public land, batters shall be a maximum of 1 vertical to 6 horizontal to accommodate future maintenance requirements. Retaining walls over 1 metre in height are required to undergo separate development approval unless included in the original development application. No earth retaining structures are permitted in the verge area.


5.1.3 Earthworks Construction The specifications for the works shall provide full details of the proposed earthworks construction procedures. All top soil is to be stripped, stockpiled and re-spread to provide a minimum of 75mm of topsoil to all disturbed areas. All disturbed areas should be stabilised within 14 days of completion of earthworks, and revegetated in accordance with a Soil Erosion and Drainage Management Plan (refer Section 7.4). Where significant earthworks movements are proposed agreement is to be sought with RCMB on suitable haulage routes. The payment of a bond may be required by the contractor/developer where RCMB has some concern about the ability of a haul road to sustain loads without undue damage or maintenance requirements. Where imported fill is to be used the supplier of that material is to provide a written statement of the source of the material and that it is clear of known contaminants.


CHAPTER 6

LANDSCAPE AND OPEN SPACE

6 LANDSCAPING AND OPEN SPACE

6.1 Introduction Landscaping of residential subdivisions includes consideration of the Streetscape, and Public Open Space (POS) elements of a development proposal. The configuration of POS and Streetscape should aim to provide pleasant, functional and accessible open spaces providing a range of physical environments for active and passive recreational opportunities. Design of landscaping should be closely linked with stormwater management to ensure a coordinated approach to managing stormwater quality, and meeting irrigation demand. The Development Act requires contribution for POS either as land or monetary payment or a combination of the two. Where a Developer is proposing to make a monetary payment for Public Open Space, in lieu of land, discussions should be held with the RCMB at the concept plan stage.


6.2 Documentation Requirements Concept plans for Landscaping and Open Space should address;

• the location, type, and size of all proposed public open space (POS)

• functional requirements of all proposed POS • streetscape • site conditions, including existing trees • design intent • Irrigation demand and source

Following RCMB approval of the landscape concept plan design but prior to construction, the Developer shall provide a detailed Landscaping and Open Space Plan incorporating construction details, planting schedules, and a technical specification. The Landscaping and Open Space Plan shall be prepared by a qualified landscape architect and lodged with the RCMB in hard copy and electronically. Typically, Landscape Design Plans will identify:

• Existing elements to be removed / retained • Site grading and drainage • Surface treatments and layout • Planting design • Construction details • Irrigation design • A plant schedule listing the botanical name, the container size and

the quantity/density of planting. Typically, the Technical Specification will comprise:

• Site preparation and demolition • Earthworks and cultivation • Irrigation • Concrete works, and paving • Planting schedule and turf specification • Park and Street Furniture and Fencing • Lighting • Maintenance requirements and Schedules • Landscape Work Schedules.

Approval of RCMB for any variations to the approved plans and specifications during the development stage must be sought by the landscape architect.


6.3 Landscape Design Principles

6.3.1 Landscape Design Principles

Developers will need to consider a range of general design principles when planning streetscapes and open space designs. Reference to “Water Sensitive Urban Design” (WSUD), will assist designers to meet Councils open space objectives. Refer to the Technical Manual, Greater Adelaide Region which is available on Council’s web site.

http://www.murraybridge.sa.gov.au/

Considerations should be given but not limited to;

• The configuration of open space to complement existing vegetation to attract and support fauna native to the local area and to provide a buffer between development and viable ecosystems.

• Integration of streetscapes, parks, reserves and habitat corridors, to provide linear connections within and external to the development.

• Identify opportunities for the retention and/or re-introduction of plant species that are native to the site.

• Establishment of plant material of appropriate structure and species composition.

• Future maintenance of landscape works and ensuring that works are to the appropriate standard, of durable materials and low maintenance design.

• Conservation of irrigation water by using designs appropriate to the climate and utilising water-wise plant selection.

• Maximise opportunities for water re-use where opportunities present themselves.

• Ensuring that the design and development of the site does not increase the rate of surface run-off and that opportunities to improve the quality of surface water before leaving the site are examined.

• Incorporation of on-site detention/retention of stormwater and collection for re-use into the design where opportunities present themselves.

