The creation of the Urban Edge was identified as a mechanism to protect significant environments and resources and contain urban sprawl, in order to rationalise service delivery through managing growth and densification. The subsequent adoption of the MSDF and the policies contained therein endorsed the need for an Urban Edge that defines an outer limit to urban development. Towards the end of 1997, the Cape Metropolitan Council (CMC) appointed three consultants to prepare edge studies for distinct sections of the metropolitan area: Peninsula, Northern and Helderberg. The Urban Edge was drafted based on a contextual analysis of the area and the synthesis of the following edge informants: • • • • • • • • • Geophysical environment Biophysical and ecological environment River and wetlands systems Infrastructure location and capacity Land use and related patterns Demographic and population profiles and trends Legal, planning and land ownership situation Socio-cultural and historic environment Visual resource analysis. Extensive consultation was undertaken in order to reach agreement on the alignment of the Urban Edge Line and input received from interested and affected parties on the proposed boundary was used to amend and refine the proposed Urban Edge Line. On the basis of an agreed Urban Edge, supportive policies and strategies were drafted in order to manage the Urban Edge and immediate surrounds on a sustainable basis. However, in the case of the Peninsula Urban Edge, due to the complex nature of the area detailed management zones and associated area specific management guidelines were not identified. The Urban Edge Studies also identified the need for a more localised approach to the sustainable management of the Urban Edge Line and the zone immediately adjacent. The Urban Edge Studies were adopted as policy by the City of Cape Town on 29 August 2001 and subsequently submitted to the Provincial Government of the Western Cape for approval as Structure Plans in terms of Section 4(6) of the Land Use Planning Ordinance. However, due to wider structure planning issues, the City of Cape Town Urban Edge Structure Plan approval has not been granted to date. In addition, following the veldfires of 2000, the Ukuvuka campaign was launched. In April 2001, the Ukuvuka Natural Interface Study, Phase 1 report was completed which was followed by the appointment of consultants to undertake the Phase 2 work. The Phase 2 work comprised two studies, Stormwater Management on Slopes Adjacent to Natural Areas (completed in 2003) and Veldfire Related Planning Guidelines. The Veldfire Related Planning Guidelines document was completed in April 2004 and clearly has a close relationship with the Urban Edge Guidelines Manual. The Veldfire Related Planning Guidelines document is contained in Annexure 6 of this document. 1.2 DEVELOPMENT APPLICATIONS ADJACENT TO THE URBAN EDGE Most of the development applications received by the local authority are straightforward and the decision-making in that regard intuitive. However, there are a fraction of applications received that are controversial and require careful consideration. Undoubtedly, the greatest pressure for development occurs in the management zone adjacent to the Urban Edge. These applications are therefore often difficult and controversial, with MLH Architects and Planners in association with Piet Louw Architects, Urban Designer, Planner 1 URBAN EDGE GUIDELINES MANUAL arguments both for and against the proposed development equally convincing. As a result, the decision-making process associated with the assessment of such development applications needs to deal with the complexity within the local context. Development applications are often necessarily motivated on the basis of interpretation of applicable policy documentation. However, the metropolitan-wide policy documents often use all-encompassing principles, summed up in catch-phrase jargon (e.g. densification), which can be twisted and used to substantiate any manner of development application – whether suitable or not. It then becomes extremely difficult to assess what constitutes “good” versus “bad” development since the broad principles have been shown to support the proposed development application. Although the overarching principles apply at a metropolitan scale, these need to be contextually interpreted and applied to the specific local situation. For example, although exercise is universally accepted to be good for human health, too much exercise, or exercise in certain circumstances (e.g. during illness) may in fact be harmful and destructive. Thus, although a generally accepted principle, it cannot be applied as a prescriptive standard for each individual in their unique situation. As a result of the inherent ambiguity in interpretation of the metropolitanwide principles, the amendment of the Urban Edge is often used in support of the specific development application. However, as indicated above, it is critically important that each application is evaluated on its own merits and in terms of the specific local context. Within the framework provided by the policy documents, the assessment in terms of the local context should be first and foremost. The amendment or refinement of the Urban Edge, if at all, should be incidental to and as a consequence of the assessment of the specific development application. The previous Studies, referred to above, defined the Urban Edge boundary and to some extent, the management zone on either side thereof. Due to the vast area transected by the Urban Edge (in excess of 300km), the Edge was based on a macro assessment of issues, but defined at a micro scale along cadastral boundaries. The guidelines are therefore focussed on translating the macro-principles as contained in the Urban Edge Studies into a micro-level context where they can be applied to the assessment of development applications adjacent to the Urban Edge. Thus, the Urban Edge Guidelines Manual uses the accepted and adopted Urban Edge boundary as a starting point, but provides the framework within which decisions regarding local development applications can be made. It is recognised that in hindsight, some sections of the existing Urban Edge may seem illogical. It is important to stress that it is NOT the purpose of the guidelines manual to revisit or redefine the accepted Urban Edge. Rather, the guidelines manual operates within the context of the current documentation and provides a decision-support system for use at a local level which serves to achieve a level of consistency in decision-making throughout the Unicity. Similarly, the purpose of this research and documentation is NOT to produce a comprehensive analysis of the micro-scale conditions associated with each erf along the Urban Edge. Such refinement will be the result of the future assessment of individual development applications where the micro-specific conditions may adjust the Urban Edge – either restricting or increasing the line around the urban area. For instance, cadastral boundaries do not always respect topographic constraints such as steep slopes that, in reality, may redefine the effective Urban Edge in terms of a particular application. 1.4 1.3 HOW TO USE THE GUIDELINES MANUAL PURPOSE OF THE URBAN EDGE GUIDELINES MANUAL The need for guidelines supporting the Urban Edge Studies was identified by Local Authority officials who are faced with the assessment of development applications adjacent to the Urban Edge. The purpose of the manual is therefore the provision of a decision-making framework that allows the planning officials to review, evaluate and approve or reject various development applications. The Guidelines Manual is intended for officials within the Local Authority who review and assess development applications adjacent to the Urban Edge. It is intended to assist with difficult applications in order to ensure that all the necessary elements have been covered in the assessment, and that there is consistency in decision making. MLH Architects and Planners in association with Piet Louw Architects, Urban Designer, Planner 2 URBAN EDGE GUIDELINES MANUAL It is recognised that the bureaucratic procedures associated with the assessment of development applications may change over time. However, instead of focusing on providing an additional procedure for the officials, the Guidelines Manual provides a decision-making support system that sets out the thought process that the planner should consider, irrespective of the bureaucratic procedure that is stipulated at the time. In this regard, the planner needs to be familiar with the normative position that underpins the Guidelines Manual (Chapter 3) (The normative position being the accepted standard and position to which we all subscribe). The normative position then provides the point of reference for the more detailed evaluation that focuses on the specific local context of the site in question. The decision-support system is explained in Chapter 4 and Annexure 1. It comprises a two-fold evaluation: a sensitivity analysis in terms of the normative position, followed by a more detailed evaluation in terms of the specific context and characteristics of the site. The Guidelines Manual is also intended to assist the applicant with the submission of applications. As such, the Guidelines Manual provides the normative position against which all applications will be tested through the sensitivity analysis. Secondly, the Guidelines Manual contains Urban Edge forms (Annexure 2 – 5) which provide detailed step by step guidance, and which can be completed by the applicant in addition to the motivation report. These forms indicate the policy and legal documents that should be considered by the applicant prior to submission, thereby ensuring that the applicant has made reference to all the necessary secondary documentation. It is important to understand that the requirement for the applicant to complete the relevant form is entirely at the discretion of the Local Authority, and will be largely dependent on the nature and location of the property in question as well as the nature of the proposal. MLH Architects and Planners in association with Piet Louw Architects, Urban Designer, Planner 3 URBAN EDGE GUIDELINES MANUAL CHAPTER 2: ASSUMPTIONS At the outset it is necessary to record the assumptions that underpin the rationale behind the Guidelines Manual and therefore guide the structuring thereof in order to provide a useful tool for the assessment of development applications adjacent to the Urban Edge. These assumptions or points of departure are discussed in the sections below. 