Specific Development Plan: Understanding the objectives, definition and content

The Specific Development Plan (SDP) is an essential tool in planning and urban design. In this article we will look in detail at the objectives, definition and content of the SDP. Understanding these key aspects of the SDP will allow you to appreciate its role in creating attractive and well-designed neighborhoods.

I. Aims and definition of the SDP:

The SDP covers a portion of a municipality's buildable area and establishes general planning regulations. It sets out dimensional requirements, layout, building size and the development of public and private spaces. Its main objective is to ensure the harmonious integration of new developments into the existing urban fabric, thereby contributing to the attractiveness of the district. The SDP specifies and implements the regulatory provisions of the General Development Plan (GDP) for a zone or part of a zone.

II. Structure and content of the PDP:

1. SDP "Existing Neighborhood":

The SDP "Existing Neighborhood" aims at the integration of new constructions and their surroundings in an existing built-up area. It lays down urban planning prescriptions taking into account the essential characteristics of the existing built fabric. This type of SDP is prepared by the municipality and can only be modified by the municipality. It is prepared in parallel with the PAG and includes written and/or graphic dimensional prescriptions.

2. SDP (new neighborhood):

The SDP: "New Neighborhood" concerns the development of vacant land or the restructuring of a built-up area. It gives greater freedom to the developer, while being guided by the master plan of the PAG preparatory study. This type of SDP can be prepared either on the initiative of the municipality/state or on the initiative of the landowners or their agents. It is prepared by a qualified planner or developer.

III. Detailed content of the SDP:

The content of the SDP varies according to its type. The main elements of the SDP are as follows:

  1. Resources needed for maintenance:
  • Green spaces
  • Roads and soft mobility paths
  • Car parks
  • Rainwater drainage and retention basins
  • Landscaping
  1. Development of private land:
  • Gross built area, footprint, sealable area, private green areas
  • Execution of buildings, setbacks in relation to plot boundaries
  • Building size, heights, number of above ground and basement levels
  • Number of residential units
  • Types of above-ground and underground constructions
  • Shape of roofs
  • Shape of plots with tolerances
  • Parking spaces

The SDP may also include optional requirements such as building setbacks, housing types and mix, private outdoor spaces, easements, access, buildings and natural features to be preserved, walls and fences, and color and use of materials.

The Specific Development Plan (SDP) plays an essential role in the regulation and development of neighborhoods. By understanding its objectives, definition and content, you will be better prepared to participate in the urban planning process and help create harmonious and attractive communities. Whether integrating new development into an existing neighborhood or developing new neighborhoods, the SDP provides valuable guidance for successful urban design.
