In terms of the settlement character of Yalova, there are significant population differences between summer and winter due to the intensive use by people from Istanbul and Bursa metropolises, and its population considerably increases during summer. Transportation to these important metropolises in the immediate vicinity is achieved rapidly by sea buses. It is subject to the use of potential population on a daily basis due to transportation facilities and recreational opportunities. By the new zoning plan, no changes were made to the building density, however, decisions are taken about the traffic scheme, parking lots and stop usage, and the area to be used as the city center, which form a basis for the urban design works. The project area includes Yalova province, Yalova square, and its surroundings. The subject of this project, Cumhuriyet Square, was formerly used as a parking lot. With the new coastline landscape planning implemented in Yalova, the need for parking space in Yalova has been partially met. It is decided to re-design this area as a city square, therefore, this project has been prepared and submitted to the executing institution.