2.1 LEGITIMACY OF PREVIOUS DOCUMENTATION The Guidelines Manual accepts the rationale and theoretical bases as contained in the preceding documentation adopted as policy by the City of Cape Town. Therefore, the principles of development and spatial guidelines as contained in Metropolitan Spatial Development Framework and the points of departure and terminology of the Urban Edge Studies are accepted. Similarly, the Urban Edge as determined by the edge informants and an extensive public participation process, and subsequently adopted as policy provides a fix for the purpose of the Guidelines Manual. However, since the Urban Edge was prepared at a metropolitan-scale and based on cadastral boundaries, it is recognised that there is scope to refine the Urban Edge through an interpolation process based on assessment of individual applications in their specific local context. In this regard, the Urban Edge is considered a starting point for the purposes of the Guidelines Manual, but is not immovable as a result of development applications. The Urban Edge may or may not be refined based on the specific local context and nature of the development application. As the Urban Edge is refined through the various applications, so the arguments and principles underpinning the definition of the Urban Edge line are tested and become stronger. The defence of the modified Urban Edge in future applications therefore becomes easier. 2.2 TERMINOLOGY The Urban Edge Studies defined the notion of an Urban Edge, Urban Reserve and Management Zones. The interpretation of this terminology is accepted and used in the Guidelines Manual. However, none of the previous documentation has defined what constitutes urban or rural development, primarily because of the complexities associated therewith. Urban development cannot be simply defined based on land use or the nature of the built form. It can be argued that the unique context determines whether development is considered to be urban or not. The context includes the specific local environment, site size and scale of development, vegetation, surrounding land uses and nature of built form, which is why “urban development” is difficult to define in a single sentence. The definition of “rural development” suffers from similar complexities. Therefore, the distinction between urban characteristics and rural characteristics cannot be neatly made. Rather, rural and urban form the two ends of a continuum. Some developments display clearly urban characteristics and other clearly rural characteristics and should therefore be inside and outside the Urban Edge respectively. Other developments, on the other hand, display both urban and rural characteristics, which makes it critical to examine the developed footprint and the specific context within which the development falls. It can be argued that the definition of whether an activity or development is urban or not is incidental to the evaluation of the specific development application. Since each application is unique, it should therefore be assessed firstly within its specific context to determine whether the proposed development is appropriate or not. It is only once this decision has been made, that the debate can be entered into about whether the Urban Edge line needs to be adjusted in a refined alignment as a consequence. 2.3 MECHANISM TO ASSIST DECISION-MAKING The Guidelines Manual is not intended to provide a blueprint for assessing development applications on the Urban Edge because in many instances, the answers are not simple. As indicated above, the unique context specific to each application needs to be understood. The purpose of the Guidelines Manual, therefore, is to provide a tool that will assist the decision-making process associated with the assessment of development applications adjacent to the Urban Edge, and should be read in conjunction with the respective area–specific Urban Edge Report (2001), and in the case of the Peninsula, also the Peninsula Management Zone Report. MLH Architects and Planners in association with Piet Louw Architects, Urban Designer, Planner 4 URBAN EDGE GUIDELINES MANUAL The decision support framework assumes that the local authority officials who are responsible for assessing the applications are familiar with and have an intimate working knowledge of the relevant planning policies applicable to the local area. The officials are therefore well placed to assess whether the interpretation and application of the macro-scale policy, as motivated by the applicant, is realistic, and through a series of prompt questions to evaluate the overall implications of the development proposal and to formulate suitable conditions should the application be approved. 2.4 TRANSPARENCY To the extent that LUPO and the Environmental Conservation Act requires, the decision-making process is transparent. On the basis of this, and that the Guidelines Manual is aimed at the larger and the more controversial edge related land use applications, the manual should be publicly available to ensure that applications are sufficiently and correctly motivated. If the criteria and considerations used to evaluate the development applications are public knowledge, the application process can be shortened since at the outset the applicant can provide sufficient and adequate information. The local authority officials can therefore quickly review the information provided on the appropriate form (See Annexures 2-5) to ensure that it is adequate and that the applicable documentation has been consulted and referenced. Sustainable development requires co-ordination between developers and officials – not only in terms of submission of applications, but also ongoing management of development and the resultant Urban Edge boundary requires a cooperative working relationship between the public and private sectors. MLH Architects and Planners in association with Piet Louw Architects, Urban Designer, Planner 5 URBAN EDGE GUIDELINES MANUAL CHAPTER 3: NORMATIVE POSITION A normative position underpins the Urban Edge Guidelines. It is necessary to understand this position as it establishes the premises and principles upon which the decision-support system (as detailed in Annexure 1) is developed. Any normative position is value-laden. It presents what ought to be, and it represents the generally acknowledged and accepted position of the majority. Previous Urban Edge studies cite McHarg, Mumford, Norberg-Schultz and Lynch as visionaries who contributed to the rationale for managing the outward growth of a city. This is based on the premise that the natural environment is recognised as important. This provides the basis for the formulation of the normative position that will be used to support the Guidelines Manual. The Urban Edge, as established in the previous studies and defined according to select cadastral boundaries and contour levels is accepted as the starting point for the Guidelines Manual. However, the Urban Edge, and the Guidelines both may be refined over time, based on the piecemeal assessment of individual applications and a monitoring of the effects of those decisions. Of concern regarding the current alignment of the Urban Edge is that often neither the natural environment (e.g. water, fauna, etc) nor the visual environment (e.g. public views, scenic drives) necessarily coincide with cadastral boundaries or contour levels. The process by which development applications are reviewed should provide an opportunity to clarify and consolidate the built edge of the city, in a variety of forms, and to let the natural or unbuilt condition be the positive, and the primary informant for such decision-making. The guidelines in this manual place a strong emphasis on the natural informants dictating the resultant form of development. In this regard, ecological and visual continuities can be achieved and enhanced. The resultant built form can then be used to define the Edge, not necessarily coinciding with the current Urban Edge, but providing a refinement thereto. The normative position promotes the fundamental principles and values upon which guidelines are framed. These are: the need to acknowledge and promote the unique and different