The article defines the retention potential of a housing development based on the example of two estates located in Cracow. Runoff from the urban area was calculated using the maximum intensity method (MIM). Highly effective rainfall retention based on green infrastructure has been proposed. It has been shown that by using extensive green roofs and permeable surfaces, it is possible to considerably decrease stormwater discharge from the analysed estates, and thus improving natural retention within the range of 18.6% to 22.1%.

增加自然保留–解决当前城市地区气候变化的措施

本文以克拉科夫的两个房地产为例，定义了住房开发的保留潜力。使用最大强度法（MIM）计算了市区的径流。已经提出了基于绿色基础设施的高度有效的降雨保持能力。结果表明，通过使用宽阔的绿色屋顶和可渗透的表面，可以大大减少所分析屋苑的雨水排放量，从而在18.6％至22.1％的范围内提高自然滞留量。
