Map 04.11.2 Supplementary planning instructions

Areas with special urban-climatic drawbacks

For all block (partial) areas of the settlement area or all road sections with a less favourable and mainly with an unfavourable thermal situation, it is recommended to implement the measures. Apart from this, there exists for some open and green spaces a potential for improving their climatic ecosystem services (e.g. in the context of micro-climate diversity). The areas with a special urban-climatic drawback are those sections of the areas, for which there is a priority need for action because of high stress level, which can be covered in the scope of an urban sanitation or an urban redevelopment.

To be able to give concrete instructions for the three spatial units (settlement area, green/open spaces, road space) of the main map, a differentiation has been done below in the following six area categories (see Table 1). Four of these refer to the settlement area. One differentiates here between the function of living, trade/industry, public utility/special uses and core areas. A category of priority action space was assigned each to public roads, paths and places as well as green and open spaces. The evaluation is based on purely climatic aspects as defined in a planning instruction. A linking with further vulnerability factors is done in a further step (see Section "Areas with a special vulnerability as compared to the urban climate").

Tab. 1: Categories and methods for identifying the areas having special urban-climatic drawbacks
Settlement area Living WOZ* 10 or 21 as well as unfavourable thermal situation during the day and in the night
Settlement area Trade/industry WOZ 40 as well as percentile P90 of the class of unfavourable thermal situation during the day
Settlement area Public utility/special uses WOZ 50 as well as percentile P90 of the class of unfavourable thermal situation during the day
Settlement area Core area WOZ 30 as well as unfavourable thermal situation during the day and in the night
Public roads, paths, places Road sections Unfavourable thermal situation during the day as well as very high air stress caused by traffic
Green and open spaces Park | Green area | Town square | Promenade Type 53 or 54 as well as percentile P95 of the block (partial) area-space mean value PET 02:00 p.m.
* WOZ= Abbreviation for the categories of the structural uses, stands for "Living number"; detailed description see SenStadt 2010

Over all the area categories, 751 priority action spaces have been identified. The highest share in this is shown by the category "Road sections" at almost 60 %. To about one-third, the categories assigned to the settlement space are subsumed. The settlement type "Living" represents here the biggest group with 107 block (partial) areas. The remaining approx. 10 % falls on the category park | green area | town square | promenade (Figure 12).

It can basically be determined that areas with priority need for action have been identified in all districts. The spatial focus lies in the districts Mitte (relevant for all area categories) and Charlottenburg-Wilmersdorf (the road space is mainly significant here). In both these districts, almost 40 % of the areas to be sanitised on priority are located. A subordinated focus point are the districts of Tempelhof-Schöneberg, Marzahn-Hellersdorf and Freidrichshain-Kreuzberg. In the districts Reinickendorf and Steglitz-Zehlendorf, on the other hand, there are only a few hot spots (Figure 13 and Figure 14).
