Mattila, Tehtaankatu 5-21

The purpose of the site plan is to expand the existing industrial and warehouse area on the west side of Tehtaankatu in the direction of regional road 130 into an area without site planning. At the same time, the possibility of opening a new exit and street connection from the county road 130 at the Merkosenkatu exit between the county road and Tehtaankatu is being investigated. The purpose of the new connection (Sepänkatu extension) is to improve the accessibility of Mattila's industrial area and move traffic to the area away from the northern end of Tehtaankatu, where museums and a school are located. In addition, the connection will promote the east-west and south-north pedestrian and cycling connections of the area and regional road 130.
The site plan takes into account the location of the area in the groundwater area and partially in the groundwater formation area.

The City Council has decided to initiate the preparation of the Tehtaankatu 5-21 site plan and site plan amendment in connection with the approval of the zoning review on March 1.3.2021, 76 § XNUMX.
The area of ​​Tehtaankatu 5-21 site plan and site plan change is part of the defunct object of the previous years' zoning programs, the west part of Mattila.

The urban block areas of the planning area are owned by private landowners. The unzoned part between the block areas and regional road 130 is mainly owned by the city of Riihimäki. Some parts of the area owned by the city are leased for the use of operators in the area or are privately owned.

The site plan and changes to the site plan require agreements between private landowners and the city.

The station plan is drawn up as the city's own work.