• Increasing the scope of infiltration by minimising sealed surfaces and maximising the use of porous surfaces.

• Utilising appropriate planting to reduce the velocity of stormwater runoff and ensure even flow distribution to avoid erosion.


http://www.murraybridge.sa.gov.au/

• Planned landscapes being complimentary to building structures, and, to maximise the efficiency of buildings, plantings should be established to demonstrate maximum solar gain.

• Plantings being designed to reduce the deleterious effects of wind and other natural climatic events, to provide shade, and promote air circulation to assist the management of the micro climate.

• Using landscape design to create an attractive visual setting for buildings, relative to the scale of the built form.

• Using landscape design to provide an overall character and identity of the streetscape to reinforce the function and character of existing surrounds.

• The orientation of the subdivision design should consider incorporation of frontages to open space to promote natural surveillance and community ownership.

• Design of street lighting and public open space lighting to provide adequate illumination, taking into account the effect of vegetation growth and any other potential obstructions.

6.3.2 Integration with Stormwater Management Best Practice Stormwater Management involves the integration of Public Open Space and Stormwater Management. Natural watercourses should be retained and enhanced where possible, and integrated with linear open space networks to create multiple use corridors. The design of Streetscape offers many opportunities to incorporate Water Sensitive Urban Design Elements to create an attractive and sustainable urban environment.


6.3.3 Existing Trees An “Existing Tree Survey Plan” should accompany the land division plan and be submitted at the time of lodgement. The following information must be clearly shown;

• identification of the species including the botanical name of the tree; • the location of the tree accurately indicated, and; • the height and canopy of the tree and girth of the trunk. • Indicate trees to be retained and removed

Where it is proposed to remove Native Vegetation a proposal may require referral to other agencies for assessment and approval. If necessary, the establishment of a Land Management Agreement protecting significant trees may be required.


6.3.4 Street Trees Street tree planting should be located at the centre of allotments at a rate of one (1) per allotment. Refer to Table 6.1 Suitable Tree Species for RCMB for selection of appropriate species. Alternative Tree Species can be selected in consultation with the RCMB. Trees should have a minimum height of 2 metres at the time of planting, be double staked with 50mm hardwood stakes installed parallel to the road and loose tied. Trees should be planted in a mulched 1 metre diameter bowl with 100mm agricultural drain looped under the root zone to facilitate watering. Street trees are to be planted within the RCMB verge in accordance with RCMB Typical Detail Drawing Numbers 2012-5006-001 to 2012-5006-005 Consideration is to be given to incorporating stormwater harvesting to meet irrigation demand for street trees and water quality improvement targets. RCMB encourages innovative design proposals for stormwater source control, such as diverting stormwater from the Kerb and Gutter for watering Street Trees. The trees shall be maintained in good health by the applicant for a period of 12 months from the date of the issue of a certificate of practical completion. Any dead, diseased and damaged trees shall be replaced during this period.


Street Tree or Reserves Suitable for Reserves Only Local Native Species Euc. Calicogona Brachychiton populensis Euc gracilis Acacia pendula Euc sociali Callitris preissii Euc porosa Euc incrassata Euc odorata Other Native Species Euc. Landsdowneana ‘albopurpurea’ Euc cneorifolia Euc salubrus Euc Campaspe Euc cladacalyx ‘nana’ Euc robusta Euc stricklandi Euc platypus Euc spathulata Euc maculate Euc ethronema Euc diversifolia Euc botryoides Angophera costata Geuirgera parvifolia Melaleuca lanceolata Callistermon viminalis “harkness” Non Native Species Jacaranda mimosifolia Fraxinus ‘Raywood’ Pyrus ussuriensis Koelrutaria paniculate Fraxinus excelsior Melia azedarach (low seeding form) Cupaniopsis anarcdiodes Platanus occidentalis Qurcus robur Pistacio chinensis

Alternative tree may be selected in consultation with The RCMB

Table 6.1 Suitable Tree Species for RCMB


6.3.5 Trees in Reserves Tree planting in reserves shall include a mix of native and selected exotic species to reflect existing plantings in nearby and surrounding areas. For guidance on species selection refer to Table 6.1 Suitable Tree Species for RCMB. The following should also be taken in to consideration;

• Existing trees on the site • Soil stabilisation needs • Accessible shade • Ease of future maintenance • Proximity of fences and pathways (trees should not be planted

closer to fences that abuts private property than their mature height). • Bushfire risk minimisation • General aesthetic quality

Reserve areas should be designed via consultation with RCMB’s Environmental Officer.

