A new residential area with ca. 200 building plots is being developed on the ca. 11.6 ha site.

The "Am Hühnerstein" site is situated at the southeast edge of the suburb, on the far side of the Vilberler Straße. The site development plan is at a development stage. What is unusual about the project site is that the surface water from public paths and roads has to be managed close to the surface via gullies and connecting troughs within public green areas. The rainwater from private areas and the outside catchment areas will be drained via sewers and fed, together with the rainwater from the public areas, into the local existing receiving waters of the Erlenbach via a flow restrictor.

igr has been commissioned by the town of Bad Homburg to plan and implement the building of the rainwater and waste water sewers. igr has also been commissioned by the Bad Homburg municipal works to plan and implement the building of the water and heating supply pipes.

Within the scope of the engineering construction works, igr is planning a storage sewer immediately in front of the flood-relief structure on the Erlenbach. Flood risk data must be assessed for the entire site, and in particular for the underground garage sites.
