Enhancing Ecological, Functional, Social and Aesthetic Quality of Street Green Space by Planning Green Pockets

Abstract

City residents do not always have an opportunity to visit larger parks or nature areas on a daily basis as the rhythm of their daily life does not allow them to spend enough time in a natural environment. More and more time is spent on the way to the place of work or home. As well as tourists on visiting the city use main streets as touristic routes. On the one hand, major central streets affect ecological balance of the city due to the heavy traffic and contamination from it, but on other hand, they are mostly visited public areas because of the public transport and various public buildings and touristic objects concentrated there. Thus, street green space plays an important role in the city landscape pattern and often requires much more diversity of plantings, humane and safer environment than other areas of the city. Street green space can be very limited especially in the centre of the city with dense building areas or places where historic pattern of buildings does not allow to expand green areas. But it is possible to find small green spaces or green pockets in several places along the street. Green pockets that developed as multifunctional, ecological and aesthetical green spaces can compensate insufficiency of street greenery. The socio-economically active, medium-size city of Rezekne in Latvia has been chosen as a pilot area for the assessment of potential to develop green pockets along main streets of the city. The central street of Rezekne is the main axis of the urban landscape which provides access to the city from other regions, although it is historic heritage area with active public life. Unfortunately, within the development of the city there were needs to increase the flow of the main street by reducing the green space. Therefore, it was not possible to develop classic street greenery of tree alleys. Due to the random spatial structure of buildings along the main street, there are open spaces of different size and shape between or in front of buildings. Those are appropriate for development of green spaces. The approach of green pockets was adapted for the main street of Rezekne as a tool for enhancing ecological, functional, social and aesthetic quality of street green space. As well as, this makes it possible to give the street landscape a diverse and multifunctional image and provide necessary functions and environment for residents and tourists. The aim of the article is to analyse problematic issues of the greenery of major central streets of Rezekne and present an approach of green pockets as a tool for their solving.
