2.4 Adjoining Development The adjoining development in Camden Road and Railway Parade consists of a mix of residential and non residential (light industrial) land uses. An early learning child care facility “Fidgety Frogs” is located next door to the north and the main southern rail line adjoins the site to the south.

2.5 Zoning The subject lands are currently zoned Residential which we understand permits the proposed residential development with the consent of Council.



3.0 DEVELOPMENT PROPOSAL

3.1 Development Concept The proposal involves the development of the land to accommodate 35 medium density units with 53 off street car parking spaces as shown in the concept plan prepared by Wayne Ellis Architects Pty Ltd. The development is proposed over 35 one and two storey dwellings, which includes car parking for residents and visitors with access off Camden Road. The proposal envisages 2 x 1 bedroom, 15 x 2 bedroom and 18 x 3 bedroom villas and on site car parking for 53 resident vehicles plus 12 visitor spaces.

3.2 Layout and Guideline Standards The site layout has been designed generally in accord with AMCORD Guidelines for new residential development. Within the site, low speeds are desirable in lightly trafficked area to protect pedestrians, cyclists and allow them to share the access areas with vehicles. Bus routes servicing the precinct should be within acceptable walking distance (400 metres) of all dwellings. The aims of the proposal are to achieve:

Convenient and safe access to all units for pedestrians, vehicles and cyclists

Safe, logical and hierarchical transport linkages to the existing street system

Appropriate access for emergency and service vehicles

A quality product that minimises maintenance costs

A convenient way for public utilities

An opportunity for landscaping

Convenient on and off street parking for visitors AMCORD and RMS Guidelines recommends the following standards for the various classes of roads in newer subdivisions. These roads should in terms of amenity and road safety afford the following environmental capacity/performance standards.

Road Class Road Type Desirable Max. Speed (km/hr)

Desirable Max. Peak Hour Volume (veh/hr)

Local Accessway (with footpath) Street

25 100

Street 40 200 environmental goal Street 40 300 maximum

Collector Street 50 300 environmental goal Street 50 500 maximum

In this regard Camden Road is viewed as a collector Road and Railway Parade is a local road.



Adequate stopping and sight distances will be provided for horizontal and vertical curves at all access intersections as follows:

40kph minimum stopping sight distance 30 metres

3.4 Parking Wollondilly Shire Council’s off street car parking policy for Medium Density Residential Dwellings DCP 2016 Volume 4 adopted on 1 January 2016 suggests on-site car parking be provided at the following rates and provisions:

A minimum of one (1) parking space shall be provided on the site for each dwelling. Such a space, or spaces may be an open hard stand space or a carport or garage, whether attached to or detached from the dwelling.

An open hard stand car parking space must measure a minimum of 2.6m wide by 5.4m long.

A minimum of one (1) visitor parking space per three (3) dwellings (rounded up) must be provided wholly on the site. Such a space or spaces may be an open hard stand space or car port of a garage, whether attached to or detached from the dwelling. Visitor parking must be appropriately signposted on the site.

A minimum of one (1) parking bay measuring a minimum of 2.6m by 5.4m shall be located on the site and dedicated as a vehicle wash bay. The wash bay shall be within adequate distance of a water source (i.e. a tap) and shall drain to a landscaped area on the site.

Garages shall have sufficient area to accommodate a parking space of 2.6m x 5.4m per allocated parking space.

Garage doors shall have a minimum width of 2.4 metres.

The width of any access driveway and the overall design of the development shall enable vehicles to enter and leave the site in a forward direction.

Provision shall be made for footpaths/sharepaths/cycleways to be provided to the nearest available network connection to the village centre in accordance with Council’s Design Specifications.

3.5 Cycleway Facilities Provision for cyclists in Camden Road and or adjoining access routes is limited to on road facilities sharing the existing roadways within the existing 50km/h residential precincts of Douglas Park.

3.6 Public Transport In a broader regional context the site can be serviced by public transport comprising buses, taxis and trains. Trains are mostly used for trips between the adjoining towns of Picton and Campbelltown and to locations outside the Shire. Regular bus services are provided to Picton and Campbelltown. Existing bus stops are located along Camden Road. Bus services are provided by (local) private bus operators who provide regular services for the general public as well as school bus services. Taxis are available in Picton and between the adjoining towns for people who choose not to use buses or who need to get from their residence to the shops or the railway station.



In the longer term future residential land release areas and land subdivisions can affect the delivery of public transport services by providing more people and good traffic circulation routes encouraging private bus operators to extend and increase the frequency of services.

3.7 Waste Management The development will be provided with on-site waste management facilities to allow for: a) The collection of domestic waste from each dwelling; and b) The storage of waste out of sight of any publically accessible place, dwelling

window, area of private open space and area of common open space; and c) The collection of domestic waste from the development by waste collection

vehicles; and d) On site storage and collection of waste.