environmental and built character and qualities of Cape Town and the need to create sustainability. The guidelines draw on these principles and apply them to the assessment of individual development applications. By its very nature, decision-making regarding the development applications is reactive rather than pro-active. However, it is still necessary to ensure that the resultant urban form serves the greater public good. In this regard, it is also critical to ensure that the cumulative effect of the incremental growth and development does not negatively impact on either the uniqueness of the metropole or the sustainability thereof. It should, in fact, enhance and promote uniqueness, while contributing to the definition of the built edge through an appropriate built form. In order to practically apply thes e principles to the decision-making framework, a balanced approach to development needs to be adopted. In other words, it is important to recognise that sustainable living requires a balanced and harmonious interaction of the following four components or environments: • • • • Biophysical – living organisms and associated life support systems (air, water, soil, etc) which provides the basis to our existence. Social – people living together such that there is a peaceful coexistence Economic – jobs and money which fuel development Institutional – power, policy and decision-making which expresses itself in democracy The determination of the Urban Edge was seen as a mechanism to manage growth and development pressures within Cape Town by protecting significant environments and resources and containing urban sprawl in order to rationalise service delivery through managing growth and densification. The uniqueness of Cape Town is defined by the integration of and interrelationship between a number of informants or criteria, each exhibiting an inherent value. It should be noted that celebrating uniqueness does not equate to resisting change, but rather to ensuring that special places are protected and enhanced and new ones created. MLH Architects and Planners in association with Piet Louw Architects, Urban Designer, Planner 6 URBAN EDGE GUIDELINES MANUAL Fig 1 sets out the working method that has been adopted in order to unfold and graphically illustrate the individual informants and combinations thereof. Fig 2 sketches the broader context of the Metropolitan Area of the City of Cape Town to illustrate the relationships between the dominant natural elements, the City of Cape Town Boundary, the Urban Edge, the main national routes to and from the City and the urban footprint or built-up area with the distribution of urban centres. The main point illustrated in Fig 3a relates to the informal nature and general looseness of the edge of the current urban built-up footprint that is outward orientated. However, the establishment of protected areas has created a first layer of constraint to urban expansion. Fig 3b. identifies the Urban Edge line which follows cadastral boundaries. The subsequent sequence of figures(3c-h), all informants in their own right, contribute to the totality of the Green Structure (Fig 3i). The individual layers of informants are: • • • • • • Fig 3c Fig 3d Fig 3e Fig 3f Fig 3g Fig 3h Prominent Landform and Character Areas Valuable soils Hydrology: Above and Below Ground Water Resources Aquatic Ecological Resources Terrestrial Significance Protected Areas and Core Flora Conservation Sites More design orientated informants are illustrated on Fig 3j namely Landmark Elements and Special Places, and on Fig 3k which shows Scenic Routes and Significant Public Views. Figures 3i, 3j and 3k combine to form Fig. 4 reflecting the Composite Resources and Character Contributing Elements. The natural informants provide the starting point for the unique qualities of Cape Town. It is the combination of prominent landform, soils, aspect and water (both surface and groundwater) that shape the landscape and create conditions for particular micro-climates and the establishment of various species of flora and the supporting fauna. Over time, however, modifications were introduced to the natural landscape, which have resulted in scenic routes and views, a specific pattern of agriculture, and a unique cultural and historical landscape. The combinations and interrelationships of these informants create the character and uniqueness of Cape Town at a macro-scale. It is therefore these criteria and informants from both the natural and modified landscapes that need to underpin and guide the decision-making process. 3.1 THE URBAN EDGE LINE AND THE BUILT EDGE CONCEPT The opportunity exists, and it is argued that it is absolutely paramount, to clarify and consolidate the built edge of the city. This can occur in a variety of forms, however the overarching intention should be the establishment and creation of a clearly defined edge which recognises the informants and their contributions to the totality of the “green” system. The objective is to work towards a situation where the natural condition is the positive end state. To achieve this end, it is important to know where not to develop and where to promote continuities to the maximum degree possible to ensure common agreements about regionally significant linkages (linking coast to coast, coast to mountain zones), ecological corridors and public viewing experiences. Furthermore, the edge should be made in a strong coherent way, using built form through the gradual piece-meal refinement of the edge, effectively finishing-off the built-up area in the form of a Built Edge Line. This line does not necessarily follow the Urban Edge, although it could coincide with it (as occurs along much of the Peninsula Urban Edge in the City Bowl and along the Atlantic Seaboard). In many instances, the Built Edge Line will fall inside the currently defined Urban Edge line. From a legibility point of view, this approach should clarify where the city (built-up area) stops and starts using the Built Edge as the device to create a clear edge, and through this defining the extent of the natural domain. MLH Architects and Planners in association with Piet Louw Architects, Urban Designer, Planner 7 URBAN EDGE GUIDELINES MANUAL The unbuilt zone between the future Built Edge Line and the current Urban Edge can accommodate and include public open space, ecological and river corridors, private open space, playing fields, agricultural activities and uses, rural elements such as treed avenues, vineyards, orchards, fields homesteads and farmsteads, and rural activities associated with the cultivation of the land. 3.2 THE BUILT EDGE CONCEPT APPLIED The concept discussed above is applied to the metropolitan context in Fig 6. It is an illustration at the level of principle and intent. Built form is used in a variety of ways to create a clear, defined edge. At the junction of the built edge line, and national and scenic routes, “gateways” and sense of arrival-type spaces should be created. The built edge should, to the maximum degree possible, be aligned to enable scenic routes to experience a feeling of openness and greenness. In addition, the built edge should not present the rear and/or sides of developments onto scenic routes, rather fronts with public access routes and associated landscaping.

Irrespective of the bureaucratic paper-trail required in the assessment of development applications, which will undoubtedly change over time, the officials from the local authority are required to assess development applications and provide recommendations to politicians who make the final decision. The decision-support system presented in the Guidelines Manual read together with the specific Veldfire Related Planning Guidelines (see Annexure 6) is intended to assist the officials (particularly the planners) in making decisions regarding development applications adjacent to the Urban Edge and to provide consistency in this decision making throughout the Unicity. This document is intended to assist the planner to undertake a sensitivity analysis of the application, focussing specifically on where the site is in relation to the Urban Edge. The sensitivity analysis is based on the application of the principles embodied in the normative position. Through a series of prompt questions and suggestions, the planner can quickly ascertain the extent to which the development application contributes towards or threatens the uniqueness of the area and the ongoing sustainability thereof. In terms of the heightened sensitivity, the planner is then well placed to evaluate the development application in more detail, in terms of the specific characteristics of the site and the proposed built form. A further set of prompts and comments is provided for the detailed evaluation. With the background of the sensitivity analysis, the planner evaluates the application with specific reference to how the applicant has applied the relevant policy and legislative documentation in the motivation of the proposed development. The detailed evaluation should occur in two parts: The first to determine whether the application is consistent with existing policy, and the second part to determine whether the proposed built form responds adequately to the specific characteristics applicable to the site. On the basis of an overall evaluation for each section, the planner is then well placed to provide a recommendation from a