This review formulates greenspace distribution in relation to topography. The fate of rain precipitation on land would be controlled by greenspace. In the event of rainfall, water evaporation and water use for plants tissue building were neglected and hence, the precipitation would be released to infiltration and runoff. It was found that stormwater runoff of nearly 50% precipitation could be reduced by the presence of greenspace and therefore, infiltration was equal to runoff. This came up to the relationship between greenspace area (Av) and slope of land (S) for a given city as Av = (fr/fi)*S1/2. Greenspace distribution would be larger on the steep of land than on the mild slope of land.
