cl 2: Am 2012 (57), Sch 2.7 [1].
3   Aim of this plan
The aim of this plan is to protect the environment of the Hawkesbury-Nepean River system by ensuring that the impacts of future land uses are considered in a regional context.
Part 2 General planning considerations, specific planning policies and recommended strategies
4   Application of general planning considerations, specific planning policies and recommended strategies
(1)  The general planning considerations set out in clause 5, and the specific planning policies and related recommended strategies set out in clause 6 which are applicable to the proposed development, must be taken into consideration—
(a)  by a consent authority determining an application for consent to the carrying out of development on land to which this plan applies, and
(b)  by a person, company, public authority or a company State owned corporation proposing to carry out development which does not require development consent.
(2)  Those considerations, policies and strategies should be taken into consideration in the preparation of each environmental planning instrument and development control plan that applies to land to which this plan applies.
5   General planning considerations
The general planning considerations relevant for this Part are—
(a)  the aim of this plan, and
(b)  the strategies listed in the Action Plan of the Hawkesbury-Nepean Environmental Planning Strategy, and
(c)  whether there are any feasible alternatives to the development or other proposal concerned, and
(d)  the relationship between the different impacts of the development or other proposal and the environment, and how those impacts will be addressed and monitored.
6   Specific planning policies and recommended strategies
The specific planning policies and recommended strategies for this plan are as follows—
(1)   Total catchment management
Policy: Total catchment management is to be integrated with environmental planning for the catchment.
Strategies:
(a)  Refer the application or other proposal for comment to the councils of each adjacent or downstream local government area which is likely to suffer a significant adverse environmental effect from the proposal.
(b)  Consider the impact of the development concerned on the catchment.
(c)  Consider the cumulative environmental impact of development proposals on the catchment.
(2)   Environmentally sensitive areas
Policy: The environmental quality of environmentally sensitive areas must be protected and enhanced through careful control of future land use changes and through management and (where necessary) remediation of existing uses.
Note—
Environmentally sensitive areas in the Hawkesbury-Nepean catchment are: the river, riparian land, escarpments and other scenic areas, conservation area subcatchments, national parks and nature reserves, wetlands, other significant floral and faunal habitats and corridors, and known and potential acid sulphate soils.
Strategies:
(a)  Rehabilitate parts of the riverine corridor from which sand, gravel or soil are extracted so that attached aquatic plant beds are replaced and water quality and faunal habitats improved.
(b)  Minimise adverse impacts on water quality, aquatic habitats, riverine vegetation and bank stability.
(c)  Minimise direct and indirect adverse impacts on land reserved or dedicated under the National Parks and Wildlife Act 1974 or the Forestry Act 2012 and conservation area sub-catchments in order to protect water quality and biodiversity.
(d)  Protect wetlands (including upland wetlands) from future development and from the impacts of land use within their catchments.
(e)  Consider the need to include buffer zones (such as adequate fire radiation zones) for proposals on land adjacent to land reserved or dedicated under the National Parks and Wildlife Act 1974 or the Forestry Act 2012.
(f)    (Repealed)
(g)  Consideration should be given to the impact of the development concerned on the water table and the formation of acid sulphate soils.
(h)  New development in conservation area sub-catchments should be located in areas that are already cleared.
(3)   Water quality
Policy: Future development must not prejudice the achievement of the goals of use of the river for primary contact recreation (being recreational activities involving direct water contact, such as swimming) and aquatic ecosystem protection in the river system. If the quality of the receiving waters does not currently allow these uses, the current water quality must be maintained, or improved, so as not to jeopardise the achievement of the goals in the future. When water quality goals are set by the Government these are to be the goals to be achieved under this policy.
Note—
Aquatic ecosystems and primary contact recreation have the same meanings as in the document entitled Australian Water Quality Guidelines for Fresh and Marine Waters, published in 1992 by the Australian and New Zealand Environment and Conservation Council.
Strategies:
(a)  Quantify, and assess the likely impact of, any predicted increase in pollutant loads on receiving waters.
(b)  Consider the need to ensure that water quality goals for primary contact recreation and aquatic ecosystem protection are achieved and monitored.
(c)  Approve development involving primary contact recreation or the withdrawal of water from the river for human contact (not involving water treatment), such as showers, only in locations where water quality is suitable (regardless of water temperature).
(d)  Do not carry out development involving on-site disposal of sewage effluent if it will adversely affect the water quality of the river or groundwater. Have due regard to the nature and size of the site.
(e)  Develop in accordance with the land capability of the site and do not cause land degradation.
(f)  Consider the need for an Erosion and Sediment Control Plan (to be in place at the commencement of development) where the development concerned involves the disturbance of soil.
