3 | 1.0 INTRODUCTION & BRIEF INTERPRETATION | |||||||||||||

4 | ||||||||||||||

5 | The proposed development of the developer's property is designed to meet with the highest environment standards. | |||||||||||||

6 | The proposed development is consistant with the issues listed in the City of Greater Bendigo Planning Scheme Local Provision "21.08 Rural Land Use & Agriculture". | |||||||||||||

7 | There is a direct relationship with the theme of the proposed development and continual decline and lack of conventional agricultural productivity - | |||||||||||||

8 | the current land-use is clearly uneconomic and would require unsustainable capital expense for a single land-holder to achieve and/or maintain an | |||||||||||||

9 | adequate standard of living. The property is clearly outside of the criteria of protection listed in Objectives provided | |||||||||||||

10 | within the Planning Scheme as it is of low to poor agricultural productivity. This assessment is supported by independent reporting sanctioned by the | |||||||||||||

11 | developer. Furthermore the land capability assessment undertaken during this consultancy draws similar conclusions. | |||||||||||||

12 | ||||||||||||||

13 | The developer therefore proposes the following as appropriate responses to the sustainable land-use issues faced by the existing holding: | |||||||||||||

14 | ||||||||||||||

15 | Boundary Realignment - Consolidating and rearranging the existing cadastral boundaries to provide three (new) separate titles | |||||||||||||

16 | allowing multiple dwellings on the site increasing the capital available to develop the sustainable production base. | |||||||||||||

17 | Intensive Agroforestry Systems - A wholistic approach to the development of the proposed individual holdings. Though capital intensive - the development | |||||||||||||

18 | of such systems will provide a base of sustainable short to long term production whilst achieving the land protection objectives consistant with | |||||||||||||

19 | the Planning Scheme and North Central Catchment Management Authority Regional Catchment Strategy. Areas selected and fenced for grazing according | |||||||||||||

20 | to land classification assessment (syn. Land Classing) and established with suitable Fodder and Timber species with extensive pasture renovation including capital | |||||||||||||

21 | remineralisation works and resowing to productive perennial pastures. | |||||||||||||

22 | Riparian Protection and Revegetation - Livestock exclusion fencing of all drainage depressions with appropriate revegetation works - stock water | |||||||||||||

23 | to be provided by reticulated system of water troughs - removing stock access to earthen water storages (e.g. Dams and Springs). Contructed wetland construction is also | |||||||||||||

24 | proposed to provide localised and whole catchment environmental services in the areas of nutrient and sediment control and habitat provision. Furthermore new water storages | |||||||||||||

25 | proposed are intended to balance onsite production needs with catchment protection. The generally small storage volumes of these proposed | |||||||||||||

26 | dams is intended to reduce flood velocity, whilst maintain adequate downstream flows. | |||||||||||||

27 | Intensive Forestry Systems - Establishment of mixed species high value forest plantations in areas of low agricultural productivity. Managed using selective harvesting | |||||||||||||

28 | (as opposed to clearfelling) techniques, these systems will be examples of appropriate land-use and land protection whilst providing a range of low to high value sources | |||||||||||||

29 | of forest products - i.e. Environmental Services, Farm Timber Products, Cabinet Timbers & Seed. | |||||||||||||

30 | Farm Stay/Bed & Breakfast - The proposed three (3) new properties have provision for the development of individual separate dwellings | |||||||||||||

31 | to contribute to the income stream through accommodation services. These buildings would also provide accomodation to farm labour as required during different times | |||||||||||||

32 | of the farms' production cycles. The production systems designed are labour-intensive and as such will require outside labour to maintain adequate production standards. | |||||||||||||

33 | Intensive Garden Agriculture - The establishment of substantial intentionally designed food gardens in the respective building envelopes is intended to replace outside | |||||||||||||

34 | expenditure on food - thereby forming a significant internal source of income - a quantum departure from the prevailing economic conditions encountered on most broadacre | |||||||||||||

