Miljöförutsättningar vid anläggande av snödeponi : Utvärdering av potentiella platser för ny snödeponi i Gävle

Sammanfattning: In wintertime, a large amount of snow falls on roads, streets and parking lots in Gävle. Snow from urban areas may contain pollutants from sources such as atmospheric contamination, traffic emission and de-icing chemicals. These pollutants accumulate in the snow during the winter and are released when the snow melts in the spring and summer. Besides logistic and traffic safety, snow-handling strategies are an important issue for the municipal organization in terms of environmental effects from the melt water. Today, snow plowed in urban areas of Gävle are being transported to a snow deposit in the harbor of Gävle, Gävle hamn. In the future, the current location are going to be used by Gävle hamn. Therefore, the municipality of Gävle are looking at five different alternatives for localization of snow deposit. To determine which of the five alternative locations are suitable for construction of snow deposit in terms of environmental conditions, this study examines the different locations in terms of recipient, geology, biological consequences, land use and surroundings. If one large snow deposit, designed similar to the current one in Gävle hamn, is chosen to solve the snow handling in the future, location number 3 Ersbo syd would be the best option. Location 1 Fredriksskans, 2 Duvbacken and 5 Kungsbäck, has god potential to alone and/or in combination with another location, serve as area for snow deposit. Location number 4, Ersbo telepylon, should not be considered as an alternative location for a snow deposit. There are possibilities for unconventional solutions, such as district cooling or even use the snow to infiltrate in the ridge, the chance to reverse the snow-handling problem to a resource is great. Creative solutions could be a possibility to cover and prepare for the eventual environmental challenges the future may bring.
