The City of Kent contacted the Assistant Manager of Easthill Apartments. They gave her this (see above).
106th Avenue S. is the southern entrance to our property. This letter is saying that it will be closed Monday, Tuesday, and Wednesday.
It is difficult to tell, but I expect 116 Avenue SE will be closed as well. This implies that the only way to enter the Easthill and Kenthill property plat will be to use the eastern entrance which is located along 109th Avenue SE.