(g)  Minimise or eliminate point source and diffuse source pollution by the use of best management practices.
(h)  Site and orientate development appropriately to ensure bank stability. Plant appropriate native vegetation along banks of the river and tributaries of the river, but not so as to prevent or inhibit the growth of aquatic plants in the river, and consider the need for a buffer of native vegetation.
(i)  Consider the impact of the removal of water from the river or from groundwater sources associated with the development concerned.
(j)  Protect the habitat of native aquatic plants.
(4)   Water quantity
Policy: Aquatic ecosystems must not be adversely affected by development which changes the flow characteristics of surface or groundwater in the catchment.
Strategies:
(a)  Future development must be consistent with the interim or final river flow objectives that are set for the time being by the Government.
(b)  Ensure the amount of stormwater run-off from a site and the rate at which it leaves the site does not significantly increase as a result of development. Encourage on-site stormwater retention, infiltration and (if appropriate) reuse.
(c)  Consider the need for restricting or controlling development requiring the withdrawal or impoundment of water because of the effect on the total water budget of the river.
(d)  Consider the impact of development on the level and quality of the water table.
(5)   Cultural heritage
Policy: The importance of the river in contributing to the significance of items and places of cultural heritage significance should be recognised, and these items and places should be protected and sensitively managed and, if appropriate, enhanced.
Strategies:
(a)  Encourage development which facilitates the conservation of heritage items if it does not detract from the significance of the items.
(b)  Protect Aboriginal sites and places of significance.
(c)  Consider an Aboriginal site survey where predictive models or current knowledge indicate the potential for Aboriginal sites and the development concerned would involve significant site disturbance.
(d)  Consider the extent to which heritage items (either identified in other environmental planning instruments affecting the subject land or listed in Schedule 2) derive their heritage significance from the river.
(6)   Flora and fauna
Policy: Manage flora and fauna communities so that the diversity of species and genetics within the catchment is conserved and enhanced.
Strategies, generally:
(a)  Conserve and, where appropriate, enhance flora and fauna communities, particularly threatened species, populations and ecological communities, aquatic habitats, wetland flora, rare flora and fauna, riverine flora, flora with heritage value, habitats for indigenous and migratory species of fauna, and existing or potential fauna corridors.
(b)  Locate structures where possible in areas which are already cleared or disturbed instead of clearing or disturbing further land.
(c)  Minimise adverse environmental impacts, protect existing habitat and, where appropriate, restore habitat values by the use of management practices.
(d)  Consider the impact on ecological processes, such as waste assimilation and nutrient cycling.
(e)  Consider the range of flora and fauna inhabiting the site of the development concerned and the surrounding land, including threatened species and migratory species, and the impact of the proposal on the survival of threatened species, populations and ecological communities, both in the short and longer terms.
(f)  Consider the need to provide and manage buffers, adequate fire radiation zones and building setbacks from significant flora and fauna habitat areas.
(g)  Consider the need to control access to flora and fauna habitat areas.
(h)  Consider the need to maintain corridors for fish passage, and protect spawning grounds and gravel beds.
Strategies for wetlands:
(i)  Maintain the ability of wetlands to improve the quality of water entering the river through the filtering of sediments and the absorption of nutrients.
(j)  Maintain the ability of wetlands to stabilise soils and reduce bank erosion.
(k)  Maintain the ability of wetlands to reduce the impact of flooding downstream through the retention of floodwaters.
(l)  Maintain a variety of wetland flora and fauna species in the region and consider the scarcity of particular species on a national basis.
(m)  Encourage the appropriate management of wetlands, including monitoring and weed control.
(n)  Provide opportunities for recreation, scientific research and education where they are compatible with the conservation of wetlands.
(o)  Consider the need to protect and improve the quality and quantity of surface water and groundwater entering wetlands by controlling development in the catchment of wetlands.
(p)  Consider the desirability of protecting any wetlands of local significance which are not included on the map.
(q)  Consider the desirability of protecting or, if necessary, actively managing, constructed wetlands if they have significant conservation values or make a significant contribution to improvements in water quality.
(7)   Riverine scenic quality
Policy: The scenic quality of the riverine corridor must be protected.
Strategies:
(a)  Maintain areas of extensive, prominent or significant vegetation to protect the character of the river.
(b)  Ensure proposed development is consistent with the landscape character as described in the Scenic Quality Study.
(c)  Consider the siting, setback, orientation, size, bulk and scale of and the use of unobtrusive, non-reflective material on any proposed building or work, the need to retain existing vegetation, especially along river banks, slopes visible from the river and its banks and along the skyline, and the need to carry out new planting of trees, and shrubs, particularly locally indigenous plants.
