What is the Scope of theProject? Aim: The overall aim for stormwater in the City of Casey is: To maintain a healthy system of waterways that protects the diverse ecological values of the waterways and the ultimate receiving waters of Western Port and Port Phillip Bays, while also minimising flooding and providing the community with the opportunity to enjoy the recreational and economic benefits of well maintained waterways. The purpose of the Casey Stormwater Management Plan is to protect and enhance water quality. This is expected to be achieved through : General Strategies: Partnering & Implementation, Planning, Operations, Enforcement, Infrastructur e, Education; and Specific Strategies : Subdivision & Development, Residential, Commercial, Industrial, Open Space, Agricultural, Rural settlements, Coastal.
Timeline of the Project. The project incorporates a series of general and specific strategies which are aimed at achieving the overall objective of the plan. These strategies include specific actions which are designed to, through their completion, facilitate achievement of each strategy. Each action includes it’s own time line from immediate completion to five years, at which point it will be re-evaluated for success.
Regulatory frameworks. This project conforms to the following regulatory frameworks and policy documents: CSIRO Urban Stormwater Best Practice Environmental Management Guidelines EPA Construction Techniques for Sediment Control EPA Environmental Guidelines for Major Construction Sites EPA SEPP Waters of Victoria
More details on scope There were a total of 14 strategies which were identified within the scope of the project described. Some were broad, while others were more specific. All were pertinent to the objectives of the project, but an excellent example would include the Public Infrastructure strategy which included, as action 2 (PI2), the instigation of a program to detect illegal sewerage connections [to stormwater] and have them disconnected, as well as repairing leaking sewers as soon as practicable. This would help reduce the E.coli and BOD measurements (which were generally above the appropriate SEPP guidelines) and protect the beneficial uses of waterways in the region as identified under the appropriate water quality and drainage SEPPs.
Evaluation It is difficult to gauge the success of the project holistically. However, a further report, undertaken by the Council in 2004, identified strengths and weaknesses of the original project, as well as the varying success of different strategies undertaken between 2000 and 2004. For some strategies, such as the Town Planning strategy (PI), and the Design and Development strategy (SD), 100% of the actions undertaken have been successful. Others, such as the Education strategy (Ed), only experienced partial success (when measured through successful implementation of devised actions), with several strategies being unresolved due to a combination of a lack of funding and unclear definitions of roles. This being said, no strategy had met with a 0% success rate in terms of achievement of described actions. Overall, it could be argued that, while not completely successful, the project has been largely successful and, where it has failed, the 2004 report has identified ways in which it can be improved – such as more specific and clear roles and responsibilities for the council and other stakeholders, or more funding in some areas.
