Conventional design solutions are often not consistent with sustainable development principles and in many cases they are not delivering high quality places for people. Developers are encouraged to look beyond the minimum standards and consent This guide sets out best practice design principles and illustrates their application requirements of the District Plan and Engineering requirements, and to explore in subdivision and infrastructure planning and design – for both the development of opportunities that will enhance and create a better urban environment, for now and urban subdivisions and the retrofitting of existing neighbourhoods. A theme throughout which will last well into the future. this guide is generating multiple benefits such as the retrofitting of streets; provision of street calming through narrower carriageways; the implementation of low impact Subdivision designs that exhibit innovation and careful consideration of the issues urban design techniques; increased amenity through planting; and potentially with identified in the guideline, and which achieve multiple benefits, are more likely to be reduced costs of construction and long term maintenance. supported by the Council.

The Design Guide outlines design principles that new developments architects, and are expected to observe but it allows flexibility in terms of detailed design. others involved in land development and infrastructure upgrades Hastings District Council is a signatory to the New Zealand Urban Design Protocol (UDP) developed by the Ministry for the Environment. The UDP identifies seven essential design qualities that create quality urban design, known as the seven Cs. They are; Context, Choice, Connections, Creativity, Character, Custodianship and Collaboration. This guide is one of the tools the Council and the development community can use to achieve these seven urban design qualities. PG:7 Subdivision and Infrastructure Development in Hastings District - Best Practice Design Guide B DESIGN PRINCIPLES B1 Design Principles 010 PG:9 Subdivision and Infrastructure Development in Hastings District - Best Practice Design Guide B1 Design Principles The following principles were developed as part of a workshop with Council officers and others that are involved in subdivision and development in the Hastings District. SELECT They underpin the guidelines which are acceptable design solutions for subdivisions a suitable site for subdivision or retrofitting. Some locations have greater and the retrofitting of infrastructure. ability to absorb development than others and some sites are more suitable for retrofitting due to the condition of the infrastructure. They respond to the key issues and opportunities that should be addressed in the Core Principles design of subdivisions and the upgrading of above ground infrastructure which significantly influence the quality of the built environment. These principles are B1 illustrated in the design guidelines that follow. INTEGRATE natural elements, patterns and processes into the design. This could include vegetation, landforms and waterbodies to enhance the existing character, create identity and maintain and enhance natural ecosystems. RETAIN heritage and special character areas, drainage patterns, landform, view corridors, open space, natural features and links with other areas. ENHANCE ecological systems and processes in a way that accommodates development while improving ecology. Use plantings which are compatible with Hastings District ecosystems and climate, suitable for the site, and of a scale that relates to the underlying and surrounding landscape. PG:10 Subdivision and Infrastructure Development in Hastings District - Best Practice Design Guide RESPOND CHOICE to community expectations and needs, cultural diversity and climate change. of lot sizes, housing, community and recreational facilities and transportation Urban subdivisions and retrofitting should complement the local identity of options will respond to the changing needs of the community and enhance the Hastings District and respond to site, neighbourhood characteristics and the diversity of the community. local aspirations. Design for resilience to changing influences such as climate change. Core Principles B1 REDUCE DELIVER the impact of land and infrastructure development and stormwater runoff best practice subdivision and infrastructure to create great places to live, work and other infrastructure through the use of low impact design principles and and play through enabling, encouraging, engaging and exemplifying. This practices and reduce the reliance on vehicular transport through encouraging includes improved pre-lodgement processes, the use of multi-disciplinary walking/cycle friendly neighbourhoods. teams in responding to subdivision design and in the design of infrastructure upgrades and retrofitting, Council “walking the talk” through demonstration projects and through community engagement. SAFE and healthy developments are those that provide for visual surveillance over public spaces such as roads, reserves and open spaces, where traffic speeds are compatible with pedestrians/cyclists and where subdivisions are orientated to maximise solar gain. CONNECT with the surrounding community through walkways, cycleways and the roading network. This can provide greater accessibility and travel choices reducing travel distances and vehicle emissions. Connect publicly accessible open spaces and reserves to the wider recreation network.