(d)  Consider the need for a buffer between new development and scenic areas of the riverine corridor shown on the map as being of significance beyond the region (which are also scenic areas of significance for the region) or so shown as being of regional significance only.
(e)  Consider the need for controls or conditions to protect those scenic areas.
(f)  Consider opportunities to improve riverine scenic quality.
(8)   Agriculture/aquaculture and fishing
Policy: Agriculture must be planned and managed to minimise adverse environmental impacts and be protected from adverse impacts of other forms of development.
Note—
Refer also to items (1)–(7) and (12) for relevant strategies.
Strategies:
(a)  Give priority to agricultural production in rural zones.
(b)  Ensure zone objectives and minimum lot sizes support the continued agricultural use of Class 1, 2 and 3 Agricultural Land (as defined in the Department of Agriculture’s Agricultural Land Classification Atlas) and of any other rural land that is currently sustaining agricultural production.
(c)  Incorporate effective separation between intensive agriculture and adjoining uses to mitigate noise, odour and visual impacts.
(d)  Protect agricultural sustainability from the adverse impacts of other forms of proposed development.
(e)  Consider the ability of the site to sustain over the long term the development concerned.
(f)  Consider the likely effect of the development concerned on fish breeding grounds, nursery areas, commercial and recreational fishing areas and oyster farming.
(9)   Rural residential development
Policy: Rural residential development should not reduce agricultural sustainability, contribute to urban sprawl, or have adverse environmental impacts (particularly on the water cycle or on flora or fauna).
Note—
Refer also to items (1)–(7) and (12) for relevant strategies.
Strategies:
(a)  Give priority to agricultural production in rural zones.
(b)  When considering a proposal for the rezoning or subdivision of land which will increase the intensity of development of rural land (for example, by increasing cleared or hard surface areas) so that effluent equivalent to that produced by more than 20 people will be generated, consider requiring the preparation of a Total Water Cycle Management Study or Plan.
(c)  Maintain or introduce appropriate separation between rural residential use and agricultural use on the land that is proposed for development.
(d)  Do not locate development in areas identified for future urban purposes in the Metropolitan Strategy.
(e)  Consider the suitability of the land for keeping livestock, whether or not for commercial purposes, and appropriate mitigating measures to prevent land degradation.
(f)  Consider the ability of the land to accommodate on-site effluent disposal in the long term.
(g)  Consider any adverse environmental impacts of infrastructure associated with the development concerned.
(10)   Urban development
Policy: All potential adverse environmental impacts of urban development must be assessed and controlled.
Note—
Refer also to items (1)–(7) and (12) for relevant strategies.
Strategies:
(a)  When considering a proposal for the rezoning or subdivision of land which will increase the intensity of development of that land (for example, by increasing cleared or hard surface areas) so that effluent equivalent to that produced by more than 2,500 people will be generated, consider requiring the preparation of a Total Water Cycle Management Study or Plan.
(b)  Consider urban design options to reduce environmental impacts (such as variable lot sizes and shapes, and the clustering of development).
(11)   Recreation and tourism
Policy: The value of the riverine corridor as a significant recreational and tourist asset must be protected.
Note—
Refer also to items (1)–(7) and (12) for relevant strategies.
Strategies:
(a)  Provide a wide range of recreational opportunities along the river which are consistent with conserving the river’s natural values and character.
(b)  Plan and manage recreational and tourist developments, and associated access points, cycleways and footpaths, so as to minimise any adverse environmental impacts on the river. Locate them where river banks are stable, away from river shallows, major beds of attached aquatic plants or fish breeding areas, where the proposed activities do not conflict with surrounding recreational activities and where significant flora and fauna habitats will not be adversely affected. The upgrading of existing public access to the river is to be preferred over the creation of new access points.
(c)  Minimise conflicts between recreational uses.
(d)  Consider the availability of, or need to provide, land for vehicle parking and for suitable access (including access for cars and buses), for boat service areas and for water, electricity and sewage disposal.
(e)  Consider the environmental impact of ancillary services for recreation and tourist developments, such as amenities blocks and vehicle parking.
(f)  Consider the visual impact of development on the surrounding area.
(12)   Metropolitan strategy
Policy: Development should complement the vision, goal, key principles and action plan of the Metropolitan Strategy.
Strategies:
(a)  Consider the impacts of transport infrastructure proposals on water quality and air quality.
(b)  Consider the impacts of metropolitan waste disposal on water quality.
(c)  Consider the impacts of development on air quality.
(d)  Consider the need for waste avoidance, waste reduction, reuse and recycling measures.
(e)  Consider the implications of predicted climate change on the location of development and its effect on conservation of natural resources.
