Tami,
The grading plan prepared for the proposed Susannah Farley Single Family Residence(SFR)to
be constructed on Mason County Tax Parcel No. 12320-10-93341 has been received and
reviewed by Public Works.
The 400 cubic yards of grading appears to be a reasonable estimate. The site plan leads to the
following areas of concern:
1) Fill receiving areas need to be cleared of vegetation and deleterious materials before any
fill material may be placed. Likewise,the"borrow"area(s)need to be cleared of vegetation
before material is removed for placement elsewhere on the property as fill material. The finished
grades(Cut& Fill slopes)need to comply with building department grading standards, including
setbacks from neighboring properties.
2) If any fill area will support, or be with 5' of a proposed structure,they should be placed as
structural fill and meet your department's minimum compaction requirements, including
compaction testing results if the fill becomes a structure supporting embankment.
3) Stormwater runoff from the developed property should be dispersed into naturally
vegetated areas wherever possible. Erosion and sediment are required to be controlled onsite
during construction.Neighboring properties are required to be protected from potential adverse
stormwater runoff impacts associated with construction activities.
I feel these concerns can be addressed as conditions on the grading permit. Please feel free to
contact me at County extension 461 if you have any questions regarding these comments,or if
you feel any features need further discussion or attention.
Sincerely,
Al n A. Tahja
