Final Report Multi-use Recreational Pathway Concept 11. Blacktown Creek and Tributaries 11.1. Description ◦ The main creek corridor runs from McCoy Park at the junction of Greystanes Creek, Blacktown Creek and Toongabbie Creek to McCoy Street (Parramatta / Blacktown Council boundary) and then to south of the Western Freeway near Watch House Road ◦ Two tributaries were identified and investigated: ∙ Boyd Street Tributary, which runs from the main creek to Boyd Street reserve, east of the Blacktown CBD ∙ McCoy Street Tributary, which runs from Blacktown Creek at McCoy Park to the Toongabbie local shopping centre at the intersection of Best Road and Mackenzie Boulevard. 11.2. Network Significance (creek, pathway, environment) The pathways in the Blacktown Creek corridor partly form the spine access network and partly provide local and regional access: Spine Access Network ◦ Blacktown Creek - McCoy Park to Boyd Street Tributary ◦ Boyd Street Tributary – main creek to Seven Hills Road Local and Regional Access Routes ◦ Blacktown Creek – Boyd Street Tributary to Western Freeway ◦ McCoy Street Tributary 11.3. Environment Management There is remnant bushland on Blacktown Creek near the Great Western Highway. There is no need for any pathways to access this area. 11.4. Land Tenure There are several options for the location of pathways between International Park in Blacktown, Seven Hills Station and Greystanes Creek. In the Upper Parramatta River catchment, the general preference is for the development of routes within the creek corridors rather than on-road or in other corridors. Blacktown Council is considering the development of a route along the road network south of the railway. There are also opportunities for routes within the rail corridor. All options require some negotiation with land owners. The development of pathways in the Creek corridor would require detailed investigations about the Transfield site adjacent to Powers Road. Negotiations with SRA may be required in all cases, possibly for widening of the pathway to the south of the multi-storey carpark at Seven Hills Station (creek corridor option) or for a pathway in sections of their easement south of the railway adjacent to the Boomerang Place carpark and from Abigail Street to Cecelia Street. 60 Jamieson Foley Traffic & Transport Final Report Multi-use Recreational Pathway Concept Negotiations with SRA may also be required for use of their land between the main southern arm of Blacktown Creek at Endeavour Street and Seven Hills station. 11.5. Other Issues No other issues were identified. 11.6. Pathway Opportunities Blacktown Creek ◦ Through McCoy Park there is some evidence of existing walking tracks, but these they lead up a steep hill to the sports ground, which would be difficult to negotiate for cyclists and walkers. It would be better to select a new route that more closely follows the creek line, which would require little or no grade change. There appears to be a wetland area here and there may be environmental sensitivities. Flooding may also be an issue. Blacktown Creek, McCoy Park Blacktown Creek, east of Station Road ◦ From the western perimeter of McCoy Park to Station Road the creek runs through a concrete lined canal some 10m wide with 3m high angled concrete edges. There is dense vegetation growth within the canal, particularly reeds. Property boundaries on both sides immediately adjoin the top of the canal wall. Several small business operate close to the edge of the canal on the southern side. On the northern side, Transfield appear to own a large industrial warehouse site and may be prepared to negotiate about a pathway within their property. Further investigation is required about land tenure and site conditions. ◦ A high quality crossing facility would be required at Station Road, due its high relatively high volumes and speeds. It may be possible to use the culverts under Station Road, but water flows appear to be permanent with potentially high and frequent inundations. Blacktown Creek, Transfield site ◦ From Station Road to Powers Road, there is little or no access to the northern bank. The southern bank is generally wide, with high levels of maintenance, possibly in relation to a high security fence to the adjoining property of Cerebos (Australia) Ltd. It appears they may be sensitive to increased usage levels of the creek corridor adjacent to their property. Close to the Powers Road bridge over the creek, the bank width narrows considerably and widening or boardwalks would be required to accommodate a pathway. Blacktown Creek, Cerebos site ◦ Between Powers Road and Seven Hills Station, there is an existing multi-use pathway. 61 Jamieson Foley Traffic & Transport Final Report Multi-use Recreational Pathway Concept ◦ At Seven Hills Station, there appear to be several opportunities to cross the Prospect Highway: Blacktown Creek, culverts at Seven Hills Station ∙ Use the culverts. Further investigation is required. Refer Action items at the end of this document. ∙ Use the bridge. While it would require only minor works to extend the pathway and create some high quality road and ramp crossings, it would involve an unpopular detour, which few users would appreciate. ∙ On-road in Terminus Road. Even though Terminus Road provides a slow speed environment, the dense traffic conditions and complex movements in the area make it an unsuitable environment for many user groups. ∙ Create a detour around the eastern perimeter of the multi-storey carpark, widen the footway between the carpark and the railway and utilise the existing facilities west of the station access ramp. The intensive usage levels in this area need to be considered. Further investigation is required in terms of land tenure and land availability, particularly if a narrow section of railway land is to be used. Blacktown Creek, existing bridge at Seven Hills Station Blacktown Creek, route option east of multi- storey carpark ◦ As an alternative to a link in or near the creek corridor between McCoy Park and Seven Hills Station, it