Description
The park area Tylův sad, situated close to the Faculty of Science in the residential district of Slezská Ostrava, will undergo a complete revitalisation and change. The park will receive an optimized rainwater management, new walking paths, new greenery and the space will be equipped with new furniture and illumination. During the adaptations, unused asphalt surfaces will be removed and changed for soaking ones – compacted gravel and paved surfaces. In the central part of the park area a new meeting space will be created, which also can serve as lecturing space for students. The rainwater from the paved surfaces will be drained into a dead branch with an overflow intake. Woody plants, which might be dangerous for the park users, will be felled and unappealing shrubs will be removed. Most of the perspective greenery will stay. The whole area will get new park greenery, a lawn regeneration will take place, new trees and bushes will be sown, the park will get perennial and meadow plants. The park, currently serving mainly as a space for passing-by, will become a place for relaxation and leisure time.
Summary of project results
Tylův Sad, located near the Faculty of Science of the University of Ostrava, used to be a neglected small green space with no programme content. Before the implementation of the project, people just walked through the space and didn''t stay there. The condition and routing of the pedestrian paths was not optimal, the material used did not allow for rainwater infiltration, which contributed to the burden on the sewerage system. The furnishings were also dilapidated and inappropriately placed. The aim of the project was to implement the elaborated design for a new, modern and close to nature park that meets the needs of the citizens of Ostrava and the students of the University of Ostrava.
The main activity of the whole project was completely revitalize the Tylův sad park. The paved areas of the park were paved with clay and cobblestone pavements, the original impermeable asphalt surfaces were removed. Rainwater from the paved areas was diverted into a dead-end channel with an overflow culvert. We have removed unsightly shrubbery and enhanced the park with new greenery in the form of trees, shrubs, lawns, perennial beds and meadow. The project also included the replacement of the public lighting with LED light sources and a new wooden pier with an area of over 36 m², elevated above the surrounding terrain built of larch terrace planks with anti-slip grooves. We also placed aesthetically pleasing and maintainable furniture in the park, including bins for mixed and separated waste.
The project was a part of Ostrava''s strategic efforts to create blue-green infrastructure and to bring blue-green infrastructure closer to citizens. The main environmental benefits of this project are: 1) improved infiltration of rainwater through the creation of permeable surfaces, 2) reduced temperature in the local microclimate 3) reduced dust by capturing dust particles through the proposed greenery, 4) promotion of a better spatial structure of vegetation, 5) promotion of biodiversity by choosing a wider range of green elements (trees, perennials, flowering meadows and shrubs). The proposed range of perennials was based on the basic principles for establishing extensive plantings and is highly resistant to drought and temperature fluctuations.
The circle of people positively affected by the project is wide - the city of Ostrava has almost 300 thousand inhabitants and the majority of park users will be probably the inhabitants of Silesian Ostrava and surrounding districts (1/3 of the population of Ostrava). In the same time, the park also has a positive effect on the students of the University of Ostrava, who can use it as an outdoor classroom in addition to spending their free time. It can also be used for example by visitors of the Blue Pavilion Polyclinic or tourists heading to the Ostrava Zoo or the viewing platform over the Bazaly. The project achieved the desired adaptation/migration measure - biodiversity was enhanced with 10 new trees, 76 shrubs, almost 1,100 ground cover trees, almost 6,000 perennials and grasses, 1,750 bulbs and 57 ferns. Lawns were also established on the site - parkland, herbaceous and flowering meadow, totalling almost 3,000 m2. The planting has also helped to reduce dust and naturally act as shading and cooling for the whole public space. The dead-end channel offers space for the accumulation of rainwater that previously burdened the sewer system.
We have implemented the project as we planned. The unattractive park has become a dignified space that is close to nature and at the same time suitable for leisure. No unexpected complications arose during the implementation and therefore all the indicators we had set could be met. The Tylův sad Park will continue to be used as a public space after the end of the project''s sustainability.
