VSMP AMENDMENT #2 FOR WP0201300032
THIS AMENDMENT IS TO CONVERT THE SEDIMENT BASIN FACILITY IMMEDIATELY ADJACENT TO ROUTE 20
NORTH INTO THE PERMANENT WET POND FACILITY THAT WILL PROVIDE STORMWATER MANAGEMENT WATER
QUANTITY AND QUALITY CONTROL FOR THE 60.77 ACRE CASCADIA SUBDIVISION. THE NORTHEASTERN
PORTION OF THE POND BOTTOM AND THE EASTERN 2:1 POND UPLAND SLOPE WAS LOCATED IN CUT WITH
DEPTHS OF UP TO 30. SIGNIFICANT ROCK WAS ENCOUNTERED IN THESE LOCATIONS AT THE POND
ELEVATIONS, WHICH WAS FAIRLY HARD ROCK, BUT WAS ALSO FAIRLY RIPPABLE. THE CONTRACTOR RIPPED
AS MUCH OF THE ROCK AS FEASIBLE USING A HOE RAM BUT ENCOUNTERED REFUSAL AT BEDROCK. FOR
THIS REASON, THE PROVIDED POND VOLUME IS APPROXIMATELY 90% OF THE ORIGINALLY APPROVE PLANS.
THE PERMANENT POOL HAS BEEN LOWERED AND THE OUTLET STRUCTURES HAVE BEEN UPDATED SO THAT
THE STORMWATER FACILITY PERFORMS WITH THE INTENT OF THE ORIGINAL APPROVED PLANS AND
CALCULATIONS. PLEASE SEE SHEET 14 FOR THE UPDATED DESIGN DETAILS AND THE H&H CALCULATIONS
FOR COMPLIANCE WITH THE ORIGINAL APPROVED PLAN.
