Priority infrastructure plan (PIP) 7. Public realm design guidance Introduction • Streets are a key component of Brisbane’s public domain • Part of urban open space • Key pedestrian connections • Contribute to city’s subtropical character Verges • Contribute to the character of the street corridor • Width & vertical elements • Street trees frame the road and adjacent buildings • Provide access for pedestrians to adjacent buildings and uses • Connections between destinations • Access to public transport • Appearance will vary and be specific to a locality through the variety of transitions, built forms and street trees that will characterise different neighbourhoods Streetscape Hierarchy Overlay • Creates consistent footway treatments, suitable to the adjacent land use and volume of pedestrian traffic • Develops public footways with emphasis on pedestrian connections, spaces for meeting and increasing shade, amenity and visual quality • Increases subtropical vegetation to reduce the urban heat island effect and to reinforce Brisbane’s character as a subtropical city • Achieves the consistent use of a simplified, standard palette of materials Assessment Criteria Location Applicable code / PSP Section number Streetscape hierarchy overlay code 8.2.20 Infrastructure design planning scheme policy SC6.16 – Chapter 2 – 2.5 SC6.16 – Chapter 3 – 3.7 & 3.8 SC6.16 – Chapter 5 SC6.16 – Chapter 6 Planting species planning scheme policy SC6.24 Policy Comparison Brisbane City Plan 2000 • Some neighbourhood plans included limited provisions for streetscape hierarchy • Suburban Centre Improvement Projects (SCIP) localities required streetscape upgrade • Location map for streets requiring upgrade within both neighbourhood plans and the Centres Detail Design Manual • All street sub-categories except industrial street Brisbane City Plan 2014 • Streetscape hierarchy overlay code applicable citywide • Streetscape hierarchy reflects Brisbane City Council’s intent for streetscapes across the city • Overlay will continually be updated through neighbourhood planning processes • SCIP areas identified in overlay as locality street • Citywide mapping in the Streetscape hierarchy overlay map • New sub-category - Industrial street Policy Comparison Brisbane City Plan 2000 Brisbane City Plan 2014 Streetscape hierarchy overlay • Installation of the wildlife movement solutions required in some local and neighbourhood plans • Wildlife movement solutions locations shown on Streetscape hierarchy overlay map Infrastructure design PSP • Public realm design guidance located within the Centres Detail Design Manual • Public realm design guidance located within the Infrastructure design planning scheme policy (IDPSP) Policy Setting Provide sufficient space that can be designed and embellished to accommodate: • high levels of pedestrian movement and activity in consistent and high-quality treatments • large subtropical tree planting and the retention of existing trees to make a significant contribution to shade tree cover, amenity and city identity through a contribution to a sense of arrival and to create landmarks • safe movement of wildlife along a corridor Overview of Changes Introduction of citywide application of the Streetscape hierarchy—code and mapping Introduction of Industrial street sub-category Public realm guidance Conversion of the Centres Detail Design Manual into Infrastructure design planning scheme policy Streetscape Hierarchy Overlay Code Streetscape hierarchy overlay map identifies: Subtropical boulevard—in centre & out of centre City street—major and minor Neighbourhood street—major and minor Industrial street Cross block link—in centre & out of centre Corner land dedication Locality street Laneway Streetscape Hierarchy Overlay Code Development requirements • Linear land dedication - where required to ensure verges are wide enough to support high levels of pedestrian movement &/or accommodate street tree planting • Verge and kerb treatments that establish a high-quality subtropical streetscape with a strong pedestrian amenity focus and include street tree planting, street furniture, paving and lighting • Corner land dedication • Cross block links (plus signage) • Public art (limited circumstances) Assessment Criteria Performance outcomes Acceptable outcomes PO1 Development must improve pedestrian movement and amenity by providing for verges to a width that is appropriate to accommodate large subtropical street tree planting and high levels of pedestrian movement AO1 Development ensures that a verge is provided via a linear land dedication to create a minimum verge width as specified in Table 8.2.20.3.B and the streetscape locality advice and road corridor design standards in the Infrastructure design planning scheme policy PO2 Development must construct verges including street tree planting, street furniture, paving, lighting and verge and kerb treatments that establish a high-quality subtropical streetscape with a strong pedestrian amenity focus AO2.1 Development ensures that existing street trees are retained and protected AO2.2 Development ensures that street tree planting, street furniture, paving, lighting and verge and kerb treatment are designed and constructed in compliance with the specifications of the streetscape locality advice and road corridor design standards in the Infrastructure design planning scheme policy Relationship with Priority Infrastructure Plan (PIP) • Trunk infrastructure is considered in the PIP • Cross block links are only infrastructure covered by Streetscape hierarchy that is trunk infrastructure • All other streetscape hierarchy types are considered non-trunk infrastructure and therefore are not considered in the PIP Public Realm Design Guidance Schedule 6 -
