1 INTRODUCTION

The site of the proposed Alexandra Drive development is located on 54.92ha of land approximately 1km west of the Nambucca, in the Nambucca Local Government area.

The land is situated on the northern corner of on either side of Alexandra drive and borders two creeks, Swampy creek and Bellwood creek.

Figure 1.1, area to be enclosed by the proposed development.

The land is to be sub divided for residential living with all the land being subdivided except for the various reserve areas proposed. The site is planned to be developed over several stages.

The following document outlines the construction, traffic and pedestrian management measures to be adopted by the Head Contractor for Stage 1. The actions recommended will provide for safe ingress and egress from the site whilst minimising and mitigating potential impacts drivers using Alexandra Drive. A particular focus is on traffic and pedestrian management for the construction of Stage 1 of the proposed development.

This document also identifies a range of sound construction practices to mitigate environmental risks during Stage 1 works. These will be addressed by the Stage 1 Construction Environmental Management Plan (CEMP) to be undertaken by the Head Contractor. The list of issues is based upon the NSW Department of Housing’s standard, which is a benchmark document for this type of construction in NSW.

The traffic, construction and environmental management issues identified and the recommended actions will be similar for ongoing stages of the works and the management process outlined in this section will be used as a template for future stages of work, to be implemented at the development progresses.

Figure 2.1, Lot Layout..

The main development is located west of the Pacific Highway occupies both sides of Alexandra Drive. Access during construction, to the site is proposed from one point:

Alexandra Drive –the eastern leg of the roundabout at the entrance to the undeveloped land.

The type of construction operations which will be undertaken onsite will include:

Bulk Earthworks

Road and drainage works

Service utility installation

Residential construction

Landscape works.

The type of vehicles which will be operating on the site and requiring access to the site include, tip trucks, excavators, backhoes, graders, water carts, concrete mixers and pumps, rollers etc.



January 2012

3 OBJECTIVES

The Environmental and Construction Management Plan will be used to define the traffic and environmental management measures to be adopted by the Head Contractor for the Stage 1 works on the site. These measures are to be implemented to:

provide a safe environment for all surrounding residents, road users and workers onsite

provide protection to workers, visitors and the general public from traffic and environmental hazards that may arise as a result of the construction activity

minimise the disruption, congestion and delays to all road users

Ensure network performance is maintained at an acceptable level throughout the term of the work.

eliminate or mitigate risks of damage or degradation to the environment through sound construction management practices

To achieve these objectives, the Construction Management Plan will:

ensure that the road capacity is sufficient to accommodate vehicle traffic volumes and disruptions are minimised

ensure that appropriate warning and information signs are installed

ensure that all needs of road users, motorists, pedestrians, cyclists, public transport passengers and people with disabilities are accommodated

provide for work activities to be undertaken sequentially to reduce the adverse impacts of the work

provide for safety procedures to enable work personnel to enter and leave the work area in a safe manner

Identify potential environmental risks from standard construction activities and define sound construction practices to be adopted by the Head Contractor to eliminate or mitigate these risks.



January 2012

4 ENVIRONMENTAL MANAGEMENT PLAN

4.1 Monitoring and Measurement

4.1.1 Site Inspections and Record Keeping The operation will monitored to ensure that it proceeds as explained in the Head Contractors CMP. Daily inspections before construction will ensure are concurrent with those specified in the plan and that there are no potential hazards. Any adverse impacts will be recorded and immediately dealt with if they arise.

4.1.2 Public Feedback The head contractor will be obligated to develop a constructive relationship with those in the immediate vicinity and community of the development.

A forum for consultation with the public will be set up where feedback will be encouraged and updates on the development will be posted to keep residents up to date with activities on site. A letter box drop to inform local residents of construction timing, work duration and what works are occurring at what times, changes to these times should also be notified to residents.

Any suggestions or complaints concerning the construction traffic will be processed, recorded and appropriate action taken where necessary. Public will be notified as to how the issue has been dealt with.

4.1.3 Site Induction Anyone entering the site will be required to undergo a site induction. The induction will include access routes, parking, deliveries, emergency procedures, OH & S and standard environmental requirements and regulations.



January 2012

5 IMPLEMENTATION OF MANAGEMENT PLAN

5.1 INTRODUCTION Projects of this size are typically required to prepare an Environmental Management plan prior to Construction.

The Environmental Management Plan construction site specific plan which is used to ensure that

best practice environmental management procedures are applied to the construction practices and the maintenance and environmental phases of each stage of development

The findings of the site’s environmental assessment are adhered to and the conditions of approval are followed to the letter

On site activities comply with all current environmental legislation

The environmental risks associated with the project are properly identified and managed.

An Environmental Management Plan will be prepared for the development prior to construction. This will be prepared with reference to the NSW Government’s “Guideline for Preparation of Environmental Management Plans” (DIPNR 2004). Many issues considered as part of the Environmental Management Plan are common on such developments. The NSW Department of Housing Guideline EMP Checklist (2000), can be used as a guide as many of these issues are identified. The checklist is summarised in Appendix B. The following sections outline the proposed control measures for a range of issues that may arise during construction, operation and maintenance stages of development; and proposes the implementation of these control measures to each stage of development. It should be noted that the application of these control measures at each stage of development will be assessed on a case-by-case basis as development progresses. The diagram shown below in [Section 5.2.2] (including vehicle access routes and control measures) will be used as a template for the layout of future stages of development.

