The proposed Sapia Short Plat consists of approximately 47,916 square feet (1 .1 acres) of land located at 18311-116th Avenu e SE. This proposed project consists of subdividing an existing single family parcel (ta x pa rcel# 3223059014) into 7 lots total through the King County Short Subdivision Process. The existing parcel is zoned R-8-SO. The project site is located in the NW Quarter of Section 4, Township 22 N, Range 5 E , WM , King County, Washington and is shown on the vicinity map below. ~ ;r 180t'r SI SE 176th St ® "" ~ ~ !IJ a: ., C: ~ ~ • C E, ,i;, 0 ([) l..
