The Skokomish Valley site was visited January 25, 2007. The proposal is to import 490 cubic yards of fill material that will be used to protect the residence. Engineering calculations are provided with the proposal. The proposal to fill in the flood plain was discussed at our staff meeting. It was recommended that this grading permit be referred back to the building department to be reviewed by their consulting firm due to the complexity of the hydraulic analysis. Grading Permit GRD2006-00018 is being returned for review by the building department's consultant. No action was taken by Public Works. Please feel free to contact me at 724 if you have any questions regarding these comments, or if you feel any features need further discussion or attention.

Mr.Tozier is attempting to protect his home from flood damage by Importing fi7L The County has stated that they can issue Mr.Tozier a Land Modification Permit if he Is able to satisfy the courdles criteria. The criteria is paraphrased as such, 'The fill mist have no Impact on the nearest kisuraNe structure or his property lute,whichever comes first.' No Impact has been defined as 0.0499 feet rise in water elev.for a 101}year 2441our storm event. The County's Skokomish Rivet Comprehensive Flood Hazard Management Plan, KCA& inc.. Feb. 1997, and the Walker&Asso. DigftM terrain maps have been used as a reference. Cross section 32 shown on figure f�-2b.Volume 1, of the Flood Hazard Plan. At the 100-year flood everrt the calculated thsod elevation Is 33.43'. The 100-year Roar rate is 34.910 cfs. Cross section 32 is approximately 4,693 feet long and has an end area of 19,648 sq.fL. Assuming that the I00-year flood event produced a food crass sedton at cross section 32 with a constant, uniform flow and a flood elev_of 33.43 feet, Mr.Tozier s proposed plan could reduce the cross sectional area of 19,646 sq.fL by 234.18 sq_fL,and be in compliance.

As the water splits, it in effect'turns a comer', The calculated increase in water elevation caused try the water turning the corner is next to be analyzed. For a more accurate and reasonable review,the flood way has been reduced to a cross section being 160'wide, that puts the Tozier fill in the middle of the section.
