Kätcheslachpark
The Kätcheslachpark is a green space and sewage technology facility in the city of Frankfurt am Main in its north-western district of Kalbach-Riedberg . The central element of the approximately ten (according to other sources eleven) hectare park is a pond called Kätcheslachweiher with a system of moats . The waters are used for rainwater management - especially flood protection through drainage - for the neighboring housing estates and for other surrounding areas. The park is named after the adjacent Kätcheslach moat .
Location and history
The Kätcheslachpark is located in the extreme northwest of the Frankfurt city area, about one kilometer from the city limits. The green area with pond and ditches was set up from 2006 to 2010 in a hollow on the Riedberg . The park borders immediately to the north with the buildings of the Riedberg settlement built in the 2000s ; To the north of the park area lies the village of Kalbach, an older settlement core of the Kalbach-Riedberg district.
The design of the park is based on a contribution to a landscape architecture competition announced in 2002 . The award-winning design comes from the Berlin office of Weidinger Landschaftsarchitekten, and the building owners of the facility are the City of Frankfurt's Green Space Office and HA Hessen Agentur . The preliminary planning for the establishment of the facility began in 2003. The award-winning design shows that an extension of the park area to the west is part of the original planning, which is to create a landscape-architectural transition between the new settlement areas and the agriculturally used areas east of the site.
The Kätcheslachweiher pond located in the facility with an adjacent clarifier takes up about 8,000 m². The pond drains east into the eponymous water ditch Kätcheslach. After a stretch of about 800 meters, this trench flows from the right into the Kalbach , a right tributary of the Nidda, which flows northeast to the northeast .
Function and importance to water management
The Kätcheslachpark with its bodies of water is a facility that mainly serves to protect against floods through drainage and water treatment . In the park, several small rainwater retention basins collect surface water from roofs and sealed traffic areas in the Riedberg settlement - areas totaling 120 hectares, with around 6,000 residential units and designed for around 15,000 residents. The capacity of the entire system at normal high water levels is around 17,000 cubic meters. In the case of very high water levels, caused by heavy rainfall or meltwater , this value can be increased by a further 10,000 cubic meters (up to the upper edge of the bank of the pond).
The water collected in the smaller retention basins is led through ditches from the south and west into a clarification basin upstream of the pond to the west. There, mud and other sediments settle and can be easily removed. The bottom of the sedimentation basin is lined with grass grid stones to make it easier to remove the sediments. The sedimentation basin and the pond are separated from each other by a dam in which there are several pipe passages. The clarified water in the basin flows into the pond when it reaches a certain level. A viewing platform lined with gabions was set up for visitors on the embankment .
The basin and pond have a continuous normal water level between 1.5 and 2 meters. In order to avoid mixing surface water and groundwater in the pond, the bottom of the pond is sealed with building lime . Another pipe passage with a throttle structure is built into the eastern bank of the pond, which regulates the flow of water into the Kätcheslach trench . By restricting (throttling) the amount of water flowing off to a maximum of ten liters of water per second and hectare, flooding along the Kätcheslach and Kalbach are prevented.
Transport links
The Kätcheslachpark can be reached on foot or by bike via two signposted hiking trails: The Hölderlin path , a hiking trail between Frankfurt city center and Oberursel , is intended to commemorate the German poet Friedrich Hölderlin and leads through the park. The park is also a station on the Geopfade, a geoscientific educational trail set up by the City of Frankfurt and Goethe University . Several information boards explain the water management importance of the area. The nearest public transport stops are served by the U8 underground line operated by the Frankfurt transport company VgF , Riedberg stop , and by the VgF bus routes 26 and 29, Riedberg campus stop . Access to the park is barrier-free .
