INTRODUCTION The purpose of this document is to provide residents of the Settlement Shores Canal Estates with guidelines on undertaking certain works within the canals. The "canal" is generally described as the area between the revetment walls as shown in APPENDIX A. Works within the canals may involve any of the following:− • Maintenance dredging of canal beds • Rehabilitation of the beach zones • Repair of the revetment walls • Repair of boat ramps, jetties and mooring poles • Construction of boat ramps, jetties and mooring poles • Rehabilitation of rock protection • Repair of stormwater outlets This Guideline applies to all the canals except the new Broadwater & North/South Harbour canal development. 2. REFERENCE DOCUMENTS These guidelines form part of the following overall document set: − • Canal Maintenance Plan (CMP) 2004 • Canal Maintenance Plan − Review of Environmental Factors (REF) 2004 • Resident & Landowner Guidelines 2006 The CMP is a very detailed document which identifies, on an individual property basis, the condition of the existing canals, including the extent of sedimentation, condition of revetment walls, boat ramps, jetties and beach zones. Details of 'illegal' structures and plantings are also listed. The CMP contains a catalogue of photographs for each property as evidence of the condition of the asset. The CMP also provides a detailed table of recommended works and priorities for both Council and private landowners. The REF documents detail the existing environmental, the potential impacts of the proposed maintenance works and the environmental safeguards necessary to undertake the works. The REF and CMP may be obtained from Council on request. 3. RESPONSIBILITIES 3.1 Council The waterway itself is outside the private property boundary and is vested in Council's ownership. Council has accepted responsibility for maintaining the waterways and flood structures (ie flood control weir, stormwater outlets, revetment walls fronting public reserves, rock protection and beach zone up to the property boundary). Resident & Landowners' Guidelines Page 3 Settlement Shores Canal Estate Canal Maintenance 3.2 Landowners A revetment wall is constructed along the length of the canals, with the common boundary of each allotment and the canals, extending to a point 2.1 metres below the revetment wall. The revetment wall forms part of the residential property. A covenant, placed on each property title, states that individual property owners are responsible for the maintenance and repair of the revetment wall. Council encourages all owners to undertake the necessary maintenance work however; council has the power to carry out the necessary maintenance work if a property owner fails to do so. The cost of that maintenance may be charged to the property owner. A second covenant on each of the allotment titles requires there be no buildings, fences, trees or other obstructions within 5.4 metres of the revetment wall in the majority of canals, and 7.9 metres of the revetment wall in the case of The Governors Way. This covenant is required to enable landowners and/or the Council to gain continuous access along the bank adjacent to the waterway for the purpose of removing flood debris, repairing erosion or damage caused by floods or repairing any damage to the canals at the rear of the properties. Council may request property owners to remove obstructions from this zone considered contrary to the covenant. 4. MAINTENANCE WORKS Maintenance works are those works required to return the canal assets to a condition as close as possible to their original condition. Maintenance works are necessary to reinstate the structural, operational and environmental integrity of the canal system infrastructure. A description of the type of maintenance works proposed is shown in APPENDIX B. Specific details of the type of works required adjacent to or within your property may be obtained from the CMP by contacting Council. The CMP also indicates the severity of the problem that may exist with the canal infrastructure adjacent to your property. Resident & Landowners' Guidelines Page 4 Settlement Shores Canal Estate Canal Maintenance 5. MAINTENANCE WORKS BY LAND OWNERS The type of maintenance works required by land owners is described in APPENDIX B. The following steps are to be followed by residents when undertaking maintenance works on the canals:−Step Check with Council about the1 condition of the canal/structure within or adjacent to your property. Step 2 Arrange an inspection of the canal/structure with one of Council's Development Engineers. Step 3 Subject to advice from Council's Development Engineer, you may need to make an application to Council for the proposed works. Note: An engineering design certified by a Civil or Structural Engineer may be required as part of the application for certain structural works eg repair of revetment walls. Council's Development Engineer will advise you about this. Step 4 Council approves the application with or without conditions. Step 5 Arrange for a Council approved contractor to undertake the works. Certain minor works; eg beach replenishment, may be undertaken by landowners under Council supervision. Step 6 Council inspects the works at stages indicated in the approval to the application. Step 7 Major works (eg revetment wall repairs) are to be certified by the contractor as being constructed in accordance with the approved design. Resident & Landowners' Guidelines Page 5 Settlement Shores Canal Estate Canal Maintenance 6. MAINTENANCE WORKS BY COUNCIL Council is responsible for dredging the canals and maintenance of the beach zone 2.1 metres from the revetment walls. Council will also be responsible for maintenance of revetment walls and beach zones fronting public reserves; stormwater pipes and outlets and flood control structures (eg weirs and associated heavy rock armouring). Council will generally undertake maintenance works as follows:−Step Determine the priority of the works to be undertaken considering1 the available funds. Step 2 Determine the need to contract out the works. Step 3 Confirm the method needed to undertake the works. Step 4 Determine the need for detailed engineering design for works. Step 5 Prepare design as required. Step 6 Confirm the proposed works are adequately covered by the REF and modify as required. Step 7 Obtain the necessary licences. eg Rivers & Foreshores Part 3A and Fisheries Management Act Permit/s. Step 8 Advise adjoining residents of the intention to carry out work. Step 9 Carry out works. Step 10 Restore the work areas. 7. DESIGN DETAILS The methods of foreshore maintenance will vary from activity to activity. Advice should initially be obtained from Council to confirm the method of obtaining:− • Site access • Disposal of waste material • Placement of beach zone restoration materials • Sourcing the type of materials needed • Certification of structural works Typical design details for canal profiles, revetment walls, boat ramps and jetties are shown in Error! Reference source not found.. Generally residents will be required to undertake works in accordance with the original approved designs. Any departures from the approved designs are to be designed by a civil or structural engineer and approved by Council. Residents should discuss any departures with Council before engaging consultants to confirm if the departures will be supported. Resident & Landowners' Guidelines Page 6 Settlement Shores Canal Estate Canal Maintenance Notwithstanding the above requirement, improvements should be made to the earliest boat ramp design shown in the original plans. Details of these improvements are outlined below. 8.1 Boating Ramp Improvements It is recommended that timber or concrete edge strips be installed onto new and existing boat ramps to provide a channelling effect to water flowing down the ramp. Alternatively for new boat ramps a dished or concave profile could be constructed. Thirdly, saw−cuts can be placed into existing or new 'flat' boat ramps. Canal Boat Ramp These techniques prevent water from flowing over the sides and creating scour, erosion and undermining the boat ramp. 8.2 Stormwater Outlets Residents are required to control all stormwater from the rear of their properties and direct drainage waters to the legal point of discharge for your property. No stormwater outlets are allowed to discharge water directly to the canals. This form of inappropriate drainage will cause scour and erosion to the beach zones. 9. BOATING FACILITIES Boating facilities are permitted within the canal and include ramps, jetties and mooring poles. The general location and type of facilities permitted are shown in APPENDIX The CMP provide an assessment of the current condition of the existing boating facilities and details may be obtained from Council upon request. It is the landowner's