4.0 EXISTING TRAFFIC ASSESSMENT

4.1 Existing Road System Within the Douglas Park road hierarchy Camden Road is a 13 metre wide (kerbed) local access street running north/south between Menangle Road and the site and thence onto Douglas Park Drive. The alignment is straight and the topography generally level. Camden Road is located in a 50 km/h residential precinct and is accessed from either Menangle Road or Railway Parade via Douglas Park Drive which (functionally) is a collector route between Menangle Road and Railway Parade.

The tee junction of Camden Road with Railway Parade is controlled by “Give Way” signs. Railway Parade is an unkerbed local access road (dead end) with a variable width pavements to 7.0 metres. The site is also adjoined by the Main southern rail line and the at grade level crossing in Camden Street is controlled by boom gates and flashing lights.

6. Level crossing

4.2 Existing Traffic Volumes & Conditions 4.2.1 Average Daily Traffic (ADT) Existing traffic volumes for Camden Road and Railway Parade are not to hand but based on the current level of development and road function daily and peak hour 2 way volumes are expected to be less than:

Camden Road – 2,000 vehicles per day and 150 vehicles per hour two way in peaks

Railway Parade – 200 vehicles per day and 30 vehicles per hour two way in peaks



4.3 Service Levels & Amenity Existing traffic service levels in Camden Street and Railway Parade can be described as very good, i.e. low traffic volumes and 85th% free flow speed around 50km/h. In keeping with the RMS and AMCORD Environmental Capacity Performance Standard for local residential streets of less than 200 veh/hr as an environmental goal and up to 300 veh/hr as a maximum before amenity is compromised. Camden Road currently has a relatively high level of traffic amenity LOS A.

4.4 Road Safety The existing level of road safety along Camden Road and Railway Parade is considered to be acceptable due to good sight distances, low traffic volumes, moderate free flow traffic speeds and minimal traffic, pedestrian and cyclist activity to/from adjoining residential and non residential properties. A review of the RMS crash data base, 3 years to mid 2017 did not reveal any history of vehicle accidents at the site or in Camden Road at Railway Parade. The proposed access location (at the northern end of the site frontage with Camden Road) is so located to minimise any potential conflicts with traffic queueing from the at grade rail level crossing or vehicles turning in or out of Railway Parade.



5.0 TRAFFIC IMPLICATIONS

5.1 Traffic Generation The RMS Guidelines 2002 suggest that vehicle generation rates be calculated for both daily and peak hourly vehicle trips. The Authority’s suggested land use traffic generation rate for medium density units and residential townhouses/villas is: Rates Units and Townhouses/units to 2 bedrooms Daily vehicle trips 4.0 to 5.0 per unit/villa Weekday peak hour vehicle trips 0.4 to 0.5 per unit/villa Units and Townhouses/villas 3 or more bedrooms Daily vehicle trips = 5.0 to 6.5 per unit/villa Weekday peak hour vehicle trips = 0.5 to 0.65 per unit/villa Factors The above RMS rates are based on surveys conducted in areas where new residential sub divisions are being built. Public transport accessibility in such areas is often limited. This company has recently undertaken investigative studies of similar new outlying residential subdivisions to establish daily and peak hourly traffic generation levels. Whilst we do not expect our findings at other urban locations in the south western Sydney region to be identical in this case, we believe there are some relevant consistencies. We have found, for example, that for newer subdivisions in middle income areas, mostly comprising young couples and young families and where public transport facilities are moderate to poor (i.e. private operated bus service only), then daily trip generation per household is between 8 and 9 movements for single dwellings and 5 to 6 movements daily for medium density residential uses. The PM peak period is normally 6 movements and the AM peak period represents only 7% of the daily total. However, based on the above (recommended) RMS rates we would suggest future traffic generation levels for the 35, 2 and 3 bedroom villas proposed are, as follows:

Daily vehicle trips units/villas (35 x 6.0) = 210 daily trips

Weekday peak hour vehicle trips units/villas (35 x 0.6) = 21 peak hour trips Whilst it is appreciated that the future traffic situation to/from the subject site is not necessarily an extension of existing low volume conditions, we believe the following factors are relevant in indicating a worst case trip generation scenario for the proposal:

Car ownership rates are likely to increase in line with those for new middle income subdivisions, housing young couples and families, and

As a worst case the morning and evening peak hour is estimated at 10% of the daily rate.