5.2 TRAFFIC MANAGEMENT

5.2.1 GENERAL Traffic Management Plans will be required to be prepared by the Head Contractor at each stage of construction. The recommendations contained in this document will be adopted for the Stage A1 and A2 plan of construction.

Where traffic management measures are required on RTA controlled roads (such as Pacific Highway), the design is to be certified by an RTA accredited professional.

5.2.2 SITE ACCESS CONDITIONS Site access during the construction of Stage A1 and A2 is proposed from Alexandra Drive. Heavy vehicle and delivery movements via a main temporary access, will be only access point to site. Alexandra Drive is a local two lane rural road of variable width; it has a 50km/h speed; the grade leading up the intersection is gentle with the rest if the road traversing downhill towards the development. Stage access routes are shown below in Figure 5.1.

Figure 5.1 - Site Access Routes for Stage A1 and A2

STAGE A1 and A2

STAGE 1 SITE ACCESS



January 2012

5.2.3 WORKING HOURS The environmental assessment states that all construction activities including materials delivery is restricted to the following hours:

7:00am – 6:00pm, Monday to Friday

8:00am – 1:00pm, Saturday

No work on Sunday or Public Holidays

Any construction work outside the above hours can only be approved by appropriate authorities prior to work commencing after appropriate consultation with affected residents.

5.2.4 PEDESTRIANS Pedestrian amenity within the vicinity of the site will be protected through signage, barricades and webbing. There will be no public pedestrian route through the construction site. Pedestrian routes in close proximity or within area of site works will be diverted to safely cater for the needs of pedestrians. Where construction works interrupt existing pedestrian routes, temporary pedestrian access in close proximity to the existing arrangements will be provided with suitable signage. Pedestrian movements will be subject to continuous review and will be adjusted when necessary. Pedestrian movements within the construction site will be subject to standard construction OH&S practices.

5.2.5 EMERGENCY VEHICLE ACCESS Emergency vehicle access will be available through the main access point. The access for police and emergency services will remain open during construction working hours to minimise response times. Liaison will be maintained with the police and emergency services agencies throughout the construction period and a 24 hour contact will be made available for out of hour’s emergencies and access.

5.2.6 POTENTIAL IMPACT OF CONSTRUCTION TRAFFIC The potential impact of vehicles associated with the construction has been investigated so as to enable the implementation of the appropriate traffic management measures.

5.2.7 EXISTING TRAFFIC FLOWS The existing peak hour traffic movements are taken from a Traffic Counting Study undertaken in February 2009. The full results of the traffic assessment are given in Annexure D.

Alexandra Drive North-South

Morning peak 61 vehicles/hour

Evening peak 56 vehicles/hour



January 2012

5.2.8 CONSTRUCTION TRAFFIC IMPACT

ALEXANDRA DRIVE The number of workers onsite at any one time is estimated at between 10-15 persons with the maximum no more than 15. Assuming that the workers arrive by private vehicles and each vehicle transports two persons it can be assumed that up to 8 vehicles per day will be present. A low flow of vehicles visiting and exiting the site will occur throughout the day. These extra vehicles will have limited impact on Alexandra Drive as these vehicles will only be using a very small section of the road (100m) and will not interfere with other resident’s properties or other traffic. This has been confirmed by the Traffic Assessment report given in Annexure D. Road safety and noise issues will need to be addressed to ensure minimal discomfort and delay is caused on residents. It is considered that this can be addresses through community consultation, education and sign postage.

The following measures will be adopted

Site induction will include procedures for accessing the site from Alexandra Drive

Ongoing staff meetings will reinforce the need for care when using Alexandra Drive.

Signage will be placed at the access and at Alexandra Drive warning site employees that they must observe speed limits and to reduce noise.

Car pooling will be encouraged to reduce vehicle numbers.

Opportunities to stagger arrival and departure times will be investigated to minimise effect on pedestrians and school children during Bus drop off times

Cars will access the site via a maintained gravel road. A wash down area will not be required however a cattle grid may be used to ensure no dirt exits the site.