6.3.6 Grassing All grassed areas shall:

• Be provided a minimum depth of 150mm of suitable topsoil to provide a satisfactory growing medium.

• At the end of the maintenance period be fully established with

Kikuyu. If seeding is used a mixture of 95% Rye and 5% Kikuyu is recommended.

6.3.7 Traffic Islands and Roundabouts Proposals for landscaping of traffic islands and roundabouts shall be submitted to RCMB for consideration. Proposals need to demonstrate minimal maintenance requirements, and will generally only be permitted as part of a Stormwater Quality Improvement Device.


6.3.8 Fencing Discussion with RCMB on specific requirements is required. Generally reserves shall be fenced with 1800mm capped Colourbond fencing with galvanised posts and rails facing into the adjacent allotment. Alternate fencing may be selected in consultation with the RCMB Where a reserve incorporates a children’s playground, full or part fencing may be appropriate, e.g. a half fence closer to a road or car park to define or partly separate the playground. In general, playgrounds should be considered for fencing if:

• The playground is located close to a busy road and there is no fence around the reserve

• The playground is close to a busy a car park • The playground is near a permanent or potential water body

(alternatively there could be a barrier around the water body) • There may be a need to separate the playground from other

activities, such as an active sports field • There is a demand for a dedicated enclosure for children and

families, e.g. a playground for toddlers where fencing and the safety of children is a desired feature.


6.3.9 Irrigation An Irrigation Management Plan for the reserves is required by RCMB prior to installation. The plan needs to encompass best water management practices and it should incorporate the following features;

• Irrigation demand is to be met by alternative water sources, such as recycled stormwater, River Murray Irrigation, or reclaimed effluent, supplemented by a SA Water supply.

• All licensing and approvals required from other authorities are to be

submitted with detailed design plans • Where demand is to be met with River Murray Irrigation Water

arrangements are to be made for purchase of water licences in the name of RCMB, and integration with RCMB existing irrigation main network.

• Species selection is to minimise irrigation requirements

The following requirements need to be addressed

• An appropriately sized service connection and water meter are required to all open spaces and reserves with a suitable backflow prevention device fitted to comply with AS 3500.1 section 7and SA Water requirements.

• valves, fittings and backflow prevention devices suitable for

automatic operation and, capable of utilising reclaimed water (class A) and mains water.

• The installation of an irrigation system to all landscaped traffic

islands and roundabouts is mandatory Irrigation systems are to be installed to RCMB satisfaction in accordance with RCMB’s Irrigation Design and Installation Standards.


6.3.10 Furniture Park furniture including seats, tables, litter bins, bike racks, drinking fountains etc will be of a type and manufacture approved by RCMB. Seats should have arm rests to assist people who are frail and have difficulty lowering and raising themselves. Tables should be of a design that is accessible and inclusive, with greater capacity at the ends for forward approach by a person using a mobility aid. Materials are to be durable and require minimal maintenance for their intended life. The use of timber elements is not encouraged due to ongoing maintenance requirements.

6.3.11 Paths All facilities in POS should be provided with a continuous accessible path of travel to facilitate independent, safe and equitable access to ensure compliance with RCMB Disability Discrimination Act Policy. Paths within reserves should create pedestrian and/or bicycle links to existing paths in the vicinity of the development. Refer to Section 3.4 for detailed design requirements. For reserve areas it should be noted that 600mm on both sides of the footpath should be at the same grade and flush with the path.

6.3.12 Lighting Public lighting may be required in reserves where paths or access to other structures are features of the park. For more information regarding Public Lighting see section 3.6.4.

6.3.13 Entrance Statements All entry statements and walls require separate Development Approval. Installation shall only occur once construction and landscaping details have been approved in accordance with conditions set out in a development approval.


