The purpose of this Strategy is to provide direction to the development of urban stormwater catchment management plans in the Tasman District to support the analysis, planning and management of stormwater, consolidated in urban catchment management plans and to support the development of other strategic documents.
This Strategy will provide the framework against which the assessments in the Catchment Management Plans will be undertaken. It is anchored on our vision to protect and enhance the mauri of wai / life force of water and to provide for:
Prudent stormwater management will contribute to this vision through an integrated and sustainable approach that supports economic vitality, desirable lifestyle and ecological health.
This Strategy has identified a range of goals and objectives. It also incorporates best practices to support the goals and how they can be achieve. We have identified the following long term aspirations for stormwater management:
Our fresh water and marine waters are vital to the well-being of our communities and are one of the defining features of the Tasman District. They include streams, rivers, lakes, wetlands, aquifers and springs; all discharging into the coastal marine areas of the Waimea Inlet, Tasman Bay, Golden Bay and the West Coast.
Together they form an important part of the unique culture and natural values of the district, shaping the landscape and our heritage. They are of fundamental importance to Tangata Whenua, highly valued by our residents and visitors and crucial to the health of the environment in which we live.
Our communities and the receiving environments are affected by stormwater discharges from our urban areas.
Urbanisation and other changes in land use have led to increased stormwater runoff that contribute to flooding, loss of aquatic habitat and water quality issues. It also impacts on the ability to use water for amenity purposes and food gathering.
The Council has a responsibility to manage stormwater in a way that supports the environmental, social, cultural and economic well-being of current and future generations.
The purpose of catchment management planning is to bring together the various values within a catchment to create a plan of action that is holistic and integrated.
There are three key parts to catchment management planning:
The framework map shows how they are connected.
We are in the process of applying for a stormwater discharge consent for our urban areas to authorise existing discharges under the Tasman Resource Management Plan. We believe the catchment management plans are an efficient tool in demonstrating how improvements will be made. The public will have an opportunity to provide feedback on the consent application once the consent is notified.
There are 15 urban drainage areas across our district. We aim to produce catchment management plans for all of these areas over the next five years.
Urban catchment management planning is an effective way of co-ordinating efforts to address multiple stormwater issues i.e. flood management, freshwater management, aquatic habitat management and amenity values within urban stormwater catchments.
Catchment management plans will assist the Council and communities in identifying integrated solutions to resolve existing issues and the ability to avoid or minimise risk for future issues.
Once in place they will also assist in cross-Council alignment and efficiency improvements. Although the focus of this strategy and the catchment management plans will be on the urban areas, the catchments may have up and downstream rural areas that need to be taken into account.