planning perspective. MLH Architects and Planners in association with Piet Louw Architects, Urban Designer, Planner 17 URBAN EDGE GUIDELINES MANUAL 4.2 SENSITIVITY ANALYSIS: COMPATIBILITY WITH NORMATIVE PRINCIPLES On receipt of the completed application, the planner for the area can first conduct a sensitivity analysis in the context of the normative position to indicate the nature of the Urban Edge environment within which the application is based, and the associated issues that will require careful consideration. At a fundamental level, the proposed development should comply with principles encompassing the normative position. In order to assist the planner to assess whether this is indeed the case, the following prompt questions and suggestions for a preliminary evaluation have been compiled. In this section, the considerations relating to the normative principles focus specifically on where the site is located in relation to the informants that contribute to the quality and character of the Cape Metropole and contribute to the sustainability thereof. It is critical that these fundamental principles are adhered to, regardless of the type of development proposed. A more detailed evaluation relating specifically to the proposed development occurs at a later stage (section 4.3) and focuses on the characteristics of the site and the anticipated built form response. In addition, this detailed evaluation must take into account the Veldfire Related Planning Guidelines contained in Annexure 6 of this document. Therefore, the sensitivity analysis is not intended to provide absolute answers to whether the development should be permitted or not, but rather to heighten the awareness of the planner to the sensitive issues as emerging from the normative position that should be borne in mind when undetaking the detailed evaluation. MLH Architects and Planners in association with Piet Louw Architects, Urban Designer, Planner 18 URBAN EDGE GUIDELINES MANUAL CONSIDERATIONS A. GENERAL CONSIDERATIONS A1 To what extent is the proposed development desirable from a public benefit and desirability perspective? COMMENTS / SUGGESTIONS • While it is important that development is socially responsible and stimulates equitable economic development, it should also be environmentally sound. It can be expected that the personal economic gain from the proposed development will be argued in terms of the benefits to society as a whole (e.g. increase in employment opportunities, increased rates for the local authority). The benefit of the proposed development to the broader public should be quantified (direct, indirect, recurrent and cumulative benefits) wherever possible in order to measure the public benefit against the anticipated costs. MLH Architects and Planners in association with Piet Louw Architects, Urban Designer, Planner 19 URBAN EDGE GUIDELINES MANUAL CONSIDERATIONS A2 To what extent does the proposed developed impose additional costs to Council and society? • COMMENTS / SUGGESTIONS While it is important that development is socially responsible and stimulates equitable economic development, it should also be environmentally sound. The various costs (although often not expressible in monetary terms) need to be assessed in this regard. However, the direct costs associated with the provision of infrastructural services, and the indirect costs incurred through the enforcement of conditions needs to be examined. In addition, the opportunity cost to society also needs to be evaluated (e.g. loss of land with high agricultural potential, additional impact on infrastructural services). These issues and the initial, recurrent and cumulative effect thereof should be weighed against the purported benefits of the proposed development. Additional conditions (financial or infrastructural) may need to be imposed should the costs justify it. MLH Architects and Planners in association with Piet Louw Architects, Urban Designer, Planner 20 URBAN EDGE GUIDELINES MANUAL CONSIDERATIONS A3 To what extent does the public comment received support the proposed development? A4 To what extent do the comments from other departments support the proposed development? • • COMMENTS / SUGGESTIONS The planner is responsible for making the overall decision with regard to the application for the proposed development. However, since sustainability requires accountability, participation and transparency, the public comments need to be recognised, and where valid, feasible and enforceable conditions should be stipulated, particularly those that protect the broader public interest, rather than localised self interest. The planner is responsible for making the overall decision with regard to the application for the proposed development. However, since sustainability requires accountability, participation and transparency, the comments from other departments need to be recognised, and feasible and enforceable conditions should be prescribed. In particular, special consideration should be given to the legal requirements in terms of the Environmental Conservation Act and the Heritage Resources Act. MLH Architects and Planners in association with Piet Louw Architects, Urban Designer, Planner 21 URBAN EDGE GUIDELINES MANUAL CONSIDERATIONS A5 To what extent is the site visually exposed? To what extent is the site located in a hazardous position from a veldfire perspective. • • • COMMENTS/SUGGESTIONS Special care needs to be taken when sites are located on high elevational ground, ridgelines or on ground with slopes greater than 9° since it is likely to be visually sensitive. In this regard, it is important to determine the areas from where it can be viewed (of topography and aspect). Particular attention should be given to sites where development may impact on the silhouette of the skyline and/or the ridgeline, and where visible from gateways to the city, recognised metropolitan viewpoints of public significance and scenic routes. 9° is an internationally recognised convention. Development on slopes of 9° or steeper is likely to have a visual impact. Note Annexure 6, Section 8.1 and Figure 7. MLH Architects and Planners in association with Piet Louw Architects, Urban Designer, Planner 22 URBAN EDGE GUIDELINES MANUAL CONSIDERATIONS A6 To what extent can the site contribute to the continuity and sustainability of aquatic and terrestrial ecological corridors? • • A7 To what extent is the site located in proximity to protected or productive land? • • COMMENTS/SUGGESTIONS Consideration needs to be given to the proximity of the site to the coast and/or stream or aquifer networks. Coastal erosion, rising water levels and floodlines should be taken into account. In addition, the nature of the fauna and flora on the site (in terms of sensitivity and rarity) should guide the permissible development. It is critical that sensitive and rare biomes are not isolated, but that they form part of a wider network where natural migration is not inhibited. Where applicable, ensure the principles of the “Asset Protection Zone” and “Final Modification” as contained in Annexure 6 are adopted. Development adjacent to high potential agricultural soils or protected natural environments (formal or informal) should be sensitively approached. As far as possible, good agricultural land should be retained for such use and therefore developments adjacent thereto should be compatible with agricultural land use. Similarly, land use in close proximity to protected environments should support, enhance and possibly expand the inherent uniqueness thereof. Where applicable, ensure the principles of the “Asset Protection Zone” and “Final Modification” as contained in Annexure 6 are adopted. MLH Architects and Planners in association with Piet Louw Architects, Urban Designer, Planner 23 URBAN EDGE GUIDELINES MANUAL CONSIDERATIONS A8 To what extent is the site located along a scenic route, in the vicinity of landmark features, near gateways or adjacent to prominent public viewpoints? A9 To what extent is the site located in proximity to special places or significant elements? • • COMMENTS/SUGGESTIONS Views onto the site from scenic routes and prominent public view points are to be considered. It is essential that sites that are implicated in this regard are sensitively designed, with particular attention given to issues such as building grain, building massing, roof silhouette, boundary details and foreground. Special places and elements such as neks (e.g. Constantia Nek, Kloofnek), tree avenues of stature, and places of historical, heritage and public significance, and where these contribute to the ‘cultural landscape’, define the character and uniqueness of an area. The urban design for the site should therefore respond accordingly, recognising and celebrating the uniqueness encapsulated in the place-making elements. MLH Architects and Planners in association with Piet Louw Architects, Urban Designer, Planner 24 URBAN EDGE GUIDELINES MANUAL CONSIDERATIONS A10 To what extent is the site in close proximity to green structures (e.g. MOSS, zones or areas with extensive tree canopies)? To what extend is the green structure a potential veldfire hazard? • • • • COMMENTS/SUGGESTIONS When a site is adjacent to a “green corridor”, it is important that the development responds appropriately, and where possible, contributes towards and expands the green structure. Particular attention in this