How can we build
our homes and communities so that they co-exist harmoniously with
Nature? What does it mean to create a sustainable house, a sustainable
community, a sustainable city? For each additional day that we
live, design and build unsustainably, we pull another fibre out
of the fabric of Earth’s ecosystems.
A Sustainability Scorecard that can be applied to development plans and applications for new developments, and used as an educational tool by planners, developers, councillors, and the public.

How can we encourage new subdivisions and development projects to embrace the principles and practices of sustainable development? These practices have been shown in numerous studies to be beneficial:
to the local, regional and global environment
to the social life of the inhabitants,
to the strength of the local economy,
to municipal tax-payers, through reduced infrastructure costs, and
to the pocketbook of the developer.
The US Green Building Council (USGBC) has developed its LEED Green Building Rating System for commercial buildings, which is being embraced right across the market. The USGBC is in the process of developing a rating system provisionally called "LEED for Neighborhoods", which will apply to subdivisions, and similar development proposals. It is not clear how soon this will be ready; maybe in two years, maybe five.
In Texas, the City of Austin developed a Smart Growth Matrix Incentive Program which granted a developer a possible 635 points in 14 categories, rewarding high-scoring proposals with fee waivers and municipal infrastructure support. (See www.ci.austin.tx.us/smartgrowth/matrix.htm). The Incentive Program ended in Summer 2003, for reasons which I have not yet established. For a brief overview, see www.earthfuture.com/econews/back_issues/00-12.asp
In July 2001, the US National Governors’ Association adopted a set of Smart Growth Guidelines for New Community Design, which offer a similar analysis, but without the points. The text is available from the Fairfax Coalition for Smarter Growth (www.smartergrowth.org/nga_smart_growth.htm ).
This proposed Sustainability Scorecard reflects many of the accepted practices of sustainable land-use development. It has been designed for use as an educational tool to analyze and comment on development proposals. It could also be used as an assessment tool for development proposals, such that a proposal must score a minimum number of points in order to be considered by a Planning Department. The Scorecard offers developers plenty of flexibility in the way they can score the points, so it need not cramp their style.
The Scorecard has 10 dimensions, each of which contains questions allowing 10 points, for a total of 100. If it is to be applied as an objective tool, some of the points will need to be refined and developed, to allow for objective third party assessment.
The scoring of a project should be undertaken by the developer, and then ratified by the Planning Department and by a local community group (if one exists). Any differences in the scoring could then be discussed. The merit of using the Scorecard is that it sets a template for an overall vision based in the principles of sustainable development, draws the attention of developers, planners, councillors and the public to areas of a project which might be weak, and encourages improvements. It also allows Councils and developers to be proud of projects which score a high rating, and to gather the appropriate attention and publicity.
This Sustainability Scorecard was first written for the South Island Sustainable Communities Coalition, and was published in 'A Capital Idea' (Eco-Research Chair, University of Victoria, Canada, 1998). It has been refined several times, a process which continues, based on public feedback. Please send any comments or suggestions to the author, Guy Dauncey, at guydauncey@earthfuture.com .