CHAPTER 7

SITE MANAGEMENT

7 SITE MANAGEMENT

7.1 Introduction The Developer and contractors are responsible for ensuring compliance with the Environment Protection Act 1993, and its various policies, and the requirements of any other relevant statute, by-law, standard or policies relating to Occupational Health Safety & Welfare (OHS & W), Environmental Protection, and protection of the River Murray under the River Murray Act.

7.2 Construction Management Plan A Construction Management Plan (CMP) prepared specifically for the works shall be provided to Council. The CMP is to address in detail how the site will be managed to minimise disruption to adjoining properties and demonstrate how compliance with the Environmental Protection Act will be achieved. The CMP shall detail OHS&W, (including Risk Assessments & Job Safety Analysis), traffic management, and any other matters that are relevant to the site and maintaining amenity in adjoining areas. It should also consider the broader objectives of material recycling, waste management and environmental initiatives, including water conservation.

7.3 Soil Erosion and Drainage Management Plan A Soil Erosion and Drainage Management Plan (SEDMP) needs to be submitted as part of engineering design plans. The plan should include a site layout together with a written procedure and implementation plan. The SEDMP should be prepared in accordance with the Environment Protection Agency Code of Practice 'Stormwater Pollution Prevention Code of Practice for the Building and Construction Industry'. Environment Protection Authority, March 1999, and cover all stages of works including maintenance of the site up to the end of the defects liability period. The SEDMP should also clearly indicate areas that are not to be disturbed. These areas are to be clearly marked on site to ensure construction activities do not affect areas to an extent greater than is necessary. Where plant pest species are present on the site the SEDMP should also address management and control of its' spread.


7.4 Existing Trees All existing trees to be retained shall be protected during construction activities. The following tree protection measures shall be undertaken;

• All construction drawings including the landscape design plan, earthworks, and drainage and service drawings shall show the trees to be retained and their protection zones.

• Each tree is to be physically protected by providing a fence defining

the Tree Protection Zone and shall remain in place until all works are completed.

• There is to be no storage of materials or machinery or site

office/sheds, nor is cement to be mixed or chemicals spilt/disposed of in the area, soil levels altered or excavations undertaken, or stockpiling of soil or rubble within the tree protection zone.

The applicant shall contact RCMB to arrange a site inspection to verify that tree protection measures have been installed prior to commencement of excavation. In some instances a Land Management Agreement may apply to the protection of Existing trees. The Developer shall ensure that the provisions of the Land Management Agreement in respect to trees are complied with.

7.5 Working Hours The contractor is required to comply with relevant policies under the Environment Protection Act. Within the area of RCMB it is recommended that construction activities on the development site shall only be carried out between the following hours;

• Monday to Saturday - 7am to 5pm, • Sunday and Public Holidays - no work should be undertaken other

than necessary watering for dust control. RCMB Engineering Department and affected residents should be notified if works are planned outside of these times.

7.6 Site Access Where more than one street abuts the development site RCMB will nominate the location and street from which access to the site is obtained. Developers are required to obtain RCMB’s consent for the location of working access points to the site. Consent is to be obtained through the RCMB Engineering Department.


CHAPTER 8

QUALITY ASSURANCE REQUIREMENTS

8 Quality Assurance Requirements

8.1 Submission of Plans All engineering and landscape drawings or plans are to be presented to RCMB’s engineering department for approval. Each set of plans should be accompanied by a Transmittal Record and a statement on compliance with the requirements of this document. All aspects of the design which do not meet requirements or tolerances set out in this document should be noted. Revised or amended drawings are to note and ‘revision cloud’ the specific amendment on the drawing plan and be submitted to RCMB with an updated Document Register. RCMB shall be provided with 2 A1 Copies, pdf files, and a Document Register for all drawings issued for construction.

8.2 Minimum Drafting Requirements Design plans should be definitive and clearly set out so as to present the design concepts in such a way that the project can be understood, specified for construction and satisfactorily built. Drawings are to be on A1 size sheets, and shall not rely on colour printing or colour wash to impart information, and be suitable for black and white copying and photo reduction to A3 paper size without loss of clarity. All design plans should be clearly numbered, including revisions by the designer with separate sheets numbered as part of a set. All drawing sheets should specify in the title block along the bottom right-hand corner the development proposal’s full site address and DAC File Number (e.g. 415/D000/09).

