1 Purpose

The purpose of this chapter is to guide the development of the Worrigee area, to provide for a range of housing types and compatible developments within the residential environment. Advisory Note: In addition to the provisions outlined in this Chapter,

you must refer to the supporting map: Chapter N10 Map 1.

2 Application

This chapter applies to land at Worrigee as shown in Figure 1 below.

Figure 1: Subject Land Map

3 Context

This section provides information and development controls needed to prepare applications for development in the Worrigee area. As part of any subdivision application, you must demonstrate how your development addresses the supporting map.

4 Objectives

The objectives are to: i) Identify community and recreational facilities to meet the needs of the local community. ii) Ensure residential amenity is maintained at a high level.

5 Controls

5.1 Topography, Drainage and Vegetation

The topography of the area, as shown in Figure 2 below, is undulating ranging from 4 45m AHD. The two highest points are at Browns Hill on the highway and in the south, Terara Road generally follows the main north-south ridge that divides the plan area into two major catchments. The western side drains into the floodway (and eventually Nowra Creek) south of Hillcrest Avenue. The majority of the area south of Hillcrest drains directly to the north into the rural flood plain. On the eastern side, except for a small northern section, the area drains to the west by way of a series of smaller catchments. Except for Ngaooraa National Park (formerly Worrigee Nature Reserve) most of the area has either lost its natural vegetation or what small percentage that remains has been disturbed. While this lessens its conservation value, it makes the remaining vegetation important to the landscape character. Vegetation throughout the area generally consists of Ironbark (Berry Siltstones), Spotted Gum, Grey Gum and Stringy Bark on the high grounds. Woolbutt and Paperbark are generally found on the lower ground and alluvial drainage area. Important vegetation stands exist in the following locations:

Into and close to the Old Southern Road reserve. The unmade road running between Old Southern Road and Worrigee Road. The triangular section immediately west of Worrigee Road. The area between McKay and Park Street. South of Hillcrest Avenue adjacent to the floodway (Red Gum on the western side

and Spotted Gum on the eastern side) Along the backs of properties on the northern side of Hillcrest Avenue.

Measures to preserve this vegetation should include incorporation into public reserves and drainage reserves, use of building lines, setbacks, service roads and grouping of driveways. Also, the use of lower density (Hillcrest Avenue) or medium density with common open space could be used to conserve the more important stands.

The vegetation along Old Southern Road is of prime importance in that it is central in the area and follows the main north south ridge. The predominantly Spotted Gum is regenerating in the area south of Hillcrest Avenue. The proposed realignment of the northern section of this road to achieve the appropriate speed and safety configuration has the very important effect of preserving the major stand of trees. South of Hillcrest Avenue on the eastern side the school and the proposed recreation area offers the opportunity to impose building lines.

5.2 Road Works

The majority of the area and associated road works have been developed in accordance with the plan. The following road works are still proposed to improve traffic and transport within the area.

A new link road between Old Southern Road and Hillcrest Avenue is proposed to improve access to new estates to be developed west of Old Southern Road.

Quinns Lane is proposed to be upgraded to arterial road status, with minor road widening and improvements, and a new roundabout at the intersection of Old Southern Road.

A new link road between Carrington Park Drive and Park Road.

5.3 Flooding and Drainage

5.3.1 Flooding

Flooding in the area occurs along Browns Creek in the west and at the low points along Greenwell Point Road. The 1% AEP flood line has been defined in the Shoalhaven Local Environmental Plan (SLEP) 2014. The Lower Shoalhaven River Floodplain Risk Management Study and Plan

Climate Change Assessment (2011) and the Nowra and Browns Creeks Flood Study (2006) also map the flood affected areas. 5.3.2 Floodplain requirements

A floodway from Browns Creek is located within the E2 Environmental Conservation zoned land. A recent study does not identify the entire E2 zone as being floodway; however it does show the E2 extent as being the flow path in a 1% AEP flood event. If you wish to develop within the flood prone area, you must demonstrate how your development complies with Chapter G9: Development on Flood Prone Land and the following controls:

No structure shall be constructed closer than 5m from the inner edge of the flood fringe area.

Erosion protection to be provided as directed in areas where high velocity might be anticipated.

The maintenance of the flow path is considered the responsibility of the land owners. Because of the restrictive nature of the E2 Environmental Conservation zone, subdivision of the land to isolate the flow path would not be acceptable. If you wish to subdivide E2 zoned land, you must demonstrate that the E2 land has adjacent land capable of development. A series of small lots with backyards running into the flow path is also unacceptable in that fences etc. and multiple ownerships would make the flow path impossible to maintain.

An exception to this is the flow path between Hillcrest Avenue and Brown Road, where the flow path could form part of the open space system of the areas and public ownership of the flow path would be appropriate. 5.3.3 Drainage requirements

The area is broken into a series of catchments, as shown in Figure 2 above. Fortunately this, in combination with the relatively large ownership, has minimised the drainage problems. The major developments fronting Greenwell Point Road and Worrigee Road have incorporated retention basins generally corresponding in Greenwell Point Road to the 1% AEP flood event. Council's objective in the design of these structures is to ensure no additional rates of flow would pass onto the downstream undeveloped land than would be expected if the catchment was not developed. In recent times, additional requirements in relation to water quality control measures recommended by the NSW Office of Environment and Heritage have been imposed on urban stormwater discharges. It is intended that these policies would be continued for future developments (see Chapter G2: Sustainable Stormwater Management & Erosion/Sediment Control).

Note: This area is located in the Birdstrike Group Area B for HMAS Albatross. Any new artificial water bodies should consider Guideline C: Managing the Risk of Wildlife Strikes in the Vicinity of Airports contained within the National Airports Safeguarding Framework. A wildlife management plan may be required for applications proposing large water bodies to mitigate the risk of birdstrike.

5.4 Planning Proposals

5.4.1 Shopping

A shopping centre providing approximately 3,500m2 of retail floor space would be required to serve the local community. The plan identifies an area on Isa Road for a shopping centre, however this site would only provide for one third of the required floor space.

shops is a possibility in the medium term. The most appropriate locations would be adjacent to the community facility and active open space areas. 5.4.2 Environmental protection

You must demonstrate how you comply with the building lines outlined below to ensure remaining tree stands in the area are protected and enhanced:

Eastern side of Old Southern Road, between Hillcrest Avenue and Quinns Lane 20m building line.



Page | 8

Both sides of Old Southern Road, south of Quinns Lane 20m building line. North of Hillcrest Avenue Varied building lines as shown on the map.

A landscape plan must be submitted with any subdivision application which protects and enhances trees in new areas. 5.4.3 Medium density

Proposed medium density lots are to be identified on the subdivisions plan so that potential purchasers can be aware of future medium density areas. 5.4.4 Development contributions

Contributions will be levied for essential community infrastructure in accordance with the Contribution Plan.