regard should be given to landscaping and the nature and location of the built footprint. Apply the veldfire related planning guidelines if necessary (Annexure 6). The overall intention is to maximise the open space, as either public or private open space, and to concentrate the built footprint and its impact. Apply the veldfire related planning guidelines if necessary (Annexure 6). MLH Architects and Planners in association with Piet Louw Architects, Urban Designer, Planner 25 URBAN EDGE GUIDELINES MANUAL 4.3 DETAILED EVALUATION BY PLANNER The type of application (rezoning, subdivision etc.) and sensitivity analysis provide the backdrop to the more detailed evaluation presented below. In particular, the sensitivity analysis should indicate to the planner the issues that require special attention when considering the characteristics of the specific site and the proposed built form response, including the response of the application to the Veldfire Related Planning Guidelines. (Annexure 6). In order to synthesise the arguments presented in the supporting motivation and assist with the decision-making process, the detailed evaluation is comprised of prompt questions (considerations) and suggestions. The sections are arranged in the same format as the Urban Edge form (See Annexures 2-5) that should be completed by the applicant. However, in order to assist the planner with the integration of the information presented, a limited number of overarching questions with supporting comments are provided for each section. It is not possible to anticipate and provide a definitive answer for every type of situation that may arise. Therefore, the questioning technique applied in the considerations column is formulated to stimulate the thought process or further discussion. Similarly, the illustrations are included to support the comments or suggestions and as such, indicate generic situations, the principles of which will need to be applied to the specific circumstances pertaining to the development application in question. It is anticipated that the responses to the considerations and suggestions will enable the planner to formulate an opinion on whether the proposed development should be approved, and if so, the conditions that should accompany the final decision. MLH Architects and Planners in association with Piet Louw Architects, Urban Designer, Planner 26 URBAN EDGE GUIDELINES MANUAL CONSIDERATIONS B. PLANNING POLICY B1 To what extent does the development application support or contradict the vision and fundamental planning principles as set out in this document including those set out in the “Veldfire related planning guidelines” (Annexure 6).? COMMENTS / SUGGESTIONS • • B2 To what extent is the development application appropriate in its context. • • If the proposed development cannot endorse the vision and any of the fundamental planning principles as contained in the Structure Plan or Spatial Development Framework, then, at the most basic level, the application should NOT be supported. If the development is in conflict with the veldfire related planning guidelines (Annexure 6) it should not be supported. The development application and anticipated built form should be assessed in terms of the impact on the identity of the local areas as defined by the modified and natural landscapes and the various interrelationships that exist, with specific reference to scenic routes and gateways. If the development is in conflict with the veldfire related planning guidelines (Annexure 6) it should not be supported. MLH Architects and Planners in association with Piet Louw Architects, Urban Designer, Planner 27 URBAN EDGE GUIDELINES MANUAL CONSIDERATIONS B3 To what extent does the development application process support or contradict the veldfire related planning guidelines (Annexure 6) and the area-specific planning principles that deal with economic, social, biophysical and institutional sustainability? • • COMMENTS / SUGGESTIONS Development applications must take into account veldfire hazard if applicable. It is critical that development applications are sustainable and can prove this in both a local and area-wide context, considering all aspects of sustainability. MLH Architects and Planners in association with Piet Louw Architects, Urban Designer, Planner 28 URBAN EDGE GUIDELINES MANUAL CONSIDERATIONS C. URBAN EDGE GUIDELINES C1 To what extent does the Urban Edge need to be amended to accommodate the proposed development (e.g. proposed development outside the Urban Edge is considered to be urban)? To what extent should the veldfire related planning guidelines (Annexure 6) apply? COMMENTS / SUGGESTIONS • Applications that alter the Urban Edge require special scrutiny to justify such amendment. Follow through the evaluation to determine whether this modification can be justified. The current cadastrally based urban edge may exhibit anomalous situations. Where applications outside the edge are approved, this should only be done where major concessions to the natural environment can be made, including inter alia, the completion of ecological corridors and open space systems. The nature of the built form in such instances must reflect the logic of the decision to amend the edge and must comply with the other applicable considerations in this document. • Development within the cadastrally determined edge, that occurs in a situation which could be regarded as anomalous, should only be favourably considered where the nature of the development emphasises the natural state through, for example, landscaping and open space provision and the density of the proposed development. Care should be taken to ensure that the other applicable considerations in this document are addressed. Where necessary, require the application of the veldfire related planning guidelines (Annexure 6). • MLH Architects and Planners in association with Piet Louw Architects, Urban Designer, Planner 29 URBAN EDGE GUIDELINES MANUAL MLH Architects and Planners in association with Piet Louw Architects, Urban Designer, Planner 30 URBAN EDGE GUIDELINES MANUAL CONSIDERATIONS C2 To what extent does the development application support or contradict the policies as contained in the Urban Edge report? • COMMENTS / SUGGESTIONS If any of the policies are contradicted, then the motivation or mitigating circumstances should be fully explained. Should the argument suffice, the proposed development could be permitted subject to relevant conditions. C3 To what extent does the development application support or contradict the management guidelines as contained in the Urban Edge report for the relevant section of the Urban Edge? • If any of the management guidelines are contradicted, then the motivation or mitigating circumstances should be fully explained. Should the argument suffice, the proposed development could be permitted subject to relevant conditions. C4 To what extent does the development application take into account the Veldfire related planning guidelines (Annexure6). • If the proposed development is at risk from veldfires or could be a potential source of veldfires, the guidelines as set out in Annexure 6 should be enforced. MLH Architects and Planners in association with Piet Louw Architects, Urban Designer, Planner 31 URBAN EDGE GUIDELINES MANUAL CONSIDERATIONS D. SURROUNDING ZONING AND LAND USE D1 To what extent does the zoning define the character of the area in terms of permitted land use, minimum erf size, coverage, floor area ratio, building lines, height, etc.? D2 What restrictions are placed on the density of development by the surrounding zoning? COMMENTS / SUGGESTIONS • • Development applications that serve to enhance or reinforce the existing or established character of the surrounding area (as defined by permitted land use, minimum erf size, coverage, floor area ratio, building lines, height, etc. resulting in a particular grain and density of the surrounding built footprint) should be supported to the extent that the resultant character is deemed to be appropriate. In instances where the proposed zoning permits significantly different rights to the surrounding zoning, the development application will need careful assessment and convincing motivation. The unique character of a precinct should be celebrated and managed. However, care should also be taken to ensure that undesirable encroachment is not permitted. The density of development can contributes towards the character of an area. The proposed development should not exceed the density of the surrounding area unless this is demonstrated and agreed to be a positive contribution towards the character of the area. if not, the proposal may be required to change to a smaller scale of development such that the overall density of the immediate surrounds is not substantially increased thereby compromising the uniqueness of the precinct. MLH Architects and Planners in association with Piet Louw Architects, Urban Designer, Planner 32 URBAN EDGE GUIDELINES MANUAL CONSIDERATIONS D3 To what extent has the surrounding zoning changed in the past year? Five years? Ten years? D4 To what extent has the surrounding land use changed in the past year? Five years? Ten years? • • COMMENTS / SUGGESTIONS Rezoning legally entrenches changed land use rights. Changes in zonings (particularly in recent months or years) reflect a change in market forces that will probably be used to argue the inevitability