35 | properties where generally only a small amount of food consumed on the farm is produced in situ. | |||||||||||||

36 | ||||||||||||||

119 | Building Envelope Water Storage/ | Dwelling to have 1 x 120KL ferrocement tank storing roof catchment - to be reticulated to house | ||||||||||||

120 | Reticulation Systems | for domestic use. Additional 22000 litre RC tank (WT2) is to be placed at | ||||||||||||

121 | the house (2.5m fall to house). Water from this tank is to be used for fire water supply and back up supply for the dwelling. | |||||||||||||

122 | A small 1000 litre tank is proposed for the Garden/Chook Shed to supply chickens. A reticulation system | |||||||||||||

123 | is proposed to deliver water as required to gardens and for fire water supply from dam storage. | |||||||||||||

124 | Fire Systems | Fire control and prevention systems are built into the overall design of the property. As is required | ||||||||||||

125 | the installation of CFA-approved tank fittings will be fitted to all water tanks excepting the garden shed's. | |||||||||||||

126 | Management of the property wil provide the simplest means of reducing the risk of fire to the property. | |||||||||||||

127 | Ensuring the timely seasonal grazing/slashing takes place in all sectors of the property will be the | |||||||||||||

128 | main tool in reducing this risk. | |||||||||||||

134 | as to the respective area land capabilities which are assessed following the required criteria outlined in | |||||||||||||

135 | A Land Capability Study of the City of Greater Bendigo, Strathfieldsaye District. | |||||||||||||

136 | Additional Water Storage | Currently there is 1 x 4Ml gully embankment dam (ref to site plan). | ||||||||||||

137 | Internal Roading/Access | No internal roading exists at this stage. A single all weather access road is proposed to enter from Shanahans Rd | ||||||||||||

138 | Where slopes exceed 5% along the route of the access lane cut-off drains are proposed to | |||||||||||||

139 | reduce run-off velocities at 20m intervals. | |||||||||||||

140 | Access & Availability to Utilities | Overhead Powercor supply lines are installed through the site and is already connected at the shed. | ||||||||||||

141 | Telephone has been previously connected to the shed. | |||||||||||||

142 | Coliban Water/Sewerage reticulation, or Kinetik gas supply lines are not available to the property, nor likely | |||||||||||||

143 | to be in the foreseeable future. Gas will be supplied by delivery in bottles as required for domestic use only. | |||||||||||||

144 | Impacts on adjoining land | The property currently has little impact on adjoining land with the only observed impact being some | ||||||||||||

145 | minor nutrient and sediment loadings from overland runoff and through the soil. The proposed | |||||||||||||

146 | development would limit these loadings further by virtue of improved nutrient cycling and water use. | |||||||||||||

147 | Visually the proposed development is designed to be consistant with the area, although more advanced | |||||||||||||

148 | in its application. Extensive Shelter Screening, Contoured Treelines and appropriate revegetation works complete | |||||||||||||

149 | an aesthetically pleasing package. | |||||||||||||

150 | Effluent Disposal | Given the Land Capability issues related to the proposed siting of the main building envelope it is | ||||||||||||

151 | recommended that a solid state EPA approved effluent disposal system be installed. This system will be | |||||||||||||

152 | of a RotaLooOnZite Wormfarm treatment system. Treated effluent water will be reticulated via a underground | |||||||||||||

153 | irrigation pipe system to building envelope shelter systems. | |||||||||||||

154 | External Roads & Traffic Movement | The property is a corner block with the eastern boundary fronting Mills Rd (bitumen) and the western boundary | ||||||||||||

155 | fronting Shanahans Rd (gravel). The proposed property entrance is to come off the western end of the | |||||||||||||

156 | Shanahans Rd face of the property. Vision of oncoming traffic is satisfactory at this exit. | |||||||||||||

157 | As is appropriate the landholders' propose to enhance the roadsides stability and flora and fauna values as such improving | |||||||||||||

158 | on its Medium Conservation Value - Local Road classification in the COGBgo Roadside Management Guidelines. | |||||||||||||
