Construction of Järvenkallio, Järvenkalliokuja and Kalajärvenranta

Streets and trafficKalajärvi

The project consists of the construction of the new streets Kalajärvenkallio and Järvenkallionkuja, the renovation of Kalajärvenranta, and the construction of structures and service roads to control the rain and surface waters in the Kalajärvenranta recreational area.

Project description

New streets Kalajärvenkallio and Järvenkallionkuja will be built in the Kalajärvi area and the Kalajärvenkatu street will be rebuilt. The bearing courses of the Kalajärvenranta street will be replaced to correspond to the current regulations. Municipal engineering required by residential construction will be installed on the streets: stormwater drainage for rain and surface water, a sewer and a water main, casing pipes for electrical and communications cables, and street lighting will also be built. The implementation of the construction requires excavation. A pedestrian and bicycle way will be built on the other side of Kalajärvenkallio and Kalajärvenranta. The roadways and walkways will be asphalted. The roadside areas will be sown with grass.

Two stormwater block systems, into which the rain and surface waters of the stormwater drain in the Kalajärvenranta street will be directed, will be built in the Kalajärvenranta recreational area. In the recreational area, retention ponds will be built for runoff before it is directed to the Kalajärvi lake.

The aim of the two stormwater block systems and four stormwater depressions to be built in the area is to filter and purify the rain and surface water collected from the area and to decrease the concentration of detrimental elements in the Kalajärvi lake. A waste water pumping station will also be built in the recreational area. The pedestrian and bicycle ways to be built through the recreational area will also be used in the service traffic of the water service systems in the recreational area.