of the proposed development and will be used as a precedent for future development applications. In order to be forward looking, care therefore needs to be taken to ensure that an unnecessary precedent is not set especially since zoning entrenches specific land use rights. Changes in land uses (particularly in recent months or years) reflect a change in market forces. This will probably be used to argue the inevitability of the proposed development and will be used as a precedent for future development applications. Sustainability requires environmental responsibility that is balanced with development that is both socially just and economically feasible. However, the land use also needs to be examined in terms of rights granted by the applicable zoning scheme. MLH Architects and Planners in association with Piet Louw Architects, Urban Designer, Planner 33 URBAN EDGE GUIDELINES MANUAL CONSIDERATIONS E. PROPOSED ZONING AND LAND USE E1 To what extent are the land use restrictions of the proposed zoning compatible with the land use restrictions applicable to the surrounding area? E2 To what extent do restrictions (if any) need to be placed on the permissible land uses within the proposed zoning? COMMENTS / SUGGESTIONS • Compatibility of land use is important to ensure that the uniqueness of character is maintained. Particular attention should be given to the potential of maximum development within a specific zoning, and the negative impact this could have on the surrounds. Proposed zonings that are substantially different from the surrounding zoning or have the effect of increasing the overall density of the area in an undesirable manner (e.g. in terms of permissible coverage) should only be approved with caution. • Care must be taken in terms of permissible and consent land uses granted within the proposed zoning. In this regard, the underlying informants that create the natural and modified landscapes and thereby define the character of the precinct need to be clearly understood. Should there be a particular land use (within the proposed zoning) that is undesirable in terms of the character of the area, then it should be expressly excluded in terms of a condition of approval. Similarly, restrictions or amendments that define the scale of development (e.g. setback, coverage, height, etc) may need to be enforced. MLH Architects and Planners in association with Piet Louw Architects, Urban Designer, Planner 34 URBAN EDGE GUIDELINES MANUAL CONSIDERATIONS E3 Based on an approved rezoning or subdivision, how can an undesirable ripple-effect be contained or managed? • COMMENTS / SUGGESTIONS It is critical to ensure that the ecological limits associated with the natural carrying capacity are respected and upheld. In this regard, the entire system (and the respective linkages) needs to be examined and the potential cumulative impact assessed. The conditions and specifics of a particular rezoning or subdivision application need to be carefully stipulated in order to prevent the setting of precedent that encourages urban sprawl. MLH Architects and Planners in association with Piet Louw Architects, Urban Designer, Planner 35 URBAN EDGE GUIDELINES MANUAL CONSIDERATIONS F. NATURAL ENVIRONMENT F1 To what extent do the natural characteristics of the site and the immediate surrounds determine the development potential of the site. (e.g. flooding, geological instability, fire)? COMMENTS / SUGGESTIONS • • F2 To what extent do the natural characteristics of the site and the immediate surrounds influence the surrounding community (e.g. flooding, geological instability, fire), particularly in the long-term? • • The Local Authority is responsible for ensuring short-term and long-term safety issues are adequately addressed. In this regard, it is important to ensure that the ecological limits of the natural environment are respected. If the anticipated impact on safety is significant when viewing the entire system in its context. The proposed development can be rejected on these grounds. Veldfire related planning issues as set out in Annexure 6 must be considered. The Local Authority is responsible for ensuring short-term and long-term safety issues are adequately addressed. In this regard, it is important to ensure that the ecological limits of the natural environment are respected. If the anticipated impact on safety is significant when viewing the entire system in its context, the proposed development can be rejected on these grounds. Veldfire related planning issues as set out in Annexure 6 must be considered. MLH Architects and Planners in association with Piet Louw Architects, Urban Designer, Planner 36 URBAN EDGE GUIDELINES MANUAL CONSIDERATIONS F3 To what extent do the natural characteristics of the site and the immediate surrounds influence on the long-term sustainability of the natural environment (e.g. groundwater discharge, impact on surface water runoff, maintenance of ecological corridors etc.)? • • COMMENTS / SUGGESTIONS The Local Authority is responsible for ensuring long-term sustainability issues, including downstream and upstream impacts are adequately addressed. In this regard, it is important to ensure that the ecological limits of the natural environment are respected. Issues such as floodlines and water levels (including the effect of sea level rise and coastal erosion) should be taken cognisance of. If the overall anticipated impact is significant when viewing the entire system in its context, the proposed development can be rejected on these grounds. It is critical that any development respects the ecological limits and displays concern for the long-term future of the area and, where possible, expands ecological corridors or protected natural environments. Subdivision applications that divide corridors or protected natural environments should therefore be carefully assessed. Veldfire related planning issues as set out in Annexure 6 must be considered. MLH Architects and Planners in association with Piet Louw Architects, Urban Designer, Planner 37 URBAN EDGE GUIDELINES MANUAL CONSIDERATIONS F4 To what extent do the natural characteristics of the site influence the aesthetics or visual amenity/integrity of the local surrounds (e.g. ridgelines or steep slopes which have visual exposure, extent of cut-and-fill required, well vegetated area, protected natural environment)? • COMMENTS / SUGGESTIONS As far as possible, the specific uniqueness and character of the area should be retained. Development applications should take cognisance of the informants that create the uniqueness and specify how the negative impacts of the development on the aesthetics will be mitigated. Special attention should be given to the silhouette of the skyline and/or ridgeline and the use of roofing materials. Reflective roofs on steep slopes should not be permitted and orientation and extent of glazing carefully considered. If reasonable, these specifications should be included with the conditions. It is essential that these mitigation measures are both feasible and enforceable. It is critical that any development respects the ecological limits and displays concern for the long-term future of the area and, where possible, expands ecological corridors or protected natural environments. Subdivision applications that divide corridors or protected natural environments should therefore be carefully assessed. MLH Architects and Planners in association with Piet Louw Architects, Urban Designer, Planner 38 URBAN EDGE GUIDELINES MANUAL CONSIDERATIONS F5 To what extent does the development application remove or protect any threatened and endemic species: fauna and flora? F6 To what extent will the proposed development rehabilitate the environment or require the environment to be modified in terms of the veldfire related planning guidelines (Annexure 6)? • • COMMENTS / SUGGESTIONS Sensitive natural habitats that create a particular character or uniqueness should be protected and managed. Particular attention should be given to protecting and managing fauna and flora that is either rare and/or sensitive. Development applications should specify how the negative impacts of the development in this regard will be mitigated, and if reasonable, these specifications should be included with the conditions. It is essential that these mitigation measures are both feasible and enforceable. A commitment to rehabilitation, including the application of the asset protection zone and fuel modification principles if necessary, indicates accountability and a concern for the future. Development applications should specify the rehabilitation and veldfire related measures that will be applied in the specific development, and if reasonable, these specifications should be included with the conditions. It is critical that the measures are both feasible and enforceable. MLH Architects and Planners in association with Piet Louw Architects, Urban Designer, Planner 39 URBAN EDGE GUIDELINES MANUAL CONSIDERATIONS F7 To what extent does the proposed development remove land of high and medium agricultural potential from use for agricultural purposes? • COMMENTS / SUGGESTIONS It is important to respect the limited availability of the earth’s natural resources, including soil suited for agricultural production. While land not classified as being of significant agricultural value is frequently perceived as being suitable for urban development, this