ABSTRACT
Tasman District Council (TDC) manages stormwater drainage systems in 15 Urban Drainage Areas (UDAs), located in varying environments from inland towns such as Murchison to coastal villages such as Ruby Bay. The UDAs differ in scale such as Richmond with a population of 18,000 and large greenfield development to areas in Golden Bay with a smaller number of permanent residents and booming summer population. In total, TDC manages over 14,000 individual property connections, 187 kilometres of stormwater pipes, 10 stormwater detention dams, and 15 kilometres of maintained channels.
Stormwater strategy and planning at Tasman District Council (TDC) has progressively evolved over the past five years to adopt a catchment-based approach for service delivery and infrastructure spending. This approach, known as the Stormwater Catchment Management Framework, consists of three key components, including the Urban Stormwater Strategy, the district-wide urban stormwater discharge consent, and the suite of Catchment Management Plans (CMPs) required under the consent to be developed for each UDA.
