The given map illustrations the information about alterations took place in the layout of the coastal area which is known as Portland between 1950 and 2007
overall, it is clear that radical modifications were made in the coastal area. It can be seen that Portland was facilitated with a number of developments and became a commercial area over 57 years.
To begin with, the industrial area was replaced by a swimming pool and a small Park towards North West in 2007. During 1950 the only sea existed on North but in followings years it was facilitated by yacht Maria. The multi-storey car park was constructed on the left side of the road by shifting from the left side. The main road which bisects city in two parts remained unchanged.
Probing further, till 2007 new apartments were installed on a place of the car park on North East. Shops were opened on both sides of the road in place of Greenland. On the bottom of the shops, there was a place for accommodation and a new cinema was built in the South west. The greener space used for installing new facilities.