should not be seen as justification for the fragmentation of rural landscapes and urban sprawl. The permanent removal of high and medium potential land from agricultural production should not be encouraged. The subdivision of good quality agricultural land into nonviable farming units may remove it from agricultural production, and this should therefore be carefully examined. MLH Architects and Planners in association with Piet Louw Architects, Urban Designer, Planner 40 URBAN EDGE GUIDELINES MANUAL CONSIDERATIONS G. BUILT ENVIRONMENT G1 To what extent is the character of the area informed by the “grain” of the built form? Does this reflect a historical or cultural architectural theme? G2 To what extent does the scale, style, orientation, height and position of the proposed development on the site impact on the visual aesthetics of the immediate surrounds (i.e. impact on neighbours)? COMMENTS / SUGGESTIONS • The character of an area is reflected in the manner in which built form has responded to the natural and modified landscapes. Development applications that respect and acknowledge the historical or cultural character of the local architecture and significant elements of the local landscape should be encouraged. • Scale, style, orientation, height and position of the proposed development on the site contribute towards the character of the immediate surrounds. Consideration should also be given to the need for and duration of lighting on the site. In instances of subdivision where no particular built form is proposed, these issues still need to be considered in terms of permissible development and entrenched in conditions of approval. MLH Architects and Planners in association with Piet Louw Architects, Urban Designer, Planner 41 URBAN EDGE GUIDELINES MANUAL CONSIDERATIONS G3 To what extent does the scale, style, orientation, height and position of the proposed development on the site impact on the visual aesthetics of the local surrounds (i.e. impact on surrounding community, as viewed from local access road or main road)? • COMMENTS / SUGGESTIONS Issues relating to proposed built form (scale and style), height, setback, orientation and positioning on the site may need to be addressed should the proposed development impact on the character or uniqueness of an area when viewed from a local access or main road. Consideration should also be given to the need for and duration of lighting on the site. Although a specific built form may not be articulated for subdivision applications, these issues still need to be evaluated. The addressing of such issues should be included in conditions associated with the approval. In particular, scale and building design should be appropriate in sensitive and scenic settings. MLH Architects and Planners in association with Piet Louw Architects, Urban Designer, Planner 42 URBAN EDGE GUIDELINES MANUAL CONSIDERATIONS G4 To what extent does the scale, style, orientation, height and position of the proposed development on the site impact on the visual aesthetics of the metropole (i.e. impact as viewed from a national road or scenic route)? • COMMENTS / SUGGESTIONS Developments which negatively impact on the character of the region should not be permitted, particularly if visible from a national road or scenic route. In this regard, developments in close proximity to scenic routes and gateways should be carefully scrutinized. Consideration should also be given to the need for and duration of lighting on the site, particularly from a regional perspective. However, given an appropriate scale of development, with issues such as style, landscaping, boundary treatment, orientation, height and position on the site adequately addressed, developments of regional significance may be approved under certain circumstances, particularly if infrastructure associated with the provision of bulk utility services is required for the sustainability of the surrounding population. Although a specific built form may not be articulated for subdivision applications, these issues still need to be evaluated in terms of permissible development. MLH Architects and Planners in association with Piet Louw Architects, Urban Designer, Planner 43 URBAN EDGE GUIDELINES MANUAL MLH Architects and Planners in association with Piet Louw Architects, Urban Designer, Planner 44 URBAN EDGE GUIDELINES MANUAL CONSIDERATIONS G5 To what extent does the proposed development involve removal of vegetation, and over what period can reestablishment be anticipated? Is the removal and proposed reestablishment of vegetation consistent with the veldfire related planning guidelines as set out in Annexure 6? G6 To what extent does the internal road network support the maintenance of the Urban Edge and provide clear Edge definition? To what extent is the internal road network compliant with the requirements of the veldfire related planning guidelines as set out in Annexure 6? • • COMMENTS / SUGGESTIONS While it is important that development is socially responsible and stimulates equitable economic development, it should also be environmentally sound. If the proposed development requires the removal of established vegetation, special consideration should be given to rehabilitating the area with mature, hardy (preferably indigenous) plants suited to the local micro-climate such that the visual aesthetics of the area are restored in the shortest possible time. Such requirements may need to form part of the conditions of approval. Special attention should be given to the protection of established avenues, clumps and groupings of trees and the maintenance and extension of tree canopies. Any development adjacent to the urban edge should indicate a concern for the future. In this regard, the integrity of the Urban Edge should be maintained, and internal road network should be carefully examined in this regard to ensure that sprawl and incremental growth is not encouraged. The design of the road network should reflect a concern for policing of the edge, to provide access for fire fighting purposes, to provide access for maintenance purposes and to assist in promoting a “public” front to the edge. MLH Architects and Planners in association with Piet Louw Architects, Urban Designer, Planner 45 URBAN EDGE GUIDELINES MANUAL CONSIDERATIONS G7To what extent do the boundary details (e.g. walling, fencing etc.) and landscaping complement or reinforce the overall character and built form of the area? • COMMENTS / SUGGESTIONS While the need for security is recognised, attention should be given to boundary details such that significant historical and cultural features are integrated into the surrounding area in a visually pleasing manner. The landscaping should relate to the surrounding area and enhance the quality of the development. Rear or side boundaries should as far as possible, not face onto scenic routes. The nature, material and finish of boundary fences should be carefully considered so as not to negatively impact visually e.g. precast concrete fences should not be permitted along defined scenic routes. MLH Architects and Planners in association with Piet Louw Architects, Urban Designer, Planner 46 URBAN EDGE GUIDELINES MANUAL 4.4 DECISION BY LOCAL AUTHORITY On the basis of the sensitivity analysis and the detailed evaluation, the planner should be well-placed to formulate a response to the development application from the spatial planning perspective, with associated conditions as deemed necessary. Clearly, if the application is not compatible with the relevant planning policy, and there are no extenuating or mitigating circumstances that indicate otherwise, the development application should be rejected at a fundamental level on these grounds. Where the development application is compatible with the planning policy, the response to the specific characteristics of the site, including the response to the Veldfire Related Planning Guidelines, should be scrutinized. Provided the development proposals are considered to be consistent with the normative principles and appropriate to the characteristics of the site, the development application should be approved, with conditions emerging from the detailed evaluation. If the development proposal or built form response is considered inappropriate for the specific site, then the application should be referred back to the applicant for the resubmission of a proposed built form that is considered more appropriate for the site in question. MLH Architects and Planners in association with Piet Louw Architects, Urban Designer, Planner 47 URBAN EDGE GUIDELINES MANUAL CHAPTER 5: THE WAY FORWARD The Guidelines Manual provides the outline of a logical thought process and decision-making framework. It was prepared and tested through a public participation process and refined to produce a useable tool that will primarily assist local authority planners to make decisions regarding development applications outside the Urban Edge and inside the Urban Edge (in the Management Zone). The Guidelines Manual is also intended to provide consistency in decision-making regarding such applications across the Unicity. It is important to note that the decision-making process as defined in the Guidelines Manual is not limited to applications adjacent to the Urban Edge, but that the principles and thought process can be applied to the evaluation of other applications, particularly those that reveal a high