8.3 Inspection and Testing An Inspection and Testing Plan shall be included with the construction schedule submitted prior to commencement of works. The inspection and testing plan needs to include Hold Points and specify the timing and frequency of testing required.


8.3.1 Hold Points Works are to be held, and the RCMB Engineering Department notified for the purpose of inspection, at the following stages Prior to commencement of earthworks:

• At completion of preservation measures for trees, vegetation or heritage sites.

• At completion of installation of erosion and sediment control measures.

During the course of earthworks:

• After clearing and preparation of subgrade. • At completion of earthworks prior to re-establishment of finished lots,

verge areas, and landscaped areas.

During the course of road and drainage construction:

• After preparation of the base-course, for proof rolling, prior to sealing.

• After the construction of drains and drain structures, prior to the

backfilling of trenches.

• After connection to the existing RCMB drainage system (where applicable) prior to backfilling.

All inspections require at least 24 hours notification in writing to the RCMB officer nominated in the Pre-Start Meeting.

8.3.2 Testing and Certification Requirements This list of testing requirements is not exhaustive and shall be the minimum requirements to verify compliance with RCMB specifications. Site Inspection Records Pavement Levels – A site inspection report verified by the Principal Consulting Engineer shall be submitted to verify the finished levels of each layer of pavement. Levels shall be taken at 10m intervals on both sides of Roads at the location of Face of Kerb, and Road Centreline. Inspection reports shall be submitted to RCMB prior to the next stage of works proceeding.


Compaction Tests All compaction testing shall be carried out by an approved National Accredited Testing Authority (NATA) registered testing laboratory. Certified test results shall be submitted to RCMB prior to the next stage of works proceeding. All tests must pass: Road Pavements - Two tests per thousand square metres in each layer (subgrade, subbase, and basecourse) with a minimum of two tests per layer. The RCMB may specify additional testing requirements at specified locations if the quality of workmanship is suspected of not being satisfactory. Compaction test results shall be submitted prior to commencement of the next pavement layer. Trenches in Roads – Compaction tests shall be undertaken at one test per each layer for each material every 30 metres of trenching. One test per trench for each service trench to each property. Compaction test results shall be submitted prior to commencement of the next stage of works. Proof Rolling RCMB Engineering Staff shall be present for proof rolling of subgrade, and basecourse.

Appendix 2. Inspection shall be carried out at the end of the defects liability period.

8.4 Tolerances on finished works Infrastructure will only be accepted when it meets the tolerances listed below. The tolerances represent an acceptable level of service for the associated infrastructure. All other tolerances shall be as set out in the specification. Works that do not conform to the tolerances will not be accepted by RCMB. Kerb – 0 or -5mm to adjacent seal Seal finish - No more than 5mm departure from 3m straight edge. Dense even surface. Footpaths & Shared paths– No more than 5mm departure from 3m straight edge. Verges – No more than plus or minus 20mm in any location Batter slopes – No point shall vary from batter slope line by more than plus or minus 150mm. Stormwater Pipes – Within 10mm of design invert levels and within 25mm of the correct alignment. Gully Pits – Tolerance on location within 20mm and finished level within 0 or minus 5mm of adjacent kerb/pavement level.

8.5 Retention Monies & Bonding Arrangements There are three bonding arrangements associated with the land division process. Local Government Bond - A bond required prior to commencement of construction work to cover any damage that may be caused to RCMB infrastructure. Early Section 51 clearance Bond – A developer may wish to apply for early clearance by bonding outstanding works. Retention Monies – A percentage of the contract price paid to RCMB at the completion of works for rectification of defects in the work during the maintenance period. Bonding arrangements shall be provided in the form of a Bank Guarantee undertaken with a financial institution to Council’s satisfaction, or cash. All bonding arrangements shall be finalized prior to Section 51 clearance.


