More City of Kelsterbach, open space development of the Südpark in Kelsterbach Landscape architecture services for the development of the Südpark in Kelsterbach including the renewal of the pond system City of Kelsterbach, open space development of the Südpark in Kelsterbach The Südpark, which opened in 1977/1978, is located around 2 km southeast of Kelsterbach train station and is between Frankfurt Airport and the southern settlement boundary of Kelsterbach. From 1935 to 1973 the area of the Südpark was used for gravel mining. After the gravel pit was closed, the pit was used as a landfill for construction waste and excavated earth and was closed from 1973 onwards. In 1975 the landfill was recultivated. In the contaminated sites file the area has the status "suspected contaminated site lifted". The park in the south of the town was created at the end of the 1970s and has since developed into one of the most popular local recreation areas in Kelsterbach. The approximately 11 hectare south park, with its play and sports areas and extensive meadows, is equally popular with children, young people and families from Kelsterbach and the wider region. A pond, barbecue stations, a kiosk and sanitary facilities extend the local recreation area. The spatial formation of the south park is characterized by valuable trees and bushes, open meadows and lawns. There are various deciduous and coniferous trees, mainly of the oak, maple, birch and pine species. The natural potential has not been fully exploited and the South Park has design and functional deficiencies. The park furniture is in parts outdated and very worn. Park entrances and parts of the path connection are not designed to be barrier-free. The accessibility, lines of sight and internal development of the South Park as well as the connection to the nearby Staudenweiher are to be significantly improved. The northern main entrance currently leads through an underpass under the "southern ring road" with a bridge structure. Access to the park is via a staircase or a stepped ramp. Access is not barrier-free and also acts as a barrier between the city and the park. The city of Kelsterbach plans to close the underpass and create a ground-level crossing with traffic lights over the "southern ring road". An engineering firm has already been commissioned to do the planning. The connection of the park paths must be taken into account in the planning by the landscape architecture office. The existing pond system is centrally located in the middle of the south park. Due to the landfill being closed in the 1970s, the possibility of seepage is difficult or in some parts even impossible. Furthermore, the location of the pipes and their dimensions are not clearly known. This particularly affects the drainage structure and the corresponding connecting shafts with bottom heights. This must be specified during on-site investigations. Detailed plans are not available here. Based on the survey data and the estimated water depths, it is assumed that the water level is constant at 100.60 m above sea level. The depths vary between 0.80 and 1.40 m. In the immediate vicinity there is a water playground whose water is fed into the pond. The pond is also fed by well water. The comprehensive planning for the redesign of the pond facility aims to maintain the original contours in accordance with the preliminary planning. This would create an expanded pond area of approx. 2,600m² (current pond area: 2,100m²). The volume of the existing pond is approx. 1,660m³ (information without guarantee). The valuable trees along the edge of the pond should be preserved as far as possible, and root areas should not be affected. The main aim of the redesign is to transform the pond into a largely self-cleaning ecosystem by creating shore zones with different types of banks. The city of Kelsterbach attaches importance to a qualitatively sophisticated development of the South Park with high open space quality within the specified budget based on the existing preliminary design.
