COMMENTS
PLAT
1) A portion of the sanitary sewer along the south side of 74th Street is outside of the
ROW. A minimum 2o' of easement centered over the pipe is required which requires
additional easement along the front of Lots 3 & 4, Block 2.
2 The benchmark shall use the 1929 Datura all sheets). All previous additions of
Kittredge Crossings were built using this datum. We suggest using the benchmark at
Top Nut Hydrant, NW Quad. 74th Street NE & Kahler Circle NE. Elevation = 960.82.
3 A 2o' wide wetland conservation easement is required around all wetlands. This is a
dedicated "No Mow Zone". Additional easement is needed along the east lot line of
Lot 6, Bloch 1.
