Dryer & boiler vent below deck

[David C. Macy]

Would you advise extending the vents to be relocated past the deck.

It is about 10-15 feet. Seems to me the dryer vent will build lint and the heat from the boiler vent will create moisture below, ice above & there already is about a 12 inch depression at the ground creating a negative grade from the moisture.

Today the home had a large ravine and steep hill at the back. I took off the plastic A/C cover & accidentally steeped on it & started to sled/ski/tobaggon down the hill. I am glad I have good balance & no one saw me.
