2010.3.31
The site and its surrounding area boast a rich natural environment, including rare species, together with a cultural landscape represented by Komyo-ji Temple and the beautiful natural landscape of mountains and hillsides. A local NPO has been very active in the area to support environmental conservation. In cooperation with local residents and the NPO, the project was conducted to create a safe area where people could live with peace of mind while conducting a careful study and adopting an approach of not causing any negative impacts on the environment the landscape.
In our planning and design works, we especially noted the following issues.
Construction will be done in phases to minimize the negative load on the natural environment
Introduction of meandering stream works to avoid the cutting of edible grass, such as Celtis, Quercus aliena,, wwhich are food for rare animals
Use of porous blocks and a gently sloping structure for structures to conserve as well as create the habitat for living creatures
Introduction of a large culvert for the check dam to ensure normal sediment movement and continuity of the stream
