EXISTING SITE CONDITIONS
The subject lot is located at 23927 104'h Avenue West and is comprised of approximately
0. 19 acres. The lot is currently undeveloped. The lot is bound on the North, East, and
West sides by single family residences and on the South side by the recent constructed
Lot C. Vegetation is mixed with scattered evergreens and brush. The site slopes mostly
west at a slope of approximately 3%.
EXISTING DRAINAGE
Drainage presently sheetflows following existing topography. There is no apparent
drainage system along the frontage of the proTerty. The nearest drainage system appears
at the intersection of 2401h Place SW and 104 Avenue West.
PROPOSED USE
The site will be developed into 1 single-family lot. Runoff from the rooftop and
driveway will be conveyed to individual infiltration trench sized for the developed runoff
from a 25-year design storm. Infiltration rates were obtained from Advanced Drainfield
Systems (see Appendix).
