We have developed a web-based collaborative mapping tool, known as Hydra, to support IWM partners to:
- understand and build on the work that has already been undertaken within the forum areas through case studies
- identify new IWM issues and opportunities
- communicate the benefits of applying a place based IWM approach.
DELWP’s Developing integrated water management plans – a process of analysis provides guidance on engagement with different groups, technical analysis and assumptions, options evaluation and drafting and finalising an IWM Plan.
These guidelines are specifically targeted at project managers and project teams as they undertake the various steps and different analyses involved in the preparation of IWM Plans. Following the approach outlined in this guidance may assist in applying the cost-benefit allocation framework and building business cases for integrated servicing solutions.
This document has been developed to provide guidance on preparing local government, and other water sector organisations, for the IWM Forums. This practical ‘how to’ sets out a process to deep dive into identifying and prioritising priorities for collaboration. It can be used internally or as part of a facilitated workshop.
IWM strategies can include a wide range of management options that can affect one or multiple aspects of the water cycle. Options can be implemented at a range of scales, from regional to precinct to lot. They can utilise different sources of water, satisfy different demands for water, and use a range of local or regional infrastructure for storage and treatment.
Feedback to DELWP has indicated that the process of shortlisting these options can be challenging. The Preliminary Assessment Method (PAM) provides guidance on shortlisting options, brings together lessons and data from previous IWM strategies, and provides a methodology framework to aid shortlisting in a time-effective yet robust manner.
The PAM should not replace detailed analysis of option portfolios or underpin business case proposals. It is only intended as a high-level assessment method to aid shortlisting.
Local projects and servicing plans developed by IWM Working Groups will proceed through economic evaluation and approval processes that are determined and accepted by the IWM partners involved. In most cases, cost-benefit analysis provides a robust method for evaluating the costs and benefits (including both market and non-market impacts) of a project. A multi-criteria analysis can also be used where the major benefits cannot be valued or are impractical to value. IWM Plans and projects often propose innovative investments that provide multiple benefits to many different entities.
An integrated solution may lead to costs that would typically not have been incurred by the project partners through traditional projects under current regulatory settings. However, the additional costs do not necessarily change at the same scale as additional benefits, and can be concentrated on one or two specific entities. Funding streams and cost recovery mechanisms are not always apparent. This can present a barrier to some IWM projects.
DELWP has developed a cost-allocation process to respond to this issue. This provides a process to guide decision making on funding arrangements in such situations. The cost-allocation framework will be further developed and tested collaboratively by DELWP with other Victorian Government departments and the water sector.
This approach may identify a new interested organisation willing to co-invest to achieve the benefits identified. A strong project prospectus that describes the benefits and presents a sound value proposition can be a key tool to leverage external support. This can also be key to achieving opportunistic support and funding when the implementation context or strategic drivers change for a project or plan that has not been adopted due to funding issues.
Externalities valuation focuses on assigning values to costs and benefits that are not obviously monetised, such as the community benefit of amenity improvements. Valuing externalities for integrated water cycle management planning is a DELWP-commissioned study that provides a first point of reference when undertaking IWM analysis that involves externalities. Although guidance on the use of externality data is provided in this document, it should be recognised that appropriate economics expertise is important when applying it. As with many technical disciplines, the 'devil is in the detail' and the robustness of the economic assessment is heavily dependent on the conditions under which the information is applied. This topic is an acknowledged gap and work to improve understanding of this area is continuing.
DELWP has partnered with the City of Ballarat to develop Planning a Green-Blue City, a how-to guide for planning urban greening and enhanced stormwater management. This guide has been developed to assist cities and towns in planning for increased presence and effectiveness of green-blue infrastructure in their urban areas. It is designed to assist local governments and their partners in:
- developing a robust and locally tailored evidence base for the need to promote green-blue infrastructure opportunities
- identifying green-blue infrastructure opportunities at all scales
- reviewing opportunities for greatest community benefit and value
- determining priority projects and key actions
- identifying delivery pathways and funding mechanisms.
The guide will allow local governments to develop the necessary components of a green-blue infrastructure action plan that will inform and drive local government-led initiatives.
The 202020 Vision (20V) is a mass collaboration of organisations working together to create 20 per cent more green space in our urban areas by 2020. DELWP partnered with City of Melbourne and 20V to develop How to Grow an Urban Forest. This document serves as a guide for other councils to follow in the development of their own strategy for urban greening and aims to:
- understand the process and methodology that made the City of Melbourne’s Urban Forest Strategy a success – and adapt this for the benefit of other councils
- condense and simplify this into a methodology that can be applied and adapted to most urban councils in Australia, to suit where they are located, their political context and the resources they have available
- scale and replicate by providing this information as a free activity-based workbook with the key elements broken down into 10 steps.
