one of the critical needs of citizens is access to the facilities to spend their leisure time usefully. These facilities are considered as one of the infrastructures in sustainable urban development. As most of citizens’ leisure time is spent in the streets or small parks without any special facilities, extending urban recreational places will meet human naturalistic needs.
