Get through forest fire level

Answer from: Gadget Gal
Contain the fires by the water first with the help of the boat. Use the fireman with hoses to keep the trees cool while fires next to them are being watered. Equip the decontaminating guys with extinguishers and have the reach the forest and house near the water where the trucks can't reach. Once you can start freeing up the firemen with hoses from cooling stuff down move them over near the parking lot where they started keeping the fire from spreading. Work your way to containing the whole area by keeping half cool while trucks and men hose out fire. Make sure to have the cops get all the people standing around early so they don't get contaminated. The water plane should be there by now use it wisely. Cooling is the key in this level. I only got a bronze doing it this way. Good luck! This is the hardest level out of all of them!
