Brownfield cadastres should be accessible online and should include search functions for certain features of respective sites (such as road access, rail access, communication infrastructure, building regulations, possible contamination, size and site of plots and local contact persons).

Best practise example "Industrial carrousel", Municipality of Bretten
Example Abstract The municipality of Bretten, situated in the southwest of Germany, has initiated what it called an "industrial carrousel". Based on a cadastre of brownfield potentials, public sector institutions have resettled to brownfield areas, thus creating attractive vacancies for private businesses to relocate to the city. I)ndustrial enterprises have additionally been relocated to the fringe of the city, which again created attractive vacancies for less space-consuming high-tech enterprises in the core town.