Local Government Bond The bond is held by RCMB until the completion of construction activities. At the end of the construction period any damage shall be remedied by the developer, or the cost of the repairs determined by RCMB, and the amount being deducted from the bond, and the remaining credit returned to the developer. The specifics of the agreement will be set out in accordance with the requirements of section 254A of the Local Government Act.

Early Section 51 clearance Bond RCMB will only allow the developer to enter in to a bonding arrangement with RCMB for the completion of works, when construction has been substantially completed (all services and kerb and gutter installed). Bonding amounts shall be generally based on sums included in the contract, as agreed by RCMB plus twenty (20) percent. Where a contract sum is not available for the component of work, the rates shall be as determined by RCMB based on current construction costs plus twenty (20) percent. Retention Monies Construction work will be guaranteed for a minimum period of twelve (12) months from the date of Practical Completion. The guarantee shall be in the form of a legally binding agreement between RCMB and the developer. The agreement shall set out the commencement date, length of guarantee period and retention monies for specific infrastructure components such as roads, stormwater, footpaths, and landscaping, performance criteria, and dispute resolution procedures. The value of the retention monies shall represent between five (5) and ten (10) percent of the total Contract price, based on the risk of failure, and the likely costs of remediation.


Appendix 1

Water Quality Improvement Plans

APPENDIX 1 - Water Quality Improvement Plans Water Quality Improvement Plans The RCMB Development Plan requires that all sites shall incorporate some level of water quality improvement. Applicants will be required to demonstrate how each stage of the treatment train will be addressed. It is recommended that the Water Sensitive Urban Design Technical Manual for the Greater Adelaide Region, Government of South Australia, 2009, be used for guidance on design. A simplified approach is considered sufficient for small development proposals, on sites smaller than 5000 square metres, up to a maximum of 8 future lots. For larger sites developers will need to undertake water quality modelling to assess the effectiveness of the proposed treatment train Site area less than 5000 square metres, and up to a maximum of 8 lots The opportunities for incorporating WSUD are limited at this scale. To satisfy water quality improvement targets a site will generally need to incorporate vegetated areas or a filtration system to cleanse stormwater runoff from roads and driveways. This can either be done through the use of conveyance measures such as replacing conventional kerb and guttering with swale drains, or incorporating filtration systems prior to discharge. To demonstrate compliance with the RCMB development plan the design and layout of drainage infrastructure shall satisfy the following; Existing dwellings are to be retrofitted with a 2KL rainwater tank for every 100m2 of roof area. Overflows are to be directed to a soakage trench or infiltration device. Where new access way or road construction is required; Road and access way Drainage shall be conveyed using grassed swales designed to treat the 1 in 3 month ARI peak flow rate, with an allowance for runoff from residential driveways. Or Road and access way Drainage shall be directed through a filtration system, sized to treat the volume of a 1 in 3 month event for the contributing sub-catchment area, based on a design storm duration equal to 2 times the sub-catchment time of concentration.

Rural City of Murray Bridge, V 1.0 i

Filtration systems include bio-retention systems, rain gardens, and infiltration systems. The one in three month event shall be taken as half the 1 in 1 yr ARI average rainfall intensity. The objective of this approach is to promote the use of the road reserve for detention and infiltration, by incorporating treatments such as landscaped basins, swales, and bio-retention. Community title developments should locate the treatment measures on communal land adjacent the access driveway to provide for ease of access for maintenance purposes. Site area greater than 5000 square metres, and land divisions of more than 8 lots Land division of this size will normally present sufficient opportunities to develop a full treatment train approach to water quality improvement. Water Sensitive Urban Design Technical Manual for the Greater Adelaide Region, Government of South Australia, 2009, outlines the process of developing a WSUD plan for a site. Table 3.1 provides a scoring system to determine the potential risk to the effective implementation of Water Sensitive Urban Design (WSUD) on a subject site. It is suggested that this table be completed and included in the WQIP. Table 3.2 can be used as a guide for the indicative information requirements that need to be included in the WQIP. Objectives should be drawn from RCMB Development Plan, SMP, and IWRMP. Default targets developed by the EPA and Murray Darling Natural Resource Management Board are listed in Table 1.

