My question involves real estate located in the State of: Washington
-bought home in 2013
-discovered in 2016/2017 my stormwater and sanitary sewer utilities cut across into the adjacent lot which was undeveloped.
-subsequently my title company paid to have the 2 utilities relocated so the sanitary sewer now runs straight down my property and connects in an unmaintained right of way, and the stormwater pipe now makes connection to the outflow pipe of the catchbasin ON MY PROPERTY.
Now in 2020:
----the key thing here is the outflow of the castchbasin on the adjacent lot is a pipe which is 12-14" old brittle concrete which runs under the corner of my property
-this was undisclosed upon purchase of the property
-there previously was a garage in this area of my property and I plan to rebuild/remodel the garage using remnants of the garage foundation
-due to the existence of this stormwater pipe, my plans to develop this part of my property will be negatively impacted because of the County building setback requirements for a pipe of this size
-as well, there is new construction on 2 adjacent parcels and the County has allowed them to run all stormwater through this same pipe which now goes under MY property.
My question is, do I have a valid Title Claim relating to the existence of this large stormwater pipe running under my property? What particular remedies could I ask for?
