Precinct 4 – Katharine Street / Clayton Road 

Description:

 The Katharine St/Clayton Road Precinct comprises all land within the study area north of the 

Helena River. The precinct is bounded by Frederic Street, Scott Street, and the Helena River. 

Key Elements:

 Precinct 4 comprises an established (mostly unsewered) residential area, rural residential 

properties along Katharine Street (to the west of the precinct backing onto the Helena River), and also land 

around the Clayton Road/Samson Street area identified for further residential investigation.   

The precinct encompasses the two northern entry routes into Helena Valley being via Katharine Street to the 

northwest and Scott Street to the north. The only District Open Space in Helena Valley lies within the 

precinct at the intersection of Scott Street and Clayton Road. 

Key Considerations: 

The majority of Precinct 4 remains unsewered, with reticulated sewer provision limited to land fronting 

Frederic Street and Noel Street to the north. Opportunities for redevelopment of existing residential land 

and/or areas identified for residential investigation would be subject to the ability to provide reticulated sewer. 

This is a critical constraint for any further residential development in the area, and may deem such 

expansion activity to be a long term prospect at best.  

The retention or relocation of the District Open Space site is recognised as a key consideration.  The 

opportunity to provide a secondary facility to the southwest of Helena River and therefore service a wider 

catchment has been shown in Precinct 1. Similarly, an alternative location for the Scott Street facility is 

shown within this precinct but would require considerable further investigation and landowner consultation, 

along with associated infrastructure upgrades to facilitate improved connectivity south of the Helena River 

(e.g. new crossing at Samson Street). 

Residential investigation areas to be assessed against criteria including, but not limited to: 

 



Helena River and floodplain/flood fringe delineation and interface, and maximisation of opportunities to 

extend regional parks and recreation reserve linkages along both sides of the river; 

 

Topographical response to site contour constraints; 



 

Flora/fauna conservation considerations; 



 

The feasibility of providing reticulated sewer



 

Recognition of the Helena Valley Homestead as a site of Heritage significance; and 



 

Opportunities for medium density and/or aged accommodation having regard to the precinct’s 



accessibility and higher surrounding amenity particularly adjoining Helena River. 

The conservation and enhancement of natural assets including the Helena River and floodplain environs, 

Bush Forever Areas and any identified conservation priority areas. 

Accessibility to/from the precinct across the Helena River via a potential pedestrian/cyclist link at Samson 

Street in the short term, or full road/bridge construction in the longer term.

Retention of rural lifestyle properties backing onto the Helena River in the west of the precinct along 

Katharine Street, acknowledging the lack of further development potential given floodplain environs. Further 

subdivision and development of these properties may be achievable subject to the provision of reticulated 

sewerage, and/or the partial location of lots within the floodway/flood fringe area subject to the agreement of 

the Department of Water and provision of necessary riverpark reserves along the Helena River (to the 

agreement of the  Swan River Trust / Department of Parks and Wildlife and Department of Planning).

Precinct 5 – Helena Valley Road East 

Description:

 The Helena Valley Road East precinct comprises all rural residential land to the western extent 

of the study area generally east of properties on Ridge Hill Road and east of Scott Street. The precinct also 

includes land north of the Helena River accessed via Clayton Road and Fyfe Street. 



Key Elements:

 The Helena Valley Road East precinct is characterised by steeper sloping rural lifestyle 

properties and encompasses areas of significant bushland, together with several rural orchard properties 

around Fyfe Street to the northeast. The precinct offers a high degree of rural bushland amenity with its 

undulating topography and view corridors.  The precinct abuts Beelu National Park. The upper extent of the 

Helena River dissects the precinct running east-west.  Access to the precinct is via Scott Street from the 

north, or from the south via Ridge Hill Road. A smaller number of small holdings are accessed via Clayton 

Road and Fyfe Street. 



Key Considerations: 

No further intensification of land use is identified for Precinct 5, reflecting both the physical nature of the 

precinct, the important natural character of the landholdings, and the need to protect further fragmentation of 

the small rural holdings. 

The conservation and enhancement of natural assets including the Helena River and floodplain/flood fringe 

environs, Bush Forever Area No.215 and identified Conservation Priority Areas.  

Investigate potential construction of a river crossing at Fyfe Street to improve pedestrian/cyclist links to local 

services and the Helena Valley Primary School while assisting emergency access.

CONCLUSION AND NEXT STEPS 

The Helena Valley presents a number of potential opportunities for future urban/residential development, 

over and above that currently identified by Directions 2031, the WAPC’s Urban Development Program and 

existing MRS Urban zones. In this regard, the area has the opportunity to play a significant role in meeting 

future housing requirements of the Shire, where other localities are much more limited in their growth 

potential by local environmental and servicing constraints.  

Although a number of sites are currently in the process of being planned and/or developed for more intensive 

residential land uses, there remain a number of further opportunities for residential investigation, particularly 

in the central portions of the study area south of the Helena River.  Considering this, conservative estimates 

suggest the Helena Valley could potentially accommodate a doubling of its residential accommodation 

which, combined with significant development proposals in neighbouring Bellevue and Bushmead, will lead 

to significant additional local/regional demand for employment, services and community facilities.   

The existing topography, environmental features and servicing constraints of the area are limiting factors in 

addressing existing connectivity issues and improving access between existing/future residents and local 

services.  However, a number of opportunities have been identified in this study for further investigation, 

which may help to increase local service provision and improve functional linkages between residential 

communities north and south of the Helena River (along with neighbouring areas of Bellevue and 

Bushmead).   

The findings and recommendations of this study are intended to inform the development of an urban 

expansion strategy for the Helena Valley, which will set out publicly the Shire’s expectations for the area in 

terms of planning principles, zoning preferences and key connections, and provide a guide for future 

rezonings and/or structure planning for future development sites.