Pollutant Description Retention Criteria

Litter/gross pollutants

Paper, plastic, metals, glass and organic materials

Retention of litter greater than 50mm for flows up to the 3 month ARI peak flow

Total Suspended Solids

80% reduction of average annual pollutant load

Coarse Sediment Coarse sand (=0.5mm) 80% of load for particles 0.5mm or less

Fine Particles Fine Sand (=0.05mm) 50% of the load for particles 0.1mm diameter or less

Nutrients Total Phosphorus and Total Nitrogen

45% retention of the load for each

Hydrocarbons, Motor Spirit, Oil and Grease

Anthropogenic hydrocarbons that can be emulsified

No visible oils for flows up to the 3 month ARI peak flow

Table 1: Pollutant Retention Criteria for Stormwater Treatment Train

Rural City of Murray Bridge, V 1.0 ii

Hydrocarbon and Gross Pollutant targets apply to land uses where there is a significant export of litter and oil and grease and generally only apply to commercial and industrial areas. To demonstrate compliance with these targets stormwater quality modelling needs to be undertaken.

Appendix 2

CCTV Pipe Surveys

APPENDIX 2 – CCTV Pipe Surveys Pipe surveys are required to determine the pipe condition at the end of the defects liability period, prior to acceptance by RCMB. The Applicant must submit both a hardcopy report and a video display of the closed circuit television camera (CCTV) inspection. The CCTV inspection report and video must be reviewed by the supervising engineer prior to submission of the report and video to Council. For any defects identified remedial measures shall be recommended by a suitably qualified engineer and submitted to RCMB for approval. Once the remedial measures have been completed, a follow up survey is required to demonstrate that they have been carried out to Council’s satisfaction. All costs to undertake the above process will be borne by the Applicant. Any person entering a Council stormwater drain must fulfil requirements of the current Workplace Health and Safety Act; such as confined space training. Survey Protocol The CCTV pipe survey must provide a CD/DVD quality video report achieved by using the Wincam CCTV data capture and asset management software or similar standard of presentation, allowing easy interpretation of the pipe survey and report. If longitudinal cracks are observed at the obvert of the pipe, particular attention should be paid to the invert and the 3 o’clock and 9 o’clock positions for evidence of crushing. All cracks should be closely monitored whilst the camera is in motion. All joints should be fully scanned (over 360°) whilst the camera is stationary. The video display and hardcopy report should show all the faults, features and connections in the line. A typical example given below illustrates the reporting format required; Pit 18 → Pit 17 (upstream), 375 mm RCP. Distance:

• 0.0 m - start survey, joint satisfactory • 2.4m to 25m – no defects and all joints satisfactory • 26.9 m - minor longitudinal crack, position 12 o’clock, minor tree roots

up to 25%. • 45.0m – survey completed.

APPENDIX 3

Meeting Checklists

Pre-Start Meeting Process

Only works that have been ‘Approved’ by the RCMB can be submitted for the Pre-Start process and meeting. These works must incorporate all aspects of the Planning Approval including any public consultation (which may be required) and any correspondence from concurrence agencies. This document is in three parts and must be attached to all supporting documentation. The shaded areas identified in parts 1and 2 and are to be completed by the applicant and submitted to RCMB to initiate the Pre-Start process. Parts 2 and 3 will be used by the RCMB during the site meeting. Failure to provide the required information in sufficient detail and in a timely manner may delay the RCMB’s ability to hold a Pre-Start meeting and permit works to proceed.

Accuracy of Submission

i. RCMB’s examination of documents should not be taken to mean that the documents have been checked in detail and RCMB takes no responsibility for their accuracy. If during construction, inadequacies of the design are discovered, it is the responsibility of the Principal Consulting Engineer to resubmit amended plans to RCMB for approval and rectify works accordingly.

ii. Notwithstanding any approval given to engineering documents,

where a discrepancy occurs between these documents and RCMB’s standards, then RCMB’s standards shall apply. All works must be performed in accordance with RCMB standards and relevant laws and guidelines.

iii. If in fact there are errors, omissions or insufficient detail on the plans

for the purpose of construction, these deficiencies shall be made good during construction and RCMB reserves the right to withhold approval of construction until such deficiencies are made good to its satisfaction.