Corrective action To be detailed at the time



January 2012

5.4 CONSTRUCTION PHASE

5.4.1 GENERAL Prior to construction in any stage, detailed Environmental Management Plans will be prepared, based on the requirements of DIPNR (2004) and submitted to council. The estate will developed in several stages to minimise the potential for soil erosion and water pollution and places less strain on the immediate ecosystem. This would also mean less impact on residents surrounding the development. By developing in stages it enables the environment to be progressively rehabilitated as the development proceeds. Wherever possible the site will remain undisturbed until construction of that area or stage is to take place. Prior to commencement of bulk earthworks, temporary sediment and erosion control measures should be installed in accordance with the management plan and the Institution of Engineers Soil Erosion and Sediment Control Guidelines. All the runoff from disturbed areas is to be managed by the installation of silt fences and contour drains. Runoff should be dispersed evenly and concentrated flows should be limited. Runoff from undisturbed area should be diverted around disturbed areas wherever practical to minimise erosion of construction site. Control measures such as sediment ponds, silt fences, contour drains should be installed and maintained in accordance with the recommendations contained in the “Soil Erosion and Sediment Control Engineering Guidelines for Queensland Construction Sites” June 1996, by the institution of engineers Australia (Queensland Division). Sediment and erosion control must remain in place throughout the entire construction process until final landscaping is finished and established. Additional sediment and erosion control plans are outlined in Appendix C The soil on site has been earmarked as being low fertility soil, however nutrient transport from site should be minimised with appropriate measures.



January 2012

5.4.2 DUST MANAGEMENT Person Responsible: Contractor’s Site Manager Issue Minimisation of movement of dust offsite

Operational policy To achieve acceptable air quality standards through the control of the movement of dust offsite from site works.

Performance The target level for complaints by nearby residents is no criteria more than one in any seven day period. Ambient air quality should not

deteriorate by more than 30% over a period of seven consecutive days. Dust deposition at any nearby residence should not exceed 100mg/m2/day.

Implementation The minimisation of the movement of dust offsite will be strategy achieved through the following onsite practices:

1. All permanent bunds and reshaped areas will be revegetated within 10 days after completion of earthworks (including excavation and backfilling of services trenches). 2. Stockpiling onsite will be minimised where possible. 3. An on-site water cart will be available at all times. The site will be watered daily and additional watering will be conducted during high-risk times such as high winds and low rainfall and after receipt of complaints. 4. All dust creating activities to cease if wind speed exceeds 10m/sec. 5. Contractors staff to be trained to implement dust minimisation measures.

Monitoring Daily inspections will be carried out to verify that dust mitigation measures are being implemented. Dust monitoring will be conducted upon receipt of complaints by residents. If dust monitoring is to take place, the following will occur: • Temporary dust deposition gauges will monitor the movement of dust offsite at the nearest residences adjacent to the proposed stages and within the predominant wind directions . • Monitoring will be undertaken in accordance with AS 3580.10.1 (1991).

Auditing Management to examine the complaints register weekly and review corrective action taken

Reporting The contractor to notify EPA of a possible environmental nuisance on receipt of 3 or more dust complaints in any 24 hour period. Reports will be provided to Nambucca Shire Council upon request. Complaints by residents are to be recorded in a Complaints Register and notified to Nambucca Shire Council.

Identification of incident or failure

Any dust-related complaints by residents will indicate a failure of the dust control measures.

Corrective Action Locate the source of the dust and implement the following measures: • apply water sprays to vegetation • cover or water exposed areas • if dust persists, cease the dust creating activities All dust complaints to be addressed in consultation with Council Officers.

Wash out in an area where water cannot enter waterways, stormwater drains, footpaths or roads, preferably up slope from a sediment control device

Transfer as much paint as possible back to the tin Spin brushes and roller sleeves in a waste paint drum Irrigate a flat grassy area with diluted wash out water, ensuring that it does


For solvent based paints, return solvent to a solvent recycling depot Dispose of solid paint waste with other solid waste Determine if lead is present in surfaces to be painted Seal the area with plastic sheeting to prevent escape of dust To prevent lead fumes, do not use open flame torches on lead paint Use a high efficiency particulate air (HEPA) vacuum cleaner to clean up lead

dust

Wash surfaces with a small amount of high phosphate detergent Minimise paints and chemicals on site by ordering the minimum quantities Store paints and chemicals in a bunded area where they can be contained if

spills occur

Keep Material Safety Data Sheets (MSDSs) on site at all times Keep clearly marked booms and/or absorbent material on site to contain

spills if they occur



January 2012

Other: If a spill occurs, stop the source, contain it, clean up in accordance with the

MSDSs and notify relevant authorities

6 BUILDING SERVICES


Fill in service trenches as soon as work is completed to minimise erosion Cover service trenches with plastic sheeting or another suitable cover if

filling cannot be immediately completed

Connect guttering and downpipes to the stormwater system as soon as the roof is completed

Other: Ensure there are no cross connections made between the stormwater and public sewerage system

7 LANDSCAPING


Once no longer required, reinstate ground level around the works, fill spoon drains and sediment basins, level blanks and remove surplus soil

Complete landscaping and revegetation as soon as possible following building activities

Ensure sediment control measures are in place until all vegetation is established

Regularly check all sediment control structures to ensure they are working effectively

Ensure that no disturbance of the nature strip occurs between the site and the roadway

Do not locate stockpiles within 2 metres of hazard areas such as spoon drains or areas of high flow

Ensure stockpiles and open dusty areas are damped down as required Cover stockpiles as needed to minimise dust Ensure that soils and fill used in landscaping area are free from weeds and

weed seeds

Ensure appropriate trees are chosen for the site and location relative to building and services considering their eventual height and root system