5.2 Trip Distribution RMS Guidelines also suggest that a distribution of peak hour arrival and departure journeys be undertaken to evaluate the traffic impacts on the adjoining road system. The peak hour distribution of left and right turning traffic to/from the site will be ultimately influenced by future traffic conditions, levels of service and vehicle origins/destinations regionally. For the purpose of distributing the projected traffic generation to the existing road network and ultimately determining the extent of any future traffic impacts at adjoining intersections, we have displaced the estimated traffic generation in a 50/50 proportion to Menangle Road and Douglas Park Drive north and south of the site as follows: TABLE 5.1

TRIP DISTRIBUTION

AM Peak Hour 21 Trips

PM Peak Hour 21 Trips

Arrivals 20% 3 veh /hr

Departures 80% 17 veh /hr

Arrivals 80% 17 veh /hr

Departures 20% 3 veh /hr

Left in from Camden Road 10%

Left out to Camden Road 40%

Left in from Camden Road 40%

Left out to Camden Road 10%

Right in from Camden Road 10%

Right out to Camden Road 40%

Right in from Camden Road 40%

Right out to Camden Road 10%

NB. Volumes are expressed as % of total additional traffic. The above traffic distribution equates to an additional 17 outbound and 3 inbound trips on Camden Road during the (Mon-Fri) AM peak hour with a reciprocal flow during the PM peak.

5.3 Post Development Traffic Conditions The ease at which traffic can enter or leave the development site will be directly related to future gaps in opposing traffic flows along Camden Road currently around 150 veh/hr during peak hours. Additional traffic movements to/from the subject site are likely to be around +21 veh/hr. The total two way peak hour flow of traffic on Camden Road will increase to about 170 veh/hr (or approximately 3 vehicles every minute). In our view, it is unlikely the existing traffic service levels, road safety or amenity threshold will be compromised by the additional traffic volumes or the interaction of traffic entering and exiting the existing access intersections as proposed.



6.0 CAR PARKING AND ACCESS ASSESSMENT

6.1 Parking Provisions Wollondilly Shire Council Parking Code DCP 2016 requires a parking requirement of 47 spaces (including 12 visitor parking spaces). The development will provide a total of 53 parking spaces in garages with each dwelling plus 12 outside ground level visitor spaces, total 65 spaces. Accordingly, in our view, the proposal complies with the quantative number of parking spaces required. The general parking layout complies with Council’s Parking Codes. There is also sufficient on site manoeuvring to cater for servicing of the commercial use for trucks up to 6.4 metres. Delivery vehicles will be vans or small rigid trucks and these vehicles can also be accommodated on the ground level parking area.

6.2 Access and Circulation Car access to the site is from a combined entry/exit driveway 6.0 metre wide to Camden Road will allow sufficient room for 2 vehicles to pass and queue on site. Smaller service vehicle access is also via the proposed 6.0 metre wide crossover to Loftus Street. The on site car park is generally designed in accordance with AS 2890.1 and Council’s Parking and Loading Code, with respect to parking spaces, size and circulation aisles and provides adequate manoeuvring room for vehicles using the car park. All vehicles will enter and leave the site in a forward direction. An overlay of the 85th% design vehicle turning template (extracted from AS 2890.1) indicates that all 85th% vehicles or similar can access and leave all car parking spaces and turn around (generally with a 3 point turn) within the two way aisleways provided. The turning manoeuvre for a small rigid truck to 6.4 metres indicates that this vehicle can enter the site in a forward direction, reverse into the loading area and exit the site in a forward direction.



7.0 CONCLUSIONS

The following conclusions may be derived with respect to this proposed medium density residential complex (35 units) at Camden Road, Douglas Park.

The use will occupy a site area of 14255m2 currently vacant, north of Douglas Park Railway Station.

Sufficient parking is proposed on-site (65 spaces) for all residents, tenants and visitors. The total parking facilities provided are, in our view, sufficient for the likely peak parking demand and more than required under Council’s DCP.

Additional and ample on street car parking is also available in Camden Road but utilisation of these spaces is not part of the proposal.

Based on the RMS (RTA) traffic generation guidelines it is estimated that an average of 21 peak hour trips including 1 service/delivery vehicle trip will be generated in AM/PM peaks by the site’s post development use in the future.

These low peak hour volumes should dictate that there will be no significant effects on adjacent traffic flows, pedestrian safety or the operating performance adjoining the intersections, the surrounding road network or existing bus services.

Our site inspections indicate the existing peak hour traffic flows and pedestrian volumes on the road system near the site are low, with minimal delays at the adjoining intersections.

The primary point of site access will be to/from Camden Road at the mid point of the site via a two way 6.0 crossover and driveway opposite Railway Parade.

The access driveway is located as far as practicable from existing driveway and the existing at grade level crossing to minimise any interference to traffic operation or turning movements.

The proposed development including the new access provisions will meet the requirements and guidelines of the Roads and Maritime Services in terms of road safety and network efficiency.

The manoeuvring layout and parking arrangements are adequate and in accordance with Australian Standards.

The parking provisions and number of on site parking spaces proposed are in line with the Wollondilly Shire Council’s Parking Codes.

Recommendations Our findings are that the use of the site and a rationalisation of the access treatments to Camden Road will not have any detrimental impact on surrounding land uses, the community or traffic flows and pedestrian safety/amenity in Camden Road. On the basis of this report it is recommended that Wollondilly Shire Council support the development proposals and approve this application to enable these site changes and the development of a medium density residential unit complex to occur in the Douglas Park precinct.
