PRELIMINARY CONDITIONS SUMMARY EXISTING SITE HYDROLOGY THE EXISTING SITE IS A 43 .7 ACRE DRAINAGE BASIN AT THE SOUTHWEST CORNER OF OAKESDALE AVENUE S.W. AND MONSTER ROAD THAT DRAINS TO AN EXISTING POND BEHIND THE ELAND DISTRIBUTION FACILITY. THIS POND SERVES AS A REGIONAL DETENTION FACILITY FOR THE BLUME PARCEL SEGRETATION. CURRENTLY, PARCELS 1 AND 2 ARE DEVELOPED WITH LARGE DISTRIBUTION AND MANUFACTURING BUILDINGS AND PARCELS 3 , 4A AND 4B ARE UNDEVELOPED WITH TREES, BRUSH AND WETLAND AREAS. THE EXISTING IMPERVIOUS AREA IS 15. 9 ACRES. SOILS ON THE SITE ARE A MIXTURE OF WOODINVILLE, PUGET, PUYALLUP AND BEAUSITE. SINCE THE MAJORITY OF THE SOIL IS WOODINVILLE OF THE HYDROLOGIC GROUP "D" AND HAS A MIXED USE OF MEADOW AND FOREST, A COMPOSITE CURVE NUMBER OF 85 IS USED IN THE DRAINAGE ANALYSIS CALCULATIONS. THE TIME OF CONCENTRATION THROUGH THE SITE FROM THE HILL SOUTH OF PARCEL 3 THROUGH THE CONTAINER CORPORATION DRAINAGE SYSTEM AND TO THE POND IS 33 .66 MINUTES (SEE EXISTING DRAINAGE BASIN MAP) . F.E.M.A. MAP 328 SHOWS THE SITE IN FLOOD ZONE AH WITH A 100 YEAR FLOOD ELEVATION OF 19 FOR THE GREEN RIVER. i -' TOW • GHP � 30 L �\ a '4Ve �. tip s ;y..1',�111+,.�.��iwye,Q` i . a ...., .. +�/ 1 `, Y L.c, j� '1' / � \'•.

A DEVELOPED CN VALUE OF 81 WILL BE USED FOR THE UNDISTURBED FOREST AREAS AND 98 FOR THE NEW IMPERVIOUS AREAS. THE FUTURE TIME OF CONCENTRATION FROM PARCEL 3 TO THE POND IS ESTIMATED TO BE 33.12 MINUTES. THE EXISTING POND WILL BE RETROFITTED WITH A PUMPED DISCHARGE SYSTEM TO CONTROL THE POND WATER LEVEL. THE PEAK DISCHARGE RATE WILL BE EQUAL TO 50o OF THE EXISTING 2 YEAR/24 HOUR STORM. THE PUMP CONTROL SYSTEM WILL BE SET TO MAINTAIN A POND LEVEL AT ELEVATION 11. THE OUTFALL WILL BE TO THE P-1 CHANNEL JUST UPSTREAM FROM ITS CONFLUENCE WITH THE GREEN RIVER. A MONITORING SYSTEM WILL BE INSTALLED AT THE RIVER TO AUTOMATICALLY SHUT THE PUMP SYSTEM OFF WHEN THE RIVER IS RUNNING AT THE 12,000 CFS LEVEL PER REQUIREMENTS OF THE GREEN RIVER FLOOD CONTROL ZONE DISTRICT. A 200 FOOT LONG BIOFILTRATION SWALE WILL BE CONSTRUCTED TO HELP TREAT THE STORMWATER RUNOFF PRIOR TO ENTERING THE P-1 CHANNEL. IN / c►wP Le VE „r'Jlff/ ''w-•�r_.:`..'^Q. IRI yI yEj •y �••• \..• fir.

However, high CN areas should not be combined with low CN areas (unless the low CN areas are less than 15% of the subbasin). In this case, separate hydrographs should be generated and summed to form one hydrograph.

(Low runoff potential). Soils having high infiltration rates, even when thoroughly wetted, and consisting chiefly of deep, well-to-excessively drained sands or gravels. These soils have a high rate of water transmission. B. (Moderately low runoff potential). Soils having moderate infiltration rates when thoroughly wetted, and consisting chiefly of moderately fine to moderately coarse textures. These soils have a moderate rate of water transmission. C. (Moderately high runoff potentiai). Soils having slow infiltration rates when thoroughly wetted, and consisting chiefly of soils with a layer that impedes downward movement of water, or soils with moderately fine to fine textures. These soils have a slow rate of water transmission. D. (High runoff potential). Soils having very slow infiltration rates when thoroughly wetted and consisting chiefly of clay soils with a high swelling potential, soils with a permanent high water table, soils with a hardpan or clay layer at or near the surface, and shallow soils over nearly impervious material. These soils have a very slow rate of water transmission. From SCS, TR-55, Second Edition, June 19M, Exhibit A-1.