degree of sensitivity in terms of the Sensitivity Analysis (i.e. close to scenic route, MOSS, etc). However, the Guidelines Manual should not be seen as a panacea to all development applications. The majority of applications received are straight-forward and a “gut-feel” response is fairly accurate. However, there are controversial applications that need to be responded to, and the decision-support system within the Guidelines Manual is developed to enable the local authority official to undertake a rigorous analysis and evaluation in this regard. The Guidelines Manual will also be a useful tool for new planners within the local authority, by providing pointers to issues that need to be considered. The usefulness of the Guidelines Manual to potential applicants should not be underestimated. It can provide clear guidelines regarding the information required by the local authority in assessing development applications and the type of response that can be anticipated in relation to various characteristics of the site and the proposed built form. Over time, as the decision-making framework is applied to development applications adjacent to the Urban Edge, so it can be anticipated that the Urban Edge may be modified on a piece-meal basis, depending on the type of development permitted on each site. Ultimately, as the Urban Edge is rigorously tested and redefined, so it will become more distinctive and defendable, ensuring that the unique Cape character is celebrated and sustainability is promoted. It is critical that the Guidelines Manual is read in conjunction with the area specific Urban Edge reports (2001) and in the case of the Peninsula, also the peninsula management zone report. These studies provide the context, starting point and management guidelines applicable to specific sections of the Urban Edge. Similarly, it is important that the local authority official is familiar with the current planning policies applicable to his or her area of responsibility. As new policies are prepared and adopted, so the application pro formas (included in Annexure 2 – 5) may need to be amended. Regardless of these minor adjustments, it can be argued that the thought process underpinning the decision-making framework should remain relevant. It is the responsibility of the local authority planners to use the tool provided in the Guidelines Manual to assist with and provide consistency in decision-making.

RESEARCH Prior to submission of a development application, the applicant should do the necessary homework; ascertaining what is permitted within the current land use rights, and whether the proposed application can be accommodated within the relevant policy parameters. The research is essential since it forms a basis for the preparation of the motivation. A step-by-step procedure is presented below that indicates how the pro formas should be completed by the applicant: 1. Select the appropriate pro forma for the relevant section of the Urban Edge: Helderberg, Peninsula, Northern or Melkbosstrand 2. Locate the property spatially – does it fall inside or outside the approved urban edge? What is the erf size? What is the current zoning and land use? 3. What is the type of application that has been submitted? This needs to inform the motivation, assessment and evaluation. 4. The summary information is recorded in the top right-hand corner to enable easy tracking of the application should the pro forma at any stage become detached from the motivation. The applicant should fill in the property description (erf number) and the applicants name and contact details (telephone number). 5. The pro forma is divided into various sections, of which the relevant policies and management guidelines need to be considered by the applicant. 6. The column entitled “criteria” lists those aspects that the application should consider; PREPARATION OF MOTIVATION The applicant is responsible for motivating the proposed development and associated change in or exercise of land use rights. The motivation should clearly explain the current land use rights, how this differs from the proposed rights and why the local authority should approve the application. Specific issues of possible contention should be clearly dealt with at this stage (e.g. traffic impact), with detailed investigations by relevant professionals if necessary. The application should also be supported by the various documents as stipulated by the local authority (e.g. title deeds, conveyancer’s certificate, locality map, etc). In addition, the local authority may require various summary forms to be completed in support of the application and as a means to track the application. COMPLETION OF THE URBAN EDGE PRO FORMA Pro formas pertaining to applications adjacent to the Urban Edge are included in Annexures 1 – 4, depending on the relevant portion of the Urban Edge. It is recommended that these sheets be completed by the applicant (in addition to any other forms prescribed by the Local Authority) since it provides a succinct summary of the information contained in the motivation with respect to the Urban Edge and ensures that the applicant has referred to the relevant policy and legislative documentation to substantiate the application. It can be argued that if the application and motivation is thorough, the information required by these pro formas should be at the fingertips of the applicant. The presentation of the information in this format therefore assists the local authority official in • Planning Policy: Overall planning policy (e.g. Urban Structure Plan, Metropolitan Spatial Development Plan) obviously applies. Other policies or studies (e.g. Spatial Development Frameworks) applicable to the specific locality may also apply. The Local Authority will inform the applicant which planning policies need to be referred to. MLH Architects and Planners in association with Piet Louw Architects, Urban Designer, Planner • • • • • • 7. Urban Edge guidelines: Generally one section of the Urban Edge will apply, but two or more sections may need to be considered when the application straddles two or more segments of the Urban Edge. Surrounding zoning and land use: Record the zonings of the surrounding properties and current land use. Depending on the context, the Local Authority may need to examine properties beyond the immediate neighbours. – this remains at the discretion of the Local Authority. Proposed zoning and land use: Record the proposed zoning and land use within that zoning. Natural environment: Tick those characteristics or features that apply to the site, and refer to the relevant legal and policy documentation. Built environment: Tick those characteristics or features that apply to the site, and refer to the relevant legal and policy documentation. Other considerations: Tick those characteristics or features that apply to the site, and refer to the relevant legal and policy documentation. The column entitled “Applicable legal and policy documentation” contains the minimum documentation that should be referred to for each criteria (row). In this regard, the applicable legal and policy documentation needs to be considered or applied to the specific application. It is important to remember that the list of policies (as indicated on the pro forma) is not exhaustive. As new policies are formulated and adopted, these need to be integrated into the list and appropriately referenced. 8. When reviewing the legal and policy documentation, the applicant should assess whether the documentation deals specifically with or makes reference to issues such as minimum erf size, restrictions on land use or built form, management guidelines, or any other significant input which may affect the application. The applicant should comment on what the policy says in this regard and how it substantiates the application. 9. The column entitled “Overall Evaluation” and the block entitled “Decision/Recommendation” are for official use only. These sections will be completed by the Local Authority Planner on review of the information contained in the pro forma. RESPONSIBILITIES OF LOCAL AUTHORITY PLANNER INITIAL REVIEW BY LOCAL AUTHORITY As indicated above, on receipt of the application, the local authority undertakes an initial review to ensure adequacy of the submission for detailed assessment and evaluation. In this regard, it is essential that the officials have an intimate working knowledge of the various relevant policy documents applicable to the site and can verify that these have been considered and referenced in the preparation of the motivation. The initial review by the Local Authority should also ensure that all the necessary annexures and supporting documents are attached. Applications that are incomplete will be referred back to the applicant, and therefore, only applications that are deemed to have adequate information for a more detailed assessment and evaluation will be accepted and processed. At this stage, the Local Authority will also decide which other departments or sections (besides spatial planning) should review, comment on and if necessary, approve (or reject) the development application. Copies will then need to be issued to these departments for their internal evaluation. It is important that the comments and conditions emerging from the other departments or sections are collated and interpreted and where necessary, incorporated into the final decision.
