Presented at AITPM SA Back to Basics event, October 2018

1. King William Road Curated Street
AITPM Half-day Seminar
19 October 2018

2. Background
Pavement Condition
– requires full
renewal
High and increasing
vacancy rates (as at
2014)
Change in retail
uses – concern of
increase in café/
restaurant uses and
loss of retail shops

3. 2014 Masterplan
Introduced Curated
Street concept
Intersection Treatments
Phased renewal of road
pavement to minimise
impact to trade
Future flexibility for use
of space
Limited changes to
parking – still seen as
critical by traders

4. 2017 Visitor Perception Study
Mission and objectives:
“To explore perceptions of the King William Road precinct along
with visitor demographics and visitor behaviour”
Objectives
• Measure business vs visitor perspectives of King William Road
• Profile visitors and local residents (including a wider region target
audience)
• Explore issues and concerns for visitors, residents and business
• Understand how best to meet the needs of visitors
• Identify priority areas for improvement and how best to engage with visitors
and business
In depth business interviews, online visitor sample survey and follow up
phone survey

5. Perception Study Key Findings

6. Detailed Design Study
• Upgrade the road pavement and streetscape
• Ongoing market research and background studies by Council
• Three stage consultation process with landlords/traders,
community and stakeholders
• In depth design analysis of all project disciplines:
• Streetscape, landscape and public realm amenity
• Civil design
• Stormwater assessment and design
• Parking and pedestrian surveys, traffic signal intersection
assessment
• Lighting and electrical assessment
• Smart technology and future proofing
• DDA assessment
• Public art

7. Design Development
Development of 3 Options
Beautiful Street
• Most change
• Fewest car parks
• More outdoor areas
Active Street
• Modest change
• Balance between greening,
car parks and pedestrians
Accessible Street
• Retained most car parks
• Less outdoor spaces and
pedestrian crossings

8. Community Endorsement
Community engagement on the 3 design options as well
as surface treatment and kerb design
• Strong community preference for most change; more greening elements,
outdoor spaces and pedestrian crossing points, less on-street parking
• Preference for lost parking to be replaced off-street
• Desire to retain a roadway using paving
• Preference for flush treatment across road, parking and footpath; final
outcome is rollover kerb to assist with stormwater management
Provided a clear direction for the design to work towards the greater level of
change of the “beautiful street” with the rollover kerb and retained road paving

9. Design Challenges
Car Parking
• 2018 parking surveys reconfirmed 2014 surveys
• High turnover of on-street spaces generating
capacity and parking opportunities
• 2018 surveys showed capacity and lower
turnover in key off-street car parks
• Loss of on-street parking accepted by all as
parking not perceived as one of the major
visitor issues

10. Design Challenges
Car Parking Design Basis
• Retained car parking in groups of 1-2 spaces to break up the dominant
perception of cars within the street
• Generous length of spaces (6.3m+)where feasible for ease of entry/exit
• Clear width of 2.3m
• Use of removable bollards to enable change of use of parking spaces to
support event modes and tenant/land use changes
• Council to work with landlords/tenants to encourage increased development
and use of rear parking areas

11. Design Challenges
Car Parking Design Basis

12. Design Challenges
• Some capacity issues at peak periods, most
other times spare capacity
• Long cycle time for pedestrian accessibility
• Desire to reduce the area designated to vehicles
to assist adjacent businesses
Design basis – two options
• Single lane on 3 approaches, south remains as
current
• Retain some additional lane capacity on Park St
(right turn) and King William Rd north (for left
and right turn)
• Preferred option retained some additional traffic
capacity and was endorsed by Council
Park and Mitchell Street Traffic Signal Intersection

13. Design Challenges
Outdoor Dining and Public Realm area protection
• Desire to provide a safe environment for diners and public
• Limited design guidance to assist; what is available would recommend
bollards, bollards, bollards!! High cost and poor streetscape outcome
• Risk assessment approach based on:
• Nature of use, ODA higher risk than general public realm
• Vehicle encroachment risk; highest risk opposite intersections
• Reflect the likely crash risk; low vehicle speeds, potential direction
of encroachment
• Overall, the street has a relatively low risk rating due primarily to
vehicle speeds and nature of intersections
• Use of energy absorbing bollards at higher risk locations, standard or
no bollards at lower risk locations

14. Design Challenges
Other considerations
• Bus stop locations and format – one relocation proposed
• Disabled parking – desire for on-street provision but difficult to
achieve the required width mandated by the standard
• Stormwater Management
• Lighting upgrades, particularly for pedestrian crossings
• Accommodating future smart technology

15. Next Steps
• Completion of detailed design and documentation
• Final approval processes
• Construction from 2019