may be more appropriate to consider a link along the southern alignment of the railway, using a combination of on road and of-road facilities. While the general preference for pathway within the Upper Parramatta River catchment is for a route within the actual creek corridors, this alternative route would be closer to the residential community, which is a significant advantage in terms of access and supervision (the creek corridor is industrial and inaccessible). Council’s current plans pre ›fer this general location, which includes the following alignment (from east to west): Opportunity for alternate route south of railway ∙ Link with existing Greystanes Creek trail at the intersection of Junia Avenue and Portico Parade. ∙ Use southern perimeter of railway easement to Abigail Street, which requires discussions with SRA. Alternatively an on or off-road facility could be considered along Portico Parade with high quality crossing facilities of side streets, but this would be a lower standard facility that may not be easily used by all age groups and could be cumbersome for commuters. Council’s plans favour the on-road option. ∙ Best Road Park to eastern edge of Boomerang Street car park, upgrading a short section of narrow pathway with a poor surface. ∙ Rail corridor along the car park. ∙ On-street adjacent to the station, using a high quality road crossing facility of Boomerang Street at both side of the station. ∙ Widened shared path on the western off-ramp of to the Prospect Highway at the railway overbridge. ∙ Pathway on the western side of the railway overbridge. Boomerang Street carpark 62 Jamieson Foley Traffic & Transport Final Report Multi-use Recreational Pathway Concept Blacktown Creek, railway culverts at the softball fields Blacktown Creek, south of Bungarribee Road ∙ Improved link from the railway overbridge to the existing pathway along Blacktown Creek with a high quality road crossing facility over Terminus Road. ∙ Between the Seven Hills station and the creek junction near the softball field, there is an existing multi-use pathway, which continues into the Boyd Street Reserve tributary (refer following pages). Crossing the creek and the railway is a key issue and requires a significant bdge over the creek, while it may be possible to adjust culverts under the railway. Refer Action items at the end of this document. If this is possible, the crossing facility here may provide a more attractive option for crossing the railway instead of the railway bridge of the Prospect Highway at Seven Hills station. The pathway could be placed within the rail corridor between the creek and the station. Further investigation is required of this crossing facility and the availability of railway land. ◦ The main stream of Blacktown Creek continues south across Wall Park Avenue, Blacktown Road, Bungarribee Road, Lancelot Street, the Great Western Highway and the Western Freeway. Generally, the reservation provides grassed areas that are of ample width for tracks on either side of the creek. Between Bungarribee Road and Lancelot Street the creek runs through a shallow concrete swale drain with small amounts of water. While there currently is some cycling and pedestrian traffic using the swale drains, the do not provide a high quality pathway and it would be appropriate to provide a separate pathway specifically designed for cycling. High quality, at-grade road crossings are required, including upgrading of some existing facilities. There are a few short sections of generally narrow pathway, which would need to be upgraded: ∙ Endeavour Street to Wall Park Avenue ∙ St Martins Crescent to Cavendish Avenue ∙ Through the reserve on Lancelot Street (this reserve appears to have recently been re-established including potentially environmentally significant wetlands) Blacktown Creek, swale drains looking south towards Lancelot St Blacktown Creek, Lancelot Street Park ◦ Adjacent to Desley Crescent, immediately north of the Great Western Highway the creek appears to follow a more natural alignment, adjacent to an environmentally significant bushland area. It may be inappropriate to extend the pathway beyond this point, especially given the limited extent of urban development south of the Highway. Access to the Boral site is probably more appropriate via Greystanes Creek as described below. Blacktown Creek, Myrtle Street Reserve ◦ It was not possible to investigate pathway opportunities south of Desley Crescent. 63 Jamieson Foley Traffic & Transport Final Report Multi-use Recreational Pathway Concept Boyd Street Tributary ◦ There is an existing pathway on the northern side of the creek, which continues from the pathway along the main creek that starts at Seven Hills station through to Boyd Street. Some sections of the pathway are not well defined such as near the softball fields. Improved signposting is required as well as some surface improvements. Boyd Street Tributary, existing pathway south of softball fields ◦ The pathway finishes at the car park of the aquatic centre and resumes in Boyd Street, with an off-road shared pathway along the eastern / southern berm of Boyd Street and Devitt Street. The onroad mixed traffic arrangement in the car park is not ideal and it may be possible to create a pathway behind the aquatic centre and between the railway and the substation, which would require negotiations with the electricity provider and the State Rail. ◦ Council is currently considering crossing facilities over the railway and into the Blacktown CBD, including footpath widening along Sunnyholt Road. Boyd Street Tributary, pathway opportunity at substation McCoy Street Tributary ◦ The McCoy Street tributary is a minor waterway only, which was dry at the time of inspection. It largely follows the power lines. There is an existing footbridge over the railway along McCoy Street. The reserve between Ross Street and McCoy Street almost links to Best Road, except for short section immediately adjacent to Best Road, which appears to be in private ownership, although it is not built on.
