Q3-4 I heard that there are standards for slopes in Yokohama City. What is it?

Yokohama City has established two characteristic standards for development activities on slopes.
One is the standard of development permission such as restrictions on development activities (standards for slope green tracts) stipulated by the landscape plan.If the current land is a forest, the height of the law (glue) is restricted, It is required to secure land for proper planting.
The other is referred to as "restrictions on slope development activities" based on the Broom Condominium Ordinance. In the case of development activities aimed at "baseroom buildings" subject to the Ordinance, the intentional embankment is restricted and the location for greening is specified.
