BASIC INFORMATION ABOUT REVITALIZATION PROJECT to the top

Im Raiser / Grenadierkaserne Germany, Baden-Württemberg, City of Stuttgart, northern city district Zuffenhausen,

PROJECT DESCRIPTION
In 1936 barracks were erected on the site. After WW II the US forces used the site until 1993. After the move off of the US forces the site gets back property of the Federal Republic of Germany. In this year the preparation of a legally binding land-use plan for the site was decided by the city.
In 1998 an idea and realization competition was awarded. On 21.05.1999 the City of Stuttgart bought the site except one building (no. 406). The demolition of the other facilities was carried out until summer 2001. The regeneration and the marketing of the site were carried out by a private development company.
The investigation of contaminated sites started already in 1993. In the course of the preparation of land for building unexpected contamination was found (12/2000). They had to be remediated during the construction works. 2002 first construction works started and first property sales as well as land development measures were initiated. Until 2006 237 housing units (121 funded terraced houses, 52 funded apartments, 64 terraced/double/single family houses) were installed for approximately 900 people.

TIME OF IMPLEMENTATION OF PROJECT
1993 - 2002

LESSON LEARNED
• Central Contact point very efficient for project communication, project management and information flow
• A detailed investigation of the potential contamination is a precondition to prevent delays and additional costs in the project implementation
• Parallel planning action (changing zoning plan and creation of new building plan) as well as participation of public and other stakeholders at an early stage saves time
• Beside state funding special local funds are very helpful to support the settlement of interest groups like young families

BEST PRACTICE IN DIFFERENT DISCIPLINES to the top

PROJECT MANAGEMENT
The private development company „Wüstenrot Städtebau- und Entwicklungsgesellschaft mbH“ was contracted as development agency. A central contact point at the city of Stuttgart was established for the internal and external information flow and organisation.
Two urban competitions were implementation:
1.) 1998 to figure out the type and dimension of future structural use (public offer of a reward for a urban ideas and realization competition for a family friendly residential housing on the basis of space and cost efficiency, ecology and energy saving combined with high quality) and
2.) four contract sections for construction works were awarded.

ECONOMIC
The planned costs of 40,520 Mio. DM increased to approx. 53 Mio. DM (22,9 % city, 50,9 % private/investors, 5,3 % state (state rehabilitation program, state program for inner urban housing), Federal Republic 20,9 % (90 % of costs for contamination = prize of sale of the property - 5,83 Mio €)
The City of Stuttgart had to cover additional 1,64 Mio. € for the remediation of the contamination. LAW: In May 1993 the City Council of Stuttgart decided to establish a legally binding land-use plan according to the urban master plan of the department for urban planning. As the site was in former times used as military area also the land use plan (zoning plan) had to be changed. In a parallel action the change of the land use plan and the establishment of the legally binding land use plan were implemented. After the public offer of a reward for the urban idea and realization competition the involvement of the departments and public agencies at an early stage optimized the process. In March 2000 the zoning plan and in November 2001 the legally-binding land-use plan came into force.

SOCIAL
Especially young families should be activated by the special programs of the city "reasonably prized housing" and the “building program for families”. The purchase of land as well as the costs for construction was funded for about 173 housing units. 3.5 Mio. € were provided by the City of Stuttgart 128.000 € by the state of Baden-Württemberg. These programs enabled costs starting at 200.000 € for a housing unit and around 510 €/m². Additionally a lot of owner-occupied houses could benefit from the “state residential building program” and the special program “inner urban and peri-urban living”.
The marketing was implemented by the development agency. Interested persons could register until middle of 2001 (600 persons), the allocation was in spring 2002. At the end of 2004 almost all units have been sold.

ENVIRONMENTAL
Early integration of environmental planning aspects (major function for climate and air quality, old deposits and contaminated sites, inside the drinking and mineral water protection area, short distance to groundwater)
• Preservation of existing natural areas to protect fauna, flora and save costs (green belts with high biotope quality, hedges, single trees and natural stone walls).
• Establish of additional natural functions (beds for special plants, reuse of organic material and natural stones with high quality, provision of possibilities for nesting sites)
• Innovative construction works (extensive green roofs, low energy houses, minimization of sealed area, infiltration of rainwater)
and contamination:
• after contracting the development agency the previous investigation activities were summarized and a target-oriented concept to provide a remediation plan was elaborated together with the department for environmental protection
• Unexpected contamination was found during the preparation of land for building. The remediation was carried out by excavation in parallel to the preparation activities. 95.000 t of soil, 100 % more than expected, had to be disposed.
• Additionally a remediation for the top soil was implemented in Nov 2001 due to security reasons of the inhabitants.
• Due to the contamination left in the soil the planned rain water infiltration could not be realized.
