Report

Project 1753 – Wagga Wagga Major Overland Flow Flood (MOFF) Risk Management Study and Plan

 

WMAwater attended the Floodplain Risk Management Advisory Committee (FRMAC) meetings in May and September 2019 to advise of progress to date and to present and discuss Stage 1 and 2 reports with the Committee Report 1 – Data Collection & Model Review Report and Report 2 – Flood Damages Assessment Report. 

 

Further work has been completed on various mitigation options for the Glenfield Drain system and for Lake Albert. 

 

The report is tending towards discrete solutions in various MOFFS catchments rather than one large solution for all of Wagga. The report will provide a list of projects for Council to complete that will be local solutions but provide mitigation for the catchments as a whole. 

 

Attached for the committee’s reference is the October 2019 Project Management Office report showing the current status and timelines of this project.

 

 

Project 1793 – Main City and North Wagga Levee

 

Stage 2 of the upgrade of the remaining 6km of levee between Gobbagombalin Bridge and Kooringal Road is nearly complete. The aim is to provide a 1 in 100-year flood protection to the city for the first time.  

 

Stage 2 works involve the extension and reinforcement of existing concrete retaining walls, installation of capped steel sheetpiles and placement of clay to extend the height of the levee. 

 

The installation of 1.8km of sheetpiles is all but complete.  The capping and painting of these piles will follow on directly and be completed early in the new year. 

 

The concrete wall extension along Cadell Place and behind the Watermark complex has been completed. 

Sections of the Wiradjuri Walking Track have been reopened as the levee has been completed while other sections will remain closed for several months in sections where construction is currently taking place. The track will have a 3m wide concrete path extending from Travers Street to Kooringal Road once the project is complete 

 

Council staff are working with the contractors to minimise disruptions as much as possible and thank residents and businesses for their cooperation throughout these works. 

 

The Stage 2 upgrade is progressing a scheduled and the project will be complete in the new year.  

 

 

Project 2000 – Wagga Wagga Revised Floodplain Risk Management Study and Plan

 

Updates to FRMS&P Mitigation Measures 

 

RE1: Improve Flood Warning System

Council has been successful with a grant application to investigate options to improve our riverine flood warning system.   

 

The project will: 

 

·    review the current flood warning system 

·    assess and scope deficiencies in the current flood warning system 

·    make recommendations on additional infrastructure needs and any other improvements 

 

R1: Improved Access to Oura

Investigations into this recommendation are continuing.

 

 

Project 19555 – Flood Mitigation Option Feasibility Study for North Wagga & Floodplain Residents 

 

PR1: Investigate a Voluntary House Raising & Voluntary House Purchase Scheme in Wagga Wagga Study Area, in conjunction with, North Wagga Levee Upgrade to 5% AEP level of protection WITH an equivalent upgrade to Hampden Avenue (as embankment) and conveyance improvements through Wilks Park. 

 

L4B: Investigate North Wagga Levee Upgrade to 5% AEP level of protection WITH an equivalent upgrade to Hampden Avenue (as embankment) and conveyance improvements through Wilks Park, in conjunction with, Voluntary House Raising & Voluntary House Purchase Scheme in Wagga Wagga Study Area. 

Voluntary House Raising & Voluntary House Purchase Scheme in Wagga Wagga.  

 

The brief for this project has been out to market and Council is currently reviewing the tender submissions with a view to appointing a contractor before Christmas 2019. 

 

Attached for the committee’s reference is the October 2019 Project Management Office report showing the current status and timelines of this project.

 

 

Project 18640 – Wagga Wagga Villages Floodplain Risk Management Study and Plan

 

Stage 2 report has been submitted by GRCHydro and distributed to OEH, relevant Council staff and FRMAC members for comment.  

 

GRC Hydro have presented to the FRMAC and are due to present again at the next meeting. 

 

GRC Hydro are currently reviewing planning instruments that may be recommended to ensure that they are equivalent to other planning recommendations that may come out of the MOFFS project. 

 

GRCHydro have undertaken visits and inspections to each village and met with the relevant communities. 

 

Attached for the committee’s reference is the October 2019 Project Management Office report showing the current status and timelines of this project.

 

 

2019-2020 Floodplain Management Program

 

A grant application was submitted for Humula and Mangoplah Flood Studies & Floodplain Risk Management Studies and Plans (FRMS&P).  This application was unsuccessful, and Council will look at what options are available to complete this work in the next few years.

Community Leadership and Collaboration

Objective: We are active community members

Outcome: We recognise we all have a role to play

 

Risk Management Issues for Council

There is a risk that the cost to carry out these projects could be more than was originally estimated. Therefore, Council would need additional funds to complete the works. However, some contingency was built into all the estimates to reduce this risk

Internal / External Consultation

The Office of Environment and Heritage have been heavily consulted throughout the process of planning and executing these projects.

 

NSW Emergency Management is the responsible funding body and receives quarterly status update reports.

 

NSW State Emergency Services and Bureau of Meteorology are consulted when required.

 

Each of these projects is managed using a project steering group made up of members from different areas of Council as per Councils project management methodology.

 

Council officers in various directorates are members of the project steering committees for each project.
