Drainage & Flood Mapping

The Shire has committed to a 10-year, $30 million Local Integrated Drainage Scheme to manage the impact of more frequent and intense storm events. Flood mapping of vulnerable areas continues to prove very accurate, as confirmed in a number of high intensity storms experienced throughout the year. A significant community consultation campaign has also been undertaken, with thousands of letters to affected residents informing them of the study of their catchments.

Shoreham Coastal Village Drainage Plan

Water Technology Pty Ltd was commissioned by Mornington Peninsula Shire Council to undertake a drainage plan. The issues previously identified by council officers and the community have been the focus of this study, with a preference for solutions to be practical, cost effective, environmentally sustainable and offer multiple benefits.

The project scope included identification and analysis of stormwater drainage related issues, catchment flood modelling, prioritisation of applicable mitigation solutions, and overall recommendations delivered as a drainage plan. After the initial stage of the Shoreham wide drainage investigation, further detailed investigation was undertaken at the below two high priority areas in Shoreham:

  1. Cliff Road, Sydney Road, May Street and Oxford Street
  2. Marine Parade and Fisher Street

A community engagement program is currently underway and will enhance the efficiency of the upcoming flood mitigation projects.

Protection of Balcombe Estuary

Mornington Peninsula Shire is working with Balcombe Estuary Reserves Group Mt Martha (BERG) and Melbourne Water to protect the historical and culturally significant waterway from ongoing sediment deposition originating from surrounding urbanised catchments.

Sediment generation and transportation to the estuary will be reduced through the installation of a gross pollutant trap near Henley Avenue, to capture sediment from the catchment.

The upcoming Long term Sediment Minimisation Strategy for Balcombe Estuary details a number of additional strategic stormwater management projects that the Shire will deliver in conjunction with Melbourne Water. 

Merricks Creek and Estuary Odour Reduction – Monitoring Update

Mornington Peninsula Shire is assisting Melbourne Water, Department of Environment, Land, Water and Planning (DELWP), the community working group and other stakeholders in a project to reduce odour that persistently occurs in Merricks Creek and Estuary. This odour is due to the breakdown of seagrass accumulating in the creek and affects residents in Balnarring Beach and Somers.

The Shire’s role is to monitor and assess public health impacts arising from the works conducted as part of this project.

This monitoring includes:

  • Analysis of water quality parameters such as dissolved oxygen, pH and salinity by Estuary Watch which is a community based estuarine monitoring program funded by Melbourne Water
  • Seasonal weekly testing of bacterial water quality by the Shire to assess compliance with National Water Quality Guidelines

Monitoring will continue until the completion of this project and the data will be regularly updated. Results to date indicate that the hydrogen sulphide levels near the creek and E.Coli levels in the creek have not exceeded the limits set out in relevant health guidelines.
