General Data
Name of instrument Standardized formula for assessing "organic development" for residential areas (= Berechnungsvorschrift des "organischen Entwicklungsbedarfs")
Country DE
Spatial level local
Type Spatial planning instrument
Subtype Formal planning instrument
Description Particularly in municipalities of lower centrality, federal and regional planning limits new housing developments to the extent of so-called "organic development". This local demand is very difficult to assess for municipalities and often exaggerated assumptions concerning population and economic growth lead to excessive new land zoning. As part of the municipal land use plan, the municipality calculates the estimated future demand for residential areas according to a standarized formula based on restrictive assumptions concerning population growth and thus limits new zoning to reasonable thresholds, thus also avoiding the administrative and financial burdens of rezoning land (cp. entry on "Rezoning"). The calculation of local demand also provides valuable information for a regional differentiation of state subsidies for housing and construction.
General objectives Standardized and comprehensible operationalisation and implementation of superordinate planning provisions on local and regional level. Limitation of new housing developments to actual demand.

General assessment of strength and weakness Strength: Standardized calculation formula ensures the intersubjective and correct implementation of superordinate planning restrictions on local level and avoids unintended (or deliberate) miscalculations on local level.
Weakness:

Best practise example Project on experimental urban construction (ExWoST) by the German Federal Office for Building and Regional Planning on "municipal residential area concepts" / "Kommunale Wohnraumkonzepte"
Example Abstract The ExWoST-project provides funding for municipalities involved in drafting local housing concepts, which integrally combine issues of housing demand, land ressources and adaptive strategies
