Planning Objectives and Core Activities
The Zweckverband Interkommunales Gewerbe- und Industriegebiet Heidelberg-Leimen (Special-Purpose District Inter-Municipal Commercial and Industrial Area Heidelberg-Leimen) was founded by the two cities Heidelberg and Leimen on January 1, 2021.

Planning, developing and conceiving a joint commercial and industrial area by taking into account plots of land, plots of land that are to be zoned and plots of land that are not zoned on both municipality lands as well as areas of the two large plants Etex (formerly Eternit GmbH) and Heidelberg Materials (formerly HeidelbergCement AG) that will free up. In particular, settlement structure, use and development are to be reorganized – where required, based on urban planning. Special emphasis lies on taking into account environmental issues as well as the interests of local businesses.

Feasibility Study on Infrastructure Development
One of the main activities of the Special-Purpose District is optimizing transport infrastructure by building a new connecting road, which includes constructing a bikeway network, a new streetcar connection and studying the idea of building a suburban train stop on the Special-Purpose District’s territory. A first feasibility study by engineers Koehler & Leutwein from 2019 describes the construction of a connecting road “straight through the Eternit premises” from the federal state road L 594 on Heidelberg’s municipality land to the L 600 on Leimen’s municipality land as a significant relief for traffic congestion and as positive for the development of the inner areas of the Special-Purpose District’s territory. Further studies of Koehler & Leutwein have confirmed existing results. They have been summarized in a preliminary study from March 2020 as well as in an explanatory report from October 2021.

The Road to a Joint New Zoning Map
When the Special-Purpose District was founded, first planning objectives regarding the reorganization of existing urban development plans and regarding transport infrastructure were set down in a concept. Together with LBBW Immobilien Kommunalentwicklung GmbH (KE), we developed an urban development concept, which was approved by the Special-Purpose District Assembly in July 2022.
The inventory regarding environmental protection rules for the Special-Purpose District’s territory was completed in 2022. The Special-Purpose District puts special emphasis on climate protection. Based on the municipal heating plan, we will commission a separate expert opinion on climate protection and energy supply for the Special-Purpose District’s territory.
In May 2023, part of the Special-Purpose District’s territory was awarded funding from the urban development program of the State of Baden-Württemberg, amounting to EUR 3.2M. KE was charged with the preparatory investigations required for determining a neighborhood improvement area, which is set to be completed by spring 2024. July 2023 saw the first step towards creating a framework plan with the start of a cooperative planning process. Renowned planning agencies drafted urban development concepts for the Special-Purpose District’s territory, with a special focus on taking into account the transport infrastructure. In a second step, these urban development concepts will go into greater detail. The framework plan will be based on the results and objectives of the neighborhood improvement plan as well as the preparatory investigations.
Preparatory Zoning Map
With the foundation of the Zweckverband Interkommunales Gewerbe- und Industriegebiet Heidelberg-Leimen (Special-Purpose District Inter-Municipal Commercial and Industrial Area Heidelberg-Leimen) on January 1, 2021, the two cities Heidelberg and Leimen have conferred their planning jurisdiction for the Special-Purpose District’s territory to the Special-Purpose District.
The Special-Purpose District Assembly resolved to create a zoning map for the entire Special-Purpose District’s territory on July 13, 2021. Within the framework of preparing a zoning map applicable to the Special-Purpose District’s territory, the existing zoning maps of the Cities of Heidelberg and Leimen will be replaced and planning laws will be established for areas that are so far undeveloped. Future urban developments will be based on a consistent and coordinated planning concept. At the same time, the zoning map creates the basis for joint planning and developments set to optimize transport infrastructure. Where necessary, developments will be based on partial zoning maps to be able to react more quickly. The publication of the resolution to prepare a zoning map can be found here:

Existing Zoning Maps
Decisions on incoming building permit applications are made based on currently applicable zoning maps, insofar as they do not oppose the planning objectives of the Special-Purpose District.
An overview plan shows the areas where currently applicable zoning maps have been replaced.

Overview applicable zoning maps
There are three zoning maps that apply to Heidelberg municipality land:
Zoning Map Rohrbach: Commercial Area Rohrbach-Süd, amendments 6, 7 and 8
Zoning Map Rohrbach: Commercial Area Rohrbach-Süd „Health Center – Im Breitspiel“
There are five zoning maps that apply to Leimen municipality land:
Commercial Area North II, 1st amendment and new version
Commercial Area North III, 1st Section
Commercial Area North III, 2nd Section, Part 1
Commercial Area North III, 2nd Section, Part 1, 1st amendment
The administrative unit of the Special-Purpose District recommends consulting the relevant bodies before submitting a construction application. Please get in touch for further information.
Right of First Refusal
The statutes concerning a special right of first refusal according to § 25 of the Baugesetzbuch (German Building Code) apply for the plots of land located between the train line Heidelberg-Bruchsal and the federal state road (Landesstraße 594) on the Special-Purpose District’s territory. The right of first refusal concerning properties and plots of land is a legal instrument that supports and ensures an orderly urban development in accordance with the urban development plan.
