Jokikylä, Jokikylä residential area and park

General plan of the station area

Jokikylä residential area and park is one of the new residential areas according to the master plan of the station area. The plan for the Jokikylä area was refined with a reference plan, which was completed in the summer of 2020. The reference plan serves as a starting point for further planning.

Jokikylä reference plan

Riihimäki's urban development board, the city government and the city council presented their opinions on the further planning of the reference plan areas (Kov 16.11.2020 § 82). In the statement, it was presented that in the further planning of the Jokikylä area, it must be ensured that there is enough open line of sight to the river from Eteläinen Asemakatu.

Minutes of the city council 16.11.2020 November XNUMX

Based on the decision, the northernmost block along Eteläinen Asemakatu presented in the reference plan has been lightened by removing the northernmost building masses in order to maintain openness to the park and the river.

Vantaanjoki transfer

In the current situation, the Vantaanjoki River runs along the northern and western edge of the area. The transfer of the Vantaanjoki riverbed to the center of the area requires a water management permit issued by the Regional Administration Office (AVI). The general planning for the relocation of the Vantaan River bed, aimed at applying for a permit, was done in the fall of 2020. The Regional Administrative Agency of Southern Finland (ESAVI) has granted a permit for the relocation of the river at the end of 2021 (legal 1/2022).

You can find the master plan material for the transfer of Vantaanjoki on this website in the section Plans and survey materials.
